Close to the limit of insolvency According to the director of Sao Viet car company, production and business revenue is almost zero, but every day still has to bear countless expenses such as bank interest; rent for factories, warehouses, salaries to support officials, employees, drivers; road maintenance fees … A series of passenger transport enterprises are in the “swallowing” scene. “Before the epidemic, on average, each month we spent about 3 billion dong on salaries and bonuses for drivers and employees. However, today, even though there is no revenue, we still have to “burden” nearly 1 billion dong/month “- Mr. Bang stated. Not only road transport, the air transport market has suffered the most severe decline ever, prompting the Ministry of Planning and Investment to issue a warning that the solvency of enterprises is declining close to the limit of insolvency. maths. For example, the national airline of Vietnam (Vietnam Airlines), it is expected that the loss of the first quarter of 2021 will be at VND 4,800 billion and in the first six months of the year may reach VND 10,000 billion. Currently, the amount of overdue debt has reached VND 6,240 billion and is in a very difficult situation. Vietnam Airlines has more than 9,000 employees who are on unpaid leave and temporary suspension of labor contracts. Most transport businesses are facing great difficulties due to the Covid-19 epidemic Vietnam Railways Corporation (VNR) also lost 50% of passenger transport revenue in the past 5 months due to people restricting travel, the railway industry had to cut many passenger trains. Mr. Nguyen Cong Hung, Chairman of the Hanoi Taxi Association, said that the number of passengers decreased by 80%-90%, revenue fell seriously, and workers’ lives were difficult. A series of taxi companies are facing the risk of bankruptcy, and bad debts are at high risk of increasing in the banking system. Therefore, recently, the Taxi Associations of Hanoi, Da Nang and Ho Chi Minh City have jointly signed a document to send to the Prime Minister, proposing to support taxi transport enterprises to overcome difficulties before the Covid-19 pandemic. Proposing many solutions Facing the above situation, the Prime Minister has just assigned the Ministry of Transport to consider and propose policies and solutions to support passenger transport enterprises facing difficulties due to the Covid-19 epidemic. to border gates and between regions in the domestic market. According to Mr. Tran Bao Ngoc, Director of the Transport Department (Ministry of Transport), since the outbreak of the epidemic, the Ministry of Transport has proposed policies and solutions to support transport enterprises in difficulty. Regarding the solution to remove the vehicle inspection cycle, Mr. Ngoc said that the Ministry of Transport is amending Circular No. 70/2015 in the direction of adjusting the inspection cycle of passenger cars of all kinds up to 9 seats with transportation business. , adjusted from 18 months to 24 months for the first cycle and from 6 to 12 months for the recurring cycle. In addition, the Ministry of Transport also proposed that the Government delay the time of sanctioning transport enterprises that do not install surveillance cameras due to the impact of the Covid-19 epidemic. Regarding the proposal to exempt road maintenance fees until the end of this year, Mr. Ngoc said that in order to remove difficulties for those affected by the Covid-19 epidemic, Circular 112/2020 of the Ministry of Finance allows to reduce collect road user fees from January 1 to June 30, 2021. “The Ministry of Transport has proposed to the Government to reduce value-added tax to 0%, reduce 50% of corporate income tax for industries seriously damaged by the epidemic. Besides, delay payment of tax amount for 6 months for 6 months. arrears until December 31, 2021 and there is no fee for parking, parking and picking up passengers at the airport, train station, port and 50% discount on service prices through the bus station for passenger cars. sign for new registered vehicles for transport business until December 31,” said Mr. Ngoc. It is still difficult to access support policies As a large passenger transport enterprise in Quang Ninh province, Mr. Doan The Xuyen, director of Phuc Xuyen Co., Ltd., said that the company has over 300 vehicles that have stopped working but still have not been exempted from road maintenance fees because of cumbersome procedures. . For example, to be exempted under the regulations of the Ministry of Finance, the vehicle must stop working for 30 days or more, then return the badge and be certified by the Department of Transport. “You can stop for less than 30 days to be able to run again, then you have to apply for a new badge. Many businesses still have to pay even though the car is not running because they are afraid of procedures,” said Xuyen.

(Photo: Hoang Hung/VNA) In the written response to the Vietnam Automobile Transport Association and the three-region taxi association, the Ministry of Transport agreed to allow car inspection cycle will increase from 18 months to 24 months to remove difficulties for transport businesses affected by the COVID-19 epidemic. Currently, the Ministry of Transport is directing agencies and units to advise on finalizing the draft Circular amending Circular No. 70/2015 regulating the inspection of technical safety and environmental protection of vehicles. road motorized traffic. “The inspection cycle of passenger cars of all kinds up to 9 seats with transportation business will be adjusted from 18 months to 24 months for the first cycle and from 6 to 12 months for the periodic cycle,” said the leader. The Ministry of Transport said. For the proposal to have appropriate policies and mechanisms for BOT investors to reduce road use fees according to Circular No. 112/2020 of the Ministry of Finance, the Ministry of Transport said Circular No. 112/2020. of the Ministry of Finance stipulating the rate of road use fee (toll collected per vehicle) for automobiles doing transport business of transport enterprises, transport business cooperatives, and transport business households. “The collection of road service fees is not specified in Circular No. 112/2020, so investors do not have to follow the guidance of this Circular,” the leader of the Ministry of Transport affirmed. . On the other hand, a number of investment projects in the form of public-private partnerships managed by the Ministry of Transport have reduced road user service fees; BOT projects have not been considered to increase road use prices, although it is time to increase prices in the last 3 years in order to share and harmonize the interests of the State-people-enterprises. Moreover, BOT investors are also businesses and are also affected by COVID-19 epidemic due to the reduction of vehicle traffic through the station, revenue will be reduced, affecting the financial balance of the enterprise; increase in interest expense and operating expenses of the business. Regarding the proposal for exemption from submission road maintenance fees By the end of this year, according to leaders of the Ministry of Transport, this agency is coordinating with the Ministry of Finance to comment on amendments to Circular 112/2020 and related circulars to assist in removing difficulties for production and business in response to the COVID-19 epidemic chaired by the Ministry of Finance. Previously, in 2020, the Ministry of Finance coordinated with relevant ministries and agencies to develop and issue Circular No. 112/2020/TT-BTC dated December 29, 2020 providing for the extension of the reduction period. fees and charges (mainly reducing fees in the field of transportation (road use fees; fees, aviation fees…) until the end of June 30, 2021 to support and remove remove difficulties for production and business, ensure social security in response to the COVID-19 epidemic.

Chrome OS’s cycle is shortened to once every four weeks. Previously, Google usually released updates for Chrome browser with a 6-week cycle. However, in March 2021, Google announced about shortening the update time to improve gaps and patch bugs. For more than a decade, every six weeks, Chrome has hit a new milestone, bringing security, stability, speed, and simplicity to users and the web. In addition, Google’s shortening time is also to match the cycle of other competitors, like FireFox, which shortened the time to release new updates by month starting last year. Due to this schedule, Google will actually skip one of the scheduled Chrome OS updates. Accordingly, Google will switch directly from version M94 to M96, skipping M95. The new schedule does not apply to enterprise and educational systems. These systems will have an update schedule once every six months. Google promises to have more details on this soon.

Source of pictures of on-site discussion at the forum: Photo by reporter Zhang Jian Accelerating the construction of a new development pattern with the domestic cycle as the main body and the domestic and international double cycles mutually promoting each other is a major adjustment and improvement of my country’s economic development strategy and path in the “14th Five-Year Plan” and a longer period of time in the future. At present, many cities from the coast to the inland are setting their sights on the strategic fulcrum of building a “double cycle”. What opportunities and challenges will emerge in this? On May 22, 2021 International Gateway Hub City Development Forum and Peking University National Development Research Institute (Chengdu) Forum were held in Chengdu. Huang Zhuo, Assistant Dean of Peking University National Development Research Institute and Deputy Director of Peking University Digital Finance Research Center, Chengdu Supply Chain Secretary-General Wang Zhichao, Dai Deliang, West China Managing Director Zhang Yupeng, and Jiwei IoT Senior Vice President Chen Yuan discussed the opportunities and challenges of the new fulcrum of the “dual cycle”. Chinese cities usher in a period of development opportunities The “dual cycle” new development pattern is a very big opportunity for the Chinese economy. Especially in the past 2020, benefiting from a complete industrial chain and a stable supply chain, the Chinese economy has played a decisive role in the global economic recovery. At the forum, Huang Zhuo gave a set of statistics. In just ten years from 2010 to 2020, the proportion of Chinese companies in the world’s top 500 companies has increased from 54 in 2010 to 138 in 2020, which has surpassed that of the United States. 121 companies, “This shows that Chinese companies are at a new level in supply chain building.” At present, the importance of Chinese companies in the global economic system continues to increase, and they are accelerating their movement to the upstream of the industrial chain. Many companies have shown higher and higher right of speech and pricing power in their respective industries. From this perspective, “the new development pattern of the “double cycle” means a new stage of development for China. It is also a very broad opportunity for Chinese cities.” Huang Zhuo said. Take Chengdu as an example. In recent years, Chengdu has developed strong momentum. It has two major hubs, aviation and railway, covering more than 130 countries and regions. At the same time, it has a complete range of industries, including two trillion-level industries and five five-hundred billion-level industries. Wang Zhichao believes that this has played a key role in supporting Chengdu’s comprehensive and in-depth participation in the global division of labor and trade. In addition, Chengdu has a relatively high level of openness. The comprehensive bonded zone has ranked first in the country for three consecutive years. Especially during the epidemic last year, Chengdu’s foreign trade processing enterprises took on many transfer orders from inland areas. Through the construction of 66 industrial function zones and 14 industrial ecosystems, Wang Zhichao said, “Chengdu is expected to become an important fulcrum of the global supply chain in the historical opportunity period of the’double cycle’.” Regarding the development opportunities of the industrial chain in the western region in the future, Chang Yupeng suggested that we can learn from the successful experience of the “rail transportation industry chain”, apply the “Chengyu model”, attract the world’s top technology and talents, integrate the global industry chain and resources, and establish a joint venture company . Drive the optimization and upgrading of the industrial chain in the western region with a market-oriented model. Accelerate the digital transformation of supply chain enterprises Under the new pattern of “dual cycle”, opportunities must outweigh the challenges, but they will also face problems such as weak competitiveness of small and medium-sized enterprises. Chen Yuan pointed out that how to help small and medium-sized enterprises cope with difficulties is something that requires everyone to work together and consider. A local company in Chengdu, Jiwei Internet of Things, is an online platform that focuses on the digital transformation of service supply chain companies. “In the double cycle, what we have to do is how to help companies get through the supply chain. The core is to solve the connection between the company and the company. In the process of connecting, our job is to integrate the resources between the company and the company. The entire supply chain, including transportation, warehousing, processing, distribution, etc., is connected through online platforms to empower traditional enterprises, especially small and medium-sized enterprises, and help them grow together.” Chen Yuan said. As Huang Zhuo said, the construction of China’s supply chain is currently at a new stage, and the first challenge it faces is to improve the digital level of the supply chain. First of all, companies must have the awareness of digital transformation and upgrading, and on this basis, continuously improve their digital transformation and upgrading capabilities; secondly, from the government’s point of view, they must pay close attention to some bottlenecks in the supply chain, such as some In terms of the neck-stuck, the government needs to strengthen the construction of digital infrastructure and coordinate some resources to conduct concentrated research, including but not limited to the introduction and training of high-end talents. Wang Zhichao took Chengdu as an example. As early as 2017, the Chengdu Port Logistics Office established the Supply Chain Association. After that, the Chengdu Municipal Party Committee and Municipal Government successively issued a series of precise support policies, such as investing 50 million yuan in support and Support the development of Chengdu supply chain projects. At the same time, under the initiative of the Logistics Office, the Chengdu Municipal Education Bureau and the Human Resources and Social Security Bureau also jointly established the Supply Chain Industry Steering Committee, with the goal of better achieving the integrated development of talents and industries. From the perspective of financial support for the new development pattern of “dual cycles”, Huang Zhuo also suggested that financial innovation should match the real economy, just as the supply chain needs digital transformation, and finance should also develop digital supply chain finance to realize the supply chain. The goods flow, capital flow and information flow are matched to provide better financing services for these supply chain enterprises. “Last year, the Central Bank issued a framework document for supply chain finance. The goal is to vigorously develop digital supply chain finance. This requires our financial institutions to continuously improve their digital capabilities and provide more effective financial services to the real economy.” Huang Zhuo In conclusion.

Chef Bun Lai prepares to make deep-fried cicada sushi at Fort Totten Park, Washington, USA. Photo: AFP Cooking cicadas is becoming fashionable in the US this summer, when billions of cicadas like Brood X have just emerged from the ground after 17 years of cyclical “hiding”. US authorities have warned curious people to think twice before eating this dish. On Twitter, the US Food and Drug Administration (FDA) warned: “Do not eat cicadas if you are allergic to seafood, because this insect is related to shrimp and shrimp. lobster”. The warning comes as people are sharing millions of recipes for ticks. At a park in Washington, people flocked to catch ticks after tasting deep-fried cicada sushi prepared by the hands of Bun Lai, a chef who supports the sustainable food movement. Cyclically, this year comes a time when billions of ticks have lived underground since 2004, when they were still larvae, swarm to the surface, molt, find a mate, lay eggs and die. The chirping sound of ticks is the male’s way of attracting females. Swarms of these fuzzy-winged red-eyed insects have appeared in US states such as Maryland, Pennsylvania, Virginia, Indiana and Tennessee. This year, the ticks appeared unevenly and later than usual due to cold weather conditions and heavy rain in some places. However, that does not reduce the love of enjoying dishes made from ticks.

Sun Group sponsors the complete installation of equipment for an ICU with a scale of 100 multi-purpose beds. Facing the complicated situation of the COVID-19 epidemic with the number of cases increasing rapidly in Bac Giang in recent days, Sun Group has decided to sponsor complete installation equipment for a center. Intensive resuscitation ICU with a scale of 100 multi-function beds at the Psychiatric Hospital (in Song Mai commune, Bac Giang city, Bac Giang province). All medical equipment that Sun Group sponsors for Bac Giang will comply with specific technical standards set forth by experts of Bach Mai Hospital and the working group of the Ministry of Health, in order to ensure the quality of equipment. qualified, meeting the requirements of treating severe COVID-19 patients. Accordingly, the ICU ICU will be equipped with the most modern ICU machines and equipment today, such as: Central oxygen coordinator; Compressor; Air dryer; digital portable X-ray machine; Patient monitor ≥ 5 parameters; Low pressure continuous suction machine; Cyclic dialysis machine (HD); Non-invasive hemodynamic… The time for equipment supply and installation is expected to be completed within 07 days from the date of handing over the site which is eligible for construction. With some special machines that need to be imported from abroad, the handover time may take longer, but Sun Group said it will try to push the progress as soon as possible so that the Center can be put into operation in a timely manner. treatment for critically ill COVID-19 patients. Sharing about the decision to sponsor Bac Giang at this time, Ms. Bui Thi Thanh Huong, Vice Chairman of the Board of Directors, General Director of Sun Group said: “Bac Giang is the most complicated epidemic center in the country, demanding with the support and help of the Government and the whole community to be able to overcome. Helping Bac Giang fight the epidemic is also helping the whole country to overcome the pandemic soon.” Since the beginning of the epidemic season, Sun Group has been one of the pioneering enterprises, accompanying many localities across the country in the prevention and control of COVID-19. Right from the days when Vietnam had the first COVID-19 case, Sun Group’s Van Don International Airport has pioneered to welcome back flights carrying Vietnamese citizens from the “epidemic centers” in the world. Up to now, Van Don airport has welcomed 200 rescue flights, bringing about 40,000 Vietnamese people back home and foreign experts to Vietnam to work. During the 2nd and 3rd COVID-19 epidemics, Sun Group sponsored and directly installed and constructed two large-scale field hospitals, creating a “steel shield” for Da Nang city and Da Nang city. Hai Duong, further strengthen the conditions to overcome the pandemic when these two localities become epidemic centers. In addition, this group has also actively supported the epidemic prevention and control in many provinces and cities across the country such as Hanoi, Quang Ninh, Bac Ninh, Lang Son, Tay Ninh, etc. with various forms such as monetary donations. face, donating PCR testing machines and COVID-19 test kits, as well as providing necessities for border guards and epidemic prevention work in border provinces… Thus, up to now, not to mention two field hospitals During the war in Da Nang and Hai Duong, the total cost Sun Group has supported for the prevention of COVID-19 in localities across the country is nearly 90 billion VND.

Mrs. Gerty Theresa Cori is an American Jewish biochemist. She and her husband, Carl Cori, began studying carbohydrate metabolism when they were medical students at the University of Prague. When Gerty was a child, her father had diabetes, he wished his daughter would find a way to cure the disease. Gerty did not disappoint dad. In 1947, after 30 years of hard work, she and her husband were awarded the Nobel Prize in Medicine for their discovery of glycogen transformation under the action of catalysts. Glycogen is a derivative of glucose that is dissolved and re-synthesized in the body for use as an energy source and storehouse. She was born in Prague in the Austro-Hungarian Empire (now the Czech Republic) into a Jewish family. She is the eldest of three daughters of the grandparents Martha and Otto Radnitz, the manager of a sugar mill. She received tutoring at home and then went to a girls’ high school. Her uncle, a professor of pediatrics, encouraged her to pursue medicine and in 1914 she was admitted to Charles University in Prague. At that time, there were very few female students. While studying here, she met Carl Ferdinand Cori. Both have interests in laboratory research. The couple went home in 1920. That same year they got a Ph.D. in Medicine from the University of Prague. Both gave birth to a son. Mrs. Gerty Theresa Cori Carl moves to Vienna where Gerty works in a children’s hospital and Carl works in a university laboratory. As a result of the war, food was scarce for the people of Europe at that time. Gerty was given supplements at the hospital, but she turned it down because she felt the patient needed them more. She contracted xerophthalmia, a disease related to a lack of vitamins. This combined with increased anti-Semitism caused the Cori family to decide to emigrate. Together they moved to the US and worked at the Roswell Park Cancer Research Institute in Buffalo, New York. After a long time together, they naturalized the United States in 1928 and continued their studies to serve mankind. The Cori and his wife published 50 essays together while working at the Roswell Institute. Those who do most of the research should put their names first (those who do less, put their names behind) in that essay. Mrs. Gerty has published 11 separate essays. In 1929, they both proposed a theory called “Cori cycle”, which explains the movement of energy in the body: From tissue, muscle to liver and back to tissue, muscle. The Cori cycle is the explanation for the movement of energy in the body. Glycogen in muscles is converted to sugar (glucose) when energy is needed to provide physical activity, but muscles leave some sugar in the form of lactic acid for later use. Lactic acid is recycled by the liver into glycogen, which is then stored in muscles until needed. Their discovery of this process is particularly useful for the treatment of diabetes but this is also the first time that the cycle of carbohydrates in the human body is fully understood and explained. This theory subsequently earned them the Nobel Prize for Medicine. Integrity, courage and professionalism She and her husband left the Roswell Institute after publishing research on carbohydrate metabolism. They have received numerous awards for their isolation and discovery of the compound glucose-1 phosphate (later known as the Cori ester). Many universities invited Mr. Carl to work but rejected Mrs. Gerty. In 1931 they moved to St. Louis, Missouri, where Carl was offered a job as professor of pharmacology at the University of Washington School of Medicine. Although he specializes in research, Gerty is only invited to be a research assistant. In 1947, when Carl became Head of the Department of Biochemistry, Gety was promoted to professor, a position she assumed until her death. The Cori couple in the laboratory at the University of Washington In 1952, US President Harry S. Truman appointed her to the National Science Council. Dr. Gerty has received many honors and awards throughout his life, notably the Squibb Prize for Endocrinology in 1947; the National Journalism Prize for Women in 1948; National Academy of Sciences Sugar Research Prize 1950 … She received honorary degrees from the schools: Smith College, Yale University and the University of Rochester. In the summer of 1947, she began to feel symptoms of Myelofibrosis, a rare bone marrow disease. For 10 years, she continued her work, endured pain and refused to stop working in the laboratory. On October 26, 1957, she died of kidney failure. Renowned announcer Edward R. Murrow has praised her dedication, wisdom, integrity, courage and professionalism in the pursuit of medicine and biochemistry. Her image was also honored to appear on US postage stamps in 2008. The Cori Hole on the Moon is named after her. She also shares a “star” with her husband on St. Avenue of Fame. Louis.

Research on rain forecast with a forecast term of 10 – 90 days is a topic that Dr. Bui Minh Tuan (born in 1988) cherished during his master’s years at the University of Natural Sciences. “Rain is an extremely important factor for the development of most countries in the world, including Vietnam. If the rainfall is too heavy, it can lead to flooding, causing serious damage to people and material; But too little rainfall can cause droughts, lack of water for domestic use and destroy crops. Therefore, rain forecasting is always the top concern of meteorologists in the world, ”said Tuan. Although the meteorological industry in recent years has seen a strong development; weather forecasts for 5 days have the same accuracy as the one-day forecast of 30 years ago; … however, according to Mr. Tuan, this does not mean that in the next 30 years, the forecast will be 5 times more accurate than current. “There are big obstacles that the meteorological industry has not been able to overcome. Technically, the computer can help to make forecast bulletins that come monthly or longer, however, the reliability of the forecast report will drop very quickly after 5-7 days ”, said Tuan. . Currently, the theoretical foundations for short-term forecasting (from 1-5 days) have been gradually being finalized. Therefore, the weather forecast for this time period is relatively good. However, atmospheric changes on a longer time scale (from 10 to 90 days) are not fully understood. This is also one of the main reasons why the forecast is not reliable at this time. Those concerns have prompted Mr. Tuan to find laws related to the change of rain from 10 to 90 days, towards expanding the ability to forecast. Continuously from 2013 – 2019, Mr. Tuan went to “decode” the questions: Rain in Vietnam has cyclical fluctuations, especially the 10 – 90 day cycle or not? Are these variations between climatic regions? If rain in Vietnam has a strong fluctuation in a cycle of 10 – 90 days, which large-scale processes lead to the fluctuation of these cycles?, … To answer those questions, Tuan said it took him a year to read and understand the algorithms and build computational programs for large atmospheric data sets over the course of 30 years, in the period since 1980. – 2010. “These are complex algorithms, requiring high programming skills. But due to the lack of support from IT specialists, I encountered many difficulties in handling this problem ”. After the computational results have been obtained, analyzing the physical process based on those results is also a challenge. The reason is that Vietnam’s climate is very complicated, affected by many large circulation systems and has strong differentiation between regions. The characteristics of rain and the mechanism of precipitation in Vietnam still cause a lot of controversy in the meteorological community. Therefore, the selection of important aspects for analysis also requires a lot of time. Mr. Tuan also took another year to analyze all the results. What he collected during this time helped find the oscillation pattern of rain. The physical mechanisms involved in this volatility have also been shown. In particular, he also found a relationship of this oscillation with the occurrence of heavy rains in Vietnam. This brings a lot of value, because heavy rains are considered anomalous and difficult to predict. Tuan’s research is an important theoretical basis to expand the ability to predict rain and heavy rain from 10-25 days. Thanks to these results, by early 2019, his article was published in the Journal of Climate – a climate magazine of the American Meteorological Association. Mr. Tuan is a former student of Physics at the High School of Science and Technology. Because he is always curious about natural phenomena such as storms, tornadoes, thunderstorms, … he decided to enroll in the Department of Meteorology, Hydrology and Oceanography of the University of Natural Sciences, Vietnam National University. Cabinet. “When I entered school, I found Meteorology more interesting than what I thought. The ideal knowledge of mathematics and physics is quite distant, but it is applied very closely to explain natural phenomena. In addition, I also have access to modern technologies or to process data on mainframe systems. I also had the opportunity to do internships at local observatories and to participate in professional forecasting internships at the National Center for Hydrometeorological Forecasting. There, I played the role of forecasters, directly analyzing to create a forecast newsletter. It was a very wonderful experience for me ”. After graduating from university, he continued to study for masters and doctoral degrees at the University of Science. As a scientist trained in the country, Mr. Tuan assessed that in recent years, the meteorological industry in Vietnam has also had a great development. At the working place Tuan has been equipped with a supercomputer system for training and research. The latest achievements in areas such as remote sensing, data assimilation, high-performance computing, artificial intelligence, … have also been applied in weather forecasting. However, Mr. Tuan also frankly acknowledged, the support of information technology experts to maintain and operate this system well is still limited. Current researchers still have to be in charge of this additional area. Another “separate sadness”, according to Tuan, is loneliness in science. “The computer system started to exist, but for improvement, the human factor remains the prerequisite. In Vietnam today, the number of people who choose to follow the research path in this field is very small ”. The meteorology industry still seems to be “out of the general trajectory of development”, when after nearly 10 years, despite some changes, it is still slow and only motivated by a few individual individuals. There are not many people doing research in the same field, so it is very difficult to find an academic exchange. Part of the reason, according to Tuan, is that the support for young researchers is still relatively low compared to the general level of society. This is likely to lead to a crisis of high-quality human resources in the future. Currently, each training course in the Department of Meteorology of the University of Natural Sciences recruits only about 30-40 targets. While majors require people who are good at both Math, Physics or Programming, … these people often choose very few meteorology. “Right from the source of admission, this discipline has encountered difficulties. When we enroll in schools, students still know very little about the industry and only think this industry is mainly metrology, usually for the population of C because it relates to Geography. The main registration is for aspiration 2, aspiration 3, so they don’t really like and want to stick with the industry ”, said Tuan. According to the young doctor, this industry is still not respected because people still think, “rain and wind is the story of heaven”, seemingly very far away. But in fact, it greatly affects life, economy and society such as planning production activities, forecasting diseases and preventing natural disasters. “I hope in the coming time, the society will know about the Hydrometeorology industry, not only through the image of a young man in” Quiet Sa Pa “anymore. This is an interesting discipline and offers many opportunities for young people to be truly passionate about natural sciences ”.

Xi’an City Wall is now open as a scenic spot for tourist visits. Tickets are 54 yuan per person. You can climb the city wall and visit the ancient city for a week. The existing city wall is a Ming Dynasty building with a total length of 13.7 kilometers. It was built in the third year of Hongwu (1370) and completed in the eleventh year (1378) of Emperor Ming Taizu. It was built on the basis of the imperial cities of the Sui and Tang under the policy of “Wang”, which was the official city of Xi’an at that time. Later, the Ming and Qing Dynasties were repaired and added many times, and it is still well preserved. There are 8 entrance points on the city wall of Xi’an, namely, East Gate, South Gate, West Gate, North Gate, Heping Gate, Wenchang Gate, Hanguang Gate, and Shangde Gate. You can choose to buy tickets to board the city nearby. The city walls are very wide, so you can rent bicycles for cycling if you don’t want to walk. On New Year’s and holidays, there are still lights and festoons on the city wall, which is very lively. Even a marathon has been held on the city wall. There are many entertainment and tourism activities. Tourists can follow local news to go there. If you want to know more stories about the city walls of Xi’an, I recommend visiting the Hanguangmen Site Museum. This museum is open for free.
