Baojun responded to Yue brake failure, and software BUG caused brake degradation.

Recently, some car owners posted on social platforms that the brakes of the 2023 smart driving version were abnormal, which attracted the attention of netizens.

On January 4th, Baojun Automobile issued a statement in the official Weibo to respond to the relevant situation. The statement said: "This Yueye incident is not the’ brake failure’ described by the network, but the existence of some vehicles.Software BUG, resulting in the brake assist degradation. This part of the vehicle will enter the speed limit protection state when it is reminded by the indicator light when it is started. "

"After receiving relevant feedback, we intervened in the first time and solved the user’s vehicle problem. Please feel free to use it." Baojun Automobile said, "Without knowing the facts, the relevant media described the words such as’ brake failure’ as inaccurate."

Previously, many car owners reported on social media that the brakes of Baojun Yueye had failed, mainly focusing on the 2023 Baojun Yueye Flagship Edition and Zhizun Edition. The vehicle reported eps code, and the "yellow turtle" fault light appeared on the dashboard. The owner stepped down.brake pedalThe rear vehicle cannot slow down.

A car owner described the problem as follows: "When I was driving on the morning of December 31, 2024, I found that the car slipped after the car was powered on, and there was no response when I stepped on the brakes. I started the car several times without power, and the problem still existed. At the same time, the vehicle dashboard reported the EBS fault light and the drive system fault light, so I called for rescue and dragged the car to the 4s shop for maintenance. So far, the cause of the vehicle problem and the after-sales plan have not been clearly answered."

Some lesions in the annual physical examination can’t be found? Expert: Physical examination needs a "sense of design"

  Medical Guidance/Professor Wang Fangjun from the First Affiliated Hospital of Guangzhou University of Chinese Medicine

  No matter on the Internet or in real life, I can always hear people asking similar questions angrily and helplessly: one of my relatives and friends has a physical examination every year, and no problems have been found. Who knows that lung cancer has been found recently, or it is in the advanced stage! Therefore, people often ask bluntly: What is the use of physical examination? Why are some diseases still undetected? The reporter interviewed Professor Wang Fangjun from the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine.

  Text, Figure/Guangzhou Daily All-Media Reporter Weng Shuxian Correspondent Fang Ning and Zhang Qiuxia

  Don’t wait for the body to "hold on" before doing the examination.

  "Physical examination is of course useful! The use is not small! " Wang Fangjun explained that the so-called physical examination is the abbreviation of "physical examination", which is a process in which doctors use their own senses, auxiliary examination instruments and experimental equipment to collect objective information on the health of patients or normal people and conduct health assessment.

  In the past, many people went to the hospital after they felt obvious symptoms of the disease, or even "unbearable". As everyone knows, many diseases have no discomfort in the early or even the middle stage, especially cancer. When the symptoms are obvious, they often have developed to a serious stage, and the treatment effect is difficult to guarantee, even for life. Physical examination is a process in which people take the initiative to evaluate the health status of their bodies. Without waiting for the body to send out an obvious "unbearable" signal, they can find hidden dangers of diseases as early as possible and block the progress of diseases in time.

  Why didn’t the physical examination find early lesions?

  Why do you insist on physical examination every year, or are some early lesions not found in time? What do you think about this problem that puzzles many people?

  "We should be clear about the fact that the health examination of normal people is not the same as the disease examination of patients who go to the hospital to see a doctor!" Wang Fangjun said that the examination of diseases is clear-cut, targeted, accurate and meticulous, and will make a relatively accurate diagnosis of diseases in a "positioning, quantitative, qualitative and regular" manner; The physical examination is only a screening process, and we don’t know whether the body is sick or not, which is equivalent to "casting a net". Therefore, we usually only choose some simple and cheap items that can reflect important organ functions.

  If we sort out these "casting a net" health examination items, he thinks they can be roughly divided into three categories:

  1. General examination: It belongs to the most basic examination items, and usually includes blood pressure measurement, heart and lung examination, electrocardiogram examination, palpation of liver, gallbladder, spleen and lymph nodes, etc., so as to roughly judge whether there are diseases of organs such as hypertension, heart disease, lung disease and liver and gallbladder.

  2. Laboratory examination: generally including blood analysis (blood routine), urine routine, liver and kidney function, blood lipid analysis, tumor markers and thyroid function, to judge whether there are anemia, infection, hepatitis, nephritis, hyperlipidemia, tumor, leukemia and hyperthyroidism.

  3. Imaging examination: it is essential in the current physical examination, which usually includes chest X-ray photos, B-ultrasound (liver, gallbladder, spleen, kidney, thyroid, etc.) and other items.

  "Whether you apply for a medical examination on your own initiative or a medical examination organized by your work unit, you only choose a few inspection items to do." Wang Fangjun said that even "people who are not poor in money" have designed an expensive "luxury medical examination package" according to their own requirements, and in fact it is impossible to include all kinds of examination items in the hospital. Therefore, in theory, it is impossible for physical examination to "exhaust all items", and there will always be some early lesions that will be missed. Some people only check a few small items, and they are not necessarily targeted. Therefore, some early lesions have failed to be detected.

  Tips: Optimize physical examination items to improve inspection efficiency.

  So, how to improve the effect of physical examination more pertinently?

  "In fact, the physical examination is also ‘ Technical work ’ , also need to have ‘ Sense of design ’ 。” Wang Fangjun analyzed that the above-mentioned physical examination items can be regarded as the preferred basic items, and it is recommended that all the subjects can be seriously examined. In addition, some targeted projects should be optimized according to the characteristics of age, gender and occupation, so as to improve the inspection efficiency. And how to choose the best, it is suggested that we can communicate with the doctor appropriately and design the best physical examination plan with the help of the doctor.

  For example, he said that people over the age of 40 should appropriately increase items such as bladder, prostate, uterus and accessories when doing basic B-ultrasound (liver, gallbladder, spleen, kidney, thyroid, etc.) during physical examination; Women at risk of breast cancer should increase mammography and breast ultrasound; People at risk of heart disease can add items such as cardiac color Doppler ultrasound on the basis of ECG. If you are an older "smoker" or a patient with other high-risk factors of lung cancer, you should "upgrade" the chest X-ray photos to a low-dose CT examination of the chest to avoid missing the diagnosis of early lung cancer.

  If some parts of the body are obviously uncomfortable, that is to say, some symptoms or signs have appeared, then the goal of the examination is more clear. Wang Fangjun reminded that the physical examination at this time may wish to refer to the contents of "disease examination" and ask the specialist to "tailor-made" the examination items, so as not to miss the early or even middle and late lesions.

  The free physical examination at home is coming!

  Online booking service is open now.

  Guangzhou Daily News (all-media reporter Wu Shen) Is your figure healthy or invisible obesity? How about cardiopulmonary endurance, physical flexibility and balance ability? If you want to know more about your body shape, function and quality, you should pay attention to this free welfare! Guangzhou Daily’s all-media reporter learned from Guangzhou Sports Science Research Institute that from today, residents of all districts in Guangzhou can make an APPointment to receive free physical fitness tests at national physical fitness monitoring sites all over 11 districts through the mobile phone app "Grouplink", and get a deep understanding of their physical function and physical quality through the tests of 11 projects, and get a personalized "exercise prescription".

  "I have a physical examination every year. Is there any difference in this physical examination?" The importance of routine physical examination has been popular, but physical fitness test is still a new thing for most people. Experts explained that the annual routine physical examination is to check whether there is any disease in the body, and all kinds of diseases and abnormalities can be detected; The purpose of physical fitness test is to fully understand the physical condition, and to find problems at the "sub-health" stage when physical function and physical quality begin to decline, so as to prevent the occurrence of diseases.

  For people who want to lose fat and gain muscle through exercise, for example, people who want to get rid of mild fatty liver through exercise can have a physical fitness test every three months to observe the exercise effect and adjust the exercise plan in time. For the general population who usually have good exercise habits, it is also necessary to have a physical fitness test every six months to one year.

  The National Physical Fitness Monitoring Center under the Guangzhou Sports Science Research Institute conducts physical fitness monitoring for specific people every year. In order to help the public fully understand their physical condition, prevent the occurrence of diseases, provide the residents with the basis for scientific sports and improve their physical and mental health, from September 20, the function of making an APPointment for physical fitness test will be launched on the "Qunshitong" app. Residents aged 19-69 can choose the nearest national physical fitness testing site and have a free physical fitness test within the scheduled time. Through 11 items such as body composition test, bone density test, step test, vital capacity test and grip strength test, you can get comprehensive evaluation electronic report and personalized exercise suggestion, which is a good opportunity to deeply understand your body shape, body function and physical quality.

Shenzhen CDC expert: If you get A stream, you may be infected with B stream again.

  According to the report of the National Health and Wellness Commission, at present, influenza is still the main respiratory disease, and the proportion of influenza B virus in southern provinces has continued to rise in the past three weeks. What’s the difference between stream B and stream A? On January 15th, Shenzhen CDC experts interpreted it.

  According to Shenzhen CDC experts, the seasonal epidemic of influenza is mainly caused by influenza A and B viruses. There is little difference between the symptoms of influenza A and influenza B, so it is difficult to distinguish them according to the symptoms. It is still necessary to go to the hospital and cooperate with tests to diagnose them. Whether it’s A stream or B stream, their main manifestations are systemic symptoms, such as fever and muscle aches all over, while respiratory symptoms such as runny nose and cough will be lighter. Fever is persistent, and it often burns again after taking antipyretics for a few hours.

  Disease control experts believe that this epidemic season has been infected with influenza A, and it is also possible to be infected with influenza B. Influenza A and B are two different subtypes of influenza, and they do not have cross-immune mechanism. After getting influenza A or B, if the patient’s constitution is relatively weak, it is still possible to be infected with another subtype of influenza virus. Shenzhen disease control experts do not recommend that citizens use antibiotics without authorization when they have a fever, or they should follow the doctor’s advice and treat them.

  How to prevent influenza? Shenzhen CDC experts said that the influenza virus is highly contagious, and people are generally susceptible. People can get flu vaccine and do personal protection. Members of the public can be vaccinated against influenza before the start of the influenza epidemic season and at any time during the epidemic period. Free flu vaccine in Shenzhen is currently provided to primary and secondary school students and elderly people aged 60 and above (elderly people require Shenzhen household registration or purchase Shenzhen medical insurance). In addition, the public should also pay attention to personal protection such as frequent hand washing, frequent ventilation, wearing a mask, and covering your mouth and nose when coughing or sneezing to reduce the risk of infection.

Science popularization: five kinds of particles that "don’t exist" but can change the world

  Particles refer to the smallest component of matter that can exist in a free state, including electrons and neutrons. The cornerstone of modern physics — — The physical standard model is essentially a "family tree" of a particle family, and its members are familiar to everyone. The Higgs boson, which finally revealed its beauty, was sought after by scientists from all walks of life as soon as it came out.

  But there is an equally important class of particles that nobody cares about Of course, this is understandable, because these "quasi-particles" do not really exist, but their unique physical properties are enough to change modern science and technology. In a recent report, the British magazine New Scientist listed five quasi-particles that "don’t exist" but can change the face of the world.

  Phonon: electric cowboy

  In 2012, the Large Hadron Collider (LHC) at CERN discovered the Higgs boson, which is the mass source of other particles. So far, all 62 kinds of elementary particles have been discovered, and the standard model of particle physics has been perfected.

  But without phonon, all this would not have happened.

  The concept of phonon is developed in the process of studying lattice vibration. Li Baowen, director of the Center for Phononics and Thermal Energy Science of Tongji University, once explained that phonons are not real particles, but quasi-particles, which are quantized lattice vibrations. It is called a phonon because the essence of "sound" is the "vibration" of an object. In fact, the Greek word for phonon means sound.

  The name phonon was first put forward by Igor Tamm, a physicist in the former Soviet Union, in 1932. He pointed out that just as light corresponds to electrons, sound waves can be associated with some particles we call "phonons". In solids, especially in semiconductors and insulators, "heat" is conducted through lattice vibration, that is, "phonons" are carriers of heat.

  At room temperature, phonons are quasi-particles, and the heat conduction of solid materials is mainly realized by phonons. But at extremely low temperature, these quasi-particles "incarnate" into a group of "cowboys", driving away the "cattle" composed of electrons. These electrons act uniformly, and their resistance is almost zero, which is the principle of low temperature superconductivity.

  It is the huge electromagnetic field created by superconducting magnets that makes protons bend in the large circular orbit of LHC. In the magnetic resonance imaging (MRI) scanner, these superconducting magnets "transform" as a command, guiding oxygen atoms in human tissues to "dance" and releasing traceable radio signals. In addition, phonons also play an important role in the field of thermoelectric materials. These thermoelectric materials can convert thermal energy into electrical energy, and it is also expected to realize scientists’ dream of reusing waste heat from automobile engines to supply power for electronic products.

  Magneton: the king of spin

  Since Tam put forward the concept of "phonon", scientists have gradually found many such quasi-particles in solids. Another such particle originates from spin, a quantum property that is the basis of magnetism. Spin is like an arrow on an atom, pointing south or north; When all spins in matter are aligned, a magnetic field appears. However, when this spin state is constantly reversed, a wave effect is created, which scientists call "magnon".

  Ordinary computers and smart phones need electricity to store information, but the information of equipment power failure cannot be obtained. If a magnon is used, the information storage will depend entirely on the magnetic field without electricity, which is called Spintronics. The advantage of this method is that it consumes little power — — Excessive power consumption is one of the main problems encountered in miniaturization of transistor chips. If the magnetic oscillator is controlled by electromagnetic waves, the computer can completely get rid of the shackles of wires and electricity.

  Exciton: the secret weapon of plants

  The earth gets more energy from the sun in an hour than all mankind consumes in a year. Plants play the role of energy catchers, and excitons are the "secret weapons" for plants to perform this task.

  In any substance, electrons exist in different energy levels. When a photon strikes the surface of an object, it will excite electrons to a higher energy level, leaving a hole. Electrons are negatively charged and holes are positively charged. Under certain conditions, the Coulomb attraction between them will bind them together in space, so the complex formed is called excitons.

  The leaves of plants contain light-trapping proteins, and the electrons in the light-trapping proteins will be excited to absorb photons and leave their positions, leaving a hole, electrons — Excitons formed by hole pairs will float around the photosynthesis production line of plants.

  When excitons arrive at specific positions where they are needed, electrons recombine with holes and release energy, which plants use to decompose water into hydrogen and oxygen.

  This photosynthesis is the root of life on earth, and human beings have been looking forward to simulating this reaction in solar cells. In 2013, researchers at the Massachusetts Institute of Technology found a way to "photograph" excitons directly, which took a key step towards the ultimate goal.

  According to the online edition of Science magazine in 2009, Leonid Butov, a physics professor at the University of California, San Diego, and his colleagues have made several transistors based on excitons. These transistors are expected to become the basic modules of new computers, and the circuits assembled by them will become the first computing device using excitons in the world.

  Mayorana Fermion: Quantum Hero

  If you want to have a real multi-process computer, you can turn to a quantum computer for help. The quantum computer, which is still in its infancy, makes use of subtle and uncertain quantum states and can give multiple solutions to the same problem at the same time. As long as the external environment does not disturb the "magic" of the quantum computer, it can run stably.

  Majorana quasiparticles can provide "qubits" for quantum operations, which makes quantum computers more powerful.

  The information in an ordinary computer is stored in "bits", and each bit is coded as 0 or 1; Information bits in a quantum computer can exist as 0 and 1 at the same time, but this superposition state is very fragile. For this reason, physicists have been looking for ways to make qubits more stable.

  In 1930s, Italian theoretical physicist ettore majorana predicted that there must be a particle, which is the same as its antiparticle. The concept of "majorana particle" was born. It has no mass and no charge. It is its own antiparticle and always appears in pairs. Because of its special properties, majorana particles are electrically neutral and rarely interact with the environment, so it becomes an ideal carrier for quantum information coding.

  Since majorana particles always appear in pairs, which means that there are two copies of the information they contain, theoretically speaking, majorana qubits are more tolerant to external noise. However, according to Attila Geresdi of QuTech Institute in the Netherlands, these qubits exist in the background of huge electronic effects, and it is very tricky to extract the information of majorana quasiparticles.

  In June this year, the research team of Jia Jinfeng of Shanghai Jiaotong University wrote in the Physical Review Express that they had successfully captured the Mayorana fermion in the laboratory through a special artificial film composed of topological insulator materials and superconductor materials, which not only contributed to the development of quantum computers, but also helped to further uncover the mystery of dark matter.

  Wilfermion: Double-faced Jiaowa

  "Weyl fermions" are like shy "cousins" of electrons. In 1929, the German scientist H. Weyl proposed that there is a kind of electron with no "mass" and can be divided into two different "chirality" of left-handed and right-handed, and this electron is called "Wilfermion".

  The fermion has two key characteristics: massless and chiral. The lack of mass means that it can move at high speed, and at the same time, it is extremely resistant to interference that is inconsistent with its chirality, which makes it difficult to scatter: two different types of fermion streams can be close together without interaction. It has been suggested that these properties can make it the basis of computers beyond spintronics computing power.

  However, for more than 80 years, scientists have not observed the fermion in the experiment, and the semi-metallic materials with the characteristics of fermion have only recently appeared. On July 16, last year, Science magazine published the experimental results of the team of physicist Zaid Hassan of Princeton University. The team announced that they found "Waier Fermion" in "Waier Semimetal"; On July 20th, official website, Institute of Physics, Chinese Academy of Sciences, announced that the research team led by Fang Zhong, a researcher from the Institute, had successfully discovered the Verfermion in TaAs crystal for the first time. Therefore, the era of "Weyl Weyltronics" has appeared on the horizon, but there is still a long way to go.

Press conference of the State Council Office: Natural resources help build a well-off society in an all-round way

  Cctv news(News broadcast): The State Council Office held a press conference today (October 29th), and the relevant person in charge of the Ministry of Natural Resources introduced the positive contribution made by the field of natural resources to building a well-off society in an all-round way.

  According to the Ministry of Natural Resources, cultivated land is the lifeblood of grain production. According to the results of the third national land survey, we have kept the red line of 1.8 billion mu of cultivated land protection set by the state and completed the task of 1.865 billion mu of cultivated land in 2020 set by the state plan.

  At the same time, China’s geological survey has also made great progress. During the "Thirteenth Five-Year Plan" period, eight 100 million-ton oil fields, five 100 billion cubic meters of natural gas fields, five 100 billion cubic meters of shale gas fields and 311 large and medium-sized mineral fields were newly discovered. The Ministry of Natural Resources also said that in the past 10 years, China has made great achievements in ecological protection and construction, with a total net increase of 260 million mu in woodland, grassland, wetland, river surface and lakes with strong ecological functions. China has also issued institutional documents such as coastal wetland protection, grassland protection and restoration, and wetland protection and restoration, initially forming a new pattern of ecological restoration.

It takes internal strength to stabilize this bowl of mala Tang.

Tianshui is on fire! Accompanied by the red pepper running from the nose to the brain, the string of "bouquets" in hand and the boiling soup pot bottom, Tianshui attracted thousands of netizens in front of the screen to fly and take the high-speed train to come here and experience the "YOLO" for themselves.

A bowl of mala Tang makes a city with fire. The sudden explosion of fire, netizens have shouted Tianshui Wenlv: "You have to catch this wealth!" This time, the Tianshui municipal government also focused on "listening to persuasion", and started the "pet powder mode" with the actions of the whole city: painting the walls overnight, opening the Mala Tang bus line, picking up foreign tourists free of charge at airports and stations, and holding a special meeting on Mala Tang service guarantee, so as to do a good job in health protection without dead ends … The effective experience accumulated by the predecessor "online celebrity City", Tianshui people took out all the "Tao Xin Wo Zi", just to keep this hard-won. According to the data, as of March 14th, the popularity of tourism search in Tianshui increased by 186% in the past week. According to the data from Meituan and the public, from March 16th to March 17th, the advance booking volume of Tianshui’s tourism consumption (including hotels and lodging, classic tickets, transportation, etc.) increased by about 18 times year-on-year. Since the "out of the circle" of Tianshui Mala Tang, the overall order volume of Tianshui Wenlv Market has increased by 40% year-on-year.

From the smell of "Zi" last year to the feeling of "Bin" at the beginning of this year, and today’s "Mala Tang" in Tianshui, the siphon effect triggered by the cultural tourism market has made all cities deeply feel the powerful empowerment role provided by the cultural tourism industry for urban development. However, looking at these "fire out of the circle" cities, we can turn "flow" into "reserve", which is ultimately inseparable from hard work and accumulation.

As the saying goes, one side of the soil and water raises one side. The local grass, trees, bricks and tiles are condensed with rich historical background and unique customs, which can not be replaced by anyone or anything. Just as the local products Longnan pepper and Gangu pepper, which make Tianshui explode, have made this bowl of mala Tang the essence. What attracts tourists to Tianshui is not only this bowl of mala Tang, but also the lonely smoke in the desert, Maijishan Grottoes and Fuxi Nuwa’s "Poetry and Distance".

In this sense, if you want to win the initiative in regional development, you need to tap regional characteristics according to local conditions, expand service projects according to the situation, and strive to create your own "highlight moment." We should actively build a catalytic holographic service system. Through a series of explosive cultural tourism projects, we will create high-quality and cost-effective services, trigger the deepening and extension of urban awareness and recognition, and realize the promotion and optimization of multi-format services such as talents, business and investment. We should actively cultivate local characteristic brands and expand brand influence. Carefully build "time-honored brands", launch unique public brands of local products, build a modern commercial core area with "both prosperity and fireworks", and stimulate potential consumption. It is necessary to keep up with market changes, closely follow the needs of tourists, further optimize the tourism environment, scientifically formulate marketing strategies, boldly innovate marketing methods, make products more "aligned", make demand more "in place" and let "small resources" trigger "big effects".

In October, the price of "vegetable basket" declined seasonally, and the supply situation of vegetables in various places was stable and improving.

CCTV News:According to the latest data from the Ministry of Agriculture and Rural Affairs, the national "vegetable basket" index was 118.56 in October, down 2.64 points from the previous month and 11.96 points from the same period last year. Vegetable prices showed a seasonal decline.

In October, the national average wholesale price of 28 kinds of vegetables monitored by the Ministry of Agriculture and Rural Affairs was 4.86 yuan per kilogram, down 4.7% from the previous month and basically the same as the same period last year. In terms of varieties, the chain price dropped by 19 kinds and rose by 9 kinds. Among them, spinach, Chinese cabbage and lettuce have a large decline.

Zhang Jing, chief vegetable analyst of the agricultural products market analysis and early warning team of the Ministry of Agriculture and Rural Affairs:Vegetable prices have entered the seasonal downward channel. The main reasons are that since October, the main producing areas of vegetables have gradually moved southward, the scale of trans-regional transportation of northern vegetables to the south has been reduced, the storage loss in transit has decreased, and the transportation cost has been reduced; Second, the stock of durable goods is sufficient, and the supply mode conversion in summer and autumn is relatively smooth. In October, the national temperature was significantly higher than the same period of last year, which was conducive to the growth of autumn vegetables.

According to the data of the Ministry of Agriculture and Rural Affairs, the current vegetable field area in China is more than 100 million mu, an increase of more than 1% year-on-year. The output of vegetables in various places is relatively high, and the supply situation is stable and improving. Experts predict that vegetable prices will keep seasonal downward for some time in the later period, but starting from November, with the fluctuation of temperature, the growth rate of open-field vegetables will slow down, and there is limited room for vegetable prices to fall.

Zhang Jing, chief vegetable analyst of the agricultural products market analysis and early warning team of the Ministry of Agriculture and Rural Affairs:The market supply has gradually changed to autumn and winter mode, and the listing volume of protected vegetable production areas in the north has increased. As the production cost of protected vegetables is higher than that of open-field vegetables, it is expected that the downward space of vegetable prices will be limited in the later period.

The overall price of vegetables in Beijing has declined significantly in winter storage vegetables and leafy vegetables.

What is the price of vegetables in the latest market, and which varieties have changed obviously? Let’s go to the wholesale market in Beijing to have a look.

The reporter learned in Beijing Xinfadi Agricultural Products Market that recently, vegetables, potatoes and Chinese cabbage stored in winter have gradually come on the market, with a large sales volume. The market sells 1,500 tons of potatoes, 1,000 tons of Chinese cabbage, and hundreds of tons of carrots, cabbages and white radishes every day.

According to reports, due to the high price of Chinese cabbage last year, the enthusiasm of vegetable farmers was stimulated, and the temperature in the main producing areas was suitable, and the Chinese cabbage was generally harvested, which led to the continuous decline of Chinese cabbage prices in the market. In addition, the prices of fresh and tender leafy vegetables, such as rape, oil wheat and Chinese cabbage, have dropped significantly in recent years, and the prices of celery and cabbage have also dropped to the low point in the same period in recent years.

The data shows that on October 30, the weighted average price of vegetables in Beijing Xinfadi market was 2.46 yuan per kilogram, down 2% compared with last week.

Tong Wei, head of Beijing Xinfadi Market:The origin of vegetables in the later period is mainly in Hebei and Shandong, and the supply is relatively sufficient. In the future, prices will continue to run at a level lower than that of the same period last year.

How did the short video kill your time?

18 years is a year of short video explosion, and many users will have a feeling that they can’t stop when watching short videos. So how exactly did short videos kill your time?

If 2016 is the outlet of live broadcast and bike-sharing, 2017 is the outbreak period of short video. Time has entered 18 years, and the popularity of short videos has become more and more prosperous.

The familiar short video players: Tik Tok, Watermelon Video, Volcano Video and Aauto Quicker are among the top ten in the industry.

I believe that every user who watches short videos has had this feeling: I just watch two … and then slip away in half an hour. How did the short video, known as the "time killer", kill your time and make it disappear unconsciously?

In this regard, individuals have the following ideas:

Since the outbreak of mobile internet, recommendation system is not a new word. Providing users with his favorite content is what recommendation system is good at! For example, today’s headline machine recommendation information flow, Netease Cloud Music’s magical song list recommendation … It will make you have a dedicated service experience, so that users can’t stop using the APP.

Combined with the psychological flow effect, we can see the magic more clearly.

Flow: In psychology, it is a kind of psychological state when you concentrate on a certain behavior, and entering this state will make people feel happy.

When you are immersed in the glory of the king qualifying, when you are still reluctant to leave the TV screen at one or two in the morning, you are in a flow.

In this state, you don’t want to be disturbed, that is, you resist interruption. It’s like you will keep starting games and watch TV series episode after episode, as if you can’t control yourself. In fact, your brain doesn’t want to control yourself to stop.

Combining the two, the recommendation system pushes your favorite content and updates it constantly. You don’t want to stop sliding your finger when you enter the flow state. In the short video of 15s, you unconsciously brush it until 2 o’clock in the middle of the night …

With the development of technology, information is carried from words to pictures, to videos, and then to live broadcasts. You will find that:The improvement of information carrying mode has a subtle influence on your brain.

Although words, pictures and videos can explain the facts, but:

  • The form of words will bring people more imagination space after extension. After words enter the brain, it will take some time to be translated to understand (although it may only take a few seconds).
  • Compared with words, pictures are a more intuitive expression method, which objectively shows the facts in a shorter time, but as a static display, there is still some room for imagination;
  • Video and live broadcast are one step closer. What you see is what you get. The imagination space is further compressed, the content of objective expression is enriched, and the human brain can directly receive more information, which can be understood without the second translation of the brain.

The live broadcast was a hit in 2016, and I personally understand that this has the same reason. As a recorded video, the live broadcast form gives people a more intuitive feeling of time and space, but the live broadcast also has a short board because of real-time, and users are not free all the time. If you miss the time, it will lose its meaning.

With the increasing fragmentation time of users, short videos have become the best channel for users to enjoy themselves. Short-term entertainment, easy-to-understand content, this experience will make the brain addicted and easier to immerse itself in.

Personally, this situation can be explained by a law in Thinking, Fast and Slow:

Rule of Least Effort: If there are many ways to achieve the same goal, people will often choose the simplest one.

After carefully studying the development, content tendency and product function of Tik Tok, it is found that its popular mode fits well with the addiction model mentioned in the book Addiction:

Tik Tok’s brand promotion, the forwarding and dissemination of wonderful short video content in social software, and the first stage of the addiction model cycle: trigger comes into play.

For whatever reason, when you click on the link to play, you have entered the second step of the addiction model cycle: action. Next, you will see all kinds of dazzling content.

The difference between the addiction model and the common feedback loop lies in that it can directly stimulate people’s strong desire for something, Tik Tok’s precise control in the content direction, and challenging the variability of gameplay, so that every time you slide, you can bring new surprise variables, and the brain excitement will continue to rise because of unexpected rewards, expecting to find more surprises.

In the last stage: input, not only means making users willing to spend money, but also means that users’ behavior can improve the subsequent service quality. Praise, attention, etc. are all the inputs paid by users to improve the product experience.

These inputs will have an impact on the first three stages. Triggers are easier to form, actions are easier to take place, and rewards will be more attractive.

Judging from the current analysis, short video, as a sharp weapon to kill time, seems to have stepped on the breakthrough points of two times: the development of technology and the outbreak of information. At the same time, the psychological nature of human beings since ancient times has been infinitely magnified by various means in this era. Is the outbreak of short videos really just accidental? I do not think this is necessarily the case.

At present, I have only analyzed the environmental and industrial factors, but not the in-depth product experience analysis. I believe that each product has its unique attraction to users, which is also a direction that I will study in depth in the future.

The above are some of my personal superficial ideas, and I hope to communicate with you.
