On the social networks where Zhihu, Douban and other young artists gather, there has never been a lack of such topics as "XX absolutely beautiful unpopular songs" and "Recommend some popular music that is nice but not popular". There is no distinction between the public and the minority in the genre of music. The so-called minority or unpopular music is mostly defined according to the amount of play or the audience.

　 　 　 　　Van adib, CEO of eCast, discovered the famous "98 Rule" in his research on digital music, that is, the audience has unlimited demand for 98% of non-popular music, and the market for non-popular music collections is enormous and boundless.

　 　 　 　　On the one hand, there is a strong user demand, and on the other hand, there is a huge market prospect. How to recommend these 98% unpopular songs to the audience has been tried by music service providers all over the world, as has the domestic online music platform, and Netease Cloud Music, which stands out by virtue of the unique positioning of the music community, is one of the best. Compared with the average utilization rate of music libraries below 20% in the industry, Netease Cloud Music has reached 80% of "going against the sky". In addition to the ingenuity of products, Netease Cloud Music has mainly done two things right.

1. Reconstruct the music recommendation method.

　 　 　 　　Netease Cloud Music was launched in April 2013. At that time, most of the music software on the market was "music library+player", which played the role of listening to songs. It is not difficult to understand the phenomenon mentioned at the beginning of this article. Users can’t find their favorite music in the music player, and interest-oriented online communities have become a natural medium for discovering and sharing music.

　 　 　 　　The appearance of Netease Cloud Music has changed the traditional music recommendation method, mainly in two aspects, one is song list, and the other is personalized recommendation.

　 　 　 　　Let’s start with the song list, which is similar to the song sharing article on Douban, but it is transferred from a third-party social platform to a music APP, which is also in line with the positioning of Netease Cloud Music Music Community. The song list has realized two direct functions. In the past, the chaotic song collection was solved after joining the song list. In the past, users had a strong dependence on various lists to find songs, which actually accelerated the difference between popular and non-popular. Songs appearing on the list will be heard by more people, while music outside the list may become a long tail. On Netease Cloud Music, song list has replaced the list as a popular listening behavior.

　 　 　 　　Up to now, the number of high-quality song lists created by users on Netease Cloud Music has exceeded 200 million, with an average of 420,000 song lists created every day. This figure far exceeds the posts recommended by music on social platforms. Through the song list, users can find the music they listen to at work, the lullaby they listen to when they are insomnia, the unpopular music they can’t miss, and even the background music of PPT. Not only has it solved the pain points of users, but for Netease Cloud Music itself, the song list has become a "trump card" to maintain the stickiness of users.

　 　 　 　　Personalized recommendation is another initiative to solve the problem that users find good music, so Netease Cloud Music is also called a music player that "knows you better than your mother".

　 　 　 　　The great god in Zhihu has a professional explanation for the recommendation mechanism of Netease Cloud Music, which is mainly divided into two parts in algorithm, the recommendation of similar people and the recommendation of similar songs. As the name implies, similar songs mainly Tag songs in the music library, and push music with similar tags or the same tags according to users’ listening habits. The recommendation of similar people refers to modeling according to users’ listening habits, and screening out people with similar tastes. For example, A and B belong to the same kind of people, and the songs that A likes are probably the ones that B is willing to listen to.

　 　 　 　　Through song list and personalized recommendation, Netease Cloud Music has established a recommendation mechanism of "algorithm+labor +UGC", which not only satisfies the interest of users, but also ensures the quality of products.

　 　 　 　　There is a "story from Netease cloud music to the real world" circulating on the Internet. GalenCrew is a relatively small singer in both China and the United States, but his single Sleepyhead has tens of thousands of comments on Netease cloud music. Finally, Galen began to tour in China, and the venue was full.

2. Break the barriers of music sharing

　 　 　 　　Music sharing in the traditional sense is mostly word of mouth or shared on social networking platforms. After all, it is still the active sharing of users. Especially for minority music, many listeners have a mentality of "like it but don’t want it to be popular", and it is difficult for traditional sharing methods to break this boundary.

　 　 　 　　In essence, the song list and personalized recommendation on Netease Cloud Music also belong to the category of sharing. The song list was created spontaneously by users and found and collected by "music friends" with similar interests, among which there were many song lists with hundreds of thousands or even millions of listeners. According to the personalized recommendation of similar people, the sharing process was imperceptibly completed.

　 　 　 　　However, what Netease Cloud Music enjoys in sharing is the positioning and comment mechanism of the music community. The former meets the needs of users to share good music, so that good music can be shared with like-minded people, which is in line with the behavior habits of minority music lovers. Many listeners of minority music have their own circles. They recognize each other’s identity and values and enjoy the sense of security that this group gives them. And this kind of people in the hope of independence and eager to communicate, we strive to expand the small circle, while trying to control the small circle in the illusion of independence. Compared with popular social channels, Netease Cloud Music’s vertical socialization is just what it wants.

　 　 　 　　But music itself is also a commodity, and it is bound to be tagged. When we listen to songs, the background data of online music is constantly tagging us. The so-called niche only exists in data algorithms. This kind of label is a good thing for the promotion of minority music. Compared with the promotion for individuals, the label-oriented group has more advantages in both accuracy and cost. How to recommend minority music to more people’s ears according to this feature? Netease Cloud Music chose the comment mechanism.

　 　 　 　　The Indonesian song "Bila" has 25,000 comments on Netease Cloud Music, and the most praised comments are 46,000.

　 　 　 　　Yes, it’s a comment, not a grade. According to the rules of scoring, users score their favorite or disliked music, and then find out similar user groups on the difference of scoring. However, if there is a score, there will be a brush score, which will lead to irrational behavior of the user group and even cause the loss of users in a large area. In addition, letting users rate songs that have been listened to for a few minutes increases the cognitive cost of users, and it is also a kind of harm to music itself. Music has no advantages or disadvantages, only likes and dislikes.

　 　 　 　　Netease Cloud Music’s comment mechanism has achieved results. At present, it has generated 400 million comments, and users have generated 640,000 music comments every day. More than 50% of users have developed the habit of commenting while listening to songs. Compared with the digital rating, this kind of comment entrusts users with more emotional factors, such as excellent comments will be praised at the top. Moreover, music criticism itself is a kind of sharing, and it is a way for users to express their love for works. Even some relatively unpopular music still gets tens of thousands of comments.

　 　 　 　　Almost all fields are looking for explosions, such as e-commerce, IP, and even music. But distributing pop music to more people is an ability to bring more fans to minority music or unpopular songs. This is feelings.

"Access to DeepSeek" was the hottest word in the car circle in the past few months, but it was the hottest word in the car circle. Now that the noise has subsided and returned to reason, it is time to seriously discuss how AI will reshape the car.

Let’s put a conclusion here first:AI may be the key point of qualitative change of automobile intelligence.

The reason lies in the evolution direction of several core plates of automobile intelligence, all pointing to the ability demand of AI big model: intelligent cockpit should be able to provide more personalized customization or active service; The "end-to-end" required by intelligent driving requires faster and more flexible understanding and decision-making ability; As the bottom support, automotive electronic and electrical architecture is turning to domain centralization and central computing in an all-round way, which requires centralized and flexible scheduling of computing power.

The characteristics of AI big model are also the key solution: the universal base provides a computing base combining end and cloud, and the big model is good at coordinating multi-party information and making quick decisions, especially in the face of common travel scenarios, which can form solutions and give direction suggestions and references in the face of special situations such as corner case.

This has made clear the key to the next generation competition of automobile intelligence, and it may even be the biggest change that automobile, as a tool for human travel, faces in a century of development:AI will become the infrastructure of the next generation of smart cars.

However, it will still take time for AI to reshape the car: the construction of infrastructure is by no means a day’s work. If there is no fundamental integration and transformation of the underlying technology, just like this wave of car companies focusing on marketing, it is neither decent nor honest to make a simple dialogue interface between people and cars, or even to fool directly with a web browser.

Going around, the serious evolution from the beginning of infrastructure depends on the determination and thinking of the giants.

On March 3rd, Geely held a conference on AI intelligent technology, which revitalized the seemingly irrelevant "idle chess" in various fields, demonstrating the first in-depth thinking result of AI as a smart car infrastructure.

Dimension reduction from the beginning of infrastructure

Geely may be the first car company in the automobile circle to seriously discuss the construction of AI infrastructure.

Compared with the "grand strategy" that friends like to announce in the AI field, Geely spent nearly one-third of the conference space, and invited Yin Qi, an AI industry expert and chairman of Qianli Technology, to share the basic judgment on the development of AI big model from the perspective of automobile industry as a member of Geely Technology Ecology, based on objective technical facts.

There are a lot of dry goods. Let’s first look at the final answer of the evolution of AI+ cars given by Geely.

Geely called it "the birth of supernatural human-computer interaction". The logic behind it is that, unlike PC as the core carrier of digitalization and mobile phone as the ultimate entrance to the Internet, AI needs more energy consumption and more access to real information, so cars naturally have the advantage of becoming a "mobile terminal" in the AI ? ? era. The most direct change brought about by AI’s natural "multimodal" interaction and reasoning ability is to connect various services in series across user travel scenarios.

Imagine that in a go on road trip, vehicles can take over the whole driving control according to the accumulation of your usual daily habits, and intelligently help you book the destination food in advance, intelligently recommend different services to couples, family, friends and elders during the trip, and even link with your mobile phone after the trip to intelligently generate travel notes, which can be shared with one click … ..

The so-called "supernatural human-computer interaction" is not a subversion of starting a new stove, but a one-way instruction of traditional people to equipment. It is also a two-way suggestion and feedback between people and equipment, and finally people can communicate with each other and even understand your feelings better.

With a clear goal, starting with the end, we can find the greatest common denominator of infrastructure.Geely’s infrastructure advantages in AI big model can be understood from two key words: computing power+general model.

Here, a few figures can be used to visually show Geely’s achievements: Geely’s "Smart Car Computing Alliance" is based on Star Smart Computing Center 2.0, and its comprehensive computing power has increased to 23.5 EFLOPS. According to "China Computing Network Market Operation Status Survey and Investment Strategy Forecast Report (2023-2030)",By the end of 2023, the scale of AI in China will reach 200 EFLOPS, and Geely’s AI computing power layout is enough to rival nearly 1/10 of the country.

Sufficient computing power corresponds to Geely’s higher goal of building a universal base model.

What is common in the industry is the vertical intelligent driving model, which is short, flat and quick, and easy to produce results. You can understand the difference between the two models like this:Vertical intelligent driving model is a kind of intelligent driving technical scheme that integrates all kinds of road driving scenes, and emphasizes the familiar ones such as laser radar and visual perception, and its relative sources are also limited.

But it is different from the information input and feedback of people’s real driving. People are natural "multi-modal input". You will form a trend judgment according to the change of traffic flow ahead, the command of pedestrians or traffic police, and even the seemingly unrelated scene changes on the road ahead, and make a subconscious reaction and judge the next road conditions and operations.

The universal base model is born for this multi-modal nature, but the exponential explosion of its data volume means that it needs stronger computational support.

An intuitive data comparison is that the specifications of the intelligent driving model widely used in the automobile industry are about 10 million video clips, and a large number of repeated scenes will be mixed in the middle, while the data volume of the universal base model can easily reach 1 billion, even for similar scenes, it will identify the internal trend changes more carefully. Only in the recognition degree of the general obstacle, compared with the industry model, the general model is the gap between "100,000 categories" and "50 categories", and even can identify new obstacles through reasoning, forming the ability of independent learning and decision-making.

To put it bluntly, the universal base model is essentially observed in a mode closer to the real human thinking, and the result is closer to the real human road judgment and driving mode, and truly realizes the anthropomorphic "fully automatic driving" above L3.

On this basis, in order to better understand the real world, Geely and Eco-Partners have created a model matrix that integrates language model, multimodal model and pan-world model. Among them, the language model represented by DeepSeek is aimed at the smooth interaction between human and computer, and the rapid understanding of the world abstract information into words by intelligent driving.

The multi-modal model is represented by Geely’s AI ecological partner Step Star, which can understand and generate images, music and videos. In the end, the foundation of the future industry includes VLA and a world model that can understand the objective reality. Geely has simultaneously laid out the AI Drive model at this level, laying a good foundation for intelligent driving above L3.

According to the computing power demand of the common large model in the industry, the universal base model needs at least tens of thousands of cards for a single training, so this is a "dimension reduction blow" that a "head player" like Geely can achieve. Looking back at Geely’s "Smart Geely 2025" plan put forward at the Longwan conference in 2021, it was now curious and questioned by many people at that time. Geely’s heavy investment and extensive layout in the digital field now have a new answer.

The competition for "AI+ cars" has just begun.

Why is it called a thousand miles?

In the matter of AI reshaping the car, Geely played its own stubbornness as building a car:Starting from the bottom structure, we should pursue the accumulation of wealth and thin hair in the final landing. Only in this way can we meet the goal of "high value" and achieve the blow of dimension reduction.

At the press conference, as the first landing of the AI strategy, Geely released a self-developed "thousands of miles" intelligent driving system, and took the lead in carrying it on two cars: the 2025 modified version of Geely Yinhe E8 and Geely Yinhe Xingyao 8EM.

As a unified intelligent travel solution formed by Geely through AI technologies such as end-to-end, VLM and world model, Qianli Vast is divided into five different levels, namely H1, H3, H5, H7 and H9, with a minimum standard computing power of over 100TOPS.Highest H9 is the industry’s first L3 intelligent driving solution with mass production landing capability, which will be carried on all Geely models.

The most intuitive benefit brought by the vastness of thousands of miles is that users no longer have to choose between the inconsistent experience of intelligent driving and the complicated packaging words of different manufacturers. At the turning point when industrial technology enters the popularization period from the rising period, it is obviously much more important to let more people use it with low threshold than the dazzling skills and packaging of high-end technology.

Geely named this intelligent driving system "Qianli", and the strength behind it is the industry-leading general model and computing power. This is one aspect of technology, and the vastness of the other side emphasizes that this intelligent driving system is not only rich enough to support intelligent driving in various scenarios, but also stable and reliable. As the "safest intelligent driving system", Qianli Vast can be integrated with Geely’s technical standards in the field of car building.

At the press conference, Geely showed a typical scene: the AEB of 120km/h stopped automatically. As one of the most risky dangerous driving scenarios that most users may encounter, compared with many brands who still use this ability as a gimmick for high-level intelligent driving, Geely can directly declare the vast expanse of thousands of miles as a standard, and even avoid the risks in the same lane, and can also avoid the risk scenarios that appear continuously in two lanes.

Qianli Vast integrates the self-research power of Geely’s ecology, which is essentially based on the brand-new anchoring of the industry layout for many years, the VLM model of vision and integration of language, and the universal model base based on the understanding of the real world, and on this basis, it promotes the first mass production of L3.It indicates that China enterprises, represented by Geely, are setting up a real moat in the field of intelligence, especially in terms of technology and experience standards integrated with the whole vehicle, which means that they are ready to promote the maturity of laws and regulations and promote them globally.

This is the competition for upgrading the dimension after laying the foundation first. Compared with most enterprises in the industry, which are still using smart driving to create profit space and avoid responsibility, Geely has made the vast expanse of thousands of miles into the best and most time-tested value in the century-old automobile industry: standard.

AI defines the first player of a car.

Geely’s years of development actually follows similar thinking:Under the grand strategy, the grey line of grass snake will be continuously laid out, and then it will be applied first when the industry changes its qualitative point, so as to realize the great leap and the establishment of moat.

From the acquisition of Volvo, the layout of smart Geely 2025, the layout of vast architecture, and the release of Ningbo Declaration and Taizhou Declaration, Geely AI technology conference marks the first time that Geely has completed the first transformation to "AI defines cars".

The industrial leap of any technology must be the first move of the explorer and the follow-up with the industrial giants, so as to jointly promote the application for thousands of households. The entry of an industrial head enterprise like Geely marks the seeds of innovative technology brought by DeepSeek or other AI ecological partners, with the soil to land.

Similarly, they all need to go through the process of long-term exploration in core technologies and bear huge sunk costs and risks; What a giant like Geely has to do is to discard the false from the true as soon as possible and complete the popularization and application of engineering. In this process, advanced technology has to find true value for users and popularize more scenarios, which is bound to be a long-term process.

But this may also be the "high-value" experience that users can reach at their fingertips as soon as possible: once AI builds a car, it will not be far from the mature products such as "It just works" once it enters the unknown technical engineering.

In recent years, more and more urbanites choose to keep pets as companions. After a busy day’s work, it is undoubtedly a "charging moment" for pet owners to be greeted by pets at home, and the fatigue is instantly forgotten.

However, there are also many people who also love pets, but they dare not take the step of raising pets, not because of the cost and energy consumption brought by breeding, but because they are afraid of the sadness after losing their "family".

After all, compared with the life span of people, the life span of pets is mostly short. So, what kind of pet can bring relatively long-term companionship?

Text | Big Meng Ni | Roxie Diagram | Four Elephants Design Department

01

What kind of pet do you want to have longer company?

They are also "good friends of human beings", and the life span of different pet breeds is very different.

Hamsters with an average life span of only two or three years have turtles that can live for more than 30 years … … and most pets have an average life span of less than 15 years.

For example, the average life span of our most familiar pet dogs is about 10~13 years; The average life span of pet cats is slightly longer, which is only 12~15 years.

But this is only the average value. In fact, even if it is the same species, the life expectancy of different varieties is not consistent. Take pet dogs as an example, the general rule is that the bigger the body, the shorter the life span. The average life span of large dogs is about 9 years, while that of small dogs can reach 12 years.

It can be said that the companionship of more than ten years is the cornerstone for pets to establish close feelings with their owners.

02

Do pets and owners grow up together?

In many families, pets grow up synchronously with children, and the process of children growing up from babbling toddlers is also the process of pets entering old age from childhood. From this perspective, a pet’s life is also an important part of family memories.

Because the absolute length of pets’ life span is not as long as that of human beings, their growth rate will naturally not be completely synchronized with human beings. Taking pet dogs as an example, there has always been a saying that "a dog born for one year is worth seven years to human beings". Is this really the case?

In fact, the age conversion between dogs and humans is not linear, but variable.

Pet dogs grow very fast when they are young, and they can develop into a state of about 20 years old in half a year. But after rapid adulthood, the pace of maturity of dogs will gradually slow down. When the dog lives to be seven or eight years old, the aging rate will further slow down. At that time, when the dog is one year old, it is probably only equal to one or two years of life.

In many families with pets and babies, there will be a warm scene of pets looking after babies. In the eyes of human parents, it may be that children of the same age are playing with them, but in the inner world of dogs, it may be that mature "middle-aged dogs" are fulfilling their responsibilities and helping young people at home to take care of their cubs.

03

The average life expectancy of people is rising, but pets are declining.

Pets, which occupy an important position in the family, have also buried emotional hidden dangers for their owners-once their lives come to an end, they will bring a huge psychological blow.

It is precisely because of the rising status of pets in the family that human capital investment in pet medical care and even pet funeral has reached an unprecedented height. Many people spend a lot of money to treat their pets, and some people spend a lot of money to do things for their pets, just to let the hairy children go smoothly.

In the last decade, pet medical and pet funeral industries have ushered in a spurt of development. In 2023 alone, 1,920 pet funeral-related companies were established in China, while the total number of related companies established in the decade from 2003 to 2012 was only 64.

Although the time and cost that pet owners are willing to invest have soared, unfortunately, unlike the rising trend of human life expectancy, in less than 50 years (1970-2016), the average life expectancy of pet dogs has been shortened by 35%, from 17 to 11 years.

Why on earth is this?

In 2014, The Kennel Club, a British kennel club, investigated the causes of death of 5,700 pet dogs. The data shows that cancer is the biggest killer affecting its life span, accounting for nearly a quarter of the total, even exceeding the death of aging.

Among the dogs who died of cancer, the causes with the highest proportion were bone tumor (3.99%), lymphatic tumor (3.18%) and brain tumor (2.81%). The biggest killer that threatens human health also takes the lives of pets.

Ten years ago, The Kennel Club did the same research. The proportion of dogs that died of natural aging in that year was 17.8%, but now it is only 13.8%, that is to say, the number of pet dogs that died of diseases or accidents increased by 4% in ten years.

What is frightening is that the shortened life span of pets may be related to the popular lifestyle. According to the speeches of relevant insiders, the following three possibilities can be summarized:

First of all, genetic inheritance, artificial breeding of purebred dogs with similar blood vessels, easy to lose genetic diversity, greatly improving the probability of congenital genetic diseases; Secondly, pet dry food has changed the original diet structure, which is difficult to meet the demand of nutritional diversity, and long-term single nutrition source will affect its resistance; In addition, modern pets are often trapped in high-rise houses, and daily dog walking activities can not fully meet their activity needs, especially for large dogs.

The process of raising pets is not only that pets accompany people through a journey, but also that humans spend their lives with pets. Under the restriction of natural conditions, no matter what efforts are made, this is also a banquet that must end, but the time of sincere treatment will not live up to it. In addition to the investment of time, money and love, it is necessary to adopt scientific parenting methods to make this period of time longer and longer.

At present, the epidemic situation in COVID-19 has entered a new stage, and the focus of prevention and control policies has shifted to protecting health and preventing severe diseases.

How will Yunnan follow up? How to ensure the treatment of critically ill patients with infection in Covid-19? How to prevent and control epidemic situation in rural areas? The reporter interviewed the working groups of the leading group headquarters of the provincial party Committee and the provincial government to deal with the epidemic situation (hereinafter referred to as the headquarters).

"Yunnan has made comprehensive arrangements and detailed key tasks in epidemic prevention and control, and promoted the transition from anti-infection to’ health protection and severe disease prevention’." Yang Yang, deputy governor and director of the headquarters office, said that the provincial party committee and government have fully implemented the spirit of the important speech and instructions of the Supreme Leader General Secretary on epidemic prevention and control, and resolutely put "protecting health and preventing severe diseases" in a prominent position in epidemic prevention and control. Wang Ning, secretary of the provincial party committee, and Wang Yubo, governor of the province, made careful arrangements and conducted the whole process, and conducted special research once every two days to study and solve major problems such as 120 first aid, drug supply, ICU beds, key population management, rural rescue preparation, and led a team to conduct field research in medical institutions, which laid the foundation and created conditions for a stable and orderly peak in the province.

The provincial headquarters judges the epidemic situation every day, refines the tasks and measures, and does all the work in detail. At present, the province has reached a peak of stability, the number of positive severe cases has been decreasing day by day, normal medical services have been gradually restored, and the epidemic prevention and control has been smoothly and orderly.

Expansion fever clinic

Effectively cope with the peak of medical treatment

On January 14th, the reporter went to the fever clinic of the First Affiliated Hospital of Kunming Medical University, and the nurses were on duty. Compared with a week ago, the number of patients decreased significantly.

24-hour fever clinic, online and online fever clinic, and triage of emergency patients to specialist should not exceed 6 hours … Recently, the First Affiliated Hospital of Kunming Medical University has taken many measures to expand the capacity and increase the number of patients with fever, so as to ensure the smooth medical channels for patients with fever.

"In order to meet the medical needs of the masses to the greatest extent and fully ensure the smooth channels for fever treatment, the headquarters office requires medical institutions in the province to set up fever clinics (consultation rooms) to announce to the public to ensure that fever clinics are open 24 hours a day, and they are not allowed to close or stop the clinic without authorization." According to the relevant person in charge of the medical treatment team of the headquarters, in early December 2022, hospitals above the second level and township health centers (community health service institutions) in the province all set up fever clinics, and adopted measures such as expanding fever clinics, increasing the strength of medical staff, and rationally diverting medical staff to effectively alleviate the pressure of fever clinics. Conditional secondary and tertiary hospitals set up children’s areas to quickly triage and treat patients with common fever, adopt the combination of online and offline, improve the graded diagnosis and treatment service network of patients in COVID-19, open a green channel for transshipment, and arrange timely treatment in corresponding specialties for those who need specialist diagnosis and treatment or hospitalization.

At the same time, patients with medical needs can go to the nearest community health service institutions for treatment. Patients with serious illness and beyond the ability of primary diagnosis and treatment can go to the second-and third-level hospitals in their jurisdiction or be referred to designated hospitals according to their illness. In addition, the second-and third-tier hospitals in the province have opened online fever clinics, which provide citizens with relevant services such as consultation, prescription, drug purchase and medication guidance 24 hours a day, which can conveniently and efficiently allocate medical resources across regions and improve the efficiency of using high-quality medical resources.

As of January 14, 560 medical institutions above the second level in the province have set up fever clinics, and 1481 primary medical institutions have set up fever clinics. The peak number of consultations in the province’s fever clinics exceeded 150,000, and it has steadily dropped to more than 20,000. The relevant person in charge of the medical treatment team of the headquarters said that the peak of this round of epidemic infection in our province has passed.

Optimize the allocation of medical resources

Fully guarantee the treatment of critically ill patients.

After a week of high fever, cough, fatigue and muscle aches, Li Zhi, 85, was admitted to the intensive care unit of the Department of Respiratory and Critical Care Medicine of the First People’s Hospital of Yunnan Province. After diagnosis, Li Zhishuang’s lung has diffuse ground glass shadow, which belongs to critically ill patients with infection in Covid-19. Coupled with basic diseases such as hypertension and gout, his condition deteriorates rapidly. Through targeted treatment such as high-flow ventilator, his condition has been improving.

Since the establishment of a three-level response echelon in the First Provincial Hospital, each department has set up an infection treatment ward in COVID-19. The departments of respiratory and critical care medicine, infectious diseases and liver diseases are responsible for the guidance of the hospital’s departments on the treatment of Covid-19 infected patients and ensuring the resources for the treatment of critically ill patients.

In the past few days, all parts of our province have strengthened the preparation of medical treatment resources, rapidly expanded the number of critically ill beds, enriched and expanded the treatment team, set up an emergency medical support team, optimized the referral process mechanism, and medical staff at all levels raced against time to save lives and played a set of "combination boxing" to treat critically ill patients:

—— 281 general hospitals above the second level in the province set up intensive care departments according to the standards, strengthened the preparation of intensive care resources, and added intensive care equipment such as ventilators.

—— Strengthen the setting of ICU beds in general hospitals above Grade II, speed up the expansion and transformation of ICU beds in other specialties, co-ordinate the bed resources in internal medicine, surgery and other wards of the hospital, and reserve beds for intensive care step by step.

—— Organize internal, external, pediatric and emergency specialists to carry out intensive professional emergency training in comprehensive ICU, and effectively expand the intensive care team.

—— Breaking the routine, leading by doctors specializing in severe and respiratory diseases, with specialists participating in the formation of intensive care teams to ensure the quality and safety of intensive care.

-The province has set up 50 critical care teams, each with 27 members.

-Timely production of emergency and severe video teaching materials, accumulated training of more than 180,000 medical staff, and rapid improvement of the critical care capacity of medical institutions at all levels.

-Mobilize village groups and social forces, carry out grid management, find out the base of key populations, establish a guarantee system, implement classified management of key populations, grasp the health status of key populations, find patients with severe tendency in COVID-19 as early as possible, and carry out early treatment nearby as soon as possible to reduce the incidence of severe diseases.

-Establish a piecemeal responsibility system for severe treatment, and implement the provincial-level Baozhou City, Baozhou County, and Baoxiang Town. Severe patients who exceed the ability of primary diagnosis and treatment will be referred to higher-level hospitals for treatment as soon as possible. Counties and urban areas reserve referral and transfer vehicles step by step, and make overall plans at the county level to smooth the referral channel. Establish a patrol and consultation system for emergency support teams for severe treatment to ensure that the treatment of severe patients is orderly, powerful and effective.

—— Expand the treatment resources to achieve "all due", strengthen the treatment force to achieve "all treatment should be done", move forward the prevention and control barrier to ensure "early treatment", and there is no run on severe treatment resources in the province.

Pass forward

Continuously improve the prevention and control ability of rural epidemic situation

Rural areas are an important gateway for epidemic prevention and control and the "last mile" to ensure people’s health. "Forward Pass" is the key work of epidemic prevention and control in urban and rural areas of our province. Combined with the actual situation, our province actively carries out early preparation, early investigation, early identification, early intervention and early referral to comprehensively promote the prevention and control of epidemic situation in rural areas. At present, the situation of medical treatment in rural areas of the province is generally stable, and the epidemic peak has passed one after another.

Honghe Hani and Yi Autonomous Prefecture set up a patrol team to prevent severe diseases, and carried out patrol dynamic monitoring for people aged 65 and over with 8 basic diseases; Yanshan County, Wenshan Zhuang and Miao Autonomous Prefecture, established the responsibility system for the guarantee of people living alone, and strengthened the monitoring and follow-up of health status; Xinping County, Yuxi City, conducts classified management training for grass-roots medical staff, and sends doctors to serve at the station …

In order to prevent mild illness from turning into severe illness, 118 counties in the province have built close county medical communities to give full play to the role of leading hospitals, greatly expand ICU beds and enhance the ability of severe treatment. At present, the province has organized patrol teams to enter villages and households, dispatched 1,370 patrol teams to serve and patrol in villages, comprehensively investigated 5,264,300 elderly people over 65 years old, and achieved accurate classification and identification. On-site activation of 28,000 village team members and sinking of 6,500 cadres and households, and high-frequency follow-up of key populations.

There are 1481 fever clinics in township hospitals (community health service centers) in the province, and 13588 village clinics should be open. At present, more than 90% township hospitals can provide oxygen therapy services for the masses. Organized more than 50,000 grassroots medical and health personnel in the province to participate in a series of trainings on medical treatment of infection in Covid-19. Township hospitals and rural family doctors in the province provided 1,425,800 person-times of health services and distributed "health and epidemic prevention kits". Accurate distribution of antipyretic and analgesic drugs, cough medicine, small molecular antiviral drugs, raw materials and formulas of traditional Chinese medicine decoction to the grassroots. 12 kinds of hospital preparations were urgently approved, and 46 kinds of hospital preparations were included in the drug list (9 kinds of ethnic medicines such as Yi, Miao and Dai).

The relevant person in charge of the epidemic prevention and control team of the headquarters said that with the normal operation of borders and ports resumed, in order to prevent the risk of new mutant input, the province strengthened virus gene sequencing, closely monitored and found new mutant input in time, and quickly responded to disposal.

Dawn is just ahead, and persistence is victory. Jiang Xu, head of the medical treatment team of the headquarters, said that in the next step, our province will improve the diagnosis and treatment measures, increase drug procurement, do a good job in ensuring blood supply, ensure the smooth flow of the "120" call for help, continue to promote vaccination for the elderly, and earnestly safeguard the lives and health of the people.

CCTV News:November 1st is World Influenza Day. As the weather turns cold, influenza gradually enters a seasonal active period, and influenza vaccination everywhere also enters a peak period. What is the epidemic trend of influenza in China this winter and next spring? How can we do a good job of prevention and scientific response?

In a number of community health service centers in Taiyuan, Shanxi, Xiamen, Fujian and other places, citizens are being vaccinated against influenza in an orderly manner, and many of them have come with their children. According to the medical staff in Xiamen, the local influenza vaccine stocks are relatively sufficient at present, and citizens can make an appointment in advance.

According to experts, according to the monitoring situation of sentinel hospitals nationwide, at present, influenza activities in China are on the rise.

According to experts, everyone is susceptible to the flu. However, the severity of flu symptoms varies among different people.

Jiang Hongni, member of Pulmonary Angiology Group of Chinese Medical Association:Children under 5 years old, especially children under 2 years old, older people over 65 years old, some people with basic diseases, and some pregnant women are also susceptible to influenza.

According to experts, the symptoms of influenza are relatively serious, mainly manifested as high fever and systemic symptoms, including headache, muscle and joint pain all over the body; The common cold and fever last for a relatively short time, with mild systemic symptoms and rapid recovery. If you have the flu, you should seek medical treatment as soon as possible in case of critical symptoms, so as to avoid blind or inappropriate use of antibacterial drugs.

Experts remind that to prevent influenza, everyone should wear masks and get flu vaccine while improving their immunity. Due to the different strains of influenza virus every year, the influenza vaccine will be adjusted accordingly, and the influenza antibody is not effective for life, so it is recommended that the public be vaccinated again every year.

Jiang Hongni, member of Pulmonary Angiology Group of Chinese Medical Association:Only a few people are not suitable for vaccination, such as very obvious allergic symptoms, especially those who have been vaccinated before, and there are diseases with this immune system. In addition, if the patient has a fever recently or has been vaccinated with other vaccines in the last month, vaccination can be suspended.

As a new season drama series of "Fog Theater", the opening of "Daughter Coming Back" has aroused the attention and heated discussion of the audience, and it has been highly praised because of its "brain burning" of the plot and the online performance of the actors, and even praised "the return of Fog Theater". However, in the middle of the series, the looseness of the follow-up plot and the rationality of the narrative were questioned by the audience, which led to the continuous decline of word of mouth, and the Douban score dropped to the passing line at the end. It can be said that "Daughter Coming Back" can’t escape the fate that the original suspense online drama of "Misty Theater" has a high reputation and the audience’s expectation has failed, and its narrative defect has also become a microcosm of the deep-seated problems of domestic suspense online drama.

If we count from the crime of undocumented in 2017, the domestic suspense online drama represented by "Fog Theater" has become a very subdivided type of online drama. Thanks to the development of genre models of suspense film and television works in Europe, America and Japan, as well as the literary foundation of Zi Jinchen’s original novels, and the participation of a group of directors with European and American film and television professional backgrounds, the domestic suspense online drama has set off a creative upsurge: after the crime without a license and chasing after the murder in the daytime aroused the audience’s expectation, the popularity and high reputation of Hidden Corner and Silent Truth in 2020 further established the status of "fog theater" as an industry drama, which gave birth to suspense. However, since then, the original script of Fog Theater has not been explored smoothly due to the defects of suspense narration, although the series such as Goodbye that Day, Fog in the Eight Diagrams Pavilion, Who is the murderer, Deadly Wish and Gold Rush have gathered a cast and production team that can not be underestimated, presenting an overall industry dilemma of the original domestic suspense online drama.

Generally speaking, domestic suspense online dramas, including "Misty Theater", follow a narrative mode of "social school" reasoning that combines suspense with reality. This choice is not only related to the policy advocacy of realistic themes of local film and television dramas, but also the communication strategy of online drama producers trying to break the genre boundaries and break the circle of audiences with realistic topics. At a deeper level, it is also the consistent cultural practice of local film and television dramas to highlight the theme of family humanity and social issues. Therefore, under the label of "crime" and "suspense", most of the dramas of "Fog Theater" highlight the human evil brought by family of origin and social power. For example, The Hidden Corner, The Fog in the Octagon Pavilion, Very Witness and Ten-Day Game all involve family relations issues that Chinese is particularly concerned about. Different from the hard reasoning that pays attention to the detective’s puzzle solving process, the social reasoning suspense drama pays more attention to the deep integration of social factors and human problems, and its puzzle solving process lies in showing the deep-seated human evil step by step, and pays more attention to the deep-seated social problems of all people doing evil in the context of a specific era. For example, the society and power system revealed in Silent Truth. This means that there is a close combination between this social problem consciousness and narrative suspense puzzles: in the narrative process of "throwing puzzles-solving puzzles-uncovering puzzles",Construct the rationality and logic of solid details, plots and characters’ behaviors, so that genre narration and social problems can be deeply integrated. By this measure, The Daughter Who Came Back has representatively exposed the narrative defects faced by local suspense online dramas.

Daughter Back is still a social reasoning network drama with the theme of family suspense. The drama is set in Tanling County, which was developed in the southwest of China in 1997 due to the third-line construction. It tells the story of Chen Youxi, a young girl adopted by Jieshan Welfare Institute. Xiaoxiu, a good friend who works as a home nanny in Li Chengdong, director of the county fertilizer factory office, mysteriously disappeared after discovering the Li family’s secret. In order to find the mystery of Xiaoxiu’s disappearance, she fled the welfare home and came to Tanling, pretending that Li Wenwen, the daughter of the Li family who had been missing for many years, sneaked into the Li family to find clues. From the perspective of Chen Youxi as an intruder, with the help of Xiao Xiu’s prospective boyfriend Cheng Wei, the drama gradually discovers the secrets and sins of the Li family through multiple struggles with his mother Liao Suifang, his father Li Chengdong and Liao Suifang’s lover Wang Zhongjiang. As a family suspense drama, The Daughter Who Came Back focuses on the complex game between the family members involved in the murder case, and how the characters form the "hunter" and "prey" and the relationship between the strong and the weak in various human motives and actions: Chen Youxi, as an intruder, seems to have the initiative, but in fact his identity and actions are in Liao Suifang’s hands; However, Li Chengdong, a weak husband in the marriage relationship, was very humble and obedient to keep Liao Suifang.In fact, it is precisely the perpetrators with the deepest intentions; And mentally retarded Li Wenzhuo seems to be kind and powerless. Is he a real murderer … … The series brings questions about who killed Xiaoxiu, the mystery of Li Wenwen’s death and whether Li Wenzhuo is really stupid or fake. The calmness and lust behind Liao Suifang, played by Mei Ting, and the complex character of Li Chengdong, played by Yanhui Wang, which is honest and humble on the surface, make the reverse relationship between these characters and the hidden level of human nature behind the murder case better presented.

However, similar to other social mystery dramas in Misty Theater, Daughter Coming Back has three obvious narrative defects, which make the narrative tension constructed by the contrast between the actor’s superb performance and the characters still unable to save its reputation:

First of all, as a suspense drama of social reasoning, its realistic problem consciousness does not go deep into the internal texture of narration, and stays at the superficial atmosphere of the times and the superficial psychological consciousness level, which fails to become a part of the deep-seated characters’ behavioral motives, thus showing a typical "sense of decoration of the times" drawback.Although director Lv Xing himself emphasized the typology and problem consciousness of creation, and published a document stressing that his narrative should focus on showing the relationship between the background of fund-raising tide, third-line construction and laid-off tide, detention and repatriation system, Qigong fever and other backgrounds existing in China society in the late 1990s and the mentality and fate of the characters at that time, from the perspective of drama narrative, these did not really form the deep-seated logic of his narrative, nor did they become a part of clues. The most important background in the play can be said to be the decline of the chemical fertilizer plant and the laid-off workers, which constitutes the background of Li Chengdong’s psychological loss and his fragile "pride" (used to show off in front of Liao Suifang as a red man of the factory director), but the real problem between him and Liao Suifang lies in his desire and Liao Suifang’s lack of love for him. Similarly, Wang Zhongjiang, who is his rival in love, is involved in the social context of wealth, and its complex relationship (how to get out of the chemical fertilizer factory, what it has experienced, why people are attached to raising funds, and how to have an accident) how to form an image of the relationship between the three people, which is vague in the play, not given an explanation and presentation, and not even entered the narrative context. Wang Zhongjiang’s plot line and the weakening consciousness of social problems behind it are difficult to support the narrative significance that the director’s intention and narrative background may bring, and eventually become a simple background decoration.

Secondly, as a typed narrative, both social reasoning and case reasoning need to follow the principle of "Puzzle Throwing — — The emergence of evidence — — The revelation of the mystery runs through the basic logic, which makes the progress of the plot and the audience’s participation form an intellectual wrestling with each other. However, there is an obvious problem of "puzzle loss" in Daughter Back, which leads to the separation between narrative progress and audience’s participation.In the first half of the plot, The Daughter Who Comes Back throws at least four puzzles: (1) The mystery of the identity of the monkey masked man; (2) Xiaoxiu leaves or the mystery of death (whether to leave or not? What is Xiaoxiu’s real personality? Who killed Xiao Xiu? How did Xiao Xiu die? What about Xiao Xiu’s body? (3) The mystery of whether Li Wenzhuo really burned his brain and whether he killed people; (4) The mystery of Li Wenwen’s disappearance and death, etc. These problems all lead to a direction of "all people are evil", and also make the criticism of the universal evil of human nature behind an era context a possible construction of the theme that the audience expects. However, after the series throws out questions, the plot is constantly turning over, and the focus of the questions is constantly changing. For the original puzzles, the answers are revealed in an effortless and narrative way: for example, the monkey mask man is just a rogue, and coincidentally reveals the mystery that Li Wenwen died in a washing machine. And why is Li Wenzhuo there every time the Monkey Mask Man appears? For another example, what kind of person is Xiaoxiu, and is there a relationship between her death and her real personality? … … None of these questions give clear answers in the play. Although the series gives many fragmentary clues, Wang Zhongjiang’s positive personality and light death lead to a lot of redundant details and plots being invalid. In the end, taking Li Chengdong as the subject of doing evil and accepting the crime runs counter to the audience’s guess that all the people are doing evil, which greatly weakens the intelligence of the narrative and the depth of the theme.

Thirdly, from the level of suspense narrative, narrative rationality is the most critical factor for the success of suspense drama, and the rationality of details, plots and characters constitutes three key elements of suspense narrative rationality, but The Daughter Who Came Back has obvious rationality defects in these three aspects.For example, the fact that Liao Suifang went to grandma Cheng Wei’s house to look for Chen Youxi’s things and glanced at the photos of Cheng Wei’s parents on the wall was not necessarily related to the narrative; As a patient in a mental hospital, it is also questionable how MengMeng got the key to a mental hospital and got in and out freely. In a suspense drama supported by solid realistic details, it is also abrupt to take the "flying butterfly" as the confirmation details of the relationship between Li Wenzhuo and Li Wenwen. On the rationality of the plot, what is criticized is why Wang Zhongjiang’s family can let anyone in and out freely, so that Cheng Wei can sneak in twice to steal blood tests and steal videos; And why was Liao Suifang so calm when she saw the obviously false report on the DNA report? Furthermore, from the character, Liao Suifang, who is so smart and careful, drank Li Chengdong’s poisonous soup defenseless before going to the Public Security Bureau in the last episode? And Chen Youxi can see that Li Chengdong lied and admitted to killing Xiaoxiu, but he was so out of control after Li Wenzhuo said he choked Xiaoxiu? And so on, all confuse the audience. This separation of details, plots and characters is a serious damage to narrative rationality.

The above-mentioned problems of "The Daughter Coming Back" are the common problems existing in the original suspense online drama of "Misty Theater". Without the adaptation of Zi Jinchen’s original novel, the creation of the original suspense narrative script of social school reasoning, the deep-seated narrative integration of social problem consciousness, the construction of typed puzzle narrative and the solid construction of logical rationality are all key issues to test the creation of local suspense online drama. How to get rid of the "sense of decoration of the times" and make people get a deep social representation of sexual sin, how to avoid the "puzzle loss" and how to form the narrative tension of audience participation in suspense narrative, and how to get solid details support through the multi-level rationality of logic, fundamentally determine how far the local original suspense online drama can go.

CCTV News:The Central Meteorological Observatory continued to issue six early warnings on February 21, and it is expected that the large-scale rain, snow and freezing weather in the central and eastern regions will continue on February 21 and enter the strongest period of rain and snow.

According to reports, as of noon on the 21 ST, the Central Meteorological Observatory issued six warnings for the third consecutive day, which is extremely rare in the same period. Among them, the orange warning of cold wave is the highest level, and the warning of blizzard is upgraded from the 20th to yellow. Weather such as freezing rain or ice particles may affect at least seven provinces. With the unusually strong warm and humid airflow, it is easy to induce strong convective weather such as thunderstorms and short-term heavy rainfall. This year, the blue warning of strong convective weather was released obviously early, and the subsequent cooling mainly appeared in the south.

Li Ning, a meteorologist from China Meteorological Bureau, explained that the cumulative temperature drop in some parts of southern China will reach or even exceed 20 degrees Celsius. After the temperature drop, there will be frequent rain and snow, which will lead to the continuous significant low temperature in Henan, Hubei, Hunan and other places. The main duration is from 23rd to 27th, so we should pay attention to keeping warm. In addition, the yellow warning of blizzard will continue to take effect on February 21, and some areas in Shandong, Henan and Hubei will continue to encounter heavy snowstorms. On the south side of the blizzard area, at least seven provinces from Guizhou to Jiangsu will be threatened by freezing weather, among which the freezing rain in Hubei and Hunan will last longer, so we must be vigilant.

In addition to the snowstorm and freezing weather, we can see that the weather changes very frequently in the next six days, such as Wuhan and Changsha. In the next five or six days, it will almost be rainy and snowy every day. Changsha has the longest freezing rain, and Wuhan will also have such complicated precipitation phases as freezing rain, snowfall and rainfall after heavy snowfall.

Experts said that among many forms of precipitation, ice particles and freezing rain are relatively rare, which is related to the thickness of the warm layer in the air. When ice crystals and snowflakes in the high air pass through the warm layer, they will melt. If they re-freeze before reaching the ground, they will fall to the ground as ice particles. When cold water drops at about 0 degrees meet the ground at about 0 degrees, they will quickly freeze and form freezing rain, which is the main cause.

According to the weather situation, Li Ning, a meteorologist of China Meteorological Bureau, said that freezing rain will quickly freeze after it falls to the ground, and with the freezing rain continuing, the thickness of ground ice will continue to increase, which has a greater impact on traffic. In addition to the impact on road traffic travel, it will also cause the wires to be covered with ice, so the impact of freezing rain is even greater for high-speed rail travel and air travel.

Emergency Management Department: Hubei, Henan and Anhui launched a four-level emergency response to low-temperature rain, snow and freezing disasters.

In view of the wide influence of the large-scale freezing process of rain and snow, the complex phase of rain and snow and the large area of freezing rain, the emergency management department launched a four-level emergency response to low-temperature freezing rain and snow disasters in Anhui, Henan and Hubei yesterday (20th).

On February 20th, the Office of the National Disaster Prevention, Mitigation and Relief Committee and the Emergency Management Department, together with the China Meteorological Bureau, continued to organize joint consultations, video dispatching Hebei, Shaanxi, Shanxi, Henan, Shandong, Anhui, Hubei and other provinces, and targeted deployment of prevention and response work in key areas.

At present, it is at the peak of Spring Festival travel rush’s return trip, and the risk of low-temperature rain, snow and freezing disasters is high. At 12: 00 on February 20th, the emergency management department launched a four-level emergency response for Anhui, Henan and Hubei. Relevant regions are required to pay close attention to weather changes, strengthen organizational leadership and overall coordination, give play to the leading role of disaster reduction committees or special command agencies, strengthen joint consultation, judgment and departmental coordination, strengthen emergency rescue forces and materials preset and dispatched, make all preparations for disaster relief in advance, and make every effort to deal with sudden dangers and disasters. The Office of the National Disaster Prevention, Mitigation and Relief Committee sent working groups to Henan, Anhui and Hubei to help guide the prevention and response work.

　　At the Los Angeles Convention and Exhibition Center, gamers are experiencing virtual reality (VR) devices. Bright pictures/vision china

　　With the establishment of virtual reality technology (VR) laboratory in Alibaba, Stormwind TV released the first VR TV, Huawei announced its first generation of VR glasses products, and the VR industry also rose. It can be predicted that in the near future, the wide application of mobile Internet, big data and other information technologies will promote the further development of VR technology. So how is the so-called virtual reality technology realized?

　　1. Frontier disciplines of integrated application of software and hardware.

　　Virtual reality technology (VR) is a computer simulation system technology to create and experience a virtual world. That is to say, VR uses computers to generate a simulation environment, and uses multi-source information fusion for interactive three-dimensional dynamic visual scene and system simulation of entity behavior to immerse users in this environment. Up to now, there is no universal definition of it in the world, but it can generally be considered that it creates another unreal world that is as real, interactive and immersive as possible for human beings outside the real space by using various human-computer interaction technologies, so that human beings can roam in it, experience the most real virtual space and walk in their dreams without any restrictions.

　　VR has been widely used in new media, aerospace, military, engineering and other cutting-edge scientific and technological fields, and will be more widely used in our daily life as an advanced technical means. Because most of the monitors used by virtual reality in human-computer interaction are helmet-mounted enhanced portable display systems, it is one of the most promising application fields of portable display systems. Users only need to wear virtual reality equipment, such as helmets, glasses, etc., and they can feel all kinds of scenes set in the device.

　　VR system generally includes user control systems, such as human motion monitoring, control devices such as joystick, keyboard and mouse, and simulation feedback systems and processing systems for human senses such as vision, hearing, touch, smell and taste, as well as information display systems perceived by human beings, such as monitors, stereos and three-dimensional seats. Among them, visual and auditory control and simulation are the main development direction of VR at present, and helmet-mounted enhanced portable display system is the main product form used by users.

　　2. Construct a virtual space in advance in the computer.

　　VR is an interdisciplinary subject that relies on a large number of computer software technologies such as artificial intelligence, pattern recognition, graphics, bottom interface and new display technology, field sensor technology, force feedback system, wireless and wired communication technology. In essence, VR is the representation of the real world and the realization of dreams; From a technical point of view, it is a comprehensive application of cutting-edge technologies in the fields of software and hardware and an object-oriented comprehensive technology development.

　　VR enables people to experience a fantastic virtual reality while wearing a helmet-mounted enhanced portable viewing system. In fact, these virtual reality scenes use complex software technology to construct a real virtual space in the computer in advance. Every point in the space has many dimensions of information such as coordinates, colors, normals, logical relationships and so on in X, Y and Z. The computer then determines the position of people in the virtual scene through user input devices such as sensors, joysticks and mice, and finally reproduces the picture to the user’s eyes through the computer, thus creating a virtual space.

　　If such a series of tasks can be connected, and the operation time of the whole system is less than the visual retention time of people, users will have the feeling of roaming in the virtual reality world on the virtual image display screen of the head-mounted enhanced portable display system. VR is to create a virtual environment that makes you feel that this is reality. Entertain and attract you through this fictional reality.

　　3.MR— — Break through the boundary between virtual and reality

　　In addition to VR technology, there is also augmented reality technology, namely AR. Now there are only more than 20 authoritative companies in the world conducting research. Google’s technology is relatively mature, and its goal is to put the virtual world in the real world and interact with it on the screen. This technology was first put forward in 1990. With the improvement of the computing power of portable electronic products, it is expected that its application will be more and more extensive.

　　In essence, AR is the interaction between digital media and the real world. The imaging concept of AR and the immersive imaging experience of VR have created a hybrid virtual reality technology, namely MR, which is based on holographic projection reality. At the Microsoft Developer Summit held in June this year, satyanarayana nadella, CEO of Microsoft, emphasized the importance of its hybrid virtual reality technology equipment — — The correct "opening" way of Hololens is neither a VR helmet nor AR glasses. This hybrid virtual reality device holographically projects computer-generated 3D virtual objects into real space, and the wearer of Hololens can interact with 3D virtual animation in real space and trigger corresponding functions. The imaging principle of this kind of MR equipment is different from that of immersive VR equipment. It projects virtual images into real space, but the imaging effect of the projected holographic 3D images breaks through the boundary between virtual and real world.

　　Research and Application of Virtual Reality Technology

　　The focus of NASA’s research on this technology is the real-time simulation of space station manipulation, and they use a lot of cockpit-oriented flight simulation technology. Such as the simulation of the Hubble Space Telescope and the experimental plan of "Virtual Planet Exploration", this project enables the "Virtual Explorer" to use the virtual environment to explore distant planets, and the first goal is Mars.

　　The University of North Carolina is the earliest and most famous university to study virtual reality technology. Their main research includes molecular modeling, aviation driving, surgical simulation, architectural simulation and so on. On the display technology, the university has developed a parallel processing system called Pixel Plane, which helps users to build real-time dynamic display in complex scenes.

　　MIT was originally a pioneer in studying artificial intelligence, robotics, computer graphics and animation. These technologies are the basis of virtual reality technology. In 1985, a media laboratory was established to conduct formal research on virtual environment.

　　The laboratory of man-machine interface technology in Washington Technology Center of the University of Washington plays a leading role in the research of new concepts, and is also conducting research on sensory, perceptual, cognitive and motor control abilities. They introduced the research of virtual reality technology into the fields of education, design, entertainment and manufacturing. For example, Boeing’s V22 transport plane was built in the laboratory before it was put into production.

　　Illinois State University has developed a distributed virtual reality technology system that supports remote collaboration in vehicle design. Engineers from different countries and regions can design in real time through computer networks. In the process of designing a vehicle, various components can share a virtual environment, and can view the video transmission and corresponding positioning direction of any position of the other party. Virtual prototype is adopted in the system, which reduces the time for designing images and new products to enter the market, so that products can be estimated and tested before production, and the quality of products is greatly improved.

　　George Mei Sen University has developed a real-time fluid simulation system in a dynamic virtual environment. In a distributed interactive simulation system, the physical characteristics of complex fluids in the real world are simulated, including simulating ships running across the water, stirring liquids, mixing liquids of different colors, and the influence of rain on the terrain.

By 2030, the city’s agricultural production informatization rate is planned to reach about 50%.

　　Third, the platform empowers to build a new ecosystem of science and technology services

　　The "Program" emphasizes the construction of two platforms, namely, science and technology consulting training and science and technology service management, to provide strong support for agricultural science and technology and production services:

　　1, science and technology consulting training platform

　　Integrate expert resources, strengthen agricultural macro-language model training, provide all-weather technical guidance through AI intelligent consultation, select 4-5 key industrial service targets, demonstrate and promote intelligent consultation service systems, and cultivate 2-3 demonstration models. Strengthen online live training and offline training. It is estimated that there will be 65 online live training sessions with 150,000 person-times, organize quality training for key personnel of grass-roots agricultural extension system, and cultivate more than 700 key personnel of agricultural extension with proficient business and excellent service.

　　2, science and technology service management platform

　　Build a big data platform for agriculture and rural areas in Beijing, realize the digital management of the whole business process, promote the exchange and sharing of relevant data between the Ministry of Agriculture and Rural Affairs and the city, promote the integrated application of cities, districts, towns and villages, and strengthen the application of data governance and data mining. Build a four-level science and technology management platform with service base, demonstration base, expert workstation and comprehensive application scenario to realize the comprehensive management of service network, service data and service evaluation.

　　In order to ensure the smooth implementation of the "Implementation Plan on Further Enhancing the Role of Agricultural Science and Technology Demonstration and Production Service System", Beijing Agriculture and Rural Bureau will play the role of overall planning, and join forces with the Municipal Academy of Agricultural and Forestry Sciences, universities and urban extension units and enterprises to promote the scientific and technological demonstration work. All promotion units will strengthen horizontal cooperation, realize the promotion of the whole industrial chain, and do their best to do a good job in production and service.

　　The promulgation of the "Program" marks that Beijing’s agricultural science and technology demonstration and production services have entered a new stage of systematization, digitalization and precision. In the next step, Beijing Agriculture and Rural Bureau will fully promote the implementation of the Plan, and ensure that the capital agriculture will achieve its phased goals in 2025 and its long-term goals in 3-5 years through the way of "departmental collaboration+policy integration+demonstration and guidance".

　　Generally speaking, the Implementation Plan on Further Enhancing the Role of Agricultural Science and Technology Demonstration and Production Service System is an important measure for Beijing science and technology to promote agricultural modernization. Through systematic work reform and innovation, Beijing will improve the agricultural science and technology and production service system, accelerate the transformation of scientific and technological achievements, improve service accuracy, support the development of urban modern agriculture, and provide a "Beijing model" for the development of urban modern agriculture in China.
