　　　 On the 22nd, the legendary war of ancient costumes that brought together Cecilia Cheung, Ren Xianqi, Zheng Peipei, and Liu Xiaoqing released the single-person version of the promotional poster starring Cecilia Cheung Ren Xianqi, and at the same time exposed a group of Mu Guiying (Cecilia Cheung) and Yang Zongbao (Ren Xianqi). It is reported that these two sets of military costumes show the changes in the identities of the two before and after marriage. Different styles and types of military costumes carefully analyze the emotional experiences of the two, adding a lot of warm pictures to the film.

Cecilia Cheung and Ren Xianqi Posters Exposed

　　　 As the male and female No. 1 in the film, the film specially designed the single-person promotional posters of Mu Guiying and Yang Zongbao. Similar to the style of the posters of the previously announced series of characters, they all use cool-colored backgrounds. Cecilia Cheung and Ren Xianqi went into battle in military uniforms. Ren Xianqi held a long spear in the poster, full of heroism; Zhang Cecilia galloped on her horse, looking anxious.

　　　 In an interview, the director, Chen Chengqi, revealed that he had deliberately increased the love scene between Mu Guiying and Yang Zongbao in the script, and cleverly combined the theme of "the righteousness of the family and the country" with the theme of the two. The movie’s promotional song "Raising Eyebrows" sung by Zhao Qianyu also fits this love theme and was selected. Therefore, when the film is released, Cecilia Cheung and Ren Xianqi "kiss goodbye" will definitely make many female audiences cry.

Cecilia Cheung and Ren Xianqi are deeply in love, lighting up the literary and opera part

　　　 The film is based on the well-known legend of the "Yang family general". Cecilia Cheung and Ren Xianqi play the classic legendary couple Mu Guiying and Yang Zongbao in the film. Although the main plot of the film is to focus on the interpretation of Yang Zongbao, played by Ren Xianqi, after all the men of the Yang family died in the battlefield, She Taijun led the female general of the Yang family to carry the flag of the Yang family and hold on to the battlefield in the case that the reinforcements could not arrive in time; Mu Guiying, played by Cecilia Cheung, led the battlefield many times to rescue everyone in difficult times. However, in order not to let the audience keep indulging in the tragic emotions of the war, the director revealed that he specially increased the love scene of the Mu and Yang, revealing a little warmth.

　　　 It is reported that in the film, Yang Zongbao leads the Song army to encircle Mu Kechang and meets Mu Guiying. From meeting and knowing each other to staying together, Mu Guiying and Yang Zongbao can be regarded as "happy enemies". The romantic emotional drama is integrated with the point of firmness and toughness, which is interspersed throughout the film, making people see the warmth of the war drama. Director Chen Chengqi also said that "Jackie Chan was also moved by the literary drama after watching the first cut of the film."

Husband and wife photos are exposed to reveal emotional experiences

　　　 In order to show the different stages of the film "Women General Yang", Yang Zongbao and Mu Guiying have two military costumes to match, showing the state of each stage.

　　　 Unlike the earlier photos of military uniforms, this time’s military uniforms divide the storyline in a simple and clear chronological order. The film returns the time to the scene where Yang Zongbao and Mu Guiying first met by flashback montage, and then constantly flashes the sweet and bitter moments they experienced together. The director said that "this scene cannot be regarded as the core of the film, but it is very similar to the relationship of some young people in real life. In fact, it is a very heart-wrenching relationship, and everyone will naturally understand when they see the film."

　　　 Regarding the difference between the two sets of armor, Director Chen also introduced, "When Mu Kezhai and the Great Breaking of the Tianmen Formation, both of them were very young and had not yet married, so Mu Guiying’s armor was brighter in color, embellished with bright yellow and red, and Yang Zongbao’s armor had a white decorative pattern with water patterns. When the two came of age and fought in the Western Xia Dynasty, the metallic color of the armor was heavy, Mu Guiying’s pattern was similar to that of Liu Xiaoqing and other female generals, and Yang Zongbao’s armor used many tiger head patterns to show their mature identities."

"hanging wire for pulse diagnosis" of satellites in orbit

■ Lu Binghong Zhang Mi Liberation Army Daily reporter Wang Lingshuo

On the eve of the Spring Festival this year, Xi ‘an Satellite TT&C Center successfully completed the health status assessment of 52 Beidou navigation satellites. Through the "physical examination" of the Beidou navigation satellites in orbit, the scientific and technical personnel ensure that the key technical indicators of these satellites meet the requirements of providing various services normally and continue to maintain good working conditions in orbit.

The reason for the "physical examination" of satellites is that satellites in the past days will sometimes have "minor ailments and pains" or even "incurable diseases", which will affect business applications and lead to the failure of the whole satellite. China’s space science and technology workers are deeply involved in the on-orbit diagnosis and maintenance technology of spacecraft to realize early detection, prevention, diagnosis and treatment of satellite faults.

Schematic diagram of injecting maintenance instructions on the ground to satellites in orbit

Satellites in orbit are so delicate.

When it comes to space flight, people often think of the rocket launch that attracts people’s attention and rises in flames. In fact, this is only the prelude to the space mission, and the work really begins when the satellite enters the scheduled orbit and is put into business application in space.

Satellites are the largest number of spacecraft launched by human beings, accounting for more than 90% of the total number of spacecraft launched, and have considerable uses in meteorological monitoring, communication and navigation, disaster prevention and mitigation and other fields. As a complex system composed of thousands of components, satellite has more and more functions and greater value with the continuous development of technology. The times of detection, diagnosis, calculation and treatment, control and disposal, and the telemetry parameters that need to be downloaded and monitored are also increasing. This puts forward higher requirements for the accuracy and stability of the ground control system. However, satellite technology is complex and dense, and it is in a complex space environment, so the probability of failure exists objectively and there are various types.

In 2018, shortly after the latest model of meteorological satellite GOES-17 in the United States was put into orbit, the cooling system failed, which made the imaging system of this satellite unable to provide satellite images in near infrared and infrared channels. Satellites can’t get infrared cloud pictures taken at night in time and effectively, and they become "blind" at night.

Coincidentally. In July, 2019, the European Galileo satellite navigation system lost all 24 satellites due to the timing error of the precise timing facilities located in Italy, and the whole system was once paralyzed. It was not until a week later that the system fully resumed service.

At the same time, satellites operate in a vacuum, weightlessness, ultra-low temperature, strong radiation and full of unknown factors for a long time, and space junk and solar activities will bring trouble and even fatal damage to satellites. Therefore, it is inevitable that there will be some technical problems during the life of the satellite.

What’s more, the cost of modern satellites is high, and with the launch cost, the cost of a satellite is often calculated in hundreds of millions of yuan. If the technical failure of the satellite is not eliminated in time or cannot be eliminated, huge economic losses will be inevitable. Therefore, once the running satellite fails, all countries will spare no effort to rescue the satellite and minimize the loss.

Troubleshooting with "Hanging Wire Pulse Diagnosis"

When there is a problem with the machine on the ground, people can locate and eliminate the fault through various methods. For satellites in orbit, it is the only way for technicians to master the attitude and working state of satellites by means of electromagnetic wave transmission.

The so-called satellite fault diagnosis and maintenance means that when the satellite fails, in order to avoid the paralysis or functional failure of the whole system caused by the failure of some components, the state detection, fault diagnosis, health assessment and other work are carried out quickly through telemetry data, the current state and future "illness" trend of the satellite are analyzed, the satellite fault level is defined, the fault location and cause are determined, and the treatment is carried out in time. This is just like the plot of "hanging the wire to feel the pulse" in Chinese classical novels and traditional operas. With this core technology, ground measurement and control personnel can detect tiny faults hidden inside the satellite as soon as possible, and after fault identification and fault isolation, take corresponding maintenance support or fault degradation treatment, so as to avoid catastrophic failures of the satellite and ensure the safe operation of the satellite.

The diagnosis and maintenance technology of spacecraft is developed with the realistic requirements of spacecraft mission expansion, control accuracy improvement and working life extension. The traditional space powers, represented by the United States and Russia, started earlier and have done a lot of research and practice in this field.

In the 1960s, with mankind gradually entering the space age, the spacecraft diagnosis and maintenance technology was also launched. Due to the limitation of technical conditions, component quality and design level at that time, people can only rely on simple instruments to monitor some key parameters of the satellite with single signal threshold state in this period to judge whether there is a fault. This method provides a certain guarantee for the on-orbit operation of early human spacecraft. At this stage, the average life of spacecraft is generally short. In manned space mission, the safety guarantee system of the system is composed of state monitoring, ground expert consultation and astronauts’ direct participation, and the autonomy, real-time and reliability of the spacecraft fault detection system are also poor.

Since 1970s, with the development of technology and the improvement of component quality, design level and process level, the diagnosis and maintenance technology based on hardware redundancy has been widely used in the field of spacecraft. The diagnosis method has also developed from simple threshold judgment to making full use of various dynamic testing technologies, monitoring technologies and information processing technologies, which has greatly extended the average life of spacecraft.

During the Apollo mission to the moon, the United States first established a flight anomaly analysis and evaluation system. The system includes flight fault monitoring and processing, flight state evaluation, flight data standardization, fault ground simulation, etc., and all emergency life-saving parameters are equipped with triple repetitive sensors and dominant voting logic circuits, which obviously enhances the autonomy and reliability of the spacecraft fault detection system.

In the 1980s, artificial intelligence research flourished, and knowledge-based diagnosis and maintenance technology, especially expert system technology, began to be widely used in the aerospace field. Among them, several intelligent fault diagnosis technologies based on expert system and testability model data-driven are the most representative. At the same time, the appearance of highly complex and reusable spacecraft such as the space shuttle makes the fault diagnosis and maintenance system not only have the distribution of modular functions, but also have the integrity of coordination. With the gradual construction and on-orbit operation of the International Space Station, its fault diagnosis and maintenance system has further greater variability, better adaptability and stronger robustness, and gradually develops in the direction of self-management, so that the failed space station can continue to complete its scheduled tasks without affecting its performance.

"Star Shepherd" guards "China Star"

The management level of long-term in-orbit satellites largely determines the realization of satellite efficiency. Since China launched the first artificial earth satellite in 1970s, the spacecraft on-orbit management and control technology has made great progress through the unremitting efforts of several generations of scientific and technological personnel.

As early as 2007, relying on Xi ‘an Satellite Monitoring and Control Center, China began to build a national-level "satellite general hospital"-spacecraft on-orbit diagnosis and maintenance center, and immediately carried out major scientific research projects in the field of spacecraft on-orbit fault diagnosis and maintenance.

With the increasing number of satellites in orbit, China urgently needs to further improve its on-orbit diagnosis and maintenance capabilities. In 2014, Xi ‘an Satellite TT&C Center established China’s first on-orbit fault diagnosis and maintenance laboratory. Through the research on early identification and location technology, on-orbit fault simulation and maintenance technology, on-orbit reliability growth and life extension technology, the independent innovation ability of on-orbit fault diagnosis and maintenance of spacecraft in China was further improved, which promoted the sustainable development of China’s aerospace engineering and became a solid foundation support for the continuous increase of the number of on-orbit satellites in China.

By collecting and sorting out thousands of fault cases at home and abroad and summarizing nearly one million pieces of diagnosis knowledge, the center independently developed an expert system for spacecraft fault diagnosis, which effectively solved the problems of late discovery, slow analysis and difficult positioning of spacecraft micro-faults.

In addition, starting from Beidou satellite, they independently developed a satellite health assessment system, established a relatively complete three-level health assessment index system of "sub-system, key single machine and key performance", put forward a meta-knowledge construction method of health assessment for single satellite in orbit, and built a detailed "physical examination file" for each satellite. The evaluation conclusions of the satellite system put forward targeted countermeasures and suggestions for the follow-up satellite on-orbit management from the aspects of key components’ operation state, abnormal prevention and response, space environment change and load efficiency guarantee, which effectively ensured the safe and stable operation of Beidou system in orbit.

As the largest long-term management center of spacecraft in China, Xi ‘an Satellite TT&C Center has been managing China’s satellites in orbit for a long time, taking on the on-orbit management tasks such as daily telemetry monitoring, orbit control, fault diagnosis and maintenance, and it is a veritable "big housekeeper" of China satellites. Although the "China Stars" are in space, they are not alone, but are always under the care of the "Star Shepherd".

In the future, Xi ‘an Satellite TT&C Center will also deeply and extensively apply artificial intelligence technology, comprehensively improve the level of diagnostic and maintenance capabilities, and lay a solid technical foundation for the on-orbit management of the "giant constellation" in the future.

　　Li Laijin is on his way to deliver takeout.

　　This summer, the number of takeaway orders in Beijing at night has increased by 60% compared with last year. According to data, Changping Huojiaying and Fengtai Minute Temple ranked first and second in the ranking of the most active business districts at night. In addition, in Yanqing District and Huairou District, the number of late-night barbecue orders increased by more than 4 times year-on-year. Behind the surge in the number of orders is every "on-time delivery" of the takeaway brothers. From 9:00 pm to 12:00 pm is the peak period of night takeaway orders. They shuttle through the streets and alleys, adding "dynamic beauty" to the night Beijing.

　　Delivery riders haunt at night "with additional subsidies and no one grabs orders"

　　"Ding Ding", at 10:59 pm, Li Laijin, who was born in 1996, received a new order.

　　From the "7-11" convenience store on Xierqi West Road to the "Contemporary City Home" community about 1.2 kilometers away, the system recommends that riders be delivered within 28 minutes.

　　"Hello sir, sorry for the long wait." After 20 minutes, Li Laijin completed the delivery, which was 8 minutes faster than the time suggested by the system. He just pressed the button to confirm "delivery completed", and the "ding ding" sounded, and the new order came again. Between 9:00 and 12:00 that night, Li Laijin sent out a total of 6 orders.

　　According to data from a takeaway platform, the number of late-night takeout riders born in the 1990s has increased by more than 60% compared with last year. Li Laijin is one of them. The site where Li Laijin works is located in Zhongguancun Software Park. During the day, orders are mostly concentrated in Internet companies, and most of the night orders come from residential areas near Huilongguan.

　　Gu Xiaofang, a 32-year-old female rider at the Wangjing shopping district, also likes to work at night. Gu Xiaofang’s site is divided into three groups. Her group has more than 30 people, and there are six or seven people who work night shifts every day.

　　"There are subsidies, there are few riders, and no one grabs orders at night." This is the main reason why Li Laijin and Gu Xiaofang like to work at night. According to Li Laijin, at the software park distribution station, the courier earns 10 yuan for delivering an order during the day, and there is a subsidy of 2 yuan for each order at night. At Wangjing Station, where Gu Xiaofang is located, in addition to the subsidy for each order, he can get an additional 20 yuan per night. In Gu Xiaofang’s view, the evening is the third time with higher income after the two dining peaks at noon and evening.

　　Mr. Jia, a 31-year-old father of two, runs more night shifts than other riders at the station. "If you run a dozen or so, you can earn 20 yuan more," Mr. Jia said. "I take the initiative to work the night shift until 12 o’clock every day."

　　According to reports, this year, Jia Shaoke has completed a total of 7,923 orders, with an average of 34 orders per day. The rider level has reached Gold 1, and the next promotion level is the most advanced king.

　　Order remarks are varied "Delivery of takeout and handwritten sweet words"

　　Many people like to write notes when ordering. Statistics from a takeaway platform show that from the beginning of 2019 to August 5, among late-night orders between 9 pm and 5 am, riders received more than 560,000 notes asking to buy cigarettes on their behalf. The request to throw garbage on their behalf ranked second, with 9,397; the third order note was somewhat unexpected, asking riders to "draw a picture". In addition, the number of messages asking riders to play games, dance, and tell jokes followed closely, with 4,595, 966, and 722, respectively.

　　Among the orders received by Li Laijin and Gu Xiaofang, buying cigarettes and snacks on behalf of others is the most common. Li Laijin said that he once visited five convenience stores to help customers buy "Yoyo Mei". He also added WeChat with customers to determine the brand type through video communication.

　　What impressed Li Laijin the most was that he once copied more than 100 words of "sweet words" for a customer and sent it with the takeaway. As for the customer’s note request, Gu Xiaofang said, "The company does not have a clear rule that must be met, but we can help with everything we can, and it is easy to do."

　　There is no shortcut to more work and more "I want to be the webmaster of the takeaway station in the future"

　　When it comes to the difficulty of delivering food, it has to be said that traveling in bad weather, about which the riders "love and hate".

　　Delivered in bad weather at night, an order can earn about 13 yuan, which is 30% higher than the usual day. And when it comes to windy and rainy weather, takeaway orders also increase.

　　Li Laijin recalled that there was a drizzle that night on August 20, and he delivered 11 orders within two and a half hours, nearly double the number of orders from the previous day.

　　After the early morning, the order interval was relatively long, and the riders began to gather together to chat. Whether the new number of kilometers ran broke the record, and whoever rose to a new high on the rider’s single king list could make them chat in full swing.

　　Due to the long-term exposure to the sun, Li Laijin’s skin was dark, in sharp contrast to his original skin tone. "The wind and the sun are a little old, but I’m still young." Li Laijin quipped.

　　Li Laijin became a delivery rider two years ago. In his opinion, this industry is more work and more money. You can earn as much money as you run as many orders, and there are no other shortcuts. "You can get as much as you do in this industry." He likes this. "As long as I have orders, I can work harder and harder, and I am not afraid to stay up late." Li Laijin said he will continue to work in this industry. "I want to be a delivery station manager in the future."

　　As soon as Li Laijin finished speaking, a "ding ding ding" prompted him: "You have a new takeaway order, please deal with it in time". Then, he quickly got on the electric car and drove into the night. Text/This reporter, Zhu Jianyong, trainee reporter, Han Qian, intern, Zhang Yujie, Zhu Yadi

The saddest "subject three dances" from Haidilao;

How difficult is it to be an emotionally stable adult?

Recently, Haidilao’s "Subject Three Dances" became popular.

When many people go to Haidilao for dinner, they follow the trend and light up the "subject three dances" for the waiters. I thought it was quite interesting to watch dancing while eating.

But when I brushed the video of a girl with glasses dancing "subject three", I couldn’t help but feel uncomfortable. Compared with others’ silky "small tricks", her dance can be described as stiff and lifeless. Although the body is swinging with the rhythm and the movements of the hands are not falling, there is still no spirituality. So that you can feel her helplessness and reluctance across the screen. It was not until the music was finished that she breathed a sigh of relief and showed a relieved smile. Obviously not good at dancing, but still have to perform in front of customers, the little girl’s helplessness and embarrassment, we all know, have also experienced.

When we walk out of the campus, we will inevitably run around the world and bend our backs for five buckets of rice. Whatever emotions you have, you have to put them away and hide them.

Seeing a row of salesmen in the car, he was afraid of society and was not good at dealing with people. He has a prepared manuscript in his hand, but the words that have just arrived at his mouth are still very difficult to jump. The passenger next to him wanted to guide him, but he was even more embarrassed. Every time you shiver, you should wipe the sweat on your forehead. But even so, he still endured discomfort and continued to introduce products to passengers.

This is life and the world that every adult must face.

We often say: after 00, we will come to rectify the workplace. "If the leader scolds me, he will leave" and "If he feels uncomfortable, he will leave". But on the contrary, you can scold middle-aged people, especially those who have cars, houses and babies. Because at this age, they are burdened with thousands of weights, and life will not allow them to fall.

When a friend first started working, he worked in an advertising company. The project leader at that time was a middle-aged man in his forties. Once, because of the mistakes of team members, there was a typo in the corporate slogan designed for customers. After the customer received it, he came to the company to find fault. In front of dozens of people in the office, he was criticized and scolded, and the boss even scolded him like a dog.

"This is your boast of professional? Can’t you see such a short slogan and such an obvious typo? Does the company feed you for nothing every day? If you want to do it, do it. If you don’t want to do it, roll! " The middle-aged man bowed and bowed all the time, fearful and fearful, until the customer and boss were angry. And vowed that it would never happen again.

My friend thought at that time: What a shame! He must be leaving his job. But what I didn’t expect was that he was doing what he should do like nothing happened, as if the scene had never happened just now. Later, my friend learned from others that there was a paralyzed father in the man’s family, and now my mother-in-law has cancer. Everyone in the family needs money, no matter how hard the leader scolds, he has to suffer. If you knock out your teeth, you should swallow them in your stomach.

In the world of adults, it’s always a big job to make a living and a small job to save face.

I remember a line in "Please Answer 1988": "People really become strong, not because they guard their self-esteem, but when they put aside their self-esteem."

Lao Wang, who had to be a Buddhist since the media big V@, was the boss of a bankrupt private equity company and had to change careers and become a drip driver.

His former partners felt that he had no dignity, was too wronged, and sneered at him. He smiled and said nothing. Wonderful passengers, bossing him around and losing his temper, he also bowed and smiled and apologized.

He said that when people reach middle age, they can only be pragmatic, because at this age, there are old and young, and you can’t stop. If you can’t survive, you can only turn around and go on. Yes, no matter how hard and humble it is to make money, it can’t compete with the snow, rain and frost brought by reality.

Hide grievances, quit affectation and move on.

I saw a video the other day. In the hotel, the store manager prepared a program for customers to ride camels. As a result, a closer look revealed that the camel was actually played by a person. He has been bending over and hunching his back, with a man on his back. I am wearing a heavy camel suit, and I have holes in my face, but I don’t know where the air in my nostrils is going. Let the sweat cover your eyes and be dragged away by the person in front.

This camel is like you and me in reality. Our goal is the same: to shoulder the responsibility of the family and shoulder our own future. Live a good life.

Today, Manlu recommended the song "I really want to love this world" from Hua Chenyu in 2019. The sudden blank seconds in the middle of this song became a very deep memory point. Some people say that they have heard their own heartbeat, their own snorts, their own existence, and those who are falling apart. The song comment area is a large collection of tears. Listeners make wishes, bless and cheer up, and heal others and themselves.

Survived the narration.

Those gestures, those injuries

Read the original text

　　Recently, we saw a very special dance-"Subject III" dance, which became popular on the Internet and attracted wide attention. However, some people do not master the correct skills in imitation, resulting in physical injury or discomfort. So, what harm will this dance do to our health? How to prevent it? In this programme, we will talk about this topic.

　　Online big doctor: Wang Fasheng

　　Department of Orthopaedics, the First Affiliated Hospital of Fujian Medical University

　　Deputy chief physician, doctor of medicine

　　Topic of this issue: "Subject 3" is on fire, so don’t imitate it blindly.

　　What are the health risks of "subject three"

　　Injury of knee joint and ankle joint: In the process of dancing, the knee joint and ankle joint should be turned inside out quickly. If the strength and coordination are not enough, it may lead to the injury of lateral ligament of knee joint and lateral ligament of ankle joint, and may also affect cartilage and meniscus in joint.

　　Muscle strain: Dancing may involve some muscle groups that need great exercise. If you don’t warm up enough or your muscle strength is insufficient, it may lead to muscle strain.

　　Lumbar injury: You need to maintain a certain posture when dancing, especially when there are many waist movements. If the posture is incorrect or excessive force is exerted, it may lead to lumbar injury.

　　Increased cardiovascular burden: Dancing is an aerobic exercise. For some untrained people, excessive dancing may increase the cardiovascular burden.

　　When dancing the "subject three" dance

　　Pay attention to the following points

　　Warm-up: Proper warm-up before dancing can reduce the risk of muscle strain.

　　Moderate exercise: Don’t overexert or pursue complicated movements, but exercise moderately according to your physical condition.

　　Pay attention to posture: when dancing, you should keep the correct posture to avoid the injury of lumbar spine and knee joint caused by bad posture.

　　Seek medical attention in time if you feel unwell: If you feel obvious physical discomfort after dancing, such as pain and swelling, you should seek medical attention in time.

　　How to deal with injuries in dancing practice?

　　Stop practicing immediately: Stop dancing immediately after the injury to avoid aggravating the injury.

　　Ice compress: Apply ice packs or other cold compress materials to the injured area to help reduce pain and swelling.

　　Pressure bandage: bandage the injured part with elastic bandage to reduce swelling and bleeding.

　　Raise the injured part: raise the injured part to reduce swelling.

　　Seek professional medical advice: if the injury is serious or persists, you should seek medical advice in time and follow the doctor’s advice for treatment.

　　How to improve the flexibility and balance of the body

　　Flexibility training

　　Passive stretching: Passive stretching under the guidance of professionals, or self-passive stretching with the help of yoga balls and other tools can help improve the range of motion of joints and enhance the flexibility of muscles and ligaments.

　　Active stretching: through self-active stretching and some specific postures in yoga and other sports, the flexibility of muscles and ligaments can be enhanced, and the flexibility of joints can also be improved.

　　Warm-up exercise: Before starting formal dance training, proper warm-up exercise, such as brisk walking, running and skipping rope, can increase the body temperature, reduce muscle tension and improve joint flexibility.

　　Balance training

　　Swallow balance: On the basis of standing on one leg, leaning over and raising the left leg backward, while holding hands on the back of the right leg, keeping the head and ankle in a straight line can help improve the sense of balance.

　　Handstand: In dance training, practicing handstand and bowl-topping can help to improve the sense of balance.

　　Yoga: By practicing some balance movements in yoga, such as tree posture and Japanese sitting posture, you can improve your sense of balance.

On June 1st, BYD’s 2022 Tang EV was officially listed, and the price was 279,800 yuan-339,800 yuan after comprehensive subsidies. At the same time, four car rights and interests of "2 worry-free car purchase policies, 1 worry-free car protection, 5 exclusive VIP services and 5 online services of Zhilian" were launched simultaneously, which can be described as full of sincerity.

As the leader of pure electric SUV, the flagship strength of 2022 Tang EV has evolved in all dimensions, and with the three leading factors of "battery life, safety and technology" and the brand-new luxury quality such as six seats, it has set a new benchmark for the value of high-end pure electric SUV. Previously, the 2022 Tang EV also achieved an amazing record of only pre-selling 8505 units in 24 hours, and its strength rewritten the market structure of 300,000 pure electric SUVs.

The longest battery life is 730km, widening the user’s travel radius.

In terms of endurance performance, the 2022 Tang EV far exceeds users’ expectations, and the two-wheel drive version of CLTC can last up to 730km under comprehensive working conditions, showing the king’s posture that continues to lead. At the same time, the new car also offers 600KM exclusive type and 635KM four-wheel drive flagship type.

The 2022 Tang EV is equipped with a 108.8kWh large-capacity blade battery, which has the deepest power reserve of all BYD models, ensuring the industry benchmark endurance performance.

The joy of asking car owners to consciously be promoted to "Huawei car owners" has not passed, and Ren Zhengfei’s big mouth is ruthlessly drawn in their faces.

Today (March 31st), according to Cailian Comprehensive 36Kr, Huawei once again issued a decision announcement on the automobile business. The announcement was signed by Ren Zhengfei, founder and chairman of Huawei, and once again stressed that "Huawei does not build cars" and "valid for 5 years". In addition, Ren Zhengfei also put forward strict requirements for the exposure of Huawei logo in automobile design. "Emphasize that Huawei /HUAWEI cannot be used in vehicle promotion and appearance." The source said, and emphatically pointed out, "you can’t use’ Huawei asking the world’ and ‘HUAWEI AITO’. "

On the 8th of this month, AITO was still on its official Weibo."Openly" turned the familiar "AITO asking the world" into "HUAWEI asking the world".What is even more imaginative is that the Weibo was forwarded by the official account of "HUAWEI Terminal": "Where you want to go, Huawei asks about the car and always accompanies you!"

A small change in the name, in addition to causing the carnival of sales in the world that "Huawei cars can finally be called aboveboard", has once again aroused the N-degree conjecture of "Huawei makes cars":Is this time, Huawei really going to build a car by itself?

In fact, this name change is just a standardized adjustment of the marketing port between Huawei and Cyrus Auto, and it does not involve the adjustment of the cooperative relationship between the two parties.

Contrary to the outside world’s speculation that the relationship between the two parties is "broken", on February 25 this year, Huawei and Celestial Automobile also signed an agreement to deepen joint business in Shenzhen: Huawei terminals play a leading role in market and user demand insight and define new products; Sailis continues to do a good job in the iterative evolution of existing models, enhance the product experience, and launch a new platform for the future. The first flagship model under the new platform is scheduled to be released in 2023, which will be equipped with a high-level intelligent driving system, and a number of new models will be launched in succession.

At the signing ceremony, Yu Chengdong, managing director of Huawei, consumer BG CEO and smart car solution BU CEO, said:"Sailis is the earliest car company with the deepest investment and the most product models in Huawei".On other public occasions, Yu Chengdong has repeatedly stated that the cooperation between Huawei and Celeste will not decrease, but will increase instead of decrease.

The person who can have the first voice in Huawei is Ren Zhengfei’s father after all.

No matter how much Yu Dazui scampered, before a paper announcement signed and signed by the boss, he only sounded the golden bell and retired. Speaking of it, Yu Dazui’s psychology is better than that. Go back to headquarters to calm down a few words.Just watch Tesla reverse the car and hit the stone pier several times.

However, users who have only been "Huawei car owners" for 23 days may not be able to psychologically accept Huawei’s announcement with such a firm attitude and such a blunt tone. As soon as the gang put the "HUAWEI”logo purchased from a third party on the car’s ass, the" April Fool’s joke "was played on themselves, which was like" Wolf Warriors only has myself ".

Build a car and get stuck in Huawei’s neck

Is it difficult to build a car smoothly in China?

Ask the three electric brothers: Li Bin, Li Xiang and He Xiaopeng, and the answer is definitely "difficult, too difficult". However, everyone did not expect that this matter was not simple for HUAWEI, who had "Huawei before the day". According to incomplete statistics, in the past five years, Huawei has said nine times that it will not build cars through Ren Zhengfei, rotating chairman and internal documents.

For example, in January 2019, Ren Zhengfei publicly stated that Huawei will never build a car. In May of the same year, Ren Zhengfei also said that "Huawei will not switch tracks casually"; In 2020, Wang Jun, president of Huawei BU, said at the mobile phone new product launch conference that "Huawei does not build cars, but helps car companies build good cars"; In November, 2020, Ren Zhengfei said sternly: Whoever makes suggestions to build a car and interfere with the company in the future can be transferred from his post and look for another post; In May 2021, the official account of Huawei Group issued the "Statement on Huawei not making cars"; At the end of 2021, Yu Chengdong reiterated that "Huawei does not build cars" at Huawei’s winter flagship conference; At the 2021 financial report conference, Guo Ping, the rotating chairman, reiterated that Huawei does not build cars.

This time today, it happened to be the 10th time that Huawei said "no cars".

Is it difficult to build a 5G mobile phone? It is very difficult when the chip is stuck in the neck by Americans. However, Huawei has never said "no 5G mobile phones". Although we can use the 4G+ HarmonyOS system to provide a practical experience beyond 5G, we finally broke through many blockade lines and completed the landing of 5G mobile phones equipped with 5G chips.

But in the car-building track, Huawei gives people the impression that it is uncharacteristically evasive, often rushing to put the hat of "a first-class retired performance artist" on its head.

Why? Because you build your own car, there are too many links to be stuck: qualification, factory, production line, supply chain and so on. But if you don’t build a car, when you are a supplier, you can turn around and get stuck in the neck of the car company. Instead of paying money out of your own pocket and laying out design, production, channels, marketing and services from 0 to 1, it is better to empower cars and be a porter of money in the pockets of car companies.

After all, it is well known that people who make cars have money.

In fact, Huawei did this long before asking the world. From 2013 to 2015, Huawei launched the in-vehicle communication module ME909T, which was quickly installed on the production models of world-renowned automobile brands such as Audi and Mercedes-Benz. In 2014, Huawei’s car networking division developed the MirrorLink App based on Huawei’s mobile phone, and German Volkswagen immediately announced that the system would be used by domestic and imported people. In 2018, Huawei heavily modified a Porsche Panamera at the Mobile World Congress, enabling it to automatically identify the surrounding environment and make the most appropriate driving actions. For example, it was once boasted by the new forces of China, but it has not been thoroughly studied until today. "Emergency avoidance"; In 2019, Huawei released HiCar and HarmonyOS OS at the developer conference;

In 2020, Huawei released the smart car solution brand Hi: Huawei Inside; In 2021, Huawei Inside debuted on the Huawei HI version of Beiqi Extreme Fox Alpha S. In the same year, Aouita 11, another model in Huawei Inside mode, appeared. This year, the Celestial SF5 was not cold, and the new brand AITO Wenjie appeared with the latest HarmonyOS smart cockpit model M5, which is a production car that Huawei deeply participated in defining the whole process of design, production and manufacturing, and it is also the model with the highest "Chinese content" on the market so far.

The three paths for Huawei to build cars were also recognized by the public after the specific models landed:

1. Parts supply mode: traditional Tier 1 provides standardized parts, such as communication modules, motors, T-boxes, etc.

Second, the solution integration HI mode: traditional Tier 0.5, providing smart car full-stack solutions, MDC computing platform, intelligent cockpit, intelligent driving, intelligent Che Yun, etc.;

Third, intelligent car selection mode: traditional Tier 0, providing parts and solutions support, deeply participating in the whole process of product design, quality management, brand marketing and terminal sales.

Yu Chengdong is the leading intelligent car selection mode, while BAIC Polar Fox and Aouita are the HI modes at Wang Jun’s helm.

Different modes mean different "Chinese content". The level of "Chinese content" directly determines the brand’s position in the hearts of users and its sales performance in the market.

In the case that the complete delivery time is less than one year, the industry has made a cumulative sales of 78,000 units. Also in the first year, Weilai delivered 1.13 sets, Tucki delivered 16,600 sets, and the ideal delivered 32,600 sets, all of which didn’t ask much.

Behind the "explosion at birth", Yu Chengdong hosted a mysterious closed-door meeting. At the meeting, Yu Chengdong said: Huawei should not only help enterprises "build good cars", but also help them "sell good cars". "Not only help the horse, send a ride, but also participate in the whole process and deeply empower."

What do you mean by "full participation and deep empowerment"? Simply put, Huawei rolled up its sleeves and did everything, and Cyrus stepped back and became a mascot.

Appearance, cockpit, chassis, Sandian, car, audio, the core parts of these smart electric vehicles are all decided by Huawei. It’s not finished when the car is off the assembly line. Huawei directly drives the asking world to its own stores, let Huawei sell it in the first line, and endorse the asking world with Huawei’s brand power and sales channels.Where you can buy Huawei’s 4G mobile phone, you can buy the world.

BAIC Polar Fox and Aouita, which adopt HI mode, don’t have this treatment. In May, 2022, Beiqi Extreme Fox Alpha S HI version came by. Except for a "stunning" driver’s assistance test image, the reputation and sales of this car soon cooled down. A senior executive of BAIC Polar Fox also complained bitterly: After working with Huawei for so many years, people have gained a lot of voice. What have we got from BAIC?

BAIC got nothing, and Huawei got nothing. Wang Jun’s exit dealt a heavy blow to HI mode. At this stage, Huawei can maximize the empowerment of car companies and continue to make big money from the pockets of car companies, leaving only one smart car selection model.

Don’t let the car companies get away

On the road of smart car selection, Huawei has not gone smoothly this year. The most intuitive reaction is that the sales of the world have come down.

In January this year, the sales volume of the industry was 4,475 units, and in February, the sales volume fell to 3,505 units, which has been declining for two consecutive months. The pot in January can be thrown to the Spring Festival, but in February, the passenger car market rose both month-on-month and the "far ahead" sector fell against the market, which is somewhat unreasonable. What’s more, this is still the result handed over by the industry after the highest price reduction of 30,000 in January.

In the third week of March, the total sales volume of the industry was only 730 units. According to this estimate, the sales volume of the industry in March may have just climbed over 3,000 units, which was 500 units lower than that in February.It can be said that "last year’s sales were as fierce as a tiger, and this year’s look is in place."

After a short year of glory, the hometown of the literary circle has been almost stolen by all the effective forces that have been madly reducing prices. Go on, even the Volkswagen ID can’t be sold.

Everyone knows that Cyrus can’t carry it, and Huawei can’t be unaware of it, let alone put the "eggs" of making cars in the basket of the world. Jianghuai, Chery and Polar Fox have all joined the smart car selection model, which means that Celes is no longer Huawei’s "only child" in terms of product definition, core parts, supplier system, quality standards and sales service channels.

In the past, everyone said that they would buy a "Huawei car", but in fact they were going to buy a car. But after that, everyone said to buy a "Huawei car", and it is possible to buy Chery, Jianghuai, Extreme Fox or other brands.

You know, the more diluted the public awareness of "Huawei’s pro-son" in the world, the better the solution of smart car selection. It is Ren Zhengfei’s spring and autumn dream to live into Bosch in the era of smart cars, not Tesla.

By cooperating with more mainstream automobile brands, Huawei’s status as a top industrial chain supplier will be more recognized by the industry, and the bargaining power of large automobile companies and even international automobile companies will become stronger and stronger. This is the next big move that Huawei wants most.

Especially after falling out with Guangzhou Automobile Ai ‘an, Huawei is afraid that there will be another car company running away in the short term.

On the evening of March 27th, Guangzhou Automobile Group announced that the Ai ‘an AH8 project was changed from joint development with Huawei to independent development. Huawei will continue to participate in the development and cooperation of the company’s own brand models as an important supplier.The joint development mode between the two sides officially ended.

At the 19th China Automobile Marketing Summit in 2022, Xiao Yong, deputy general manager of Guangzhou Automobile Ai ‘an, publicly spoke out: "Huawei is a big-name supplier, and its price is relatively high and uncontrolled. We want to cooperate with Huawei, and we will find that there is basically no bargaining power."

Xiao Yong, Deputy General Manager of Guangzhou Automobile Ai ‘an

Huawei’s strength is evident in its ability to make large state-owned car companies accustomed to suppliers lose their bargaining power. However, such a powerful magic can only work in front of weak chicken car companies. After all, these car companies are counting on Cyrus’ story of Jedi rebound to reappear on themselves. Once faced with a BOSS-class car company with a large volume, a long history, a deep foundation and a tougher stance, Huawei may not dare to show its teeth too much.

These big car companies are not the first day to build and sell cars. In the past years, Huawei has not been "empowered" without you. Have I done it right?

Write it at the end

In the cooperation with Cyrus, Huawei has mastered the initiative in three aspects: first, all automobile data; Second, the calibration of vehicle core parameters; Third, the main sales channels.

To tell the truth, except for companies like Cyrus, few car companies are willing to give up their right to speak without reservation. Huawei is responsible for the calibration of car data and parameters, which is basically equivalent to handing over the soul and body of a car together, leaving only a few scattered skeletons to piece together.

Let Huawei sit in the living room for a while, show it to passers-by, and attract more people into the house. Car companies can’t be happier. But after sitting for a while, Huawei wants to be the owner of the house, and car companies will not agree as long as they are not stupid.

Car companies are willing to accept "the immortal of HarmonyOS car racing", but they will never accept "Huawei comes first, then there will be days".

Huawei hopes to stop the behavior of "asking for cars" to become "Huawei cars" and let car companies put their hearts back into their stomachs: we don’t build cars, we want to be good waiters for car companies.

As for whether car companies believe it or not, it’s hard to say. Anyway, SAIC Chen Hong certainly doesn’t believe it.

Can Huawei’s visual intelligence drive surpass Tesla? Pure vision confronts the dispute between cost and performance

Huawei HarmonyOS Ecological Spring Communication Conference was successfully held on the afternoon of April 11th. This conference focused on the new products of Zhijie S7 and MateBook. Zhijie S7, the first car built by Huawei and Chery based on HarmonyOS Zhixing model, was unveiled in November last year.

The intellectual community "returned to the furnace" after half a year, which attracted attention. Huawei chose to re-release it because of its Huawei visual intelligent driving system, which is the first time Huawei has launched a visual driving solution without lidar.

At the press conference, Yu Chengdong said that Huawei’s visual smart driver equipped with Zhijie S7 has surpassed Tesla, which is known as the "originator of vision", in real vehicle performance, showing strong confidence in its own scheme.

How does Huawei’s visual intelligence drive compete with Tesla’s visual intelligence drive on the premise of abandoning lidar? What kind of sensor does its technical strength come from? Huawei revealed the answer at the meeting.

Huawei officially released the first visual intelligent driving product-Huawei ADS Basic Edition. According to Yu Chengdong, the scheme can realize NCA intelligent driving navigation assistance on national expressways and urban expressways, including intelligent driving on and off ramps, coping with complex scenes such as road construction and cone-bucket diversion, and has certain ability to change lanes and avoid obstacles independently.

HUAWEI ADS basic edition is not equipped with laser radar, but realizes environmental perception through three millimeter-wave radars, 10 visual perception high-definition cameras and 12 ultrasonic radars, so as to build a visual intelligent driving scheme without laser radar.

At the press conference, Huawei ADS Basic Edition pointed directly at Tesla EAP(Enhanced Auto Pilot Enhanced Driver Assistance). Huawei claims that the comparative test results show that the coverage rate of Huawei’s visual intelligent driving is as high as 99.5%, the pass rate of ramp is 96%, and there is no degradation in the whole process. At the same time, it has the functions of intelligent speed regulation and identification of water horse cones. In contrast, the coverage rate of Tesla equipped with EAP is only 79%, the on-ramp pass rate is 68.75%, and it has been degraded 14 times, and it is impossible to identify obstacles of the opposite sex.

In terms of intelligent parking, Huawei’s visual intelligent driving has completely surpassed Tesla, which lacks support for different shapes, oblique rows and custom parking spaces.

As an optional function, Tesla EAP includes four functions: automatic lane change assistance, automatic navigation and driving assistance, intelligent calling and automatic parking, which need to be purchased at an extra cost. Tesla’s self-driving products are divided into three grades: BAP, EAP and FSD, of which BAP is the basic version and EAP is the enhanced assisted driving, and the two are free and charge $6,000 respectively. FSD is Tesla’s highest-level self-driving product, which has the functions of navigation-assisted driving, automatic lane change, automatic parking, intelligent calling, traffic signal recognition, and automatic turning of urban roads.

Zhijie S7 has launched five models, with the price range of 249,800 yuan to 349,800 yuan. Among the new models, the Ultra version uses a 100kWh battery pack, while the Max and Max+ versions have a price reduction of 20,000 yuan compared with the initial listing.

It is worth noting that Huawei Vision Smart Drive HUAWEI ADS Basic Edition is only installed in Zhijie S7 Pro rear drive long battery life version. In contrast, the version of Zhijie S7 Max with a price higher than 20,000 yuan is equipped with the same 192-line laser radar as that of Wenjie M9, with the longest detection distance of 250m, which is 20% higher than the industry average. Except for lidar, there is no difference in other configurations between the two models.

From this point of view, whether equipped with lidar has become the main difference between the basic version and the high-end version of Huawei’s ADS intelligent driving scheme, and the price difference between them is mainly reflected in this 192-line lidar.

What is the difference between Huawei Smart Drive with and without lidar? The former has enhanced its omni-directional anti-collision ability. After Zhijie S7 is equipped with laser radar, the effective range of forward active safety AEB is expanded to 4-150km/h, and the maximum braking speed is increased to 120 km/h; The effective range of lateral active safety is increased to 40-130km/h, and obstacles such as water horses can be actively identified.

The existence of lidar significantly improves the safety protection performance of vehicles, especially when dealing with emergencies such as "ghost probe". Previously, an owner of the M7 car in the border area encountered a "ghost probe" accident while driving at a speed of nearly 130km/h at high speed, and a pedestrian suddenly crossed the isolation belt and broke into the fast lane. Fortunately, Huawei’s intelligent driving system equipped with the M7 in Wenjie timely identified and took evasive measures to avoid the tragedy. This successful obstacle avoidance case is largely due to the lidar carried by the vehicle. Under extreme conditions, it is difficult to achieve such accurate perception only by visual sensors or human eyes.

In addition, the advanced version of HUAWEI ADS equipped with lidar has achieved wide coverage of roads in China, covering more than 40,000 towns and villages in China, including main roads, branch roads and even smaller roads. The third-party test data shows that the road coverage rate of the system has reached 99.56%. In contrast, the basic version of HUAWEI ADS-visual intelligent driving scheme is currently only applicable to NCA intelligent driving navigation assistance for national expressways and urban expressways.

Despite this, lidar is still recognized as the strongest sensor to achieve high-order assisted driving at this stage, even Huawei is no exception.

Why do some manufacturers choose to give up lidar? High cost is the main reason. Compared with the Zhijie S7Pro rear-drive long-life intelligent driving version, the Zhijie S7Max rear-drive long-life intelligent driving version is 20,000 yuan more expensive, mainly because of the addition of laser radar. Are consumers willing to pay for this?

In December, 2023, DJI Vehicle cooperated with Chery to launch the mass-produced model iCAR 03. This model adopts 7V pure vision sensor scheme, and the whole vehicle has no millimeter-wave radar or ultrasonic radar, making it the first automobile in China to realize high-order driving assistance function only by pure vision sensing hardware. With the help of pure visual sensor hardware, iCAR 03 also supports high-order assisted driving functions such as cross-layer memory parking, urban memory navigation and high-speed navigation.

The intelligent driving solution "Chengxing" launched by DJI Vehicle takes the inertial navigation stereo binocular sensor as the core sensing device, provides 7V and 9V pure vision sensor configurations, and supports extended multi-sensor such as lidar. This scheme can realize a variety of L2+ high-order intelligent driving functions with a computing power configuration as low as 32TOPS. Among them, the 7V sensor scheme includes an inertial navigation binocular vision sensor and five cameras, and the 9V sensor scheme adds two side-looking monocular cameras on this basis.

The hardware cost of DJI vehicle-mounted binocular vision intelligent driving scheme is extremely low. According to Shen Shaoshua, the person in charge of the vehicle in DJI, the hardware cost of the "Chengxing" platform can be reduced to less than 10,000 yuan, even reaching the level of 5,000 yuan, which is roughly equivalent to the price of a long-range lidar.

Both Chery’s cooperation with DJI Vehicle and Huawei’s cooperation have put forward a vision intelligent driving scheme without lidar version, which shows the active exploration and trade-off of domestic automobile manufacturers in the field of intelligent driving, and reveals how to introduce intelligent driving technology into a lower price range through trade-offs.

Although lidar is irreplaceable for its high-precision sensing ability, even Huawei acknowledges its watershed position between the basic version and the high-end version of HUAWEI ADS. However, with the intensification of competition in the automobile market, domestic automobile manufacturers are eager to introduce intelligent driving technology into a lower price range, and enterprises such as DJI and Huawei have achieved mass production of visual intelligent driving solutions that do not rely on lidar.

Therefore, reducing the cost of lidar has become a top priority.
