Unlike McDonald’s high-profile packaging of China stores for sale, KFC, another iconic American fast food chain giant, unexpectedly sold its China business in a low-key manner. The night before yesterday, Yum! Brands, the parent companies of KFC and Pizza Hut and listed on the new york Stock Exchange, announced that Yum! China would be separated from Yum! Brands and listed on the NYSE as an independent company. At the same time, after the spin-off, Yum! China will receive a total investment of US$ 460 million from Chunhua Capital and Ant Financial. This means that Yum! Brands has sold part of its operations in KFC and Pizza Hut in China to two purchasers from China.

　　Yum!’ s business in China has fallen into a trough?

　　In fact, Yum! Brands has already paved the way for China business. Last October, it announced that it planned to split Yum! Brands and Yum! China, and this transaction was carried out on the basis of that split at that time.

　　KFC is the first American fast food chain brand to enter the mainland market in China. In 1987, it opened its first store in Qianmen, then the most prosperous business district in Beijing. At that time, it was fashionable for both Beijingers and foreign tourists to queue up for a fried chicken or a hamburger at KFC. And KFC’s rule of "throw away the food after it has been sold for 90 minutes" brought from the United States has also attracted the attention of consumers in China. It is likely that KFC’s great success in exploring the China market attracted McDonald’s. Subsequently, McDonald’s also entered the mainland market of China in 1990. For a long time after that, these two brands were the iconic brands of American fast food culture in China.

　　In 2015, China accounted for half of the global business of Yum! Brands. However, this data can’t hide its downward trend in the China market. Since the incident that Shanghai Fuxi reprocessed expired meat raw materials and changed the shelf life and supplied them to McDonald’s and KFC restaurants in July 2014, KFC’s single-store income began to decline continuously. Yum! China’s same-store sales fell by 16% in the third quarter of 2014, and almost all of them fell by double digits in the following three quarters. Parkson’s financial report for the second quarter of this year, just released in July this year, shows that the same-store sales of KFC in China increased by 2% year-on-year, but it actually climbed slowly from the low base of last year’s lowest valley. During the same period, the same-store sales of Pizza Hut in China shrank by 11%. Therefore, it is widely analyzed that the reason why foreign shareholders strongly demand Yum! Brands to spin off its business in China has something to do with the poor prospect.

　　The "China Golden Period" of franchising may have passed.

　　Franchising is an effective way for KFC to expand its business in the world. As early as 1993, it began to carry out franchising in China, and since 2000, it has only adopted the franchising mode of "not starting from scratch" in China. The so-called "not starting from scratch" means that KFC will hand over a mature and profitable restaurant to its franchisees. In this way, franchisees can put all their energy into the operation and management of stores without having to make preliminary preparations such as site selection, opening stores, recruiting and training employees. This greatly reduces the business risks of KFC franchisees. In the words of Su Jingshi, former president of Yum! China Restaurant Group Greater China, "franchisees can succeed only by maintaining." By this means, KFC has achieved rapid expansion in China, and the number of stores has reached nearly 5,000 by the end of last year.

　　However, KFC has set a high threshold for joining, and the transfer fee for each restaurant is as high as 8 million yuan. After that, the going-concern expenses include the franchise fee accounting for 6% of the sales and the advertising sharing fee accounting for 5% of the sales, and the first agreement is signed for at least ten years. At this point, McDonald’s joining in China is exactly the same, and even the joining fee and cost-sharing ratio are exactly the same. This is obviously not a simple imitation of who, but a careful calculation based on a rigorous business model.

　　In fact, no matter KFC or McDonald’s, its investment in the global business chain is more than the catering service itself, that is, it operates the store in a benign state by selecting a location. As can be seen from the income structure of the two catering giants, this part of the profits is far greater than their own stores. With KFC and McDonald’s reaching the scale of thousands of stores in China and gradually covering third-and fourth-tier cities, the blank market space in the future is getting smaller and smaller, and the golden period of realizing profits through joining and transferring has passed. Therefore, it may be the best time for them to "pack up and sell" their business in China.

　　Although the supply of raw materials, as well as the annual brand use and marketing promotion expenses exceeding 10% of sales are still the long-term benefits they can enjoy, it is obviously only a decimal for them. Moreover, with the increasingly fierce competition in the catering market in China, the future sales potential of these foreign fast foods is not clear.

　　The receiver may want to change the joining mode and continue to expand.

　　Judging from the current Chinese takers of foreign fast food, whether it is Chunhua Capital or Ant Financial, or BTG, Sanpower and Sinochem, which are interested in bidding for McDonald’s China business, their real intention is probably not to directly participate in the catering industry, but to graft their current business to achieve profits in a new expansion mode.

　　This can be seen from the caliber of Ant Financial. "Ant Financial will help Yum! China provide mobile payment services for its brands, including Alipay platform." In fact, although the online speculation of Ma Yun "finally achieved revenge for not being hired by KFC that year", in fact, Ma Yun is definitely a supporting role in this investment — — His total investment with Hu Zuliu of Chunhua Capital will only account for a few percent of Parkson China in the future. Even compared with Hu Zuliu, the $50 million invested by Ma Yun is too small, accounting for only a fraction of the total investment of $460 million.

　　In fact, it can be seen from the fact that no real catering enterprise is willing to take over the business of KFC and McDonald’s in China that these two brands are more tools for the industry, which may also indicate that their future development in China will not be too exciting. Even some people in the industry believe that China KFC and McDonald’s, which have been abandoned by their parent companies, may embark on a development path in China that is divorced from stores in other countries in the world.

　　I don’t know if it is the first move to merge into Ali. The Beijing Youth Daily reporter learned that KFC will officially enter Tmall on September 6. In the future, consumers can buy electronic coupons for KFC food in Tmall stores and then exchange them for corresponding foods in physical stores.

　　Financial observation

　　Kfcs are "old"?

　　Although in many countries, KFC and McDonald’s are still regarded as the representatives of American fast food industry and even the symbols of American consumer culture, in fact, in the United States, more and more people have begun to diversify their choices, especially the opportunities for the younger generation of Americans to enter KFC are decreasing.

　　In the first half of the year, the only cross-industry economic indicator of customer satisfaction in the United States, the American Customer Satisfaction Index, released the 2016 Restaurant Satisfaction Survey Report. It shows that the average satisfaction score of fast food restaurants in the United States this year is 79, but the scores of KFC and Pizza Hut under Yum! are below the average. McDonald’s ranked at the bottom of many participating fast food chain stores with a score of 69 points, and McDonald’s ranked at the bottom last year.

　　As for the poor performance of KFC and McDonald’s, some American businessmen believe that although this does not mean that the food quality of KFC and McDonald’s has declined, they are "really old" in the eyes of American consumers and can no longer be the most typical representative of American fast food culture.

　　In fact, in the China market, KFC and McDonald’s are also facing the same problem. With a new generation of young people becoming the main force of fast food consumption, McDonald’s and KFC are no longer their absolute first choice to experience foreign fast food, and a large number of other brands of fast food subdivide the China market. More crucially, no matter how the varieties cater to the taste of China population, the standard fried chicken, French fries, hamburgers and coke that KFC and McDonald’s take care of have become the global representatives of "junk food". More and more young families in China have kept their children away from such fast food restaurants, at least in first-and second-tier cities.

　　For KFC and McDonald’s in China, the aura of standardization and trustworthiness that they were most proud of in the past has also been shattered with repeated food safety incidents. No matter Sudan red or fast-growing chicken, and then to the Shanghai Fuxi incident, these foreign fast foods have not been able to stay out of it.

Original SME SME technology story

Teenager, are you eager for strength? Want to be a hypnotist? Now all you need is a chicken, and hypnosis can be done quickly.

First, hold the chicken tightly so that its head is down and its beak is on the ground, and then draw a trace on the ground with chalk or fingers. Wait until the chicken is quiet and then let go of your hand, and you will get a new "stupefied chicken"

A "hypnotized" chicken

Of course, this is not true hypnosis, it uses the fear instinct of animals in the face of threats. Your fierce operation made it mistakenly think that a predator was close at hand, so it fell into a state of suspended animation (Thanatosis).

Hamiton Bertie Gibson, a British psychologist, mentioned in his book that the ultimate record of the longest time a chicken was hypnotized was 3 hours and 47 minutes.

In 1646, the German scholar Athanasius Kircher observed a chicken that went into suspended animation because of fear.

There are many animals that play dead in nature, and it also has a proper term called "tonic immobility".

This is a defensive strategy, which widely exists in mammals, birds, reptiles, fish and insects, and the "death method" is even more varied.

The 5-year-old girl in the CCTV program "Challenge Impossible" has "hypnotized" (scared) dogs, lizards, chickens, frogs and spiders, and was madly spit out.

It is precisely because suspended animation is so common that a number of so-called animal "hypnotists" have been made. They made a simple animal instinct magical and full of mystery.

There is a big brother who started a chicken farm, and even sold the local chicken at twice the price of the local market by the marketing method of "hypnotizing chicken". And those who buy chickens are really uneducated.

When confronted with a potential threat, two signals will immediately appear in an animal’s mind-"fight" or "flight", also called Fight-or-flight response. This is like the degree to which the brain has written, and you will choose between them, so that the body will respond quickly to better protect itself.

But in fact, in the case of "fighting" but not "escaping", our bodies can still fall into the third state-freeze.

Fight, flight and freeze displayed by Lego villains

When being touched at close range or feeling attacked, the rigidity of the prey may be triggered. But this state is not a decision made after careful consideration, but an involuntary defense mechanism.

They are really stiff and unable to move as if they had been acupoints. However, his brain is still spinning rapidly, and he is also alert to the changes in the surrounding environment.

On the surface, this rabbit enjoys the shower, but in fact, it has entered a state of suspended animation because of fear. Rabbits are prone to stress reactions and blind bathing is not recommended.

In fact, in the face of great pressure and threats, human beings will also have similar tonic static reactions. Have you ever tried, because you are too nervous, standing on the podium with your head blank and you can’t say a word?

In addition, when human beings are infringed, they often have temporary paralysis. Some researchers have talked with 300 women who have been sexually assaulted and found that 70% of them experienced obvious rigidity and stillness when they were attacked. They will be paralyzed, unable to scream, unable to resist, and their bodies will be completely out of control. Similarly, soldiers who have been on the battlefield have also had similar experiences.

It’s just that there are many mysteries about animal suspended animation. Because the matter of animals pretending to be dead is quite strange and full of doubts.

An animal faking its death is like taking its own life as a gamble. The success or failure of this gamble depends entirely on the foraging mode of hunters.

Fake dead frog

First of all, it is difficult to know whether the hunter will lose interest in the dead individual by pretending to be dead. If suspended animation can’t make hunters lose interest, then the poor guy who wants to get away with it by suspended animation will miss the best chance to escape. On the contrary, it makes the hunting work easier for hunters, and if they are not careful, they will directly change from "suspended animation" to "real death".

Moreover, the state of suspended animation can not reduce the sensory ability of predators to locate or identify prey, and it can not enhance the resistance of prey when attacked. Many times, this kind of rigidity and stillness will remain for a while, and the risk of being eaten seems to be even greater.

Fake dead bird

However, judging from the results of evolution, the strategy of feigning death is still useful with a high probability, and the overall advantages outweigh the disadvantages. If some predators delay eating, are not interested in dead things, and even find it difficult to distinguish still things, then the prey may escape.

In fact, obedience can really hurt yourself less. The state of rigidity and stillness can inhibit the further attack of predators and reduce the action of hunters to subdue their prey.

For another example, many top hunters will be more interested in the prey that is fleeing around, such as your cat, and the favorite is the cat-teasing stick full of soul. If the cat comes after a group of mice, and if all the other mice are running away, then the little mouse who is scared and unable to move is more likely to survive.

Similarly, most cases of feigning death belong to the "last desperate attempt", and it is an effective strategy to wait for hunters to relax their vigilance and find opportunities to escape. And fake death. Maybe it can really make some animals get to the end.

In nature, the best acting is the North American opossum (Didelphis Virginia), which deserves an Oscar in the animal kingdom.

It’s really not dead.

The North American opossum is the only marsupial living in North America. On the American continent about 70 million years ago, marsupial companions of opossums survived.

Only later, due to the rise of carnivores and other reasons, these marsupials with little resistance became extinct and went to the end. Only the opossum shoulders the fate of the whole marsupial, and survives tenaciously on the American continent, dealing with top hunters such as red fox, wolf, jaguar and short-tailed cat.

But it is in this case that the number of opossums in North America is still increasing. Among them, knowing how to play dead is a great knowledge and advantage for their survival.

The possum playing dead in Ice Age

Although the population of opossum in North America is huge, they are properly located at the "low end of the food chain", and almost any animal larger than it is a natural enemy. Therefore, opossums can only lie in the daytime and go out at night, and live by preying on insects, snails, birds, and occasionally eat some plants. In addition, the North American opossum moving on the ground without the shelter of trees is also clumsy and has poor defense ability.

When chased by the enemy to the end of the road, they will fall to the ground with a thud and enter a state of suspended animation-eyes closed, mouth slightly open, uvula spit out, belly swelled, tail drooping and winding in a circle, motionless.

When the dog comes, he can only pretend to be a dead opossum.

In order to be more realistic, the North American opossum will tremble slightly when it falls down, and its breathing and heart rate will slow down and its body temperature will drop while shivering. In addition, the glands near their anus will secrete a foul yellow-green mucus, which tastes like a highly corrupt corpse. If I don’t know, I really think it has been dead for three days and nights, and the body stinks. And this can often deter hunters and make it difficult to swallow.

It is precisely because of the grandiose acting skills of the North American opossum that people have specially invented a word "play possum" to describe the behavior of some people who pretend to be deaf and deaf.

Playing dead pig nose snake

Similar to the possum’s way of playing dead, there is also a pig-nosed snake. When encountering a hunter, the pig-nosed snake will bluff first, spread its neck ribs and make a horrible hiss, just like being possessed by a cobra.

But when bluffing doesn’t work, they will decisively enter the suspended animation mode, with their bellies turned up, their mouths opened to spit out the letter, and even oozing blood drops. The pig-nosed snake, like the opossum, also carries its own chemical weapons, which will give off an extremely unpleasant smell and very dissuade it.

Therefore, animals’ suspended animation is not simply lying on the ground, but they will also make themselves more difficult to swallow through various strategies.

What is even more surprising is that some animals in nature have learned to use the "rigidity and stillness" of other animals to hunt.

Whether in the wild, in captivity or in the laboratory, humans have long discovered that sharks, the top hunters, can also fake their deaths.

Turning the shark over and stimulating the skin around its nose may trigger the shark’s suspended animation for up to 15 minutes. Using shark’s suspended animation can also make researchers reduce the shark’s struggle and reduce the probability of injury to both sides when subduing sharks.

However, some people think that this rigidity and stillness of sharks is not due to fear, but related to reproduction. Studies have shown that after obtaining the mating right of the female, the male will also turn over the female body to cause rigidity and stillness, thus making the whole mating process smoother and easier.

But in any case, killer whales with IQ of off the charts seem to have seen through everything, and have learned to kill sharks by faking their deaths.

When encountering a shark, killer whales don’t rush to fight, but rush over and knock it over, biting the shark with their mouths so that it can enter a state of rigidity and stillness.

In 1997, someone photographed this precious picture of killer whales "outwitting" great white sharks off the coast of California, USA. Sharks in this state easily become the lunch of killer whales. Another example of killer whales "hypnotizing" their prey took place in New Zealand, and the victim was a stingray.

Fight scene in 1997

It can be seen that playing dead is really not omnipotent, and the "final interpretation right" is still in the hands of hunters. Finally, by the way, it is really useless to "pretend to be dead" when you meet a bear in the wild. If you meet a bear who has been hungry or sick, pretending to be dead is equivalent to sending a lunch box directly.

Special feature of 1905 film network　China art cinema has experienced a long development, from breaking the curse of box office failure of award-winning literary films in 2014 to shining brilliantly at this year’s Golden Rooster Award in China, literary films are welcoming new development opportunities. Today, Film Critics Today invited Shadan, a film critic who has been planning and screening in art cinema for a long time, to discuss with us the charm of art cinema.

According to incomplete statistics, 20-to 29-year-olds account for 60% of the total audience. More young people like literary films, and there are more controversies and labels surrounding it. Next, we will enter the quick question and answer session to see if you have the same misunderstanding about literary films.

Compared with other types of films, literary films have different missions and values. Professor Yin Hong of Tsinghua University once said: "Literary films focus on conveying the creator’s concern for human nature, society and history." Literary films are a very important part of the film industry, which plays a very important role in the cultivation of directors and audiences. In the early works of China’s fifth-generation directors, there are many films called literary film models, such as Harmony, which won many international awards that year. Thanks to the cultivation and cultivation at that time, today’s two movie master came into being. Art cinema’s creation nourishes young directors. Many young directors started with filming little art cinema, and they will become the main force of China films in the future. art cinema is a very important starting point in their lives.

At the same time, the existence of art cinema also ensures the diversity of big-screen movies. It is impossible for cinemas to have only popcorn blockbusters, but there should also be art cinema. Art cinema, as a very important cultural form, can provide many ideological sources for the audience and enhance their artistic aesthetic ability.

Art cinema should not be associated with box office failure. This year’s Golden Rooster Award-winning film "Mom! Is a very typical art cinema, and the box office performance is not bad. Shadan said: "In fact, we should not link this literary film with this box office failure. There is actually a big problem in this, that is to say, who are you going to film for? We also suggest that many young creators not only shoot some of their own stories, but also embrace the audience very enthusiastically and tell your story in a way that resonates with the public. "

In today’s Internet age, talented creators will not be buried, and there will be a large number of film selectors, curators and film critics to support them. art cinema, which is often shown in China Film Archive, is popular with audiences. Although these directors are shooting low-cost films, they have formed a very good reputation and brand among the audience.

@ Moderator Xiaoli:Then can you recall some wonderful clips, even those that may be controversial?

@ Shadan:For example, this movie is a very controversial movie, and its box office is very high, but many people (think) that its high level is achieved through the concept of "one kiss for the New Year" in commercial publicity and marketing. In fact, it is not a simple story about love, but a visual system made of a very complicated audio-visual language. The first scene of the movie is a very meaningful scene. A delicate hand actually carries a watch in his hand, telling you that at this moment, this man fell in love with me after being caught in my hand, and he will never forget me for the rest of his life. In fact, he has presented this very mysterious tone in this movie to everyone. In fact, there are more real meanings in movies than we imagined, so I think this is also a very important charm of art cinema, which is that you can keep pondering and watching, and every time you watch it, you will find something very fresh.

"If the racket falls, if it stops, then we will fall."

"Maybe it can fly."

In recent years, more and more successful cases have proved to us that as long as the film itself is good enough, it can always stand out. At last year’s Art Film Promotion Forum, Li Jie, president of Taobao Film, shared data: At present, Beijing and Shanghai occupy 70% of the box office in art cinema, China, and the proportion of Chengdu, Hangzhou, Shenzhen and Guangzhou is gradually increasing. This also shows that art cinema’s prospects and space are enormous.

@ Shadan:Many film festivals in Beijing and Shanghai are always hard to get a ticket, among which the ticket buyers are basically young people, and most of them are women. Women account for more than 65% of the ticket-grabbing links in the whole film festival. These audiences are all potential audiences of literary films. I am also thinking that if we can continuously establish this point-and-line national art film promotion network, we can find a lot of accurate audiences and cultivate them.

I believe this promotion mode will also promote our film creators to create more and better films. I also hope that this promotion mode should be promoted not only in Beijing and Shanghai, but also in more important cities across the country, so that the fire in art cinema can start a prairie fire and we look forward to a new spring in art cinema, China.

　　　　Hepatitis B is one of the infectious diseases with the highest incidence rate in China, and its mortality rate ranks among the top three reported infectious diseases in China. There are about 120 million hepatitis B virus carriers in China. The annual direct medical expenses for liver diseases in China are as high as more than 100 billion yuan. The incidence of hepatitis B in our province is also on the rise, and the incidence of hepatitis B is higher than the national average. The epidemic of hepatitis B is seriously endangering public health. Hepatitis B can be prevented, but the public doesn’t know enough about it. Therefore, it has become the unshirkable responsibility of the whole society to popularize the knowledge of hepatitis B prevention and improve their self-care awareness and self-protection ability.

　　　　How big is the source of hepatitis B infection in China?

　　　　On September 3, the reporter learned from the Provincial Center for Disease Control and Prevention (hereinafter referred to as the "Provincial Center for Disease Control and Prevention") that China has a large population and is a high-prevalence area of hepatitis B (hereinafter referred to as "hepatitis B"), and about 120 million people are carriers of hepatitis B virus. Among the hepatitis B virus carriers, about 20 million to 30 million people are chronic hepatitis B patients. Every year, about 300,000 people die from liver diseases related to hepatitis B virus infection, such as severe hepatitis, cirrhosis and hepatocellular carcinoma. In recent years, the incidence of hepatitis B in our province has also shown a gradual upward trend, and the incidence of hepatitis B is higher than the national average. From January to July this year alone, the incidence of hepatitis B ranked first in the number of legally reported infectious diseases in our province. From January to July this year, the incidence of hepatitis B in the province was 1248 cases, 785 cases, 1423 cases, 1225 cases, 1205 cases, 1237 cases and 1393 cases respectively.

　　　　According to experts from the Provincial Center for Disease Control and Prevention, the source of infection of hepatitis B virus mainly comes from acute and chronic hepatitis B patients and hepatitis B virus carriers. Hepatitis B virus mainly propagates in human liver cells. Hepatitis B virus is also propagated in other organs and tissues of human body, such as endothelial cells, kidneys, white blood cells, pancreas, muscles and germ cells (referring to sperm) on the inner surface of small blood vessels, and a small amount of hepatitis B virus is found in muscles (smooth muscles) on intestines. Therefore, hepatitis B patients and hepatitis B virus carriers can’t supply blood, and their organs are not suitable for donation after death, because their organs all carry hepatitis B virus.

　　　　The expert went on to say that the main ways of hepatitis B transmission include blood transmission, mother-to-child transmission and sexual transmission. Once hepatitis B virus enters the damaged skin mucosa, it can cause new infection. Mothers who are carriers of hepatitis B virus or patients with acute or chronic hepatitis B can spread to their own children in the fetal period, perinatal period and infancy. Experts estimate that 30%-40% of hepatitis B virus carriers in China originate from the spread of such mothers. This infection is very dangerous and serious. Because 90% of infected people can become hepatitis B virus carriers. The relationship between hepatitis B virus and liver cancer is very close, especially familial liver cancer is mostly related to hepatitis B virus infection. The mother is a carrier of hepatitis B virus, and most of her children are infected in childhood and become carriers of hepatitis B virus. It takes about 30-50 years for hepatitis B virus carriers to develop into liver cancer. Once infants and young children are infected with hepatitis B virus, they will become the main population with liver cancer in the future. Therefore, the first dose of hepatitis B vaccine must be given to the baby within 24 hours after birth in order to effectively block the infection of hepatitis B virus.

　　　　What are the clinical symptoms of hepatitis B?

　　　　According to experts from the provincial CDC, the average incubation period of hepatitis B is 6 weeks, but it may be as long as 6 months. Children are often asymptomatic after infection. But compared with adults, most children can become carriers of hepatitis B virus. Symptomatic hepatitis B patients will feel weak, have stomach upset and other flu-like symptoms, and also have dark urine color or grayish white feces, common jaundice (yellow skin or yellow sclera), and the symptoms can last for weeks or months. Most adults can fully recover from acute hepatitis B virus infection, but many children will become hepatitis B virus carriers. Patients with acute hepatitis B have lifelong immunity to the disease after rehabilitation (without becoming chronic carriers). If there are unexplained symptoms such as burnout, fatigue, loss of appetite, liver pain, hepatomegaly, tapping pain in liver area, jaundice, dark urine color, etc., liver disease examination and hepatitis B serological test should be done.

　　　　How to prevent hepatitis B

　　　　According to experts from the provincial CDC, two measures can be taken to prevent hepatitis B? Don’t use blood and blood products that haven’t been tested for hepatitis B in life and collective environment as much as possible, don’t go to black dens to donate blood, don’t have homosexual behavior and whoring behavior, don’t use unclean syringes, acupuncture needles, dental drills and endoscopes and other interventional medical instruments, and don’t share razors, ear needles, tattoo needles, toothbrushes and other instruments. In addition, it is to inoculate hepatitis B vaccine to improve its own immune antibody level.

　　　　Hepatitis B vaccine is suitable for all people.

　　　　Who is suitable for hepatitis B vaccination? According to experts from the provincial CDC, hepatitis B vaccine is also the only vaccine that can prevent liver cancer. Vaccination of hepatitis B vaccine is the core strategy to prevent hepatitis B. In addition to neonatal immunization, preschool children, adults and high-risk groups of hepatitis B should be vaccinated with hepatitis B vaccine.

　　　　He said that the first group of people is newborns, which is the most important group to receive hepatitis B vaccine immunization. Because if you are infected by hepatitis B virus during this period, 90% of you can become asymptomatic infected and hepatitis B virus carriers, and the consequences are very serious. 30% of liver cancer related to hepatitis B virus infection comes from hepatitis B virus infection in newborns, and a large proportion of them develop into chronic hepatitis. Therefore, neonatal immunization is the most important thing to prevent hepatitis B. Since 2003, our government has provided free hepatitis B vaccine for newborns, and stipulated that all newborns must receive hepatitis B vaccine immunization, which is the right of children and the obligation of parents.

　　　　The second group of people are children under 6 years old. Infants infected with hepatitis B are easy to become carriers of hepatitis B virus. The younger the infection age, the greater the probability of persistent infection. After such children are infected with hepatitis B virus, 30%-70% of them can also become carriers of hepatitis B virus, and they will easily develop into chronic hepatitis, cirrhosis and liver cancer in adulthood.

　　　　The third group of people are doctors, especially doctors in surgery, obstetrics and gynecology, dentistry and otolaryngology, laboratory workers engaged in serum testing and all nurses. Anyone who has not been infected with hepatitis B virus should be vaccinated. Besides protecting yourself, it can also protect the safety of patients. In addition, if there are hepatitis B patients or hepatitis B virus carriers at home, their family members should be vaccinated against hepatitis B to avoid infection.

　　　　The fourth group of people are those who are engaged in heavy physical labor and are easy to cause labor injuries.

　　　　The fifth group of people is people with low immune function. For example, after tumor surgery, people who take immunosuppressive drugs for a long time, renal dialysis patients, and blood patients who often need blood transfusion and blood products are in poor health and have low resistance. Once they are infected with hepatitis B virus, the consequences are very serious, so they should be vaccinated with high doses of hepatitis B vaccine.

　　　　The sixth group of people are the army, college students of certain majors, etc. However, there are also some people who can’t get hepatitis B vaccine and don’t need it. If a person with a fever can’t be vaccinated, wait until his fever has gone down. Secondly, people with allergies, that is, people who are allergic to many things should use hepatitis B vaccine with caution. There are already protective antibodies in the body, and people with high levels do not need to be immunized again. However, if the antibody level is very low, it is still a suitable target for vaccine immunization.

　　　　Three needles, protect the child’s life!

　　　　On September 3rd, the reporter learned that according to the actual situation in our province, the Provincial Health Department, in cooperation with the China Hepatitis Prevention and Treatment Foundation, will give free hepatitis B vaccine to 500,000 school-age children in Haidong, Haixi and Yushu from September this year to May next year, so that more than 95% of school-age children in primary schools in the province can get free hepatitis B vaccination, thus making Qinghai one of the provinces that have completed hepatitis B vaccination for school-age children nationwide. Therefore, experts from relevant departments in our province especially remind the public that hepatitis B can evolve into chronic hepatitis, cirrhosis and liver cancer, and hepatitis B vaccine can indirectly prevent liver cancer. Therefore, after three shots of hepatitis B vaccine are given in newborns and childhood, chronic hepatitis, liver cirrhosis and liver cancer can be prevented. After the child is born, he should be given three injections according to the procedure of 0, 1 and 6 months stipulated by the national immunization plan, that is, the first injection should be given within 24 hours after birth, the second injection should be given at one month and the third injection should be given at six months. Adults and children can be vaccinated according to the procedures of 0, 1 and 6 months, which can protect you and your child’s life. (Author: Wang Xiaohong)

　　The State Council Joint Prevention and Control Mechanism held a press conference on the afternoon of December 20th, inviting experts from immunization program, virology, respiratory and infectious diseases, children’s health and other fields to attend, introducing the medical services for key populations. Pay attention together!

—— About the treatment of illness—

　　Is it necessary for people to use COVID-19’s specific drugs, and can they take them by themselves?

　　Several antiviral drugs were recommended in the ninth edition of the diagnosis and treatment plan, including monoclonal antibodies, nematvir, and azvudine added later. The early use of these antiviral drugs may reduce the occurrence of severe diseases, shorten the course of disease and shorten the time of virus detoxification.At present, these three antiviral drugs are still emphasized to be used in medical institutions and under the guidance of doctors. In particular, monoclonal antibodies need to be administered intravenously and used during hospitalization, which is not suitable for use in outpatient clinics or at home.Naimatevir is a small molecule antiviral drug, which can effectively reduce the risk of severe illness, and the indications are mild and common.When using, we should pay special attention to the interaction between drugs. Some drugs, such as simvastatin and amiodarone, which are being used by the elderly with basic diseases, can’t use drugs such as nimatvir.Therefore, it is emphasized that this drug should also be used under the guidance of a doctor. Azvudine is also a small molecule antiviral drug, which is used to treat AIDS. It is found that it can shorten the course of disease, reduce the virus level and improve symptoms during the treatment in COVID-19, so it is also approved for marketing and can be used in COVID-19. Similarly,This drug also has some precautions, including that pregnant women can’t use it.,Use with caution if there is severe or moderate liver and kidney damage.Therefore, it is emphasized that it should be used under the guidance of a doctor.

　　What are the taboos in the use of common drugs after infection?

　　Generally, after being infected with Covid-19, people use more drugs called symptomatic drugs, that is, they have fever and general pain, and use some antipyretic and analgesic drugs. If you have sore throat, cough and expectoration, and gastrointestinal symptoms, use some corresponding symptomatic drugs. Some are prescribed by doctors, and some may be purchased by themselves.We must be optimistic about the instructions, dosage, frequency of use and other precautions.Some medicine,For example, acetaminophen is a commonly used antipyretic and analgesic, and its contraindication is that patients with severe liver and renal insufficiency should be banned.. For example, there are some people,People with recurrent digestive tract ulcers and bleeding, pregnant or lactating women or people who are allergic to certain antipyretic and analgesic drugs should also be cautious.. When you are advised to use these drugs again,Don’t drink alcohol or alcoholic beverages.. I hope that when you use these symptomatic drugs,Try to use simpler medicine.Because different drugs may sometimes interact with each other, which may increase the potential adverse side effects. There are also patients who have this tendency. In order to control the symptoms quickly, it is not recommended to double the dosage of the drug.Because doubling the dosage of the drug may not be effective, but it increases the burden on the liver and increases the side effects.Some Chinese patent medicines or soup medicines can also improve symptoms and have a certain rehabilitation effect. You can also choose them.

　　It is not recommended to cover the sweat to reduce the fever of the baby.

　　In fact, acetaminophen is the only antipyretic drug that children from 2 months to 6 months can choose. Children under 2 months cannot take antipyretics orally.Therefore, it has always been suggested that babies under 2 months, including newborns, must be sent to the hospital in time if they have a fever, so that medical staff can help the children.

　　It is not recommended to give a baby a fever by covering his sweat.The reason is that the development of baby’s thermoregulation center is not perfect, and skin heat dissipation is a very important way to reduce fever. If these children are covered with too many clothes or covers, they will have no way to dissipate heat through the skin. In the case of heat, their body temperature may be higher and higher, even reaching more than 40 degrees, which is not uncommon in clinic.And some children may have severe heat syndrome.Serious complications such as respiratory failure, dehydration, nervous system injury and even life-threatening may occur. Therefore, when these children have a fever, in addition to the help of medical staff,We should try our best to create a relatively cool and ventilated environment for children and reduce clothing appropriately to improve their comfort..

　　What should parents do if the child has febrile convulsion?

　　Febrile convulsion is a very common emergency in pediatric emergency. Respiratory infection caused by virus is the most common cause of febrile convulsion in our children.The age of children mainly involved is between 6 months and 5 years old, which usually occurs in the first 24 hours of fever, especially in the period of rapid temperature rise, and febrile convulsions are most likely to occur.Under normal circumstances, the child’s body temperature may reach above 38.5 degrees. Children with febrile convulsions usually show stiff limbs or shaking, clenched teeth, tilted eyes or upturned eyes, which may be accompanied by cyanosis of the lips. At this time, there may be no response to external stimuli. In the event of febrile convulsion, parents are advised to do the following.

　　First,Lay the child flat on a flat bed, table or floor.Don’t have sharp things around you, mainly to prevent the child from falling and secondary injury during the seizure.

　　Second,You can unbutton your child’s collar and keep his respiratory tract unobstructed..

　　Third, you can tilt your child’s head to one side. If possible,Keep the child lying on the right side,In case the child vomits, aspiration will lead to suffocation.

　　In the whole process, remind parents that there are several things not to do. First of all,Don’t put anything in your mouth when the child has a seizure., including spoon handles, chopsticks, fingers of adults, etc., because this may cause damage to children or adults themselves. Second, during the seizure,Don’t feed your child anything, including medicine and water.. Third, during the seizure,Don’t try to bind the child’s limbs.Don’t let his limbs twitch, because this may cause secondary injuries to his limbs. Fourth, so far,There is no evidence that pinching people can shorten the seizure time of children.On the contrary, parents may be particularly nervous and exert too much force during the seizure, thus causing soft tissue damage in this part of the child, so parents are not advised to pinch their children.

　　When the child has convulsions,To reduce unnecessary stimulation.. In general,The duration of children’s febrile convulsion is 3 to 5 minutes, and it can stop by itself. When the convulsion stops, the child can be sent to the hospital as soon as possible.However, if the child has had a state of convulsion in the past, or this episode has been more than 5 minutes, then in this process, the possibility of the child’s convulsion stopping on its own will be relatively small. Parents are advised to send the child to the hospital as soon as possible.

　　For the vast majority of children, febrile convulsions will not affect the development of the nervous system and will not leave behind sequelae of the nervous system, so parents need not worry too much.At present, there is no evidence that taking antipyretics in advance has a preventive effect on children with a history of febrile convulsions. At the same time, because the child’s body temperature rises very quickly, there is basically no way to prevent the occurrence of febrile convulsions.

　　Patients with chronic obstructive pulmonary disease should go to the hospital for further diagnosis and treatment after they are infected with COVID-19.

　　Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease in China. The common symptoms of patients are cough and expectoration, sometimes accompanied by dyspnea, and often upper respiratory tract infection leads to the aggravation of the original symptoms. So when should I go to the hospital for further treatment? The first rule isContinue to have a fever, take conventional antipyretic and analgesic drugs, and the body temperature will not drop for more than two days.; The second isThe patient has listlessness, lethargy, listlessness and even unconsciousness, or some signs, such as cyanosis of the lips and edema of the lower limbs;The third isThe patient developed dyspnea, shortness of breath, wheezing,If the breathing frequency exceeds 30 beats/min, this is a sign of shortness of breath; Fourth, if there is a home percutaneous oxygen saturation monitor,Monitoring indicates that the patient’s oxygen saturation is ≤93%.It also suggests that there may be hypoxia; Fifth, after using some emergency drugs, such as bronchodilators, the symptoms of patients are not relieved or further aggravated; Sixth, patients with other symptoms, such as severe gastrointestinal symptoms, inability to eat, weakness, inability to walk, etc., all need to go to the hospital for further treatment.

　　How should patients with respiratory diseases be treated at home once they are infected with COVID-19?

　　If patients with chronic respiratory diseases have COVID-19, first of all, don’t panic, have a normal rest, drink plenty of water, eat balanced and digestible foods such as vegetables and fruits, and so on. Second, do some symptomatic treatment, such as fever, body aches, sore throat, cough, expectoration, etc., that is, take analgesics or drugs to treat sore throat, cough and phlegm. After all, patients with respiratory diseases are people with basic diseases, so they need to monitor their symptoms at home, especially cough, expectoration, shortness of breath and dyspnea. Third, some respiratory symptoms sometimes get worse during infection, even if it is common flu, common cold or virus infection. At this time, some symptomatic drugs should be used first.For example, if the symptoms of dyspnea and dyspnea get worse at once, first use some short-acting bronchodilators for emergency treatment. You can spray 1-2 inhalations at a time, and then inhale 1-2 inhalations every 20 minutes, with no more than 6-8 inhalations in the first hour.. If the symptoms gradually improve or stabilize through this symptomatic treatment, you can continue to observe the symptoms at home. If the symptoms change further, you can go to the doctor again. Fourth,Routine medication must be adhered to.. Fifth,To monitor oxygen saturation at home in time,Know whether the condition has changed in time.

About vaccination—

　　What do you think of the saying that "it is better for young people to be vaccinated than to be infected with Omicron"?

　　Although the pathogenicity of Omicron strain which is popular at present is weakened compared with other variants which were popular in the past. However, after being infected with Omicron mutant, there is still the risk of serious illness and death.This risk of serious illness and death will be reflected at all ages.It’s just that the risk of serious illness and death of the elderly, which we emphasized in the past, will be higher in the whole population. In addition, the proportion of people with basic diseases will be higher.

　　At present, many studies have shown that,Compared with those who have completed the whole course or strengthened immunization with Covid-19 vaccine, the risk of hospitalization or severe illness and death of those who have not been vaccinated is quite different, including young people and adults. If this risk exists to a certain extent, it can be reduced by vaccination. Therefore, it is suggested that those who have not been vaccinated should be vaccinated, and those who have not completed the enhanced vaccination should complete the enhanced vaccination as soon as possible.Whether it is the elderly, adults or young people, the risk is reduced to a relatively low level..

　　Can people who have recently recovered from infection be vaccinated with COVID-19 vaccine?

　　If Covid-19 has been confirmed recently,Covid-19 vaccination is not recommended in the near future.. At present, the immune protection produced by simple infection is not as strong as the mixed immune protection produced by infection and vaccination, so if vaccination is needed in the later stage, it is recommended to vaccinate. How long is this interval? According to the current technical guidelines for vaccination in Covid-19,If Covid-19 is diagnosed, the time between infection and Covid-19 vaccination should be more than 6 months.Of course, our immunization strategy will be continuously improved and adjusted with the understanding of diseases, vaccines and the need for disease control.

　　Can cancer patients be vaccinated with COVID-19 vaccine?

　　As for cancer patients, due to illness and chemotherapy, the immunity of some people will be low, which will increase the risk of serious illness and death. So, in this case,These patients need to be vaccinated with Covid-19 vaccine to be protected, and they are also among the priority groups for vaccination..

　　The clinical manifestations of cancer are actually varied, and the treatment process is also very complicated.Whether cancer patients who are in the onset or in the treatment stage can be vaccinated depends on the judgment of relevant professionals.. Because of the low immune function, the immune protection reaction of cancer patients after vaccination with COVID-19 vaccine may not be as strong as that of healthy people. In the "Work Plan for Strengthening Vaccination in Covid-19 for the Elderly", it is also specifically mentioned that "all localities should scientifically evaluate contraindications, and the specific reasons for those who do have contraindications should be clarified one by one", which is also applicable to the current evaluation of contraindications for cancer patients.

　　It’s been a long time since the whole immunization was completed. Is it still useful to carry out intensive immunization now?

　　After vaccination in Covid-19, there is a protective effect, one is to produce antibodies, the other is to produce cellular immunity and immune memory. After vaccination, the antibody level will decrease with the passage of time. In addition, with the variation of the virus, the immune escape is also enhanced, which further weakens the role of antibodies. But,Cellular immunity, especially in preventing severe illness and death, plays a lasting role..

　　Studies have shown that,Vaccination with booster needles can arouse the immune memory cells of the body on the one hand, and improve the antibody level on the other hand, further consolidating the preventive effect on severe illness and death.. Therefore, it is emphasized that those who have not completed the booster immunization should complete the booster immunization as soon as possible in accordance with the provisions of the immunization program as long as they meet the vaccination conditions.

About strain variation—

　　If a new mutant appears, there is still the risk of reinfection.

　　Now we are infected with BF.7 and BA.5.2,If a new mutant appears, there is still the risk of reinfection.. At present, from the data,The risk of reinfection or reinfection of Omicron strain is higher than that of the original strain, including higher than Delta and the original strain.. Judging from the time when the secondary infection appears, there is usually an interval, and it will not be said that it will be reinfected soon after infection.The probability of reinfection of the same strain is extremely low. Even if infected, there will be no obvious symptoms, which are generally mild.. Secondary infection mainly refers to the breakthrough infection of mutant, and the time interval of breakthrough infection is closely related to clinical manifestations. The shorter the interval, the lighter the symptoms, and the more severe the symptoms after the interval, which is directly related to the antibody immunity in the body. A study in Sweden also found that,After being infected with Omicron strain, the symptoms of secondary infection or tertiary infection with different strains in Omicron are very mild, and they are basically asymptomatic infected people or mild cases..

　　Of course, we should also pay attention to some elderly people. For example, we have done a study on American veterans. Among the elderly veterans, after the second infection, some patients do get worse or even die.Therefore, despite the infection, after the emergence of a new virus epidemic strain, personal protection should be done, especially for the elderly and those with basic diseases.In addition, it is very clear that vaccination in Covid-19 can effectively reduce the risk of severe illness and death. A study in Italy found that vaccination can reduce the incidence of secondary infection and reduce the probability of hospitalization after infection. So,The elderly and those with basic diseases should also emphasize vaccination..

　　What is the pathogenicity of BQ.1 and XBB strains, and will it trigger a new round of epidemic in China?

　　BQ.1 and XBB are new branches of variation in Omicron. Internationally, it has been gradually shown in some European and American countries that they are dominant strains.The main manifestation is the increase of transmission ability and immune escape ability, but its pathogenicity is not obviously different from other series of variants in Omicron.The severe illness rate and mortality rate have not increased significantly in these countries where BQ.1 and XBB are prevalent.In recent three months, BF.7, BQ.1 and XBB have been detected in China.A total of more than 130 subfamilies from Omicron were imported into China, and these 50 subfamilies caused related local cases or outbreaks.The whole BQ.1 and XBB have not yet formed a dominant communication in China (at present, BA.5.2 and BF.7 are still the main ones).However, its propagation advantages will gradually increase, and it may form a common cycle with BA.5.2 and BF.7, as well as other sub-branches with more than 50 inputs.

　　The prevention of BQ.1 and XBB is actually the same as other Omicron mutants, that is, to monitor whether its pathogenicity has changed or not, and whether its genome has further variation. If its clinical characteristics have changed, we will link it with the genome characteristics for judgment.However, there is no report that BQ.1 and XBB cause serious illness and death at home and abroad..

　　It is less likely that a highly contagious and highly pathogenic strain will appear.

　　From the appearance of Omicron in November 2021 to December 18, 2022,There are 709 sub-branches in the world, which have evolved from the five branches of BA.1 to BA.5., including recombinant strains, there are 72 strains produced by recombination between these subfamilies, and XBB is one of these 72 strains. Therefore, the variation of Omicron will continue. As long as it circulates in the crowd, it will replicate, and replication will mutate. The genetic variation of the virus itself may lead to the change of some antigenic epitopes and increase its immune escape ability. So the variation trend in Omicron is,Those with strong immune escape ability are dominant.. Immune escape makes people susceptible to this strain, even if its spreading power is not enhanced, its spreading advantage will still increase.

　　Will it increase its spreading power and lethality? This possibility is relatively small.The cases of hospitalization, death and severe illness caused by Omicron were significantly lower than those caused by early Delta strain and other VOC variants. Therefore, no significant increase in severity and death was observed throughout more than 700 branches.Therefore, on the whole, it is less likely that the pathogenicity will increase significantly. It is even less likely that it will have a more infectious and lethal strain. Nowadays, people have obtained a certain degree of immunity through vaccines or natural infections, which has good protection for people. Even if the virus mutates again, the risk of transmission will increase unless some subversive recombination leads to complete immune escape, but this possibility is relatively small.Therefore, on the whole, it is unlikely that there will be strains with high infectivity and high pathogenicity.

　　What are the monitoring methods for epidemic mutant strains in China at present?

　　After the optimization of the national COVID-19 epidemic prevention and control strategy, China CDC Institute of Virology formulated the Work Plan for Monitoring Covid-19 Mutant in Chinese Population according to the co-circulation of several Covid-19 subtypes in China. Scheme requirementsChoose three cities in each province and one sentinel hospital in each city. Each sentinel hospital takes samples of 15 emergency cases, 10 severe cases and all deaths every week for genome sequencing and analysis, and uploads the sequencing data to CDC Virology Institute in China within one week, and we establish the national Covid-19 genome database.. Through the implementation of this scheme, the epidemic dynamics of Covid-19 Omicron series mutants in China and the composition ratio of each subtype can be dynamically monitored in real time, and new mutants with potential biological characteristics change, including clinical manifestations, transmission power, pathogenicity and so on. It provides scientific basis for vaccine development and diagnostic reagent evaluation (including nucleic acid and antigen, etc.).

-other-

　　How to treat the saying that "Erwin Engst is good early"?

　　Although Omicron is highly contagious, most of it is self-limited after infection, and its pathogenicity or severity is relatively low, butIntentional infection is not advocated or recommended.. Also emphasize that,The elderly, those with basic diseases, especially those who have not been vaccinated, must be well protected from infection in the first round of epidemic peak.. At this epidemic peak, there may be problems of uneven distribution of medical resources or a run, which will lead to the failure of timely and effective treatment for critically ill patients. We still hope that these elderly people will be well protected, including those in nursing homes and those who are bedridden with basic diseases. Everyone should pay special attention to avoid infection. At the same time, those who have not been vaccinated will continue to be vaccinated.

　　At the stage of the first round of rapid epidemic growth, with the passage of time, the number of infected people will increase, and the rapid upward trend will slow down, which is a universal law. But,After a period of time, with the extensive development of large-scale social activities, including Spring Festival travel rush or various social activities, there may be a new round of epidemic. The wave appearance of this epidemic may eventually form a certain group immune barrier, and the incidence rate will drop significantly..

　　What are the criteria for judging COVID-19’s death at present?

　　Different from the epidemic situation in Wuhan in early 2020, most patients died of respiratory failure in COVID-19 at that time. Now, after Omicron virus infection, the proportion of pneumonia in upper respiratory tract and lower respiratory tract is relatively low, and some patients have pneumonia, but the cases leading to respiratory failure are rare. As seen from clinical practice,At present, the main cause of death after Omicron virus infection is basic disease, and respiratory failure caused by Covid-19 infection is rare..

　　In order to reflect the deaths caused by the COVID-19 epidemic scientifically, objectively and realistically, National Health Commission recently organized experts to demonstrate and issued a notice, clearly classifying the related deaths scientifically. Mainly in two aspects,Pneumonia and respiratory failure caused by Covid-19 are the primary diagnosis of death, which is classified as death caused by Covid-19 infection.; Death caused by other diseases and basic diseases, such as cardiovascular and cerebrovascular diseases and myocardial infarction, is not classified as death caused by COVID-19. In order to better standardize the judgment of death caused by COVID-19 epidemic, it is required to adopt the way of consultation and death case discussion to finally judge whether the patient died of COVID-19 or other basic diseases.

Starting from 170,000, 650km battery life +800V+ lidar! This BYD is chosen like this

2025年2月16日 | admin | D4

Before, we talked about how to buy BYD Seal 07 DM-i model and how to choose the most suitable configuration model. So today, let’s talk about how we should make a choice in the pure electric version of the new BYD seal.

How to choose the power?

In terms of the new BYD seal, a total of four models were launched, with the price of 175.8-239.8 million yuan, with three kinds of power and three kinds of battery life.

Among them, the entry-level model is equipped with a 170kW single motor, which has a pure battery life of 510km and an acceleration of 6.5 seconds per 100 km. On the top model, it is equipped with a 390kW dual-motor system, with a pure battery life of 600km and an acceleration of 3.8 seconds per 100 km.

Then, in the middle of the two configuration models, it is equipped with a single motor of 230kW, and it has a battery life of 650km and an acceleration of 5.9 seconds per 100 km.

It’s very simple. If you don’t have too many requirements for battery life and power, but just want to use it for daily transportation and occasionally travel in the countryside, you can consider the entry-level model. And if you want to be better satisfied with power and endurance, and can cope with the use of more scenes, the power in the middle will inevitably be a better choice. On the contrary, you have a high pursuit of power, and if you prefer to enjoy intense driving, those motor-powered top models will be very good partners.

What are the highlights of the new car?

Before making a choice, let’s take a look at the highlights of the new BYD Seal as a redesigned model.

In the design part, the whole car also continues the family-style design, and the biggest change in appearance lies in the brand-new luminous logo on its tail, and the laser radar with watchtower layout is added above the front windshield, which can realize high-speed+urban intelligent driving and reach L2+ driving assistance level, filling the shortcomings of seals in intelligent driving. In addition, the new car adds sky purple appearance color matching and a new style of wheels.

As for the interior part, the "Sardinia Orange" color scheme and a brand-new steering wheel style are added, and the luminous geometric pattern is also equipped in the co-pilot position, which enhances the luxury inside the car. It is worth mentioning that the car is based on BYD e platform 3.0 Evo, and the overall dynamic response and charging efficiency will be improved. For example, it takes only 25 minutes to charge from 10% to 80%.

Which configuration is more suitable?

510 standard edition

Price: 175,800 yuan

Recommended index: ☆ ☆ ☆ ☆.

Let’s look at the entry-level model first. Its overall configuration is quite rich. It is equipped with 18-inch rims, 360 panoramic images, LED matrix headlights, panoramic sunroof, 15.6-inch central control panel, 5G car networking system, 60W wired charging, 50W mobile phone wireless charging, front seat heating/ventilation, L2 DiPilot driver assistance system and so on.

However, it should be noted that this is the only model in the whole system that does not support the 800V platform, so its maximum power for fast charging is only 180kW.

Generally speaking, the pure electric model has a higher threshold, so even the entry-level model has a higher configuration, which is basically equal to the mid-range or even high-range model of the plug-in model, and the configuration in some aspects is even richer. So if you just want to use the vehicle as a means of transportation, it is still a good choice.

650 long battery life version

Price: 189,800 yuan

Recommended index: ☆ ☆ ☆ ☆ ☆.

The price has increased by 14,000 yuan, and the car has a 650km battery life. In this version of the car, you can get 19-inch rims, electric induction trunk, trunk position memory, rear privacy glass, rearview mirror reversing automatic rollover, rearview mirror memory, simulated sound waves, car KTV, driver’s seat memory, interior atmosphere lights, and 12-speaker Dana audio. Starting from this configuration, you can also choose silver-plated EC intelligent light.

In addition, the most important thing is the performance of power. For example, the motor power is increased from 170kW to 230kW, the battery capacity is 80.64kWh, and the pure battery life is increased from 510km to 650km. Moreover, from this configuration, an 800V high-voltage platform is installed, and the charging power is also increased from 180kW to 230kW.

Compared with the former, the models with this configuration are obviously much richer in terms of convenience, technology and some playability configurations, especially the endurance of 650km, which can better meet the needs of different scenes. Personally, this configuration is still more recommended.

650 intelligent driving edition

Price: 216,800 yuan

Recommended index: ☆ ☆ ☆ ☆.

The price has increased by 27,000 yuan, and it comes to the high-profile model. It is also equipped with lidar from this configuration.

In terms of details, most of the configurations of this model are basically the same as those of the former. The biggest difference lies in the addition of a laser radar, and at the same time, binocular cameras are used in the front, and the number has increased from 5 to 11. Thanks to the addition of lidar, the car supports intelligent driving in cities and high-speed sections and has the function of traffic light recognition.

In other respects, the steering wheel is changed from leather to leather, and the steering wheel heating, 12-inch HUD head-up display and interior fragrance system are added. In other words, the biggest improvement of this configuration really lies in smart driving. As for whether this 27,000 value is worth it, it depends on how high your demand for smart driving is.

600 four-wheel drive intelligent driving version

Price: 239,800 yuan

Recommended index: ☆☆☆

The price has increased by 23,000 yuan again. The most direct improvement of this model lies in the power, from the single motor rear drive of 230kW to the dual motor four-wheel drive of 390kW, and the acceleration of 100 kilometers has been shortened from 5.9 seconds to 3.8 seconds. But correspondingly, the battery life is adjusted from 650km to 600km with the same battery capacity. At the same time, the model with this configuration is also equipped with i-TAC intelligent torque control system, which will have better performance in handling.

In other parts, the car has been replaced with sports style seats, and the seats are made of suede materials, that’s all. If you don’t have the ultimate pursuit for the power part, then this model may not be a suitable choice for you.

Therefore, among the new BYD Seal models, the most recommended model with the 650km long battery life version is more in line with the needs of mass users, and the price of less than 190,000 is also very reasonable. Secondly, it is recommended to introduce the 510 standard version and the 650 intelligent driving version. The choice of these two models is actually relatively simple. If there is no high requirement for configuration and battery life, it will be more cost-effective to choose the standard version directly, and if you are pursuing intelligent driving, just choose the latter directly.

The editor said:The starting price of 170,000 seems to be slightly high, but in fact, it is reasonable and still quite cost-effective, which is the style that BYD has always been familiar with. Moreover, it is equipped with high-level smart driving on high-profile models, which makes up for BYD’s previous shortcomings in smart driving and narrows the gap with new power brands. As a whole, it is highly competitive. Nowadays, BYD has become a brand that many people can’t avoid buying a car. After that, I believe it will be even more so. In your opinion, will the new BYD Seal become your first choice for buying a car within 200,000 yuan?

Seeing the New Magotan Test Drive from the Business Angle： The New Magotan 2.0T

2025年2月12日 | admin | A1

Experience: The dynamic performance of the new generation 2.0T is still the same, and the extended sports performance is limited.

　　Except for the higher 3.0, the new generation of Magotan has not been listed yet, and other power sources have remained basically the same. How will the 2.0T new Magotan look at its performance from the eyes of bosses? Let’s take a look.

　　This powertrain can be described as an "old friend". Although there is still a higher-level 3.0FSI powertrain version that has not been released, the 2.0+6 powertrain will definitely not disappoint you in business-class models.

　　This 2.0T model is quite smooth in D-gear mode. After the throttle is slightly slow, the power will be output very smoothly, which is not in a hurry, but it is definitely not a feeling that can’t be used, as long as you are willing to give oil. However, when the S gear is engaged, the new Magotan will be restless, and DSG will drop two gears in a row, which is followed by a strong push-back feeling, and the power output is extremely sharp. However, for leaders who are used to comfortable riding, D-block driving is what they want.

　　The chassis adjustment of the new generation of Magotan tends to be comfortable, but it is still soft, which can better filter the vibration on some bumpy roads like shock absorption belts. This kind of "softness" is the best comfort for the boss.

　　Although the power and chassis adjustment are thinking about the business car that bosses want, the noise reduction that bosses value very much seems to have not made much progress on the new generation of Magotan, which makes bosses start to be a little embarrassed. Magotan can do better in noise reduction.

Supplementary track test drive:

　　Next, we will supplement the test drive experience of the new generation of Magotan in the test site to see how much the extended 100mm wheelbase will change the control of the new generation of Magotan.

　　Through the test drive, we can clearly feel that the poor braking posture of the old Magotan still does not perform well on the new generation models. The new generation of Magotan’s soft adjustment and extended wheelbase make it easy to reach the limit in fierce driving. The suspension is easily compressed to the limit and often involved in work. This is the "disaster" caused by the 100mm extended wheelbase. The new generation of Magotan continues to stay away from sports.

Full text summary:

　　There is no doubt that the new generation of Magotan with longer wheelbase has brought you a brand-new ride experience in the back row. Although it has affected the performance, this compromise is still worthwhile. For those who emphasize business performance, the main consumer groups are elites who are slightly older. For them, the motivation performance is decent enough. As for manipulating these, it is no longer important. From this perspective, the new generation of Magotan does have the capital to meet the needs of these people. (Text, picture, photo/He Yongming)

Prospect of 2023 Munich Auto Show： European brands versus independent new energy sources

2025年2月4日 | admin | C3

　　Lead:The 2023 Munich Auto Show will be held in Munich, Germany on September 5, when dozens of vehicle brands will participate, and more than 30 new cars will be unveiled, including some new energy strategic models and product concepts. China brands also include BYD, Zero Run and Aouita, bringing models and technologies aimed at globalization. Of course, European cars are fighting at home, and there must be strategies and models that represent the future that attract attention.

　　However, according to the statistics of Sina Auto, different from previous Munich Auto Show, there are still many models that need new cars to focus on at the 2023 Munich Auto Show, because most car companies bring pure electric or hybrid models, such as BMW Neue Klasse’s brand-new pure electric concept car, Volkswagen GTX, Porsche Cayenne plug-in, zero-run B11 and the third-generation Tiguan, which will definitely be jointly produced. Here are some products worthy of attention from all brands.

　　-A variety of electrification concept models /CLA/ new generation AMG GT

　　In addition to the new AMG GT, EQB and other models brought by Mercedes-Benz at this Munich Auto Show, what people are actually looking forward to are those concept cars, which represent the products of Mercedes-Benz in the era of new energy intelligence and are also the models of future models, including the entry-level luxury concept car, the new E-class All-Terrain, Vision EQXX concept car and Vision One-Eleven concept car.

　　What is more worth looking forward to is the new generation of CLA pure electric model, and its concept model is scheduled to debut at Munich Motor Show, a domestic version of this model. In addition, there are also models that cooperate with domestic car companies, that is, models jointly developed and built with Geely Automobile.

　　Of course, a new generation of AMG GT is indispensable. Although the launch has been completed before, this is the first appearance of the public exhibition. It is based on the new AMG sports car architecture, equipped with a 4.0T V8 engine, and the shape of the mid-net has been changed. The front lights have been changed to daytime running lights consisting of three spots, the active adjustable tail wing has been added to the rear tailgate, and a large area of carbon fiber sports kit and sports exhaust from both sides have been used to surround the bottom.

　　The interior changes are the three-spoke steering wheel, which adopts dragonfly steering wheel and Nappa leather material. All-digital instrument screen is integrated with three-dimensional sun visor, equipped with 11.9-inch central touch screen and built-in second-generation MBUX human-computer interaction system.

　　In terms of power, the AMG 4.0L V8 twin-turbo engine has been optimized. The maximum power of the 55 version is 350kW and the peak torque is 700Nm. Version 63 has a maximum power of 430kW and a peak torque of 800Nm.

　　Comments: In fact, the products brought by Mercedes-Benz are not limited to these. There will also be EQB and a new generation of E-Class Estate crossover models, and the latest electrification progress will be announced. For electrification, Mercedes-Benz will present the biggest change at this Munich Auto Show. What kind of product innovation Mercedes-Benz, as the brand that invented cars, can bring to us, we are very much looking forward to it.

　　BMW’s brand-new pure electric concept car — Neue Klasse

　　BMW Neue Klasse’s new pure electric concept car will be the gene that determines BMW’s future. It is reported that all models built by the new platform will be equipped with cylindrical batteries to adapt to all levels of models, including large SUVs from Series 1 to X7.

　　It is reported that the energy density is increased by 20%, the packaging efficiency is increased by 30%, the cruising range is increased by 30%, the charging speed is increased by 30%, the weight is reduced by 20%, the production cost is reduced by 50%, and the carbon dioxide emission in the production process is estimated to be reduced by 60%. BMW’s battery partners include China’s Contemporary Amperex Technology Co., Limited and EVE.

　　In addition to the battery, BMW Neue Klasse will adopt the sixth generation BMW eDrive electric drive technology, which will be built based on the new architecture of NCAR(New Cluster Architecture), instead of the current CLAR and FAAR architectures.

　　The new technology used in the car is BMW Panoramic Vision. The highlight of its function is that it can project information on the dark coated area on the lower edge of the windshield. Similar to the long-strip AR-HUD, the projected image has better clarity and color performance, and all passengers can see the vehicle status and prompt information.

　　Comments: Compared with Mercedes-Benz’s cooperation with domestic smart electric vehicles, BMW still remains independent. Of course, it can also be reflected from battery suppliers in the planning of developing a new generation of pure electric platform. The integration and development of its new platform still involves domestic strong video suppliers/manufacturers, which is an inseparable link for building cars at present. I only hope that BMW’s models mass-produced through Neuklasse platform will not be too expensive to have stronger competitiveness. Of course, at this year’s Munich Auto Show, BMW also brought a new generation of 5-Series, i5 and brand-new BMW X3 models that have been released before, but their attraction is not as good as this brand-new pure electric concept car of BMW Neue Klasse, which represents BMW’s future.

　　Volkswagen ID.7 series-id.7gtx

　　Volkswagen will bring a variety of ids. Car models, including ID.7 Wagon and ID.Buzz unveiled at Shanghai Auto Show, ID.7 GTX and possibly ID.2all, will further enhance the influence of local Volkswagen brands.

　　The model worthy of attention is Volkswagen ID.7GTX As the world’s first model, it is naturally more amazing than ID.7Wagon. For example, in terms of performance, it will adopt a dual-motor four-wheel drive system, equipped with a dynamic management system to stabilize the control, and also provide different driving modes to limit the adjustment of driving, braking, steering and chassis control, which can essentially balance the energy consumption and dynamic performance of the vehicle.

　　In addition, as a neutral pure electric sedan, and ID. The flagship product of the series, ID.7 GTX, is equipped with top-level equipment. On the technology of IQ.Light, the headlights can adjust 18 high-beam LED light sources in the light group to carry out independent control of different modes, including the light and dark sense sensed by the sensor, and carry out very delicate automatic adjustment function.

　　In terms of appearance, ID.7 GTX and ID.7 maintain the family appearance, and the details use bright black design elements. Not only the black roof paint and dark windows bring two-color body painting, but also the rearview mirror and taillights are blackened, which together bring a stronger sports atmosphere. The rearview mirror and the car have exclusive GTX logo, which highlights the characteristics of high-performance models.

　　Comments: Like the previous 3.0L V6 Passat, the ID.7 GTX pays attention to performance and configuration, but also gives consideration to comfort. It is a high-performance pure electric medium-sized car suitable for long-distance travel. In terms of interior decoration, it should be consistent with the sharpness of ID.7, and it should not change much, and it may pay more attention to the details of interior decoration. For example, the seats, instrument panels and doors will be designed with red GTX contrast stitching and other details.

　　Volkswagen brand-a new generation of Tiguan

　　The third generation Tiguan is coming, which is an important model at the Munich Motor Show. The previous generation Tiguan has been fighting for nearly eight years. What does the third generation Tiguan look like? From the outside of the disguise, there is an ID. The feeling of the series, especially like ID.4, is very round and based on the Volkswagen MQB EVO platform. The length of the known overseas version is 4551mm；; Height is 1640mm；; The width is 1939mm and the wheelbase is 2681 mm. It is estimated that the wheelbase will be lengthened after the joint venture.

　　The third generation model will be launched in Europe in the first quarter of 2024. The low-profile model will be equipped with a 12.9-inch entertainment screen, while the high-profile model will use a 15-inch screen. Same size as ID.7 screen. In addition, there is a 10.25-inch digital dashboard and a new HUD, as well as seats with massage and ventilation functions.

　　In terms of power, the new generation of Tiguan will provide three power sources: gasoline, diesel and plug-in hybrid. The power of plug-in hybrid models is between 201 HP and 268 HP, providing a pure electric cruising range of up to 120 kilometers, which is the first time to use faster AC charging and standard DC charging functions. There will be front-wheel drive and all-wheel drive options for the drive. The most important thing is that this generation of cars should be equipped with dynamic chassis control system, which is called DCC Pro by Volkswagen, but it needs to be installed at extra cost. I don’t know what will happen after the joint venture is made in China.

　　Comments: The third generation Volkswagen Tiguan has been slowly "electrified", and it is possible that this car is the last generation fuel Tiguan model, Volkswagen ID. The series will soon cover all fuel vehicles, and Volkswagen has already bet on electrified routes. I wonder if friends will still choose Tiguan?

　　Porsche cayenne-plug-in Cayenne Turbo S E-Hybrid

　　Compared with the plug-in version of the Cayenne, I actually look forward to the Porsche Macan EV, which is the pure electric version of Macan, but there is no news that this car will be unveiled. Let’s take a look at the plug-in version of the Porsche Cayenne first. It is reported that the name of this car is not Cayenne+PHEV, but Cayenne Turbo S E-Hybrid, which keeps the same naming method as Panamera E-Hybrid.

　　The appearance of the new car is not much different from the current model, but it is slightly different in details. For example, a larger mesh has been replaced, and the aerodynamic suite with strong sense of movement has also increased, and the details of the body have been blackened. It is possible that the front and rear fenders are matched with prominent wheel eyebrows, which has a wide visual effect. The rear of the car is equipped with a double spoiler, and the size of the middle tail row is relatively large, that’s all.

　　The interior is made of a large number of Alcantara materials, and the layout is basically the same as that of Turbo GT. Of course, there will be many options. Therefore, the co-pilot side display screen with media function can realize three-screen interconnection, and it may also be optional.

　　In terms of power, the V8 plug-in hybrid system may be a powertrain shared with the new Urus, with a comprehensive power of over 700 HP, a maximum torque of over 900 Nm, and a top speed of over 300 km/h..

　　Comments: Cayenne and Lamborghini Urus, also born on MLB Evo platform, may only be slightly different in handling and extreme performance adjustment. In other respects, you can buy a cayenne. This car should be worth it, right?

　　Zero Run World First —B11

　　High-profile participation in Munich Auto Show by Zero Run will not only bring a global model B11, but also a more important globalization strategy. This model is a medium and large SUV code-named B11, and this car will be named "Zero Run CX". As a global model, it will be launched in five-seat and six-seat versions, and the power will be available in two systems: extended range and pure electric.

　　At the exhibition, Zero Run will officially launch the newly developed LEAP3.0 architecture, whose core electronic components are self-developed all over the world, taking the lead in truly realizing central integration. The architecture can cover many core modules including smart battery, smart electric drive, smart cockpit, smart driving and so on, and meet the application of all zero-run vehicles with various solutions.

　　Comments: It’s not the first time for a China brand to participate in the Munich Auto Show, but it’s definitely a commendable thing for a rising star to be able to participate in the international auto show with strong self-research ability.

　　Aouita 12

　　Aouita 12, which was supposed to make its debut at Chengdu Auto Show, will make its world debut at Munich Auto Show this time. The length, width and height of Aouita 12 are 5020*1999*1460(1450)mm and the wheelbase is 3020mm, which is also the reason for its debut in Europe. Compared with the dimensions of BMW 5 Series or Mercedes-Benz E-Class, it is larger.

　　In addition to the larger size, the overall design style is more avant-garde, using electronic exterior rearview mirror, equipped with active lifting tail, more low-lying design style, very racing.

　　Aouita 12 will also adopt the newly developed interconnected technology system, which will bring unprecedented intelligent experience to the passengers in the car. From entertainment to information, from navigation to communication, Aouita 12 will bring more extreme sensory and entertainment experience.

　　In terms of power, Aouita 12 will continue to use the three-electric system of Aouita 11, with the rated motor power of 230kW/425kW, and provide two drive versions of two-wheel drive and four-wheel drive version. Aouita 11 has a zero acceleration of 3.98 seconds, while Aouita 12 has a more streamlined body design, with a lower drag coefficient and better dynamic data.

　　Comments: The overall tonality of Aouita brand belongs to the representative of intelligent electric vehicles. The delivery volume of Aouita 11 has reached 1,786 units in July. As a model with high premium capacity, the monthly increase is obvious, which fully shows that the audience of this model has been rolled out, and globalization will become another exhibition window in Aouita.

　　BYD Seal U/Tengshi D9

　　BYD Seal U will be officially unveiled at Munich Auto Show. It is actually BYD Song PLUS Champion Edition (EV) and the sixth model launched by BYD in the European market. In addition, BYD will also display Tengshi D9 model in the European market for the first time, which is also worth looking forward to.

　　Comments: BYD is accelerating its efforts in overseas markets. According to previous media reports, the starting price of BYD Seal U in Europe will be less than 50,000 euros; Tengshi D9, which has performed well in the domestic market, will also be tested in the European market.

　　Summary:The above are some of the new car information we obtained before the Munich Auto Show. Sina Auto will also bring first-hand reports on the scene. At that time, the new models after Opel’s rebranding, as well as many latest models and information such as Tesla humanoid robot, electric motorcycle and Mercedes-Benz concept car will also be presented one by one. Sina Auto will continue to report on the 2023 Munich Auto Show, so stay tuned.
