  High incidence in summer!

  Be wary of children suffering from herpetic angina!

  After entering the summer, children’s herpetic angina has entered a trend of concentrated high incidence. Xi ‘an Children’s Hospital receives more than 500 children with herpetic angina and hand, foot and mouth every day.

Many people have been infected in Xi 'an! Be alert, it's high recently!

  Zhang Huifang, deputy chief physician of the fever clinic of Xi ‘an Children’s Hospital, said that the main harm of herpetic angina is easy to cause febrile convulsions and viral encephalitis. Children may be prone to dehydration, shock and other clinical symptoms due to sore throat and reduced food intake.

  Zhang Huifang, deputy chief physician of the fever clinic of Xi ‘an Children’s Hospital, reminds parents that to prevent herpetic angina, they should keep their children’s hands and mouth clean, avoid going to crowded places, and seek medical advice in time if they have high fever.

  A 4-year-old boy in Hangzhou suddenly had a high fever of 40℃

  Febrile drugs don’t work either.

  Not long ago, 4-year-old Nannan suddenly had a high fever, and her body temperature went straight to 40 degrees. The heat peak reached 3 or 4 times a day. Even if she took antipyretics, she could not drop to normal temperature.

  After going to the hospital, the attending doctor made a careful physical examination and found that Nannan had a lot of herpes in his mouth, which hurt when he touched it, and there were red rashes in other parts of his body. According to the typical rash manifestations and the location of the rash, the doctor judged that Nan Nan was infected with hand, foot and mouth disease.

  Brother and sister suddenly convulsed

  Confirmed hand, foot and mouth disease

  At 1 am on June 15th, a 1-year-old boy, Yue Yue (pseudonym), was taken into the pediatric emergency room of Changsha Central Hospital (Changsha Central Hospital affiliated to Nanhua University) by his mother Li Ru (pseudonym) and was diagnosed with hand, foot and mouth disease. At 3 pm on the same day, my 3-year-old sister MengMeng (a pseudonym) was also admitted to the hospital due to convulsions, and was also diagnosed with hand, foot and mouth disease.

  Herpes angina & how to prevent hand, foot and mouth

  What are the performances?

  Hand, foot and mouth disease: fever, maculopapules and herpes of hands and feet, herpes or ulcer of oral mucosa (herpes is more common in the front of oral cavity, such as tongue and lips and teeth), pain and difficulty in eating.

  1-2 months after the onset, some children will have finger/toenail shedding.

  Herpetic angina: fever, sore throat, mucosal herpes in pharyngeal isthmus and superficial ulcer.

  Relationship between hand, foot and mouth disease and herpetic angina?

  They are all caused by a variety of enterovirus infections, and many enteroviruses can cause both diseases at the same time, such as the red virus in the picture below.

Many people have been infected in Xi 'an! Be alert, it's high recently!

  After being infected with the same virus, if herpes is only in the throat, it is herpetic angina, and if it appears in the hands, feet, mouth and anus, it is hand, foot and mouth disease.

  The study found that the blood routine of hand, foot and mouth disease or herpetic angina indicated that white blood cells increased, the proportion of neutrophils increased, and sometimes CRP(C-reactive protein) increased, which was not necessarily accompanied by bacterial infection, so parents should not blindly use antibiotics.
.

  How did it spread?

  Droplets in digestive tract or respiratory tract spread and contact with herpes fluid of patients’ skin and mucosa, which is highly contagious and fast.

  How to prevent it?

  Vaccinate hand, foot and mouth vaccine (although it can only prevent EV71, most severe hand, foot and mouth diseases are caused by EV71), wash hands frequently and pay attention to hygiene.

  Ventilation frequently, avoid going to public places where crowds gather and air circulation is poor during the epidemic period, and see a doctor in time when symptoms appear.

  People with hand, foot and mouth disease should avoid contact with other children.

Li Xikang: Leading High Pollution Paper-making Villages to the Road of Green Development

CCTV News:Huangchong Village in Dongguan, Guangdong Province is located at the intersection of Dongjiang River, its tributaries and Zengjiang River. From the air, there are many peasant apartments, fashionable holiday hotels, grand industrial parks and lush trees, which not only presents a beautiful and exquisite Lingnan water town, but also a happy and prosperous paradise.

But no one would have thought that the leading industry in beautiful countryside was the paper industry with high pollution. In recent years, the village environment is getting better and better, the collective economy is growing, and the villagers’ pockets are getting bigger and bigger, all of which are inseparable from the "head of the family" in the village — — Li Xikang, secretary of the village Party Working Committee and director of the village committee.

Li Xikang is a native of Huangyong. He graduated from high school in the early 1980s and was one of the few cultural people in the village at that time. At that time, he wanted to work hard outside, but considering that the construction in the village was in its infancy, it was time for knowledgeable young people to return to work in the village, so he went to work in the village-run cement factory.

one

Five years later, due to his outstanding ability, Li Xikang was promoted to the director of the cement plant, and joined the team of the village party branch in 1997. At the same time, he also served as the chairman of the village-run enterprises Yinzhou Paper and jinzhou area Paper. In July 2005, Li Xikang took over as the general branch secretary of the village party.

When he was first appointed secretary of the General Party Branch, the paper industry in Huangyong Village was in urgent need of transformation and upgrading because of its high energy consumption and low productivity. In order to make the management of village-run enterprises change their minds, he organized everyone to visit advanced paper enterprises at home and abroad and hired experts to demonstrate, and finally the transformation and upgrading plan was passed by unanimous vote. Now, Huangyong Village has become the representative of high-end paper industry. Last year, the village collective disposable income exceeded 580 million yuan.

For more than 10 years, Huangyong has persistently promoted industrial transformation and upgrading, which has made Huangyong paper industry always play a decisive role in Guangdong paper industry. Now, Huangyong Village has become the representative of high-end paper industry. The environmental protection investment of the three paper enterprises in the village each exceeded 100 million yuan. In 2017, the village collective disposable income exceeded 580 million yuan. "In those days, I took party member cadres to do mass ideological work every day, and I didn’t sleep well. Although it is very hard, all the efforts are worth it. "

The village is rich and should benefit the villagers. Under the leadership of Li Xikang, Huangyong Village has implemented a series of measures to improve people’s livelihood, including building affordable peasant apartments and helping villagers in need to repair old houses and dangerous houses or demolish old ones to build new ones; Promote villagers’ employment and entrepreneurship, and establish "medical assistance for major diseases" and "grants for children from difficult families".

Li Dehui, a villager in Huangyong Village, Zhongtang Town, said: "If you earn money, you still care about the villagers. The whole village has excellent sanitation, public security and environment, just like a small town. Some villagers are seriously ill and have subsidies for you and lend them to you. This secretary and the masses have a good impression of him. "

When talking about the enthusiastic help given by Secretary Xikang, the villager Xie Huangui also burst into tears. In March, 2005, Xie Huangui was just 17 years old, and was in Grade One. He was diagnosed with uremia, which put the ordinary family in trouble. With the care of Li Xikang and the help of the village Committee, Xie Huangui’s condition improved day by day. In 2011, Xie Huangui got married and became pregnant with a child.

"When our family was at a loss, the village committee lent a helping hand again and again. My body recovers day by day, my daughter goes to kindergarten, my husband has a job, and my family lives happily. I really appreciate the village Committee and Secretary Xikang. " Xie Huangui said.

Li Xikang insists on bringing the fruits of economic development to the people and has always been committed to doing a good job in people’s livelihood. "Serving the people is the foundation of doing a good job in rural work. This is not an empty check, but everything should be people-oriented and realize the joint construction and sharing of the whole people." 

With deep feelings, he devoted himself to the development of Huangyong village by implementing various effective measures, so that the people could get more employment, their income increased steadily and enjoy more development achievements. Li Xikang is leading Huangyong Village to a road of beautiful countryside construction with the beauty of development, life, ecology and humanity, and has opened a new picture of the most beautiful countryside.

It is cost-effective! BYD Song Pro fuel version, absolutely 100,000 SUV.

In fact, as early as the debut of Song Pro, Tako began to pay attention to and be optimistic about this new car, and its strength in all aspects was quite good. On the whole, the only uncertainty is the price without losing any "popularity TOP" in the same class; As for the fuel version of Song Pro, my prediction and expectation at that time was: as long as the final quotation of the top model can be controlled within 130,000 yuan (the top quotation of the Haval H6 is 136,000 yuan), you will be the most beautiful child in the same class in 2019!

Now the official guide price of Song Pro fuel version is 898-119,800 yuan, which is 10,000 yuan lower than my expected psychological price of 130,000 yuan! That is to say, compared with the old and popular models at the same level, Song Pro has a price advantage of at least 15,000 yuan (equivalent to 12%), and it has occupied a cost-effective highland as soon as it debuted. In this way, in the compact camp of 100,000 yuan, the competitiveness of Song Pro is definitely a lever drop ~ Let’s talk about it in detail.

The cool appearance is unique

Song Pro’s debut is unforgettable. Its net is like a dragon with an open mouth and ready to devour everything. It has a strong sense of momentum, and this full sense of beast is amazing to Tako: the original front face can be so beautiful when it is fierce! Later, I learned that this unique front face has a unique name-Dragon Face, and Song Pro is the first model to adopt Dragon Face2.0 design language.

When I saw Song Pro, who would have thought that BYD’s face value was one of the biggest slots of this brand a few years ago ~ At that time, it was a straight man of steel in appearance, and he was powerless: he really couldn’t eat by his face, and he didn’t fight hard. What should I do?

But with the joining of Wolfgang Egger, the former Audi design director, he finally began to "dare to kill"! Tang He is Wolfgang Egger’s quite successful work, and Song Pro is a beautiful answer sheet of prosperous times that he is no longer shackled by the old design style.

Wolfgang Egger may have been infected by the "lamp factory" and began to ponder the headlights after he arrived. Although Song Pro is not as serious in lighting as that, it still plays the lighting beautifully and the overall shape is just right. For example, the "Dragon Beam" headlights with dragon claws add a lot of brilliance to the whole vehicle. What is even more amazing is that the three claw marks light up step by step when it is turned on, which is full of ritual sense, which is very satisfying the little fun of wanting to be handsome.

In fact, everyone’s evaluation of the appearance is subjective after all, and there is no uniform standard. It cannot be said who has a stronger sense of design and who has a higher value. However, I prefer Song Pro’s "Dragon" myself. After all, compared with competing products like Haval H6 and Changan CS75 at the same level, Song Pro is really more fresh, more fashionable in style, and handsome people are heart-pounding!

One in a million interior materials.

Before tasting the interior of Song Pro, I want to talk about its size. The length, width and height of Song Pro are 4650mm*1860mm*1700mm, respectively. Compared with Song PRO, in addition to maintaining the same height, the values of length and width have improved, especially reaching an astonishing 2712mm, which is 56mm higher than Song PRO. The multiple increase in size brings an all-round breakthrough in the internal space. When you open and sit in the cockpit, a big man who is more than 1.8 meters can stretch his body, which is a great advantage in the compact class. Although Tako himself is average in height, he will have long legs someday, don’t you think? The rear seats are more comfortable to upgrade. The maximum 100 11-gear segment can be adjusted, and the length of 510mm supports the legs. Even if five seats are full, you can have a slight rest.

In fact, everyone’s evaluation of the appearance is subjective after all, and there is no uniform standard. It cannot be said who has a stronger sense of design and who has a higher value. However, I prefer Song Pro’s "Dragon" myself. After all, compared with competing products at the same level and Changan CS75, Song Pro is really more fresh and fashionable, and handsome people are heart-pounding!

The wide internal space gives Song Pro great room to play, for example, the golden compartment has five seats. "Golden compartment" is reflected in the design difference between the front and rear seats. In the front row of the extrasensory intelligent driver’s seat, the center console is tilted 7 to the driver’s side, reaching the most reasonable application angle, supplemented by the embracing interior design, giving the driver a full sense of control-sitting in the driver’s seat seems to be in the center of the world, taking care of the driver’s emotional needs. Few cars have noticed this before, and Pro seized this pain point first.

On the whole, the interior style of Song Pro is relatively atmospheric and quiet, and it may not be so lively and fashionable in sense, but it creates a strong sense of grade and artistry. The most conspicuous is the central control area. When the physical buttons are relocated to the gear area, there is no button left in the central control area. This minimalist postmodern style (I think it is) may not be to everyone’s taste, but I personally really like it.

The 12.8-inch central control panel is actually a suspended pad, which can be placed horizontally or vertically; The DiLink system can be said to be one of the most advanced systems at the same level, which refreshes Tako’s view on the car-as long as you sit in the car, you can completely replace the mobile phone. The intelligent voice system, which accommodates 4 million+applications worldwide and can recognize 8 dialects, is highly entertaining. More smart driving functions will not be described here, and interested friends can go to the test drive experience.

Accurate driving control, comfortable and free.

First of all, the power configuration of Song Pro fuel version: equipped with 1.5T, model BYD476ZQB, 118kW, 245N·m;; Matching 6-speed DCT, it has three driving modes: economy, comfort and sports, and the whole system automatically shifts gears.

The dynamic performance of Song Pro is slightly improved, and it is definitely worthy of the current pricing. Take the top version of competing products (the official guide price is 133,800 yuan) as a comparison. The sum is the same as that of Song Pro, but the torque is 20N·m higher and 13kW higher. This premium space is open to different people.

Song Pro’s driving style is biased towards home commuting, which is a very relaxing model. The new car as a whole has achieved the ultimate in terms of driving, which can be clearly felt. No matter whether it is low speed or acceleration, it rarely encounters setbacks, and the shift is also very smooth. This kind of performance is far beyond Tako’s expectation, and it is quite different from the traditional impression, which is an unexpected surprise.

As mentioned above, Song Pro has three driving modes, and the power feedback corresponding to different driving modes can be understood literally. In the economic mode, the rotation speed will be kept relatively low and the power output will be slightly soft; Switch to sports mode, the speed increases, the acceleration is immediately fed back, and the speed-up performance is better; And the comfort mode is in between. Each of the three modes has its own advantages. After being familiar with the control, it can be switched according to different driving scenarios, which is both easy to use and fuel-efficient, which is also in line with the label of Song Pro’s "cost-effective model".

Generally speaking, Song Pro has a very good performance in terms of design, space interior and power control. Let’s not talk about the appearance and the value of the interior. Those configurations that can fall on paper to the battle are better than those of Song Pro at the same price. Compared with the same configuration, Song Pro is cheaper, and the price is really not lost. It’s hard not to love ——Tako. Isn’t this a "tap water" for Pro ~

In the first half of the year, the consumer goods industry as a whole showed a trend of stabilization and recovery, and the consumer market gradually recovered.

CCTV News:The State Council Information Office held a press conference yesterday (July 19th). A spokesman for the Ministry of Industry and Information Technology said that in the first half of this year, with the in-depth implementation of the policy of expanding domestic demand and promoting consumption, the domestic consumption scene gradually recovered, the logistics level quickly rebounded, and the consumer market was gradually recovering.

Tao Qing, spokesperson of the Ministry of Industry and Information Technology and director of the Operation Monitoring Coordination Bureau:In the first half of the year, the consumer goods industry as a whole showed a trend of stabilization and recovery, and the output of electric bicycles, refrigerators, air conditioners and other products increased by double digits.

Tao Qing said that the Ministry of Industry and Information Technology will release and implement the work plan for the steady growth of light industry in the near future, focus on stabilizing key industries such as household products, plastic products, leather and food, fully stimulate the potential of domestic demand, actively promote export advantages, upgrade the modernization level of industrial chain, and accelerate transformation and upgrading, quality improvement and efficiency improvement. At the same time, we will continue to carry out production scheduling of key medical materials such as vaccines and drugs to ensure the normalized demand for materials. Accelerate the construction of centralized production bases for small-variety drugs, monitor the production and supply of short drugs, and ensure the orderly and stable supply of the market.

I can’t hear after catching a cold. The problem is not the ear, but the nose.

  "Doctor, doctor, I caught a cold and got angry a few days ago. My nose is stuffy and my throat hurts. But now I have recovered from my cold. Why do my ears always feel stuffy? Is it water in my ears? Could you please help me get it out? I can’t get it out myself … …”

  The above situation is often encountered by otolaryngologists in outpatient clinics. In fact, most of this situation is secretory otitis media, which is very common in our otolaryngology department. The most common causes are poor drainage of eustachian tube and upper respiratory tract infection.

  So, what is the eustachian tube? Eustachian tube is a channel connecting our ears and nasopharynx. It is normally closed, and it only opens when we open our mouths, swallow, yawn and sing, so as to keep the pressure balance inside and outside the middle ear and tympanic membrane.

  However, when we catch a cold and catch fire and get an upper respiratory infection, bacteria and viruses can also infect the middle ear from the nasopharynx and oropharynx through the eustachian tube, leading to our middle ear infection, commonly known as "otitis media". Patients with otitis media caused by upper respiratory tract infection generally have no ear pus, and most of them show a feeling of stuffy ears, accompanied by a slight decline in hearing. But it generally does not cause severe hearing loss.

  Patients sometimes feel that their hearing loss is not obvious, and they may only find it when they answer the phone with their left and right ears and feel that the sound is different. When you go to the hospital, the doctor will ask you about his medical history. Some patients may be complicated with allergic rhinitis, and they have been used to allergic rhinitis for many years, so they don’t think there is something wrong with their noses.

  In fact, only when patients control nasal diseases such as allergic rhinitis well, nasal ventilation will be better, and the effusion in the middle ear will slowly improve. Like a kitchen sewer, only when the sewer is open can the water on it flow down. The inflammation of our nose and throat is controlled, and the eustachian tube is unobstructed, so that the effusion in the middle ear can be slowly absorbed or drained through the eustachian tube and discharged through the pharynx.

  By giving the above patient an otoscope examination, it was found that his eardrum was intact, his external auditory canal was clean and there was no bath water. On the contrary, you can see that there is water in the eardrum through the eardrum. After more than a week of conservative treatment with nasal spray and oral mucus-promoting agent, the hearing of the patient has improved obviously and basically returned to normal level.

  Therefore, if we have sudden hearing loss after catching a cold, we should seek medical advice as soon as possible. Because the earlier the diagnosis and treatment, the easier it is to cure, and generally oral nasal spray hormone combined with mucus excretion promoter can be used. If it is delayed for a long time, the effusion will become thicker and thicker like egg white, which will easily form "glue ears", and the treatment effect will be poor, which may also affect hearing in the future.

How to judge the quality of rough houses? What are the misunderstandings in this judgment method?

As a common choice in the new housing market, the quality of rough houses directly affects the subsequent decoration and living experience. Judging the quality of rough houses is a job that requires professional knowledge and experience, but many people are easy to fall into some misunderstandings in the judgment process.

The quality of rough houses can be judged from many aspects. First of all, the appearance of the building, observe whether there are cracks and falls off the facade. If there are cracks in the facade, it may mean that there are problems in the building structure, and water seepage may occur in subsequent use, which will affect the durability and safety of the house. The second is to check the doors and windows to see if the doors and windows can be opened and closed properly. If the doors and windows are not tightly closed, it will lead to poor sound insulation and heat insulation, and there may be problems such as air leakage and rain leakage. In addition, the flatness of the wall surface, with tools such as ruler to detect whether the wall surface is flat or not. The uneven wall surface will bring difficulties to the subsequent decoration and increase the decoration cost. In addition, the water and electricity lines are also very important. Check whether the water pipes are leaking and the circuits are unblocked. Leakage of water pipes will lead to damp inside the house and damage the decoration materials, and the circuit will affect the normal life electricity consumption.

However, there are some common misunderstandings in judging the quality of rough houses. Many people think that it is normal to have small cracks on the wall, but it is not. Some small cracks may be the initial manifestations of wall settlement or structural problems. If we don’t pay attention to them, they may gradually expand over time and affect the safety of houses. Some people think that the waterproofing of rough houses will be fine when they are handed over. In fact, the waterproofing test at the time of delivery may only be short-term. In the subsequent decoration process, if the construction is improper, it may still destroy the waterproof layer and lead to water leakage. In addition, some people rely too much on the brand and reputation of developers, and think that the quality of the houses of big brand developers must be no problem. Although big brand developers usually have a stricter quality control system, the possibility of quality problems in individual projects cannot be completely ruled out.

In order to show the judgment methods and misunderstandings more clearly, the following table is used for comparison:

Judgment method Misunderstanding performance Observe the appearance of the building and check the cracks and falls off of the facade. Ignore small cracks and think that it will not affect the use. Check the door and window switch and tightness. Think that the switch is smooth and there is no problem, and don’t pay attention to sealing. Detecting the flatness of the wall surface. I feel that the unevenness in a small area does not affect the decoration. Check the water and electricity lines When the test is normal, you will no longer pay attention to the subsequent hidden dangers.

To judge the quality of rough houses, we need to check all aspects comprehensively and carefully, and at the same time, we should avoid falling into common judgment misunderstandings to ensure the purchase of houses with reliable quality.

Helping people practice embroidery and prospering the city with micro-renewal

There is an animal that has four legs when it was a child, two legs when it grows up and three legs when it grows old. Many people have guessed this riddle, and the answer is people.

Babbling is protected by parents and supported by children when stumbling. This is the inheritance of a complete Chinese family. Children don’t have to worry about speeding cars when they play downstairs, and the old people feel meticulous care when they move indoors. This is the temperature transmitted to residents by a friendly city.

Shanghai, a prosperous international metropolis, has not only the colorful side of high-rise buildings, but also the winding alleys and noisy streets. In addition to pursuing an open, inclusive and dynamic urban temperament, it has become the pursuit of Shanghai’s new round of urban development planning to see Excellence in detail and replace demolition and construction with transformation, and to outline the space that is livable, suitable for raising and suitable for business with embroidery needles in the context of urban history. In order to protect the style of historical blocks, more and more old communities in Shanghai have begun to be slightly updated from the bottom up, and the government, enterprises and residents have participated in the co-construction and carried out temperature transformation.

In 2018, Shanghai Vanke, together with Xinhua Street and famous designers in Changning District, held the theme forum of "2018 Urban Design Festival | Beautiful Xinhua", focusing on the micro-renovation of public and residential spaces. As the chief co-builder, Shanghai Vanke mainly participated in the urban micro-renewal project of Xinhua Road Street at three points, covering many aspects such as the transformation of public spaces in streets, communities and corridors. Nowadays, the old community has taken on a new look, and the micro-renewal has brought a great sense of gain to the local residents.

Guarding the "sunset" 70-year-old house "transformation"

Grasping the newly-installed handrail on the wall with both hands, 90-year-old Guan Apo climbed the stairs step by step, slowly but steadily. For her, she has lived here for most of her life, and the bricks and tiles of the surrounding buildings and apartments are so familiar, so fresh and warm, such as this aging-adapted staircase.

Guan Apo’s apartment is located in a 70-year-old public house called Jinglaocun. As the name suggests, there are 19 elderly people living in the house, three of whom need to travel in wheelchairs. Jinglaocun used to be a three-storey dormitory building of state-owned enterprises. Like many similar buildings in Shanghai, there were many "problems" before the renovation, such as insufficient lighting, messy corridors, dense pipelines and lack of barrier-free facilities.

Respect for the elderly village before transformation

In November 2018, Jinglaocun began to transform. Shanghai Vanke and designers collected opinions and suggestions from residents in the building extensively, and finally decided to start from two parts: functional perfection and spatial integration, and create a more humanized, functional and modern living space that meets the needs of the elderly on the basis of preserving the historical features of the old building as much as possible.

When the old building got a new look, Guan Apo lost sleep: "I feel almost unrecognizable, and I stayed up happily that night."

Residents all believe that "the changes in the old building are earth-shaking." However, for designers, the overall structure of Jinglao Village has not been adjusted, and only three treatments have been made: increasing the light source at the top to enhance the aisle lighting; Walls and columns are wrapped with materials to make the corridor cleaner and more unified; Increase storage and functional space, and enhance the practicality of public space.

Considering that the residents are all elderly people, a large number of arc design elements are adopted in this renovation to avoid the coldness of hard lines visually and narrow the distance between buildings and people; Corners, stairs, lockers and other areas use rounded corners to minimize the possibility of bumping; The house number is specially enlarged and equipped with lighting facilities to solve the problem of unclear identification of the elderly and facilitate identification.

In the corridor, groups of lines with different colors on the ground are particularly eye-catching, extending all the way along the corridor. Shanghai Vanke said that these lines enhance the modernity of the building and also have a guiding function. It turns out that considering that some old people have bad waist and legs, and even some old people have a serious hunchback, the designer specially printed a "guide line". As long as he remembers the line corresponding to his own door, he can go home along the line without any difficulty.

There are still many such intimate designs in respect for the elderly. For example, there is a hidden compartment on one side of the stairs. With a gentle push, a stool will come out and you can sit on it and rest your feet. Beside the aisle, there is also a climbing grid tailored for pets.

People often say that the older people get, the smaller their hearts get. Old people need colorful and energetic lives. After the transformation, the village for the elderly uses a lot of bright colors, the first floor is vibrant yellow, the second floor is quiet blue, and the third floor is peaceful and green. People are in it, and there is no sense of boredom at all.

The reformed respect for the elderly village

What makes many residents around envy is that the elderly who respect the old village have their own sunshine garden. "Sit down and have a chat in the sun", in the corner of the roof of Jinglaocun, these words are particularly conspicuous on the ground. Bright yellow sofas and white umbrellas are arranged here as a leisure area for old people to chat about their homes and see the scenery. The original roof of Jinglao Village had a large idle area, so the designer re-planned it and set up a rest area, an activity area, a planting area and a drying area, so that the old people really had their own social space.

"China has entered an aging society, and the number of elderly people is increasing by 10 million every year. We hope to make their lives better and safer through warm design. " Zhang Haiao, an architect who participated in the design and renovation of Jinglao Village, said.

Take care of "Chaoyang" and make "parting ways" for hundreds of miles.

Wu Xin, a young designer who lives in Lane 222, Panyu Road, has a deep understanding of this sentence. Every day, she will walk here with a stroller-the ground is uneven, and the veranda, flower beds and vehicles will separate the 100-meter-long lane.

After the reconstruction of Lane 222 of Panyu Road

When thinking about the renovation plan, as a designer, Wu Xin considers enhancing the mobility of the pedestrian road; As a mother, she wants to create a safe and harmonious activity space for the next generation. After extensively soliciting opinions through activities such as "residents’ brainstorming", Wu Xin finally put forward the concept of "walking laboratory" from the perspective of a child, and drew lessons from the idea of sharing corridors in cities such as new york. Based on the two principles of "walking first" and "child-friendly", he designed to cancel kerbs and height differences, providing a complete shared corridor for pedestrians, non-motor vehicles and low-speed motor vehicles.

In the process of implementation, Shanghai Vanke divided the pavement into three sections with different colors, signs and enclosures: the middle garage area was painted with wave curves, which were taken from the history of the local "Niuqiaobang", and the fresh powder painting could play a warning role for passing vehicles; The original messy flower stands were demolished in the pedestrian areas on both sides, and a child-friendly walking experimental belt was made by using the free space, with four different colors to give pedestrians different walking experiences, and a simple children’s play area was designed with the help of various graphics. Through a series of transformations, the originally chaotic alley has been transformed into a shared passage giving priority to pedestrian and slow walking, especially providing children with a safe, free and comfortable walking experience.

A staff member of Xinhua Road Sub-district Office said that this transformation not only changed the street appearance, but also brought new ideas to urban design and management. "Urban renewal is immersive and integrated, and residents can participate together."

In addition to hardware, urban renewal projects also need post-operation and maintenance. In order to let more residents participate, the reconstruction team held many activities in this lane, such as a beautiful community festival and a community drama workshop, so that people can more integrate into community management.

Strolling along the Rainbow Road, you can see children jumping out of houses, old women with gray hair pacing, and young people with skateboards taking a nap on benches … This is the most charming and authentic alley style.

According to Shanghai Vanke, Panyu Road 222 will be widened into a two-way traffic lane in the future. The reason why they are willing to spend their mind and money is that they hope to explore the possibility of "sharing streets" through this "walking laboratory" and find the perfect combination of history, culture and modern life.

Expansion of Linked Emotional Micro-space

Sharing is not only for maximizing the use of resources, but also for emotional exchange and sharing. Some time ago, the TV series "Everything’s Fine" was a hit in China. Su Daqiang, the protagonist in the drama, was cheated out of his pension money because of his high income. He was almost cheated out of his real estate by a nanny because of emotional emptiness, and he did ridiculous things because of selfishness, weakness and stubbornness. In essence, this is an important reason why a person’s temperament has changed greatly due to his lack of family care and effective social interaction.

The study found that the more frequently the elderly socialize, the higher the happiness index. Experts from the Institute of Epidemiology and Health Care of University College London investigated the social situation and health status of 6,500 British men and women over 52 years old. The results show that compared with those who have a normal social life, the risk of death of socially isolated people is 26% higher.

In this round of urban micro-renewal, the third project of Shanghai Vanke has locked in the social problems of the elderly.

Xinfeng Village, located in Lane 669 of Xinhua Road, is a community with a relatively high proportion of elderly people, with half of the people over 60 years old. Old people love to be lively and chat, and neighbors often talk for an afternoon. However, Xinfeng Village has no special space for chatting. The public telephone kiosks and canteens with a net width of less than 1.1 meters at the entrance of the gate are the assembly points, and the space is narrow and the air is difficult to circulate.

Before the transformation of "good neighbor" micro-space

"It is necessary to provide residents with a space that can stay safely, be open and friendly, and reshape neighborhood relations." With this original intention, the designer and Shanghai Vanke transformed this small space into a micro-space in the name of "good neighborhood". In order to expand the space swing area, the gate of the community has been moved by one meter as a whole to ensure that residents outside the glass door do not scrape with vehicles. The "Neighbourhood" micro-space is also equipped with wooden benches and bookshelves, and sitting in it to chat at home and talk about mountains has become an important part of residents’ daily life.

Soon after the opening of the "good neighbor" micro-space, people’s behavior deeply touched the reformers. "The original bookshelves were empty, and now there are more and more books, which are spontaneously brought and shared by residents; There used to be an old doll on the table, but now it has become a lively’ old exchange corner’; The message board on the wall also wrote many wishes of the residents … These actions have brought everyone closer. " A staff member of Shanghai Vanke said.

The reformed "Good Neighborhood" Micro-space

"Neighborhood" micro-space has become an inseparable social place in the community, and other supporting facilities have also changed. The sorting garbage bins in the community are handled by foreign designers. Apart from telling people how to distinguish the types of garbage through colors, he also set up an independent tool room, with a washbasin, a locker, clothes hangers and high-pressure water pipes for cleaning arranged in an orderly manner, so that cleaning workers can also feel the deep warmth.

Bottom-up community micro-renewal stimulates urban power

"Although it is only some micro-updates, we hope to bring real changes to the lives of residents." Shanghai Vanke designer Zheng Wei said.

This change has been going on, and Vanke is also actively exploring in the field of urban renewal. In Shanghai, Zhangjiang Guochuang Center changed from an old LCD factory to a science and technology center; Shangsheng New Institute has changed from the former Shanghai Institute of Biological Products into a "7×24" vibrant community … Through a series of transformation, the idle stock assets have been given new functions.

Shanghai Vanke has also participated in the renovation of several old residential quarters such as Sanjia Garden and Yangqu Residential Quarter. It is worth mentioning that the micro-renovation projects of the three residential quarters that it participated in in in 2018 are all located around Shangsheng Xinsuo. In the future, this vibrant community will integrate office, entertainment, life and cultural functions, and radiate the surrounding areas, forming a series connection between urban organic renewal and the improvement of residents’ quality of life. Zhang Hai, senior vice president of Vanke Group and CEO of Shanghai Regional Headquarters, expressed the hope that through a series of transformations, young people will have room for struggle, residents will share the fruits of urban renewal, and the historical context will be passed down and the characteristics of the district will be brought into play.

The reporter learned that in the new round of urban development in Shanghai, a large number of urban renewal projects have emerged with the aim of exploring the urban context, preserving historical features and revitalizing existing assets. On this basis, the urban micro-renewal project with the community as the main transformation object is becoming an important component of this force. Taking Changning District as an example, in 2017, the "Two-year Action Plan for Beautiful Blocks" was launched, focusing on building four demonstration blocks, namely Xinhua Road, Yuyuan Road, Wuyi Road and Panyu Road (fahuazhen road). It was clearly stated in 26 construction tasks in eight categories that "urban renewal should be taken as the starting point to comprehensively improve the landscape effect of block buildings". Yuan Xiangqing, director of the regional function development office of Hongqiao and Zhongshan Park in Changning District, said: "Small-scale and gradual urban micro-renewal provides a new development path in the future. By increasing the functional space of blocks and communities, we will create a slow and comfortable functional experience, increase public greening, and improve the living environment, thus changing the lifestyle and improving the quality of living. " He said that more and more urban renewal people began to pay attention to streets and communities. As can be seen from the existing community micro-renewal projects, social capital participation is very high. This urban renewal model, which is guided by the government and participated by the public, has created a lot of vivid and interesting urban stories.

Hou Zhiren, a professor of landscape architecture at the University of Washington, said that in the past half century, there have been many bottom-up non-profit organizations in urban renewal in the United States. They not only restore old buildings, but also provide employment opportunities for community residents and opportunities for commercial development, and play a very important role in urban development. "(Urban renewal) can start with community creation and explore resources that have not been seen before. Some of these resources are physical, and some are human and cultural, which can turn decay into magic. "

Create2024 Baidu AI Developer Conference: 1 basic model series and 3 AI development tools to help everyone be a developer.

On April 16th, Baidu held the Create 2024 Baidu AI Developer Conference. Many guests including Li Yanhong, founder, chairman and CEO of Baidu, gave speeches on the stage and shared the latest technological progress of Baidu in the AI field with developers all over the world.

Everyone is a developer.

Li Yanhong, founder, chairman and CEO of Baidu, delivered a speech on the topic of "Everyone is a developer", which brought a powerful basic model series and three AI development tools to developers around the world, and formed a toolbox to support developers to pack and take away. Li Yanhong said that in the future, natural language will become a new general programming language. As long as you can speak, you can become a developer and change the world with your creativity.

Powerful basic model series, that is, Wenxin big model series, include: flagship versions of ERNIE3.5 and 4.0, and lightweight versions of ERNIE Speed, Lite, Tiny, etc. At the scene, Li Yanhong also officially released the tool version of Wenxin Big Model 4.0. Since ERNIE Bot was released more than a year ago, the number of users has exceeded 200 million. At present, Wenxin Big Model has become the most advanced and widely used AI basic model in China.

Three "out-of-the-box" AI development tools, including AgentBuilder, AI native application development tool AppBuilder, and ModelBuilder of various sizes. Li Yanhong said, "Today, you can make an AI application without writing code; You can make an agent without programming. "

In terms of specific ideas for developing AI native applications, Li Yanhong pointed out that MoE, small model and agent are three directions worthy of attention. "This is what Baidu has paid for by stepping on countless pits and paying high tuition fees according to the practice of the past year."

Speaking of open source and closed source, Li Yanhong emphasized, "Everyone used to think that open source is cheap. In fact, in the big model scenario, open source is the most expensive. So the open source model will become more and more backward. "

In addition to developing tools, Li Yanhong also brought financial and resource support to developers. At the conference site, Li Yanhong announced that the second "Wenxin Cup" Entrepreneurship Competition was officially launched, recruiting entrepreneurial innovation teams in the direction of AI native application for global markets and college students, and setting up a "special award". He said, "Particularly excellent projects will have the opportunity to get 50 million yuan in cash and resources support."

New progress of Wenxin big model: agent, code and multi-model

Wang Haifeng, chief technology officer of Baidu, gave a speech on the topic of "Building the Foundation with Technology, Brilliant Milky Way", and interpreted the key technologies and latest progress of many large-scale models of Wenxin, such as agent, code and multi-model. Wang Haifeng said that agent is an important development direction, which will bring more applications. Based on the basic model, the agent further carries out thinking enhancement training, including supervised fine tuning of thinking process, preference learning of behavior decision-making, and enhanced learning of result reflection, and then gets the thinking model. The thinking model of an agent, like a human being, can read the instructions, learn how to use tools, and then call tools to complete tasks.

From the trillion-dollar training data, Wenxin Big Model not only learned the ability of natural language, but also learned the ability of code, and opened up the process from thinking to execution. Based on these two capabilities of Wenxin Big Model, Baidu developed a code agent and an intelligent code assistant. Wang Haifeng said: "The code agent allows everyone to do what only programmers can do before, and everyone can become a programmer; Intelligent code assistants help professional programmers to write better code more efficiently, which can be said to be programmers’ AI peers. "

Wang Haifeng also shared the multi-model technology. He said that the effect, efficiency and cost are very important in the process of large-scale model application. In practical application, it is necessary to choose the most suitable model from the needs of the scene. On the one hand, it is efficient and low-cost model production; On the other hand, it is multi-model reasoning.

The sustained and rapid evolution of Wenxin model benefits from Baidu’s full-stack layout of chips, frameworks, models and applications, especially the joint optimization of the flying paddle deep learning platform and Wenxin. The weekly average training efficiency of Wenxin Big Model reached 98.8%, which was 5.1 times higher than that when it was released by ERNIE Bot a year ago, and the reasoning efficiency was 105 times. Up to now, Flying Paddle Wenxin Ecology has gathered 12.95 million developers, served 244,000 enterprises and institutions, and created 895,000 models based on Flying Paddle and Wenxin.

Released by Baidu AI Cloud

Wanyuan, a New Generation Intelligent Computing Operating System

Shen Yao, executive vice president of Baidu Group and president of Baidu AI Cloud Business Group, officially released Wanyuan, a new generation of intelligent computing operating system. By abstracting and encapsulating the intelligent computing platform in the AI native era, it shielded the complexity of cloud native system and heterogeneous computing power for users and improved the efficiency and experience of AI native application development.

Shen Shayi said that with the continuous evolution of large-scale model technology, programming through natural language is becoming a reality. Programming will no longer be process-oriented or object-oriented, but demand-oriented; The process of programming will become a process for developers to express their wishes and bring revolutionary changes to the operating system. In the kernel of the operating system, the underlying hardware has changed from CPU-based computing power to GPU-based computing power, and the world knowledge compressed by large models has been added. The object of operating system management has undergone essential changes, from managing processes and micro-services to managing intelligence.

"The traditional cloud computing system is still important, but it is no longer the protagonist. We need a brand-new operating system to abstract and encapsulate the new computing platform, that is, intelligent computing, and redefine human-computer interaction to provide developers with a simpler and smoother development experience." Shen Yao said.

All along, Baidu and Intel have maintained close cooperation in infrastructure, providing customers with mature solutions in the cloud, edge and end. Chen Baoli, vice president of Intel Data Center and Artificial Intelligence Group and general manager of China, said that AI is one of the core strategies of Intel’s development, and the company is currently integrating AI into its overall product portfolio. Baidu is one of Intel’s important partners. In the original era of AI, we look forward to the cooperation between Baidu and Intel, which will bring the positive impact of intelligent computing to thousands of industries.

Agent: Creating the Original Future of AI

He Junjie, senior vice president of Baidu Group and general manager of Baidu Mobile Ecological Business Group, delivered a keynote speech on "Agent: Creating the Original Future of AI". He Junjie said that agents will reshape the way people interact with technology and bring new application ecology, traffic pattern and business model. Baidu mobile ecology is not only a hot spot for the growth of large-scale model applications, but also the head of the wave of agents. No matter users, customers or ecological partners, they can share the low-threshold, multi-scenario and high-value agent ecology in Baidu Mobile Ecology.

He Junjie said that at the user level, Baidu Mobile Ecology is committed to creating a "super agent available to everyone". He showed the new progress of Baidu New Library and ERNIE Bot APP on the spot; At the customer level, business agents, smart broadcast stars, etc. are becoming the standard and infrastructure of commercial operations; On the ecological level, AgentBuilder is committed to making everyone an agent developer and a platform that everyone can develop, operate and benefit.

In addition, Baidu ecological platforms such as Baidu search, maps, and post bars can also access the capabilities of agents, allowing developers to obtain real traffic support.

"agent ecology is not a’ one-man show’ of big players, but a’ chorus’ of the whole people." He Junjie said that Baidu Mobile Ecology always adheres to the principle of "making applications, building capabilities and building ecology", so that every ordinary person can become a developer and every developer can become a creator. Baidu welcomes all enterprises, developers and ecological partners to jointly seize the new opportunities brought by agents and open up the next golden age of traffic.

A small launch of the world’s first AI native operating system DuerOS X.

Super brain was officially launched.

Li Ying, vice president of Baidu Group and CEO of Xiaodu Technology, officially released DuerOS X, a new generation operating system, which is the world’s first AI native operating system based on Baidu Wenxin model. Li Ying said: "As an important and large-scale landing scene of the model, the degree of AI intelligence helps lead the AI native application to a new height." Different from the past, as the world’s first AI native operating system, DuerOS X has completely subverted the old model of the traditional "human adaptation system" and truly achieved end-to-end "connecting users’ intentions and tasks". This innovation has greatly expanded the boundaries of the operating system.

At the Create AI conference, Li Yanhong, founder, chairman and CEO of Baidu, interacted with Xiaodian Tian AI tablet robot equipped with DuerOS X. Through several rounds of dialogue, Xiaodi can not only clearly arrange complex schedules, but also express his language more vividly. Not only is it smarter, more capable and more understanding of users, but it can also provide users with emotional companionship value, and it will truly become a more useful and soulful AI partner that everyone can have.

2024, as the first year of AI native application, the launch of DuerOS X is not only a small-scale extreme brain change, but also a subversive innovative application of the big model. In the future, Xiaodi will bring more people a convenient, comfortable and technological life experience through continuous exploration and breaking the ceiling of intelligent ability, improve people’s quality of life, and truly let AI enter thousands of industries and thousands of households.

"AI is setting off a creative revolution. Developing applications in the future is as simple as shooting a short video. Everyone is a developer and everyone is a creator." Li Yanhong said. Just as the theme of Baidu World 2023 is "Creating the Future", at the end of the speech, Li Yanhong said that today, everyone can become a developer, and the future will certainly be a future created by developers together.

Comparative analysis of the operation of three major cross-border e-commerce platforms, analysis of cross-border e-commerce platforms at home and abroad

Comparative analysis of the operation of three major cross-border e-commerce platforms, analysis of cross-border e-commerce platforms at home and abroad

At present, there are representative cross-border e-commerce platforms such as AliExpress, eBay, Amazon, JD.COM Global Buy and so on, and there are countless cross-border e-commerce websites around the world. Below, we will make a simple analysis of the three mainstream cross-border e-commerce websites.

First, Amazon

Amazon Amazon is the highest-selling and most profitable cross-border e-commerce website in the world, firmly occupying the mid-to-high-end market of cross-border e-commerce. It has sites in every developed country, including the United States, Canada, Mexico, France, Germany, Britain, Italy, Spain, Japan, China, India and Australia.

Advantages:

1. There are few sellers, many buyers and low competition. There are 3 million global sellers and 400 million active users, covering 65 countries.

2. Amazon, the global shopping platform, has the highest average customer price, with the average customer price exceeding $17 and high profit.

3. Logistics advantage, Amazon dedicated logistics, the world’s 123 major operation centers will distribute goods to 185 countries and regions around the world.

4. Amazon’s traffic is relatively large, and there are many global sites, which is suitable for taking a refined route.

Disadvantages:

1. Due to the fierce competition in Amazon, more and more merchants have settled in Amazon, which leads to the need for new sellers to spend a lot of money on product evaluation and advertising, which requires a certain amount of funds.

2. Amazon needs to use FBA for distribution, and it can also get a shopping cart. It means that you need to stock up, which is risky. Once there is a problem, or the product selection is incorrect, you may lose it.

3. Amazon’s review is strict, and the control of goods is strict.

Second, AliExpress

AliExpress (English name: AliExpress) was officially launched in April 2010. It is the only online trading platform built by Alibaba for the global market and is called "international Taobao" by the majority of sellers. Its main market is Russia, and it is the first cross-border e-commerce platform with local traffic.

Advantages:

1. Alibaba’s platform has a large traffic.

2. The platform is mainly aimed at Russia, Brazil, Turkey and Eastern Europe.

3. The operation is similar to Taobao.

Disadvantages:

1. The ranking is not guaranteed, and Ali advertising needs to burn a lot of money.

2. The gold content of customers is not high, and the unit price of customers is low.

3. The settlement cost is high.

Third, eBay

EBay is an online auction and shopping website that allows people all over the world to buy and sell goods online. Ebay was founded in San Jose, California on September 4th, 1995 by Pierre Omidyar under the name of Auctionweb. People can sell goods online on ebay.

Advantages:

1. Relatively fair ranking and professional customer service support;

2. New sellers can be exposed by auction;

3. The threshold for opening a store is relatively low, but the rules are cumbersome and need to be studied.

Disadvantages:

1. The buyer’s protection policy is strong, and most of them are biased towards the buyer when they encounter sales disputes, and the seller suffers heavy losses;

2. The English interface is unfriendly and it is not easy to get started;

3. The cost is not low, the store is free, and the products on the shelves need to be charged.

4. Strict seller standards (for goods such as fake goods), and stores will be closed in case of complaints;

5. paypal is generally used for payment, which has certain risks;

6. The review period is long, and it can only be auctioned. There is a starting limit on the number of products. It is necessary to accumulate credibility to sell more and more, and the billing period is long, which needs to be accumulated slowly.

Be alert! It only takes 67 seconds to make a fake chat record.

  Open the software, set the avatar and nickname, and you can create WeChat conversations, transfer records and even screenshots of friends — — In online search engines and mobile app stores, chat record generation tools such as "WeChat conversation generator" and "QQ conversation generator" spread wildly. These confusing gadgets are not only used by Wechat business to deceive consumers, but also provide convenience for criminals to forge screenshots to manipulate public opinion.

  Experts said that making false screenshots will cause trouble on the Internet and disrupt social order, and those with serious circumstances will face criminal punishment. Software publishers who fail to remain neutral and encourage, abet and add fuel to the flames in the process of dissemination will also be regarded as accomplices and bear corresponding legal responsibilities.

  Case: False screenshots spread rumors

  A few days ago, Weibo, a child suspected of being sexually assaulted in an orphanage in Guizhou, detonated the network, arousing public anger.

  According to the poster, in Bijie, Kaili and other places in Guizhou Province, young children in welfare homes and kindergartens for left-behind children were sexually assaulted. However, Guizhou public security investigation found that the so-called photos of "underage children being sexually assaulted" spread on the Internet were all forged after the poster collected them from the Internet, and the whole incident was fabricated.

  Why does an unfounded rumor convince many netizens? This is inseparable from the poster’s fictional WeChat chat record. In the screenshot, a chatterbox said that it is "a business" to spend 100,000 yuan on this matter every year. Another screenshot shows that the suspected "windmill kindergarten" staff member "Chen Likun" and another person are talking about injecting hormones into young children.

  As a result, the detailed and realistic chat record has become a "sharp weapon" for spreading rumors.

  "There are avatars and transfer records on it, and even the WiFi signal is clearly displayed, exactly the same as my WeChat page!" After the rumor incident in Guizhou was officially rumored, some netizens pointed out that the chat record generation tool condoned evil and confused people. "Who would have thought that even chat records could be faked?"

  After searching for public information, the reporter found that the use of forged screenshots of chat records to spread online rumors and manipulate public opinion has occurred many times before. Screenshots of chat records with "pictures and truth" have captured the curiosity of many netizens and the herd mentality of "believing in it or not", which has become one of the carriers of online rumors.

  Test: A record is released in 67 seconds.

  Compared with the uproar caused by using fake dialogue records to create rumors, the low cost of fraud is unimaginable. As long as it takes 67 seconds and 90 yuan money, you can make a fake record exactly like the online rumor.

  Although the official has warned that the screenshot record is not credible in multiple channels, both Apple and Android platforms can find a large number of apps with the function of "chat record generation". After downloading one of the "Dialogue Generator" softwares, the reporter found that it can make multiple functional pages such as WeChat chat, group chat, transfer, change, red envelope, video chat, circle of friends and so on, and can also make Alipay transfer records.

  Subsequently, the reporter took a fake screen shot that was popular on the Internet as an example, and uploaded five conversation records, a photo and the heads of both sides of the conversation. It took only 67 seconds from setting the avatar and creating the nickname to the final fake screenshot of WeChat.

  In addition to the fake text and picture dialogue, even the system prompts such as sending and receiving red envelopes and adding friends can be faked, and even a fake screen shot of transferring 100 million yuan a day can be made under the condition that the real WeChat transfer limit is 200,000 yuan a day. Some software can also edit the operator, WiFi signal, battery power, time and other information in the mobile phone status bar at will.

  An Internet source said that there were a lot of such tools around 2015. At the beginning, most users were Wechat business, marketing number, etc., and most of them were free software. However, the reporter found that these apps are basically charging now, forming a "gray industry" with unclear legal definition at present. For example, in the dialogue generator, the page generated by the reporter has a watermark, and only those who pay for the package can remove the watermark and make the screenshot "more real". The cheapest package is 3-month 90 yuan, and the permanent membership package is 328 yuan, which will be used until 2029.

  So, how much are these apps used? Take the existing apps in APPle App Store as an example. The most popular "Wechat business Screenshot King" software has as many as 11,000 ratings and comments, and the least is 1,760.

  Wechat business Xiaoai, who runs a "private cake" in a circle of friends, told reporters that she had exposed many fake screenshots. "When I first opened the business, no one bought it. I made a few screenshots of transferring money and praising the delicious cake every three to five times, which was quite attractive." Xiao Ai said that it is the "convention" of Wechat business industry to attract customers with false records.

  Vigilance: encouraging crime to bear legal responsibility

  "The illegal behaviors caused by forging screenshots of chat records can be mainly divided into two categories." Hu Gang, Deputy Secretary-General of the Legal Work Committee of internet society of china, said that one kind is for business purposes, for example, Wechat business made false chat and transfer records and sent them to friends for advertising. "This behavior is suspected of false propaganda, which not only violates consumers’ right to know, but also disrupts fair market order."

  Hu Gang said that what is more serious is the behavior of individual criminals who forge screenshots of chat records to create topics on the Internet, stir up trouble and disrupt social order in order to gain attention or vent their feelings.

  "In the past, people always said that seeing is believing, so the majority of netizens were less alert to the rumors of chat recording. But with the current information technology, even dynamic video fraud is easy. " Hu Gang said that once public opinion is used, it may have serious consequences. This requires relevant departments to launch effective new measures in a timely manner, and also requires netizens to raise their awareness of vigilance and not be credulous or blindly obedient.

  In addition, although this kind of software claims that it is only used by netizens for entertainment, you can clearly see some leading words such as "Wechat business must have" and "Wechat business marketing tool" on the software promotion page. "This means that it has entered the category of network gray production." In the opinion of experts, if a software publisher can’t maintain enough neutrality, but encourages, abets and fuels illegal activities in the process of communication, it will be regarded as an accomplice and bear corresponding legal responsibilities.
