Faw Pentium five good cars pony cute and hard core.

Micro-electric vehicles are rare in the streets of the north, but in the south, you will find that it is basically the world of micro-electric vehicles, and it shows a situation of a hundred flowers blooming. You can see Wuling Hongguang MINIEV, Geely Panda MINI, Chery Little Ant … All domestic cars move around the streets flexibly and become big toys for contemporary young people. FAW Pentium also decided to join this field, bringing a new car Pentium pony. As the name suggests, the Pentium brand hopes that the Pentium pony can bring fun-filled car life to young consumers with its cute, smart, lively and friendly image and loyal and reliable quality.

[Cute] The Pentium Pony adopts the mainstream design style of the same level in appearance, and the body adopts a square box shape. The two headlights at the front of the car seem to be big eyes, which together with the brand logo in the central position and the circular plaque on the front bumper outline a very round and lovely front face. The side roof, rearview mirror and side skirt are designed with contrasting colors to increase the layering. The tail shape echoes the front face, and it is equally embarrassing. Combined with the lovely cartoon interior, the Pentium pony exudes a lovely atmosphere inside and outside.

[Variable] In order to cater to the aesthetic trend of the new generation, Pentium Pony brings a variety of interior and exterior decoration color schemes. The exterior provides 6 lovely fruit car colors, such as Xiaoqing lemon, small cherry, small grape, blueberry, small lychee and pearl lychee, and the interior provides 5 fresh color schemes, such as Tiffany green, cherry blossom powder, glass blue, clear sky blue and time gold. Feel free to match your favorite colors, and the tide is changeable.

At the same time, the seat of the Pentium pony can be flexibly adjusted. The petite body adopts a three-door and four-seat layout, and the rear seats support proportional tilting. After tilting, you can get a large flat space of 300 liters, which is convenient for storing large items.

[Playable] We can easily feel the "playable" attribute of the new car through the internal cockpit of the Pentium pony. The whole center console is like a large game machine, and all the knobs and buttons of window switch, air conditioning control and radio control are designed on it. Then, a Lego building block splicing platform is set above the center console, which can be turned into a mobile phone bracket, or DIY to build instrument table ornaments with different themes.

[Reliable] In addition to the personalized design, Pentium Pony insists on practical and safe quality. Equipped with full LCD instrument panel, built-in reversing image function, the whole system comes standard with main driver airbag and new generation EPS steering system, which is helpful for safe driving and novice control. Another intimate design is that Pentium pony puts the glass water filling port under the front face charging interface cover plate, and it is convenient to add glass water without opening the front hatch cover. Power adopts rear single motor layout, with the maximum power of 20kW, which is suitable for urban transportation.

[Modifiable] A car, a style. In order to facilitate the user’s modification, Pentium Pony has reserved a lot of modification space in the body design, and will provide official modification parts later, so that users can complete the modeling modification at low cost as far as possible. At the previous auto show, Pentium Pony exhibited three modified versions, including the convertible top-cutting shape, which was very eye-catching.

The convertible version presents a very dynamic and cool visual effect under the blessing of laser-sensitive car film and integrated spoiler-tailed racing seat. The moderator of the game player plays the trend punk, and the elements such as metal brushed texture car film, roof suitcase and mirror wheel hub are quite rock-and-roll. PUPU’s co-branded model takes the cute pet style, and the gradual car clothes, multiple blade wheel covers and Q version of the rocket’s double tail turn into a passionate little black mask.

Write it at the end

The mini-electric vehicle market will be on fire because it can meet the short-distance travel needs of most ordinary people. High-frequency car scenes, such as commuting, sending children to school, and daily shopping, all need an economical and flexible car to complete. It may not be luxurious, it may not have that much space, but it must be low in car cost and small and easy to park.

Above all, Pentium pony has done it. Moreover, it gives more emotional value on the basis of practicality, and users can even regard it as a high-quality big toy with cost performance and attitude towards life. It is really a five-good car for healing. At present, the new car is still in the blind ordering stage, and it is expected to be listed as soon as possible.

Popular science: five viruses carried by animals and the global disasters caused by them

Carl Zimmer reads books on Phoenix.com.

In this paper, the discovery history of five kinds of germs that have been raging and spreading wildly in human beings is discussed, including HIV virus, West Nile virus, Ebola virus, SARS virus and MERS virus. What needs to be known is that although the greatest scientists in the world are still engaged in medical research intensively and have put forward many effective measures to suppress it, even if human beings are expected to completely eliminate these diseases, it is not yet. What we can do is to take the initiative to understand it.

01

HIV virus

From October 1980 to May 1981, five men in Los Angeles, USA, were admitted to hospital for the same rare pneumocystis carinii pneumonia.

This kind of pneumonia is caused by Pneumocystis carinii fungus, its spores are everywhere, and most people have inhaled it into the respiratory tract at some point in their childhood. But people’s immune system will quickly kill these fungi and produce antibodies to protect their owners for life. However, if this person’s immune system is weak, Pneumocystis carinii will get out of control, and the patient’s lungs will be filled with fluid and scarred. Pneumocystis carinii pneumonia patients have difficulty in inhaling enough oxygen, so it is difficult to survive. However, the symptoms of these five patients are not typical-they are all young men who were in good health before suffering from pneumonia.

At that time, no one knew that these cases would quickly evolve into the most horrible epidemic in contemporary history. In fact, all patients have immune dysfunction at the cellular level, and the initiator is human immunodeficiency virus (HIV), which is HIV. Later researchers discovered that this virus has been quietly infecting humans for 50 years. Since their discovery in the 1980s, they have continued to infect 60 million people and killed half of them.

HIV virus

HIV is well-known, but it is not contagious, and people are not easily infected with AIDS. Even if the patient sneezes next to you or even shakes your hand, you won’t be infected. HIV can only be transmitted through certain kinds of body fluids, such as blood and semen. Therefore, unprotected sex will spread the virus, and people will be infected if they lose blood contaminated by the virus; If expectant mothers are HIV carriers, they may also transmit it to unborn children; Some heroin addicts share needles with others. If others are AIDS patients, the virus is likely to enter his body through contaminated needles.

Once HIV enters the human body, it will attack the human immune system. Its target is an immune cell named CD4. When the virus gene and protein manipulate and gradually take over the whole host cell, these cells can be used to replicate more HIV viruses and infect more cells. At first, the number of HIV virus in the human body will increase rapidly, but once the immune system recognizes the infected cells, it will start a desperate blow, and the infected cells will be destroyed by the autoimmune system, and the number of viruses will decrease. At this time, the patient will feel that he has only a slight flu. The immune system can successfully wipe out most HIV viruses, but a small number of viruses will survive quietly and hide in CD4 cells to continue to grow and divide. They are calm as usual most of the time, and occasionally wake up again, releasing a wave of viruses and infecting more cells. Although at this time, the immune system will rush to suppress the sudden small attack, but repeated many times, the immune system will eventually be exhausted and completely collapsed.

The time of immune system failure varies from person to person, which may take only one year or as long as 20 years. But no matter how long this process takes, the day will come: the patient’s immune system can no longer do its job, and those diseases that could not harm healthy people will become fatal. In the early 1980s, a large number of patients with suspected pneumocystis carinii pneumonia flooded into hospitals, in fact, they were all infected with HIV.

In this way, before finding the virus, the doctor first saw the power of HIV. They named the disease Acquired Immunodeficiency Syndrome (AIDS) for short. In 1983, two years after people first observed AIDS patients, a group of French scientists really isolated HIV from patients, and more studies also confirmed that the source of AIDS was HIV. But at the same time, in the United States and other countries, AIDS cases have emerged one after another, and in just a few years, it has become a global killer, and it has also become a mystery in the field of epidemiology.

It took scientists 30 years to figure out the root cause of AIDS-

In 1985, scientists tried to add HIV antibody to the serum of monkeys with similar symptoms, and as a result, they actually "fished" a new virus, which was named monkey immunodeficiency virus, or SIV for short. Scientists concluded that HIV may have evolved from one of the SIV viruses, but which one was unknown at that time.

In 1991, a scientist found a virus very similar to HIV in mangabey, West Africa. Later, new research showed that HIV was not of a single origin, and scientists divided it into two types, named HIV-1 and HIV-2 respectively. Among them, HIV-2 evolved independently from SIV virus carried by mangabey, and the source of HIV-1 is still confusing.

But HIV-1 is the main culprit of AIDS, and it took longer to find out the source of HIV-1. Relevant researchers have divided all the HIV-1 viruses in the world into four groups, among which 90% of AIDS is caused by M group virus, and other virus strains belong to N, O and P groups respectively, with a small number. After long-term research, it was not until 2015 that the life experiences of all four groups of HIV-1 viruses were settled. They came from Cameroonian gorillas mainly living in African forests.

Obviously, when scientists discovered HIV in 1983, the virus had become a potential global disaster; When scientists finally started to fight back, the virus had already occupied the first-Mover advantage. In the 1980s and 1990s, the number of people who died of AIDS kept rising. Some scientists are optimistic that a vaccine against the virus can be developed quickly, but a series of failed experiments have dashed their hopes.

It took many years of human efforts to control the epidemic of AIDS. Public health workers have tried a series of public health policies, such as controlling the use of needles and distributing condoms, and achieved corresponding results. Since then, the advent of anti-AIDS drugs has played a great role in the human struggle against the virus.

December 1, World AIDS Day

Today, millions of AIDS patients are receiving cocktail therapy, which uses a series of drugs to interfere with HIV infection of immune cells in order to prevent the virus from replicating with immune cells. In countries with strong economic strength, such as the United States, these drugs have indeed enabled many patients to regain relatively healthy bodies. Government organizations and some non-governmental organizations have sent these drugs to poorer countries, and AIDS victims in these areas have been able to prolong their lives. In 2005, the death rate of AIDS reached the highest in history, and 2.5 million people lost their lives that year, but the power of the virus has been weakened year by year since then. By 2013, the number of people who died of AIDS had dropped to 1.5 million.

Theoretically, we can make this number zero. Aids vaccine is still the best hope to achieve this goal, and recent research has rekindled people’s hope that an effective vaccine may be just around the corner. The widespread use of anti-HIV drugs can also effectively control the number of viruses in infected AIDS patients. At the same time, researchers are actively exploring, hoping to find the fatal weakness of these viruses.

Now human beings have a very deep understanding of HIV, and we even know the molecular changes that the virus has made to adapt to human beings in the past 100 years. It is entirely possible for us to destroy these adaptive traits one by one on this basis. In other words, the future of AIDS prevention and treatment, the answer may be hidden in its past.

West Nile virus

In the summer of 1999, some crows died strangely in the Bronx Zoo Park in new york, USA. Then, three flamingos in the zoo died suddenly, followed by a pheasant, a vulture and a cormorant.

At the same time, doctors in Queens, new york discovered a number of cases of encephalitis, the number of which is worrying. Usually, there are only 9 cases of this disease in the whole city of new york a year, but in August 1999, there were 8 cases in Queens just over a weekend. As summer passed, more cases appeared. Some patients were paralyzed by severe fever. By the beginning of September, 9 deaths had been reported.

On the one hand, doctors in Queens, new york are still worried about the strange diseases that broke out in the crowd. On the other hand, Tracy McNamara, chief pathologist of Bronx Zoo, got the answer to the question first. She suspects that it may be the same pathogen that causes the bizarre death of people and birds. Under her persuasion, the Centers for Disease Control and Prevention (CDC) began to analyze the genetic material of the virus. On September 22nd, researchers were surprised to find that birds didn’t die of St Louis encephalitis, but the real culprit was a pathogen called West Nile virus. This virus not only infects birds, but also affects people in parts of Asia, Europe and Africa.

At the same time, public health workers are still deeply puzzled by the inexplicable cases of human encephalitis and decide to search deeply. Two research teams have successfully isolated the genetic material from the virus that infects humans, and confirmed the type of virus-the West Nile virus that infects zoo birds actually killed people. This result also surprised researchers. In North and South America, no one has ever been infected with this virus.

Yellow virus, West Nile virus is one of them.

The United States is the birthplace of many kinds of human pathogenic viruses, some of which are ancient and some are new types of viruses. About 15 thousand years ago, human footprints reached the western hemisphere, and they brought a lot of viruses with them. When Europeans came to the New World, they brought a second wave of viruses. New diseases, including influenza and smallpox, swept across the American continent, killing millions of Native Americans. Since then, more new viruses have poured in. In the 1970s, HIV was introduced into the United States, and at the end of the 20th century, West Nile virus became a new "immigrant" in the United States.

It is only 60 years since the West Nile virus was first discovered by humans. In 1937, a woman in the West Nile region of Uganda began to have a strange fever. She came to the hospital, and the doctor isolated a new virus from her blood and named it after the discovery area. In the following decades, scientists found the same virus in many patients along the eastern Mediterranean coast, Asia and Australia. However, they also found that this West Nile virus does not mainly rely on human survival, but infects many kinds of birds and uses them to multiply and multiply.

At first, people didn’t know how the West Nile virus spread between people, birds and birds, or birds and people. It was not until scientists found the virus in a completely different species that the truth came out. This mysterious creature is the mosquito, which almost gives the virus a "wing"-when a mosquito carrying the virus bites a bird and sucks blood, it will inject its saliva into the wound of the bird’s skin, and at the same time inject the West Nile virus, which will multiply rapidly in the bird in a short time.

Studies on the genes of West Nile virus show that it originally evolved from Africa. Birds migrate from Africa to other parts of the Eastern Hemisphere, spreading the virus to new bird species and infecting humans. From birds to mosquitoes to birds, West Nile virus spread throughout the United States in just four years. At the same time, the virus also "landed" on millions of people, and only about 25% of those infected will have fever symptoms. Scientists estimate that from 1999 to 2013, more than 780,000 people were infected with West Nile virus, of which 16,196 developed encephalitis and 1,549 died.

After the West Nile virus arrived in the United States, it entered a stable life cycle, and the rhythm of this cycle was controlled by the life history of birds and mosquitoes. When chicks are born in spring, mosquitoes carrying viruses bite them. As a result, the number of birds infected with the virus continued to rise throughout the summer; New mosquitoes infect the virus by sucking the blood of these birds, and then bite people; People often spend more time outdoors in these relatively warm months of the year, and are more vulnerable to mosquito bites, thus being infected with West Nile virus.

Now that the West Nile virus has been integrated into the ecological environment of the United States, it may be difficult to kill them all. Even if doctors can develop vaccines to prevent humans from becoming the host of viruses, they can still thrive with the help of birds. Unfortunately, no West Nile virus vaccine has been approved at present, and probably never will be. Because although the virus infects many people, only a small part of them will develop encephalitis, and even fewer people will die from encephalitis. The cost of widely vaccinating Americans is extremely expensive, far exceeding the cost of treating those infected.

After arriving in America, the development prospect of West Nile virus is "optimistic". This is a warm and humid continent, and when the rainfall is heavy, the humidity and temperature are high, the epidemic situation is more likely to break out. Warm, rainy and sultry weather makes mosquitoes breed faster and lengthen their breeding season. At the same time, this weather can also accelerate the growth of viruses in mosquitoes. It seems that the West Nile virus has settled in this new continent, and our "efforts" are also making this home more comfortable.

Ebola virus

On December 2, 2013, a 2-year-old boy fell ill in the village of Meriando in southeastern Guinea. The child, Emil Wamuno, first had a fever, and then he began to vomit violently, accompanied by jet diarrhea and blood in his stool. No one in Meriando has seen similar symptoms. His family tried their best to take care of him, but by December 6, the child was still dead. It was a virus that killed the boy. When he died, the descendants of the virus had spread to other family members. Soon, Emil’s 4-year-old sister developed the same symptoms and died. Then the boy’s mother and grandmother. They probably got infected through the cruelest way we can think of-taking care of the dying boy.

If the virus stops here, this family tragedy is likely to be unknown outside the village of Meriando. Many people in Guinea die from viruses and other pathogens every day, but this virus is completely different. It is extremely deadly, and 70% of infected people will eventually die. The boy’s family has transmitted the virus to a nurse and the village midwife. After they got sick, the midwife was taken back to her hometown, and the virus continued to spread further by taking care of her family. At the same time, some people came from other villages to attend the funeral of Emil’s grandmother, and when they returned to their respective villages, they also fell ill.

Soon, the epidemic began to spread around the world. Meriando village is located on the border of Guinea, Sierra Leone and Liberia, and people often cross the border to do business or visit their families. The virus broke out in Sierra Leone and Liberia in a short time. However, because the disease is still concentrated in remote villages located in the tropical rain forest, the outside world is too lightly. It was not until March 2014 that the Guinean medical department finally announced that they had confirmed the culprit of the epidemic: Ebola virus.

Ebola virus under microscope

Some viruses are the old enemies of mankind. Rhinovirus began to make ancient Egyptians catch cold thousands of years ago, and endogenous retrovirus invaded the genome of our primate ancestors as early as tens of millions of years ago. There are also young people, and HIV only became a virus that can infect humans about 100 years ago. A large number of viruses have just begun to spread from person to person, triggering waves of new epidemics and arousing human concerns about new global epidemics. But of all these newly discovered viruses, none is more frightening than Ebola.

In 1976, Ebola virus entered the historical stage, and its first appearance showed its terrible lethality. In a remote area in Zaire (now the Democratic Republic of Congo), people began to have fever and vomit, and some patients were bleeding from all the openings such as nose and mouth, even from their eyes. A doctor collected a blood sample from a dying nun and put it in a thermos. Later, he sent the sample to Kinshasa, the capital of Zaire, and took it all the way back to Belgium by plane and gave it to the young virologist Peter Piot. Through the electron microscope, Pio observed a large group of snake-shaped viruses.

On high alert, scientists rushed to Zaire and finally arrived in Yambuku village to investigate the initial outbreak of the epidemic. There is a hotel here. Some nuns and priests are hiding in it. Visitors are blocked by ropes at the door. There is also a sign hanging on the rope, which reads: "Do not enter, entering may lead to death."

Soon, the Pio team found out how the unnamed virus spread. It turned out that the virus would spread from person to person. There is no evidence that this virus can float in the air like influenza or measles virus. In fact, it is spread by the body fluids of the victims. A local hospital used syringes repeatedly, and as a result, the virus spread to many patients. The staff who take care of the patients and wash the bodies of the dead are also sick.

Although Ebola virus is extremely deadly, its spread is relatively easy to cut off. Pio and his colleagues closed the hospital and isolated people with symptoms. After three months, the epidemic was controlled. 318 people died in this plague.

In the same year, Ebola virus appeared in Sudan, killing 284 people. Three years later, it made a comeback in Sudan, killing 34 people. Then it disappeared for 15 years, and in 1994 it launched an attack in Gabon, killing 52 people. Every outbreak has made Pio’s successors know more about Ebola virus. People gradually realize that as long as the patient’s whereabouts are tracked and properly isolated, new infections can be prevented. But they haven’t found a suitable vaccine, and they haven’t developed corresponding antiviral drugs.

Many viruses can suddenly break out when the conditions are right. But a virus like measles or chickenpox, once it breaks out, will not completely disappear from our bodies. It just hides in a low profile and spreads tepidly. The Ebola virus is different. When a plague subsides, it seems that the Ebola virus will disappear, but it will suddenly appear a few years later and launch a crazy attack again.

Some virologists are curious, where did the Ebola virus disappear in these years? Scientists have found that gorillas and chimpanzees are also infected with Ebola virus, and the mortality rate is very high, while bats have antibodies to Ebola virus, which seems to help bats coexist peacefully with the virus. Perhaps, under normal circumstances, Ebola virus will spread among bat individuals, but it will not cause any harm to them. Sometimes the virus will suddenly penetrate into human beings.

One thing is clear about Ebola virus: although we are completely unfamiliar with them, they are really an ancient virus. For millions of years, Ebola virus has been spreading in various mammalian hosts. They are harmless in some species, but sometimes they jump to other species and show a fatal side in these species. Humans are the latest target of Ebola virus attack. Meat or fruit contaminated by bat saliva may carry the virus, and people may be infected if they eat these contaminated foods. No matter by what route, once Ebola virus enters our body, it can quickly invade immune cells, leading to a serious inflammatory reaction. Patients will have violent diarrhea, vomiting, and sometimes massive bleeding until they die.

After Ebola virus enters a person’s body from an animal, its fate depends on the behavior of people around the victim. If people come into contact with infected people, they will be infected with Ebola and continue to spread to more people. In the first 37 years of human history, Ebola virus always disappeared by itself within a few months after a new outbreak, with the death or recovery of the host.

But in these 37 years, the living environment of human beings has changed. In the past, the sphere of influence of Ebola virus was generally confined to several neighboring villages, and it was difficult to spread to a larger scope. But now, more and more roads are cutting the rain forest, making people move to more towns, so that Ebola virus can find more hosts. However, in countries such as Guinea, Liberia and Sierra Leone, the development of public health is far behind the rapid urbanization. Years of civil war and extreme poverty have left few hospitals and doctors in these countries. When Ebola patients are taken to the hospital, medical staff will be infected and die first. The expertise needed to fight the epidemic in these countries is even more scarce.

No one knows how Emil, a 2-year-old boy, contracted Ebola, but the virus that spread from him to his family continued to make waves on a larger scale, triggering the largest Ebola epidemic in history. More people died in this plague than all those who died in the previous Ebola outbreak.

The virus then spread to Conakry, Freetown and Monrovia, the capitals of Guinea, Sierra Leone and Liberia. After a few months, there were no more Ebola patients in the hospital, and the patients were turned away or sent home to die. International health agencies are busy dealing with other epidemics such as influenza and polio, underestimating the extent of Ebola epidemic, and failing to provide help to West Africa that may slow down the epidemic. The governments of West African countries tried to isolate the affected cities and rural areas from their surroundings, but it didn’t play much role. The death toll soared, first 1000, then 2000, and then the number continued to increase.

Outside Africa, people know very little about Ebola, and their information mainly comes from literary works, such as the book Blood Epidemic: The Story of Ebola, which records a terrible virus attack, and movies such as Extreme Panic also make up many plots about the virus. Fear swept across the United States. A poll conducted in October 2014 showed that two-thirds of Americans were worried that the Ebola epidemic would spread to the United States, and 43% were worried that they were personally at risk of contracting Ebola. Rumors even say that Ebola virus can spread in the air. On October 23rd, it was reported that a doctor from new york who treated Ebola patients in Guinea returned to the United States and tested positive for Ebola virus. Before he developed symptoms, he had been to a bowling alley. Worried readers asked The New York Times if bowling could spread the virus. Reporter Donald McNeil Jr. quickly responded: "If someone leaves blood, vomit or feces on the bowling ball, the next person who touches the bowling ball will not even find these, and then touch his eyes, nose or mouth with his hand, which may be contagious." This is actually a euphemism, bowling can’t spread the virus.

Stills of Extreme Panic

Despite the public’s panic, the Ebola virus did not break out on a large scale in the United States. There are no other places. Nigeria used the public health measures used by Pio and others in other epidemics. As a result, the virus only caused 20 infections and 8 deaths before it died down. Senegal recorded a case without any death. Mali has also successfully controlled its epidemic. The reason why these countries have the upper hand in the confrontation with Ebola is that they have all been warned. On the contrary, the epidemics in Liberia, Guinea and Sierra Leone had spread silently before the outbreak, so they continued to be hit by the virus for a long time. In these three countries, the epidemic has expanded to an extent that cannot be easily controlled.

Epidemiologists watched anxiously as the number of infections soared, and they tried to predict how far the epidemic might develop. In September 2014, the Center for Disease Control and Prevention warned that there would be as many as 1.4 million Ebola cases by January 2015 without additional intervention.

Fortunately, some countries, including the United States, China and Cuba, began to send doctors and materials to African countries, and hospitals specifically for Ebola were built one after another. Public health workers also encourage people to bury Ebola patients in a safer way, so as to avoid being infected and dying themselves. Although the defense operation was carried out late and the measures were mild, by the end of November 2014, there was finally a turning point: the number of new cases in Liberia and Guinea began to decline. The following year, the epidemic quickly eased.

Although the Ebola epidemic has temporarily ended, it will not disappear forever. In September, 2014, ecologists and epidemiologists from Oxford University jointly published a research result, and made a detailed prediction on the location of Ebola outbreak in the future. They considered many kinds of animals that can carry the virus, as well as human settlements that overlap with the activities of these animals (such settlements are increasing). In their prediction, a total of 22 million people live in the Ebola risk zone. Although the probability that some of these 22 million people are actually infected with Ebola virus by animals is very low, once infected, the danger will be enormous.

SARS, MERS virus

Since the first discovery of Ebola virus, other viruses have also appeared. They have emerged from completely different places, which may be thousands of miles away from each other.

For example, in November 2002, a farmer from China came to the hospital with a high fever and died soon. Then, people in the same area appeared the same disease one after another, but at this time, the epidemic did not get worldwide attention until the disease infected an American. This man went to China to do business. On the plane flying back to Singapore from China, he suddenly started to have a fever. The plane stopped in Hanoi, and the businessman never left there alive. Although most cases are still concentrated in mainland China and Hongkong, people all over the world are getting sick. The death rate of this disease is as high as 10%, and it usually takes only a few days to kill people. This epidemic is brand-new in medical history, and it needs a new name. Doctors call it severe acute respiratory syndrome or SARS.

Structural diagram of SARS coronavirus

Based on the accumulated experience of HIV and Ebola virus, scientists suspect that SARS virus evolved from viruses that originally infected other animals. So they set out to analyze the viruses in animals that Chinese often came into contact with. Whenever a new virus was discovered, they added corresponding branches to the evolutionary tree of SARS. After a few months, scientists finally reconstructed the history of SARS.

The virus may have originated from bats in China, and one of them spread to civet cats, a mammal that looks like cats. Civet cats are common in the animal market in China. Humans may have become hosts in the process of buying and selling civets. It turns out that the biological characteristics of this virus just make them suitable for human-to-human transmission, and unlike Ebola virus, SARS virus can attach to tiny aerosol particles and spread in the air.

Although the SARS epidemic has spread beyond Asia, fortunately, public health measures to prevent the early epidemic of Ebola have also successfully subdued SARS. This epidemic has ravaged more than 8,000 people worldwide and killed more than 700 people. In comparison, the flu kills about 250,000 people every year-it can be said that we have successfully escaped a bullet fired by SARS at humans.

Ten years later, another coronavirus appeared in Saudi Arabia. In 2012, doctors in Saudi Arabia noticed that some patients suffered from respiratory diseases with unknown causes, and nearly one third of them died of illness. This disease is called MERS, which is short for "Middle East Respiratory Syndrome". Virologists isolated pathogenic viruses from patients and studied the genes of MERS virus. They used these genes to look for similar fragments in other species, and soon people’s eyes were fixed on bats in Africa.

However, how African bats became the fuse of the Middle East respiratory syndrome epidemic is still incredible. It was not until scientists studied the camel, a mammal on which people in the Middle East depend, that important new clues began to appear. They found that camels generally carry MERS virus. The virus is continuously released through camel nose secretions. A reasonable explanation for the origin of MERS is that bats may transmit the virus to camels in North Africa. Camel trade from North Africa to the Middle East is frequent, and a sick camel may have brought the virus to its new home.

Scientists have reconstructed the transmission history of MERS, and have every reason to worry that once MERS breaks out, the epidemic may be even more terrible than SARS. Every year, more than 2 million Muslims go to Saudi Arabia for the annual pilgrimage to mecca. It is not difficult to imagine that MERS virus will spread rapidly among dense people and then go to their homes around the world with pilgrims. Fortunately, so far, scientists’ fears have not come true. As of February 2015, 1,026 people were diagnosed with MERS, of which 376 died. Almost all cases occurred in Saudi Arabia, especially in hospitals. Perhaps MERS is best at attacking people whose immune system is weakened by illness. Unless MERS undergoes drastic evolution again, it may always be a dangerous but rare threat within hospitals in the Middle East.

If the epidemic doesn’t always come so unexpectedly (if we can make early warning of these emergencies), we can be better prepared and not caught off guard. However, the next time a virus is transferred from wild animals to human bodies, it is likely to trigger a large-scale epidemic, and we may know nothing about the pathogenic virus.

In order to make up for these cognitive loopholes, scientists are conducting more animal research to find the genetic material of the virus from their bodies. But we live on a veritable "virus planet", and the workload of scientists is huge. Among the new viruses they continue to discover, we don’t know which ones will cause plague, and it is even possible that these viruses will not pose a threat to human society. But that doesn’t mean we can just ignore them. On the contrary, we just need to be vigilant, so that we can take measures to stop them before they have a chance to enter our species.

Project introduction

Taihu Lake Basin is located in the core area of the Yangtze River Delta, and water environment management and water security guarantee are the keys to the high-quality development of the Yangtze River Delta region. The main diversion and drainage project of Xingou River is one of the key projects to improve the water environment capacity of Taihu Lake and implement the drainage of basin flood to the Yangtze River in the north. In order to realize the green concepts of land saving, energy saving and environmental protection in engineering construction, the research and application of key technologies in engineering construction are carried out in the aspects of scientific route selection of backbone water diversion and drainage projects, crossing of complex land and water transportation network trunk lines, ecological environment protection of rivers and lakes along the line, node hub pumping station system, and impact analysis countermeasures of urbanization process in engineering areas, and the following innovative achievements have been achieved:

1. In order to effectively deal with the problems of flood control in river basins and regional drainage water safety, improve the water quality of rivers and lakes, reduce pollution into lakes, and inhibit the outbreak of cyanobacteria, a construction scheme of Tongjiangda Lake backbone drainage channel is put forward, which integrates multi-functional requirements such as flood control, water diversion, drainage, navigation and fish crossing. In view of the characteristics of dense plain water network, shortage of land resources and rapid economic growth, the overall river layout with two lines of flood discharge and one line of water diversion is innovatively put forward, as well as the three-dimensional connection mode of control hubs along the line, which is coordinated with flood discharge, water diversion and navigation, to solve the functional requirements of sewage separation and high and low discharge;

2. The Xingou River trunk line water interchange (Xizhihu Port North Hub) adopted six reinforced concrete pipe jacking groups with the largest internal diameter of 4m in China to cross the Beijing-Hangzhou Canal and beijing-shanghai railway, developed the precise control technology and construction technology of large-diameter pipe jacking groups, and developed a new T-shaped diaphragm wall and high cantilever composite revetment structure, which solved the construction problem of Xingou River crossing the soft soil foundation of river network and the three-dimensional land-water transportation network.

3. In view of the shortage of land resources, complex river network and water system in the core area of the Yangtze River Delta and the requirements of the Yangtze River Protection for the water quality of the incoming river, the "one area, two ends, one line" ecological environment system management model adapted to the river network waters with strong human activities, and the river network ecological environment restoration technology of estuary+backbone river+capillary branch river+lake "point-line-surface" collection are innovatively put forward, which ensures the water quality of the Yangtze River discharged from Xingou River north and the ecological health of the basin;

4. A new type of bidirectional tubular pump with S-shaped blades and bidirectional inlet and outlet channels were developed, which solved the problem of improving the hydraulic efficiency of the ultra-low-lift bidirectional pump device, and a high-power two-speed motor was developed by using pole-changing technology, which improved the efficiency of the pump unit under the condition of wide variable lift and effectively reduced the energy consumption of the pump unit.

The research results of this project have been applied to the whole process of construction planning, design, construction and management of Xingou River diversion and drainage project, effectively serving the management of water conservancy, transportation, environmental protection and other industries and relevant government decisions, and achieved remarkable results.

Project introduction

In recent 20 years, there have been bank collapses in many sections of Jiangsu section of the Yangtze River, and the water level has repeatedly exceeded the warning water level, setting a new record for the highest water level in history, which seriously threatens the flood control safety, shipping safety and river regime stability in our province. River regulation projects such as bank protection and slope protection are the main ways to maintain stability in the rapidly changing area of the Yangtze River regime. Under the background of the great protection of the Yangtze River and the construction of ecological civilization, how to improve the implementation effect of the bank slope protection project and ensure the construction quality of the project is of great significance for maintaining the stability of the coastline and ensuring the safety of flood control.

Based on the research achievements of the joint application unit of this project in the past 10 years, the construction and scientific research units in the industry have carried out multidisciplinary joint technical research, aiming at systematically improving the effect of bank slope protection project and studying the key technologies of construction guarantee in Jiangsu section of the Yangtze River from the aspects of river regime influence mechanism, riprap protection type effect evaluation, riprap construction technology innovation, dike stability safety evaluation and ecological slope protection technology, etc., and achieved the following innovative results:

This paper reveals the response mechanism of erosion and deposition changes in a single sand pit to other projects, and puts forward a simulation method to accurately predict the riverbed to reach a stable state.

3. The panoramic view of the dike is obtained by using the sounding technology combining ground penetrating radar and multi-beam, and the complete shape of the dike is constructed by registration; The multi-temporal point cloud of dike is used to analyze the deformation of dike, and the feasibility of using point cloud for dike monitoring is clear. Based on fuzzy system and neural network theory, a deformation-based safety evaluation model of dike engineering is constructed. The deformation analysis software of point cloud is developed, and the three-dimensional change analysis of point cloud and the visual view of the results are realized.

4. The failure mechanism and process of geo-reinforced turf are proved, and the influence law of geo-materials and reinforcement technology on impact resistance is obtained; Through numerical simulation and field test, the erosion variation laws of two kinds of geo-reinforced turf at different flow rates are explained. A water erosion test system was designed to reveal the hydraulic erosion resistance characteristics of mixed turf. The in-situ sampling method of three-dimensional geo-reinforced turf was established, and the combined reinforcement effect of geo-mat, plant root system and soil was expounded.

Night economy, the more exciting the night.

  As night falls, the lights are on, and the colorful nightlife is gorgeous. Midnight Food Store’s delicious rice, dazzling fireworks show, the song and dance theater was packed … … Food, travel, shopping, entertainment, sports and exhibitions, with the continuous enrichment of consumption patterns, the "night economy" has become a new bright spot in many countries to enhance the vitality of cities and stimulate consumption growth.

  Japan: Night consumption is very rich.

  In downtown Tokyo, it’s not easy to have dinner, because you always have to wait. In Japan, the city after work is quite lively. "Night economy" has become an important engine to stimulate consumption and stimulate Japan’s economic development.

  When Midnight Food Store is mentioned, most people think of Japanese directly. Catering industry is called the second largest main industry in Japan after automobile manufacturing. According to the survey and research center of Japan Catering Service Association, the market size of Japanese catering industry reached 33.9 trillion yen in 2018. Among them, catering and accommodation business reached 20.8 trillion yen, and night consumption accounted for more than 60%.

  There are many kinds of night restaurants in Japan, including high-grade kiosks and popular small restaurants. Among them, the pub (izakaya) is the most common storefront in Japanese streets. Colleagues, classmates and teams can form "classmates’ meetings" and often get together for a drink. Japanese often say that wine is the lubricant of society. In many restaurants, you need to look at the menu to order food, but the drinks are all-inclusive and unlimited in one to two hours. The Japanese also love to "change places", and it is the best proof of the close relationship between friends that they turn around several pubs in one night.

  Recently, new tricks have appeared in Japanese restaurants. Kikkoman, a famous soy sauce manufacturer, has set up a "LIVE Live Restaurant" near Ginza, Tokyo — — In Kikkoman Tokyo Live Restaurant, the cooking masters demonstrated the cooking skills to the diners in the form of live broadcast. While cooking, they humorously explained the characteristics of the dishes, the origin of ingredients, nutritional value, cooking precautions, etc., and there was a TV presenter next to them to ask various questions. Similar new things are very popular, and many seats have been booked during the Olympic Games next year.

  In addition to catering, night cultural and recreational activities are also colorful. Theaters, cinemas and concert halls are the places where literary and art fans stay the most, and traditional Japanese plays and popular European and American plays complement each other. The late-night movie theater is a good place for people who are busy with work during the day and don’t want to miss the latest movies. A reporter friend of the author claimed that the newly released movies in recent years had hardly fallen, and asked him the trick. It turned out that after the newspaper cut off at 1 o’clock midnight, he was so excited that he couldn’t sleep, and he just went to the late-night cinema to refresh the film. Some cinemas will also offer discounts for ladies and multi-night packages to attract customers. In summer, zoos, aquariums, amusement parks, etc. will also open special night tours and have full-time commentators to attract primary and secondary school students to participate in night activities.

  In order to welcome the 2020 Tokyo Olympic Games, the Japanese government is making every effort to expand comprehensive services such as transportation, hotels, shopping and catering. Local governments regard nightlife as an important means to improve the competitiveness of cities. Mu Zengchong, director of Japan International Entertainment Industry Research Institute, said that local governments pay more attention to economic growth and have made great efforts to activate night consumption. Tokyo, Yokohama, Osaka and other cities have made brilliant efforts to develop local service industries.

  Shibuya, Tokyo is the birthplace of popular culture and a paradise for young people. There are many theaters and video game halls, and various cultural activities such as Japanese festivals and Western festivals continue. Yokohama gives full play to the advantages of a port city, and holds fireworks parties, masked parades and other activities. The go-kart race at night in Muzhang City, Chiba Prefecture is also very distinctive, attracting many young people from Tokyo to show their fists.

  In recent years, with the widening income gap of Japanese people, people’s entertainment and consumption situation also tends to be diversified. People of different classes and hobbies can find their own consumption places at night. Mr. Mu Zeng, a critic, said: "From the perspective of consumer psychology, most people have a higher desire to spend at night than during the day. At this time, people’s management of money bags is relatively loose."

  In Tokyo, trams, subways and other public transportation basically ended at around 1 am. Therefore, around midnight is called the third peak period after the morning peak and the evening peak. A few years ago, the governor of Tokyo once put forward the idea of 24-hour non-stop public transportation, but it has not been realized so far because of the cost of train and track maintenance and operation. Some passengers who can’t catch the last bus can only take a taxi home or find a hotel nearby to stay. In the future, with the popularization of autonomous driving technology, traffic obstacles that restrict night consumption are expected to be alleviated. It seems that there is still much room for development in Japan’s midnight consumption.

  Indonesia: "Midnight Shopping" is an addiction

  In Indonesia, as long as you bring enough money, "midnight shopping" will definitely make you addicted. "Midnight shopping" is a highlight of Indonesia, the fourth most populous country in the world, the largest economy in ASEAN and the third largest consumer market in Asia.

  During major festivals, the Indonesian Federation of Shopping Centers will organize shopping centers in Indonesia, especially in Jakarta, Surabaya, Yogyakarta, Bali and other cities to extend their business hours, usually until midnight or two or three in the morning, and some even until the next morning. In the days of "midnight shopping", there is often a "big traffic jam" when you leave the main road of the city in the middle of the night.

  The author, a friend who lives in the business circle of "Indonesia Square" in the city center, once got caught in the rolling traffic of "midnight shopping" when driving home from the New Year party, and was unable to move into the gate of his own community for more than an hour. Because it was New Year’s Eve, more than 250 businesses, large and small, in Indonesia Square were all open until after midnight.

  Just extending the business hours may not attract so many "night owl consumers". The "magic weapon" for Indonesian businessmen is to let consumers "chop their hands and feet" at a big price reduction. At the "Saturday Night Carnival" in BSD City, which just ended not long ago, merchants put out attractive advertisements of "Sincerity, limited time and 20% discount", and on the basis of discount, they also launched a "return when full" activity, with a maximum coupon of about 250 yuan RMB. Consumers can also participate in the lucky draw with the invoice, and the prizes are luxury business class trips in Paris, London and new york. So tempting, how can we not let consumers move? On the day of the event, this new shopping mall located at the entrance of the airport expressway actually triggered the wonder of the main road from the city center to the airport from the evening peak to midnight.

  In addition to discounts and lucky draws, Indonesian businesses also have "trump cards" — — Entertainment shopping. Amelia, senior manager of BSD City, said that in order to attract consumers, merchants would invite many famous singers and movie stars to hold "Bazaar the Artist" on the day of the event. Take the activities in BSD City as an example, consumers can watch the performances on the spot, chat with idols, take selfies and share their shopping mood. The mall also selected some local brand goods for on-site auction, and all the proceeds were donated to the orphanage.

  If you are not interested in stars, Indonesian businesses still have a bunch of "tricks" — — Parent-child brand, respect for the elderly brand, beauty brand, national style brand and so on. In the shopping mall, the children playing wildly in the children’s paradise were overjoyed; Uncle, aunt and even grandparents are out at midnight, singing loudly on the stage of "Good Voice of Indonesia"; In front of the counters of cosmetics and skin care products, well-known beauty artists design shapes and take care of makeup for "small owners" free of charge; There are also national fashion shows from hundreds of tribes across the country, which are novel and "spicy".

  In fact, "midnight shopping" or "night economy" is a microcosm of Indonesia’s national economy. According to the latest data from Indonesia’s Central Bureau of Statistics, Indonesia’s economic growth rate was 5.05% in the second quarter of this year, which has remained in the range of 4.9% to 5.3% for 14 consecutive quarters, with the global economic turmoil intensifying and emerging economies facing downward pressure. Among them, the contribution rate of household consumption to Indonesia’s economic growth has been close to 60% for a long time. In the second quarter, the growth rate of total consumption rose to 5.17%, slightly higher than the 5.02% in the first quarter, and the business confidence index also improved. The Bank of Indonesia issued a statement saying that Indonesia’s consumer confidence index is generally at its best level since 2000, and the inflation level is running at a low level for a long time.

  Some Indonesian economists predict that Indonesia’s per capita GDP is expected to exceed 4,500 US dollars in 2019, and it can reach 12,000 US dollars at purchasing power parity, which is second only to Brazil and China in the "National Club of 200 million people". Stimulating domestic demand and encouraging consumption is a major driving force for Indonesia’s economic growth.

  "This year ‘ Midnight shopping ’ I want to buy it! Buy! Buy! " Dai Wei, a 24-year-old Indonesian girl, told me that she had just found a job in a well-known mobile phone brand manufacturer in China, and she was more confident to participate in the midnight shopping spree.

  France: The Literary Style of "Night Paris"

  Say, a French economist, once said: "It is not good for business to encourage consumption only, because the difficulty lies not in the desire to stimulate consumption, but in the means to supply consumption." The characteristics of night economy in France, which is famous for its "Paris at night" model, fully verify this theory and bring diversified highlights to French economic development.

  At present, the mode of "Paris at night" in France is not only confined to the traditional fields represented by bars, restaurants and other single entertainment consumption, but also increasingly extended to more fields such as art, culture, deduction, retail and so on, making the charm of French culture and art more brilliant and eye-catching with the help of the mode of "Paris at night". Some French media commented that "Night Paris" lit up France.

  Light show, light up the city context with regional culture. Almost every French city regularly holds light shows with regional characteristics, and all kinds of creative lighting decorations are spread all over the corner, telling the historical classic stories of the city emotionally. This perfect combination of modern technology and traditional culture has become an important way for French people to enjoy leisure and tourists from all over the world to understand French customs.

  Among them, the light show in Lyon, the second largest city in France, is the most famous. In addition to the annual Lantern Festival in early December, Lyon also has colorful lighting in series with Notre Dame de Fourier, the old city, the river Thorne and other scenic spots, which makes Lyon glow with different brilliance under the night. As one of the "three major lighting festivals" in the world, the Lyon Lighting Festival began in 1852, originally to celebrate the completion of the gilded bronze statue of the Virgin Mary. In 1980, the municipal government of Lyon implemented the Urban Lighting Planning, which made lighting an important part of the urban landscape and connected it with history and culture, forming an international lighting festival with a more humanistic atmosphere. The four-day lighting energy-saving in Lyon attracts more than 4 million tourists every year, which effectively promotes the development of the tertiary industry such as local accommodation, catering and entertainment.

  Visit the museum at night and light the spark of thought with the light of culture. In Paris with the Louvre, cultural gluttony never disappoints people. After a busy day, cultural attractions at night are more attractive. Without the noise during the day, it is a pleasure to wander around the historic sites in quiet nights and enjoy the beauty of Paris gracefully at night.

  The French government has always attached great importance to the layout and management of cultural attractions and the innovation of cultural industries, and Paris has promoted the night economy with cultural industries as the core by extending business hours, increasing night performances in theaters, night tours in museums and extending subway operation hours. Every year, France organizes about 1,200 museums to participate in the "Night of European Museums", which is open for free until the early hours of the morning, and receives an average of more than 2 million visitors every year, including "big-name" museums such as Pompidou Cultural Center, Louvre and Orsay Museum. In addition to opening at night in a specific period, Paris’s theaters, museums and other cultural attractions have also extended their opening hours to varying degrees with the support of the government, making cultural consumption a characteristic label of Paris’s "night economy".

  Fireworks show, lighting up the sky with gorgeous fireworks. In addition to New Year’s Day, National Day and other important festivals, many scenic spots in France have also launched gorgeous fireworks shows, which make tourists feel different audio-visual feasts through the ingenious integration of lights, fountains, music and fireworks. As one of the five largest palaces in the world, Versailles has launched large fountains, classical music and fireworks displays in the summer.

  When night falls, the back garden of Versailles Palace is decorated as a gorgeous stage for the fire tree and silver flowers. Accompanied by the elegant melody of baroque music, the mirror pool, the water and the moon are dancing and dancing, and the light and shadow of the colonnade jungle are chasing each other, so that tourists can taste the Versailles where light turns to sound against the bright fireworks. The launch of the fireworks show also promoted the development of tourism in surrounding towns.

Make the market play a decisive role in resource allocation and better play the role of the government.

-Speech at the Central Economic Work Conference (December 15, 2012)

On making the market play a decisive role in resource allocation and giving full play to the role of the government. This is a major theoretical point decided by this plenary session. This is because the economic system reform is still the focus of comprehensive deepening reform, and the core issue of economic system reform is still to properly handle the relationship between the government and the market.

After more than 20 years of practice, China’s socialist market economic system has been initially established, but there are still many problems, mainly the irregular market order and the widespread phenomenon of seeking economic benefits by improper means; Factor markets’s development lags behind, with idle factors and a large number of effective demands not being met; Market rules are not unified, and departmental protectionism and local protectionism exist in large numbers; Insufficient market competition hinders the survival of the fittest and structural adjustment, and so on. If these problems are not solved well, it is difficult to form a perfect socialist market economic system.

To further handle the relationship between the government and the market is actually to handle the question of whether the market plays a decisive role or the government plays a decisive role in resource allocation. Economic development is to improve the allocation efficiency of resources, especially scarce resources, to produce as many products as possible with as few resources as possible, and to obtain as great benefits as possible. Both theory and practice have proved that market allocation of resources is the most efficient form. The market determines the allocation of resources, which is the general law of market economy, and the market economy is essentially an economy in which the market determines the allocation of resources. To improve the socialist market economic system, we must follow this law and focus on solving the problems of imperfect market system, excessive government intervention and inadequate supervision. The orientation of "making the market play a decisive role in resource allocation" is conducive to establishing a correct concept about the relationship between the government and the market in the whole party and society, to transforming the mode of economic development, to transforming government functions, and to curbing negative corruption.

China is implementing a socialist market economic system, and we still have to give full play to the superiority of our socialist system and the positive role of the Party and the government. The market plays a decisive role in the allocation of resources, not all.

To develop the socialist market economy, we should play the role of both the market and the government, but the functions of the market and the government are different. The decision of the plenary session puts forward clear requirements for giving full play to the role of the government, emphasizing scientific macro-control and effective government governance, which are the inherent requirements for giving full play to the advantages of the socialist market economic system. The plenary session decided to make arrangements for improving the macro-control system, fully and correctly performing government functions, and optimizing the government organizational structure, stressing that the government’s responsibilities and functions are mainly to maintain macroeconomic stability, strengthen and optimize public services, ensure fair competition, strengthen market supervision, maintain market order, promote sustainable development, promote common prosperity, and make up for market failures.

The plenary session decided to adhere to and develop the relevant expositions since the 15th National Congress of the Communist Party of China, proposed to actively develop the mixed-ownership economy, and emphasized that the mixed-ownership economy with cross-shareholding and mutual integration of state-owned capital, collective capital and non-public capital is an important realization form of the basic economic system, which is conducive to amplifying the function of state-owned capital, maintaining and increasing its value, and improving its competitiveness. This is an effective way and an inevitable choice to adhere to the dominant position of public ownership and enhance the vitality, control and influence of the state-owned economy under the new situation.

State-owned enterprises are an important force to promote national modernization and safeguard the common interests of the people. After years of reform, state-owned enterprises have generally integrated with the market economy. At the same time, state-owned enterprises have also accumulated some problems and disadvantages, and need to further promote reform. The plenary session decided to put forward a series of targeted reform measures, including increasing state-owned capital investment in public welfare enterprises; In the natural monopoly industries where state-owned capital continues to hold shares, the reform with separation of government and enterprise, separation of government and capital, franchising and government supervision as the main contents will be implemented, and the network transportation will be separated and competitive business will be liberalized according to the characteristics of different industries; Improve the corporate governance structure with coordinated operation and effective checks and balances; Establish a professional manager system to give full play to the role of entrepreneurs; Establish a long-term incentive and restraint mechanism to strengthen the accountability of state-owned enterprises’ investment; Explore and promote the disclosure of major information such as the financial budget of state-owned enterprises; State-owned enterprises should reasonably increase the proportion of market-oriented hiring, reasonably determine and strictly regulate the salary level, job treatment, job consumption and business consumption of managers of state-owned enterprises. These measures will promote state-owned enterprises to improve the modern enterprise system, improve operational efficiency, assume social responsibilities reasonably and play a better role.

To adhere to and improve the basic economic system, we must adhere to the "two unwavering". The plenary session decided to propose reform measures to encourage, support and guide the development of the non-public economy and stimulate the vitality and creativity of the non-public economy from multiple levels. In terms of functional orientation, it is clear that both public ownership economy and non-public ownership economy are important components of the socialist market economy and are important foundations for China’s economic and social development; In the protection of property rights, it is clearly stated that the property rights of public ownership economy are inviolable, and the property rights of non-public ownership economy are equally inviolable; In terms of policy treatment, it emphasizes the equality of rights, opportunities and rules and implements a unified market access system; Encourage non-public enterprises to participate in the reform of state-owned enterprises, encourage the development of mixed-ownership enterprises controlled by non-public capital, and encourage qualified private enterprises to establish a modern enterprise system. This will promote the healthy development of the non-public economy.

To adhere to the direction of socialist market economy reform, the core issue is to properly handle the relationship between the government and the market, so that the market can play a decisive role in resource allocation and better play the role of the government. This is another major advance of our party in theory and practice.

-"Practically Unify Thought with the Spirit of the Third Plenary Session of the 18th CPC Central Committee" (November 12, 2013), Selected Important Documents Since the 18th CPC Central Committee (I), Central Literature Publishing House, 2014, p. 551.

Adhering to the direction of socialist market economy reform is not only the basic follow-up of economic system reform, but also an important support for comprehensively deepening reform. Making the market play a decisive role in resource allocation mainly involves economic system reform, but it will inevitably affect politics, culture, society, ecological civilization and party building and other fields. It is necessary to make all aspects of system reform advance in the direction of establishing a perfect socialist market economic system, and at the same time make all aspects of their own related links better adapt to the new requirements put forward by the development of socialist market economy.

The socialist market economic system established after 35 years of reform has been able to play the role of economic stabilizer to a considerable extent. Some things don’t need the government to do, and the market mechanism will automatically adjust. Some things don’t need to be done by the central government, and local governments will take the initiative to do the work. We insist on stable macro policies, flexible micro policies, simple administration and decentralization, give better play to the role of the market, and better reflect the division of labor between the central and local governments. We have stepped up efforts to transform the government’s job capacity, shifted the focus of our work to creating a fair competitive market environment, protecting the ecological environment, supporting innovation, etc., and enhanced the momentum and vitality of economic development.

-Speech at the Central Economic Work Conference (December 10, 2013)

Generally speaking, the market plays a decisive role. We should not blindly and absolutely say that the market plays a decisive role, but make the market play a decisive role in the allocation of resources and give full play to the role of the government. In some areas, such as national defense construction, the government plays a decisive role. Some strategic energy resources should be firmly controlled by the government, but they can be done through market mechanisms.

-Speech at the Fifth Meeting of the Central Financial and Economic Leading Group (March 14, 2014)

It is not only a major theoretical proposition, but also a major practical proposition to make the market play a decisive role in resource allocation and better play the role of the government. It is of great significance to scientifically understand this proposition and accurately grasp its connotation for comprehensively deepening the reform and promoting the healthy and orderly development of the socialist market economy. On the issue of market role and government role, we should talk about dialectics and two-point theory, make good use of both "invisible hand" and "visible hand", and strive to form a pattern in which market role and government role are organically unified, complementary, coordinated and promoted, so as to promote sustained and healthy economic and social development.

-Speech at the 15th collective study in the 18th the Political Bureau of the Central Committee (May 26th, 2014), People’s Daily, May 28th, 2014.

At the Third Plenary Session of the 18th CPC Central Committee, it was pointed out that the reform of the economic system is the key to comprehensively deepen the reform, and the core issue is to properly handle the relationship between the government and the market, so that the market can play a decisive role in the allocation of resources and better play the role of the government. Putting forward that the market plays a decisive role in the allocation of resources is a new breakthrough in our Party’s understanding of the law of Socialism with Chinese characteristics’s construction, a new achievement of Marxism in China, and a sign that the development of socialist market economy has entered a new stage.

-Speech at the 15th collective study in the 18th the Political Bureau of the Central Committee (May 26th, 2014), People’s Daily, May 28th, 2014.

Accurate positioning and grasping make the market play a decisive role in resource allocation and better play the role of the government, and we must correctly understand the relationship between the role of the market and the role of the government. The relationship between government and market is the core issue of China’s economic system reform. At the Third Plenary Session of the 18th CPC Central Committee, the market played a fundamental role in the allocation of resources and changed it to play a decisive role. Although there is only a difference of two words, it is a brand-new orientation for the role of the market. The two orientations of "decisive role" and "fundamental role" are connected, inherited and developed. Making the market play a decisive role in resource allocation and giving better play to the role of the government are organically unified, not mutually negative, and they cannot be separated and opposed. The decisive role of the market in resource allocation can neither be used to replace or even deny the government’s role, nor can it be used to replace or even deny the market’s decisive role in resource allocation.

-Speech at the 15th collective study in the 18th the Political Bureau of the Central Committee (May 26th, 2014), People’s Daily, May 28th, 2014.

Putting forward that the market plays a decisive role in resource allocation is actually implementing the problem orientation. After more than 20 years of practice, China’s socialist market economic system has been developing continuously, but there are still many problems, and there are still many drawbacks that constrain the vitality of market players and hinder the full play of the market and the law of value. If these problems are not solved well, it is difficult to form a perfect socialist market economic system, and it is also difficult to change the development mode and adjust the economic structure. We must adhere to the direction of socialist market economy reform, promote market-oriented reform in breadth and depth, reduce the direct allocation of resources by the government, reduce the direct intervention of the government in micro-economic activities, accelerate the construction of a unified, open and orderly market system, establish fair, open and transparent market rules, hand over economic activities that can be effectively regulated by the market mechanism to the market, and hand over things that the government should not be in charge of, so that the market can fully play its role in all areas that can play its role, and promote the allocation of resources to maximize benefits and optimize efficiency.

-Speech at the 15th collective study in the 18th the Political Bureau of the Central Committee (May 26th, 2014), People’s Daily, May 28th, 2014.

Scientific macro-control and effective government governance are the inherent requirements for giving full play to the advantages of the socialist market economic system. To give full play to the role of government, it is necessary to effectively transform government functions, deepen the reform of administrative system, innovate administrative management methods, improve the macro-control system, strengthen the supervision of market activities, strengthen and optimize public services, promote social fairness, justice and social stability, and promote common prosperity. Governments at all levels must strictly administer according to law, earnestly perform their duties, properly manage the affairs under their control, fully release the power, and resolutely overcome the dislocation, offside and absence of government functions.

-Speech at the 15th collective study in the 18th the Political Bureau of the Central Committee (May 26th, 2014), People’s Daily, May 28th, 2014.

It is an important feature of China’s socialist market economic system to uphold the leadership of the Party and give full play to the leading core role of the Party in commanding the overall situation and coordinating all parties. Over the past 30 years of reform and opening up, China’s economic and social development has achieved great achievements rarely seen in the world, and the living standards of our people have been greatly improved, which are inseparable from our firm adherence to the party’s leadership and giving full play to the role of party organizations at all levels and all party member. In our country, the strong leadership of the party is the fundamental guarantee for the government to play its role. In the process of comprehensively deepening the reform, we should uphold and develop our political advantages, lead and promote the reform with our political advantages, mobilize the enthusiasm of all parties, and promote the continuous improvement of the socialist market economic system and the better development of the socialist market economy.

-Speech at the 15th collective study in the 18th the Political Bureau of the Central Committee (May 26th, 2014), People’s Daily, May 28th, 2014.

When we deepen reform in an all-round way, we must stimulate the vitality contained in the market. Market vitality comes from people, especially entrepreneurs, and from entrepreneurship. To stimulate the vitality of the market, it is necessary to put the right to release in place, create a good environment, and formulate rules to make entrepreneurs useful. We emphasize the need to give full play to the role of the government, shift more from managers to service providers, serve enterprises and promote economic and social development.

-"Seeking Sustainable Development and Building Asia-Pacific Dreams Together" (November 9, 2014), People’s Daily, November 10, 2014.

The organic combination of the basic socialist system and the market economy, and the common development of the public-owned economy and the non-public-owned economy are great initiatives of our party to promote the liberation and development of social productive forces. At present, the number of non-public economic organizations has accounted for about 90% of the market players, and the GDP created has exceeded 60%. Facts have shown that as long as the Communist Party of China (CPC)’s leadership is adhered to, as long as public ownership is the mainstay and diversified ownership economies develop together, the superiority of the socialist system will not be weakened, but will continue to increase, and the foundation of our party’s governance will not be shaken, but will be more stable.

It is necessary to deepen the reform of the economic system around making the market play a decisive role in resource allocation and giving full play to the role of the government, accelerate the formation of institutional mechanisms and development methods that lead the new normal of economic development, accelerate the reform that is conducive to innovative development, coordinated development, green development, open development and shared development, accelerate the reform that is conducive to improving the efficiency of resource allocation and improving the quality and efficiency of development, accelerate the reform that is conducive to fully mobilizing the enthusiasm of all parties, and accelerate the reform that is conducive to the modernization of the national governance system and governance capacity.

China’s basic economic system is an important pillar of the Socialism with Chinese characteristics system and the foundation of the socialist market economic system. The dominant position of public ownership cannot be shaken, and the leading role of the state-owned economy cannot be shaken. This is an institutional guarantee to ensure that the people of all ethnic groups in China share the fruits of development, and it is also an important guarantee to consolidate the party’s ruling position and adhere to China’s socialist system.

-"Speech at the 28th Collective Study in the 18th the Political Bureau of the Central Committee" (November 23, 2015)

Developing market economy under socialist conditions is a great pioneering work of our party. A key factor for the great success of China’s economic development is that we have brought into play the advantages of both the market economy and the socialist system. We are developing the market economy on the premise of the Communist Party of China (CPC)’s leadership and the socialist system, and we must never forget the attribute "socialism". The reason why it is a socialist market economy is to uphold the superiority of our system and effectively guard against the disadvantages of the capitalist market economy. We must adhere to dialectics and two-point theory, continue to work hard on the combination of the basic socialist system and the market economy, give full play to the advantages of both aspects, and strive to solve this worldwide economic problem in practice.

-"Speech at the 28th Collective Study in the 18th the Political Bureau of the Central Committee" (November 23, 2015)

Accelerate the reform of the fiscal and taxation system. It is necessary to grasp key issues such as dividing the central and local powers and expenditure responsibilities, improving the local tax system, enhancing local development capabilities, and reducing the burden on enterprises, and accelerate the reform of the fiscal and taxation system. It is necessary to promptly formulate a plan for dividing the central and local powers and expenditure responsibilities, moderately strengthen the central powers and expenditure responsibilities, hand over some affairs that are suitable for local governments to local governments, and reduce matters that the central and local responsibilities overlap and jointly manage. According to the principle of tax sharing, the taxes suitable for local income should be allocated to local governments, and the tax rate can be appropriately decentralized to local governments. It is necessary to speed up the introduction of environmental protection tax and promote the reform of resource tax.

-"Doing a Good Job in Current Economic Work around Implementing the Spirit of the Fifth Plenary Session of the 18th CPC Central Committee" (December 18, 2015)

It is necessary to form a stock market with complete financing function, solid basic system, effective market supervision and full protection of investors’ legitimate rights and interests as soon as possible. It is necessary to study and put forward the reform plan of the financial supervision system, focus on coordinating the supervision system of important financial institutions, financial holding companies and important financial infrastructure, and strengthen comprehensive supervision and functional supervision. There are different approaches to what kind of financial supervision system to implement in the world. We should proceed from China’s national conditions, especially adhere to the problem orientation, determine our thinking quickly, and don’t argue and delay for a long time. It is necessary to accelerate the reform of the banking system, deepen the reform of state-owned commercial banks, optimize the shareholding structure and improve corporate governance. It is necessary to expand private capital into the banking industry, develop a number of commercial banks controlled by private capital, lower the entry threshold, and realize the normalization of the establishment of private banks. It is necessary to accelerate the development of green finance and set up a green development fund. It is necessary to take advantage of the opportunity of RMB entering the basket, accelerate the reform and opening up of the financial industry, and steadily promote RMB to become an international reserve currency.

-"Doing a Good Job in Current Economic Work around Implementing the Spirit of the Fifth Plenary Session of the 18th CPC Central Committee" (December 18, 2015)

Making the market play a decisive role in resource allocation is the main line of deepening economic system reform. The Third Plenary Session of the 18th CPC Central Committee put forward that the market should play a decisive role in the allocation of resources and give full play to the role of the government. I talked about both aspects, but I made it clear in the explanation of the plenary session that the focus of the reform is to solve the problems of imperfect market system, excessive government intervention and inadequate supervision. To give full play to the role of the government is not to give full play to the role of the government, but to manage those things that the market can’t or can’t manage well on the premise of ensuring that the market plays a decisive role.

-"Doing a Good Job in Current Economic Work around Implementing the Spirit of the Fifth Plenary Session of the 18th CPC Central Committee" (December 18, 2015)

Our party’s view on adhering to the basic economic system is clear and consistent, and it is constantly deepening and has never wavered. The Communist Party of China (CPC) and party constitution have stated this point, which will not change and cannot be changed.

I reiterate here that the position and role of the non-public sector of the economy in China’s economic and social development have not changed. Our principles and policies of unswervingly encouraging, supporting and guiding the development of the non-public sector of the economy have not changed. Our principles and policies of creating a good environment and providing more opportunities for the development of the non-public sector of the economy have not changed.

-"Unswervingly adhere to China’s basic economic system and promote the healthy development of various ownership economies" (March 4, 2016), People’s Daily, March 9, 2016.

Our emphasis on consolidating and developing the public sector of the economy is not antagonistic to encouraging, supporting and guiding the development of the non-public sector of the economy, but organically unified. Our country is so big and has such a large population, and it is in the primary stage of socialism and will be in it for a long time. To promote economic and social development, it is necessary for all parties in Qi Xin to work together, and everyone will gather firewood. Public-owned economy and non-public-owned economy should complement each other, rather than mutually exclusive and offset each other.

-"Unswervingly adhere to China’s basic economic system and promote the healthy development of various ownership economies" (March 4, 2016), People’s Daily, March 9, 2016.

All localities and departments should proceed from reality, refine and quantify policies and measures, formulate relevant supporting measures, and promote the implementation of various policies, so that private enterprises can truly enhance their sense of gain from policies.

At present, we should focus on solving the following problems. First, efforts should be made to solve the financing difficulties of small and medium-sized enterprises, improve the financial system, and provide reliable, efficient and convenient services for financing of small and medium-sized enterprises. Second, efforts should be made to liberalize market access. All industries and fields that are not explicitly prohibited by laws and regulations should be encouraged to enter, and all fields that the Chinese government has opened to foreign investment or promised to open should be opened to domestic private capital. Third, efforts should be made to speed up the construction of the public service system, support the establishment of a common technical service platform for private enterprises, actively develop the technology market, and provide technical support and professional services for independent innovation of private enterprises. Fourth, efforts should be made to guide private enterprises to make use of market portfolio private capital, carry out cross-regional and cross-industry mergers and acquisitions, and cultivate a number of large enterprise groups with outstanding characteristics and strong market competitiveness. Fifth, it is necessary to further clean up and streamline the administrative examination and approval items and enterprise-related fees involving private investment management, standardize the behavior of intermediate links and intermediary organizations, reduce the burden on enterprises and reduce their costs.

-"Unswervingly adhere to China’s basic economic system and promote the healthy development of various ownership economies" (March 4, 2016), People’s Daily, March 9, 2016.

To deepen the reform of economic system, the core is to properly handle the relationship between the government and the market, so that the market can play a decisive role in the allocation of resources and better play the role of the government. This requires dialectics and two-point theory, and both "invisible hand" and "visible hand" should be used well. The key is to speed up the transformation of government functions. The power given to the market and society must be fully put in place, and the affairs managed by the government must be well managed and properly managed, and the phenomenon of dislocation, offside and absence of government functions must be resolutely reversed. It is necessary to deepen the reform of the administrative examination and approval system, promote decentralization, deepen the management of power list and responsibility list, and at the same time strengthen supervision after the event.

-"Speech at the Deliberation of the Shanghai Delegation to the Fourth Session of the 12th National People’s Congress" (March 5, 2016)

State-owned enterprises must not only do well, but also do well. Relevant departments in all regions and the vast number of state-owned enterprises should follow the decision-making arrangements of the CPC Central Committee on promoting the reform and development of state-owned enterprises, adapt to the development and changes of the domestic and international economic situation, adhere to the policy of maintaining and increasing the value of state-owned assets, improving the competitiveness of the state-owned economy and amplifying the functions of state-owned capital, promote the deepening reform of state-owned enterprises, improve their management level, strengthen the supervision of state-owned assets, and unswervingly make state-owned enterprises stronger, better and bigger.

-Speech at the National Conference on Party Building in State-owned Enterprises (October 10, 2016)

The role of the market and the role of the government are complementary, mutually reinforcing and complementary. We must persist in making the market play a decisive role in resource allocation, improve the market mechanism, break down industry monopoly, entry barriers and local protection, enhance enterprises’ ability to respond and adjust to changes in market demand, and improve the efficiency and competitiveness of enterprise resource allocation. Giving full play to the role of the government is not simply issuing administrative orders. On the basis of respecting the laws of the market, we should stimulate market vitality with reform, guide market expectations with policies, clarify investment direction with planning, and regulate market behavior with the rule of law.

Learn from the past and learn from the past, follow the general secretary to learn history, walk into a museum, and seek the roots of Chinese civilization for 5 thousand years

Learn from the past and learn from the past, follow the general secretary to learn history, walk into a museum, and seek the roots of Chinese civilization for 5 thousand years

  Yuncheng, located at the southernmost tip of Shanxi, has a long history and a thick context. On the afternoon of May 16th, General Secretary of the Supreme Leader visited Yuncheng Museum to learn more about the origin of human beings and the early historical development of Chinese civilization. He emphasized that there are many precious cultural relics and even "national treasures" in the museum, which have proved the history of human beings for one million years, the history of culture for 10,000 years and the history of civilization for more than 5,000 years in China. It is necessary to carry out the project of tracing the source of Chinese civilization in depth and lead the research on the history of China civilization in depth.

  Learn from the past and learn history with the general secretary. Today, I walked into Yuncheng Museum to see that Chinese civilization has a long history of 5,000 years.

  Click to listen to the audio version of Learn from the Past.

  The birthplace of Chinese civilization

  The surging Yellow River, flowing through the ages, forms a zigzag "several" bend on the Chinese territory. Yuncheng, Shanxi Province, is a fertile land that has been brought into the arms of the Yellow River. Surrounded by mountains and rivers, the climate is mild and the rainfall is abundant. In ancient times, it was a treasure house favored by our ancestors.

  Yuncheng, called Hedong in ancient times, is one of the cradles of Chinese civilization.

  Here, about 45 million years ago, the "century apes" fossils were discovered, which pushed forward the origin of higher primates for 10 million years.

  Here, the earliest evidence that humans used fire 2.43 million years ago was found. The burnt bones and the antlers with cuts shone with the light of ancient human wisdom and civilization.

  Here, Yao Shunyu and China’s first slave society — — The Xia Dynasty established the capital successively, which gave birth to the earliest farming civilization in China.

  Thousands of years of civilization have left rich cultural relics in Yuncheng. In Yuncheng Museum, one exhibit tells the historical vicissitudes of Chinese ancestral culture for future generations.

  Culture has roots and civilization is active.

  General Secretary of the Supreme Leader stressed that "it is necessary to deeply understand the development history of Chinese civilization for more than 5,000 years, deepen the research on the history of China civilization, and promote the whole party and society to enhance historical consciousness and strengthen cultural self-confidence."

  For the world to understand China, China must first understand itself.

  The spring and autumn of dabao salt in the country

  "Guo, Hedong Yanchi also."

  Hedong Salt Pond, located in the hinterland of the inland, is a precious gift from nature. Since ancient times, people have lived around the salt pond and lived on it.

  Yuncheng is famous for its salt pond and salt transportation.

  Hedong salt pond is the earliest salt pond in the world, with a mining history of more than 4600 years. Salt Lake, as an important strategic resource, is the common goal of all tribes in the ancient Central Plains of China. From the battle of the Yellow Emperor Chiyou in ancient legends to the historical records of emperors such as Zhou Muwang, Emperor Hancheng, Emperor Hanzhang, Emperor Taizong and Kangxi, Hedong Salt Pond was regarded as "the treasure of the country" by successive dynasties.

  Hedong Salt Lake has been related to the national economic lifeline and the source of finance and taxation since ancient times. Especially during the Tang Daizong calendar year, the annual tax revenue of Hedong Salt Lake accounted for about a quarter of the national salt revenue and an eighth of the national fiscal revenue.

  Pool salt culture plays an important role in the development history of Chinese civilization, which nourishes the Millennium civilization and makes historic contributions to the prosperity, economic development and social progress of the Chinese nation.

  The genetic code of China Road.

  "When I visit a place, I will take time to go to the museum and have a look. The purpose is to better understand the historical and cultural evolution of a place." General Secretary of the Supreme Leader once explained why he walked into the museum again and again.

  A museum is a big school.

  Xinjiang Uygur Autonomous Region Museum, Hebei Chengde Museum, Guangxi National Museum, Jiangsu Nantong Museum, Shaanxi Xi ‘an Museum … … Follow the footsteps of the general secretary, and see the Millennium from square inch to square inch.

  Museum is an important place to protect and inherit human civilization, and a bridge connecting the past, the present and the future.

Learn from the past and learn from the past, follow the general secretary to learn history, walk into a museum, and seek the roots of Chinese civilization for 5 thousand years

  Chinese culture, which has been uninterrupted for more than 5,000 years, is the root and soul of the Chinese nation.

  General Secretary of the Supreme Leader once said, if there is no Chinese civilization for 5,000 years, where can there be any China characteristics? If it weren’t for the characteristics of China, how could we have such a successful Socialism with Chinese characteristics road today?

  In October, 2022, General Secretary of the Supreme Leader profoundly pointed out when he participated in the discussion of the 20th Guangxi delegation of the Party: "China embarked on this road, which is inseparable from China culture. The Socialism with Chinese characteristics road we are taking, its inherent genetic code is here, and there is the gene of Chinese excellent traditional culture. "

  At the beginning of this year, the general secretary emphasized that "Chinese modernization is deeply rooted in Chinese excellent traditional culture" and "it is a brand-new form of human civilization".

  With the protection and inheritance, innovation and development, Chinese excellent traditional culture is constantly blooming with new glory of the times, providing correct spiritual guidance and strong spiritual motivation for the progress of human civilization.

Expert interview: Old viruses frequently change their faces. Traditional antivirus is in a hurry.

  New anti-virus technology for active defense


  The opening and closing ceremonies of the Beijing Olympic Games and Paralympics are the focus of the world’s attention. Assuming that the computer information of the general director Zhang Yimou is stolen and attacked by hackers, not only will the Olympic plan be leaked, but even the opening and closing ceremonies will not be able to proceed normally …


  In the US presidential election, Obama was most worried about the theft of his core computer and the attack on the network. He summed up his victory and the victory of the network.


  Network security has a bearing on the people’s livelihood. Faced with more than 1,000 new viruses appearing every hour in the world, traditional anti-virus software is increasingly lagging behind, and active anti-virus technology emerges as the times require.


  According to the 2008 National Survey Report on Information Network Security and Computer Virus Epidemic released by the Ministry of Public Security recently, among the types of network security incidents, computer viruses, worms and Trojan horses are still very prominent, accounting for 72%. Another new security risk "passive leak" is eroding the computer network.



  Liu Xu, a famous anti-virus expert and leader of the research group of "Real-time protection technology based on independent analysis and judgment of program behavior" of the National 863 Program.


  What causes the increase of "passive disclosure", and how can users avoid being victims of Trojan virus or targets of "spy" programs? The reporter interviewed Liu Xu, a famous anti-virus expert and the leader of the research group of "Real-time protection technology based on autonomous analysis and judgment of program behavior" of the National 863 Program.


  Hackers wholesale a "broiler" in 0.1 yuan.


  Zombies attack other people’s computers in groups


  Users unconsciously passively leak secrets.


  Liu Xu said that in the industry, computers controlled by hackers are called "broilers", and any computer may become a "broiler". For hackers, "broiler" has no secrets, and all information files can be easily adjusted. Such a "broiler" is now sold online only in 0.1 yuan. Because of its low price, "broiler" is generally sold in tens of thousands of wholesale units. Recently, the use of "Microsoft black screen genuine verification" to spread the variant gray pigeon new virus is to make the user’s computer a remotely controlled "broiler".


  There are even more terrible "zombies", that is, computers controlled by "zombie" viruses. These computers are aggressive, and the "zombie" computers controlled by hackers form a network, which will attack other people’s computers and important websites. "Zombies" are mostly overseas hacker networks, mainly stealing trade secrets and threatening the security of national information networks.


  Liu Xu said that the purpose of writing and making viruses has changed from "harming others without benefiting themselves" to profit-seeking attacks, such as stealing information; The computer poisoning rate also rose from 73% in 2001 to 91.47% last year. At present, viruses have the latest features such as instrumentalization and automatic generation, and at the same time, they have the characteristics of concealment, anti-killing and pertinence. Unknown viruses and new viruses make users hard to prevent. In the past two years, "online thieves", "panda burning incense", "dove", "QQ Trojan" and "zombie Trojan" have invaded users’ computers and stolen password accounts, personal privacy, business secrets, network property and even state secrets, which are typical examples. If we don’t take precautions against these Trojans and spy viruses, it will easily cause users to passively disclose information unconsciously.


  Traditional antivirus only looks for a piece of program code.


  There is nothing I can do about makeup makeovers.


  Almost all computers are equipped with anti-virus software, but why are users repeatedly attacked and even passively leaked information? Liu Xu said that the traditional anti-virus software was an effective tool in the past when the number of viruses was small and the spread speed was not fast. However, today, with the wide application of the Internet and the subversive changes in the global virus characteristics, it is obviously inadequate.


  Liu Xu analyzed the principle of traditional antivirus software. For example, traditional anti-virus software kills viruses, just like low-level security guards catch thieves, relying entirely on local characteristics. If you catch a thief in red today, you think that everyone in red is a thief, and if you catch a thief in yellow tomorrow, you think that the thief in yellow is also a thief. When a virus is found, one or several program codes are found, which is the virus feature code. Once similar or identical codes are found, it is considered as a virus. Traditional anti-virus software adopts the eigenvalue scanning technology: the idea of "virus appearance ―― user submission ―― manual analysis by manufacturers ―― software upgrade". The prevention of virus always lags behind the emergence of virus, and generally it can only kill the virus found by manufacturers, but it is helpless for new viruses or those that have undergone "cosmetic" transformation.


  At present, viruses have been automated and industrialized, and anti-virus manufacturers are still adopting backward ideas of manual analysis, which is bound to fail to prevent unknown viruses and new viruses. Realizing the transformation of anti-virus technology from passive anti-virus after the event to active defense is not only the common topic and new competition focus of the global anti-virus industry, but also the urgent demand of computer users.


  Micro-point active defense software of 863 project


  Ensure the network security of the opening and closing ceremonies of the Olympic Games


  Liu Xu said that at present, most anti-virus software claims to have active defense function, but active defense is a real-time protection technology based on independent analysis and judgment of program behavior, which must have three basic characteristics: independent identification of unknown viruses and new viruses, clear reporting and automatic removal. This is the touchstone to distinguish between true and false active defense, especially "clear reporting" of unknown viruses and new viruses, which most anti-virus software can’t do.


  In addition, some traditional anti-virus software does not explicitly report whether there is a virus, but uses some languages that ordinary users can’t read, such as: "A program is setting a global hook for your computer, is it allowed?" and "A program is loading a driver, please choose", so that users can judge for themselves, and it is difficult for non-computer professionals to choose.


  The national 863 project-micro-point active defense software is the first active defense software in the world. By using the simulated anti-virus expert and its virus determination mechanism, it has achieved the breakthrough of five core technologies, such as "dynamic simulation of anti-virus expert system, automatic and accurate determination of new viruses, simultaneous monitoring of program behavior, automatic extraction of feature values to achieve multiple protections, and visual display of monitoring information". After nearly a million kinds of viruses have been tested, the effective rate of preventing and killing unknown viruses and new viruses is over 99%.


  Since the opening and closing ceremonies of the Beijing Olympic Games, the operation center adopted the national 863 project-micro-point active defense software, which successfully prevented the attacks and intrusions of hackers and various new and old viruses, and the network information system of the operation center never leaked information, which indicates that China’s anti-virus technology has successfully withstood the major test of the Beijing Olympic Games and Paralympic Games.


  Don’t go to unhealthy websites to avoid being poisoned.


  Rejecting unknown mail is best for special plane.


  Copying files between computers without USB flash drive


  Liu Xu pointed out that users should have a conscious awareness of information security. First of all, we should develop good online habits. Some unhealthy websites are often an important reason for users’ virus infection.


  Secondly, it is not only a way to infect and spread the virus, but also an important reason for the passive disclosure of information caused by virus attacks and hacker intrusions. In practical work, especially for users with high requirements for information security, we should try our best to put an end to copying files back and forth between different users with USB flash drives, and we should also strengthen the protection of users’ own mail security and refuse unknown mail. At the same time, the conditions should be dedicated to the special plane.


  Third, adopt safe and reliable anti-virus tools. More and more examples have proved that anti-virus software itself is vulnerable to attack. Therefore, we should not only use non-genuine software with caution, but also carefully choose anti-virus tools. It is a reliable choice to adopt anti-virus tools with real active defense technology.

Can the seven "scenario clouds" of Unicom Cloud enable users to realize the freedom of cloud computing?

Not long ago, Unicom Cloud "went out of the circle" and deeply cultivated the legal profession, and "Tianfu Central Legal Cloud" was officially released. Tianfu Central Legal Cloud relies on Unicom’s cloud capabilities, and integrates new generation information technologies such as 5G, big data, Internet of Things, artificial intelligence, blockchain and security capabilities to create a secure, credible, cloud-integrated, self-controllable, cloudy, collaborative and customized digital China legal service intelligent cloud.

In fact, government and enterprise organizations from government, medical care, manufacturing, education, finance and other industries have chosen Unicom Cloud "going to the cloud" one after another, and used different "scenario clouds" of Unicom Cloud to meet the needs in various business scenarios such as municipal services, epidemic prevention and control, medical image storage, smart city security, smart travel, building supervision and so on.

The competition in the cloud computing market has always been fierce. Why can Unicom Cloud stand out from the crowd of cloudy manufacturers and become the first choice for government and enterprises? What is the "scene cloud" of Unicom Cloud and what are its advantages?

The development of cloud computing enters the deep water period, and the acceleration of Unicom cloud runs out.

In recent years, the development of cloud computing market in China has entered a deep-water period. The whole industry has gradually shifted from choosing Internet and IT enterprises to traditional government and enterprise organizations, and the market structure has begun to change. The cloud computing brand of operators represented by Unicom Cloud is growing like a bamboo, and gradually gained a place in the cloud computing market.

Why did this market change happen? The main reasons come from two aspects:

First, Unicom Cloud has continuously cultivated its internal strength and given the market full confidence with its excellent strength. From "Wo Yun" to "Unicom Cloud" with brand rejuvenation, China Unicom has forged an integrated cloud computing product integrating network, hardware, IaaS, PaaS, SaaS, terminals and services after 13 years of tempering.

Nowadays, Unicom Cloud has not only grown into a unified computing base to undertake China Unicom’s big computing business, but also a full-stack capability cloud that can support the digital transformation of all walks of life, so Unicom Cloud has become an important pole in the cloud computing service market in China.

Second, the needs of traditional government and enterprise users to access the cloud are different. They no longer aim at low cost, but pay more attention to how the overall solution of the cloud empowers traditional applications and enhances the degree of intelligence and digitalization.

Based on this, the competition of cloud vendors has also moved from the simple IaaS infrastructure level to the comprehensive comprehensive cloud platform service capability of IaaS+PaaS+SaaS, and the competition behind it is the ability to solve practical problems in diversified business scenarios. On the one hand, it tests whether cloud vendors have complete PaaS functions such as cloud native, big data, artificial intelligence, Internet of Things, etc. On the other hand, it also requires cloud vendors to have fast and perfect solution service capabilities and implementation delivery ecology.

Today, Unicom Cloud can provide more than 280 IaaS and PaaS products, support billions of IoT connections, provide more than 40 artificial intelligence atomic capabilities, 8 blockchain universal service components, and aPaaS components support more than 160 self-developed applications to meet the general needs of various customers.

Not only that, Unicom Cloud also took the lead in proposing a "scenario cloud" in the industry, which encapsulates and uniformly outputs cloud components and cloud capabilities that combine innovative technologies such as 5G, artificial intelligence, big data, Internet of Things, blockchain, trusted security, etc., and forms a number of digitally competitive and integrated cloud solutions, aiming to provide a landing solution for the segmentation scenario needs of traditional government and enterprise users in digital transformation. For this reason, the "scene cloud" has also become the starting point for China Unicom’s rapid development and landing industry.

Seven scenario clouds, allowing users to realize the freedom of cloud computing.

According to Pang Yufeng, director of the product technology department of the operation platform of Unicom’s Digital Cloud Computing Division, the release of the "scenario cloud" product not only integrates China Unicom’s professional capabilities in cloud infrastructure, big data, Internet of Things, AI, blockchain, etc., but also combines the needs of customers in various industries to extract various general scenario capabilities. It is not only suitable for a certain industry, but also from a more subdivided business scenario, which is more grounded in meeting customer needs.

Intelligent video cloud can fully empower multi-scene video applications from three levels: "cloud network intelligence technology integration, product platformization and application scenario", and provide a unified and open interface to meet the needs of multi-scene video surveillance applications. First of all, intelligent video cloud can support public cloud, central cloud and hybrid cloud deployment, and quickly integrate AI atomic capabilities; It can also be deployed flexibly in a modular and modular manner according to the video surveillance requirements of smart city construction. Secondly, support security mechanisms such as HTTPs security protocol and AES video encryption to ensure data security; It also supports the flexible expansion of resources and meets the requirements of massive surveillance video access and high concurrent processing. At the same time, it can provide intelligent detection, analysis and early warning services by adapting to intelligent AI applications such as personnel intrusion, crowd statistics and mask compliance.

Therefore, the intelligent video cloud can well meet the requirements of "seeing, storing, managing, controlling and maintaining" of video surveillance, so as to promote the construction and networking application of public safety video surveillance, and explore the implementation of off-site supervision characterized by remote monitoring supervision and early warning prevention and control; Coordinate road video monitoring, community monitoring and other systems, perceive urban elements such as traffic trips, ecological environment and urban scenes in real time, promote the construction of "Zhi ‘an Community" and "Zhi ‘an Unit", and innovate the intelligent social security prevention and control system.

As Pang Yufeng said, "scene cloud" is like a cloud computing "supermarket". Customers can freely buy and mix whatever they want. The technology behind the scene cloud solution can be "loose and coupled", which can not only meet the individual business needs of industry customers, but also provide a package of overall solutions, so that users can fully enjoy the freedom of cloud computing.

Thick accumulation and thin hair, the scene cloud empowers thousands of industries.

With the deepening of industrial digitalization and the continuous enrichment of application scenarios, the launch of Unicom cloud "scenario cloud" is just the right time, and a large number of customer cases have fully verified its market value. At present, Unicom Cloud has served more than 20 ministries and more than 300 large enterprises, including network services, cloud, big data applications and security services.

According to the latest report of IDC, in the third quarter of 2021, the market share and revenue growth rate of Unicom Cloud Public Cloud ranked first among all manufacturers, providing strong support for the digital construction of eight vertical industries, including government affairs, medical care, industry and education.
