Big soda, drink big kiln – this summer’s most popular big kiln drink investment is in progress…

The beginning of summer in 2022 is approaching, and the temperature continues to rise. This is the golden stage for beverage sales, and it is also an important time for dealers to choose products and brands. For dealers, the correct choice determines the annual income. Therefore, when the peak season "soda war" is about to start, which brand to choose has become the top priority.

But it is undeniable that no matter how the market changes, following the popular brands will definitely not suffer. Nowadays, the "big soda" category is very popular in the market. As the pioneer of the "big soda" category, Dayao Beverage has extremely high brand influence, good market performance, and signed the screen hero Wu Jing as the brand spokesperson in early 2022, with broad prospects. Therefore, whether it is looking at the intensive farming ability and track position, or looking at the company’s planning and competitiveness from a distance, Dayao Beverage is the best choice for major distributors.

Eight core production bases ensure product quality and high profits for distributors

With the expansion of the market territory, Dayao is also investing heavily in building its own production base and gradually realizing a wider production and logistics layout. At present, it has 8 core modern production bases in the four major regions of Northwest, North China, Northeast and East China. The core origin layout can not only ensure product quality, but also achieve low transportation costs, sufficient and timely supply, minimize costs, and then release huge profit margins to dealers.

The "Big Soda" track is hot, and Dayao drinks have become the category benchmark

As a leader in the domestic "big soda" category, in October 2021, Dayao Beverages joined hands with "Hua and Hua" to create the brand super discourse of "big soda, drink big kiln", and took "big soda" as the brand strategic positioning, continued to take "big soda and aerated beverages" as the core characteristics, and played the marginal effect of the brand.

In addition to strengthening its unique advantages in "big soda", Big Kiln Beverage has also created a category benchmark for large glass bottles of soda, attracting brands to imitate. According to the National Bureau of Statistics, the cumulative output of carbonated beverages (soda) in China reached 19.964 million tons from January to October 2021, an increase of 20.8% year-on-year. From the perspective of explosive categories, its core mainstream products are large-size soda with more than 500 ml. It can be seen from the "Domestic Soda Evaluation" activity initiated by "Food Industry Headlines" that 8 of the 21 soda brands participating in the evaluation have launched large-size soda products, winning with large capacity, accounting for one-third. It can be seen that "big soda" has become a trend.

all-roundMarketingHelp dealers win the end point

In today’s increasingly fierce competition, the success of an enterprise is definitely the success of its organizational system. Dayao Beverage has been deeply involved in the industry for decades, and its popular taste, personalized product image, extensive catering distribution channels and good agency services have always been the objects of competition among major distributors. However, for the existing market achievements, Dayao Beverage does not stop there, but continues to make efforts in brand marketing methods.

In January 2022, Dayao signed a powerful movie star Wu Jing as the brand spokesperson, and the whole network was boiling for a while. Wu Jing’s "positive energy representative" attribute was quickly grafted onto the Dayao brand, solidifying the national temperament of Dayao and enhancing the comprehensive potential of the brand. And its endorsement advertisements will also be simultaneously landed on CCTV, Moments and all media platforms such as major market business circles, elevators, and transportation across the country during the peak sales season, dedicated to participating in every scene of consumer life and work, and rooting the brand concept in the hearts of every audience.

In the national sales end point, the end point lighting project of the big kiln this year has been fully blossomed, and large-scale implantation of the big kiln brand super sign "color bar lace", brand slogan "big soda, drink big kiln", brand spokesperson Wu Jing image, and catering end point sales slogan "don’t drink, drink big kiln", so that big kiln drinks are everywhere and deeply rooted in the hearts of the people.

Big Kiln Beverages continues to innovate and enrich product categories, helping distributors capture the peak season market

In order to inherit the classics, new changes are required. In the context of consumption upgrades, the category of the beverage industry is constantly differentiated and reconstructed, and the products are rapidly iterated and upgraded. On the basis of the original star single products, Dayao Guests and Dayao Chengnuo, Dayao Beverages has successively launched more flavors and specifications of carbonated beverages, such as 520ml glass bottles, Dayao Liai, 275ml small kiln fruit steam, 1.314L Dayao Guests, Dayao Yinnuo, Dayao Lixiang, and many independent innovation products such as innovative carbonated products based on zero sugar series, successfully built a diversified product matrix, helping distributors seize the beverage peak season market. Nowadays, Dayao Beverage has fully deployed innovative product lines such as carbonated drinks, fruit and vegetable juice drinks, vegetable protein drinks, and 0 sugar. It is believed that Dayao Beverage will bring greater surprises to the industry and greater dividends to distributors in 2022.

After years of development, Dayao Beverage has achieved great success. At present, the products have covered nearly one million end point outlets in 35 provinces, municipalities, autonomous regions and municipalities directly under the Central Government, and are exported to Mongolia. The market share is high and the customer source is stable. I believe that more partners will join Dayao in the future and create the era of domestic soda together.

For distributors who really want to join, Dayao will adopt a "four-dimensional evaluation system", that is, four dimensions of ability base, soft factors, industry status, and cooperation willingness to comprehensively select them. For distributors who have reached a cooperation, Dayao will carry out 1v1 face-to-face auxiliary management, send city managers and regional managers to the regional market, and effectively analyze and solve the actual problems encountered in market expansion such as channel development, market distribution, and product sales.

At this stage, Dayao Beverages is attracting investment. Interested beverage dealers can contact them through the official website of Dayao for details.

  Original title: Please, it’s cool to have your own gym, okay?

  Author: Huahua

  Everybody, this is Huahua ~

  Some time ago, Huahua was blocked by the little brother in the gym when she got off work. She took me for half an hour and introduced me. Looking at the increasingly dark day, Huahua had only one thought in her heart: "Leave me alone!"!

  Although sedentary people in offices like Huahua do have a lot of physical problems and want to exercise, it’s dark every day when they come home from work, and there is no energy to go to class, not to mention the epidemic situation. Maybe one day the gym will be closed and thousands of dollars will be wasted. My little heart can’t stand it.

  However, summer is coming, and the demand for fitness is on the agenda again. In addition, I have been closed at home recently, so I really don’t have the conditions to go out for exercise and spend a lot of time thinking about it. In this case, I might as well exercise at home. So I did my homework and quickly collected some good things for home fitness to share with you! Taking into account the different personal fitness needs and inputs, Huahua has chosen this and divided everyone into three categories from the input cost. Babies can choose according to their own needs.

  As we all know, there are many fitness bloggers on various platforms now, and Huahua usually likes to watch this kind of courses (watched+collected = done). This time, I carefully selected three favorite bloggers to share with you, which is very suitable for babies who want to keep fit but are not sure whether they can stick to it and plan to try it first ~

  one

  growwithjo

  She is the first fitness blogger that Huahua paid attention to. Many people in bilibili carried her videos and made a collection. You can find them by searching for keywords.

  There are several series of her videos, including brisk walking aerobics, boxing, happy dancing and so on. The length of the videos ranges from 5 minutes to one hour. Walking aerobics series is more suitable for beginners. It is no problem for Huahua to follow her series for 20 minutes at the beginning, but now it has advanced to the happy dance series, which is very expensive ~

  GolfyDance

  This teacher has his own account in bilibili, mainly to update some KPOP* fitness dances. The choreography is inspired by the original choreography and MV*, so his videos will contain some original dance movements. It is very friendly to all the babies who like KPOP but have no dance foundation. (KPOP: Korean pop music, MV: music short film)

  When Huahua first knew him, she practiced his video at home all night. That is to say, is it possible to occupy a place in random dance in the future?

cr:bilibili@GolfyDance

  Mark Marshall

  Mark has accounts in Xiaohongshu and bilibili, which is really amazing. His videos are mainly a series of sweaty and fat-burning dances, one song and one video. After dancing three videos, you will sweat profusely and mobilize all your muscles.

  The most interesting thing is Mark’s explanation. Every time you dance, you not only exercise your body muscles but also your facial muscles. After sweating, you feel better. Every day, the workers who jump and jump are not emo (in a bad mood). Hahahaha ~

  For the baby who doesn’t like aerobics and doesn’t want to make too much investment, Huahua has also selected several "wild" equipment for everyone. It is no exaggeration to say that you can help you practice your whole body at home within 200!

  Decathlon elastic rope

  Reference price: 29.9

Cr: Little Red Book @ Mark Fintess Marshall

  Elastic rope is the product with the least investment in this series, but don’t underestimate it. Such a rope can help us practice all the muscles.

Cr: xiaohongshu @miso

  Huahua chose this one of Decathlon because it is made of natural ecological latex, which is non-toxic and tasteless, does not harm health, and the seamless sewing technology will not harm the skin during stretching. Its thickening design does not break after 12000 fatigue tensile tests, so it is more assured when exercising.

  Moreover, the elasticity is super-large, and it does not deform after three times stretching. After 200 hours (450 watts) of UV (ultraviolet) anti-aging test, there is no need to worry about aging adhesion and aging fracture after using it for a while, even if it is as strong as cattle, it is very reassuring ~

  There are 6 kinds of elastic belt with different resistance values to choose from, which are suitable for the exercise needs of different groups of people. It’s so small, it’s easy to carry, and you can take it out at any time to stretch yourself when you are tired of sitting at the station ~

  Yottoy yoga mat

  Reference price: 69

Cr: Little Red Book @VVicky

  Yoga mat is an essential entry-level product for many fitness whites. Huahua bought a yoga mat blindly when she first bought it. She just fished out a particularly cheap one and took it home to practice. As a result, she almost didn’t give it away when she opened it, and she moved it without making two action mats. After several uses, many places cracked, and so did I.

Cr: Taobao official

  This time, I learned the previous lesson. The Yottoy’s yoga mat is made of TPE’s environmentally-friendly raw materials, which has no taste and improves the anti-slip performance. This is not enough. It also has a double-sided anti-slip texture, so you don’t have to worry too much about slipping when sweating on it during exercise. In addition, there is a posture line design for your reference when doing yoga, and the color of Mo Landi makes this yoga mat look even higher!

Cr: Little Red Book @ Li Changle.

  The widened and thickened design allows Huahua to "roll" out without having to side. . . Even if you jump rope on it in the middle of the night, you won’t knock on my door downstairs. Moreover, the resilience is still very good, and the knee will return to its original shape after pressing a nest on it for a few seconds. Buying this one is worth buying 10 pieces with 9.9 packages. You don’t want me to use it forever, do you?

  KEEP intelligent skipping rope SR1

  Reference price: 149

Cr: Little Red Book @ Live in the Present, Not Afraid of the Future

  Everyone can jump rope, right? It is not only a relatively simple way to lose weight, but also can exercise our respiratory system and cardiovascular system. The fat burning efficiency is very high, and the baby who wants to lose weight as a whole must pick it!

  KEEP’s skipping rope can be linked with its APP, and there are many interesting skipping lessons to practice. When you open the APP during exercise, you can start monitoring the frequency and data in real time, and you can store it offline even if your mobile phone is not around, so you won’t miss every exercise punch. Moreover, it can accommodate up to ten people to share data, and you can let go of your hands and feet and have a "war" with your family!

Cr: xiaohongshu @hi pinjingjing

  Its endurance really surprised me. After being fully charged, it can last 60 days after being used for ten minutes every day (the data comes from the official)! You can also switch between cordless ropes, skipping rope will hit you and those who won’t hit you are happy ~ the numbers are still displayed on a big screen, and the backlight design allows us to easily read during the jump.

  And this one is the same as the four-character brother’s endorsement. If you round it off, we will jump in the same rope with our brother. Hey, hey (idiot face)

  Move it intelligent dumbbell

  Reference price: 199

Cr: Little Red Book @ Lucky

  I didn’t see this dumbbell before, but it just added a little weight. I practiced it differently when I filled it with mineral water bottles at home. But this dumbbell really opened the eyes of the flowers, and sure enough, even small dumbbells should be injected with scientific and technological ingredients in the technological era.

  It has a built-in high-precision induction module, which can accurately identify every movement of the athlete. When it is matched with the brand software with the same name, if the movement is accurate, it will appear corresponding prompts such as perfect and good (how do you feel like playing with pleasure? ), when the action is wrong, it will be encouraged. It can also invite friends to exercise with friends PK, which will greatly improve our enthusiasm!

Cr: Little Red Book @ Little Lucky/@ Little Sister B

  Moreover, it is designed with polymer silicone, which is healthier and more environmentally friendly, does not harm the skin and feels comfortable at the same time. After exercise, the round end of the dumbbell can also be used as a massage ball to relax the muscles. It is not wasted anywhere on such a big thing, and the money is not lost ~

  Babies who have a little budget for fitness and don’t want to go to the gym all the way can look here. These things are enough for you to open a small family gym ~

  Mairuike spinning MR-655

  Reference price: 1280

Cr: Taobao official

  The brand Merrick may be unfamiliar to everyone, but it is actually a partner of the Training Bureau of the State Sports General Administration, which will provide athletes with a variety of training and fitness products. Isn’t it another step away from the Olympic champion?

  This spinning bike is a good-selling product of its family. Small size, occupying only 0.07m2, can be placed in any corner, whether in the living room, kitchen, balcony or bedroom. Different from the traditional spinning bike design, it can also liberate the upper body, so that we can exercise while studying, working, playing games and watching TV, and become a proper time management master.

  Moreover, its magnetic flywheel operation makes its noise very small, and eight kinds of intelligent gears can meet the different exercise intensity needs of a family. Huahua also tells you that its seat can be adjusted in height, and tall people with legs of 1.8 meters don’t have to worry about not being able to stretch ~

  Aomashi multifunctional stepping machine OMS-T8

  Reference price: 1380

Cr: Xiaohongshu @ Chongya XyaN

  This treadmill, Huahua would like to call it a "lazy sports artifact", which can achieve the effect of exercise only by moving its feet. Its size is also very small, so you can take it home even if the home area is not big enough ~

  When doing homework, Huahua sees that many people are worried that the treadmill will hurt their knees. However, when this treadmill moves, the trajectory of the machine is elliptical, which can avoid the impact and pressure on all joints of the body during exercise, and can protect the knee joints and reduce injuries.

Cr: Little Red Book @ Panda

  It also has 8-speed intensity that can be adjusted, and the babies can gradually increase their resistance with the increase of exercise intensity. The magnetic control device can reduce the movement noise, and the drawstring that comes with the machine can unlock various movement modes, which can be practiced on waist, abdomen, legs and arms. Let’s do the exercise while standing ~

  Switch fitness ring+host

  Reference price: 2398

Cr: xiaohongshu @ minychong

  Switch’s fitness ring has been spent for a long time, and many people have seen it since the early days of the epidemic. It recognizes our movements through "Ring-con" and "leg straps", and when we make corresponding movements, we can push the game characters forward to break through the barrier.

Cr: Little Red Book @ A Zi is a little blessed/@ Ghosts.

  It will fight when it meets the enemy in the process of crossing the border. We need to use our bodies to make various gestures to defeat the enemy and move on, which sounds very interesting. Moreover, as the difficulty of breaking through the barrier increases, we will grow up with the protagonist in the game, and for families with children, we can also entertain and educate, and playing games will no longer delay our study and health ~

Cr: Little Red Book @Rxuan/@ Mai Girl's Little Match

  In addition, there is a dance fitness game-full dance power, a lot of popular songs, following the movements of animated characters all the time, and exercising happily in music and rhythm. For most people, fitness is no longer a chore.

  Although its cassette is not expensive, it needs to be used with the host computer, so the overall price will be a little more expensive, but the host computer can also be used with other game cards, which is equivalent to buying a multi-functional game machine with a fitness function, so you don’t lose money!

Cr: This account number, please indicate the source when reprinting.

  Babies who work out at home may worry about what to do if their movements are not standard. If you have FITURE, a smart mirror for home fitness, you can dispel this concern. It uses AI intelligent black technology to guide in real time, correct wrong actions and avoid injuries caused by wrong actions during the exercise.

Cr: This account number, please indicate the source when reprinting.

  There are 16 types of courses such as strength plasticity, yoga, aerobics and pilates on FITURE’s APP, and each course has different training parts, and you can practice in different patterns every day. The coaches inside are all star coaches from FITURE’s self-research, and their professionalism is excellent. Although it is just a mirror, it can also customize its own fitness course according to the physical test results, just like inviting a private tutor at home to serve you 24 hours a day, 365 days a year.

Cr: xiaohongshu @FITURE family science and technology fitness

  But also with nutritionists and health consultants, exercise and diet combined to help us achieve fitness goals faster. In addition to sports, we can also exchange experiences with fitness instructors and partners in FITURE’s community and make more friends.

  With so many products introduced, I don’t know which one you prefer, but in fact, as long as we have perseverance, we can do it anytime and anywhere. I use the money from the gym to buy some equipment for myself to practice at home, which is affordable and convenient. I don’t have to worry that the gym is too far away and the epidemic is suddenly isolated. How nice it is to easily realize the freedom of fitness ~

In 2022, can these four domestic new energy vehicles go against the sky?

In 2021, new energy vehicles in China sold like crazy, and the annual sales of 2.989 million vehicles seemed to make the phrase "the internal combustion engine will eventually end" more and more solid. In recent years, we can no longer hear the cynical argument that "trams are also cars", and the models with green plates have gradually moved from being ridiculed to the center of the stage.

The Year of the Ox is over, the bull market will continue, and the brand-new Year of the Tiger is coming again. In the new year, among the known new energy vehicles (whether listed or not), which ones are particularly worthy of optimism? What models can further subvert our perception of new energy vehicles?

■ Zero-run car-C11

In September 2021, the retail C11 was officially listed, and the "price butcher" that everyone waited for officially entered the market. The post-subsidy guidance price of 15.98-19.98 million yuan can only be said to be tough enough.

The pure electric vehicles at this price have caught a lot in the market. Why did the retail C11 win such high praise as the "price butcher"? We can roughly summarize it with three advantages of C11.

Advantage 1: Grade, size and wheelbase are all interesting.

Pure electric SUVs within 200 thousand are dominated by compact cars, and medium-sized cars are few and far between. In terms of wheelbase parameters, C11 is also the longest one for the time being. Of course, C11′ s proud wheelbase is not only within 200,000.

If you want to choose a pure electric car that can be used as a home within 200,000, the dimension wheelbase is a must-see parameter, and the C11 is almost a car that you need to know.

Advantage 2: the battery is big enough and the battery life is enough.

Three electric systems are the lifeblood of pure electric vehicles, and battery life is the most concerned topic for consumers. In the exclusive rear-drive model and four-wheel drive performance model, C11 uses a battery pack consisting of 216 batteries, with a capacity of 90kWh and an energy density of about 180Wh/kg, which is temporarily at the top of the list among models within the class of 200,000.

Advantage 3: the configuration is high enough

Four-door internal electric opening+frameless door, this configuration is also unique in models within the 200,000 class. In addition, the front laminated silent glass, four-door window one-button lifting and other configurations are all standard in C11.

Inside the cabin, the horizontal and vertical space of the C11 can be said to have no choice. The standard three large screens also directly fill the sense of technology. The front seat electric adjustment, face recognition, Nappa leather steering wheel and other configurations are also standard in the whole department.

Since it is a "big car" in the same price range, the retail C11 needs to meet the demand for family cars. Perhaps because of this, C11 chassis naturally chose comfortable orientation adjustment. At the first test drive of C11, I was deeply impressed by the performance of this car when it passed through the continuous speed bump. The soft damping in the initial stage of the suspension allowed C11 to resolve the continuous fine vibration in place.

Car owners with a budget of 150,000-200,000 yuan are often highly rational, and the entry-level luxury brand models at this price are less competitive. In the self-owned brand models, the product strength of C11 is also attractive enough. At present, C11 is still in the process of capacity climbing, and the delivery time of the vehicles currently ordered will be in Q2. If the capacity is improved, I believe the sales data will show the popularity of C11.

The retail brand will also borrow C11 to reach new heights.

At present, there are three platforms, S, T and C, of which platform C is a medium-sized car, and the brand-new zero-run C01 will share the platform with C11.

The zero-run C01 will be the first vehicle with CBC chassis and battery integrated design. Officials say that the space utilization rate of the battery compartment of the new car will be increased by 5%, and the overall torsional stiffness of the car body will be increased by 25%. The new car will also be equipped with a dual-motor four-wheel drive system. It is reported that the CLTC life of the zero-run C01 is around 700km.

In the next four years, Zero Run will launch eight new models one after another and enter overseas markets, including SUVs, MPVs and cars. The wheelbase ranges from 2600mm to 3100mm, and these new cars will cover the price range of less than 350,000 yuan.

In the new year, the attack of zero-running cars is very worth looking forward to.

■ gaohe automobile-hiphi z

In 2021, with the official or spontaneous publicity from Weibo, Tik Tok, Aauto Quicker and friends circle, both Gaohe Automobile and HiPhi X, which is famous for playing the door, earned enough traffic. HiPhi X with a guide price of 570,000-800,000 yuan can be described as the price ceiling of domestic pure electric vehicles, and the cumulative sales of this car in 2021 and the sales of 919 vehicles in December are really good.

Does Gaohe need a younger brother who can walk more? Maybe they don’t have this plan yet.

In November, 2021, Gaohe Automobile released the second flagship model-Gaohe HiPhi Z mass-produced stereotypes car.

95% of the mass production content of HiPhi Z has been locked, and the new car will be unveiled and booked during the auto show in April this year, and mass production will be delivered in 2022.

Gaohe, which has a flagship, will play a double flagship this year.

The appearance of digital mecha of HIHIHIZ is very eye-catching, and the tough and sharp lines are unique, bringing the future shape of science fiction. The first thing that people remember is the "Breathing Scales" grille (AGS active air intake grille) on the front face. Just like HiPhi X, the headlamps with sharp straight waterfall have programmable lighting design functions.

HiPhi Z retains the "electromagnetic NT split door" on HiPhi X, and this design is likely to become a major symbol of Gaohe automobile in the future.

At the door position, HiPhi Z is equipped with the world’s first "Star Ring ISD Light Curtain System", which can display rich human-computer interaction information. The 22-inch "flexible armor wheel hub" with low vehicle lines vividly demonstrates the fighting GT style.

HiPhi Z’s "Digital Mecha Cockpit" uses the magic color style, and the "Galaxy Band" atmosphere lamp on the door panel and the luminous panel with mechanical beauty construct the surrounding emotional system inside the car. Every time the light flashes, it is the emotional echo between HiPhi Z and users.

Gaohe HiPhi Z is equipped with a self-developed HiPhi Pilot intelligent driving assistance system, which makes it a safe and reliable driving partner in multiple scenarios.

HiPhi Z is equipped with 31 driving assistance sensors, including 2 forward 8-megapixel high-definition cameras, 1 backward 2-megapixel camera, 5 millimeter-wave radars, 1 laser radar and 4 lateral cameras. Combining the radar accuracy with visual intuition, and cooperating with high-precision maps and positioning modules, HiPhi Z will be endowed with the future autonomous driving ability of 5G+V2X.

Regarding the establishment of the luxury smart electric vehicle brand, Gaohe Automobile has a clear position. Driven by HIP-HI-Z and the double flagship strategy, Gaohe can further consolidate its position in the first camp of luxury new energy vehicles with a price of over 500,000 yuan.

Remember the hot scene of Gaohe automobile booth in previous auto shows? I believe that in the auto show in the near future, Gaohe will be the focus of the audience again, and we will bring you more information about HiPhi Z at that time.

■ Guangzhou Automobile Aian-Aion LX Plus

"If the battery life is 1000+km, I will buy a tram"-netizens often say so. With the advent of AION LX Plus, the "1000+km" pure electric vehicle finally appeared.

Although we all know that 1000+km in the eyes of netizens requires a car to actually run to 1000+km, no matter whether it is driving at high speed or in the cold.

That’s a bit difficult for people! At present, we have started to own the first pure electric vehicle with a test score of 1000km+, which is a big step of success.

Some time ago, the electric state conducted the endurance test of AION LX Plus, and the model version officially attracted much attention. This model is equipped with a large battery pack with an exaggerated capacity of 144.4kWh, and the NEDC cruising range is 1008km.

The general outline of the test is as follows:

① Set the air conditioner to 22℃ in the whole process, turn on the seat for heating, and test the temperature at 4℃ to-8℃;

② The journey route is-Tangshan-Qinhuangdao, only taking the national highway and urban/rural roads, with a total length of about 420km;;

③ The return route is Qinhuangdao-Xianghe-,and the whole journey takes the expressway, with a total length of about 240km.

In the end, this 1000-kilometer version of AION LX Plus delivered a score of 675km, with an average power consumption of 17.5kWh/100km. Based on the battery capacity of 144.4kWh, the final redemption rate of AION LX Plus was as high as 81.9%.

Calculation method: (144.4/17.5*100/1008= 81.9%)

When using a short battery life pure electric vehicle, we are more likely to pay attention to its battery life redemption rate; When using a long battery life model, we are more likely to pay attention to how much its actual mileage is worse than NEDC battery life. In fact, we are more likely to choose to observe the numbers that make us anxious.

In cold weather, we are very satisfied with the endurance performance of AION LX Plus, and believe that this car can perform better under more favorable working conditions for pure electric vehicles.

AION LX Plus adopts "sponge silicon negative plate battery technology", which is also the mystery that this car can push NEDC battery life to 1008km.

The theoretical specific capacity of graphite is 372mAh/g, and that of silicon is 4200mAh/g, which is 10 times that of graphite. In order to prevent the crystal lattice of the silicon negative electrode material from expanding (up to 300%), GAC Aeon changed the silicon negative electrode sheet into a soft and elastic "sponge texture", which effectively eased and inhibited the expansion after the lithium ion was embedded, and there was no pulverization or shedding.

Under the new technology, the battery cell can be reduced by 20% in volume and 14% in weight, thus ensuring that the AION LX Plus equipped with sponge silicon negative plate battery technology can run further under the premise of the same battery quality.

Pure electric vehicles have almost bid farewell to the "battery competition", and today’s consumers are not only concerned about battery life. In order to stabilize the status of the family flagship, AION LX Plus does not dare to relax in terms of intelligent technology.

AION LX Plus is equipped with the industry’s largest number of 35 high-performance sensing hardware. At the same time, this car is also the world’s first production car equipped with three second-generation intelligent zoom lidar.

With rich hardware system and high computing power intelligent driving computing platform, AION LX Plus has a powerful urban NDA system, which can realize high-level operations such as straight ahead at traffic lights, autonomous lane change overtaking, left-right turn at traffic lights, U-turn and traffic around the island.

After putting on the new family front face, the AION LX Plus looks more like a flagship model, and this design has almost helped the entire Ai ‘an family get rid of the shadow.

Perhaps the "showing muscles" in the thousands-mile version of AION LX Plus means a lot, and its sword refers to the price of BBA’s main medium-sized car, which makes people feel a little brave. However, the fast running of the train depends entirely on the headstock. There is a thousand-mile version of this big brother to hold up the facade. The flagship gas field of AION LX Plus is quite sufficient. I wish this rejuvenated flagship can help the Ai ‘an family to expand its territory in the new year.

■ aito-ask the world M5.

Huawei Yu Chengdong once said at a press conference: "Huawei has all the ability to make a car, but Huawei doesn’t make cars. Huawei’s goal is to help car companies build and sell good cars. "

Huawei has repeatedly made high-profile claims that it does not build cars, so we will pay special attention to anything related to building cars. And if we really study Huawei’s "no car theory", it is too true.

In fact, Huawei is not entirely a supplier, but a wily big boss.

Huawei not only participated in the production of electric drive system, intelligent cockpit and auxiliary driving parts, but also escorted the software, marketing strategy and sales channels of the new car. Although this car does not wear Huawei LOGO, it is obviously a "pro-son" treatment. Perhaps in the eyes of passers-by in shopping malls, this is a Huawei car.

The models of high-end brands must not be vulgar, and it is not advisable to be too conservative or too radical.

The M5 has obviously found a good balance point. This car uses more curved surfaces, and its front face has an elegant smoky "big mouth" radian and a clear sense of hierarchy.

The M5 includes two power forms: rear drive and four-wheel drive. The four-wheel drive model adopts a dual-motor four-wheel drive scheme with asynchronous AC motor on the front axle and permanent magnet synchronous motor on the rear axle.

Among them, the maximum power of the four-wheel drive flagship model can reach 365kW, the acceleration time of 0-100km/h is only 4.4s, and the acceleration of 0-50km/h is as low as 1.9 s; The maximum power of the four-wheel drive performance version can reach 315kW, and the acceleration time of 0-100km/h is 4.8 s; The standard version of rear drive is also equipped with a high-performance motor with a power of 200kW, and the acceleration time of 0-100km/h is 7.1s.

Wenjie M5 is equipped with a ternary lithium battery pack with a capacity of 40kWh, and its pure battery life is 150km under WLTC condition. Combined with the fuel tank with an upper capacity of 56L, the total cruising range of this car can reach 1102km in WLTC and 1242km in CLTC.

The big screen and car system are all good at Huawei.

Wenjie M5 is equipped with Huawei Harmony OS car system, which can combine users’ full sensory operation and realize seamless interconnection among people, mobile phones, smart homes, smart watches and other devices.

Inside the M5 cockpit, the word "HUAWEI" can be seen everywhere, which is reflected in the sound hole, under the bar and in the area of wireless charging panel. This new car with Huawei everywhere will be put into more Huawei flagship stores. With Huawei’s strength, influence and hands-on, this car has its own topic, and I don’t know how much advertising expenses have been saved.

In 2022, it’s time for the M5 to "hand in the paper". Let’s look forward to the sales performance of this car!

■ Write at the end

In this issue, we didn’t look forward to the progress and performance of the relatively more popular Weilai ET series, Krypton 001 and other models in the new year. After all, everyone has paid enough attention to those models.

Whether it’s the retail C11 whose sales volume has not yet bloomed, the Gaohe automobile belonging to a few people, the previously bleak but brand-new AION LX Plus, or the AITO Wenjie M5 that is ready to go, these models all have their own expertise in their respective fields, which is very worthy of attention. In the new year, I also wish these models to be known by more people and achieve good market performance!

Empathy! "Hot Search" Chengdu roadshow news students were deeply touched.


1905 movie network news The film directed by, starring, and starring is being shown. Yesterday, the national roadshow "Hot Search" and "Sound All the Way" came to Chengdu.

It is a matter of special courage to stand up and help people who are being hurt". Some viewers said that they were deeply impressed by the lyrics of the ending song Byakki Smoker, which reflected the difficulties faced by many women. The director said frankly that he hoped to "record the distinctive power of women’s mutual assistance in this era and the plight of different classes in their depths" through the film.


There is also a lawyer audience at the scene who said that he has already brushed the film twice, and he was deeply touched. "The current network environment is very complicated, and public opinion supervision is very important, but there must be no public opinion trial, which may make the parties face social death on the Internet first." As a legal practitioner, I will try my best to ensure that every case is echoed in fairness and justice. Song Yang said: "The network can make a sound. I hope that everyone can make a sound when they are hurt, and gather into a fire to overthrow all evil forces."


The film "Hot Search" is showing.

For the first time in 32 years, the list of wild animals has been greatly adjusted: 517 species have been added and species protection has been upgraded.

The State Forestry and Grassland Bureau and the Ministry of Agriculture and Rural Affairs jointly issued an announcement recently, announcing the newly adjusted List of National Key Protected Wild Animals (hereinafter referred to as the List). This is the first time that the Catalogue has been greatly adjusted since it was promulgated and implemented in January 1989.
Why should the Directory be substantially adjusted? What are the highlights of the adjustment? What impact will it bring to wildlife protection? The reporter interviewed relevant experts and scholars.
Sixty-five species of wild animals, such as jackals and Yangtze finless porpoises, have been upgraded from national second-class protection to national first-class protection, and 988 species (categories) of wild animals have been included in the new Catalogue.
According to the Law on the Protection of Wild Animals, the state implements classified and graded protection for wild animals, and gives priority protection to rare and endangered wild animals. Wild animals under special state protection are divided into first-class protected wild animals and second-class protected wild animals. After the publication of the Catalogue in 1989, until this major adjustment, there was no systematic update except that all species of musk deer and pangolin were upgraded to national first-class protected wild animals in 2003 and 2020 respectively.
"In the past 30 years, the situation of wildlife protection in China has undergone great changes." Jiang Zhigang, former executive deputy director of the National Endangered Species Science Committee, said that some endangered wild animals have been effectively protected, and the degree of endangerment has been alleviated, while the degree of endangerment of some wild animals has intensified, and a number of new rare and endangered species have been discovered with in-depth research and need to be protected in time. It is necessary to scientifically adjust the Catalogue.
The new Catalogue has changed a lot, and the range of wildlife under special state protection has greatly increased. From this set of data, the great change can be seen:
—— On the basis of retaining all species in the original Catalogue, 517 species of wild animals have been added, which is more than the total number of previously protected species. Among them, 43 species such as the spotted civet cat are listed as national first-class protected wild animals, and 474 species such as wolves are listed as national second-class protected wild animals;
-Raising 65 kinds of wild animals, such as jackals and Yangtze finless porpoises, from the national second-class protected wild animals to the national first-class; Three kinds of wild animals, the bear monkey, the capra ibex and the python, were adjusted from the national first-class protected wild animals to the national second-class;
A total of 988 species (classes) of wild animals are listed in the new Catalogue, including 234 species and 1 class of wild animals under national first-class protection and 746 species and 7 classes of wild animals under national second-class protection. Among the above species, 686 are terrestrial wild animals, 294 and 8 are aquatic wild animals.
The newly discovered endangered species have attracted much attention in this adjustment of the Catalogue. "This adjustment has timely included precious and endangered species newly discovered and recorded in China in recent years." Shi Kun, director of the Wildlife Research Institute of Beijing Forestry University and professor of the School of Ecology and Nature Conservation, said that species such as white-cheeked macaque, lazy bear and red gazelle are small populations or marginal distribution in southwest China, which have important ecological functions and need to be protected.
Incorporating into the scope of national key protection and upgrading the protection level means that the protection of species has increased significantly.
It is noteworthy that five species, including Tibetan antelope, Tibetan wild donkey, bear monkey, capra ibex and python, were proposed to be downgraded to the second level in the draft of the Catalogue, but only three species, namely, bear monkey, capra ibex and python, were downgraded in the officially published Catalogue.
"The populations of bear monkey, capra ibex and python are stable and widely distributed, and they are downgraded, which reflects the effectiveness of protection work and is also based on the conclusion of scientific assessment." Shi Kun said that Tibetan antelope and Tibetan wild donkey have not been downgraded, mainly because they are worried that the illegal cost of destroying species will be reduced after demotion, which may lead to a rebound in poaching and threaten the survival of species.
Why did the new Catalogue add so many species? Zhang Wei, a professor at the College of Wildlife and Nature Reserve of Northeast Forestry University, believes that on the one hand, China has continuously strengthened biodiversity protection, and its ability to protect species has become stronger and stronger, and it has the ability to include more species in key protection areas. In recent years, China has accelerated the construction of a nature reserve system with national parks as the main body, with a total of 11,800 nature reserves, accounting for 18% of the land area, effectively protecting 90% of vegetation types and terrestrial ecosystems and 85% of key protected wildlife populations; At the same time, the protection of endangered wild animals has been continuously strengthened, and a stable artificial breeding population has been established for more than 300 endangered wild animals. On the other hand, with the development of taxonomy, many changes have taken place in the animal classification system, and this important change has been taken into account in the adjustment of the Catalogue, which has also led to the increase of species included in the scope of protection.
Incorporating into the national key protection scope and upgrading the protection level means that the protection of species will be significantly increased. Species protection and upgrading, protection projects and funding will increase, which is of great significance to the gradual recovery of populations and habitats.
"Different levels of protection also mean that there are different sentencing standards for cracking down on poaching, illegal smuggling and illegal trafficking." Jiang Zhigang said that the adjustment of the Catalogue has brought new opportunities for the protection of a large number of rare and endangered wild animals.
For key protected species, a rescue plan should be made as soon as possible to restore the population and habitat of threatened species.
The substantial adjustment of the Catalogue has undoubtedly put forward higher requirements for wildlife protection.
"The adjustment of the Catalogue to include more species requires supporting funds, technology and personnel, and relevant departments should formulate supporting management measures." Jin Kun, director of the Nature Reserve Research Institute of China Academy of Forestry, said.
Shi Kun suggested that after the species are included in the national key protection scope, a rescue plan should be made as soon as possible to restore the threatened species population and habitat. Combined with the construction of protected areas, efforts should be made to protect the habitats of rare species.
Clear responsibilities, do a good job of coordination, and keep up with capacity building.
Shi Kun believes that the inclusion of species in the scope of national key protection does not mean that only the state has the responsibility to protect. The local authorities should cooperate with the state to strengthen the capacity building of grassroots protection and implement the responsibility to the county level. Jin Kun also said that the protection of wildlife under special state protection should embody the principle of concentrating resources and giving prominence to protection. The species between the national and local key protection lists should be balanced, and the responsibilities of the central and local governments should be clarified so as to facilitate management and law enforcement. "Some species are included in the national key protection ranks, and the staff of supervision, law enforcement and other departments should further learn and master relevant knowledge, such as identification technology and punishment standards." Jin Kun said.
Only by strengthening supervision and public participation can protection be effective.
In the new Catalogue, more than 60 species are labeled as "wild populations only". In this regard, Shi Kun explained that some species have mature breeding techniques and stable artificial populations, which are listed in the National Catalogue of Livestock and Poultry Genetic Resources, such as sika deer and red deer. "This labeling distinguishes the wild population and artificial population of species, and does not engage in’ one size fits all’, which embodies the concept of sustainable development. Of course, it is necessary to strengthen supervision and crack down on illegal hunting of wild populations as artificial populations. "
Jiang Zhigang said that the protection of wild animals should not be at the expense of local residents’ interests. It is necessary to increase financial transfer payments, improve the ecological compensation mechanism and the compensation mechanism for wildlife damage, guide local residents to benefit from wildlife protection, attract them to take the initiative to participate, and truly realize the harmonious coexistence between man and nature.
The wildlife protection law is clear, and the Catalogue is adjusted every five years according to the assessment. "This adjustment is comprehensive, scientific and realistic, but there is room for further adjustment." Jin Kun said that it is necessary to increase investment in scientific research, intensify the investigation and monitoring of species resources, scientifically evaluate the population status, regularly update or adjust the Catalogue according to the actual needs of wildlife protection, and build a reasonable entry and exit mechanism for the Catalogue.
The relevant person in charge of the State Forestry and Grassland Bureau said that it will further strengthen protection, implement local government responsibilities, ensure the safety of rare and endangered species and habitats, strictly enforce law enforcement and supervision, and severely crack down on illegal and criminal activities. At the same time, publicity and education will be widely carried out to improve public scientific cognition, guide the public to consciously resist illegal acts and support protection work, and form a good situation of joint protection from all walks of life.

How did the whistle and brilliant colors of fireworks come about?

When Xiao Bian was very young, he liked to run to the balcony to watch fireworks every New Year. After a bang, a bright and colorful fireworks burst into the distant sky, gorgeous and beautiful.
All kinds of fireworks @Wikipedia
Therefore, Xiao Bian, who was young and ignorant at that time, couldn’t help wondering … Why did a small box on the ground look like that after being ignited? How on earth are fireworks designed and made in order to show such a brilliant effect?
The picture comes from the Internet.
There are many kinds of fireworks, and the fireworks seen in general TV programs, that is, the kind that flies to the sky with a bang and then explodes, are a special kind of fireworks called fireworks.
Fireworks @Wikipedia
Fireworks bloom can be roughly divided into two stages. The first stage is the launch of the fireworks bomb: with a bang, something on the ground flew into the sky. The second stage is probably the burst of fireworks, and a firework exploded in the sky. What happened in these two stages respectively?
The internal structure of a certain kind of fireworks is probably like this [1].
Fireworks structure @pyrouniverse.com
Hit the fireworks into the sky
When we lit the fuse (fast fuse), the fuse gave the friends time to evacuate and delayed the explosion. When the fuse burns to the propellant, ignite the propellant. Propellant is generally black powder discovered by the ancient alchemist in China. After the fireworks are lit, the sound of "bang" is the explosion of this thing. The main components of black powder are sulfur, charcoal and potassium nitrate, and the reaction formula of explosion is complicated. A typical chemical reaction equation looks like this (familiar with one sulfur, two nitrates and three carbons):
This explosion reaction produces a lot of heat and high-temperature gas, which is similar to the principle of rocket launch. The high-temperature gas produces huge thrust and pushes the shell into the sky. In the process of flying high into the air, we often hear the whistling sound, which is a sound effect of fireworks. It comes from a special thermal-acoustic coupling combustion-pulsating combustion.
Pulsating combustion
Pulsating combustion is a special unstable combustion process, and the parameters such as temperature, pressure and airflow speed in the combustion zone will fluctuate periodically with time. In the process of industrial application of pulsating combustion, there will be a lot of noise radiated from the tail pipe of the burner [2]. This technology involves many nonlinear processes of thermo-acoustic coupling, large amplitude acoustic wave effect and so on, which is very complicated, so there is no relevant theory at present [3].
But the fact that there is no relevant theory doesn’t mean that we are not here or can’t use it.
People engaged in fireworks production already know that in order to make fireworks produce this whistling sound, it is necessary to use a special kind of combustion product-flute agent. Oxidizers (potassium perchlorate and potassium chlorate) and flute agents (mainly derivatives of benzene) are mixed and packed into paper or plastic tubes, and pulsating combustion will occur after ignition, resulting in crisp flute sound [4].
@ References [4]
This pulsating combustion causes thousands of violent vibrations of air every second, releasing high-frequency sound waves. Therefore, the combustion chamber loaded with flute agent and oxidant acts as a propeller, and at the same time, it also emits a sharp whistle-like sound.
In addition to the fireworks launched, there is also a famous fireworks with sound. Xiaobian’s hometown likes to call him a monkey, which is this thing:
@bilibili-av8389766
The ingredients of the propellant used in this kind of thing are potassium perchlorate and potassium hydrogen phthalate. And this potassium hydrogen phthalate, as can be seen from the above table, is also a flute agent (although the sound frequency emitted by combustion is unstable, it still produces a sound pressure of 100dB).
Burst out a firework.
After the propellant is detonated, the delay lead is ignited and the time is started. By the time the shell flies to high altitude and needs to be ignited, the delay lead is almost burned out. So the explosive was detonated and the stars were blown all over the sky. The figure of the fireworks explosion depends on the position of the stars in the shell. If the medicine makes the fireworks explode into a specific shape, it is necessary to design the arrangement of the stars in the fireworks subtly [5].
What the hell is this star? It is the most crucial and mysterious part of the whole fireworks display ~
Its main components are magnesium powder, potassium perchlorate and metal salt or metal powder [6].
Star Composition @ Paperclip-How to Make Explosive Fireworks
After the star is ignited, magnesium powder as reducing agent and potassium perchlorate as oxidizing agent burn violently, giving off a lot of light and heat (but not gas) and becoming the shining things in the fireworks.
But how did the colors of fireworks come from? This involves an important phenomenon related to physics and chemistry-flame reaction.
flame reaction
Simple metals or their compounds will evaporate into individual particles at extremely high temperature, and only individual particles can exhibit flame reaction. (There is no flame reaction in bulk solid samples, because the luminescence of bulk materials is mainly related to the movement of electrons in the materials, and there are various electrons in different movement states in bulk solid samples, so the spectrum of light emitted by bulk materials is very wide and does not present a relatively single color [7]). However, the free metal simple substance or metal ion in the flame will be excited to an excited state with higher energy at high temperature.
However, the excited atom at higher energy is unstable, and it will always transition to the most stable ground state with the lowest energy. In this process, the photon energy (hν) emitted by the atom is exactly equal to the energy difference between the excited state (energy E2) and the ground state (energy E1).
@Wikipedia
The wavelength of photons emitted in this way does not depend on the temperature of the evaporated metal particles, but only on the energy difference between the two energy levels where the transition occurs, and this energy difference is only related to the kind of atoms.
Therefore, different metal ions will have different colors. In this way, we can use various metals and metal compounds to produce various colors.
The metals or metal compounds in the stars, heated by the huge heat released by the burning of magnesium and potassium perchlorate, emit their own light through the flame reaction.
The color of flame reaction [8]
tag
It’s been more than a dozen Spring Festival from a silly child who knows nothing to today’s Xiaobian. Looking at the manuscript, I can’t help but think of myself skipping in front of fireworks more than ten years ago. Time flies, the sun and the moon fly. Although it is more and more difficult to see the fireworks bloom, their physical and chemical principles are becoming more and more clear.
Anyway, it’s the Spring Festival. While enjoying the beautiful and gorgeous fireworks, don’t miss the same beautiful and gorgeous physical and chemical principles behind the fireworks ~
Ps: Places where fireworks and firecrackers are prohibited should strictly abide by the regulations.
