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.

China Wisdom and China Program

General Secretary of the Supreme Leader put forward in his important speech on July 26th that "China’s development has reached a new historical starting point and Socialism with Chinese characteristics has entered a new stage of development". We should strive to achieve socialist modernization, that is, the second century goal, after winning the decisive battle to build a well-off society in an all-round way. China has gone from poverty to poverty, from everything to prosperity, to entering and building a well-off society in an all-round way, and to modernization. The changes in China have attracted worldwide attention. Although we still have many problems to solve, every Chinese has a deep sense of gain.

Does China’s experience mean anything to the world? I think it is meaningful, especially for developing countries. As General Secretary of the Supreme Leader pointed out in his important speech on "July 26th", "Socialism with Chinese characteristics has expanded the way for developing countries to modernize, contributed China wisdom and provided China’s plan for solving human problems". China is the largest developing country in the world, and the road of China is different from that of the west. In the past, the west always vilified and even slandered us, saying that we were autocratic and that we had no freedom, human rights and so on. Facts speak plainer than words. Isn’t the significance of China’s experience and China’s road obvious to developing countries?

I remember there was a sensational news on the Internet last year that a Shanghai girl responded to the color revolution. One of her teachers in the United States asked her, why don’t you have a color revolution with so many young people in China? She found two pictures of Pudong in Shanghai for her teacher, what Pudong was like in the past and what Pudong is like now. She said, why should we make any color revolution to change it when we are living so well? This China girl has Chinese’s self-confidence. What self-confidence is there? It is our road confidence, theoretical confidence, institutional confidence and cultural confidence. Others have to consider: in such a poor country, great changes have taken place in such a short time, and the people are so confident. Is this road useful to us? Therefore, the concept of China Road is a great inspiration to developing countries. Specifically, there are at least several aspects:

First, China has both long-term planning and concrete measures to implement the planning in its development. This is a great inspiration to some developing countries, because many developing countries and even western developed countries lack long-term planning. A politician in a western country said that we are all politicians, but politicians in China can make long-term plans, but we can’t. It’s useless for us to make them. Politicians in China can do things for the people, and we consider running for office every day, so we can’t do practical things. Planning and doing things are our advantages, doesn’t this inspire developing countries? Therefore, one of the most important connotations of China Road is that there are both long-term plans and concrete measures to implement these plans.

Second, develop the socialist market economy. Other developing countries have also developed market economy, which is not as successful as ours, and some even developed into polarization in the end. Why? Because China combined the invisible hand with the visible hand. The invisible hand is the market, and the visible hand is the macro-control of the government. If we just engage in a laissez-faire market economy without considering the adjustment of supply and demand in the market, it is likely that resources will be wasted a lot, and in the end, all products will be surplus, which will not be enjoyed by ordinary people and the economy will still be in a state of collapse. What we have is a market economy system under the macro-control of the state, which is called socialist market economy. Many developing countries are considering this experience, that is to say, we can’t simply engage in a laissez-faire market economy, but we must also have macro-control by the government.

Third, not only enliven the rich, but also help the poor out of poverty. At the beginning, our poverty alleviation was to help the poor in rural areas and the low-income people in cities. Later, we engaged in development-oriented poverty alleviation so that the poor could master skills and really get rid of poverty. Since the 18th National Congress, General Secretary of the Supreme Leader has put forward a big project: precision poverty alleviation. Millions of team members went to villages and households to register their cards, find out the base number and solve the poverty problem. Recently, the General Secretary of the Supreme Leader proposed to help the poor in depth and use some new measures to solve the problem of poverty alleviation for the deeply poor. We have announced that by 2020, when a well-off society is built in an all-round way, the rural poor will be lifted out of poverty according to the current standards, all poverty-stricken counties in the country will be stripped of their hats, and the problem of regional poverty will be solved well. Invigorating and getting rich and helping the poor out of poverty are the fundamental purposes of our party to serve the people. Although there is still a gap between ordinary people, it will not lead to polarization and confrontation. The United Nations has also affirmed China’s great contribution to achieving its Millennium poverty reduction goal, which is also very enlightening to developed countries.

Fourth, reform, development and stability are organically unified. Reform is the driving force and development is the goal. Develop in reform and be stable at the same time. We are soberly aware that there are many contradictions in a developing country. If the society is unstable or even the political situation is unstable, all reform measures will not be implemented and all development goals will be ruined. Many countries develop Western-style democracy and freedom, with unstable society and political situation. All development is empty talk, and all reforms cannot be promoted. The Communist Party of China (CPC) combines reform, development and stability, and organically unifies the strength of reform, the speed of development and the affordability of the people. This experience is unparalleled in the world. Some people make irresponsible remarks about our stability, and have no idea why we can succeed or the characteristics of China society. The organic unity of reform, development, stability is a great highlight of China road.

Fifth, combine electoral democracy with deliberative democracy. Our choice of democratic system is not to engage in the western election system, but to combine the two forms of electoral democracy and deliberative democracy. By exercising the right to vote, ordinary people can choose their favorite leading cadres who can lead the rich, have the spirit of reform and innovation, and are law-abiding, honest and clean. More importantly, we also have a consultation system. No matter who is a cadre, we must go through consultation before making major decisions. Our consultations include political parties, big consultations, government consultations, CPPCC consultations, people’s organizations consultations, grassroots social consultations, and social organizations consultations. The whole democratic system is different from the West. General Secretary of the Supreme Leader said that the democracy that people were awakened when they voted was formalism. Our democracy is that you vote when you vote and continue to participate in democracy after you vote. Our major decisions seek the opinions of the people, which is not available in western developed and developing countries.

Therefore, China Road, China Wisdom and China Plan are of great significance to developing countries. What Chinese did was written in two histories, the first was written in the history of the great rejuvenation of the Chinese nation, and the second was written in the history of the progress of the people of the world. We must have this spirit, and we can also have this spirit; We have this pursuit, and we can achieve it.

Breathing through your mouth will make you "stupid and ugly"! Measure how you breathe.

  Editor’s note:"Good health is the capital of revolution", but in busy life, people are often busy with work and eager to socialize, but they ignore the geomantic treasure of good health. In fact, with a little attention and early prevention, health is around us. People’s Health Network launched the column "Know early and know early" to collect and sort out the health knowledge that you usually ignore, be your health think tank, and carry out health with you to the end!

  Breathing through your mouth will make you "stupid"

  Breathing with your mouth open doesn’t mean that you can breathe in more oxygen. On the contrary, it will affect your breathing because of the wrong way of breathing, which will oppress your nose and leave your brain in a state of hypoxia. If the oxygen intake is not enough, the quality of sleep will be poor, people will easily doze off during the day, lose concentration, and even their intelligence will be slightly affected.

  Especially for children under the age of 14 who are in the period of growth and development, their physical development and the development of the nervous system and brain will be affected. If they miss the critical development opportunity, their memory will be reduced, their thinking will be inattentive, their reaction will be slow, and they may gradually become "stupid".

  As long as children are found to be breathing through their mouths when they are sleeping, watching TV and staring blankly, parents must pay attention. One more thing, children sleep very noisily at night, tossing and turning, and even snoring, which is also a danger signal. Parents must take their children to see a doctor in time to find out what causes them to breathe through their mouths.

  Do you breathe through your mouth when you sleep?

  How to judge how you breathe? The Japanese Physical Maintenance Association wrote an article introducing the common manifestations of patients with oral respiration. Everyone can test themselves, which is more consistent, and some adjustments should be made during sleep.

  When unconscious, the mouth is half open; Dry lips; When I wake up in the morning, my throat hurts burning; Unable to consciously move the nostrils; Relax and look in the mirror, and the corners of your mouth are always downward; Make a slurping sound when eating; Snoring; The thickness difference between upper and lower lips is large; The lower lip "covers the sky"; Irregular or protruding teeth; Used to chewing with unilateral teeth.

  Compared with nasal breathing, oral breathers have seven adverse consequences: the virus directly enters the mouth without passing through the nasal cavity, and they prefer to catch a cold; Easy to dry in the mouth, less saliva and heavy bad breath; There is little saliva containing bactericidal ingredients, and I like to grow worm teeth; Pressing the throat during sleep, easy to snore, poor sleep quality; Hinder the growth and development of teenagers’ chins, and make the teeth arranged unevenly; Affect facial muscles and bones, making the face crooked; The sense of smell is the oldest sensory nerve, which is directly connected with the brain. Without air passing through the nasal cavity, the olfactory function of the brain will be dulled.

  Patients can try to adjust their sleeping posture instead of lying on their backs; Don’t be too tired when exercising, choose the intensity that can make you gasp without opening your mouth; When sleeping, you can put special tape on your mouth.

  Mouth breathing may "destroy the face value"

  Mouth breathing has a great influence on a person’s face, which can’t be ignored, especially during the growth and development of teenagers’ faces.

  First of all, there are two main reasons for mouth breathing: one is that the upper respiratory tract is blocked, and sinusitis, nasal polyps, turbinate hypertrophy, adenoid hypertrophy, tonsil hypertrophy, etc. cause respiratory tract blockage, so that you can’t breathe through your nose, but you can only breathe through your mouth; In another case, there is no disease, which is simply caused by bad habits.

  If infected in childhood, the adenoids become swollen and inflamed, which may cause permanent hypertrophy of the adenoids. Adenoid hypertrophy will hinder nose breathing and affect the excretion of sinus, which is easy to suffer from sinusitis. Tonsils and adenoids are enlarged in childhood, reaching the peak at the age of 6 to 8, but with the increase of age, their volume will gradually shrink and generally degenerate at the age of 12.

  If teenagers have some diseases of nasal cavity or adenoid tonsil, it will lead to poor nasal ventilation and then oral breathing. Mouth breathing has changed people’s original way of breathing, which makes the nasal cavity unable to ventilate normally and causes abnormal development. If the nasal cavity can’t breathe normally, people can only open their mouths to breathe, which will change the normal position of oral tissues. Changes in the position of lips and tongue will cause changes in teeth and maxilla. When breathing with the mouth open, the strength of buccal muscles on the dental arch will easily lead to the narrowing of the dental arch and abnormal tongue position, and the strength of buccal muscles on the maxillary dental arch will be strengthened, and the maxillary dental arch will gradually become narrow, and the upper teeth will lean forward, eventually forming buck teeth.

  Raise your lungs and do more breathing exercises in autumn and winter.

  Autumn and winter are the periods of high incidence of respiratory diseases, including colds, acute bronchitis, acute attack of chronic bronchitis and pneumonia. Breathing exercises can improve the symptoms of chest tightness, shortness of breath, dyspnea and wheezing in patients with respiratory diseases, realize the adjustment and entry of breath in the body, improve the function of human viscera, and thus improve the immunity of the body. Clinical research shows that breathing exercises can obviously restore lung function.

  There are seven sections of breathing exercises, and the specific methods are as follows:

  Lip contraction breathing

  Objective: To prevent the small airway from trapping and narrowing during exhalation, so as to facilitate the discharge of air in alveoli.

  Methods: Inhale with the nose, close your lips lightly when exhale, and exhale slowly, with your mouth whistling.

  abdominal respiration

  Objective: To enhance diaphragm strength, reduce airway resistance, increase tidal volume, and improve hypoxia and carbon dioxide retention.

  Methods: Put your right hand on your belly button and your left hand on your chest. When inhaling, expand the abdomen outward to the maximum extent and keep the chest still. When exhaling, contract the abdomen inward as much as possible and keep the chest still.

  Hold one’s breath

  Objective: To prolong the exchange time of oxygen and carbon dioxide in lung and make more oxygen enter the blood.

  Methods: Inhale, hold your breath for 3 seconds, turn your head to the right and exhale. Inhale, hold your breath for 3 seconds, turn your head to the left and exhale.

  Stretch breathing

  Objective: To increase lung function and relieve shoulder and neck pain.

  Methods: straighten your arms, raise your head forward and upward gradually, and inhale deeply at the same time; Then put your arms together, lean forward and exhale deeply. (Note: Try to breathe by abdomen. )

  Press and knead to welcome incense.

  Objective: To relieve rhinitis, toothache and cold.

  Methods: Flex the thumb with both hands and massage Yingxiang point with the first knuckle (Yingxiang point is opened next to the midpoint of the outer edge of the nose, which is in the nasolabial groove).

  Push the wind pool

  Objective: To relieve headache, neck ache and stiff neck.

  Methods: With the palm of your hand spread out, push the ipsilateral posterior occipital Fengchi point with the side of the little finger joint or thenar respectively (Fengchi point is parallel to the earlobe on both sides of the major tendon behind the head and forehead), commonly known as pushing the major tendon to achieve a sense of pain.

  Chest percussion

  Objective: With the help of the vibration and gravity produced by tapping, the secretions stranded in the airway can be discharged.

  Methods: The fingers of both hands were bent together to make the palm of the hand cup-shaped, and the chest wall was rapped rhythmically with wrist strength.

  Relieve anxiety and try abdominal breathing.

  When we are nervous and anxious, not only the brain will be nervous and anxious, but also the breathing will become rapid, especially the heart beating will be accelerated. If we can take certain measures to make our breathing smooth first, then our heart will calm down and our emotional tension and anxiety will disappear.

  Abdominal breathing relaxation training can achieve this goal.

  Abdominal breathing relaxation training is to focus on the abdomen and breathe with it, so that the chest and lungs can be filled with more oxygen. There are six steps in the training process:

  The first step is to find a quiet place. When practicing, you can sit, stand or lie down with your eyes open or closed. Try to make yourself feel calm and comfortable.

  The second step is to focus your thoughts on your abdomen (from the third centimeter below the navel to the abdomen) and focus on your breathing. Then, put a hand on the abdomen, slowly take a long breath through the nasal cavity, and slowly count from 1 to 5 in your heart.

  Step three, when you take a long breath slowly, try your best to expand your abdomen and imagine a balloon being filled with air. To a certain extent, you will feel that your lung tips will be filled with air.

  Step 4: Hold your breath slowly, and then say 1, 2, 3, 4 and 5 in your mind.

  The fifth step is to exhale slowly through the nasal cavity, while meditating 1, 2, 3, 4 and 5 in your mind. When exhaling, you should slowly contract your abdomen. Imagine a balloon deflating. You can slowly bend down to exhale to 90 degrees, and make sure that the air in your lungs is completely exhaled. You feel that your front abdomen and back are about to touch.

  The feeling that the air is completely spit out is like suffocating, so you have to inhale quickly.

  Step six, repeat the above process for seven times.

  Anxious people can initially choose a fixed period of 2 ~ 3 times a day to practice, and after mastering the skills and reaching a relaxed state, they can do this kind of training anytime and anywhere.

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.

Answers to Questions about the Work Plan of Epidemic Prevention and Control in COVID-19 during the Spring Festival of New Year’s Day in 2022

1. The "two festivals" are coming soon. What prevention and control requirements should be paid attention to for residents returning home and going out?

During the "two festivals", in order to effectively control the risk of epidemic spread and diffusion, ensure that the broad masses of the people spend a healthy, safe and peaceful festival, and strengthen the safe and orderly flow of personnel, the Work Plan for Epidemic Prevention and Control in COVID-19 during the Spring Festival of New Year’s Day in 2022 (hereinafter referred to as the "Work Plan") puts forward clear requirements for the travel of personnel flowing across provinces. Considering China’s vast territory, different natural and socio-economic conditions in different places, and differences in epidemic situation, transmission risks and prevention and control priorities, all provinces (autonomous regions and municipalities directly under the Central Government) should formulate travel requirements for people within their respective jurisdictions according to the local epidemic situation and actual situation and in accordance with the requirements of scientific and precise prevention and control, and release them to the public. Please pay attention to the travel requirements during the "two festivals" and consciously implement the epidemic prevention and control measures.

2. If an epidemic occurs in the county (city, district, flag) where a resident lives, can he go out?

After the occurrence of local epidemic, the local county (city, district, banner) personnel strictly restrict travel, and implement the requirements of local epidemiological investigation, risk personnel investigation, nucleic acid detection, health monitoring and community prevention and control.

If it is really necessary for people to travel when performing specific official duties and ensuring the transportation of production and living materials, they must hold a negative certificate of nucleic acid detection within 48 hours with the approval of the local joint prevention and control mechanism, do a good job in personal protection during the journey, and abide by the provisions on epidemic prevention and control at the destination. The local joint prevention and control mechanism shall announce the approval requirements and procedures.

3. Can people from other epidemic-free counties (cities, districts and banners) in the cities where the medium and high-risk areas are located travel? If you go out, what management rules and requirements do you need to abide by?

After the occurrence of a local epidemic, people from other non-epidemic counties (cities, districts and banners) in the city where the medium and high-risk areas are located do not travel unnecessarily, and cooperate with epidemiological investigation and risk personnel investigation as required; If you really need to travel, you must hold a negative nucleic acid test certificate within 48 hours, do a good job in personal protection during the journey, and abide by the provisions on epidemic prevention and control at the destination.

4. During the two festivals, can I go to the counties (cities, districts and banners) where the middle and high-risk areas are located?

In order to prevent the risk of infection, travel to medium and high-risk areas and counties (cities, districts and banners) is strictly restricted, and those who have already traveled must abide by local epidemic prevention and control regulations.

Personnel who really need to go to perform specific official duties and ensure the transportation of production and living materials shall be implemented in accordance with relevant local prevention and control policies and regulations.

It is not necessary to go to other counties (cities, districts and banners) in the city where the medium and high-risk areas are located, and the personnel who have already gone must abide by the local epidemic prevention and control regulations.

5. During the "two festivals", will the travel of people in high-risk positions be restricted?

People in high-risk positions have more opportunities to contact infected people, virus-contaminated items and the environment during their work. If the protection is not in place, the risk of infection is higher. Recently, some places in our country have been infected by porters engaged in imported goods at ports and workers at centralized isolation points, and some places have even caused the spread and spread of communities.

Relevant departments, enterprises and institutions should register high-risk post personnel who come into contact with entry personnel, articles and environment at ports, as well as high-risk post personnel in centralized isolation places, designated medical institutions, fever clinics and imported cold-chain food processing enterprises, and strictly implement measures such as standardized protection, closed-loop management, high-frequency nucleic acid detection and zero report of daily health monitoring during their work.

During the "two festivals" period, personnel in high-risk posts should try their best to avoid traveling, and if they really need to travel, they should report to their work units to meet the conditions of leaving their jobs for more than 14 days and holding negative nucleic acid test certificates within 48 hours. Do personal protection during the trip and abide by the epidemic prevention and control regulations at the destination.

6. Can I travel with respiratory symptoms such as fever and cough?

Before traveling, if you have respiratory symptoms such as fever and cough, you should temporarily suspend your travel plan to avoid aggravation of travel fatigue symptoms, and seek medical advice in time, and then arrange travel after recovery. Do personal protection during the trip and abide by the epidemic prevention and control regulations at the destination.

7. What impact does the health code have on travel when it becomes a "yellow code"?

Health code "yellow code" personnel should fulfill their personal prevention and control responsibilities and obligations, actively cooperate with local health monitoring and nucleic acid detection, and avoid going out. After the health code is changed from "yellow code" to "green code" and there are no abnormal symptoms, you can travel normally. Do personal protection during the trip and abide by the epidemic prevention and control regulations at the destination.

8. What are the specific arrangements and requirements for college students to return to school or migrant workers to return to work after the winter vacation or the Spring Festival?

There are a large number of college students with wide sources and centralized accommodation; Some enterprises have many migrant workers and crowded workplaces. Once the source of infection is introduced, universities and enterprises are prone to cluster epidemics, which will spread rapidly in a short time.

In order to reduce the risk of the epidemic and avoid the concentration of people when returning to school, colleges or enterprises are encouraged to arrange peak-to-peak return to school; According to the actual situation, students or migrant workers may be required to hold a negative nucleic acid test certificate within 48 hours when they return to school or work.

9. During the two festivals, can you organize gatherings such as banquets? Is there a limit to the scale?

Recently, after the local epidemic occurred in some places, the epidemic spread rapidly through crowd gathering activities such as dinners, wedding banquets and funerals.

In order to reduce the risk of epidemic spread, during the "two festivals", we should strictly control temple fairs, large-scale cultural performances, exhibitions and promotions, try not to hold large-scale gathering activities, family dinners and gatherings with no more than 10 people, and advocate "delaying the happy events, keeping the funeral simple, and not holding banquets". If it is really necessary, we should minimize the scale of activities. Individuals who hold dinner activities such as banquets with more than 5 tables by themselves must report to the local community neighborhood committees or village committees to implement the epidemic prevention and control regulations. Avoid holding large-scale personnel gathering activities in towns and villages that arrive at the border.

10. What protective measures should individuals pay attention to during the "two festivals"?

During holidays, the public should strengthen self-protection and wear masks in closed places such as public transport, elevators and outdoor places where people gather. Pay attention to wash your hands frequently, cover up when coughing or sneezing, and keep a social distance of more than 1 meter. Indoor windows are often opened for ventilation to keep the air circulating. People aged 60 and above and patients with severe chronic diseases should try to reduce going to crowd gathering places.

Alert | Early warning of disease control: There is an outbreak risk of this virus!

China CDC Weekly recently released a survey on hand-foot-mouth disease virus, and Coxsackie virus A6 has become the main pathogen leading to severe cases of hand-foot-mouth disease in China. At present, Coxsackie virus A6 associated with severe hand, foot and mouth disease is evolving, and there is a risk of outbreak.

According to the research team, hand, foot and mouth disease is an infectious disease mainly caused by a variety of enteroviruses, which mainly affects infants and children. The symptoms are usually fever, oral ulcers and rashes, and the symptoms are generally mild and relieved within 7 to 10 days. However, some severe cases may have life-threatening neurological, respiratory or circulatory complications. Previously, enterovirus A71 was the main pathogen causing severe cases of hand, foot and mouth disease.

In 2016, inactivated enterovirus A71 vaccine was widely used, which significantly reduced the incidence of hand, foot and mouth disease caused by the virus. However, due to the lack of cross-protection between different enterovirus serotypes, the diversity of pathogens of severe hand, foot and mouth disease has changed.

According to the national laboratory monitoring network of hand, foot and mouth disease pathogens, the research team investigated the severe cases of hand, foot and mouth disease in China from 2012 to 2023, and obtained 74 strains of coxsackie virus A6 for analysis, and concluded that coxsackie virus A6 has become the main pathogen leading to severe cases of hand, foot and mouth disease in China. In addition, the virus related to severe hand, foot and mouth disease is evolving and there is a risk of outbreak. Therefore, it is necessary to strengthen the monitoring of severe hand, foot and mouth disease.

Among 74 severe cases of hand, foot and mouth disease related to coxsackie virus A6, 48 cases were male and 26 cases were female. The average age is about 2 years old, including 25 children under 1 year old, 26 children between 1 and 5 years old and 3 children over 5 years old. The research team said that the immune system of severe cases of hand, foot and mouth disease under 5 years old is immature, and if it cannot be diagnosed and treated in time, it may increase susceptibility and lead to serious complications and potentially fatal consequences. Therefore, the development of coxsackie virus A6 vaccine is very important to prevent severe hand, foot and mouth disease in susceptible children.

A little more news.

How is hand, foot and mouth disease spread?

Patients and recessive infected people are the sources of infection of hand, foot and mouth disease, and the proportion of recessive infection is large. Patients are contagious before onset, usually within 1 week after onset.

The route of transmission is diverse and easy to realize. The main mode of transmission is close contact, and infection is caused by direct contact with patients’ feces, herpes fluid, nasopharyngeal secretions and saliva, and contact with contaminated hands, towels, handkerchiefs, toothcups, toys, tableware, bottles, bedding and other items or environment. It can also spread through respiratory droplets, such as coughing and sneezing; Drinking or eating water and food contaminated by virus can also be infected.

How to prevent hand, foot and mouth disease?

(1) Avoid contact with children. Try not to hug, share toys, share tableware, toiletries, etc. with children to prevent cross infection.

(2) Maintain hand hygiene. Good hand hygiene is an effective measure to prevent hand, foot and mouth disease. Children should clean their hands after touching public goods, after going out to play, before eating, after going to the toilet, and after parents and caregivers go home, before processing food, after changing diapers or handling items contaminated by feces. Usually, you can wash your hands with soapy water or hand sanitizer. After contacting patients and pollutants, you should choose a chlorine-containing disinfectant with appropriate concentration to wash your hands.

(3) reduce aggregation. Crowd gathering and frequent contact are easy to spread hand, foot and mouth disease. It is suggested that children should not be taken to public places with crowded people and poor air circulation during the epidemic period of hand, foot and mouth disease.

(4) The environment is ventilated. Closed public places and rooms should be ventilated frequently to maintain air circulation.

(5) Cleaning and disinfection. Regular cleaning and disinfection of frequent contact parts, daily necessities and children’s toys; Milk utensils, tableware, etc. should be boiled and disinfected; Clothes and bedding are often dried in the sun or disinfected by ultraviolet light.

(6) vaccination. Although EV-A71 vaccine can not prevent other enterovirus infections, it can effectively prevent hand, foot and mouth disease and other related diseases caused by EV-A71 infection, and reduce the occurrence of severe hand, foot and mouth disease and death. In order to play a protective role as early as possible, children are encouraged to complete the whole vaccination before the age of 12 months. Vaccination is not recommended for children over 5 years old.

A sidewalk green belt occupying a blind road in Nanning was cut into several sections and the department responded.

Many green belts cut a blind road into multiple sections. Photo by our reporter Li Zhaoqi

  (Reporter Li Zhaoqi) "There are many green belts on the blind road, and the blind road is divided into many sections. Can such blind roads still play a role?" A few days ago, Mr. Dong, who lives in Nanning Economic and Technological Development Zone, told this newspaper that the blind road on the sidewalk of Guokai Avenue in Economic Development Zone is quite strange, and questioned whether it is reasonable for the green belt on the sidewalk to "occupy" the blind road.

  At noon on November 2, the reporter came to the Qinzhou intersection of Guokai Avenue in Economic Development Zone, and walked from the sidewalk next to the bus stop at the intersection from east to west. There was a blind road on the sidewalk, but just after walking for a while, I saw a green belt built on the blind road. The green belt was five or six meters long and cut off the blind road. Going on, there is another green belt on the blind road, which is repeated alternately, making the blind road unable to penetrate.

  After on-site visit, the green belt and blind road on the sidewalk in this section are about 100 meters in total. "Such a blind road is not only impossible for blind people to walk, but also difficult for normal people to pass." Mr. Zhang, a citizen who lives near Guokai Avenue, said that the design of this sidewalk is unreasonable. Is there a blind road or a green belt first? Why should blind roads and green belts be mixed together?

  On November 2, the reporter reported the situation to the Economic Development Zone Urban Management Bureau about the construction of green belts on the blind road at Qinzhou intersection of Guokai Avenue. On the 5th, the staff of the other party replied that they had sent people to the site to check and found that there was indeed a situation that the green belt affected the normal function of the blind road on the sidewalk of this section of the road. Since the road has not been handed over to the urban management department at present, the problem has been handed over to the project owner, who is required to make statistics on the road surface in this area, and then make a plan for rectification, and it can only be handed over after the rectification requirements are met.

618 must see before buying: 1-10K price mobile phone list summary iPhone 13 absent

This Saturday, the annual 618-year-old shopping festival will be fully opened, and many manufacturers have launched exciting offers to attract consumers to buy. However, with the development of technology, there are more and more choices for users. Today, we will refer to the 618 list launched by JD.COM to take stock of the models with the highest sales volume in each price segment.

Below 500 yuan: Tianyu > > Click me to go < < <

Starting price: 99 yuan, 98% praised.

Positioning: non-intelligent old man-machine

It’s basically difficult to buy an Android machine below 500 yuan, but the cheaper the non-smart machine, the better, so this one with a price of 99 yuan has won the favor of users. According to the official description, this one has a series of functions such as SOS one-click help, strong flashlight, oversized font, FM radio, calendar, etc., which is the most suitable.

500-1000 yuan: > > > click me to go < < <

Starting price: 599 yuan, 97% praised.

Positioning: five-star entry machine

Redmi 9A is also a frequent visitor to JD.COM’s major lists. It is stuck in 600 yuan, which is basically the cheapest Android smartphone available on the market. Redmi also launched its iterative product this year, with a price of 699 yuan, and the sales volume was also hot, ranking fifth in 500-1000.

1000-1500 yuan: 4G > > > click me to go < < <

Starting price: 949 yuan, 96% praise

Positioning: small quality king kong

The biggest advantage is still cheap, but to be honest, this mobile phone is not recommended to buy, because there are many mobile phones with strong performance at the price of 1,000 yuan, such as the newly released 4G dual card dual standby, starting from 999 yuan, which is still quite worth buying.


S "Moon Shadow White" Color Matching

1500-2000 yuan  > > > click me to go < < <

Starting price: 1499 yuan, 96% praised.

Positioning: Thousand Yuan Comprehensive Little King Kong

The 120W fast charge was brought to the price of 1,000 yuan, but the Pro version in the list was only charged with 67W, but it could be used properly for one day with a 5160mAh battery. Note 11 series is a generation that focuses on peripheral configuration. This machine is equipped with Tianji 920 liquid cooling core, and the performance-oriented cost performance party is not suitable for purchase.

2000-3000 yuan: > > > click me to go < < <

Starting price: 2199 yuan 94% praise

Positioning: Samsung 2K direct screen, beyond imagination.

Redmi K50 built-in 5500mAh battery supports 67W fast charge, the world’s first Tianji 8100 5G flagship chip, the front adopts 2K flexible OLED screen, IMX586 main camera supports OIS, built-in VC liquid cooling and X-axis linear motor, and the configuration is more comprehensive, but compared with the newly released "Little King Kong with Performance" series, the cost performance is still inferior.

3,000-4,000 yuan  > > > click me to go < < <

Starting price: 3199 yuan, 94% praise

Positioning: Samsung 2K direct screen, beyond imagination.


Seeing this, Xiaomi has occupied the position of "overlord" in the low-priced segment, and won the championship in every list except that there is no mobile phone below 500 yuan. Xiaomi 12 was released at the end of 2021, and the first batch was equipped with a new generation of Snapdragon 8 mobile platform, as well as IMX766 main camera +67W fast charging +50W wireless charging, with balanced configuration.

4000-6000 yuan 12 > > > click me to go < < <

Starting price: 4399 yuan, 95% praise

Positioning: dimension increase and speed increase.

As the saying goes, "Buy early and enjoy early, buy late and enjoy a discount". The iPhone digital generation basically follows this logic, and it is most appropriate to buy it after one or two years. Compared with the LCD screen of iPhone 11, iPhone 12 adopts a 6.1-inch OLED flagship screen named "Super Retina XDR Display" and is equipped with A14 bionic chip, which can complete trillions of calculations per second, and its performance can still be hung up on most models.

More than 6000 yuan: iPhone 13 Pro Max > > > click me to go < < <

Starting price: 8999 yuan, 97% praise

Positioning: the performance is very strong.

There is no doubt that iPhone 13 Pro Max is a "graduation machine", and its performance in A15 bionic chip is almost an inorganic rival. Although the battery capacity of this machine is only about 4400mAh, the battery life of this machine is still far beyond the industry average with the strong adjustment ability of Apple. If the budget is sufficient, it is recommended to "have no brains".

This article only summarizes the champions of JD.COM 618 mobile phone racing list, which does not mean that their cost performance is the highest. You should choose your favorite mobile phone according to your own needs, and you can experience it yourself before making a decision if you have a cable shop around you.
