On May 15th, 2021, the Tianwen-1 lander landed in the southern part of the Utopia Plain of Mars. "Steady!" Jiang Mingjing, who stood in front of the TV, saw the news and stood up from his chair excitedly, holding his fist and cheering.

This report three months ago gave the reporter the idea of interviewing Professor Jiang Mingjing from the School of Architecture and Engineering of Tianjin University. During these three months, the reporter contacted him many times. As a result, Professor Jiang was either on a business trip or on his way. The background of several calls was the voice of the plane broadcast urging him to turn off his mobile phone. Professor Jiang’s busyness made reporters both surprised and helpless, and even had the idea of giving up the interview. Finally, these days, Professor Jiang returned to Tianjin to tutor graduate students, and the reporter seized this "hard-won" opportunity.

According to the report, in order to make Tianwen-1 land smoothly, Jiang Mingjing and his team spent two years simulating the construction of a Mars surface in Huailai County, Hebei Province. Mars, which is tens of millions of kilometers away from the earth, is an unknown field that needs to be explored urgently. It sounds impossible to "move" it to the earth, but Jiang Mingjing succeeded.

"My major is studying’ soil’, and all kinds of’ difficult soil’, such as Mars’ soil, are actually only a small part of my research content." Jiang Mingjing, a native of Jiangsu Province, speaks an authentic "soft language of Wu Nong". It never occurred to him that the tenderness and delicacy of the water towns in the south of the Yangtze River cultivated such a "hard-core" professor who was willing to deal with clods and stones.

"I studied undergraduate in 1982 and have been engaged in geotechnical research for more than 30 years." Looking at Jiang Mingjing’s resume alone, there are nearly one page: Professor, Doctoral Supervisor, Department of Civil Engineering, School of Architecture and Engineering, Tianjin University; bachelor’s degree and master’s degree in engineering from Hohai University in 1986 and 1993, and doctor’s degree in engineering from nanjing hydraulic research institute in 1996. In 1998, he was a special researcher at Osaka Institute of Soil Testing (now Japan Institute of Regional Site Environment); in 1998-2000, he was a special researcher at Kyoto University in Japan; in 2000-2003, he was a postdoctoral fellow at Lavalle University; in 2003-2004, he was a postdoctoral fellow at the University of Nottingham in the United Kingdom; in 2004-2006, he was a professor at Tongji University School of Civil Engineering. Since 2018, he has been a professor and vice president of the School of Civil Engineering of Tianjin University. Since 2010, he has served as the vice chairman of TC105 Committee of the International Association of Soil Mechanics and Geotechnical Engineering (reelected), won the National Natural Science Outstanding Youth Fund in 2009, and was selected into the National Million Talents Project in 2014. The 22nd Huang Wenxi Lecturer, a highly cited scholar in China published by Elsevier (2019 and 2020), and a top 2% scientist in the world published by Stanford University (2020). Experts from the Advisory Committee of the Ministry of Industry and Materials of the National Natural Science Foundation, experts from the Water Conservancy Association, experts from the National Natural Science Award, and young and middle-aged experts who have made outstanding contributions to the country.Enjoy the special post of the State Council government …

There is no need to say anything about the difficulty and gold content of a doctor more than 30 years ago. "At that time, the scientific research conditions were really bad, but the overall academic atmosphere was very positive. Everyone was engaged in research and everything was for scientific research." Jiang Mingjing said that he was lucky to meet a group of good teachers, which not only pointed out the direction for him, but also paved the way for his future scientific research. "When I was studying for a master’s degree, my teacher applied for an exam-free PhD and advanced placement for me, which was unprecedented. At that time, it was the only one in our school." During Jiang Mingjing’s Ph.D. study, the personal research funds totaled only 6,000 yuan in three years. "Although the price was low at that time, it was still far from enough. The teacher took out his funds from the National Natural Science Foundation and made a special application for me. A total of 45,000 yuan was spent on my research projects."

Shoulder the heavy responsibility and live up to expectations. It used to be a worldwide problem to simulate large voids in structural soil. Through analysis, Jiang Mingjing thinks that adding ice particles into soil materials at low temperature can artificially form large voids, and finally the structural soil can be artificially prepared. For this reason, he made a detailed experimental design, which was quickly recognized by the teacher. Although the idea is good, where can we find such a low temperature environment? Until Jiang Mingjing saw the cold storage in the school canteen. "I told the teacher that I have found a way to do the experiment, but I have to trouble you to say hello to the school logistics department."

I heard that Dr. Jiang was going to do the experiment, and the logistics readily "gave the green light". Nanjing in midsummer is as hot as fire, just like Jiang Mingjing’s mood of looking forward to the experiment. "In order to do a good job in the experiment, we made all kinds of preparations as comprehensively as possible, such as equipment, cotton trousers, cotton-padded jacket … that day, we were all very excited, but we were dumbfounded as soon as we entered." The young student was ready for the experiment, but forgot to be mentally prepared-the cold storage belongs to the canteen, and all kinds of "animals" are completely frozen inside. "It’s funny to think of it now, but at that time, several classmates and I were scared to have nightmares at night."

The cold storage experiment was successful, and Jiang Mingjing pursued the victory. "As long as I am engaged in scientific research, I will always be full of combat effectiveness." In order to get the data as soon as possible, he kept his hands on the experimental equipment. The air compressor was used in the experiment, which was very loud, especially in the dead of night. "I am used to it myself, that is, I suffered the residents nearby. At first, some people reported to the director. Later, when everyone knew that they were doing the experiment, they all expressed their support and understanding. I am very moved by it in retrospect."

Thick accumulation can make thin hair. Jiang Mingjing’s research achievements have attracted wide attention in the world. He has not yet graduated from a doctor, and many world-renowned universities have sent him warm invitations. At the beginning of 1998, he went abroad and worked as a postdoctoral researcher in Osaka Soil Experimental Institute, Kyoto University, Lavalle University, Manchester University and Nottingham University. In 2006, with the belief of serving the motherland, he resolutely returned to Tongji University to teach.

During the interview, the reporter always had a feeling that scientific research was not a career for Jiang Mingjing, but a belief, a belief engraved in his bones and willing to follow him all his life. Like, love, obsession … These are not enough to describe his persistence in scientific research. "When I first returned to China, the salary I got a month was only 1,500 yuan, and the rent was 1,850 yuan. For a long time, I was supplemented by my previous savings."

The firm belief has brought Jiang Mingjing to this day step by step, and time has proved it best. In recent years, with the continuous strengthening of China’s comprehensive strength, the scientific and technological strength is also making rapid progress. Aerospace, deep-sea exploration … These sophisticated fields have left more and more China and China footprints. During this period, Jiang Mingjing and his team also undertook project research in many related fields. "In addition to the Martian soil just mentioned, the deep-sea soil is also the focus of our research in recent years. Recently, we are preparing to carry out exploration, development and environmental protection of combustible ice and other resources in Hainan. "

Adhere to the problem-oriented and face the major needs of the country. As an expert and scholar in the field, Jiang Mingjing is well aware of our current shortcomings and weaknesses. "Some key technologies, important equipment, new energy technologies and other fields that are related to the urgent needs and long-term needs of the country must be in our own hands, so we must speed up the pace and work hard in this direction."

From Jiang Mingjing’s words, the reporter can strongly feel his urgent and expectant mood. From a grain of sand to a piece of soil, from a mountain to a star, Jiang Mingjing has always closely linked scientific research with actual needs. Knowing the heavy responsibilities, but having the courage not to be afraid of failure; I also know that the road is far, and I still have the enthusiasm to concentrate on research.

At the end of the interview, the reporter asked Professor Jiang if he expected to visit space in the future. The professor smiled and said, "Of course! Space travel has been realized, which is not far from us. " Only after the hardships of being down-to-earth can we have the courage to look up at the stars. Similarly, we also expect Professor Jiang Mingjing to lead us to see a higher and further world with his scientific research achievements.

Reporter: Can you briefly introduce your research field?

Jiang Mingjing: My research field is soil mechanics, which is an applied discipline to study the stress-strain or stress-strain-time relationship and strength of soil under the action of force. It is a branch of engineering mechanics. The research object of soil mechanics is soil and soil closely related to human activities, including artificial soil and natural soil, and groundwater closely related to the mechanical properties of soil. Soil mechanics is widely used in the design of foundations, retaining walls, geotechnical structures and dams, and is an important branch of engineering disciplines such as civil engineering, geotechnical engineering, engineering geology and energy engineering.

The development of soil mechanics should be initiated by Coulomb, which can be roughly divided into three historical stages: germination period (1773-1923), classical period (1923-1963) and modern soil mechanics (1963-present). Modern soil mechanics is a system based on macroscopic test results, continuum mechanics method and macroscopic constitutive theory of soil, and numerical analysis methods such as finite element and finite difference are used as tools, which plays an important role in geotechnical engineering practice.

At present, with the continuous expansion of geotechnical engineering in space, especially the promotion of deep, deep-sea and deep-space engineering ("three-deep engineering"), researchers and engineers need to face more complex environmental conditions (high geostress, high/low temperature, high water pressure, high vacuum, low gravity, strengthening chemical action, etc.) and difficult geotechnical materials, such as structural soil (temperature, pressure and force coupling, T-

Reporter: After successfully completing the Mars exploration project, what is your current research focus?

Jiang Mingjing: Recently, I am mainly engaged in deep-sea engineering projects. With the rapid development of China’s coastal economy, the proposal of the "Belt and Road Initiative" and the promulgation of the "Thirteenth Five-Year Plan" for the development of the national marine economy, offshore engineering projects such as offshore wind power, cross-sea bridges, submarine tunnels, offshore oil drilling platforms, seawater power generation, submarine pipeline laying, land reclamation and marine nuclear energy are constantly increasing, and offshore engineering projects are constantly growing and enriching. Ocean engineering has changed from traditional engineering projects to new engineering projects, and gradually developed from offshore and shallow sea to far sea and deep sea. The scale of the projects is also expanding, which puts forward higher requirements for the sensitivity, safety and durability of ocean engineering. A series of marine resources development is accompanied by many engineering and technical problems that need to be solved urgently, such as the safety of mining platforms and submarine optical cables, and the early warning and mitigation of natural disasters such as submarine earthquakes and seabed landslides are also the core issues of global concern.

Taking the exploitation of deep-sea natural gas hydrate resources as an example, the decomposition of hydrate will inevitably lead to the deterioration of the mechanical properties of the seabed, and improper exploitation methods may induce large-scale disasters (such as landslides) or the collapse of pile foundation platforms. How to choose a safe mining mode and area to reduce the impact of mining activities on the marine environment has become the primary problem in the actual hydrate mining process. It is very difficult to conduct on-the-spot investigation and research on the seabed, and it is expensive to simulate the deep-sea environment by laboratory tests. Therefore, we need to strengthen scientific research and comprehensively analyze the promotion of marine engineering to ensure its safety and feasibility.

Reporter: After listening to your introduction, we probably know the practical application of soil mechanics. What are your professional opinions on the future development opportunities in this field?

Jiang Mingjing: A new key field of soil mechanics has emerged-macro-micro soil mechanics. In the past 40 years, macro-micro soil mechanics has experienced germination, embryonic form and growth period, so it can be said that it is now welcoming the stage of accelerated development. I think the development opportunities of macro and micro soil mechanics in the future mainly include the following four aspects.

The first is to establish an efficient calculation method suitable for various geotechnical engineering problems. The research in this field may involve the physical and mechanical mechanism on the molecular or nanometer scale, and it also needs efficient coupling calculation methods. Because hundreds of millions or even trillions of particles need to be calculated, this will require high computing power. With the rapid development of computer technology, this contradiction will gradually weaken.

Secondly, according to the real working environment, the model of the difficult rock and soil mass of the "Three Deep Projects" and the relationship between the structural evolution and the macro-characteristics are established. The research in this field not only needs the micro-and micro-scale experimental technology to simulate extreme environments such as high/low temperature, high water pressure, high vacuum and chemistry, but also needs to solve the contradiction between the scale effect of representative units and the limitation of experimental testing accuracy, and also needs to develop the extraction, processing and analysis technology of micro-and micro-structural information in three-dimensional soil. However, with the development of multifunctional, high-precision and large-range X-ray CT, these problems are expected to be solved step by step.

The third is to establish a practical theoretical model, and solve all kinds of complex and difficult core problems in geotechnical mechanics and engineering of "three deep projects" to help improve the engineering design level. In different geotechnical engineering problems, the stress path experienced by soil is different, so it is difficult to accurately obtain the stress path and mechanical properties of undisturbed soil in the field by current geotechnical testing technology. Therefore, it is a research idea to establish a practical constitutive model by using appropriate methods for simulation and corresponding indoor experimental research.

Fourth, the four branches of macro-micro soil mechanics and modern soil mechanics and the cross-development of other disciplines. Macro-micro soil mechanics can not only cross theoretical soil mechanics, computational soil mechanics, experimental soil mechanics and applied soil mechanics in this discipline, but also cross other disciplines, such as rock mechanics and near-field dynamics in mechanics disciplines. This will not only contribute to the self-development of macro-micro soil mechanics, improve modern soil mechanics, but also promote the rapid development of other disciplines.

In a word, macro-micro soil mechanics has become one of the most dynamic research directions, and its accelerated development period is coming soon. To this end, we need the participation of many young scholars with solid foundation and prime of life, as well as the care and support of senior researchers who have been fighting in the front line of scientific research for a long time and have a deep understanding of difficult and key problems in geotechnical engineering.

　　China news agency, Beijing, February 9 (Reporter Ruan Yulin) The Ministry of Environmental Protection of China informed the media on the evening of the 9th that a systematic dusty weather process occurred in China, which affected Inner Mongolia, Gansu, Ningxia, Shaanxi, Shanxi, Hebei and other places, and the hourly concentration of inhalable particulate matter (PM10) rose sharply, with the hourly concentration of PM10 in Zhangye City, Gansu Province exceeding 3,600 micrograms per cubic meter.

　　Influenced by the gale weather, a systematic sandstorm weather process occurred from north to south in China from noon on February 8. The sand was mainly located in southern Mongolia, central and western Inner Mongolia, China and western Gansu. The sand and dust weather process first appeared in cities such as Xilingol, Jiayuguan and Jiuquan, and then the influence of sand and dust expanded from Inner Mongolia and Gansu to Ningxia, Shaanxi, Shanxi, Hebei and other provinces. Among them, at 20 o’clock on the 8th in Zhangye City, the hourly concentration of PM10 exceeded 3,600 micrograms per cubic meter, which is the highest concentration of PM10 so far.

　　The monitoring shows that the Beijing-Tianjin-Hebei region and its surrounding areas began to be affected by this dusty weather process in the early morning of February 9 due to the cold and high pressure in the south. On the morning of 9th, the concentration of PM10 increased rapidly in several cities in north-central Shanxi. Among them, the concentration of PM10 in Shuozhou exceeded 1000 micrograms per cubic meter at 8: 00 on the 9th, and the hourly air quality index (AQI) reached 500. Lvliang, Xinzhou, Shuozhou and other cities also experienced hourly AQI reaching 500. At 9: 00 on the 9th in Beijing, dust was transported from the west, and the air quality deteriorated slightly, and gradually improved in the afternoon.

　　The forecast shows that at present, the dust front has arrived in the central and southern areas of Beijing, Tianjin and Hebei, and is still moving eastward and southward, and will gradually affect southern Hebei, western Shandong and northern Henan, and the air quality of relevant cities will deteriorate by 1-2 levels on the basis of the original forecast.

At the group management meeting in April, the management of Country Garden put forward the working policy of "one floor, one guarantee and delivery" in view of the current main tasks. In addition, we should seize the opportunity and strive for more projects to enter the "white list".

On April 7, Country Garden issued an announcement to disclose the progress of its overseas debt restructuring and the appointment of legal counsel. After Country Garden announced on October 10, 2023 that it was seeking a comprehensive solution, it cooperated with creditors and main consultants and made positive progress in overseas debt restructuring. The company has set up a coordination committee representing bank creditors and a project team representing bondholders. At present, the two sides are discussing the information sharing mechanism and fee arrangement.

Country Garden is conducting feedback on due diligence issues, and referring to international best practice guidelines, including the Second Edition Statement of Principles on Global Experiences of Multi-creditors in Solving Debt Problems without Court Procedures and the Code for Handling Financial Difficulties of Hong Kong Enterprises.

Country Garden said that the main financial consultants are continuing to advance the preparation of the cash flow model. In addition, in order to provide a common information platform for creditors, the company has hired De Anhua to analyze the independent debt recovery rate of the group on the premise of being cautious to creditors, so as to help creditors make better rational judgments when examining the company’s operation in the future.

It continued that Country Garden plans to establish a regular communication mechanism with overseas creditors and update the restructuring process to overseas investors in a timely manner. The company reiterates that we are determined to promote a comprehensive solution that can ensure the long-term development of the Group, safeguard the rights and interests of all stakeholders and ensure fair treatment of all creditors.

Country Garden also said that the company has appointed Nianlida Law Firm as the main legal adviser for overseas debt restructuring. Nianlida Law Firm will work with the company and its main consultants to ensure a transparent and constructive dialogue between the company and overseas creditors.

At the end of February, Country Garden announced on the Hong Kong Stock Exchange that the company was informed of the liquidation petition filed by Ever Credit Limited to the High Court of the Hong Kong Special Administrative Region on February 27, 2024, concerning the unpaid term loan with a principal of about HK$ 1.6 billion between the petitioner (lender) and the company (borrower) and accrued interest. The company will strongly oppose the petition.

On March 28th, Country Garden announced that it would delay the publication of the 2023 performance report. The explanation given by the company for delaying the publication of financial reports is that the industry continues to fluctuate and the business environment faced by the company is becoming increasingly complex. It needs to collect more information to make appropriate accounting estimates and judgments. Affected by this, Country Garden shares have been suspended since April 2.

The Game Awards, a new activity sponsored by Sony, Microsoft, Nintendo and Villefort, replaced VGA and VGX. The Game Awards is also known as the Oscar in the game industry. It has been eight times since it was founded in 2014, and the outstanding works that have been born in these eight years have all been nominated or won prizes at TGA. Then let’s review the winners of the current eight annual game awards and the competitors nominated that year.

2014 (First Session): Longteng Century: Trial

Nomination:

Bayonetta 2

Dark Soul 2

Hearthstone

Middle-earth: Shadow Mordor

Longteng Century: Trial is the third work in the series, and its development studio Bioware continues its consistent style. Created an interesting RPG world. Of course, there are some obvious shortcomings, its content is a little lengthy, and there are a lot of fragmented exploration content. However, in general, the defects are not hidden, and the high scores given by the media also make its first TGA annual game truly deserved. The other nomination games also set off a wave in that year. However, the volume is still slightly insufficient, so it is not too controversial that Longteng Century: Trial won the first TGA annual game.

2015 (Second Session): Wizard 3: wild hunt

Nomination:

Blood source

Radiation 4

Made in Super Mario

Metal gear 5: Phantom Pain

"Wizard 3: wild hunt" is indeed the pinnacle of CDPR, with rich game content; Fascinating plot, and the cooperation between witchcraft and fencing; And the Kunte brand game as a small egg. There is no doubt that you can feel the intention of CDPR at that time, and finally it won the best game of TGA in 2015. However, this year’s nominated lineup is Starlight Glimmer, Fromsoft’ware’s PS exclusive masterpiece Blood Source: Curse, the fourth generation of Radiation series, Nintendo’s popular series "Made in Super Mario" and Kojima Show’s last work in Kelemei "metal gear 5: Phantom Pain"; In this lineup, deus ex’s "Wizard 3" is even more valuable.

2016 (Third Session): Watching the Pioneer

Nomination:

Doomsday 4

《Inside》

The Fall of Titan 2

Mysterious sea 4: the end of thieves

If you want to ask what is the hottest game in 2016, then I’m afraid nine out of ten people will tell you that you are a watch pioneer. When Blizzard officially launched the game, it became popular all over the network. On the basis of adding skills to the FPS game in Legion Fortress 2, Blizzard further refined and designed various heroes. And then it was a great success. At that time, the most powerful competition of the annual game of Watching Pioneer was "Mysterious Sea 4: The Thief’s End" from the naughty dog studio. I privately thought that the game was the pinnacle of naughty dogs. At that time, both the exquisite picture and the design of checkpoint battles tended to be a perfect posture. Of course, in the end, Watch Pioneer still won the championship successfully. Compared with Mysterious Sea 4, Watch Pioneer’s phenomenal performance won it the annual game of that year.

2017 (4th): the legend of zelda: The Breath of the Wilderness.

Super Mario: Odyssey

Playerunknown’s Battlegrounds

Unusual Records of Goddess 5

Horizon: at dawn

That year’s TGA was a fairy fight, but the legend of zelda: The Breath of the Wilderness still stood out successfully. The breath of the wilderness handed in a perfect answer sheet in the production of open world games, and with the game mechanism, countless ways of playing can be played; Different designs of temples. The biggest winner in that year was Nintendo, which once again proved to the world that as long as the game is fun, it has nothing to do with the excellent picture quality. Even in the poor function of NS, you can appreciate the charm of this annual game.

2018 (Fifth Session): god of war 4

Nomination:

Marvel Comics Spider-Man

Fistful of dollars 2

Assassin’s Creed: Odyssey

Monster Hunter: The World

Blue

Santa Monica shows people what it means to be poor, and god of war 4 has changed a series of consistent combat modes. In the use of a new combat mode, Santa Monica still makes it very solid; Under the background of brand-new stories and myths, god of war 4 has succeeded in reinventing a world. What is more regrettable that year is fistful of dollars 2 from R star, which has a flavor from the western United States in picture performance, story narration and fighting mechanism. Even after many years, many players are still playing this game.

2019 (Sixth Session): "Only Wolf: The Shadow Dies Twice"

Nomination:

Control

Death stranded

Nintendo Star Wars

Resident Evil 2: Remastered Edition

Outer world

Hidetaka Miyazaki, who was full of malice, finally won his victory that year, and all the games owned by FromSoft were full of soul. And only the wolf uses the righteous hand and all kinds of moves to fight against Boss, and then it is natural to win the annual game award on the basis of the excellent fighting of the soul series.

2020 (Seventh): The Last Survivor 2

Nomination:

"gather! Animal Forest Friends Association

Doom Warrior: Eternity

Final fantasy 7: remastered version

Soul of Tsushima Island

Hades

Last year’s best game of the year was awarded to The Last Survivor 2, which was also controversial at that time. On the one hand, The Last Survivor 2 was the top one at that time in terms of play and picture quality, on the other hand, As an RPG, The Last Survivor 2 caused some players’ dissatisfaction in plot. Therefore, many players think that the annual game should be awarded to "Soul of Tsushima Island", and the Soul of Tsushima Island is a masterpiece with a solid gameplay and a distinctive artistic style.

2021 (Eighth Session): "Walking for Two"

Nomination:

Death cycle

Mitterrand: Fear of Survival

Brain pilot 2

Ricky and Tinker Bell: Time Jump

Resident Evil 8: Village

This year is recognized as a small game year, and there are few loud masterpieces released this year. As far as the quality of "Two in a Row" itself is concerned, it has successfully won the first prize. The very interesting play mechanism and excellent level design make this small game look very delicate.

　　Cheng Lei, correspondent of China Meteorological News, reported. At 17: 15 on October 8, Dandong City, Liaoning Province issued the first blue warning signal of frost in autumn. It is expected that there will be frost or frost in Fengcheng City and Kuandian County in the early morning of the 9 th. The latest data shows that the temperature in many towns and villages has dropped to freezing point, and strong cooling has a negative impact on agricultural autumn harvest.

　　In view of this large-scale severe cooling weather, the municipal meteorological department attached great importance to it, strengthened duty watch, encrypted observation by business personnel, strengthened weather consultation between upstream and downstream, and timely released forecast and warning and the latest weather situation to municipal leaders, relevant units and the public through early warning platforms, meteorological information display screens, Weibo and radio stations, and put forward reasonable suggestions on the harvesting of rice, open-field melon and fruit crops, autumn vegetables, flowers, flue-cured tobacco and fruit trees, so as to minimize the harm caused by frost.

　　There are many pictures of children in the live screen shots of bars visited by reporters of Beiqing Daily.

　　Have you ever thought that your every move has been broadcast live on the internet through surveillance cameras from the moment you step into a restaurant or gym? Yesterday, a post-90s girl who claimed to be Chen Feifei published an article, publicly questioning that the "water drop live broadcast" on the 360 platform broadcasts public privacy in public places. After visiting the investigation, the Beijing Youth Daily reporter found that there were indeed cases where the merchants did not express the consumers so as to broadcast live. In response to this question, 360 Company responded that whether to turn on the live broadcast function depends entirely on the decision of the purchased merchants.

　　event

　　After 90, netizens issued a document questioning the privacy of 360 platform live broadcast.

　　On December 11th, Chen Feifei, a post-90s girl, published an article "A post-90s girl to Zhou Hongyi: Stop staring at us" on the WeChat public platform, openly questioning that "live water drop" violated public privacy. In just one day, the article was read more than 100,000 times.

　　"I also saw an announcement on the live broadcast of water droplets a few days ago: kindergartens can apply for 360 cameras for free. Under the protection of 360, I feel the warmth of my uncle again. I am a product experience video myself. Out of professional curiosity, my colleagues and I found that the content of the live broadcast of water droplets is really dazzling: enchanting dancing posture, children playing in amusement parks, close-ups of entering passwords, and cozy donkeys in farms … …”

　　The reporter of Beiqing Daily saw in the video shot by Chen Feifei that the average daily audience of the live broadcast platform reached more than 7 million. Click on the software of 360 camera, one of which is called live water drop, on which you can see all kinds of monitoring pictures. There are 657 live broadcasts in Beijing alone. It is mentioned in the article that the live broadcast platform requires users to post live broadcast notices, and the Announcement on Setting Live Broadcast Prompts by Merchants requires that the merchants broadcasting on the platform should set up obvious live broadcast prompts in the live broadcast area to inform customers, and the prompt stickers should be clearly exposed on the screen, or the words like "our shop has informed customers of live broadcast" should be noted in the introduction of the live broadcast platform, but the investigators found that "the merchants were disobedient and rarely posted".

　　Subsequently, the investigator asked two customers about this matter how they felt about being televised live. "Would you like to be broadcast live? How do you feel about being broadcast live 24 hours a day? " After getting this rhetorical question, two customers left the hotel.

　　site

　　There is no live broadcast in the store, and customers are generally unaware of it.

　　Yesterday evening, the reporter of Beiqing Daily came to a bar near the East Third Ring Road in Chaoyang District. On that day, this bar has been broadcast live on the water drop platform. When you walk into the bar, you can see the camera for monitoring in the corner of the ceiling above the bar. The camera is turned on, and it is exactly the same as the corresponding camera position in the live picture. "This camera is connected to the boss’s mobile phone. He can monitor the situation in the store at any time, and the camera can transmit voice, and the boss will talk to us directly through the camera." The bar staff said, but they didn’t know whether the monitoring screen was broadcast live.

　　At the same time, the reporter of Beiqing Daily did not find any notices posted in the store about monitoring the live broadcast, and the customers who entered the store did not know that they were being broadcast live. Among the merchants who opened the live broadcast visited by the reporter of Beiqing Daily, they also did not see any publicity about the live broadcast.

　　Yesterday evening, there were only more than 300 live broadcasts in Beijing on the water drop platform, which was reduced by half compared with more than 600 mentioned by Chen Feifei in the article the day before.

　　Yesterday, the reporter of Beiqing Daily also interviewed several consumers on this matter. Mr. Wang, the customer, said that he could not accept it after learning that his picture under the surveillance camera was placed on the live broadcast platform. "I can’t accept even posting notices. After all, it involves personal privacy. No one likes to be peeked at in a restaurant, and you are uncomfortable watching you at the next table, let alone being broadcast live on the Internet. Unless I voluntarily agree, even if the business is publicized, it does not mean that I must accept it. " Ms. Ding said that it is acceptable for certain minority groups, such as children in kindergartens and schools. "But in public, it is definitely not possible to broadcast live to unspecified people."

　　Whether to turn on the live broadcast function depends on the merchant.

　　Yesterday, 360 smart cameras team made a public response to this matter. 360 said that the live broadcast of water droplets is one of the important functions of 360 smart cameras, and it is turned off by default. Whether to turn on the live broadcast function depends entirely on the decision of the purchased merchant. Merchants who buy 360 smart cameras must register their real names if they want to start using the water drop live broadcast mode, and the content they shoot must have no personal privacy of themselves or others, and ensure that the content they shoot is healthy and does not violate the law. Some merchants choose live broadcast because consumers can intuitively feel the service of merchants by browsing the live broadcast pictures of merchants through mobile phones.

　　Some merchants did not fulfill their obligation to inform consumers when they broadcast live water drops. 360 smart cameras’s user agreement requires merchants to set up obvious prompts in the live broadcast area, such as posting prompt stickers to inform customers. Once it is found that the merchant has not set a clear prompt, the water drop live broadcast will have the right to cut off its live broadcast signal.

　　At the same time, the water drop live broadcast platform has established a strict content review mechanism, and a team of nearly 100 auditors has been established to review and check the live content 24 hours a day. Except for the special edition of kindergarten and the version of "Bright Kitchen", 360 smart cameras has never given it to any other merchants, and has never encouraged merchants to broadcast the monitoring screen live.

●　New forces of building cars

　　Compared with July, everyone delivered ten thousand pieces of happiness and peace in succession, but this month, it showed a state of differentiation. Nezha rose to 16,000+,and the family in the world welcomed it, but the ideal fell less than 5,000.

★ AITO automobile

　　Brother Wen Jie’s performance in August was remarkable. Its delivery in August reached 10,045 vehicles, and it proudly advanced into the camp of breaking 10,000 vehicles, ranking fourth among the new forces. It seems that the cow that Yu Chengdong blew is coming true soon?

　　On September 6th, the first pure electric SUV—— of AITO brand, Wenjie M5 EV, was officially launched. Two new models were launched, and the price was 288.6-319.8 million yuan, which was just between the low-end and high-end versions of the extended-range M5. Its appearance perfects the product line of AITO automobile, giving consumers more power choices, and with the blessing of "Huawei BUFF", I believe that the brothers in the world can take a fancy to it.

★ LI

　　Unlike AITO’s celebration of entering the Breaking Ten Thousand Club, it is ideal to deliver a total of 4,571 new cars in August. It’s a bit embarrassing in the new power. However, this should be the "pain" in LI’s progress. At present, it is at the end of Li ONE’s life, and the production capacity of the ideal L9 has not completely climbed, so it is understandable that there is a short-term "green and yellow" state.

　　At present, it is ideal to hold a large number of orders for L9. In November this year, the next new car L8 will also be released and delivered, as well as factories in Changzhou Phase II, Chongqing and Beijing. We believe that the ideal sales volume will return to a reasonable level.

■ Edit comments

　　The sales comments in August have come to an end here. At present, there are still many brands that have not announced their sales, and we are also waiting for good news. After the summer heat passed, it immediately ushered in the classic "Golden September and Silver 10" in the automobile industry, which officially rushed to a good period of sales. Major car companies have also prepared a lot of heavy models in the third and fourth quarters. How will their arrival change the sales of major car companies? Please continue to pay attention to car home’s sales reviews, and we will be there next month. (Text/car home Xing Yueyang)
