CCTV News:Satellite communication, because it has nothing to do with geographical environment and distance, is developing in the military and civilian fields all over the world. European and American countries started in the 1950s. When Sun Chenhua entered the 54th Research Institute of China Electronics Technology Corporation in 1986, China was still decades behind Europe and America in this project.

In the 32 years since he joined the work, Sun Chenhua has experienced the development process of China’s satellite communication from scratch and from weak to strong. She participated in it with a high sense of responsibility, presided over dozens of national and national defense key projects, and won 12 scientific and technological progress awards at or above the provincial and ministerial level (including 2 at the national level), ranking first in 7; In 2011, he was granted special government allowance by the State Council; In 2014, he was selected into the national 100 million talents project and was awarded the title of national young and middle-aged expert with outstanding contributions; He has won more than 10 honors at or above the municipal level, such as the National March 8th Red Flag Bearer, the Provincial May 1st Labor Medal, and the Provincial March 8th Red Flag Bearer. In 2017, he also won the Provincial Award for Outstanding Contribution to Scientific and Technological Innovation. She has trained the top domestic satellite communication team, and made outstanding contributions to the realization of China’s satellite communication from dependent introduction to independent research and development, accelerating the major transformation of China’s creation, promoting the deep integration of military and civilian satellite communication, and promoting the development of strategic emerging industries related to satellite communication between the country and Hebei Province. In 2018, she won the National May 1st Labor Medal.

Fight for 25 years to break the monopoly

When he came to the 54th Institute, Sun Chenhua first undertook the tasks of China’s first CDMA satellite communication system and the first tactical mobile satellite communication system. At that time, advanced technology was blocked by foreign monopoly. CDMA, which relies entirely on independent research and development, has experienced "eight years of anti-Japanese war", and the tactical mobile satellite communication system is even more difficult, with nearly 10 years of efforts before and after. When she was eight months pregnant, she stood up all night to solve the problems in the joint exam, returned to work three months after giving birth, and went on a business trip for more than 40 days when the child was less than one year old … … After more than ten years’ efforts, Sun Chenhua and her research group have broken through many key technologies and cultivated an independent research and development team of the "Professional Department".

She once said, "Many people don’t understand why I work so hard. Actually, it’s not that I don’t want to rest, it’s not that I don’t want to slow down, it’s because I can’t. Opening up a professional direction requires many people to make a lot of efforts, but losing a direction may be just an instant. "

Long-term experience accumulation has also laid the foundation for breaking foreign monopoly. In 2001, Sun Chenhua received a project from a military region and became the executive deputy chief engineer of the project to take charge of the overall work. This project involves a brand-new satellite communication system MF-TDMA. This is also Sun Chenhua’s first contact with TDMA. This technology has been monopolized by foreign countries for a long time, and users designated MF-TDMA system to be imported from foreign countries.

Sun Chenhua spent two months, consulted countless materials, thoroughly studied the relevant principles and data of this system, and completed the integrated application scheme. To be prudent, she asked the foreign company to give a plan. But she was keenly aware that the scheme they gave lacked a device, without which the system could not work normally. However, the foreign agent disagreed with her opinion.

"If you insist that there is no problem, then you have to sign a memorandum with us. If I am proved right later, you have to bear all the expenses of this equipment." Sun Chenhua said confidently.

Later experiments proved that Sun Chenhua was right. It was this "memorandum" that allowed foreign companies to give them 11 sets of equipment for free, each worth about 2,000 US dollars, with a total amount of nearly 200,000 yuan.

Six months after the introduction of equipment, foreign engineers came to the institute to communicate, which surprised him at the scene. "We have been developing this system for more than 20 years, and the system is particularly complicated. It is amazing that you used this system without training!"

In view of the accumulated experience in this project, in 2002, Sun Chenhua made repeated thoughts and made up his mind to develop our own TDMA communication system.

The road to project establishment is not smooth. The overall person in charge told her: "The country has long wanted to participate in this project, but it has been afraid to participate. ‘ Generation star ’ At the time of research and development, someone mentioned this system, but eventually gave up due to technical difficulties. " However, Sun Chenhua was overcome with difficulties. "Although it is difficult, this new system must be mastered in order to develop satellite communication." She organized a team to repeatedly study and demonstrate and repeatedly do technical simulation. Then, a man carrying a big laptop went to Beijing to report and ask for instructions. After three years of hard work, the project was finally successful.

"This project has been particularly hard." Sun Chenhua said that the technical difficulty is high and the development progress has been delayed for nearly one year. But in order to hand over the most perfect equipment, she resisted the pressure and tried again and again, striving for perfection. In 2011, this dual-mode satellite communication system, which she and her team have worked hard for nearly 10 years, won the second prize of the National Science and Technology Progress Award with outstanding innovations of more than a dozen invention patents and sales revenue of nearly 500 million yuan.

A "spiritual leader" who plans development with an eye to the future.

Over the years, the projects developed by Sun Chenhua have achieved fruitful results. 15. Eleventh Five-Year Plan, Twelfth Five-Year Plan and Thirteenth Five-Year Plan … … Sun Chenhua has been researching and developing in the field of satellite communication, and has built the first three-tier and three-sided operation management control system of satellite communication in China. Her multi-beam and large-span rate range networking solution has broken through dozens of key technologies and developed more than 100 kinds of high-tech products, which has reached the domestic leading and international advanced level in general.

Spatial information resources are important strategic resources of the country. The integrated information network between heaven and earth is a major infrastructure of the country. Standing at the height of national needs, China Electric Power Branch concentrated superior resources and set up the project team of "Integration of Heaven and Earth", in which Sun Chenhua is one of the deputy chief designers.

"The needs of the unit are the greatest affirmation for me." After receiving this task, Sun Chenhua went into battle with his team: sorting out and breaking through key technologies, sorting out basic conditions at home and abroad, and formulating the overall scheme of "space-based access network" and "ground-based node network" … … With a solid technical foundation and many years of engineering experience, Sun Chenhua played an important role in the major project of "integration of heaven and earth", became the "spiritual leader" in this field, and personally built the national meridians.

In order to bring the project to xiong’an new area and promote the subsequent commercial aerospace development in Hebei Province, she innovatively put forward internationally leading low-orbit access network schemes such as combination of width and narrowness, functional integration, inter-satellite interconnection and global seamless service, and presided over the development of the test system. Presided over the completion of the ground application network scheme covering 15 points across the country. It is estimated that after 2020, the industrial chain driven by the integrated information network of heaven and earth will produce an output value of more than 3 billion yuan every year.

"Her hard work is beyond your imagination."

Since August 2016, Sun Chenhua has led the professional department to apply for more than 30 pre-research projects, of which nearly 20 pre-research projects have been won. Every project report needs to be PPT, and she should read every PPT carefully. When she has time, she will do it herself, and it will be midnight, and it is common to work until one or two o’clock in the morning. Especially before the defense, Sun Chenhua will accompany everyone to revise all kinds of documents and strive for perfection, never letting go of every detail.

She is in charge of many things and often travels. Pre-research project application, bidding and so on, many things should be concentrated on the weekend to deal with. Han Ning, director of the general office of the professional department of Weitong, said that she had to be consulted for a lot of work. On weekends, everyone lined up one after another like a lantern, making her often busier than usual, working almost until eleven or twelve o’clock every night. Everyone sees her hard work, and it hurts in her heart.

She sometimes asks herself: whether you work hard or not, the result will be much worse. How to choose? Do you want to choose to bloom in a limited number of years, or do you want to be mediocre and happy? Because she often looks to the future, she is still afraid to relax today when she is over half a year old. "Scientific research is grinded out. In addition to a professional foundation, engaging in scientific research must have the determination to persist in scientific research for a lifetime." In the past 32 years, she has promoted the major transformation of satellite communication from dependence on introduction to creation in China, and will devote her whole life to achieving "China leading" in satellite communication.

In the knockout stage of new energy vehicle enterprises, Xiaomi’s "high-profile" entry into new energy vehicles has brought a lot of shock to the automobile industry. Since the technical conference, the hot topic of Xiaomi Auto has been constant, and the market is expected to be full, but it is also trapped in various disputes. At present, the official press conference will usher in a countdown, and facing the real market test, Xiaomi Automobile will usher in a new round of public opinion risk impact.

Author Miao Jian Research Institute

According to the data of Miaojian Information Big Data Monitoring Platform, from December 25th, 2023 to March 24th, 2024, 1,699,200 items related to "Xiaomi Auto" and "Xiaomi SU7" have spread across the whole network, and related topics have been listed on the hot search lists of 12 platforms including Tik Tok, Weibo and Baidu, with a total of more than 230 times, and the cumulative time on the list has exceeded 1,400 hours.

Miao Jian information analysis found that

In the "price war" period, coupled with the brand impression of "high cost performance", XIAOMI SU7, the first+first Xiaomi car, has a high degree of attention, and the public opinion has crushed all other single-brand models for three months.

The topic of price runs through the warm-up period of products. Compared with design and technical topics, price is still the most concerned topic of public opinion before the products in the automobile industry go on the market.

In 3 months, there were 319 articles related to SU7, with an average of 3.5 articles published every day. Lei Jun continued to speak out through official micro by virtue of his personal influence, which played an important leading role in the overall topic communication. Timely dispel rumors, disclose important information and respond to public concerns, constantly create and form hot topics, and maintain product popularity.

On March 28th, Xiaomi SU7 will be officially released at the listing conference, and the risk window of Xiaomi Auto’s public opinion will be reopened soon. After the product is officially listed, the risk of public opinion around the final pricing combined with test drive, comparative evaluation, marketing, sales delivery, new car problems, accidents and so on will continue to rise.

01

Sorting out the main communication threads of Xiaomi SU7 before listing.

On November 15th, 2023, the Ministry of Industry and Information Technology issued the Announcement of Road Motor Vehicle Manufacturers and Products (the 377th batch) and the Catalogue of Energy-saving and New Energy-using Vehicles with Vehicle and Vessel Tax Relief (the 56th batch), in which Xiaomi Automobile is located.

The recent major communication/public opinion events of "Xiaomi Automobile" are as follows:

A On December 25th, 2023, the official blog of Xiaomi Automobile announced that the "Xiaomi Automobile Technology Conference" would be held on December 28th, and Xiaomi officially revealed the relevant information of Xiaomi Automobile for the first time.

B On December 27th, 2023, Lei Jun released a message in his personal Weibo, paying tribute to the pioneers of new energy vehicles in China, such as BYD and Weilai. That night, Xiaomi Automobile paid a grand tribute to Huawei, Tucki, Ideality, BYD and Weilai through outdoor billboards.

C On December 28th, 2023, Xiaomi Automobile held a technical conference. Lei Jun said at the Xiaomi Automobile Technology Conference: "So don’t shout 99,000, it’s impossible." "Anyone who has this kind of performance and configuration will get more than 400,000 yuan, so there is no need to talk about 149,000 yuan, or we should respect technology."

D On January 2, 2024, a spokesman for @ Xiaomi Company wrote a rumor: We recently paid attention to a picture about Xiaomi’s automobile industry chain. After verification, at least 50% of the contents were completely wrong. It said that the information summary of the "industrial chain" pictures is full of loopholes and misleading to the public and investors, which is deeply puzzled.

On the same day, some netizens discussed the price of SU7 under Lei Jun Weibo. Lei Jun said: "Is there an opponent within 500,000?" . This reply triggered speculation that the final price of SU7 may be between 200,000 and 500,000 yuan.

E On January 5th, 2024, the car blogger "Li Sir Jiaolu" released Weibo news, questioning the suspected illegal behavior of Xiaomi Auto parking service video, and its comments questioned the blogger’s double standard.

F On January 8 -10, 2024, Xiaomi Automobile released "Answering 100 Questions from Netizens" in batches.

G On January 20, 2024, Lei Jun said in an interview with CCTV: "It is expected to be officially listed in the first half of 2024, and now it is undergoing small-scale mass production. This car has a very strong configuration and a very high cost. I think everyone is joking when they shout 99,000 yuan, 149,000 yuan or even 199,000 yuan. Pricing may indeed be a bit expensive, and we will announce it at the official product launch conference of Xiaomi Automobile. "

H On January 23rd, 2024, a spokesman for @ Xiaomi Company issued a document in Weibo to refute the rumor that Xiaomi Automobile was delivered in June. Recently, there have been a lot of rumors about the delivery time of Xiaomi Automobile. The relevant information is pure fabrication, completely false. Once again, the official release and delivery time of Xiaomi Automobile are subject to official information.

I On January 30th, 2024, Wang Hua, general manager of Xiaomi’s public relations department, responded to the issue of # Xiaomi’s policy price exposure # in Weibo, saying that in recent days, everyone should have seen the internal vehicles start to be licensed, which is also to test all the processes of running through the sales and delivery, and of course, buying insurance is also one of the links.

J On February 3, 2024, Lei Jun announced in Weibo that Xiaomi SU7 was conducting a comprehensive road test nationwide to make final preparations for the listing of Xiaomi SU7, and would focus more on the automobile business.

K On February 23, 2024, it was reported that Xiaomi’s early employees close to Lei Jun revealed that "Lei Jun is making a big move. The first car owners who buy Xiaomi cars may give them licenses if they don’t have a Beijing license." In response, a spokesperson for @ Xiaomi Company responded that it was completely inaccurate. Xiaomi’s pricing, delivery and sales policies are subject to the official release, which is well known.

On February 28th, 2024, Lei Jun voiced "Apple canceled making cars" and said that "Apple users will definitely be the best choice when purchasing smart electric cars".

M On March 12, 2024, Lei Jun released the official announcement of Xiaomi Automobile in Weibo on March 28.

N On March 13th, 2024, the reporter of science and technology innovation board Daily learned from the sales channel of Xiaomi Automobile that the price of SU7 top distribution will exceed that of M5 top distribution (about 300,000 yuan).

O On March 19th, 2024, a spokesperson of @ Xiaomi Company issued a rumor, saying that the Xiaomi road test vehicle was closed-loop tested on the closed-loop expressway, and there were no violations such as high-speed illegal U-turn, speeding, and escaping high-speed tolls.

P On March 20th, 2024, Wang Hua, general manager of Xiaomi Public Relations Department, denied that "Xiaomi Automobile will issue 1000 Xiaomi SU7F codes". "As far as I know, there is no channel for priority purchase of F codes".

02

Public opinion concerns

According to the monitoring results of Miaojian Information Big Data Platform, price is the most concerned topic of public opinion. Among them, the discussion of Xiaomi automobile product itself mainly focuses on price, technology and design.

I. Price

In the technical conference and CCTV interview, Lei Jun repeatedly said "Don’t shout 99,000, it’s impossible", "Anyone with this performance and configuration will have to pay more than 400,000, so there is no need to talk about 149,000", "The price is really a bit expensive, and 199,000 is impossible", and he even replied in Weibo "Is there an opponent within 500,000?"

The "cost-effective" label of Xiaomi’s mobile phone is deeply rooted in people’s hearts, which makes Xiaomi’s car trapped by the public opinion of "low price" and "low end" before its release. From the media point of view, Xiaomi held this technical conference just to break the existing public opinion situation, and wanted to tell everyone that "we still have to respect science and technology".

On January 5th, Wang Hua, general manager of Xiaomi’s public relations department, released the ultimate rumor about Xiaomi Automobile in Weibo: until the end of the official Xiaomi Automobile product launch conference, all the information and posters with the version and price of Xiaomi Automobile were false. On January 8th and 9th, Lei Jun Weibo released Xiaomi Auto to answer 100 questions from netizens, and also officially answered questions about pricing.

On February 21st, the price of # Xiaomi Auto was searched again in Weibo, and some cars said from the media that "the current situation is even more complicated". On March 6th, Li Guoqing, the founder of Dangdang, sent a video calling Lei Jun, asking Lei Jun to price Xiaomi for 150,000 to 200,000 yuan. On March 13th, the media learned that the price of SU7 top plate will exceed that of M5 top plate (about 300,000 yuan).

The release of technology, the voice of executives, the pressure from inside and outside the industry, and the wind of prices continue. The car industry is in a big environment of "low price". Faced with the expectation of many "rice noodles", Xiaomi will insist on going upstream and entering the mid-to high-end market in pricing, or push up the consumer’s budget through marketing and kill at a low price. The continuous price topic and various speculations will make Xiaomi SU7 in the preheating stage occupy the public opinion field in the car industry.

Mainstream media: The participating media are mainly financial media such as Caijing. com, national business daily and China Business News, mainly to report the latest development of Xiaomi Automobile and the contents of senior executives’ speeches, with few media comments.

Professionals: Guess why Xiaomi Auto has not announced its pricing.

According to national business daily, Pang Rui, a well-known brand expert and founding partner of Zhansheng Communication, "So far, regarding the pricing of Xiaomi SU7, Xiaomi is mostly denying the price circulated on the Internet, without giving any positive hints. Perhaps this is also a pricing test strategy, that is, by observing the market’s public opinion feedback on different rumored prices, Xiaomi can constantly correct the price and gradually form the final pricing in the process. "

According to China Net Finance, Liang Zhenpeng, a senior industrial economic observer, believes that "on the one hand, it takes a long time for a car to go from PPT to commercial mass production, and then to improve the yield to meet the standards of product quality, process performance and other technical parameters. For Xiaomi, the cost is difficult to determine for the time being, so the price has not been disclosed yet; On the other hand, in the process of R&D and manufacturing, Xiaomi’s automobile products will continue to be iteratively updated, and the cost will continue to change, thus affecting the final pricing. "

From the media: initiate pricing speculation discussion and analyze the situation of Xiaomi SU7 according to the actions of other car companies.

Weibo-Bigu: I feel that BYD’s price reduction can kill everything. Not all of Gaohe has fallen, and Wei Xiaoli has a hard time. If BYD starts to enlarge its recruitment further, Xiaomi will be miserable.

Weibo-_-Second Senior Brother: BYD took the lead in killing the red eye within 100,000 yuan, and extremely krypton Tucki pulled the 800V to within 200,000 yuan. Therefore, the 400V single motor introduced by Xiaomi SU7 does not have the version of lidar. Once it exceeds 200,000, it will be difficult to be a new brand. Xiaomi has only one chance to play cards.

Netizen: ridicule pricing, discuss the price in mind, think about marketing routines, and discuss price reduction issues.

First, throw a confusing 300,000 yuan to the outside world, and blow the wind. When the listing is low, it will be set at more than 20, and then the whole network will say that it is cheap and buy buy will buy it.

The marketing gimmick is full, just don’t know if the final price will satisfy the public.

Almost. Aren’t you tired of this old routine?　

Rumor? I think this is what Lei Jun wants. All the way from Xiaomi mobile phone is a similar eye-catching strategy.

The price was not announced at the press conference. By understanding how much users are willing to pay for Xiaomi Automobile, pricing is made according to this price.

If it’s so expensive, you can only wait for Redmi car; As expected, it may be accepted that there are so many piles of materials at the technical conference.

Didn’t a lot of news say 500 thousand before, and now another 360 thousand, I think it’s better to wait for the press conference

BYD’s 200,000 cars haven’t been reduced in price, so we can sell them at whatever crowd we target. If BYD drops another 10,000, we will buy them from people within 100,000.

It has been delayed for too long, and there is no enthusiasm for attention.

Second, technology

Under the public opinion environment that new energy car companies generally bear the original crime of technology, the louder the slogan of "self-research" is shouted, the more attention and condemnation it attracts. Lei Jun publicized "self-research" for many times at the press conference. Later, due to the constant controversy over "self-research", the rumors mainly focused on Xiaomi V8s super motor and Xiaomi Titan alloy, and thought that Xiaomi Automobile was just an assembly plant.

These false information have been rumored one after another. On the night of the press conference, there was a voice that Xiaomi V8s super motor was from Huichuan technology, not self-developed. Huichuan technology immediately responded to "V8s motor is self-developed by Xiaomi" on the stock trading platform, but some netizens still said, "Is Xiaomi fully self-developed? How did Huichuan know?"

In addition, the Titan alloy developed by Xiaomi was thought to be plagiarized by a university teacher, and then the teacher responded that "the ingredients were wrong, and Xiaomi did develop it himself".

A picture of Xiaomi automobile industry chain was also exposed on the Internet, which shows that most parts of Xiaomi automobile are supplied by third parties. In this regard, Xiaomi Automobile denies that at least 50% of the contents are completely wrong.

Since the media: Based on the information released by the government, this paper analyzes the five major technologies of Xiaomi Automobile and whether it is "self-developed". The overall tonality of the public opinion field is neutral.

Wechat-Zinc Scale: An industry insider told Zinc Scale, "This is the same as satirizing that the large aircraft C919 is’ assembled goods’, either ignorant or with ulterior motives. The key lies in how many core technologies are mastered, not how many parts are mastered. For example, the large die-casting equipment comes from a third-party supplier, but the large die-casting equipment cluster system is self-developed by Xiaomi Automobile, and integration is also a creative ability."

Wechat-driving AUTO: In fact, how much self-developed things Xiaomi has at this conference is something that can neither be confirmed nor falsified. Because the conclusion of netizens may be just a misunderstanding. The crux of the problem lies in who owns the intellectual property rights of technology. If it is a joint development but the intellectual property belongs to Xiaomi, from the perspective of property rights and law, Xiaomi claims that there is nothing wrong with "self-research", and even from the perspective of public order and good customs in the automobile circle, it is not against it. However, if the external publicity is renamed as "joint development", the shocking effect of publicity will obviously not be achieved, and the personnel of technological subversion will not be established, so "self-research" is necessary.

Wechat-poison tongue technology: self-research in the eyes of netizens and self-research defined by the industry are often not the same thing. Xiaomi’s plan is to explore a rotor material with leading strength with partners, thus developing a brand-new motor with 27,200 rpm. Xiaomi, a die casting machine, is not self-developed. What is really self-developed is the "millet large die casting integrated cluster". In other words, Xiaomi has developed a set of most suitable and efficient production lines, and the die casting machine is also customized by partners according to the needs of this production line. This actually does not prevent Xiaomi from saying that it is self-research.

Netizen: Mainly for poking fun at/not believing in Xiaomi’s self-developed technology, and thinking that Xiaomi encountered the black water army.

Obviously, the motor you bought has to be said to be self-developed, and you are really cheeky.

Just look at the technology of millet blowing, don’t take it seriously, let’s talk about it after seeing the actual effect.

The maximum speed limit is 120. Do you think the motor is fast and useful? Don’t argue about concepts!

Boy, the technology after these years has been pre-developed successfully now.

The precipitation of other big factories for decades and hundreds of years can’t compare with Xiaomi’s research and development in one year?

A certain group stayed up late to prepare for the exam in order to do a background check for Xiaomi Automobile.

Black Xiaomi and those who blow Huawei are the same type of accounts.

Let’s just say that a tree catches the wind. What do you think is the scandal of the dying joint venture?

Now the atmosphere is very funny, saying that Huichuan can’t prove that Xiaomi is self-researched, so Xiaomi is not self-researched. So who said it? Xiaomi said it himself. Do you believe it after Xiaomi said it himself?

Huichuan is quite powerful, with the existence of the top few in China.

Third, the design

1. Appearance is similar to Porsche controversy

Since the appearance of Xiaomi automobile in the catalogue of the Ministry of Industry and Information Technology on November 15, 2023, the appearance of Xiaomi SU7 has been controversial. Because the front face and side of the car are very similar to Porsche, it is ridiculed by netizens that "Mi Shijie" is "not that Porsche can’t afford it, but that Xiaomi is more cost-effective". One plus designer Haoran said that he copied Porsche Paramera, and many self-media published the comparison chart of Xiaomi SU7 and Porsche Taycan. Some cars discovered from the media that Lei Jun Weibo once revealed that he was reading Porsche-related books; Another online picture shows that Xiaomi’s product Xiaoai’s recognition result of Xiaomi SU7 is Porsche. The superposition of all kinds of "coincidences", coupled with Lei Jun’s mention of "comparable to Porsche Tesla" and "the goal is to compete with Porsche" at the press conference, Xiaomi Automobile is caught in a "plagiarism storm".

In addition to these doubts and ridicule, there are also many professionals who speak for Xiaomi. Regarding the question of whether Xiaomi automobile plagiarized or borrowed, many disputes helped the outbreak of public opinion.

There is no plagiarism:

Domestic automobile styling design has long bid farewell to the stage of plagiarism. As for what it looks like and what nickname it is, it is the category of the media. Sometimes quite speechless, there is always an angle to black millet; In industrial design, the streamline of coupe should be beautiful and low wind resistance, and it can only look similar, which is the only choice determined by aesthetic and scientific path after industrial design develops to a mature stage.

Ridicule plagiarism:

You don’t understand, this is actually a tribute to Porsche, the predecessor of the industry; Low-key, I think it can rival the aircraft carrier; Because it is comparable, the exterior is copied from Porsche and the interior is copied from Tesla. Combined, it is perfect.

Mention that other car companies are also suspected of plagiarism, implying that sunspots "follow the trend" and "double standard":

I’m curious why many netizens plagiarized Xiaomi’s car because it looks similar to Porsche, but no one said that the car chosen by Huawei is similar to Porsche.

2. Controversy over the design of semi-hidden door handles.

In addition, the conference also announced the patented design of the semi-hidden handle. Its embedded design not only optimizes the aerodynamic efficiency of the vehicle, but also retains the aesthetic feeling of its streamlined appearance. What’s more outstanding is that it skillfully solves the freezing problem in cold weather and avoids the pop-up difficulty that traditional pop-up door handles may encounter. However, some netizens complained that this design was "very familiar", and then Lei Jun also emphasized in Weibo that the semi-hidden door handle was completely different from the early pure mechanical structure "upturned semi-hidden door handle".

3. Other design disputes

In addition, the plum blossom wheel hub, the borderless cobblestone rearview mirror and the 105L front reserve box have also been ridiculed by some netizens that "this design has existed for a long time".

03

Analysis of communication characteristics

1. Price-related topics account for a large proportion, which is the key node to arouse public opinion.

Before the technical conference, Lei Jun revealed in Weibo that "Xiaomi SU7 is a bit expensive", and the topic was on the hot search, and public opinion tended to rise. Then there is the recurring price topic: # Rice flour expects Xiaomi car to be around 300,000 # # Lei Jun said that Xiaomi SU7 has no rivals within 500,000 # # Xiaomi car policy price exposure # # Xiaomi car pricing strategy exposure # and so on.

According to the data of Miaojian Information Big Data Monitoring Platform, the high point in the communication trend of Xiaomi Automobile’s price issue almost corresponds to the high point of Xiaomi Automobile’s overall communication trend. The price issue is the main aspect that causes public opinion controversy and is the key for Xiaomi Automobile to maintain a high degree of public concern.

2. Executives and officials frequently voice and refute rumors to promote the spread of topics.

In the early stage of the new car sale, the public opinion field was flooded with false information about price and technology. Lei Jun and Wang Hua, general manager of Xiaomi Group’s public relations department, repeatedly answered questions and rumors in Weibo. The Weibo account "Xiaomi Company Spokesperson" also released rumors about pricing and sales policies, delivery time and technology industry chain. On January 8 -10, Xiaomi Automobile released "Answering 100 Questions from netizens" to comprehensively answer all questions and focus on public concern, which to some extent avoided the persistence of false information on the brand.

According to the display of Miaojian Information Big Data Monitoring Platform, every time executives or officials intervene in the topic, it will cause a certain degree of public opinion fluctuation. On the whole, Xiaomi Automobile still holds a dominant position in the right to speak in public opinion. Although it is riddled with rumors, it has caused some self-media smearing and ridicule by netizens. However, the rapid rumor-dispelling and pre-emptive public relations method not only dispels the doubts of the industry, but also provides a continuous discussion for its own products.

3. The ups and downs of brand reputation are not obvious.

Miaojian Information Big Data Monitoring Platform shows that Xiaomi Automobile has a relatively large amount of sensitive information on the day of the technology conference, the rumor of giving Beijing license, and the extremely high-level executives talking about Xiaomi Automobile at the press conference. In the three months from the technical conference to the official conference, the topic headed by price is still in the discussion stage, and the related negatives are mainly rumors, which have limited practical impact on the brand reputation of Xiaomi Automobile.

04

Public opinion risk judgment

1. Be involved in the "price war" dilemma after pricing is released.

In the year of the Year of the Loong, Tesla took the lead in price reduction, and then BYD made a low price of 79,800 yuan. Changan Automobile, Nezha Automobile and other brands followed suit, and this year’s price war began. On February 27th, the new Extreme Krypton 001 went on the market, with a starting price of 269,000 yuan. Some media claimed that "Extreme Krypton gave Xiaomi a problem". On the day when Xiaomi Automobile announced its pricing, it will inevitably bring certain "fluctuations" to the auto market. For Xiaomi Automobile, whether to follow up the price war may become a hot topic in the market. How to break through in the price knockout is the challenge that Xiaomi is about to face.

2. Repeated marketing, led by price, leads to self-attack.

The topic of manufacturing is Xiaomi’s marketing style in the field of mobile phones. When it is used in Xiaomi cars, it is the product positioning that is close to Porsche, Tesla and other high-end products after frequent price snooping and opening. The price topic was frequently searched, and the executives responded many times. Before the conference, they paid tribute to other car companies and said that they were "comparable to Porsche" …………………………………………………………………………………………………………………….

3. It is difficult to get rid of labels such as "imitation" and "cottage"

Whether it is the marketing method of the brand or the malicious smear of peers, it has been labeled as "imitating foreign models" since it came out, which can easily deepen the stereotype of the public and thus produce psychological resistance to the brand. In the car sale stage, similar teasing will continue, which will affect short-term sales to some extent. In the long run, whether Xiaomi SU7 can get rid of the negative label with a good enough driving experience, make excellent performance a competitive advantage of the product, and reverse the relatively negative market perception will also be the focus of public opinion.

4. Other negative brands, negative road test and negative test drive affect Xiaomi’s reputation.

Recently, a Xiaomi employee said on the Internet that Xiaomi will lay off employees on February 29, and "only notice, no consultation" and "no year-end bonus after being laid off", and finally said "think twice about buying a Xiaomi car". On February 3rd, a photo of a suspected collision of Xiaomi SU7 during the road test came out on the Internet, which aroused public concern. Shake consumers’ decision to buy a car. On March 19th, Xiaomi Auto officially responded that the content was maliciously misinterpreted by some accounts, and there was no violation, and it was still communicating with the expressway group on false information. Xiaomi Automobile has attracted much attention. Once the public opinion such as the negative operation of Xiaomi Group, the negative road test of Xiaomi Automobile and the negative test drive experience of new cars in offline outlets occur, it will lead to a decline in its reputation, which will easily affect the marketing process and sales of Xiaomi Automobile.

5. Brand executives’ speeches caused controversy.

Lin Bin, vice president of Netcom Xiaomi, said in a circle of friends, "Driving Xiaomi SU7 from Beijing to Shenzhen office, starting at 7: 30 on Saturday morning and arriving at Shenzhen office at 11: 00 on Monday morning, the whole journey is 2320 kilometers, passing through Wuhan and Guangzhou, and charging for 5 times. (This is a great experience.) This content triggered some speculation about the endurance of Xiaomi SU7 from the media, and concluded that the endurance achievement rate was low. Among them, the self-media account "Chatting Car" only converted electricity consumption by charging times, and the published article was not rigorous, which was complained by Xiaomi Automobile. Some also said from the media that "if it is not full every time, he will definitely explain it clearly in the text. What an important habit it is." Executives’ speeches are often easily amplified and interpreted by the media, and if there is any imprecision, it will easily lead to controversy.

6. Peer-to-peer friends’ speeches caused controversy

Regarding Xiaomi Auto’s tribute to its peers, Yang Xueliang, vice president of Geely, said that "it’s too late". "If people always want to be paid tribute, it’s over, but if people always want to pay tribute to others, there is no promise"; Zhu Ling, vice president of Krypton, also posted a blog suggesting that Xiaomi’s marketing is more and more like health care industry’s, and commented sharply that "the last one who shouted out eco-cars seems to be LeTV mobile phones". On February 27th, at the launch conference of the brand-new Extreme Krypton 001, Extreme Krypton executives talked about Xiaomi Automobile’s "marketing is worth learning", and then # Extreme Krypton executives # boarded the hot search. After the listing of Xiaomi Automobile, the subsequent announcement may also lead to such cynicism and public controversy.

National business daily News: Recently, the abnormal event of nucleic acid test results in Lanzhou, Gansu Province has aroused widespread concern. Subsequently, many online articles pointed the finger at Zhang He, the founder of Shenzhen Nuclear Gene Technology Co., Ltd. (hereinafter referred to as Shenzhen Nuclear Gene), the parent company of the involved company, and Zhang Shan, who served as the supervisor of several subsidiaries of Shenzhen Nuclear Gene.

In fact, the abnormal event of Lanzhou nucleic acid test results is not the first time that Shenzhen nuclear gene has problems. In January, 2021, Xingtai City, Hebei Province held a press conference on the prevention and control of COVID-19 epidemic, and reported the false report of nucleic acid test results in Longyao County. The company involved was also indirectly 100% controlled by Shenzhen Nuclear Gene.

What is the situation of Shenzhen nuclear gene in the whirlpool of public opinion? On the afternoon of November 28th, national business daily reporter visited the headquarters office of Shenzhen Nuclear Gene in Nanshan Zhiyuan, Nanshan District, Shenzhen. The field staff refused the reporter’s interview on the grounds that the leader was absent. A property manager of the building told the reporter that the person in charge of the company basically came to the office every morning before leaving the company this morning.

Shenzhen Nuclear Gene was established in 2012. According to official website, the company has set up 64 subsidiaries and 50 laboratories nationwide. According to the incomplete statistics of the reporter of national business daily, the company has newly opened more than ten medical laboratory co., Ltd. in various parts of China this year, and these medical laboratory may mainly provide COVID-19 nucleic acid detection services for various places. The reporter noted that the company’s expansion process is inseparable from the form of joining in investment promotion.

Lanzhou Nuclear Huaxi Laboratory was notified.

Recently, an abnormal event occurred in Lanzhou, Gansu Province. On November 25, Lanzhou Health and Health Commission issued a notice saying that on the morning of November 24, 2022, when Qilihe District of Lanzhou organized the transfer of positive infected people according to the results of nucleic acid testing, it was found that the health codes of individual people to be transferred showed negative nucleic acid testing. In view of this situation, the Qilihe District Joint Defense Office immediately reported to the Municipal Joint Defense Office. The Municipal Joint Defense and Joint Control Leading Group attached great importance to it, invited quality control experts from the Provincial Clinical Laboratory Center to participate, and organized a joint investigation team from the urban health and public security departments to check the relevant situation.

According to the above notice, after on-the-spot verification, the basic situation of this incident is: Lanzhou Nuclear Huaxi Laboratory received the nucleic acid test samples, and according to the laboratory testing process, at 18: 00 on November 23, the information of people with abnormal test results was pushed to the Qilihe District Joint Defense Office, and the District Joint Defense Office informed the community at the first time to inform the relevant personnel to wait for transshipment. At 1 o’clock on November 24, the staff of Lanzhou Nuclear Huaxi Laboratory mistakenly entered the list information of individuals with abnormal nucleic acid detection into the negative personnel information package and uploaded it to the work system, so that the health code of individual persons to be transported showed that the nucleic acid detection was negative.

"The occurrence of this incident has interfered with the normal production and life of the masses and the prevention and control of the epidemic, exposing that Lanzhou Nuclear Huaxi Laboratory is not strict with the management of staff and the audit is not in place. We will seriously deal with Lanzhou Nuclear Huaying Laboratory in accordance with relevant laws and regulations. " The notice said.

In fact, the abnormal event of Lanzhou nucleic acid test results is not the first time that Shenzhen nuclear gene has problems. On April 14th, 2020, Jinan Huaxi Medical Inspection Co., Ltd. (hereinafter referred to as Jinan Huaxi) was warned and fined by Jinan Municipal Health and Health Commission for failing to put infectious medical wastes in special packaging. In January, 2021, Xingtai City, Hebei Province held a press conference on the prevention and control of COVID-19 epidemic, and reported that the nucleic acid test results in Longyao County were falsely reported. The company involved was Jinan Huaxi. Jinan Huaxi is also indirectly 100% owned by Shenzhen Nuclear Gene.

According to the official report, Longyan County entrusted Jinan Huaxi Medical Laboratory, a subsidiary of Jinan Huaxi, with the second round of all-staff nucleic acid testing. Zhai Moumou, an employee of the company, reported to the health department of Longyao County that all the results were negative when the samples were not tested and the number and results of the tests were unknown, and then reported that there were positive samples. The laboratory was suspended from Covid-19’s nucleic acid detection business, and Zhai was also criminally detained by the police on suspicion of endangering public security by dangerous means.

Recently, many online articles have pointed the finger at the founder of Shenzhen Nuclear Gene, Zhang He, and Zhang Shan, who is a supervisor of several subsidiaries of Shenzhen Nuclear Gene. The company was caught in the whirlpool of public opinion for a time.

The reporter visited Shenzhen Nuclear Gene Headquarters on the spot.

What is the latest situation of Shenzhen nuclear gene in the whirlpool of public opinion? On the afternoon of November 28th, national business daily reporter visited the headquarters office of Shenzhen Nuclear Gene in Nanshan Zhiyuan, Nanshan District, Shenzhen.

In the office where the registered address of the company is located, the front desk wall is engraved with "Shenzhen Nuclear Huaxi Medical Laboratory" (hereinafter referred to as Shenzhen Nuclear Huaxi). Enterprise investigation shows that Shenzhen Nuclear Huaxi was established in July 2015 and is also 100% controlled by Shenzhen Nuclear Gene. The poster on the wall introduces that in February, 2020, Shenzhen Nuclear Huaxi became one of the first batch of third-party COVID-19 nucleic acid testing institutions approved by Shenzhen Health and Health Commission, and the other approved third-party COVID-19 nucleic acid testing institution was Shenzhen Huada Testing Center.

The reporter noticed that the company’s publicity column said that "the number of people tested nationwide has exceeded 700 million, and the sample detection has zero error".

In the office, the company staff are still working normally, and people come in and out from time to time, and some staff members pull boxes of protective articles such as isolation gown to the open space in the office. After the reporter indicated the interview demand, two front desk staff refused the interview on the grounds that "the leader is not in the company today and no one is receiving him". The above-mentioned staff also said, "I don’t know when the leaders will come back. They do have various things outside, including epidemics all over the country, and there are many things to be busy."

A property manager of the office building told reporters that the person in charge of Shenzhen Nuclear Gene usually comes to the office at around 10: 00 every morning. He also met the person in charge of the company this morning, but the person in charge left the office this morning. In another company office in the park, the reporter failed to enter, and the company asked the security guard to take a message and refused to be interviewed.

Who is the founder of the company, Zhang Hezhen? On the CCTV talk show titled "Beyond" in March, 2018, Zhang Hezhen introduced the origin of his own name. His father was a middle school teacher of science and engineering, and named Zhang’s three brothers nuclear, electronic and atomic respectively.

An article on the wechat WeChat official account of "Nuclear Gene Group" described in detail the development track of Zhang He and the company: In 1990, Zhang He was admitted to China Medical University to study DNA identification. After graduation, he came to work in shenzhen public by introducing high-tech talents and organized the earliest DNA identification center in China. Later, Zhang Hezhen left the Public Security Bureau to start his own business. In 2000, he established Shenzhen Hongshi Villa Decoration Company (now known as Shenzhen Hongshi Decoration Engineering Co., Ltd.), and then withdrew from the list of shareholders in 2018. Zhang Hezhen also entered the field of real estate consulting and brokerage, and jointly founded Shenzhen Hongshi Real Estate Consulting Co., Ltd. with Ba Ying, but the company has been cancelled.

In 2012, Zhang He founded Shenzhen Nuclear Gene. Enterprise investigation shows that the top two shareholders of the company, Zhang He and Ba Ying, hold 64.7351% and 12.1378% respectively. The registered capital of the company is 37.07 million yuan, 62 companies have been invested abroad, and 55 companies are in existence and in business. In 2013, Shenzhen Nuclear Gene established Guangdong Huaxi Forensic Material Evidence Judicial Appraisal Institute in Shenzhen and established a research institute in Shenyang. Zhang Hezhen has 30 affiliated enterprises and served as the legal representative of 22 of them.

Recruiting nucleic acid samplers in Hohhot can cost more than 10,000 yuan a month.

According to many media reports, after 2013, Shenzhen Nuclear Gene expanded at the rate of setting up three or four inspection laboratories and forensic laboratories every year.

In an article published by WeChat official account, the wechat of Nuclear Gene Group, I wrote: "In order to make genetic technology enter the life of every ordinary person from the unreachable peak of science and technology, people can enjoy efficient, accurate and scientific genetic testing services near their homes, and finally realize that genetic testing is as popular and convenient as physical examination. In 2016, Nuclear Gene launched the’ Hundred Brands and Ten Stores’ program in the genetic industry."

According to the introduction of Shenzhen Nuclear Gene, the so-called "100-brand" means that 100 laboratories have been laid out nationwide and obtained national licenses; "Wandian" means that there are 10,000 "nuclear gene health centers" in China.

In official website of Shenzhen Nuclear Gene, the words "Gene has come, and Nuclear invites you to join the gene industry" are very striking. Click on the column of "Investment Center" of WeChat official account, a nuclear gene group, and it says "Join the genetic testing, unlimited money". The key words below are also very straightforward: "No joining fee, zero foundation and key state support".

In the program "Beyond", Zhang Hezhen talked about the concept of "gene hut", which was used to popularize genetic knowledge and provide services, and said that more than 500 houses had been opened at that time, with the goal of opening 10,000 houses. In the investment promotion page, joining a gene hut only needs a 10㎡ storefront and 1-2 operators. After being trained by nuclear genes, they can engage in health management consultation, DNA paternity and genetic testing sampling and consultation.

Shenzhen Nuclear Gene held a large number of promotion activities in the rapid development stage of agents. Official website, the company, shows that it regularly holds a promotion meeting every month in 17 major first-and second-tier cities, with Zhang Hezhen giving a lecture on profit model, marketing channels and case analysis. However, the above-mentioned joining information was mainly released before 2019, which was not related to COVID-19 testing business.

Shenzhen Nuclear Gene claims that the company has obtained 29 medical and judicial licenses approved by the state, and has more than 300 cutting-edge technology and management staff including nearly 200 doctors, masters and returned students. It has 29 independent laboratory platforms, including 19 forensic laboratories and 10 medical laboratory.

According to the reporter’s incomplete statistics, since 2022, Shenzhen Nuclear Gene has opened more than ten subsidiaries named after "Medical Laboratory Co., Ltd.", including Quanzhou Nuclear Huaxi Medical Laboratory Co., Ltd., Beijing Nuclear Huaxi Future Medical Laboratory Co., Ltd., Xiamen Nuclear Huaxi Medical Laboratory Co., Ltd., Yinchuan Nuclear Huaxi Medical Laboratory Co., Ltd. and so on. These medical laboratories may mainly provide COVID-19 nucleic acid detection services for various places.

On a recruitment APP, the reporter searched for the keyword "Nuclear Huaying", showing that there are 10 recruitment entities, and the publisher is "Shenzhen Nuclear Gene Technology Co., Ltd." and its subsidiaries, with a total number of positions exceeding 300. Among them, Shenzhen Nuclear Huaxi Medical Laboratory Co., Ltd. has released more than 200 posts, involving first-line posts such as nucleic acid sampler, laboratory inspector and freight driver, as well as system posts such as quality inspection, data and salary, and even Tik Tok anchor, whose working locations involve more than ten first-and second-tier cities such as Shenzhen, Shanghai, Shenyang and Nanchang.

Original title: In-depth Report on Semiconductor Industry (Chip and Equipment Materials in Subdivision)

　　Shanghai Disneyland’s ban on bringing food and rummaging through bags has attracted more and more consumers’ attention.

　　On August 12th, CCTV financial reporters visited Shanghai Disneyland.

　　The reporter visited Shanghai Disneyland

　　The phenomenon of bag rummaging still exists.

　　On the morning of August 12, the reporter bought the tickets for Disney on that day through the computer. During the purchase, there was no obvious indication that food was prohibited.

　　CCTV financial reporters clicked on the pre-departure instructions for entering the official website, and did not see any instructions on the prohibition of bringing food. Only when you buy tickets on your mobile phone can you see the relevant reminders at the end of the page.

　　Later, the reporter came to Disneyland and walked around the door, but he didn’t see any signs that it was forbidden to bring food into the park.

　　After entering the door, the first checkpoint is to check your belongings. The reporter saw that each inspection desk was equipped with two or three staff members, and tourists put items on the inspection desk in turn for the staff to check.

　　The staff opened the reporter’s backpack and said, "Water can be brought, but bread can’t be brought."

　　Security personnel: Food can’t be brought, but water can be brought. You can eat bread here. No food is allowed. Don’t bring it next time.

　　After checking the reporter’s backpack, the staff put the bread in the reporter’s bag again and told them not to bring it next time.

　　Subsequently, another reporter also entered the security checkpoint, and the staff did not object to the biscuits and water carried by the reporter. But when the reporter asked if they had the right to search the bag, the staff told the reporter that this was a paradise rule.

　　CCTV Financial Reporter: Do you have the right to search for packages? Can I just open it for you?

　　Security inspector: No, I can’t see below.

　　Security personnel: You must search. This is the rule of the paradise. If you want to do this, take out the things in your bag yourself.

　　Compared with the previous ban on bringing bread, biscuits and other foods, it seems that the inspection has been relaxed now, but many tourists think that there is an invasion of privacy in the case of staff searching bags.

　　Visitors to Shanghai Disneyland: I don’t think it is particularly reasonable, because there are some privacy things after all.

　　Visitors to Shanghai Disneyland: Personally, I think you are not a law enforcement officer. Relatively speaking, such words are a serious violation of personal privacy.

　　In addition, during the visit to the park, the reporter saw that there are dining cars and shops selling food and drinks every few meters. The price of an ice cream is in 40 yuan, and the price of a bottle of coke is in 20 yuan.

　　In the restaurant in the park, the reporter saw that many tourists came to eat at mealtime. The price of a set meal is around 100 yuan, and a stylish drink needs 88 yuan. Take a family as an example, the price of a lunch is about in 300 yuan.

　　Visitors to Shanghai Disneyland: The price in the park is too expensive. If you don’t allow food to be brought, but the price inside is closer to the people, this problem should be solved.

　　Lawyer: Shanghai Disneyland searched the bag for inspection.

　　Invasion of privacy

　　Disney does not allow tourists to bring food into the park, and it is necessary to open tourists’ backpacks before entering the park to check the items carried by tourists. Are these legal?

　　In response to the ban on bringing your own food, Shanghai Disneyland responded to CCTV financial reporters, which is consistent with other parks in Asia.

　　CCTV financial reporters learned that Disney currently has six top family holiday destinations in the world. The three Disneyland parks in the United States and France do not prohibit consumers from bringing food into the park, while China and Japanese Disneyland, as Asian countries, prohibit bringing food.

　　Wang Longjie, lawyer of Shanghai Wanda Law Firm: Disney in different regions applies different standards, which is a double standard in itself. Is it legal for Disney to make this rule? This is not the decision of a certain enterprise. At present, this case has been filed by the People’s Court of Pudong New Area in Shanghai, and it is under trial. Whether it is legal or not, the court’s ruling will tell us the answer.

　　The reporter learned in the interview that an important reason why tourists bring food into the park is the high food price in the park. For example, the cost of a locker in the park is 80 yuan, and it costs 20 yuan to buy a bottle of coke. The price in the park is almost 5-10 times that outside.

　　Wang Longjie, lawyer of Shanghai Wanda Law Firm: Consumers have the right to choose consumption and services, and he can choose goods. Now, this rules out the behavior of consumers bringing their own goods to consume, and it can only make consumers accept the catering services provided by Disney in disguise. This behavior of Disney actually violates the Consumer Protection Law.

　　Lawyers believe that when we take public transportation such as plane, train and subway, we need to cooperate with the security check to check the things we carry with us. This is because in the face of public safety, personal privacy needs to be given some concessions, and it is supported by corresponding laws and regulations.

　　But Shanghai Disneyland checks tourists’ bags in order to prevent bringing their own food. Wang Longjie believes that this violates consumers’ personal privacy.

　　Wang Longjie, lawyer of Shanghai Wanda Law Firm: This kind of inspection can only be done if it is authorized by law. Disney is only a commercial enterprise, and it cannot have any power beyond the law. It is an act of inspection and search in disguise, which is an act of infringing on the privacy of others and is also prohibited by law.

On November 9th, according to the information of National Health Commission official website, National Health Commission, the State Administration of Traditional Chinese Medicine and the State Bureau of Disease Control and Prevention have jointly issued the "Tenth Five-Year Plan for National Health Informatization" (hereinafter referred to as the "Plan"), proposing that by 2025, a unified, authoritative and interconnected national health information platform support and guarantee system will be initially established, and the full coverage of public medical and health institutions and the national health information platform will be basically realized.

Among them, the "Planning" mentioned that "in 2025, every resident will have a dynamically managed electronic health record and a fully functional electronic health code". This content has attracted attention. On November 10th, Wei Zining, Dean of Management Development Research Institute of Beijing Sanyi Zhiku Hospital, said in an interview with Red Star News reporter that the health code mentioned in the Plan is not a health code or a travel code set to deal with the COVID-19 epidemic, but actually it is more like a personal electronic health record of residents. Such a health code is also set to make use of big data and the Internet to better serve residents, and people do not have to worry too much about privacy, travel leakage and other issues.

National Health Commission, the State Administration of Traditional Chinese Medicine and the State Bureau of Disease Control and Prevention have jointly issued the "14 th Five-Year Plan for National Health Informatization"

Hot discussion on the whole network:

Residents have fully functional electronic health codes.

Some netizens are worried that privacy will be leaked.

The Red Star journalist noted that the "Planning" has deployed eight main tasks for the future, namely, intensive construction of information infrastructure support system; Improve the national health informatization standard system; Deepen the "Internet+medical health" service system; Improve the system of big data resources for health care; Promote digital health integration and innovative development system; Expand the basic information security service system; Strengthen the application system of health statistics investigation and analysis; Consolidate the network and data security system.

In addition, the "Planning" also puts forward eight priority actions: sharing and sharing three years of hard work; Healthy China construction (action) supporting action; Demonstration action of smart hospital construction; Intelligent service action for key populations; Intelligent monitoring and response actions for drug supply guarantee; Digital public health capacity improvement action; "internet plus Traditional Chinese Medicine Health Service" action; Data security capability improvement action.

In recent years, the word "health code" has become a high-frequency word in life. After combing, Red Star journalists found that the word health code was mentioned five times in Planning. Among them, when talking about the overall improvement of emergency response capacity for epidemic prevention and control, the Plan mentioned "promoting the unification of health code policies and standards, realizing the national sharing of nucleic acid test results and vaccination information in Covid-19, ensuring the orderly travel of the masses, and efficiently coordinating epidemic prevention and control and social and economic development." In terms of development goals, the Plan proposes that "every resident has a dynamically managed electronic health record and a fully functional electronic health code".

In addition, the Plan also mentioned that in the main tasks of the 14 th Five-Year Plan for National Health Informatization, the issue of health code was also mentioned in the part of promoting the digital health integration and innovation development system, sharing and sharing the three-year attack, and improving the digital public health capacity. The Plan mentions that it is necessary to "gradually realize the multi-code integration of electronic health code, medical insurance settlement code and financial payment code", and to "take the popularization and application of residents’ electronic health code as the starting point, establish the only main index for residents with ID card numbers as the main index and other certificate numbers as the supplement, and promote" one code for universal use ". In addition, the Plan also mentions "strengthening the use of health code standards, strengthening the implementation of coding and transcoding rules, and promoting mutual recognition and one code communication".

Red Star News reporter noticed that netizens are particularly concerned about the article "every resident has a dynamically managed electronic health record and a fully functional electronic health code". Some netizens have doubts and asked, "Is this health code a trip code?" "Will setting such a health code violate my privacy?"

On July 6, 2022, in Yuncheng, Shanxi Province, a resident scanned the code at the nucleic acid detection point in Xinjiang County for nucleic acid detection. According to vision china

Expert interpretation:

Like mobile electronic health records.

Don’t worry too much about privacy leaks.

For all kinds of questions raised by netizens, Wei Zining, dean of the Management Development Research Institute of Beijing Sanyi Zhiku Hospital, told Red Star News reporter that this health code was not built during the COVID-19 epidemic, and it was not a trip code. The health code in Planning was more like a mobile electronic health record of residents.

"The health code mentioned in the plan is more like an electronic file of residents, which may contain health information of everyone from birth to death. Such as vaccination, case information, family genetic diseases, etc. " Wei Zi-ning said that the health code we often talk about now is actually set up to cope with the epidemic situation in COVID-19. We can see whether the residents have done nucleic acid, whether they are negative or positive, and how many days they have done it. The health code mentioned in the Plan should have a much more comprehensive function than the (current) health code.

Wei Zining said that the setting of the electronic health code mentioned in the Plan can better help doctors understand the personal health status of patients. "Your past medical history and medical records may all be in this health code. When you go to see a doctor, the doctor can fully grasp it in order to make a more scientific diagnosis of the patient."

Wang Chenguang, a professor at Tsinghua University Law School and executive vice president of China Health Law Society, has similar views with Wei Zi-ning. Wang Chenguang told the Red Star journalist that the electronic health code mentioned in the Plan is actually a comprehensive personal health information file, which is used by China to better serve residents’ health by using the Internet and big data.

"At present, the functions of this health code are not completely determined. It may include some functions of this health code currently used to fight the COVID-19 epidemic, but this part of the function is only a small part of it." Wang Chenguang said that with the development of the times, the mobility of people is also increasing. If you have such a health code, it means that everyone’s health information is carried with you. For example, if there is an accident or illness in any area, doctors can know this person’s historical health information through this health code, so as to give the most accurate treatment.

For some netizens who are worried that the health code will reveal personal information, both experts said that this kind of worry is actually unnecessary. "This health code is placed in your personal mobile phone every day. If you don’t show it to others, you should not be able to find it at will, including doctors. Only after my consent, in the case of medical treatment and vaccination, relevant information will be displayed." Wei Zining said.

Wang Chenguang, on the other hand, said that people’s worries about the disclosure of personal privacy are not unreasonable, but there is no need to worry too much. "When building the health code, the relevant institutions definitely need to collect and store personal health information, but this behavior is to protect the health of residents, not to infringe on the privacy of citizens."

Wang Chenguang said that our society is now an information society, and the appearance of this kind of health code is inevitable, which is a normal use of information. Relevant institutions will also prevent people with ulterior motives from maliciously invading when building, and laws and regulations will also regulate the use of health codes.

Guo Tao, Deputy Director of National Plant Aerospace Breeding Engineering Technology Research Center:Our country has been carrying out space breeding for more than 30 years, and has carried out a lot of research on major food crops, cash crops and trees. According to incomplete statistics, more than 200 varieties have been cultivated and popularized in production. In the southern region, super rice bred by space flight can completely achieve an yield of more than 1,000 kilograms per mu in two seasons in a year, which also plays an important role in the stable production of grain in our country and the supply of high-quality agricultural products.

As China Space Station enters a new stage of application and development, the related scientific experiments of space breeding in China will be further advanced.

Guo Tao, Deputy Director of National Plant Aerospace Breeding Engineering Technology Research Center:We not only say that we should put seeds in the space station, but also consider some exposed radiation devices outside the space station to promote the genetic improvement of plants more effectively. Aiming at the needs of the industry, we will vigorously cultivate varieties of new farming methods that meet the needs of future industrial development and meet people’s requirements for high-quality life.

The reporter learned from the seminar that China Manned Space Engineering Office will use manned space resources to promote the development of local characteristic industries around the fields of space breeding, space science popularization and space-grade food, and further give play to the comprehensive benefits of China’s manned space engineering.

Yang Liwei, deputy chief designer of China’s manned spaceflight project:Through our many platforms and recruitment, this scientific research platform of the space station is not only breeding in space, but also carrying out a large number of scientific experiments in many aspects in the future through aerospace medicine, materials and biology. Through these scientific experiments, I hope to produce a lot of scientific achievements and provide a good boost for our society and the development of economy, science and technology.

Overseas Network July 4th The first Apple Store direct store in Taiwan Province was grandly opened last Saturday (1st). Some fruit powder found that the receipt of the Apple products purchased in the Apple Taipei 101 direct store said no return, which triggered a discussion among netizens on the return policy of the Apple direct store.

According to the purchase policy of Apple Direct Stores in Taiwan Province announced on Apple’s official website, as can be seen from the webpage, it is indeed clearly listed that "all Apple and Beats products purchased from Apple Direct Stores in Taiwan Province are not allowed to be returned or exchanged."

In addition, "if you are not satisfied with the other products you bought, please return them together with the original receipt and original packaging within 14 days after the purchase date." The announcement policy also pointed out that if you buy a non-Apple original product, that is, a third-party product, if it is found to be defective afterwards, you can return it within 14 days of the purchase date. If the product is intact and undamaged, you can apply for a return or refund.

In this regard, Taiwan Province media verified with Apple’s official, and Apple responded that Apple Store has made corresponding policies and measures for different regions. At present, the sales policies of Apple’s direct stores in Taiwan Province are subject to official website’s announcement. In addition, if you purchase all Apple products online through Apple official website in Taiwan Province, you will enjoy 14-day return service.

The official customer service also suggested that when you buy the on-site inspection machine, you must check it very clearly. If you find any defects or faults, you must ask for replacement immediately. If the machine has been inspected at the scene and the payment is completed, it is found that the purchased product is defective after returning home, and the Apple Direct Store will not accept the return.

However, it can be seen from Apple’s official website that in the mainland direct stores, it enjoys a 14-day return guarantee. This shows the differences in Apple’s sales policies, and this kind of differential treatment also makes many Taiwan Province fruit fans feel chilling.

According to overseas reports, Taiwan Province’s first Apple Store opened in Taipei 101 at 11: 00 am on July 1, attracting Taiwan Province’s "fruit fans" to make a pilgrimage in the morning. Some people even waited in line three days ago, and the crowds were full and endless, with at least 700 to 800 consumers queuing in the morning.

The Apple Direct Store in Taiwan Province is its 497th branch in the world. This time, the Apple Direct Store in Taipei takes "Tree" as the theme, and presents "the beauty of meeting" with huge paper-cutting art, citing the traditional custom of Taiwan Province: in the past agricultural era, every village in Taiwan Province always prepared a pot of tea under the banyan tree at the head of the village, so that travelers passing by could drink it when they were thirsty, and after a short rest, they continued to embark on a brand-new journey. This time, Apple cited the local tradition in Taiwan Province, hoping that Taiwan Province people can exchange ideas, have fun and start again here.

According to the report, after the opening of Apple Direct Store in Taiwan, the biggest benefit for Apple users is "more convenient maintenance". In the past, Apple only had distributors in Taiwan Province and no direct stores. If the products had to be repaired, the distributors had to send them to Singapore for repair. Even if it took only 3-5 working days from receipt to delivery, it would take at least two weeks. In addition, in the past, there was no public price for the maintenance of Taiwanese apples. If they were sent to dealers, they could still have reasonable prices. However, if they were sent to general communication companies, the prices of many parts were uneven and the quality of maintenance was difficult to guarantee, which made Taiwan Province consumers quite troubled.
