Flexible sensor material sample diagram

　　A flexible sensor with a thickness of 200 microns (one tenth of the normal blood vessel thickness) is made of a special force-electricity conversion biomaterial and wrapped around a blood vessel or a heart, so that the subtle changes of the whole body blood pressure of the cardiovascular system in the early, middle and late stages of thrombosis can be clearly recorded on peripheral devices such as mobile phones, and at the same time, the slight differences of the cardiovascular wall pressure caused by the alienation of tissues and cells at the initial stage of the disease can be reflected more accurately and in real time.

　　The reporter of Science and Technology Daily recently learned from Nanjing University of Science and Technology that Professor Feng Zhangqi’s research group has created a new method for advanced prediction and real-time follow-up of cardiovascular diseases by monitoring the changes of micro-stress outside the cardiovascular wall. At present, the research group has made phased technological breakthroughs and completed the evaluation of animal clinical medicine. Related research was recently published in American Chemical Society-Nanomaterials and Devices, a top international journal in the field of nanotechnology and nanodevices.

　　New Nano-materials for Efficient Biomechanical-Electrical Conversion

　　Cardiovascular disease is the "number one killer" threatening human health, and whether the blood vessels are unobstructed is related to the normal operation of the whole cardiovascular system. Thrombosis is a small piece formed by blood flow on the surface of the inner surface of a blood vessel where it is peeled off or repaired. In the variable fluid-dependent type, thrombus consists of insoluble fibrin, deposited platelets, accumulated white blood cells and trapped red blood cells.

　　Experts say that "advanced prediction" and "real-time follow-up after operation" of cardiovascular diseases are the key points for effective clinical diagnosis of such diseases, especially for patients with severe cardiovascular diseases such as vascular tumor resection, intracardiac stent, valve, vascular replacement and intravascular stent. However, the existing molecular screening and imaging techniques lack accurate specific recognition function, which makes the advanced prediction and real-time tracking of cardiovascular diseases become a worldwide technical problem in clinical diagnosis and treatment.

　　Feng Zhangqi’s research group has long been committed to the development of bioelectronic materials and nano-devices, trying to build a new method for advanced prediction and real-time tracking of cardiovascular diseases by monitoring the changes of micro-stress outside the cardiovascular wall.

　　According to Dr. Li Tong, the first author of the paper, this time they pioneered a flexible nanofiber material with high-efficiency biomechanical-electrical conversion performance. Its thickness is only 200 microns, and it can accurately sense the pressure change and then show it in the form of voltage.

　　The material is rich in electromechanical conversion dipoles, which can generate a voltage of 1154 volts per cubic centimeter under the action of only 1000 Pascal, and has excellent stability, sensitivity and biocompatibility.

　　After being implanted in the body, the cardiovascular system can be monitored in real time through the mobile phone.

　　Based on this, the research group designed and manufactured a flexible implantable pressure sensor. They implanted the sensor into the peripheral blood vessels and heart parts of experimental animals (adult pigs), which not only clearly recorded the subtle changes of systemic blood pressure in the cardiovascular system at the early, middle and late stages of thrombosis, but also output a more accurate pressure signal, reflecting the slight difference of cardiovascular wall pressure caused by tissue and cell alienation at the initial stage of the disease in real time.

　　"Normal people’s blood pressure is beating with frequency, but when some tissues or cells are alienated in blood vessels, a fluctuating signal will be generated on the detector, no matter whether it is getting bigger or smaller, it is disordered. Once we detect this disordered signal and it doesn’t match the signal stored internally, we will issue some warnings, indicating that blood vessels may have problems." Feng Zhangqi said.

　　In the future, the flexible sensor can be implanted in the body together with cardiovascular surgery. Through the introduction of wireless signal transmitter, medical staff can track and diagnose the pathological changes of patients’ cardiovascular system in real time at clients such as mobile phones.

　　Feng Zhangqi explained: "We can convert it into an electrical signal that can be output by remote sensing. In the future technology, we can transform it into a signal received by a mobile phone. After receiving the signal, the mobile phone can share this signal with the hospital, so that it can be monitored remotely in real time."

　　At the same time, the successful development of this ultra-sensitive flexible implantable pressure sensor also provides a new method for accurate detection of micro-stress in vivo, which has great technical promotion for clinical real-time and accurate measurement of craniocerebral pressure, renal pressure and intraocular pressure.

　　Xinhuanet Beijing, August 25th (Reporter Zhang Chun) The film The Eight Hundred is based on the last battle of the Battle of Songhu in 1937. It tells the story of "eight hundred heroes" defending the four-lane warehouse in Shanghai for four days and four nights. This film is an obsession of director Guan Hu for more than ten years. After many twists and turns, it finally presents a war blockbuster that brings together many outstanding actors such as Wang Qianyuan, Zhang Yi, Jiang Wu, Huang Zhizhong, Oho Ou, Du Chun and Vision Wei.

　　On the battlefield, there is only one Suzhou River between the four-row warehouse and the public concession. In the film, the contrast scene between the north shore of the river and the south shore of the river is truly restored. From the beginning of the film project, the first difficulty faced was how to truly restore the original appearance of the battlefield. Facing this problem, Liang Jing, as a producer, said frankly: "The scene building process has been more than a year, and it really took a lot of energy and time, but now I feel that everything is particularly worthwhile."

　　Whether the scene is true or not is very important for the story to be established. Huang Zhizhong is deeply touched by this: "If an actor wants to establish a strong performance belief, you must first believe in the scene, and you must believe in the costume modeling, which will make you feel substituted, as if you were there, so that you can quickly find the feeling of that year."

　　In the movie The Eight Hundred, the camera is aimed at the soldiers in desperation, showing the audience a picture of all beings on the battlefield. Maybe at first they will be selfish, afraid of death and cowardly … … But in the end, they all overcame their fears, bravely faced life and death, and stepped forward without hesitation.

　　In the film, every soldier has grown up and changed. The youth "Dragon Boat Festival" played by Oho Ou came out of the county with a curious heart and a beautiful idea of just coming out to see Shanghai, but he didn’t expect to step into the war and experience the ultimate growth between life and death for four days and four nights.

　　"The most important thing is that it changed him from a boy to a man. It was four days and four nights, and he experienced the death of his loved ones and the departure of his brothers and sisters, which tortured his heart and led to this growth. " Oho Ou said, "The Dragon Boat Festival wants to do something for this country, which may be insignificant and his ability is limited, but he just wants to do something. Therefore, he can face it bravely. "

　　After years of preparation for the final release of the film, Liang Jing could not help but sigh: "Good things take some twists and turns, and good things are tempered. Everything is the best arrangement." Whether playing the professor’s wife in the film or the real producer, this is "a growing process" for Liang Jing.

　　(From left) Huang Zhizhong, Liang Jing and Oho Ou.

　　Scene: Restore the real scene of the battlefield and let the actors be there.

　　Xinhuanet: From preparation to shooting, the first difficulty The Eight Hundred encountered was not the setting up of the scene?

　　Liang Jing: Yes, in fact, the film took nearly 10 years from the idea to the preparation and shooting. From the time when Guan Hu sprouted in his heart to the time when a small tree finally sprouted, he always wanted to shoot and then find a venue. After the project was established in 2013, it was not until 2015 that this venue was found, because at that time, we thought about how to shoot it for a long time, whether it was in the shed or in the real scene. But the reality is that the real scene can’t be filmed. The four-row warehouse is already a museum. It can’t be blown up or filmed, and it can’t achieve the relationship between the two sides of the river that director Guan Hu finally wants to present. Fortunately, I finally found a piece of land very predestined, and the real scene was built. This scene has been built for one or two years, which means that we started preparations at the end of 2016. It really took a lot of energy and time, but now it is particularly worthwhile.

　　Xinhuanet: How did you feel when you first approached this scene?

　　Huang Zhizhong: When I first saw that scene, it should be in the construction stage. At that time, director Guan Hu invited the actors to the venue in batches. He showed everyone around and told everyone where each scene would take place and how to shoot it. I remember that we were still wearing helmets at that time, and it was still a construction site. That was the first time.

　　Xinhuanet: Was it shocked to enter the market after it was built?

　　Huang Zhizhong: I think if an actor wants to build a strong belief in performance, you must first believe in the scene, and you must believe in the costume modeling, which will make you feel substituted, as if you were there, and you can find the feeling of that year.

　　Xinhuanet: How did you feel when you first entered the arena?

　　Oho Ou: It will be very substitutive. Because my plays are mainly in the warehouse, we went into the warehouse to shoot from the beginning. In fact, not long after shooting, we felt that the whole feeling was relatively depressed. The whole tone, including the whole atmosphere, and everyone’s emotions were all in such an environment. In fact, many times, as long as you concentrate and invest, it is easy to get into that emotion.

　　Liang Jing: The realism brought by this scene is really different from that of shooting in the shed. For example, we also talked that he (Oho Ou) was photographed riding a white horse in the shed, but he could only imagine that there were thousands of horses in front, but if the real shooting could give him (thousands of horses), his performance would be different. So in fact, sometimes actors rely on the surrounding environment, opponents and atmosphere to set off their performances.

　　Character: Four days and four nights grew up rapidly in the cruel war.

　　Xinhuanet: How do you view the character "Dragon Boat Festival"?

　　Oho Ou: In fact, all his starting point is to follow his uncle and take his younger brother to see what Shanghai really looks like. This is the most basic idea of this character. But I didn’t expect to be accidentally involved in the war, which lasted for 4 days and 4 nights. I think the most important thing is to change him from a boy to a man. It’s just four days and four nights. I think he has experienced a change of mood and mentality that he might never have experienced in his life if he hadn’t gone to Shanghai, but he has to accept it if there is no way. In this process, I experienced the death of my loved ones, and all my brothers and sisters around me were gone. Therefore, this kind of torture to his heart grew very rapidly. I always thought how many things can I experience in four days and four nights? But seeing the Dragon Boat Festival, I think I can really experience something I have never experienced in my life.

　　Xinhuanet: What is the image expression of riding a white horse at the end of the Dragon Boat Festival?

　　Oho Ou: This is actually a dream of "Little Hubei". During the Dragon Boat Festival, I watched what happened to the adults in these days, and then in the eyes of "Little Hubei", I also watched his brother’s changes along the way. In the end, he saw his brother’s brave scene, so when he was dreaming, he dreamed that his brother would become Zhao Zilong, and he was still brave enough to fight against the enemy in the face of hordes.

　　Xinhuanet: The film shows the contrast between the two banks of the river. One side is bustling and the other side is in ruins. How do you interpret the feeling of looking at the other side at the window during the Dragon Boat Festival?

　　Oho Ou: Actually, when we are not filming, we will stand there and watch. When we are in the warehouse here, we look at the opposite side, which is totally different. He almost swam to the other side (Dragon Boat Festival), but he was already very close to it. He could have walked, but he still didn’t. He is just curious about everything. He came to Shanghai just to see the big Shanghai, but he didn’t expect … …

　　Change: Pay tribute to the hero and leave an unyielding monument in the first world war.

　　Xinhuanet: The professor’s wife you played also changed from irrelevant to moved to tears. How do you understand this change?

　　Liang Jing: I talked a lot with the director at that time. In fact, I think this is to explore the true side of human nature. When these people lived in the concession, he didn’t care what happened outside, because he lived very well and comfortably. In fact, there were many such people at that time.

　　But when this kind of event happens in front of our eyes and they are shocked, I believe that everyone will be touched, and this touch will definitely promote his reflection, self-awareness and self-reflection. For example, her husband, who started fighting over there, went home for dinner with soybean milk fritters, just looking back. In the end, when her husband picked up the gun, he actually had feelings. I think the south bank represents the mentality of some real people, but when the brave men across the street finally made some amazing moves, everyone was moved.

　　Xinhuanet: Your "old gourd" came to Shanghai with two children, but he escaped quietly. What do you think of this character?

　　Huang Zhizhong: First of all, he was compiled by peace preservation corps, not a regular army. He was fooled by the county magistrate, thinking that he just wanted to go there and give people a standing ovation. Then when I got there, I saw that it wasn’t like that, and I was scared. Then he found a chance to run away. I think this is an instinctive sense of security. He just wanted to stay in the green hills without fear of burning firewood, but he didn’t expect to be caught by the enemy in the end.

　　Finally, he was tied to that post. At that time, it was actually far away from the Dragon Boat Festival. I think the straight line distance should be at least 500 meters. Then the director said that you should shout hard, and there is hope if you shout out. This is also a blood relationship, let the blood pass on, and want to give the child such a hope.

　　Xinhuanet: When it comes to growth, the Dragon Boat Festival is particularly scared from the first injury, and it is very calm when it really faces death in the end. How can this change be interpreted?

　　Oho Ou: If you want to invest, you have to trust him. In fact, we can’t really shoot for four days and four nights in a row, and there will be stops in the middle, but you must immerse yourself in such an emotion, which is what Director Guan Hu told us. This is a true reflection of your feelings. In fact, it may be just a skin injury, but you feel as if you are going to die, just because this fear will make you like that. But by the end of the Dragon Boat Festival, he had seen through everything and wanted to understand. He just wanted to do something for this country, which may be insignificant and his ability is limited, but he just wanted to do something. Therefore, he can face it bravely.

　　Xinhuanet: What do you want to say most about this film today?

　　Liang Jing: I think as long as it is a good thing, it will take some twists and turns. It may not be a good thing to come out too easily. Let’s have more good things. Everything is the best arrangement, so I think these twists and turns will also make us grow, whether it’s 4 days and 4 nights, 4 years or 40 years or 400 years. I think it’s all a process of growth.

　　Remain true to our original aspiration and keep our mission firmly in mind. Looking back on the course of cultural construction in the past century, in the fierce collision between eastern and western civilizations, the Communist Party of China (CPC) people have always adhered to the guidance of Marxism, taken human development and social progress as their own responsibility, never forgotten the original, absorbed foreign countries and faced the future, thus opening a new chapter in the development of Chinese culture. Culture makes the country prosperous and the nation strong. In the new historical position and starting point of Socialism with Chinese characteristics’s entering a new era, facing new development opportunities and challenges, the Communist Party of China (CPC) people are shouldering a more arduous cultural mission.

　　1, cultural heritage, realize the great rejuvenation of the Chinese nation.

　　General Secretary of the Supreme Leader pointed out: "The prosperity of a country and a nation is always supported by cultural prosperity, and the great rejuvenation of the Chinese nation needs the development and prosperity of Chinese culture." China’s excellent traditional culture nurtured in the development of civilization for more than 5,000 years is the blood and soul of the Chinese nation, the cultural gene that Chinese sons and daughters can never give up, and the cultural support for the great rejuvenation of the Chinese nation. In the development process of nearly a hundred years, the Communist Party of China (CPC) not only shoulders the heavy responsibility of national independence and national prosperity, but also undertakes the cultural mission of the development and prosperity of Chinese culture.

　　Chinese traditional culture is a complex ideological system and cultural organism, which has both nationality, times and class. If it is simplified and abstracted into a fixed and simple individual, it will be one-sided and metaphysical.

　　Culture makes the country prosperous and the nation strong. The picture shows the campus opera festival held by Yuhua West Road Primary School in Shijiazhuang City, Hebei Province with the theme of "carrying forward the classic Chinese quintessence of opera art". Xinhua news agency

　　In the past, we have made serious mistakes, such as completely denying the value of traditional culture because of its backward or decadent elements, or unilaterally upgrading its status because of its progress or positive side, and so on. These are all things we should be alert to. In the new era, great changes have taken place in the domestic and international environment, and ideological trends or tendencies such as "cultural nihilism", "cultural conservatism" and "cultural fanaticism" are still presented in different forms to varying degrees. How to inherit and develop Chinese excellent traditional culture according to the characteristics of the new era is a major strategic task for the Communist Party of China (CPC) people in the new era.

　　On how to inherit Chinese traditional culture, Comrade Mao Zedong once proposed to "take its essence and discard its dross". The selective absorption of traditional culture can only be completed through people’s purposeful free and conscious activities. In the new era, under the guidance of Marxism, we should follow the logic of cultural development, focus on grasping and analyzing traditional culture from the perspective of historical and cultural continuity, not only understand its historical position and historical value, but also recognize its era connotation and practical significance. At the same time, we should face the future, strengthen our cultural self-confidence in the great practice of realizing the historical mission of the great rejuvenation of the Chinese nation, stick to our cultural stand, oppose "cultural hegemony" and "cultural invasion", and strive to create Chinese culture with China characteristics, China style and China style.

　　2, cultural innovation, building a socialist modernization power in an all-round way.

　　Innovation is the soul and motive force of cultural development and progress. Throughout the history of human civilization, whether in the East or the West, cultural innovation has played a key role in the long-lasting and prosperous culture. In essence, the European Renaissance in the 14th and 16th centuries was not a cultural revival movement back to ancient Greece and Rome, but a thorough cultural regeneration and cultural innovation movement, which greatly accelerated the process of western civilization. In the modern new culture movement in China, cultural innovation and ideological emancipation have always been the main theme, which greatly promoted the transformation and modernization of Chinese traditional culture.

　　History and practice have repeatedly proved that innovation is an inexhaustible motive force for the country and the nation to maintain vitality and vitality forever.

　　The Communist Party of China (CPC) has always attached importance to cultural innovation and cultural construction. In different historical periods of China’s revolution, construction and reform, the Communist Party of China (CPC) people actively cultivated and spawned revolutionary culture and advanced socialist culture under the guidance of Marxism, based on Chinese excellent traditional culture, based on practice and taking innovation as a breakthrough. At present, China is forging ahead along the goal of "two hundred years", and the Communist Party of China (CPC) shoulders the mission and task of cultural innovation entrusted by the times. "Raise the banner, gather people’s hearts, cultivate new people, promote culture and display image". Only by creating a new culture worthy of the times with the attitude of innovators can the Communist Party of China (CPC) people forge ahead in the journey of building a socialist modernization power in an all-round way and the great rejuvenation of the Chinese nation and realize their glorious dreams.

　　To promote cultural innovation in an all-round way, we must handle the relationship between cultural inheritance and cultural innovation. Chinese culture has always paid attention to the dialectical relationship between "change" (innovation) and "constant" (inheritance). Confucius once said: "Yin gained and lost because of Xia Li, so we can know it; It is clear that Zhou gained and lost because of Yin Li. Its successor or successor, though immortal, is also known. " It is precisely because of the constant changes that Chinese culture has gone through thousands of dangers and changes, but it is still endless and endless.

　　To promote cultural innovation in the new era, we must uphold the guiding position of Marxism in the field of cultural ideology. Ideology determines the direction and road of cultural innovation and development. Marxism is the world outlook and methodology of the proletariat. Under the guidance of Marxism, the Communist Party of China (CPC) promotes the innovation and development of Chinese culture. Its essence is the process of Marxism in China, and it is also the process of Chinese cultural modernization. They are not simply "foreign" and "native", decided and decided, included and included or juxtaposed. In essence, they are a kind of agreement and integration of cultural content and cultural spirit.

　　3. Learn from each other and promote the construction of a new civilized order in the world.

　　As early as more than 100 years ago, Marx and Engels revealed and predicted the globalization trend of world history and spiritual and cultural production. They pointed out that "the satisfaction of the needs of every civilized country and everyone in these countries depends on the whole world" and "many national and local literatures have formed a kind of world literature". In today’s world, with the acceleration of globalization, the conflict and integration between different cultures has become an indisputable fact. In the extremely fierce international competition, the Communist Party of China (CPC) put forward that we should respect the diversity of world civilizations, transcend the estrangement of civilizations, learn from each other, transcend the superiority of civilizations, create a new concept of civilization, promote the construction of a community of human destiny, and build a new global civilized order, which has been recognized by the vast number of peace-loving countries and people in the world.

　　In the history of human civilization development for thousands of years, equal exchanges and mutual learning between world civilizations can promote the development of culture, and vice versa. Zhang Qian’s mission to the western regions and the establishment of the Silk Road greatly promoted the prosperity of eastern and western cultures; However, the Crusade became a "reversed history of Eurasian blood and tears". Civilization or culture has nationality, diversity and equality. The cultures of different nationalities in the world communicate on the basis of equality, are valuable because of communication, learn from each other because of value, and are promoted because of mutual learning.

　　In the tide of globalization, closing the country to the outside world and blindly excluding foreigners are moving against the current, which goes against the law of the development of culture itself. Of course, belittling yourself and worshiping foreign things will also lose yourself and lose your direction. The correct attitude is to strengthen cultural self-confidence, adhere to the principle of cultural equality, take everything in an open spirit, exchange and learn from each other, absorb the strengths of all ethnic groups and adopt the wisdom of a hundred schools. On the one hand, we will "bring in" and learn from the cultures of other ethnic groups in the world to strengthen cultural exchanges and cooperation with foreign countries; On the other hand, "going out" will enhance the world influence of Chinese culture. At the same time, we must resolutely oppose and refute the western thoughts of "clash of civilizations" and "cultural hegemonism", adhere to the cultural equality of all ethnic groups, replace confrontation with dialogue, replace exclusion with exchange, resolve conflicts and promote integration, and jointly create a new concept of civilization and a new civilized order of "civilization exchange, civilization mutual learning and civilization coexistence".

　　This also cuts the robe, and that also breaks off diplomatic relations. Siraj Raval, the online celebrity of AI, has really become a street rat this time.

　　Moreover, many of them are well-known big names in the industry.

　　After MIT professor Lex Fridman deleted all the content about Siraj from his social media, Jeff Dean, the head of Google AI, also publicly announced that he would take Siraj Raval.

　　Douglas Eck, the chief scientist of Google Brain, took the lead in calling for: this scum, criticize him and take him away!

　　Rachel Thomas, co-founder of fast.ai, regrets it even more:

　　I interviewed Siraj Raval, and it’s a stain on my life.

　　Who is Siraj Raval (Siradj Laval) who was torn by a group of bosses?

　　He is a well-known broadcaster of YouTube, and his AI network course is very popular abroad. If we want to make an analogy, his popularity in English AI online class is just like that of Li Xiaolai in the currency circle.

　　Now, however, the online celebrity native’s design is crumbling. Not only is the paid online course accused of cheating money, but the published paper is also naked plagiarism-all by Ctrl+C and CTRL+V..

　　Before being accused of "cheating money", Siraj still kept his face straight, skipped live as usual, and publicly quoted his own paper.

　　However, unfortunately, Andrew M. Webb, a researcher at Manchester University, took a look at it-is it too insulting to copy and paste the paper like this?

　　Later, the drums broke through thousands of people, and more netizens came off the scene to reveal that Siraj, online celebrity, had no underwear left today …

　　△ skinned stickers reddit heat 2000

　　It is also considered that AI is too hot, and mud and sand are everywhere. Siraj shattered the three views of the AI ? ? community with his own efforts.

　　A popular online class

　　How hot is Siraj? Just look at his former followers: Jeff Dean, Ian Goodfellow, Fran? Ois Chollet… … (All have been cleared)

　　I graduated from Columbia University with a bachelor’s degree (questioned by netizens as a dropout). In 2016, I started uploading artificial intelligence and blockchain related courses on YouTube. Siraj used this style of painting-

　　△ sing rap

　　Known as the strongest Rapper in the AI world.

　　He also founded the School of AI, an AI learning community, and called it a non-profit organization, aiming to provide world-class AI education for anyone on the planet.

　　It is said that more than one million students have seen his online class. And every project he has on GitHub has thousands of stars.

　　△Siraj Raval part GitHub project

　　Three months to learn data science, six weeks of intensive learning … Almost every course is under the banner of rapid learning.

　　Moreover, talking about learning AI to make money is just a title of "The Road to Wealth and Freedom".

　　Because of this resume, eloquence and ability to fool, it was really followed at first, and the business prospects were bright.

　　However, after he launched the charging course Make Money with Machine Learning, Siraj got into trouble.

　　People set a fuse for collapse: using knowledge to pay for cheating money

　　What got Siraj in trouble was an online course he offered, "Making money by machine learning".

　　Just by listening to the name, you can know that this is a knowledge-paid online course that netizens love to see, but the price is not close to the people at all, and it is much more expensive than ordinary courses in Udacity and Coursera. After all the courses are completed, you have to pay 199 US dollars, equivalent to nearly 1300 yuan.

　　He also claimed that his energy was limited, and in order to focus on a few students, he was limited to 500 people.

　　Even so, according to this limit, this course can earn him $100 thousand.

　　Of course, with Siraj’s high popularity, it is definitely not a problem for the course to be full.

　　But the tricky thing began to be exposed.

　　The paid students later found that Siraj not only did not build an exchange group for the course, but also found that some students could not contact each other at all when they tried to communicate through the chat software Slack.

　　This is naturally intentional.

　　Siraj actually adopted the method of building a group in batches, and recruited a total of 1200 students before and after, that is to say, in the name of "limited" marketing, taking advantage of the information gap and secretly expanding enrollment, with the aim of making as much money as possible.

　　Students who know the truth are angry because of "false propaganda", and they also find that the quality and commitment of the course are just like the propaganda at the time of registration.

　　One of the important things is personalized help, which is completely broken.

　　Siraj just released a 30-minute video course every week and gave everyone a question-and-answer period. What about focusing on a few students?

　　More ironically, students find that the course content can be found for free on GitHub … What’s more?

　　Holding something that is free and open source, and then deleting the license to claim originality to make money, itself violates the spirit of the open source community and is despised by the majority of programmers.

　　As a result, students have asked for a refund and dropped out of class, and the momentum is growing.

　　But how can Siraj, who has a good fortune, easily let go of the meat in his mouth? He moved the students to Discord, another chat software, and set up a special program. All messages containing the word "refund" were deleted.

　　If someone goes to his YouTube or Twitter to reply and ask for a refund, Siraj will always black them out.

　　Siraj then added a refund policy to the website, but the requirement is that the refund must be completed within 14 days after registering for the course.

　　However, this obviously violates California law, because consumers have the right to ask for a refund within 30 days.

　　In the end, Siraj couldn’t stand the huge pressure of netizens’ public opinion, or it may be because he was worried about taking a lawsuit. After weighing it again and again, he announced that students who were dissatisfied with the course and paid within 30 days could provide a full refund.

　　Of course, after this battle, the online celebrity people’s establishment collapsed.

　　Lex Fridman, a teacher and researcher at MIT who had been "pink" Siraj before, was also found by netizens last week to quietly delete all the recommendations about Siraj.

　　The paper was found to be plagiarized at pixel level.

　　However, things are not over yet.

　　What completely collapsed Siraj’s design was that he copied other people’s academic papers at pixel level.

　　Below this post, a netizen said that Siraj’s liar nature had long been discovered, especially from his "Neural Qubit" video. In this video, he just summed up the results of Nathan Killoran’s paper and added some subjective and controversial biological theories, but claimed to be his own research.

　　Even the code he posted to GitHub just copied and pasted other people’s versions, and deleted the license and changed some constants.

　　Yesterday, someone even analyzed the differences between Siraj and Nathan Killoran in detail on Twitter, which was equivalent to convicting Siraj of plagiarism.

　　It can be seen that Siraj is almost a piece of plagiarism. The charts, formulas and even symbols used in the two articles are exactly the same.

　　Even careful netizens found that Siraj’s plagiarism can be described as "true pixel level", that is, really taking screenshots.

　　Generally, people who do academic writing will use LaTeX to edit formulas, but the resolution of formulas in Siraj’s paper is actually lower than that in the original paper.

　　Yes, the chart in his paper is so vague. A reasonable explanation is that he just copied and pasted the pictures in other people’s papers.

　　Maybe even "washing the manuscript" feels laborious.

　　Of course, some people say that maybe Siraj doesn’t know LaTeX at all, his college grade is B, and he hasn’t attended graduate school, so he doesn’t have the ability to write professional academic papers.

　　But even if you can’t LaTeX, this plagiarism is too careless. Undergraduate students encounter poor resolution when pasting formulas, and they also know to edit in Word instead of pasting pictures directly.

　　No wonder some people commented that this is simply a plagiarism of Ctrl+C and Ctrl+V levels.

　　Siraj apologizes for his resignation.

　　It is not very nice to say that the expansion of Siraj online courses is just a "just meal" gesture, but copying academic papers and open source code is equivalent to being sentenced to death in the circle.

　　Many big names who had paid attention to Siraj have said that they have cancelled their attention, including Google legend Jeff Dean.

　　An AI enthusiast said that Jeff’s statement is very important. Many people can avoid Siraj’s scam when they see Jeff taking the customs.

　　Siraj saw the momentum, too, and never carried it again.

　　After experiencing a rare silence, in the face of all kinds of evidence dug up by netizens, Siraj finally apologized on his Twitter a few hours ago and deleted the paper suspected of plagiarism on the whole network.

　　However, some people are still kept in the dark, such as the European Space Agency, and even invited him to give a speech at the event.

　　It’s just that there were as many fans as there were at the beginning. Enthusiastic netizens volunteered to set up an "anti-flicker consultation hotline" and sent an email to the European Space Agency, saying that Siraj’s academic ethics was questioned and called for a boycott of his speech.

　　It is also worth noting that Siraj has never forgotten to come to China to collect money over the years.

　　Last year, the domestic blockchain community invited it to cooperate with it, and even called it "Jesus in the machine learning world."

　　Of course, it is not without clues that Siraj misbehaves now.

　　However, because he had a high reputation in the field of machine learning before, and he was too good at marketing, the previous accusations of netizens about his money did not form a momentum.

　　Moreover, Siraj was recognized at first, and it did have something extraordinary. After all, in this field, lively and diverse lecture forms are really unique.

　　However, the motivation is impure, breaking through the bottom line of academic ethics, and trying to make money by using the information gap. In the end, people will inevitably bring about their own destruction.

　　In short, you have to pay it back sooner or later.

　　Fraud in the field of AI will sooner or later be hanged. Right?

All relevant units:

　　Recently, after two consecutive cases of positive people were detected in the building where a socially infected person was located in this city, the basic information of all company personnel in the building was not provided, resulting in that the infected person was not required to be isolated at home, but only worked at home. Because the infected person has a trajectory of social activities, it has triggered the risk of social communication. It reflects that there are still some problems in the epidemic prevention and control work of some units, such as unclear base, untrue data and inadequate implementation of responsibilities. In order to further compact the responsibility of the four parties, strengthen the awareness of epidemic prevention, and shoulder the responsibility of epidemic prevention, according to the latest deployment requirements of epidemic prevention and control in the city, the basic ledger and management of personnel in industrial and software information service enterprises in the near future are emphasized as follows:

　　First, strengthen the management of basic information ledger

　　All industrial and software information service enterprises should learn a profound lesson, thoroughly find out the base number of employees (including all kinds of hourly workers, short-term workers, temporary workers, interns, outsourcing, labor dispatch, maintenance, security, cleaning, canteens, related security personnel, etc.), and establish and dynamically update employee basic information accounts (including core information: personnel name, ID number, mobile phone number, detailed current address, family contact, etc.); Optional information: building layout, tenant distribution and contact information of this unit, seat distribution of all personnel’s office space, personnel’s business trip, recent nucleic acid detection, unit gathering activities and meeting organization, visitor record, etc.), and register all kinds of visitors to ensure that the source can be traced and the destination can be traced.

　　Second, make good use of personnel nucleic acid comparison register

　　Adhere to the principle of "all examinations should be carried out" and "all examinations should be carried out", and strengthen the management, tracking and supervision of personnel’s nucleic acid detection. Each industrial enterprise should designate a person to be responsible for strengthening the epidemic prevention management of its staff by using the nucleic acid comparison register, do a good job in information collection and dynamically maintain the register; In addition to regular employees, temporary employees, new employees and related service personnel should also be included in the management scope, and those who leave their jobs should be eliminated in time; It is necessary to promptly urge relevant personnel to carry out nucleic acid testing in accordance with the regulations, effectively control the "entry barrier", prevent risk personnel from entering the place of resumption of work and production, and build a strong internal "firewall" for enterprise epidemic prevention. All districts should check the register in time and urge and guide enterprises that fail to carry out relevant management work as required to carry out testing as required.

　　Third, timely cooperate with the flow adjustment to share the information ledger.

　　Implement the "four early" requirements, once an epidemic situation occurs, find out the risk personnel and points as quickly as possible, truthfully provide the basic information of the full-caliber personnel of the unit, cooperate with the work of tracing the source of flow, screening for landing, investigation and control, and resolutely prevent the leakage of people and the loss of control. If there are home office workers, we should adhere to the principle of "who manages and who is responsible", make overall plans for the specific arrangements and education management of employees’ home office, urge their employees to implement the requirements of community epidemic prevention, report their personal health status and activity track daily, and strictly prevent leakage of management.

　　Four, strictly implement the requirements of normalized nucleic acid screening.

　　Do a good job in the normal nucleic acid detection and screening of "people, things and environment" and regular detection and screening of key departments, key populations and key areas. For 34 key groups such as cold-chain cold storage, imported non-cold-chain goods and security guards, which are involved in the fields of industry and software information services, we should carry out all-out inspection, and carry out nucleic acid testing according to the requirements of their respective industries, including cold-chain cold storage employees once a day, imported non-cold-chain goods employees, security guards and canteen employees once every two days, and other stakeholders with wide contacts should also encrypt the frequency of nucleic acid testing, so as to gain time for finding the epidemic risk at the first time and effectively handling it.

　　I hereby inform you.

Recently, Norovirus infection broke out in some primary schools and kindergartens in Nanchang, leading to vomiting and diarrhea.

Remind students and parents that when there is a suspected or confirmed epidemic situation of infectious diseases, they should not conceal their illness and are not allowed to attend classes with illness. It is required that many students in the school should report their illness to the disease control department within 2 hours. If a suspected patient is found, it shall not be concealed or lied, and offenders shall be held accountable to the relevant personnel.

Just today, Nanchang CDC issued a health warning in November. In addition to norovirus, Nanchang CDC reminds the public that autumn and winter are also the high incidence periods of hand, foot and mouth disease, infectious diarrhea, tuberculosis and influenza.

In addition, according to the data released by the Provincial Health Planning Commission, nearly 10,000 cases of hand, foot and mouth disease, other infectious diarrhea and influenza were reported in the province in September.

How to survive the high incidence of the virus?

The following, no matter how busy, also want to see.

Upwelling vomiting and diarrhea occurred in many schools in Nanchang.

In recent days, some primary schools and kindergartens in Nanchang have had symptoms of children’s collective vomiting and diarrhea, and even many parents are worried about their children’s food poisoning. After investigation by the health and disease control department, they were verified as norovirus infection.

Experts from Nanchang CDC said that Norovirus infection has been at a high incidence in the near future, and it is very contagious. The virus is generally susceptible to people of all ages. In addition, the lack of long-term immunity after infection can lead to repeated infection. There are also many ways of infection, including fecal-oral route, contact with pollutants, aerosol air and so on.

Expert advice

Norovirus infection spreads rapidly, with vomiting in children and diarrhea in adults. The public need not worry too much. Although there is no vaccine at present, Norovirus diarrhea is a self-limited disease, which can usually heal itself in about a week. The key to prevention lies in personal hygiene, food hygiene and drinking water hygiene; Pay attention to hand hygiene, wash your hands before and after meals, and do not eat cold food; Keep indoor air circulation, and often open the window for ventilation.

There are more than 60 cluster epidemics of hand, foot and mouth disease.

It is reported that from the epidemic situation of legally reported infectious diseases in Jiangxi Province in July, August and September 2018 announced by the Provincial Health Planning Commission, hand, foot and mouth disease is in the top three among Class C infectious diseases (July and September are the first).

According to disease control experts, hand, foot and mouth disease is an infectious disease caused by a group of enteroviruses (Coxsackievirus A16 and Enterovirus 71 are the most common), which mostly occurs in children under 5 years old, and the incidence rate is the highest under 3 years old. At the same time, it is also an eruptive disease, and the eruptive parts are mainly concentrated in the mouth, hands, feet and other parts, hence the name. But the disease is not as simple as a rash, and it is even serious about the child’s life. The disease is highly contagious, mainly through the digestive tract, respiratory tract and close contact.

Statistics from Nanchang CDC show that hand, foot and mouth disease (HFMD) is high this year, and there are more than 60 cluster epidemics according to network monitoring. In November, the temperature and humidity meet the growth and reproduction of HFMD, and there is still a risk of transmission. Family protection is very important to prevent the delay.

Expert advice

Hand, foot and mouth disease is an intestinal infectious disease. At least 20 serotypes of group A enterovirus can cause hand, foot and mouth disease, and children vaccinated with EV71 vaccine may still be infected with other types of hand, foot and mouth disease. EV71 hand, foot and mouth disease has a high proportion of severe cases, which can be fatal. Vaccination with EV71 vaccine can effectively reduce the occurrence of severe cases of hand, foot and mouth disease. Parents should keep in mind the 15-word preventive formula: wash hands frequently, open windows frequently, drink boiled water, eat cooked food and dry clothes and quilts.

Experts remind that if there are children suffering from hand, foot and mouth disease and other children in the family, they should be kept in isolation, and it is best to live separately. During the illness, children should try to avoid going out, not to go to kindergartens and public places where people gather, and avoid contact with other children. The time limit for home isolation is one week after all symptoms disappear.

High incidence of tuberculosis in autumn and winter, long cough, don’t be a cold.

Last winter, a cluster epidemic of tuberculosis occurred in No.4 Middle School in Taojiang County, Hunan Province, which aroused widespread concern in society.

According to experts, tuberculosis is a contagious, chronic and slow-onset infectious disease. After tuberculosis infects the human body, it can form tuberculosis lesions in almost all human organs and tissues, but it is most common in the lungs. There are about 1.3 million new cases of tuberculosis in China every year, and 54,000 people die of tuberculosis every year.

According to experts in disease control, after the weather gets cold, there are always people who cough, and when they cough, they always feel that the improvement is very slow. People who cough don’t take it seriously, only think that it is caused by a common cold, and they are shocked by the seriousness of the matter until the condition develops seriously or the physical examination.

Experts explained that the increasing number of asymptomatic tuberculosis patients, mild and atypical initial symptoms of tuberculosis, and easy to be misdiagnosed as upper respiratory tract infections such as colds are the most important obstacles for school tuberculosis patients to delay diagnosis. According to the experts of disease control, if the tuberculosis patients have to be suspended from school for treatment during the infectious period, and they can go back to school to continue their studies after medical review, the process is generally 6-8 months or even longer.

Expert advice

The high-risk group of tuberculosis is a group with poor immune function. Secondly, irregular life and overwork are also high-risk groups of tuberculosis. Students in school often stay up late, lack of exercise and poor nutrition, which leads to decreased physical resistance, low immunity and easy infection and tuberculosis.

Experts remind that vaccination with BCG can effectively prevent tuberculosis; Patients with infectious tuberculosis should not go to public places, do not cough or talk to others at close range, and cover their nose and mouth with handkerchiefs when coughing or sneezing to avoid infecting others; Increase the frequency and time of window ventilation to keep the indoor air fresh.

　　Mp3 is still here today, not the player of that year. The author’s impression of mp3 players began in high school. At that time, I was still using a heavy tape walkman, but "wearing headphones and hanging an mp3 player around my neck" has quietly become a campus fashion. At that time, the mp3 player was relatively large, connected with wired headphones, and looked from a distance, as if a stethoscope was hung around his neck.

　　At that time, I was lucky enough to experience my roommate’s mp3 player. It was very convenient to listen to songs, but it was inconvenient to find songs. The playing modes were only sequential playing, random playing and single loop. As an expert in using the rewind button of the walkman, I can judge the position and rewind time of a song according to the diameter of the tape reel, so the mp3 player is really "hehe" in my eyes.

　　Unfortunately, the good times didn’t last long. As soon as I graduated from high school, digital products such as walkman and tape were swept into the history museum along with the "rewind skills" that the author was proud of. But they were not killed by mp3 players, but by more advanced mobile phones. When I was in college, I used a mobile phone called "Nokia". Now children may not have heard of this brand. Back in those days, Nokia dominated the mobile phone industry with its Symbian intelligent system. It could not only listen to mp3 music, but also watch movies on a 2: 00-inch screen. Of course, more importantly, it saved money on mp3 and mp4 players.

　　However, the author’s college roommate Z still keeps the habit of using mp3 player. His mp3 player is a famous brand product in Japan, which costs thousands of dollars. It is said that the sound quality is excellent when used with a pair of German brand headphones costing more than 300 yuan. I’ve listened to it, too, and it’s really good, but if it’s too good to be wanted, it’s not too bad.

　　This Z student not only has an mp3 player, but also an mp4 player with a bigger screen than his face, which is the originator of the current big-screen mobile phone. At that time, I thought that it was just around the corner for mobile phones to replace mp3 and mp4 players, and the practice of Z students could only be simply evaluated as rich and powerful.

　　However, classmate Z gave me an unexpected answer. He said: "the computer is very powerful, right? But every time I turn on the computer, I always change my original intention unconsciously. For example, I originally wanted to watch a movie, but I played a game." I wanted to listen to music, but I got online. So I think that computers are used to play games online, mp4 players are used to watch movies, and mp3 players are used to listen to music. "

　　Some people may say that this is your classmate Z’s poor self-control. But just imagine, if you were given a computer with Internet access and full of movies, music and games to learn English, how long would you last without external supervision?

　　Once upon a time, the author was superstitious about self-control, but if we contact the supervision mechanism, we will find that in a relaxed environment, facing a world full of temptations, people basically have no self-control, and the probability of getting lost or even sinking is extremely high.

　　"The keyboard starts and ends, and you know exactly that 88 keys are there. You can’t go wrong … I like it, and I can easily cope with it … in that infinite spreading city, everything is there, but there is no end, no end at all. What I can’t see is the end of all this, the end of the world. " At the end of the movie legend of 1900, the hero 1900 uttered such a sigh.

　　I don’t know how many netizens have had similar ideas to 1900 when facing computers and mobile phones. Or perhaps, many netizens have lost themselves in the abyss of network information and forgotten the original intention of using computers and mobile phones before they have time to express their feelings.

　　Many years later, when I bought a certain brand of electronic paper book reader, I remembered the classmate who listened to music with mp3 player in college. Someone asked me: Why spend more than 800 yuan to buy a digital product that is slow to respond and can only read books?

　　To this, I can only answer: because my self-control is too poor.

In the first half of this year, China’s cross-border e-commerce import and export was 1.22 trillion yuan, up 10.5% year-on-year, which was 4.4 percentage points higher than the overall growth rate of China’s foreign trade in the same period. Last year, China’s cross-border e-commerce import and export increased by 1.2 times compared with 2018.

Cross-border e-commerce is becoming the new engine of foreign trade growth in various places. Guangdong, Shandong, Zhejiang and other major foreign trade provinces and Tibet and other open areas along the border are exploring new modes of innovation and development in light of their own reality. Among them, overseas warehouses, as a new foreign trade infrastructure, play an increasingly important role in cross-border trade.

Recently, a batch of fitness equipment produced by Guangdong Zhongshan Yingliang Health Technology Co., Ltd. was transported to overseas warehouses of cross-border e-commerce in the United States by international freighters. "Under the guidance of Zhongshan Customs, we began to transform and go to sea through cross-border e-commerce." Wen Yanni, the business manager of the company, said, "All our orders in the US market are shipped from overseas warehouses, which is more efficient than the domestic direct delivery model."

As a leading cross-border e-commerce enterprise in Dongguan, Guangdong Province, Shangrui Technology Co., Ltd. has driven nearly 100 traditional manufacturing enterprises to expand overseas online markets. Cheng Tianle, chairman of the company, said: "More than 90% of our orders are shipped from overseas warehouses."

Up to now, Guangdong Province has built all kinds of overseas warehouses in the world with a total area of nearly 6 million square meters. In the first half of this year, the import and export of cross-border e-commerce in Guangdong Province reached 427.34 billion yuan. From 11.3 billion yuan in 2015 to 843.3 billion yuan in 2023, the average annual growth rate of cross-border e-commerce import and export in Guangdong Province is as high as 71.4%, accounting for more than one-third of the national cross-border e-commerce import and export.

Guanxian, Liaocheng City, Shandong Province also actively guides enterprises to develop overseas warehouse layout with the help of the business policy of stabilizing foreign trade and benefiting enterprises. "We encourage enterprises to set up a guanxian brand commodity exhibition center in public overseas warehouses by means of’ exhibition before warehouse’ to support the venue rent; Encourage enterprises to build agricultural products group buying platforms or independent stations to support construction and operating expenses. " Guo Huawei, Party Secretary of guanxian Commerce and Investment Promotion Bureau, said.

A few years ago, the overseas warehouse project of guanxian Baijia Food Co., Ltd. was recognized as a key public overseas warehouse by the Shandong Provincial Department of Commerce, and successfully applied for support funds. "In the first half of this year, our overseas warehouse turnover was US$ 30.1 million, serving 42 domestic enterprises." Song Xiangzhen, manager of the international trade department of Baijia Food Co., Ltd. said.

Linyi City, Shandong Province has continuously expanded its overseas network layout, implemented the "Overseas Warehouse Plan", and encouraged enterprises to build overseas shopping malls and warehouses in countries and regions, RCEP member countries and emerging market countries in the "Belt and Road". At present, there are 31 overseas shopping malls and warehouses in Linyi City.

In the Lanhua Overseas Shopping Mall in Linyi, China, Longren City, Gyeonggi Province, South Korea, Linyi specialty products such as wickerwork table lamps, Kadele building blocks and pet products are dazzling. This overseas Linyi Mall opened in September last year. It integrates Linyi’s high-quality products according to the mode of "exhibition before warehouse". It has the functions of display, experience, sales and warehousing, and is also an upgraded version of the traditional overseas warehouse. Guan Zhaojun, Chairman and President of Lanhua Group, introduced that the company has also built overseas shopping malls and warehouses in Malaysia, the United States, Kazakhstan and Thailand, and cooperated to build a "Sino-Vietnamese border warehouse" in the estuary of Yunnan, continuously developing international trade business and selling Linyi specialty products overseas.

In recent years, the trade between China and Nepal has shown a sustained growth trend. After investigation and on-the-spot investigation, Tibet Lhasa Bureau of Commerce and Lhasa Zangni International Supply Chain Management Co., Ltd. completed the construction and operation of overseas warehouses in only three months. "Lhasa encourages foreign trade enterprises to build overseas warehouses, and will support enterprises identified as public overseas warehouses up to 5 million yuan. At the same time, 50% rent subsidy will be given to enterprises that lease overseas warehouses. " Zhao Hancai, deputy section chief of the Foreign Trade and Economic Cooperation Department of the Lhasa Municipal Bureau of Commerce, said that after the opening of the cross-border electronic commerce Comprehensive Experimental Zone, Lhasa has made great efforts in optimizing the customs clearance environment and exploring the international market, making cross-border electronic commerce’s industry bigger and stronger.

"China goods are very popular in Nepal. We are purchasing small household appliances, clothing, shoes and hats and other goods to send to Nepal. " Fu Guangyi, general manager of Lhasa Zangni International Supply Chain Management Co., Ltd. introduced that the cross-border e-commerce model enables goods to be delivered to overseas consumers faster through the pre-stocking of overseas warehouses, saving logistics costs, enriching export categories and expanding overseas consumer markets for local traditional foreign trade enterprises.

According to reports, relying on Nepal’s overseas warehouses, the Lhasa Municipal Bureau of Commerce will cultivate and attract a number of key cross-border e-commerce enterprises and service providers, and lay a good combination of cross-border e-commerce, overseas warehouse opening and overseas participation to expand export channels. This year, the Lhasa overseas warehouse project plans to complete a total export trade of about 400 million yuan.

In order to better serve cross-border e-commerce, various localities continue to introduce new policies and measures.

In order to accelerate the cultivation of new formats such as cross-border e-commerce, the Guangdong Provincial Department of Commerce has taken the lead in formulating opinions on the planning and construction of cross-border e-commerce parks, and has successively issued policies such as high-quality development of cross-border e-commerce and sustained and stable development of cross-border e-commerce.

Pan Wenqing, deputy mayor of Lhasa, said that since the approval of the cross-border electronic commerce Comprehensive Experimental Zone in Lhasa, the city has formulated and introduced cross-border e-commerce support policies, introduced and cultivated cross-border e-commerce business entities, made every effort to build a cross-border e-commerce industry ecosystem, and continuously enhanced the endogenous motivation of foreign trade. In the first half of this year, Lhasa achieved a total import and export value of 2.594 billion yuan, a year-on-year increase of 183.3%, and foreign trade showed a good development trend.

Since the beginning of this year, the Zhejiang Provincial Department of Commerce has further promoted the cultivation of cross-border e-commerce, and continued to carry out the action of "opening stores around the world, launching brands to the sea, and piloting independent stations" to promote the docking of high-quality service providers’ resources with enterprises in industrial belts. At present, there are 206,000 active cross-border e-commerce export online stores in Zhejiang Province, and there are over 600 enterprises with annual sales of over 100 million yuan. According to data released by Hangzhou Customs, in the first half of the year, cross-border e-commerce exports in Zhejiang Province reached 179.93 billion yuan, a year-on-year increase of 38.5%.

Recently, a number of self-designed oil-paper umbrellas of Hangzhou Anruosu Technology Co., Ltd. were successfully exported to the European market on special cross-border e-commerce cargo flights.

"Since the opening of an online store on the cross-border e-commerce platform in February this year, the sales of oil-paper umbrellas have increased month by month, and now they can receive more than 100 overseas orders on average every day." Li Yanshuang, the person in charge of the company, said that when traditional culture embraces emerging formats, Chinese-style cultural products such as oil-paper umbrellas and horse-faced skirts are continuing to "circle powder" in foreign consumer markets.

Zhu Cheng, president of Zhejiang Bichuang Technology Group Co., Ltd., believes that cultural tourism products will become a new variety of cross-border e-commerce track and will usher in huge market opportunities in the future. At present, the company intends to unite Guangdong? Sub-industry investment groups, etc., work together to create an industry-oriented park that integrates "cross-border e-commerce+cultural (cultural) industry incubation+overseas social media+industrial funds". At the same time, build an ecological service chain to serve the national culture and tourism enterprises, and boost China’s cultural tourism products to the world.

In order to support more traditional enterprises to better connect with the international market, Hangzhou Customs has made efforts in strengthening policy guidance and improving supervision and support, unblocked the channels for enterprises to "go to sea" and supported the normal operation of cross-border e-commerce export cargo flights. The Zhejiang Provincial Department of Commerce will also establish a cross-border e-commerce enterprise cultivation library, focusing on promoting traditional industrial and trade enterprises, specialized and special new enterprises, commercial and trade circulation enterprises, domestic e-commerce sellers, etc. to carry out cross-border e-commerce business and form new cross-border e-commerce increments.

According to CCTV news, the reporter learned from the press conference on the prevention and control of COVID-19 epidemic in Baise City, Guangxi Province held in Debao County on the afternoon of the 14th that some people found that they had never been to medium and high-risk areas, but the health code turned into a yellow code or a red code. If this happens, it can be transcoded in the following ways:

First, through the abnormal feedback function of Guangxi Health Code-Scan Code Anti-epidemic applet, we can make independent complaints about personal health code abnormality, upload screenshots of travel cards, screenshots of nucleic acid detection reports, health commitment letters and other supporting materials, and the administrators of counties, townships or towns, streets and districts will complete the processing within 24 hours after receiving the information reminder of the health code abnormality feedback processing list within their jurisdiction.

The second is to report to the unit, the property of the residential area and the local community and village by telephone. By the county or township, street zoning administrator to meet the conditions of restoring the green code personnel transcoding.

Third, other situations can be consulted and reflected through the 12345 hotline.
