"Far ahead" Tan Sir’s experience: Thoughts on M5 Zhijia Edition

   When intelligent driving covers complex urban roads from expressways and loops, high-precision maps are far from being used. Facing the changing road conditions every day or even every hour, it is necessary to get rid of high-precision maps, which is also the key for manufacturers to win.

  So, there is such a dialogue — —

  "You don’t pay attention to the traffic lights when driving, so what do you pay attention to?" "You said that he didn’t pay attention to the head shape, but he didn’t pay attention to safety, which would be wrong!" Sir Tan, an old traffic policeman who has served the police force for more than 30 years, has always broken his heart for everyone’s driving safety. The good news is that Mr. Tan’s heart disease for many years has been completely cured! What is the panacea so effective? The answer is the "double wisdom ceiling" that has just been officially listed — — AITO asks the world M5 Huawei Advanced Intelligent Driving Edition.

  HUAWEI ADS 2.0, the high-level intelligent driving level of zero takeover impressed Tan Sir.

  In the actual test drive experience in Shanghai, Yu Chengdong personally drove the M5 version of Zhijie, carrying Mr. Tan to experience HUAWEI ADS&ensp in the most prosperous and complicated urban area of Magic Capital Shanghai;   2.0 advanced intelligent driving system, the perfect performance of the M5 intelligent driving version shocked the safety experience officer Tan Sir. Tan Sir was deeply impressed by the high-level intelligent driving level of zero takeover, and even shouted the classic golden sentence — — "Far ahead".

  At the intersection where people and vehicles are mixed, the M5 Intelligent Driving Edition will automatically recognize the traffic lights, and can read the remaining time information of the traffic lights to start and stop autonomously. When vehicles in other lanes intrude, take the initiative to yield to ensure safety. After the high-order intelligent driving pilot is started, the M5 intelligent driving version can easily realize unprotected left turn, U-turn and road avoidance in urban areas, the steering control is very linear, and the details are quite in place.

  Excellent hardware and software blessing, excellent actual performance.

  Tan Qiao and Yu Chengdong talked about the safety topic of intelligent driving during the test drive, and Tan Sir felt sorry for HUAWEI ADS    2.0 is like an old driver with millions of kilometers of driving experience. He is completely autonomous and has delicate and steady driving skills, which can always ensure driving safety. Yu Chengdong said that the excellent performance of the M5 Intelligent Driving Edition is the foundation of excellent software and hardware and the blessing behind Huawei’s self-developed algorithm.

  Based on the fusion of BEV(Bird Eye View) network to identify white list obstacles such as cars and people, GOD(General Obstacle    Detection general obstacle detection) network, which can identify a variety of objects outside the general obstacle white list. Based on multi-sensor fusion perception system, combined with road prediction neural network, it can realize traffic element association, road topology reasoning, navigation map matching with real road, etc., and realize that cars can "see" complex road conditions and drive with or without maps.

  When vehicles enter and leave the tunnel, they can identify the special obstacles inside and outside the tunnel, and they can not be afraid of light and shade changes. According to the actual road conditions, they can give early warning and make deceleration or avoidance actions, effectively preventing accidents and greatly improving safety.

  It is worth mentioning that with the continuous increase of the mileage of high-level intelligent driving, Wenjie M5 Intelligent Driving Edition continues to learn advanced with cloud big data AI training, and the ability of high-level intelligent driving will become stronger and stronger, which can cope with more complicated road conditions.

  Huawei’s first intelligent driving interactive game algorithm perfectly solves the problem that intelligent driving encounters difficult road conditions in complex scenes where people and vehicles are mixed, solves the problem of taking over more than 70% of interactive scenes, shortens the transit time by 40%, and makes intelligent driving behave more like an "old driver".

  The perfect high-level intelligent driving performance of the M5 intelligent driving version in the world conquered the safety experience officer, Sir Tan. Before the test drive is over, Mr. Tan said that he has put the M5 version of the intellectual drive in the shopping cart, which is enough to show that Mr. Tan is interested in the M5 version of the intellectual drive and HUAWEI    Absolute recognition and full trust of ADS 2.0 advanced intelligent driving.

British hackers will be extradited to the United States for trial if they invade US military computers (Figure)


Mckinnon, a 42-year-old unemployed computer worker, invaded the US military computer.


  BEIJING, July 31 (Xinhua)-A British computer hacker is suspected of illegally invading the computer systems of the US Navy, Army and Air Force and the Ministry of National Defense in his London apartment, causing damage. The British authorities wanted to extradite him to the United States for trial. He appealed, but the London court ruled that he lost the case on the 30th. It is expected that he will be taken to the United States in a short time.


  According to Sing Tao Global Network, McKinnon, a 42-year-old unemployed computer practitioner, was accused of successfully hacking into 97 computers of the US military and the Ministry of National Defense from 2001 to 2002. Some people described this as the largest hacking incident into the military computer system in history, which made the US authorities extremely embarrassed.


  The chief prosecutor pointed out that the invasion paralyzed the military region responsible for protecting the capital Washington and the New Jersey Naval Ammunition Station. In addition to the military and the Ministry of National Defense, the computer systems of NASA and several private institutions were also invaded by him. The authorities estimate that the financial losses caused by these actions amount to 900,000 dollars.


  Mckinnon will face eight counts of computer fraud in New Jersey and Virginia. If convicted, he will be sentenced to a maximum of 10 years in prison and a fine of $250,000.


  Mckinnon, whose net name is "SOLO", defended himself in the British court, claiming that he was only trying to expose the loopholes in the computer security system of these departments and looking for evidence about UFOs.


  Mckinnon wrote on the website of the British newspaper The Guardian last year: "I am an possessed man." He claimed that he spent a year sitting in front of the computer for an average of eight hours every day, invading the computer system of the US military, not washing and grooming every day, and binge drinking beer and smoking marijuana. He claimed that he had successfully found some photographic evidence to prove the existence of alien spaceships and the names and ranks of "non-human officers".


  The prosecution accused him of deliberately using these actions to try to blackmail the US government. Mckinnon once left a message in a computer of the U.S. military, accusing the U.S. government of pursuing a foreign policy similar to government-sponsored terrorism.


  He was arrested in 2002, and the defense lawyer asked for a trial in Britain, because if he was extradited to the United States, he might be taken to a military court for trial, or even be held at the US military base in Guantanamo, Cuba.

The performance continued to increase, and the smart driving business ushered in overseas breakthroughs.

  Desai Siwei (002920)

  Event overview

  Desai Siwei recently released its 2023 annual report. In 2023, the company achieved an operating income of 21.908 billion yuan, a year-on-year increase of 46.71%, a net profit of 1.547 billion yuan, a year-on-year increase of 30.57%, and a net profit of 1.467 billion yuan, a year-on-year increase of 41.47%.

  Intelligent cockpit and intelligent driving with two-wheel drive, single Q4 gross profit margin was repaired from the previous month.

  On the revenue side, thanks to the two-wheel drive of intelligent cockpit and intelligent driving business, the company achieved revenue of 21.908 billion yuan, a year-on-year increase of 46.71%. Among them, 1) the intelligent cockpit business realized revenue of 15.8 billion yuan, up 34% year-on-year, higher than the industry level. We believe that the continuous high growth of cockpit business is mainly due to the volume of new products such as domain controllers and the expansion of overseas customers. 2) The smart driving business realized a revenue of 4.5 billion yuan, a year-on-year increase of 74%, mainly due to the large-scale volume of high-end smart driving.

  On the profit side, the company realized a net profit of 1.547 billion yuan, up 30.57% year-on-year, slightly lower than the growth rate of the income side, mainly due to the downstream price pressure transmission and the low gross profit margin (16.2%) of the smart driving business. However, in Q4 alone, the company’s gross profit margin was 21.54%, an increase of 2.83pcts from the previous month, showing an obvious recovery trend. In addition, the scale effect of the company began to appear. Specifically, the company’s management/sales/R&D expense ratio in 2023 was 2.3%/1.4%/9.1%, respectively, which was 0.3pcts/0.2pcts/1.8pcts lower than that in the same period of last year, indicating that the company has passed this expansion stage and started to enter the harvest period.

  The annualized sales of new project orders totaled over 24.5 billion, and the smart driving business ushered in an overseas breakthrough.

  According to the annual report, the annual sales of new project orders exceeded 24.5 billion yuan in 2023, of which the annual sales orders of new cockpit business projects exceeded 15 billion yuan, and new products such as the fourth-generation cockpit HUD and LCD instruments were designated by the project; The intelligent driving business exceeds 8 billion yuan, and the high-end intelligent driving platform has won new project orders from more than ten car companies, such as Ideality, Guangzhou Automobile Ai ‘an, Geely, Great Wall, Lotus, and Extreme Krypton, which is a strong guarantee for sustained growth in the next year. In addition, the company’s overseas business is progressing smoothly, with revenue of 1.64 billion yuan in 2023, up 48.1% year-on-year, higher than the overall level. It is worth noting that in addition to the cockpit business continuing to receive new orders, the company also obtained the smart driving business project designation of overseas core customers for the first time, and the smart driving business ushered in overseas breakthroughs, and the growth space was further opened.

  Investment advice:

  The company is the core target of automobile intelligence, with obvious advantages of card position and clear logic of subsequent growth. We are optimistic about its expansion from intelligent cockpit to intelligent driving, and its transformation from automotive electronics supplier to automotive intelligent enabler. We estimate that the company’s revenue in 2024-2026 will be 283.9/354.1/42.26 billion yuan, and the net profit attributable to the mother will be 2141/2860/3782 million yuan, respectively, maintaining the Buy -A investment rating. Due to the company’s leading position in the industry and the long-term space for automotive intelligence, we will give a net profit of 40 times PE in 2024, corresponding to a target price of 154.4 yuan in June.

  Risk warning: 1) The risk that the smart car market will not develop as expected; 2) The risk that the supply chain repair is less than expected due to the intensification of the epidemic; 3) The risk of increasing upstream chip shortage; 4) The risk that the company’s intelligent driving business is not progressing as expected; 5) Risk of intensified market competition.

Artificial intelligence is an opportunity and a challenge. Experts suggest that supervision should be strengthened from all aspects.

CCTV News:As an important part of Cyber Security Publicity Week, the 2023 Cyber Security Expo is being held in Fuzhou. The reporter noted that how to better develop the artificial intelligence industry attracted the attention of the participants. Many experts believe that although generative artificial intelligence can greatly facilitate and improve human life style, it also poses a new challenge to network security and needs to strengthen supervision from all aspects.

Experts pointed out that any technology has two sides, and there are a series of security risks hidden behind generative artificial intelligence, which pose new challenges to national security, social security, network security and data security.

In terms of security, experts pointed out that excluding human intervention, the security problem of artificial intelligence itself is also obvious.

China computer federation (CCF) Computer Security Professional Committee Member Degree:First, at the source, the data may be poisoned and polluted, so the original training data may have problems. Second, when training, there may be a big data discrimination algorithm in it, and it may not be a fair algorithm, which will lead to problems in the results. Thirdly, there will be a feedback mechanism in the final output stage, and the feedback mechanism may inject some malicious data or samples, which will also lead to the deviation of the answers obtained by this model.

So, how to deal with the hidden dangers of artificial intelligence? Experts said that this requires joint efforts from the supervision, practitioners and enterprises.

Li Xinliang, Expert of Guangdong Digital Government Network and Data Security Emergency Response Expert Group:In view of the security risks that AI may bring, I personally feel that it is necessary to speed up relevant legislation at the national level and formulate relevant industry standards as soon as possible. In addition, for AI practitioners, it is necessary to strengthen the corresponding training so that they can carry out it at the level of national laws and regulations when using AI technology. From the enterprise level, we must fully consider the compliance of collecting citizen information, and at the same time, we must strengthen the relevant actions of data protection in the transmission and storage of these collected data.

Geely star is the first to experience, and it is just outside and soft inside.

The "CMA architecture" planted in those years and together is now beginning to bear fruit in the brand-Xingyue, Xingrui, and now Xingyue L, which has set a record for the largest size of CMA.

Although it is named "Xingyue L", the design of this car is completely different from Xingyue. The latter tends to be dynamic and young, while the former pays more attention to maturity and stability.

Although the style orientation is different, the overall design language remains the same, which is also the characteristic of all models at present. A set of recognizable design allows unfamiliar people to recognize the brand without looking at the logo, which is very beneficial to the creation of brand image and the setting of product positioning.

The overall dimensions of Xingyue L are 4770*1895*1689mm and the wheelbase is 2845 mm.. It is reasonable to say that this size can be counted as a medium-sized SUV, but it is still called a compact SUV. One of the reasons is that the CMA architecture was originally aimed at compact models. As a result, the Xingyue L will look a bit "have no martial ethics" when compared with other compact SUVs in the future, similar to the previous Xingrui.

To sum up the shape of Xingyue L in a few words, there are probably: stable, thick, hard and strong. The headlights, grille, rearview mirror, window and wheel hub are all one size larger than the previous models. Although they lack the agility that young people like, they give people a solid and reliable psychological feeling, which is obviously a model for family use.

Matrix headlights are a bright spot, with 126 LED beads, which can control the switch and light and shade separately to ensure the brightness and lighting range, and at the same time, more lighting effects can be achieved through OTA in the later period.

Xingyue L’s car paints are available in six colors, including oyster white, aurora silver (as shown in the picture), basaltic gray, jet black and Mars red, as well as a distinctive "Cuiyu Blue", which is not blue or green, inspired by the mountains and mountains, and at the same time extracts the green texture of traditional porcelain and natural cuiyu. The cost of this car paint will be higher, and it may be available in limited quantities after listing.

When you open the car door, the little oppressive feeling brought by the appearance suddenly disappears, and the warm home atmosphere comes to you. The length of the triple screen across the center console is close to one meter, and the resolution of each screen has reached 1920X720.

This shooting vehicle is a test car, and the screen can’t be lit. The visual effect is quite good in the all-black state, and the overall feeling is very strong. At the recent Shanghai Auto Show, we saw the effect after lighting. The screen quality is very high, but the white theme still has a sense of separation. We look forward to the effect of the black theme.

The air conditioning outlets on both sides are directly opened on the huge black panel of the triple screen, which is a cost-free operation and of course brings good visual effects. Touched by hand, the edge of the opening is very round, and there is no cutting feel, which shows excellent workmanship.

The shape of the shift lever is similar to that of Xingyue and Xingrui, but the unlock key is cancelled, and the operation logic is the same as that of XC40. Shift the shift lever twice. The physical buttons in the air-conditioning control area have been preserved, which I praise.

Previously, the interior was decorated with palindromes, but Xingyue L was replaced with woven texture. There was a red and blue gradient stitch between the white stitches on the decorative board. At first glance, it was complicated, but at second glance, it added a little vitality to the interior.

The interior of this car is a combination of beige and red, while the Cuiyu blue model will be decorated with dark green and gold, which is more luxurious and mysterious. The roof is completely covered with suede material, and the cost is burning.

With such a large size, the rear space will naturally not disappoint, and the seat is wide, which provides good support for my whole body. The backrest angle can be adjusted, and the overhead space is about 15 cm. Because the electric seat of the vehicle can’t move, the passenger seat in the picture is actually in a backward position, which means that even if I have a more indulgent sitting position in the passenger seat, another passenger with a height of 180cm can still ride comfortably in the back row.

The luggage compartment has a great depth, but because the backrest of the rear seat is inclined, large items can’t be put in the depth. Open the lower cover of the luggage compartment, and there is a storage compartment below. After putting down the rear seat, the volume becomes very considerable, and the loading surface is only slightly inclined.

The vehicle being photographed is equipped with a 2.0T medium-power engine, with a maximum power of 218 HP and a maximum torque of 325Nm, which is between T5 and T4. It will be matched with a 7-speed wet dual-clutch gearbox and accelerate 7.9S at zero speed.

The Xingyue L will also have a 2.0T high-power engine with a maximum power of 238 HP and a maximum torque of 350Nm (which can be supercharged to 380Nm), matching 8AT and accelerating for 7.7 seconds. The performance gap between high and low power is so small that it is really rare. I wonder how much difference the price will be at that time.

It is expected that the price of Xingyue L will overlap with the mainstream joint venture compact SUV to a large extent, or even be cheaper. From this static observation, we can see that Xingyue L has obvious advantages over the joint venture SUV in terms of space, design, material selection and configuration. I look forward to the follow-up dynamic test drive and experience the strength of CMA architecture in mechanical and electronic aspects.

Quantum computer has just entered its "electron tube era"

  Although I have heard the name of quantum computer countless times, like all concepts with the word "quantum", most people don’t know it.

  The concept of quantum computer was put forward in 1980s, and it has been put into research and development for 20 years. So far, none of them has really gone out of the laboratory. But it is said that it will be very powerful. Google, IBM, Alibaba and many start-ups are competing to be the first to achieve "quantum hegemony", that is, to make quantum computers faster than traditional computers in a computing task.

  After a superficial understanding of the principle of quantum computer, you will find that it is not much different from the computer we are familiar with.

  Quantum computer: a quantum version of the computer

  "Don’t think of the quantum computer as a brand-new system, it is an extended version of the classic computer, imitating the classic computer everywhere." Professor Han Zhengfu, chief scientist of Anhui Wentian Quantum Technology Co., Ltd. and key laboratory of quantum information of Chinese Academy of Sciences of China University of Science and Technology, told the Science and Technology Daily reporter.

  Han Zhengfu said that the classic computer represents the number 1 or 0 by the voltage level, which is a bit.

  The quantum computer corresponds to a quantum bit (Q-bit), which may be an electron whose spin arrow is up or down, or a light wave that vibrates vertically or horizontally … …

  Traditional computing circuits are composed of various "logic gates", which correspond to various "quantum logic gates" of quantum computers. According to certain rules, the 0 and 1 of storage bits are changed.

  Han Zhengfu said: "The traditional computer is played like this: a row of memory bits is written with an initial value (such as 10011001). Next, several steps are performed, and at each step, the numbers in the memory are transformed into another set of numbers. Stop after the program and read the numbers inside, such as 00101010, which is the calculation result. " The same is true of quantum computers.

  The difference between quantum computers is that Q-bit is particularly flexible and not as rigid as Bit. It is both 0 and 1. For example, it is 60% 0 and 40% 1. This gives it super powers. You have to learn a little quantum mechanics to understand the mystery of Q-bit.

  Fuzzy and accurate Q-bit

  What do you mean, "it’s 60% 0 and 40% 1"?

  Take a refresher course in senior high school physics: Experiments at the beginning of the 20th century found that substances are too small to be measured accurately. Because measurement means interference, even if you only look at it. When the object is so small as quantum level, its state will be completely destroyed by observation. By the way, the "touch-and-break" effect is used in quantum communication. Using quantum to carry the password can make it possible for someone to eavesdrop on this password signal and will certainly be found out. ) This is called "uncertainty principle". The smaller things are, the more blurred they are. You go to measure the position of an electron, this time in Beijing and next time in Tianjin. We can only say that a quantum "has a high probability of being in Beijing", "has a high probability of spinning arrows rushing up" and "has a high probability of lying flat and vibrating" … …

  These probabilities can be determined by multiple measurements, although the reading of a single measurement is not necessarily.

  Therefore, quantum bits are fuzzy and accurate: when the same number is read, 0 is read, and sometimes 1 is read; But after reading it many times, the probability of 0 will tend to a constant value, such as 60%.

  Why is quantum computing faster?

  "In a traditional computer, a high voltage is superimposed on another high voltage, which is still a high voltage; The superposition of qubits is different. " Han Zhengfu said.

  Quantum bits store a vector, just like a clock, which corresponds to the probability.

  The hour hand can point to zero (the qubit reading is 100% 0) or to three (the reading is 100% 1). Or point to 1: 30 (50% is 0 and 50% is 1), or point to any angle.

  Traditional computers store "10011001".

  Quantum computers store "bells, bells, bells, bells". Please imagine a row of clocks hanging in the lobby of the hotel.

  In traditional calculation, 1 and 0 are superimposed to 1, and then a 1 is superimposed to get 0.

  In quantum computing, the superposition of "three points" and "zero point" is "1: 30", and then the superposition of "three points" results in "2: 15".

  Q-bit is more expressive than bit. A Q-bit can contain infinitely complex numbers. In this sense, "one is more than one". A Q-bit input transformation is equal to the transformation of multiple digits together, which is called "parallel calculation".

  When the potential of parallel computing reaches its limit, the computing power of quantum computer is 2 n ∶ 1 compared with traditional computer.

  But it should be emphasized that the results of quantum computers come from probability statistics. Quantum computer is different from tradition, it has to repeat the program again and again, and read it again and again (the result is different every time). Repeatedly, enough times (the reliability of probability exceeds 99.99999%), the ratio of each qubit to 1 and 0 is counted, and that is the required number. So when it comes to less complicated computing tasks, quantum computing may be slower than classical computers.

  Rainbow and zebra

  Before the advent of quantum computers, mathematicians were imagining to use the "rich connotation" of quantum bits to greatly reduce the calculation time. But so far mathematicians have only proved that quantum computing is much faster than traditional computers in two scenarios.

  The first is to crack RSA algorithm. RSA is the most commonly used encryption method at present, and its mechanism is the difficulty of factorization — — Multiplying two large prime numbers is very simple, but splitting the product into two prime numbers may take tens of thousands of years for the computer.

  Therefore, banks can send a number of thousands of digits publicly and master its two prime factors without worrying about someone working out these two prime factors — — Used to make private digital keys.

  But more than 20 years ago, Peter Shor proved that an algorithm based on quantum computer can easily decompose factors, which also greatly increased the interest of academic circles in developing quantum computers.

  Another possible application is "searching large unordered databases", or "looking for a needle in a haystack". Traditional computers can only compare targets one by one, while quantum computers can calculate in parallel. If the traditional computer time is t, the quantum computer time is "root t" The former takes 1 million hours, while the latter can be solved in 1,000 hours.

  In addition to the above two kinds of calculations, quantum computers are also expected to make great achievements in chemistry, pharmacy and other fields in the future. The reason is: unlike traditional computers, quantum computers are real analog computers, which can reproduce the real nature (physicist Feynman first pointed this out).

  The 0 and 1 of traditional bits are equivalent to black and white, and the "hour hand that can point at any angle" of quantum bits is equivalent to a full-color spectrum, which can display any color.

  If the traditional memory is zebra, the quantum memory is rainbow. The world is colorful, and it is certainly more direct and convenient to describe the world with rainbows.

  Just getting started

  Quantum is very fragile and will collapse easily.

  "To encode information in a very tiny thing, such as an electron or a nucleus, we must first isolate it and let it not work with the surrounding area. This subtle control is very difficult. " Han Zhengfu said.

  All kinds of quantum carriers are accompanied by unique difficulties, for example, photons are always advancing, and electromagnetic fields can’t control them, which is very troublesome to control. At present, researchers are probably experimenting with dozens of carriers: electrons, photons and ions in traps … …

  Han Zhengfu said: "The Key Laboratory of Quantum Information of the Chinese Academy of Sciences, which belongs to the Chinese University of Science and Technology, now has more than 50 associate professors, 150 doctoral students and nearly 30 postdoctoral students. There are many different groups in a team. Although the things studied are understandable to each other, there are specialties in the field, such as ‘ Make silicon ’ Some people will study the processes that the semiconductor industry cares about, such as exposure and cleaning; ‘ Do light ’ Research laser generators, oscillators, optical fibers and the like. "

  "Domestic research on quantum optics began in the early 1980s. There are many more people now, but they are still unpopular. Professionals are scarce. " Han Zhengfu said, "In fact, there are not enough talents in the world. So Google spent hundreds of millions of dollars to dig a team from the University of California, Santa Barbara, mainly studying superconducting quantum computers. "

  At present, major companies and research institutions are still improving the quantum bit quantity — — Strive for dozens of quanta to be stable at the same time, and don’t collapse too quickly. Superconducting machines cost millions of dollars to make the environment close to absolute zero. The engineering experimental machine is improving, but it is not known when it will be practical.

  Looking back at the first computer ENIAC in 1946, 18,000 electron tubes were used, which were glass tubes in which electrons were evacuated and flew. ENIAC weighs 30 tons and only calculates 5000 times per second. Without the semiconductor revolution more than ten years later, there would be no computers and mobile phones today.

  It should be said that the quantum computer has just entered its "electron tube era". (Science and Technology Daily reporter Gao Bo)

Dunhua News Network transformed consulting rooms in 14 hospitals and sent 38 bloggers for physical examination. Xiaohongshu launched a friendly action for women’s physical examination.

Such as writer Susan • Sontag wrote in Metaphor of Disease that everyone may face the disease, but in thousands of years of culture, some diseases have been labeled, making it difficult for people suffering from the disease to face themselves.

On the occasion of International Women’s Day on March 8th, Xiaohongshu Health launched the activity of "It doesn’t matter if there is something wrong", which helped more people to eliminate their sense of shame and anxiety through online topics and practical actions such as knowledge popularization and physical examination of 38 bloggers, and held the "It doesn’t matter meeting", which provided a place for public discussion on the topic of gynecological diseases that was originally shy. It is also to send care to women through the transformation of offline hospitals.

Susan • Sontag said, it doesn’t matter, the disease is just a disease, not a disaster from heaven, so don’t be ashamed to say it.

And Xiaohongshu also wants to tell you that there is something wrong with it, and it doesn’t matter. Action is the certainty of physical and mental health.

 From slogan to action "it doesn’t matter"

China Reproductive Health Research Report 2022 shows that among more than 3,100 women in 31 provinces and cities, 71% have gynecological symptoms such as irregular menstrual cycle, abnormal vagina and leucorrhea, but only 57.5% choose to see a doctor after gynecological symptoms appear.

Most of the shackles of women’s fear of illness and medical treatment come from the metaphorical "shame" and "fear" of illness. In addition, the uncertainty of diagnosis and the worry about future results have also discouraged many patients.

How to liberate from the metaphorical pressure brought by the disease, Susan • Sontag gave the answer: to get rid of these metaphors, we can’t just avoid them, they must be exposed, studied and exhausted.

In the online activity of "There is something wrong, it doesn’t matter", Xiaohongshu invited doctors as white coat friends to promote knowledge and ideas. And encourage more users to share the most authentic medical experience. Promote action with popular science, radiate the whole people from women, and reduce the anxiety and shame of ordinary people about diseases.

At present, there are 210 million exposures and 1.76w notes on the series of topics with # small problems and small methods. In addition to inviting many gynecologists and surgeons such as Dr. @Jojo to conduct popular science on women’s health; Xiaohongshu also launched the # It doesn’t matter action with 38 bloggers for physical examination. At present, many bloggers, such as @ Lahongshang @vivi Keaduo @ Sophie and Azhe, have shared the experience of gynecological examination, which is a name for gynecological diseases. Driven by them, more female users are willing to overcome shame and make changes for their health.

At the same time, on March 7th, Xiaohongshu also held a "Never mind meeting", inviting female characters from different fields, including doctors, writers, talk show actors, screenwriters and so on, to share their experiences and stories of coexistence with Xiaoxiao.

In gynecological examination, many women will be afraid of pain, and even wonder if they are too "melodramatic". In fact, individuals’ feelings of pain vary from person to person. As Si Wen said, we should respect the threshold of self-pain. Courageously expressing your pain during the examination is also a key step to face up to the disease.

From Online to Offline Friendly Clinic: A Closed Loop of Community Care

In recent years, the popularization of health knowledge is also driving the change of social concepts and promoting the public to face diseases and daily life with a correct attitude.

The fear and shame before seeing a doctor can be dispelled through popular science and experience sharing, but the discomfort in the actual examination is easy to leave a psychological shadow on women.

Ding Ding, director of the Department of Obstetrics and Gynecology of Huashan Hospital (Baoshan Campus) affiliated to Fudan University, told reporters that in terms of physiology, the discomfort caused by gynecological examination may be the feedback of most people, especially in the first or unfamiliar environment. "Some patients will also tell me that they don’t know what examinations to do, or what items to do in the routine physical examination of gynecology, and how often to do them … …”

It is not difficult to see that, in addition to professional medical advice, women also expect a warm and comfortable medical environment. Based on this, Xiaohongshu linked Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine, Huashan Hospital affiliated to Shanghai Fudan University (Baoshan Campus), Second Affiliated Hospital of Zhejiang University School of Medicine, Union Medical College Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology, Xiangya Second Hospital of Central South University, Henan Provincial People’s Hospital, Obstetrics and Gynecology Hospital affiliated to Fudan University (Red House), Hunan Provincial People’s Hospital, Shanghai Tongren Hospital, Shanghai Jiading Central Hospital, Chengdu Women and Children Central Hospital, Changsha Central Hospital (Red House)

Taking Huashan Hospital as an example, Director Ding Ding revealed that through the warm environment transformation, such as relaxing and encouraging floor stickers, gynecological examination posture wall stickers, "it doesn’t matter doll" decoration, and men’s stop to set up illustrations, we strive to create a "it doesn’t matter, relax and friendly clinic" to alleviate everyone’s fear and worry about gynecological examination and treatment and convey the warm concept of "it doesn’t matter, relax".

In order to optimize the experience of women’s physical examination, many warm-hearted copybooks have been posted in the waiting area of the gynecological clinic of Huashan Hospital, such as "Don’t worry, the little problems on your body will always get better slowly" and "If you don’t take good care of yourself, just say sorry to your body, and it will definitely tell you that it doesn’t matter."

The examination bed or chair in the clinic is the place where the patient’s fear concentration is the highest. In order to ease the tension, Xiaohongshu United Hospital posted the slogan "Never mind, relax" on the ceiling, "Speak out if you feel uncomfortable, and the doctor will accompany you" and other encouraging slogans.

In addition, for women’s concerns, such as "will gynecological examination hurt?" "How to check the posture?" There are also wall stickers and signs to help patients who enter the clinic for the first time quickly understand how to cooperate with doctors for examination. After the examination, "it doesn’t matter" accompanying dolls, including cute cartoon immune cells, uterus, stomach, etc., will be sent as long-term companionship to bring emotional value to patients.

It is worth mentioning that all warm-hearted and encouraging slogans come from the notes sharing of real users in Xiaohong Bookstore. In this process, Xiaohongshu realized the real concern for women from online to offline.

According to feedback from many hospitals, these improvements have been well received by many patients, and "fun" and "warm heart" are their most direct feelings. When waiting for treatment, many patients punch in and take pictures next to the floor stickers and wall stickers. A doctor admitted that she saw more patients’ smiles in the reformed clinic.

Xiaohongshu hopes that through the activity of "It doesn’t matter if there is something wrong", the public’s concept of diseases and women’s health problems can be changed, and the social value as a lifestyle platform can be highlighted.
