　　Have you searched the Internet for "What hurts me? Is there something wrong with me?"? The answer may not be satisfactory. However, with the emergence of large-scale natural language models (LLM) such as ChatGPT, people began to try to use it to answer medical questions or medical knowledge.

　　However, is it reliable?

　　As far as it is concerned, the answer given by artificial intelligence (AI) is accurate. However, James Davenport, a professor in university of bath, pointed out the difference between medical questions and actual medical practice. He believed that "medical practice is not just about answering medical questions. If we just answer medical questions, we don’t need to teach hospitals, and doctors don’t need to receive years of training after academic courses."

　　In view of all kinds of doubts, in a recent paper published by Nature, the world’s top artificial intelligence experts showed a benchmark to evaluate how well large-scale natural language models can solve people’s medical problems.

　　The existing model is not perfect.

　　The latest assessment comes from Google Research and Deep Thinking. Experts believe that the artificial intelligence model has many potentials in the medical field, including knowledge retrieval and supporting clinical decision-making. However, the existing model is not perfect, for example, it may fabricate convincing medical error information, or include prejudice to aggravate health inequality. Therefore, it is necessary to evaluate their clinical knowledge.

　　Relevant assessments have not been without before. However, in the past, it usually relied on automated evaluation of limited benchmarks, such as individual medical test scores. This is translated into the real world, and both reliability and value are lacking.

　　Moreover, when people turn to the Internet to obtain medical information, they will encounter "information overload" and then choose the worst one from 10 possible diagnoses, thus bearing a lot of unnecessary pressure.

　　The research team hopes that the language model can provide short expert opinions, be unbiased, indicate its citation source, and reasonably express uncertainty.

　　What is the LLM performance of 540 billion parameters?

　　In order to evaluate the ability of LLM to encode clinical knowledge, Xie Kufei Aziz, an expert from Google Research Institute, and his colleagues discussed their ability to answer medical questions. The team put forward a benchmark called "MultiMedQA QA": it combines six existing question-answering data sets covering professional medical care, research and consumer inquiries and "HealthSearch QA" & mdash; — This is a new data set, which contains 3173 medical questions searched online.

　　The team then evaluated PaLM (a 540 billion parameter LLM) and its variant Flan-PaLM. They found that Flan-PaLM reached the most advanced level in some data sets. Flan-PaLM surpassed the most advanced LLM by 17% in the MedQA data set integrating the questions of American medical license examination.

　　However, although Flan-PaLM scored well in multiple-choice questions, further evaluation shows that it has a gap in answering consumers’ medical questions.

　　LLM of specialized medicine is encouraging.

　　In order to solve this problem, artificial intelligence experts use a method called design instruction fine-tuning to further debug Flan-PaLM to adapt to the medical field. At the same time, the researcher introduced an LLM— — Med-PaLM。

　　Fine-tuning design instructions is an effective way to make general LLM suitable for new professional fields. The resulting model Med-PaLM is encouraging in the trial evaluation. For example, Flan-PaLM scored by a group of doctors is only 61.9% consistent with the scientific consensus, and Med-PaLM scored 92.6%, which is equivalent to the answers made by doctors (92.9%). Similarly, 29.7% of Flan-PaLM’s answers were rated as likely to lead to harmful results, and only 5.8% of Med-PaLM’s answers were equivalent to those of doctors (6.5%).

　　The research team mentioned that although the results are promising, it is necessary to make further evaluation, especially in terms of safety, fairness and prejudice.

　　In other words, there are still many limitations to overcome before the clinical application of LLM is feasible.

　　Xinhua News Agency, Tianjin, June 28th-China has been an active advocate and practitioner of South-South cooperation for more than 70 years. Many people who are attending the 14th Summer Davos Forum in Tianjin, China said that China is playing an increasingly important role in global South-South cooperation with its accumulated experience, technology and talent advantages in agricultural technology popularization, global poverty reduction and public health, providing a "China sample" for reference.

　　China agricultural technology drives bumper harvest.

　　To achieve the goal of global hunger eradication, Africa is an important puzzle. The food supply here is seriously threatened by climate change and land desertification, and the agricultural technology in China has provided important help for increasing local food production and improving food security.

　　In Mozambique, Wanbao Mosang Agricultural Park, which china-africa development fund participated in, is a large-scale rice planting project, which has significantly improved the local rice planting and rice processing technology; In Kenya, the field micro-rainwater harvesting technology from China was applied in the local demonstration area to grow corn, and the yield increased by 99% to 240%. In Burundi, the expert group of China selected and introduced eight kinds of rice suitable for the local area, which solved the historical problem that the local mountainous area often lost production or even failed to harvest due to rice blast.

　　China has built a number of agricultural technology demonstration centers in Africa, and projects such as "Demonstration Project of Increasing Corn Yield by Thousands of Households and Ten Thousand Mu" have blossomed locally.

　　In the eyes of South African delegate Malelai, China’s agricultural technology has brought tangible benefits in agricultural innovation, poverty alleviation and food security. He said that he expected more cooperation between Africa and China in food security and mitigation of the impact of climate change.

　　According to the data of the Ministry of Agriculture and Rural Affairs of China, by 2021, China has sent more than 2,000 agricultural experts and technicians to more than 70 countries and regions, and promoted and demonstrated more than 1,500 agricultural technologies to many countries, driving the project to increase production by 40% to 70% on average.

　　Medical and health experience in China promotes health.

　　This year marks the 60th anniversary of the dispatch of China’s foreign aid medical team. Over the past 60 years, China has sent 30,000 medical personnel to 76 countries and regions around the world, treating 290 million patients.

　　China, together with its partners in developing countries, shared the experience gained in the field of public health in China, shared public health products such as vaccines, and made joint efforts to reduce the disease burden in developing countries and promote global health governance.

　　The global malaria burden is mainly concentrated in southern countries. There were still 30 million malaria cases in China from the early days of the founding of the People’s Republic of China. By 2017, the number of local malaria cases was reported to be zero, and by 2021, it was certified by the World Health Organization as the national malaria elimination certification … … China’s achievements in malaria control provide a reference for overcoming malaria problems and promoting global health.

　　In Tanzania, using China’s barefoot doctor model for reference, villagers were recruited and trained to become the core medical staff or volunteers of local medical teams. Learn the work standard of "1-3-7" malaria case report and detection in China, that is, complete the case report within 1 day, complete the case review and epidemiological investigation within 3 days, and carry out the investigation and disposal of epidemic spots within 7 days; Pipequine dihydroartemisinin phosphate tablets produced in China have also been popularized in pilot areas.

　　Ren Minghui, a professor at Peking University School of Public Health and former assistant director-general of the World Health Organization, said in an interview with Xinhua News Agency during the forum that South-South cooperation in China is open, inclusive and oriented to the needs of South-South countries. Whether China’s anti-malaria technical scheme has been promoted by WHO for many times, or China’s aid to build medical infrastructure and China’s pharmaceutical enterprises’ overseas localized production or technology transfer, China has provided a reference, further localized and concrete scheme for southern countries to strengthen health system construction.

　　China’s program helps to meet global challenges.

　　At present, international geopolitical conflicts have intensified, North-South cooperation has slowed down, and the development gap has widened, thus facing many challenges in achieving the goal of sustainable development in 2030. According to United Nations statistics, there are still more than 800 million people starving and 350 million people in need of humanitarian assistance in the world, and the momentum of implementing the sustainable development goals has obviously slowed down.

　　China, with its own development path, has provided the world with a feasible and reproducible reference, and also contributed China’s plan and China’s wisdom to jointly deal with global challenges.

　　Zhang Jianping, deputy director of the Academic Committee of the Institute of International Trade and Economic Cooperation of the Ministry of Commerce, said that China has set a development model for the southern countries. China’s participation in South-South cooperation does not attach political conditions and requirements like western countries, which provides opportunities for southern countries to improve their own capacity building, development level and development efficiency.

　　Eliminating poverty is a common challenge facing mankind. As the country with the largest poverty reduction population in the world, China has contributed more than 70% to global poverty reduction, creating a miracle in the history of poverty reduction in the world. Poverty reduction in China has become a research sample of more and more countries and international organizations.

　　Facing the challenge of global climate change, in 2015, China set up the China South-South Cooperation Fund on Climate Change with 20 billion yuan; Since 2016, China has launched 10 low-carbon demonstration zones, 100 climate change mitigation and adaptation projects, and 1,000 cooperation projects to cope with climate change training places in developing countries, and implemented more than 200 foreign aid projects to cope with climate change.

　　Zhu Min, vice chairman of China International Economic Exchange Center, told Xinhua that China has accumulated experience and technology in carbon neutral macro management, technological innovation and new industrial layout. At present, China’s photovoltaic manufacturing industry accounts for 90% of the global production capacity and is an important source country of global wind power equipment and electric vehicles. "China has great potential to promote the green transformation of developing countries in terms of carbon neutrality."

　　Sri Lankan Foreign Minister Sabri said that Sri Lanka’s economy has achieved remarkable growth since China invested in the local area and started infrastructure construction. South-South cooperation is an important mechanism to jointly promote the solution of global challenges, in which China plays an important role.

　　The "China sample" of South-South cooperation provides enlightenment and reference for developing countries from the perspective of global development. In the long run, more global governance has explored new models and new paths different from those in the West. (Reporter Zhang Miao, Xu Supei, Bai Jiali, Henry Hui Wang, Zhang Yuqi)

　

Musicians’ income distribution map, the data comes from "2019 China Musicians’ Living Situation Report".

In addition to the head musicians, more musicians have become the "silent majority", and they urgently need traffic exposure and income support. At present, mainstream music platforms have launched musician support programs to provide musicians with all-round creative support.

For musicians, it is good that someone is willing to support their musical dreams, but in the face of many support plans and hype, how do you choose between various support plans according to your own situation?

Now, we will compare the support plans of QQ Music, Netease Cloud Music and Xiami Music in detail, and sort out their differences and advantages and disadvantages, hoping to give some references and suggestions to musicians and friends.

First, the copyright dispute, the battlefield entered the upstream of the industry

As we all know, the music platform’s support plan is not just for public welfare, at least. The music platform hopes to incubate a group of singers who come out of their own homes, and establish the exclusive signboard of the platform while attracting more users.

This involves a problem that musicians didn’t pay much attention to before, but now they are very cautious-copyright.

In Netease Cloud’s support plan, the terms implied that all the works uploaded by musicians belong to the platform, and the content of the copyright agreement is directly related to the musician’s income and whether the platform will tamper with the musician’s works.

At the beginning of 2019, @ Flynn’s voice reminded the majority of musicians, and the unfair terms of Netease Cloud Music severely bound the copyright of musicians’ works. After the incident was exposed, it had a big impact on the platform.

　

Flynn’s exposure article at that time

As we all know, the competition for copyright among various music platforms is extremely fierce, and making up for the copyright disadvantage is the potential demand of Netease Cloud and Shrimp. The copyright fortress of QQ music is very strong. In the official tweet of QQ music open platform, it is clearly stated that the content of "song authorization" and "musician signing" will be launched in the near future, and there will be a transparent and perfect system.

Relatively speaking, the purpose of the support plan launched by Shrimp and Netease Cloud is more to make up for the copyright disadvantage; QQ music, which has already established a strong copyright barrier, is more pure, that is, it really gives musicians a good growth and creative environment.

Second, the domain line, group-oriented tolerance and segmentation

In Xiami Music’s early years, relying on minority tastes and literary temperament, a large number of young artists were harvested. From the "unexposed" musicians excavated by the light-seeking plan, it can be seen that the main audience of dried shrimp is indie musician, mainly rock and electronic musicians.

Netease Cloud Music’s Stone Project is also dedicated to the young indie musician, and has been digging in the vertical fields of rock and hip-hop. The "rock season" that ended before was won by the Summer Invasion Planning Band, which began to appear in major music festivals. Next, Project Stone will continue to pay attention to the long tail music in the field of focus, and it is expected to tap musicians in the fields of hip-hop and electronics.

QQ Music Support Program is also more widely oriented to groups, except rock, rap, pop, classical, Urban, ACG, Chinese style, including cover artists and video artists, all of which can enter the QQ music open platform. Compared with other platforms’ strategies of focusing on feelings, QQ music gives consideration to feelings and mass market by virtue of user scale, just like owning the copyrights of Modern Sky and Jewell at the same time. No matter what kind of music you are good at, QQ music should always cover fans who like you.

　

Generally speaking, QQ music open platform is the most inclusive, which is a good thing for more independent musicians; Netease Cloud and Shrimp are more focused on the excavation of long tail music, and of course the threshold requirements are higher; The specific choice depends on your own needs and ambitions.

Third, traffic is king, which is better or worse under the transparent mechanism?

Here, we mainly analyze QQ Music and Netease Cloud Music. Both of their musician support plans have detailed in-terminal points exchange traffic rules, while other platforms only generally express "10 billion exposure" and "traffic support", so we can’t get more details.

QQ Music takes "Yinbei" as the integral unit, and Netease Cloud Music takes "Yundou" as the integral unit, so we can intuitively compare their concerns about the flow of musicians by comparing the difficulty and value of obtaining the integral.

Integral acquisition mode

　

From the above figure, the difference between the two platforms in the way of obtaining points is not big. QQ music mainly includes two aspects: "the amount of existing works played" and "new fans added". The more plays, the more fans there are, and the more sound shells there are, and the more real plays can promote this cycle, which I like better.

Difficulty and value of integral acquisition

In order to facilitate everyone’s understanding, we can explain it from specific scenarios:
Let’s assume that a musician who has just entered the platform completes the basic tasks of the platform such as daily sign-in and fan interaction on time and in quantity in the first month. What can he get on the two platforms after one month?

　

In QQ music, 4550 Yinbei can get 4550 songs to play and promote, a private letter from fans, and two months of luxury green diamonds;

In Netease Cloud Music, you need to accumulate 500 cloud beans to redeem a traffic packet, so 81 cloud beans can’t get anything for the time being.

Assuming that this operation process continues and musicians want to obtain 10K traffic resources, what do they need Takuwa to do on both platforms?

　

QQ music 10K traffic = 6 tasks completed in 2 months.
Netease cloud music 10K traffic = 11 tasks completed in 5 months.

Through the above comparison, we further summarize the two platforms from the perspective of traffic:
1. There are more ways to obtain QQ music than Netease Cloud Music, and the conditions for obtaining it are easier.
2, QQ music traffic is simple and clear; Netease cloud music traffic acquisition threshold is relatively high, and QQ music "Yinbei" is more valuable than Netease cloud’s "Yundou". In addition, in Netease Cloud Music, only 500 cloud beans can be packaged in exchange for 10,000 traffic packets, which is equivalent to 10,000 exposures, but not equal to the broadcast volume. In QQ music, 1 tone is equal to 1 successful broadcast, which is too much compared with "exposure".

In contrast, perhaps due to the gap between the ability of background distribution technology and the size of users, the traffic support system of QQ music is far higher than Netease Cloud in terms of the convenience and difficulty of obtaining, the clarity of rules and the actual exposure value.

It is worth mentioning that QQ music not only provides flow support for musicians, but also provides a mature work management system, which is really worry-free at present-many complicated signing and authorization issues we have seen are not only cumbersome, but also easy to pit. In the release cycle of works, it is particularly inconvenient to upload and review at different levels. This time, QQ music directly simplifies the whole process of music authorization, release and operation, so that musicians can easily complete most operations directly on the platform, and no longer face the "dilemma" of "choosing platform traffic support, they can only exhaust their efforts under various complicated terms and conditions".

Fourth, directly poke the pain point, only with financial support can we show sincerity.

As mentioned earlier, lack of money and difficulty in promotion are two major problems faced by everyone who makes music. Netease Cloud Stone Project provides disguised financial support for the champion by providing recording records and shooting MV. The Shrimp-and-Light Project also provides services such as music recording for musicians, saving money for musicians.

At present, QQ Music hasn’t given a reply in terms of funds, but from the detailed rules of traffic support and opening to all musicians, we can see QQ Music’s determination to do a good job in this musician support plan. The official tweet said that "a very sincere cash-out plan will be announced soon", and Tencent, which has a big family, will definitely have more real support in terms of funds, which is worth our expectation.

　

At present, the music market in China is in the upward stage, and the awareness of copyright in the whole industry is increasing. Respecting intellectual property rights has become the consensus of the online students, and paying for listening to music has become a trend. Therefore, musicians have begun to see the way forward by relying on their works. I also hope that the musician support programs of each platform can really help every enthusiastic and simple musician, so that their harvest can match their talents, and the platform can expand its influence through the support programs and contribute to the future of Chinese music.

According to Counterpoint Research data, Huawei returned to the top position in smartphone sales in the first two weeks of 2024. In the first six weeks of 2024, the overall smartphone sales in China decreased by 7% year-on-year, while Huawei’s mobile phones increased by 64% year-on-year, ranking second with a market share of 17%. The report mentioned that Huawei Mate 60 series continued to attract and meet strong market demand and became one of the few bright spots at the beginning of this year. In addition, the data also shows that Huawei’s folding screen market ranked first in the fourth quarter of last year, with a market share of 51.2%.

In 2023, with the help of the hot sale of Mate60 series, Huawei’s terminal business ended the previous two consecutive years of revenue decline and achieved revenue growth. This change not only brought positive effects to Huawei itself, but also injected new vitality into the entire mobile phone industry.

On March 29th, Huawei officially released its 2023 annual report.The company achieved an annual operating income of 704.2 billion yuan and a net profit of 87 billion yuan.According to the report, in 2023, Huawei’s R&D investment reached 164.7 billion yuan, accounting for 23.4% of the annual income, and the accumulated R&D expenditure in ten years exceeded 1,110 billion yuan.

Hu Houkun, Huawei’s rotating chairman, said, "In 2023, the overall operation of the Group was in line with expectations. In the past few years, Huawei has experienced many tests and is constantly growing in challenges. It is the trust and support of customers, partners and all walks of life that has helped Huawei survive and develop. "

According to the analysis of Shanghai Securities Research Report, benefiting from the strong return of Huawei Mate60 series, Huawei’s terminal business including mobile phones achieved a substantial increase in revenue in 2023, with sales revenue of 251.5 billion yuan, up 17.3% year-on-year, becoming the growth engine of Huawei’s performance.With the release of HarmonyOS Xinghe Edition in the second half of the year, Pura70 series is expected to be the first terminal to experience native applications in HarmonyOS.

Spoiler Huawei’s key strategy in 2024

　

In addition, it is worth noting that on April 17, the Huawei Analyst Conference opened in Shenzhen, and more than 500 analysts and think tanks around the world discussed topics such as frontier trends in the intelligent age and industrial development direction.

On April 1st, Xu Zhijun, the rotating chairman and vice chairman of Huawei, delivered a keynote speech at the conference to introduce Huawei’s key strategy in 2024, focusing on the key measures to "seize the strategic opportunity of intelligence and promote comprehensive intelligence".

Xu Zhijun said that on the one hand, the comprehensive intelligent strategy refers to providing sustainable computing power for the development of key technologies of artificial intelligence, especially large model training and reasoning, and building a win-win ecology; On the other hand, AI is used to enhance the competitiveness of Huawei’s products and solutions, including: using Ascension Cloud Services and Pangu Big Model to enable industry intelligence, creating an autonomous driving network to revolutionize the operation and maintenance mode of communication networks, creating an autonomous driving solution, and finally realizing unmanned driving, and creating a super smart assistant gadget based on Pangu Big Model.

"At the same time, introducing AI into Huawei’s internal management continues to improve operational efficiency, investing in AI basic research to promote continuous innovation of artificial intelligence, actively participating in global AI governance, and doing AI governance well in product design and before product release are also essential key measures for strategic landing." Xu Zhijun said.

Xu Zhijun introduced that since the release of Huawei’s AI strategy and full-stack full-scenario AI solution in October 2018, Huawei has been firmly implementing the strategy and building AI solutions, and continuously promoting comprehensive intelligence.

Zhou Hong, Dean of Huawei Strategic Research Institute, shared his thoughts and prospects for the intelligent age at the meeting.

He said that in the next 20 years, human society will accelerate towards the era of comprehensive intelligence.

"Information perception, communication, calculation and control will be the cornerstones, driving mankind into a new life, a new job, a new environment and a new digital world, and general artificial intelligence will be the key to open the door." Hong Zhou said that Huawei suggested developing multiple intelligences of AI, developing open intelligent systems based on autonomous agents, building new computing modes, new architectures and new components, and improving the accuracy, adaptability, creativity and efficiency of general artificial intelligence from the perspective of system engineering.

Hong Zhou believes that facing the future scientific hypothesis and business vision, we need to lead new breakthroughs through science and technology more than ever before.

With a pair of iron legs and two sleeves, the heat of City Ride is beyond many people’s imagination. What is the charm that makes bicycles once again become the new favorite of leisure? Let’s talk about it today.

Some people joked that Citylide is a young person who "has no bitterness in honing his iron shovel". In fact, in addition to physical strength, riding as a leisure can really be regarded as Xian Yi for all ages.Whether it’s the central axis of Beijing or a small border town, you can have tens of thousands of cars, or you can scan the code to pick up the car. You don’t need to be a fitness expert or have too many technical thresholds. You can be in groups of three or five, and you can walk alone. Low threshold, low cost, flexibility and sociality make urban cycling a "hexagonal warrior" for fitness and leisure.

The cycling culture in China has experienced ups and downs. In 1956, a 28-inch "permanent" model was rolled off the assembly line, and New China had the ability to independently design and produce bicycles. From "Phoenix" to "Flying Pigeon", the bicycle was not only one of the "three big things" for generations of Chinese people to get married, but also connected with the mobile China in the eyes of their parents. Later, with the gradual increase in the number of motor vehicles, overpasses, expressways and bicycle lanes that are constantly being eroded have also made the space for "seeing the world at 20 kilometers per hour" smaller and smaller.

Long trapped in a cage without freedom, I finally return to the forest today. The iron shell has been sitting for a long time, and there is a traffic jam on the wide road. The bicycle culture, which changes scenery and stops at will, has once again regained its glory among young people. This time, "Is it convenient to ride a bike" is skillfully linked with the sightseeing economy and urban renewal, which has become an important consideration for traffic upgrading and landscape design in many places. In Chun ‘an, Zhejiang, the 210km cycling track is not only the "most beautiful track" of the Asian Games, but also an ideal place for citizens to relax. In Xiamen, Fujian Province, Genting Road bicycle lane with BRT connection is located on the viaduct, and it is chic and romantic to ride a two-wheeled bicycle through the clouds. Nowadays, in many places, cycling friendliness has become a new business card for cultural tourism promotion.

Embracing City Ride has not only "face" but also "lining". Riding friendship is an advanced humanistic concept and a deep development idea.According to a report by the Institute of International Transportation Organization, the return on bicycle infrastructure investment is eight times that of the former. The reason is also very simple: in car travel, the road is a tool to pass through, and when riding, the interaction between roads, shops and passing by is also the purpose of travel itself. Denser crowds, more detailed browsing and better accessibility bring more opportunities for the real economy, especially in areas that are difficult for motor vehicles to reach. Thanks to this, many casual and elegant consumption scenes are possible, and rich and vibrant neighborhoods have more room for development.

of course，The original intention of riding is no matter how good and the experience is wonderful. Without the premise of safety, nothing can be said. Uncivilized or even illegal behaviors such as red light rushing, tortuous racing, and occupying the road retrograde not only put individuals at risk, but also brought hidden dangers to urban traffic order and travel safety. If you want to enjoy riding, it is not only related to urban planning and traffic management, but also depends on the joint efforts of every cyclist.

The world is so big that you can’t finish it when you walk; The world is so fast, and occasionally I want to slow down. Therefore, when night falls, the evening breeze blows gently, and the handlebar is held for a moment, the rider can peacefully close the scenery along the way to his eyes and hold his mind in his hand.

This is exactly what it is: men, women and children have fun together and live in a single car. East, west, north and south are accessible, and two wheels see the world.

Special feature of 1905 film network　Recently, the film "Seventeen Years Old with Pain" was released. The film tells that a troubled girl who suffered from "anodynia" broke up with a gangster "boyfriend" with the help of her classmates and a new young female teacher, fell in love with the schoolmaster, escaped from her rebellious life in the past and successfully fought back. After experiencing the death of grandma, campus fire and other changes, it grew rapidly … …

Do you feel deja vu? Is it very much like a movie in the past?

Let’s take a look at the plot: a girl who is deaf in half of her ear, Li Er, wants to learn bad, and meets the unruly bad girl Li Bala. Li Er likes Xu Yi, Li Bala likes Zhang Yang, and Li Bala pursues Xu Yi at Zhang Yang’s request. Later, Li Bala died suddenly and unfortunately, Xu Yi gradually degenerated, and Li Er and Zhang Yang came together and grew rapidly … …

Lear has a crush on Xu Yi.

If you say that "Left Ear" and "Seventeen Years of Pain" are both written by Rao Xueman, the similarity is normal. Then, let’s take a look at the plot of "Looking at Heaven with Trees in Summer":

Xia Mu, a teenager, suffered from autism until Shu Yawang, a 16-year-old boy with a boyfriend, appeared to help Xia Mu get out of the haze. During her college years, Yawang was sexually assaulted by Qu Weiran, a rich second generation who fell in love with her, and Xia Mu grew up rapidly after making crazy acts in despair … …

Xia Mu rode with Shu Yawang.

The key words of the above story: illness, bad study, love triangle, crime, love in any arrangement and combination. They all have the same formula, the same taste and the same "pain" youth.

"Pain is" youth

This kind of "painful" youth film must first have a protagonist suffering from an innocuous disease, and then there will be plot conflicts due to a love triangle. Finally, due to the crime and death of some characters in the play, the life and thoughts of the protagonist will have an irreversible "arc";

They all aim at the same handsome and beautiful young actors with the same warm and soft light filters, but all of them are stiff in performance, awkward in lines, bloody in plot and rough in details. Even "Seventeen Years Old Who Will Hurt" has not been released yet, and the title of the film has been greatly vomited by netizens: "You will hurt! I have medicine! "

"seventeen years old that will hurt" caused netizens to vomit collectively.

This kind of collective ridicule is only because the "youth" they describe is a false story that is exactly the same, pale and weak, and only exists in imagination. It has nothing to do with the youth that each of us really experiences.

How did the "Pain Department" youth film come from? All this should start with the youth literature that became popular more than ten years ago.

The cover of budding magazine

At that time, the mobile phone was a non-intelligent machine that could only make phone calls and send text messages, and newspapers and magazines still occupied an important position in the media. In order to get short-term entertainment outside textbooks, campus life could only read books and magazines, so youth literature and art occupied the lives of young people.

Dumbphone

Most of the audiences of these youth novels are teenagers in their teens, who are not only ignorant of the social reality, but also ignorant of the life they are experiencing, and shallow cultural products are more likely to be accepted by them.

Youth literature similar to Mary Su’s online novels became popular at first. Later, Jing M.Guo’s and Rao Xueman’s youth literature soon surpassed Mary Su’s because of "exposing scars", "excavating the dark side of growth" and appearing "profound". When "painful youth" is gradually typed, it quickly becomes a commodity for teenagers to consume.

The cover of the most novel

The covers of these youth pain literature are all boys and girls, who "look up at the sky at a 45-degree angle, or look down at the earth with their eyebrows lowered". The sentences written on the inside page are sad and melodramatic, and they can be QQ signatures of crystal girls in minutes. The content of the story is out of line for the sake of being out of line, and it hurts for the sake of pain. In a word: work.

Look up at the sky at a 45-degree angle

"Painful youth" literature and art often adopt extreme cases in campus life in order to make their works get more amazing and more "shocking" reading experience, but the real student life is cut into pieces and simplified to the maximum in the works, and the main aspects of life become elements, while the false youth imagination becomes the main body.

Mr. Lu Xun once said that he didn’t like popular literature and art in the Republic of China, because most of the themes of those works were "beautiful and precious". Getting a few beauties and digging up any treasures are actually satisfying "psychosexuality".

Mr Lu Xun

If "getting beauty and treasure" is an adult’s fantasy, then "painful youth" is a teenager’s fantasy. It successfully captures the young people’s dissatisfaction and agitation with the boring life in reality, leaving exaggerated youth stories to the young people to "fantasize", making empty and pale characters become youth myths in the eyes of boys and girls and heroic dreams against plain life.

When did the "Pain Department" youth film begin? This should start with the release of the film directed by Zhao Weishou. In 2013, "To Youth" won a high box office of 700 million yuan at a low cost. This powerful commercial success is like a shot in the arm to stimulate the film and television industry, and the subsequent "To Youth" series came one after another and became a trend.

Box office winner "To Youth"

Although "To Youth" is full of details (for example, the "civil youth" in the film seems to live the life of a literary youth), it still maintains a certain level of plot, while the subsequent youth series generally carries forward the shortcomings of "To Youth" and has undergone major changes in creative mentality. IP and traffic stars have become the king of the market, the plot has become more absurd, and the audience has become younger and younger.

Fan movie

The environment presented by the work is more and more divorced from reality, and the setting of roles and the relationship between roles are more distorted. In order to increase the capacity of the story in a shorter time, making a movie even allows the protagonist to experience life and death in just a few days. Finally, in order to be able to mass-produce, the plot is the same. After mastering a set of winning routines for youth films, the film industry began mass production of "Pain Department" youth films.

At the beginning, three roommates of the hostess were arranged to die in a car accident

Some people may ask, are all the youth films in China like this?

The answer is no, of course. Perhaps this summer’s youth film is an anomaly in recent years. It embeds the elements of American youth film such as "club", "party", "atrix" and "inspirational" into China’s youth story, weakening the love of boys and girls to be ambiguous and ignorant, and the end result of the story is the pursuit of ideals and the realization of individual values.

"Flash Girl" composed by youth and blood

These outstanding parts may bring some inspiration to the commercial road of Chinese youth films at present.

In fact, there have been many successful youth films in China, such as Jiang Wen, Wang Xiaoshuai, etc. Among them, Sunny Days is also loved by American genius quentin tarantino.

Jiang Wen’s work Sunny Days

These excellent youth films are rooted in the background of the great era, describing the restlessness of a generation of youth, even seeing the big from the small and facing social problems directly. The rapid social changes in China over the past 100 years have made it difficult for Chinese people to have a vacuum youth that can shed social reality. Generation after generation has been involved in the torrent of the times. Even the love in adolescence has the background of the changes of the times.

Wang Xiaoshuai’s works

We criticize "painful youth", but it is paradoxical that those youth films that can be engraved in the film history are often really sad and cruel, such as Sunny Days mentioned above and Japanese director Nagisa ?shima’s youth films in the 1960s. As the Italian writer mauriac said, "Do you think youth is a good thing? Youth is like a swamp in thawing. "

In 1960, the Japanese film "The Story of Youth Cruelty"

Everyone has a different life experience and may have a different understanding of youth. For the post-80s and 90s generation, they are at the peak of birth since the founding of the People’s Republic of China, and they have experienced the cruel competition and helplessness of adult society at a carefree age.

Around the college entrance examination

They were separated from their parents by the rapid development of the times, and the two generations experienced conflict, running-in and understanding; Many of them are only children, who grew up under the love and protection of their parents, and entered the society before they were young … … Facing the unbearable weight of collision reality with the unbearable lightness of youth is the collective memory of this generation and the "pain" of youth after 80′ s and 90′ s.

An indifferent father and daughter 2.

Unfortunately, the whole theater, the stage staged absurd stories, the audience broke out with disdain laughter, and the stirring youth of a generation eventually became a commodity for people to entertain, so that the song of youth, which should be romantic and wild, was abandoned in the national entertainment.

1905 movie network news Excited heart, trembling hands. Who would have thought that a program that many netizens have been thinking about for a long time has actually come true? The entertainment circle, which has been spit out and does not leave a way out for middle-aged actresses, has gathered many female stars over the age of 30 to debut together again? ! This file began to be recorded, "Elder Sister Braving the Wind and Waves", which went up to tranquility, including Eva Huang and Claudia, and was released to Yuqi Zhang and Loura. Twenty-nine female stars lived in a big house for training, and after a round of elimination, they formed a female group to debut.

This is not sister circle 101. What else can it be? But immediately, some netizens said, do you think the audience really wants to see the girls’ group? My sister’s daily life immediately gives me 24-hour uninterrupted broadcast. They are all people who have been dreaming of the entertainment industry for many years. They know the wind and see the rain and attract the audience. Isn’t it because Malanshan Empresses in the Palace has already begun to be staged in their minds?　

Not to mention, even Liu Mintao, who let herself go and sang "Red High Heels", has been told by netizens to kick the pavilion because of various Queen’s expression packs.　

It seems that the "Sister" variety show is really different from the "Little Sister" variety show. "Pale yellow long skirts and fluffy hair" may be regarded as girls who want to enter the entertainment industry, but "sisters" want to break the circle in the audience, so do they have to "make waves"?　

If you want to get high ratings, your sister has a knife.

Although "Braving the Wind and Waves" has just started to be recorded, the inappropriate gossip has been flying all over the sky. It is said that the first day of recording was as long as 20 hours, and people began to lose their temper. No matter whether the news is true or not, netizens who have already begun to prepare for the good show have already been gearing up and waiting for how the female stars will compete with each other in the show.

Tear before sowing, regardless of the willy-nilly, make a wave of heat. This is also a routine that many "sisters" are quite familiar with. Even if you love each other in the program, you can’t wait for the female stars to have a knife in their hands and throw it at the recognized "small work" in the program for the audience.

This is probably a bad demonstration brought by the beginning of Flowers and Teenagers in 2014. It seems that only the disagreement of female stars can arouse the audience’s desire to watch.　

The English title "Divas Hit the Road" of "Flowers and Teenagers" suggests that this is definitely not a simple program. What is Diva (Network Extension means Queen)? In addition to old qualifications and good grades, the most important thing is a difficult attitude. So Diva get together, and the attraction naturally becomes the interaction between them. So in the first season of "Flowers and Teenagers", the ratings of CSM national network reached 1.14, and in the sixth episode, the ratings reached 1.29, and the ratings share became the highest in the whole season, reaching 8.33.　

In the second season of "Flowers and Teenagers", the program side obviously tasted the sweetness, and in terms of candidates, it found the tranquility known for its violent temper. The first episode broke the ratings record of last season, and it was not until the last episode that the ratings of CSM50 fell below 1.

Until now, the official announcement of "Sister Who Rides the Wind and Waves" has been made, and some people are still reviewing the second season of "Flowers and Teenagers", and analyzing the interpersonal relationship among them has become a well-known knowledge in the entertainment circle. As a result, Huang Xiaoming served as the convener and quietly participated again, which also made the audience start to look forward to the collision between "Ming Xue" and "Hua Xue".

The program is low in ratings. Sister interaction is too polite?

After tasting the sweetness brought by Flowers and Teenagers, TV stations naturally refused to give up such a variety show. After buying the copyrighted "Sister Flower", it started broadcasting in "Flowers Less", but the atmosphere was more harmonious than that of its rivals. Although Xi Meijuan, Xu Fan, Wang Lin and Lin Chi-ling and two "egg guests" Victoria Song and Andy were invited in the first season of "Sister in Flowers", the main theme of the program is the mutual care among various teams. However, in reality shows, it is indispensable for writers to use dramatic conflicts to highlight the personality of the guests and attract the audience. However, Sister in Flowers has obviously weakened the content of "sisters", and a pleasant trip can only get warm ratings.　

Compared with the first season of Flowers and Teenagers, which has kept the ratings above 1.0, the opening ratings of Sister Flower in the first season were only 0.945, and fell to 0.779 in the 12th issue. Could it be that without the sisters who "make waves", they really can’t move the program ratings?　

Idol Comes and the following two seasons, Here We Come, failed to become the same viewing monsters as Flowers and Teenagers. "Idol Comes" was invited to Brigitte Lin, and the first two episodes of the program were still ranked first in CSM50 ratings. However, since the third episode, the ratings of the program have been declining, and the ranking even dropped to the fourth.　

In this program, the legendary goddess and the popular little flowers are on the same stage, and they still take the program route of life experience, but they increase the experience rather than the interaction between members. Some people say that "Idol Comes" is not so much a variety show as an outdoor "roadshow+interview". When competitive programs such as Running Man and Extreme Challenge fill the gap of good-looking and interesting reality shows, how many viewers want to watch the polite sisters pull the plane together?　

What’s more, there are already stars who have pulled the plane. Who wants to see the same task done again? Brigitte Lin in the first season brought both ratings and embarrassment. From the moment Nana saw Brigitte Lin start to cry, the show turned into actresses being cautious in front of their idols.　

This is also the embarrassment of the current "Sister" variety show. At first, the program tasted the sweetness brought by contradictions and inner drama, but when the program wants to find a balance between meaningful and interesting, it may lose the audience that has been cultivated.　

How to take a happy life to wave when the program is transferred to the network

From "Idol Comes" and "Here We Come", variety shows are also in a period of transformation. After the third season of Flowers and Teenagers was updated in 2017, there is no new season; "Flower Sister" also stopped in 2017. At the same time, a new kind of slow variety show has appeared on TV and Internet. Dear Inn and Yearning Life premiered in 2017; The "Happy Trio" that appeared in 2018, etc., although the program format is biased towards business and life, sisters are still the mainstay of the program.

Sensing the change of the wind direction, Mango TV also launched a new "Sister" variety: "Wife’s Romantic Travel". Although it is no longer broadcast on TV, My Wife’s Romantic Travel just took the place of Flowers and Teenagers.　

Unlike "Little Flowers", The Romantic Travel of My Wife has also changed from a personal orientation to marriage and family. Wives travel, while husband-in-law groups observe from a distance in the video studio. In the second season, the broadcast volume of this program even exceeded the "Youth has You" broadcast on the same platform. Even the topic of online discussion has changed from the personality and performance of a single actress to the relationship and interaction between the actress and her husband.　

This also shows that today’s "Sister Variety" is also changing with the variety environment. After several years of cultivation of slow variety and various competitive variety, the audience has gradually changed from simply making waves to having fun from the process design and theme of the program itself.　

Is the "Sister Circle" variety show popular again? Tearing off the label can succeed.

So although it is hot on the Internet now, it is the sisters who can lose their temper and play better. However, judging from the variety shows in recent years, whether the process is good or not, whether the talents of the sisters are wonderful or not, and whether there is a stalk in personality are the key points for the final success of the program. In fact, in the last two years, the trainee series has gradually torn off the label of Sichuan style stew pork in the talent show, but it is a big breakthrough for my sisters to go to the women’s group variety show. After the announcement of "Sister Riding the Wind and Waves", the platform made a derivative variety called "Definition".

"I am afraid that I don’t have a label, and I am more afraid that I will be labeled casually; When you can’t define others, you are even more afraid that you can’t clearly define yourself. " Does this remark also mean subverting the women’s group? There is always discussion that the age limit of actresses is the glass ceiling of the entertainment circle. Netizens are always imagining that they can gather middle-aged female stars to play "The Character of a Lady".

When the actresses that everyone knows enter middle age, there are more discussions about middle-aged actresses on the Internet. Then this group of interesting and Slay (network stalk, meaning killing the audience) sisters went online collectively, did it bring new possibilities to female stars?

In many practical problems, it is often necessary to study the relationship between one interested factor and several other influencing factors. Correlation analysis only describes the strength and direction of the relationship between numerical variables, while regression analysis is a statistical method to describe more accurately how the change of one variable affects other variables through mathematical models. If you useRepresents a variable of real interest,Indicates that others may be related toRelated variables need to be established.andFunctional relationship between. hereIs called a dependent variable or a response variable, andX is called an independent variable or explanatory variable. Regression analysis is the process of establishing this relationship.
