Intangible cultural heritage is a vivid witness of the continuous inheritance of Chinese civilization for more than 5,000 years, and it is a rich nourishment for the endless development and growth of the Chinese nation. In recent years, with the goal of activating history and culture and inheriting the urban context, Luoyang adheres to the concept of "protection first, overall protection, and seeing people, things and life", deeply excavates the cultural resources of Heluo, actively promotes the integration of intangible heritage into modern life, into the culture of the times, and continues to write about Luoyang’s cultural self-confidence.

　　Have a rich family background

　　When foreign tourists come to Luoyang, the metropolis eats an authentic Luoyang water mat; Various Tang tri-colored handicrafts have long been a very representative gift in Luoyang … Do you know? Luoyang water mat making skills and Tang tri-color firing skills are intangible cultural heritage.

　　As a big city of intangible cultural heritage resources, Luoyang has eight national intangible cultural heritage representative projects, including the legend of Hutuluo, Heluo Drum, Lantern Festival (Luoyang Palace Lantern), Tang Sancai firing skills, the making skills of Luoyang water mat, the bonesetting of traditional Chinese medicine (Pingle Guo’s bonesetting method) and folk beliefs (Guan Gong’s belief in customs). Luoyang also has 62 provincial-level intangible cultural heritage projects, such as Luoyang Haishen Music, folk paper-cutting and Du Kang brewing technology, 240 municipal-level intangible cultural heritage projects and 718 county-level intangible cultural heritage projects, covering all ten categories of intangible cultural heritage list.

　　At the same time, Luoyang has 7 national, 67 provincial, 205 municipal and more than 400 county-level representative inheritors of intangible cultural heritage projects, and has initially established a directory system of national, provincial, municipal and county-level representative projects and representative inheritors.

　　At present, many non-legacy projects and non-genetic inheritors have become "golden business cards" for spreading Heluo culture.

　　Adhere to the priority of protection

　　The prosperity and development of intangible culture can not be separated from accurate classification and protection.

　　On March 1, 2017, the Regulations on the Protection of Intangible Cultural Heritage in Luoyang was promulgated, which took a key step in protecting intangible cultural heritage. Through active declaration, a number of projects such as Tang Sancai firing technology and Du Kang brewing technology have been selected into the national and provincial traditional craft revitalization catalogue. According to the Implementation Plan of Henan Traditional Skills Rescue and Protection Project and the relevant requirements of Luoyang City, a number of intangible cultural heritage projects have left valuable information through protection measures such as traditional skills rescue and protection project, traditional art rescue and protection project and digital information collection plan, which laid the foundation for subsequent online promotion.

　　In addition, Luoyang implemented the Heluo Cultural Resources Protection Project, collecting more than 170,000 clues, completing 9,946 project investigations, and collecting 1,581 registered physical materials, and more than 1,000 intangible projects were listed in the directories at all levels.

　　In recent years, 15 non-genetic inheritors have been awarded the title of "Heluo Master Craftsman" and "Heluo Craftsman" by Luoyang Municipal People’s Government, which has played a leading role as a representative inheritor and inspired the cultural confidence and mission of the non-genetic inheritors in the city.

　　Innovation, activation and inheritance

　　Just past the solar term of the awn species, the city children’s library held a special activity of 24 solar terms. Under the guidance of the teacher, the children learned about the folk customs of the solar term of the awn species, played grass fighting games, made "pastry" with ultra-light clay, and felt the agricultural activities of the solar term.

　　In recent years, Luoyang has launched 11 pilot projects of "non-legacy in campus" and "non-legacy in community", held activities such as "feeling the 24 solar terms" children’s non-legacy tour and "the rhyme of ancient capital" non-legacy in scenic spots, and promoted the normalization of brand activities of "Heluo Feihua Luoyang Non-legacy". Luoyang also relies on libraries, museums, cultural centers, etc. to set up non-legacy classes, carry out special training on cultural and ecological protection, and create a cultural atmosphere of "non-legacy participation, development and sharing with the people".

　　At the same time, Luoyang city pays attention to cross-border integration, which increases infinite possibilities for non-genetic inheritance.

　　Combining intangible cultural heritage with the research and development of cultural and creative products, we have created distinctive cultural and creative brands such as "Luoyang Gift", "Luoyang Three Colors" and "Pingle Peony Painting", and formed a number of national and provincial demonstration bases for the productive protection of intangible cultural heritage, driving 43 traditional craft intangible cultural heritage projects in the city to achieve an annual output value of over 1 billion yuan.

　　Combining the intangible heritage with the protection of ancient villages and ancient dwellings, a number of intangible heritage towns such as Aihe Town, Hand-painted Town and Bronze Town have been formed.

　　Combining non-legacy and research travel, taking non-legacy experience as an important content, we have planned and launched six excellent research travel routes and 23 research travel bases, such as "the source of civilization, rooted in Heluo", to build a research travel brand of "learning Luoyang and understanding China".

　　Combine intangible cultural heritage with consumption promotion, plan and launch the brand of cultural tourism consumption of "Eight o’clock in the evening in the ancient capital" and "New Life in the ancient capital", hold the cultural tourism consumption season of Henan Province and the fifth Heluo Cultural Grand Collection, and the exhibition of intangible cultural tourism products in Luoyang winter cultural tourism consumption season in the "Intangible Cultural Heritage Shopping Festival" to show intangible cultural heritage charm, gather cultural and creative products and set off a cultural tourism consumption boom.

Received many netizens’ contributions.

It’s really a feast for the eyes.

Not only does it look appetizing.

It also hides the feelings and stories of Weifang people

Next, I will share with you.

Pass warm and beautiful wishes

@ Hu Xiaoyuan

Whether it is a big family celebrating the New Year together or a small family of two people celebrating the New Year, reunion is a good year. The new year is better than the old year, and everything you want is what you want. Happy Chinese New Year, everyone!

@ 亵亵亵亵 radish skin

This year’s New Year’s Eve is the most neat gathering of the whole family in these years. It is really not easy for everyone to rush back from all over the country just to reunite for the New Year. It is even more joyful to have a family birthday. Year after year, customs are always advancing with the times. What remains unchanged is the good wishes and expectations for the future contained in the New Year’s Eve dinner. Life is not always calm, but at this moment, being with family, toasting and celebrating the New Year together, and filling up the sense of ceremony, this is the greatest significance of the New Year.

@ Lao Wu

Before the eve of every year, my brother always cooks a sumptuous dinner and waits for our arrival. The food is impeccable, as well as the time and mood for dinner. After they grew up and left home, those short gathering moments became the marks before the Spring Festival, and they started again and again.

We have to grow up, we have to grow old, and every year we can get together is as precious as ever. Let’s look forward to every gathering day that will come in the future!

@ Zhao Pingfan

In this year’s New Year’s Eve dinner, there are two dishes cooked by two sons themselves. Although the dishes are simple, they have witnessed their growth. Think about my parents who have worked hard for a whole year. On New Year’s Eve, they prepared a table full of delicious food for us, and my heart was full of emotion and happiness.

Say goodbye to Muir, fireworks every year, morning and evening, and peace every year. Growing up with children and growing old with parents is our life and the value and significance of our struggle. A good life needs to be down-to-earth and hard work, but now, let’s unload all the troubles and pressures and enjoy this happy dinner. In the new year, I wish the motherland prosperity, peace and prosperity! I wish you all a happy New Year and all your wishes!

Furnace furnace

In the past, the adults were busy in the kitchen, and the children were cooking in the house. Nowadays, the youngest child in the family is 18 years old. This year’s New Year’s Eve dinner included fried chicken cooked by my aunt, air-dried chicken brought by my second aunt for several hours, crispy pot made by my uncle, dried shrimps stuffed with mushrooms made by my mother, cake made by my sister, and I also heated a prepared dish for the table.

Year after year, more and more people cook New Year’s Eve dinner, and the kitchen becomes more and more crowded. The New Year’s Eve dinner cooked by the whole family is especially delicious!

@ Crispy Shark

The seasons change, the years flow, and in a blink of an eye, it is the New Year. The taste of the year always needs to be experienced by taste buds. The familiar smells are the best comfort for the heads of families to gather at the small dining table. Grandma made pig’s trotters jelly and "chicken tie" in advance, and mom fried spiced meat and lotus root two days ago, but even though the table was full of delicious food, peanuts were still grandpa’s favorite appetizer. Eating the hot New Year’s Eve dinner and watching the laughing family, I firmly believe that next year will be better.

@ Duan Xiaoting wants to struggle

Rabbit is safe, rabbit is healthy and rabbit is lucky! The past is a preface, and the future is hopeful. I wish you all a healthy new year! Happy new year! Happy new year! Mia san mia！

@ Xiao Fu Xiao Fu Go All Out

A reunion dinner, a feeling of returning home. On New Year’s Eve, with the BGM of the Spring Festival Gala and the endless firecrackers, a series of affectionate delicacies are served on the table. The unpretentious but full-fledged New Year’s Eve dinner is a family’s emotional sustenance for a year. We often say now that this year is getting stale, but I think there is always a taste of the year that we will never forget, and that is the taste of home.

@ Li Jinling

Since the morning, there has been a concerto of pots and pans in the kitchen, and the preparation of dishes for the New Year’s Eve dinner has begun. New Year’s Eve dinner is the most traditional Weifang dish, with a grand sense of ceremony. No matter how tired and hard this year is, at this moment, sitting around with my family is happy and happy.

@ 京京京京京京京京京京京京京京京

Every year’s New Year’s Eve dinner can pour a lot of expectations. It seems that after supper, this year is complete. The happiness of a family is not only to attend, but also to be in the morning and evening. 2023 warm reunion, smooth and safe.

@。 . .

On duty, I didn’t go home for two years. When I went home this year, my parents set out a good table! May the new year be better than the old year! In the new year, everyone is round and round!

@LONG

How fortunate, age goes hand in hand! Everything went well last year, and everything will go well this year. In the year of Guimao Rabbit, may everything be renewed, old diseases be healed, peace and success be achieved, and everything will win!

@ Li

The family is sitting around, and the lights are amiable. At the beginning of the new year, Vientiane is renewed. May the people you miss be safe and happy. May everything you think go your way.

@ New Year’s Eve overtime baby

Although there is no happy reunion this year, the New Year’s Eve dinner for a family of three should also be full of ceremony. Braised chicken, braised fish, beef in golden soup, vermicelli shrimp with garlic … are all wanted. I hope we can get rid of masks in the new year, be safe and happy, and win everything!

Jiang Guanghui

With the mobile phone, it records the busyness of family members, and also conveys a sense of "mission" to bid farewell to the old year and welcome the new year. After eating this New Year’s Eve dinner, everyone will move towards a "new preface" and wish everyone good luck in the Year of the Rabbit.

@wen

On the New Year’s Eve, what you eat is no longer the delicious food you look forward to for a year, but the reunion and happiness, the taste of the year and the well-being of all families.

@ Wang Jingbo

The taste of the year in memory is nothing more than the food cooked by parents! Year after year, people can’t eat enough!

Read the original text

April Day in Spring, National Science Foundation, USA（NSF）But there was a cold snap-the research funds for the new year were frozen.

Trump Administration Efficiency Department led by American entrepreneur and billionaire elon musk.（DOGE）The reason for this is to cut government spending and reduce staff. According to the latest report in Nature magazine, DOGE is reviewing the list of related research grants evaluated by NSF in February, and considering terminating more than 200 of them.

It’s not just NSF that is bleak. National institutes of health（NIH）Because of the lack of funds, some laboratories can’t even afford gloves, Petri dishes and reagents. National Oceanic and Atmospheric Administration（NOAA）, the US Food and Drug Administration（FDA）, U.S. Environmental Protection Agency（EPA）Scientists in other institutions are also facing the risk of "cooking without rice" and even being fired, and their morale is low and their work is paralyzed.

Many American scientists complain bitterly and bluntly say "feel helpless" and "the future is scary".

First, suffocating censorship

NSF, with a research budget of 9 billion dollars, is one of the largest funding institutions for basic research in the world.

However, since Trump took office as president of the United States this year, the agency has suffered a cold reception one after another: first, all funding was frozen; After that, I received a court unfreezing order in February, but I had to dismiss a large number of probation employees; At the beginning of April, the institution cut the postgraduate scholarship program by half, offering only 1,000 places instead of 2,000 in previous years.

In fact, the Republican Party of the United States has long been "disgusted" with the NSF funding method of the Democratic government. As early as during the administration of former President Biden, ted cruz was then a Republican senator from Texas and the current chairman of the Senate Science Committee.（Ted Cruz）My office once published a report that from January 2021 to April 2024, 3,483 research funds approved by NSF went to "promoting diversity, fairness and inclusiveness"（DEI）The principle of suspicious projects ",wasted $2 billion.

With the advent of the Trump 2.0 era, in February this year, NSF initiated a review of all funding, with the aim of ensuring that Trump’s executive orders on "radical and wasteful" DEI projects and "gender ideology" were not violated. Among them, there are hundreds of "sensitive words" that are thought to be related to ideology but not to hard science, such as "female", "black" and "inequality".

On April 14th, DOGE turned its attention to NSF funding again. Its staff entered the NSF headquarters building in Alexandria, Virginia, and gained access to its funding management system, and used this access to prevent the disbursement of hundreds of research funds that had been approved in the multi-step review process and only needed to be finalized.

"This makes us feel scared." An NSF project official said.

It is reported that NSF’s research proposal has to go through several steps before it is approved: first, it is submitted to NSF project officials with professional knowledge. If it passes the review, it will entrust a third-party independent expert to review it, and the success rate is usually between 20% and 30%; Next, NSF department heads approve the funds and submit them to the appropriation and agreement department for final approval. However, DOGE’s intervention made the application for funding that had already reached the last step be returned.

It is worth noting that before DOGE was established in January this year, NSF’s new research funding rate has slowed down by half compared with 2024. As of April 16, the relevant funding has completely stopped.

US White House Spokesman Kush Desai（Kush Desai）The explanation given is: "The Trump administration is committed to ensuring that federal research expenditures meet the daily needs of the American people."

However, Democrats in the US House of Representatives believe that Cruz’s report and DOGE’s practice have major defects, which will "undermine the important work of researchers, educators and institutions" and will "endanger the US economy and national security".

According to statistics, at present, more than 200 proposals have been marked as "considering termination" by DOGE. Some of these proposals were marked because they contained wording about the "wider impact" of research on society-wording that Cruz did not like. Anthony Kit, a computational biologist at the University of Wisconsin-Madison（Anthony Gitter）It was "named" by Cruz. Kit said, "Cruz believes that universities are elite gathering places, accommodating scholars who do not engage in scientific research and are out of touch with reality. But his view is out of touch with the actual situation. "

In this regard, Zoe Lofgren, a senior Democrat of the Science, Space and Technology Committee of the US House of Representatives,（Zoe Lofgren）Turaman Panchanatan, director of NSF.（Sethuraman Panchanathan）"NSF must avoid being led by the nose and being forced to accept these empty findings and undermine its own audit procedures," wrote the letter.

Second, the "strangled" science

The Trump administration in the era of 2.0 not only made NSF tremble, but also made life difficult for many national scientific research and funding institutions.

NIH is one of them. As a large national biomedical research funding institution in the United States, its subordinate laboratories also employ thousands of scientists. The biggest dilemma faced by the scientists of this institution is "running out of ammunition and food".

In February this year, the Trump administration set the consumption limit of almost all government credit cards to $1 each, which brought a disastrous blow to NIH’s laboratory-it was impossible to buy gloves, pipettes, Petri dishes, reagents, storage bottles and other basic scientific research materials. For example, a laboratory ran out of chemicals used for cryopreservation and treatment of organ donors’ brains; Another key laboratory lost half of its staff in the wave of layoffs and had to "borrow" staff from other teams to continue the work of analyzing blood samples for more than 200 clinical trials.

"NIH can’t hire people, recruit students, travel and communicate with the outside world at present … It is completely paralyzed and can’t operate normally." A chief researcher of the agency said.

The FDA of the United States was also seriously affected by the layoff plan and was forced to suspend most of its food safety testing. As of April 18, the agency’s work on bird flu testing for milk, cheese and pet food has stopped. The same is true of NOAA. Many probationary employees who have been on the job for less than two years were fired first, then re-employed, and then placed on administrative leave, because their jobs were in jeopardy and people were worried.

Other actions of the Trump administration are also "overweight" the difficulties faced by scientists. NIH researcher strait Fowood(alias Straight Forward)It is said that Trump administration officials will put forward various "wonderful" requirements: such as collecting the list of all contract workers and issuing an ultimatum. If they fail to reply within 24 hours, they will be dismissed. "These endless demands are killing the function of a scientific research institution with red tape." Fowood said.

In addition, the Trump administration has also cut research funding for research projects such as vaccines and climate science, and the upcoming new round of layoffs has aggravated the current turmoil. "Everyone is working hard, but morale is really low." Fowood said.

The EPA has always been the target of the Trump administration, and it is forbidden to track the greenhouse gas emission reduction of clean energy technology projects. Those high-emission enterprises can apply for "presidential exemption" and are no longer bound by pollution regulations. This makes many employees lose confidence. An EPA employee bluntly said: "I like this job very much, but the actions of the federal government make EPA no longer a place where people want to work."

"In the past, the federal science policy was’ not perfect’, but before Trump took office, some reforms might be welcomed. But now, the government is’ destroying everything’ … We are constantly bombarded by a large number of arbitrary administrative instructions. " The aforementioned NIH chief researcher bluntly said.

Third, who wins and loses in the "tug-of-war"

Observers believe that the Trump administration’s new round of cold current of science and technology policy has not yet ended. For example, according to Washington post, the White House’s upcoming draft budget for fiscal year 2026 plans to cut 40% of NIH’s current budget of $47.4 billion, merge the original 27 institutes into eight, and cancel the Institute of Nursing and Minority Health. Therefore, the current American scientific community is still far from welcoming the coldest moment.

Many people believe that Trump’s intervention in the American scientific research system is not a temporary rise, but a continuation of his policy philosophy in the 1.0 era. At that time, Trump called climate change a "scam", repeatedly tried to cut the budgets of EPA and NIH, and appointed Scott Prut who had sued EPA.（Scott Pruitt）As the director.

Today, this kind of intervention is not only continuing, but also a systematic implementation path-"2025 Plan".（Project 2025）.

This plan was released by the Heritage Foundation of the Republican Party in April 2023. It is a 922-page "policy blueprint" aimed at providing detailed policy recommendations for the Trump 2.0 era.

Previously, the policy recommendations in the plan, including banning abortion, reforming the federal government and cutting funds for climate science, had aroused strong public opposition. Trump claimed not to know about the plan during the presidential campaign. However, according to the Wall Street Journal, more than half of Trump’s executive orders are consistent with the recommendations of the "2025 Plan", and most of the 40 authors listed in the plan are key figures in the Trump administration, and six of them are even nominated by Trump as cabinet members.

The "2025 Plan" defines many science-related policies. These include anti-diversification efforts, such as "canceling policies and procedures that promote gender, race and equality initiatives under the banner of science" and "canceling funding for climate science and green energy" on page 60; Cut university funds, such as "Congress should limit the indirect expenses paid to universities" on page 355; Reduce the size of the government, such as "permanently and substantially reduce the number of non-defense federal employees" on page 78.

The analysis of Nature magazine shows that the Trump administration is considering implementing some other suggestions in the "2025 Plan", including prohibiting fetal tissue research and canceling or greatly reducing the number of visas issued to foreign students. The analysis also shows that the Trump administration’s executive orders are not always consistent with the plan, and in many cases, even more extreme practices have been taken than the plan.

These political interventions make the American scientific community uneasy. At the end of March, about 1,900 members of the National Academy of Sciences, the Academy of Engineering and the Medical College from more than 400 universities and research institutions in 38 States issued a joint open letter, pointing out: "At present, the American scientific community is shrouded in an atmosphere of terror … The Trump administration is dealing a heavy blow to the scientific cause of the United States by cutting research funds, dismissing scientists, revoking the public’s access to scientific data, and forcing researchers to change or give up their jobs for ideological reasons."

Some opposition voices have also entered the judicial process. For example, in mid-April, the American Education Research Association and the Education Effect Research Association jointly filed a lawsuit in the Federal District Court of Maryland, demanding the restoration of scientific research funds and personnel allocation. In February this year, the attorneys general of 22 States in the United States filed a joint lawsuit against the Trump administration for cutting research funding in the medical and public health fields.

However, there are also many scientists who take a wait-and-see attitude towards the behavior of the Trump administration. Sasha gusev, a statistical geneticist at the Dana Farber Cancer Institute in Boston.（Sasha Gusev）It is believed that it may also contain reform opportunities, such as the reform of NIH structure and the reflection on the funding process, which will help to improve the efficiency of its capital use and the diversity of recipients. However, he also stressed that the reform should be optimized based on the existing system, rather than completely overthrown. If the strategy of "burning it and rebuilding it" is adopted, NIH, which is regarded as the "global biomedical laurel", may be hit.

Despite the persistent doubts, the Trump administration’s pace of scientific funding cuts and layoffs has not slowed down. Michael Loubere, physicist and researcher of science and technology policy at new york City University.（Michael Lubell）It is believed that the American scientific community is facing an unprecedented "uncertainty tug-of-war": "Some fields will become winners, such as the direction supported by Trump and Musk; However, under the premise of tight federal budget, there are also doomed losers. "

　　CCTV News:Recently, many major foreign trade provinces are taking active actions to help enterprises "integrate" their domestic and foreign trade. A few days ago, the Shanghai Municipal Commission of Commerce held an offline "matchmaking meeting for e-commerce to help foreign trade expand domestic sales".

　　At 9 o’clock in the morning, there are still 45 minutes before the matchmaking meeting. Sixteen major domestic e-commerce platforms and nearly 80 foreign trade enterprises have come to sign in one after another.

　　Chen Duan, the person in charge of the enterprise, said that they have a relatively large share in the United States, and it is the first time to connect with some domestic e-commerce platforms and international e-commerce platforms. It is not easy for anything to go from 0 to 1, but there is at least one hope that we can still see opportunities in the crisis.

　　At 9: 45, the matchmaking meeting officially began. On the one hand, it is the policy presentation of the Shanghai Municipal Commission of Commerce and major e-commerce platforms, and on the other hand, it directly sets up a docking negotiation booth. Many e-commerce companies have long queues in the front row.

　　At the fair, Lu Yan, a post-90s foreign trader, came with a bag full of samples and product catalogues. In front of the e-commerce booth, she demonstrated the function of vacuumized fresh-keeping bag products, and on the other hand, she was still calling to arrange factory delivery.

　　On the table of the e-commerce platform, in addition to the famous brand that says "foreign trade boutique, welcome home", there is also a "two-dimensional code", and foreign trade enterprises can directly scan the code to settle in.

　　In the Shanghai Federation of Industry and Commerce, Chinese and foreign law firms and chambers of commerce, the activity of "Foreign Trade Excellent Products in China" was launched, and the direct service for foreign trade enterprises to expand domestic sales was opened.

　　Rola Chen, Secretary-General of the Industrial Products Service Chamber of Shanghai Federation of Industry and Commerce, said that industrial foreign trade enterprises whose exports to the United States are blocked can quickly enter the industrial products e-commerce service platform through platform links.

　　Various districts in Shanghai have also launched a series of measures to actively help foreign trade enterprises expand the domestic market by building an online and offline linkage platform for "integration" of domestic and foreign trade.

　　Zhao Lantian, deputy director of the Jing ‘an District Commercial Committee of Shanghai, said that the domestic market is a large-scale consumer market, and it is growing day by day. Help enterprises to do accurate docking, reduce the cost of domestic sales as much as possible, and support the smooth transformation of foreign trade enterprises.

　　Shanghai foreign trader: "We always have a way."

　　At the matchmaking meeting, a foreign trader in the textile industry said, "Our company has been specialized in foreign trade for more than 20 years, and no matter how difficult the situation is, we must find ‘ New way ’ There is always a way. "

　　This tenacity and persistence are precisely the characteristics of China’s foreign trade. Just as the General Administration of Customs said when it released the foreign trade data in the first quarter: At present, China’s exports are indeed facing a complicated and severe external situation, but "the sky will not fall".

　　At today’s "1+1" series press conference on "Ten Years of Education", the Department of Science, Technology and Information Technology of the Ministry of Education said that since the 18th National Congress of the Communist Party of China, the Ministry of Education has successively issued and implemented the 12th Five-Year Plan for the development of science and technology in institutions of higher learning, and organized and implemented a number of major actions such as the plan for improving innovation ability, the independent innovation action in key areas and the plan for basic research on Mount Everest. The ability of scientific and technological innovation in colleges and universities has been greatly improved, the reform of system and mechanism has been continuously deepened, and remarkable results have been achieved in serving the major needs of the country, which has made irreplaceable and important contributions to the construction of an innovative country and a powerful country in education and science and technology.

　　The ranks of scientific and technological talents have grown stronger.. In the past ten years, the group of strategic scientists and leading talents in colleges and universities has grown steadily. More than 40% academicians of the two academies and nearly 70% winners of the National Science Fund for Distinguished Young Scholars have gathered in colleges and universities. Cultivating high-quality innovative talents through high-level scientific research has supported the training of millions of master’s and doctoral students.

　　Scientific and technological innovation resourcesspeed upassemble.In the past ten years, the R&D (research and development) funds in colleges and universities have increased from 76.87 billion yuan in 2012 to 159.2 billion yuan in 2021, and the total amount of funds allocated in the past ten years has reached trillions. The funds entrusted by enterprises and institutions increased from 39.18 billion yuan in 2012 to 84.75 billion yuan in 2021, an increase of over 116%. The full-time equivalent of R&D personnel in scientific and technological activities in colleges and universities has increased from 209,000 person-years in 2012 to 334,000 person-years in 2021, an increase of nearly 60%.

　　The innovation platform system is more perfect.In the past ten years, universities have taken the lead in building more than 60% of the state key laboratories of disciplines and 30% of the national engineering (technology) research centers; Aiming at the forefront of science and technology in the world and the major needs of the country, the Ministry of Education has actively laid out and built 25 frontier science centers, 14 platforms for tackling key problems in key areas, 38 national-level collaborative innovation centers, and more than 1,500 platforms such as key laboratories of the Ministry of Education, engineering research centers and collaborative innovation centers jointly built by provinces and ministries.

　　The contribution of scientific and technological innovation is more significant.In the past ten years, colleges and universities have won 6 out of all 10 national natural science first prizes, accounting for 67% of all natural science prizes, and have won the national natural science first prizes in recent three years, which is a veritable main force in basic research. In the past ten years, colleges and universities have won 10 of all 11 first prizes for national technological inventions, 72% of all technological inventions, and two special prizes for national scientific and technological progress, becoming the source of major scientific and technological breakthroughs.

　　The ability to transform results has been significantly improved.In the past ten years, the number of patents granted in colleges and universities has increased from 69,000 to 308,000, an increase of 346.4%, and the authorization rate has increased from 65.1% to 83.9%. The number of patent transfer and licensing contracts has increased from more than 2,000 to 15,000, and the amount of patent conversion has increased from 820 million yuan to 8.89 billion yuan, an increase of nearly 10 times, which has not only achieved quantitative growth, but also achieved qualitative improvement, transforming more scientific and technological achievements into real productive forces.

　　International scientific and technological cooperation is more extensive..

Huawei P series has always been favored by the market for its image function. Under the background of "one machine is hard to find" in Mate 60 series, consumers have high expectations for the brand-new P series, and even there is a phenomenon of "blind ordering".

On April 15th, Huawei officially announced the brand upgrade of P-series and renewed it as Huawei Pura. This move indicates that P-series will not only continue its position in the high-end market, but also keep pace with Mate series with a new image and positioning to jointly build Huawei’s dual flagship pattern in the high-end market. The change of brand name "Pura" symbolizes the pure pursuit and technological innovation of P series in the field of imaging, and also shows the market that it opens a new era of mobile imaging and scientific aesthetics.

Today, we are the first to experience the big cup in Pura 70 series-PURA 70 Pro+. This product undoubtedly carries Huawei’s commitment to the ultimate image experience, as well as all-round improvement in design, performance and innovative functions. Below, let’s take a look at the upgrades and actual performance of Pura 70 Pro+.

First of all, it is the basic parameters of Huawei Pura 70 Pro+, which helps you to understand this model quickly.

According to the official description, as Huawei Pura,The first product of the series,Huawei Pura 70 Pro+Don’t stick to itIn the past, the perceptual cognition of the beauty of nature pursued the beauty of the rational order of modernism.

Specifically,In terms of appearance, Huawei Pura 70 Pro+ boldly broke through the shackles of most conventional geometric elements such as squares and circles, and skillfully integrated three-dimensional geometric lines with precision image modules to create a unique weather vane design. This design not only gives the mobile phone a distinct recognition, but also builds a brand-new family design language of Pura series, leading the future mobile phone aesthetic trend with a forward-looking perspective.

Specifically,Huawei Pura 70 Pro+The upper left corner of the fuselage is designed by "wind vane"Lens module,The lens configuration is super wide-angle lens, periscope telephoto lens and super spotlight main camera from top to bottom.

existPura 70 Pro+On the front, it is a 6.8-inch quad screen with equal depth, which supports FHD+ resolution, that is, 2844×1260 pixels, with 1.07 billion color display and P3 wide color gamut, ensuring the richness and accuracy of colors. In addition, the screen adopts LTPO adaptive refresh rate technology of 1-120Hz to ensure a smooth viewing experience, while high-frequency PWM dimming of 1440Hz and touch sampling rate of 300Hz further improve the comfort of the screen. In addition, the use of Xuanwu toughened Kunlun glass material provides the screen with extremely high scratch resistance and drop resistance.

In the design of the side of the mobile phone,Pura 70 Pro+The bottom of the is equipped with dual nano SIM card slots, a Type-C interface supporting USB 3.1 Gen1 standard and speakers. The right side of the fuselage is equipped with a volume adjustment button and a power button, while the top is equipped with an infrared sensor and a noise reduction microphone.

As for the color matching of the fuselage, in addition to this "light woven silver" in my hand,Pura 70 Pro+There are also "String White" and "Phantom Black" to choose from.

In terms of feel,Pura 70Pro+ uses a four-sided micro-curved screen design, which is actually quite large. Thanks to the body width of 75.1mm, compared with Mate60 series, the improvement in hand feel is quite obvious. The second generation of Kunlun glass, coupled with the injection of basalt tempering technology, further improved the ability of mobile phones in wear resistance and drop resistance.

The image part isHuawei Pura 70 Pro+ is the core selling point, and Huawei Pura 70 Pro+ is equipped with a new generation of ultra-spotlight imaging system.

The main camera has a 1/F1.4-inch outsole sensor, which is equipped with the largest physical aperture in the industry at present, bringing a large amount of light.

The telephoto is a 48-megapixel super-focusing macro lens, and the aperture is also current.F2.1 with the largest telephoto in the industry,The large light input can improve the shutter speed and bring clear image quality to telephoto flash.

We also useHuawei Pura 70 Pro+ had a real shooting experience:

Judging from the proofs,Three lenses of Pura 70 Pro+Whether in indoor, outdoor or dark environment, the film has good color performance, and the wide dynamic range makes the details of highlights and shadows fully preserved, avoiding overexposure or underexposure.

In addition to the regular shooting, this timePura 70 Pro+ also has a great experience in capturing pictures. It is understood that HuaweiPura 70 Pro+Hyper-spotlight image system and XDMotion motion engine realize motion blur restoration technology. This means that when shooting fast moving objects, the mobile phone can perform real-time double exposure operation through the sensor: a short exposure captures the clear details of the action and a long exposure records the rich information of the background. AI technology then analyzes and matches the features of the two exposed photos to eliminate the blur and synthesize a clear high-definition image to ensure that every dynamic moment can be accurately captured. Whether it’s capturing a car in the distance, the instantaneous action on the court or the lively posture of a pet at home, it can be easily frozen to ensure that users will not miss any wonderful moments.

In terms of performance,Huawei Pura 70 Pro+Equipped with a brand-new Kirin chip, with 16GB of large memory, and then blessed by the game engine, I believe the experience in the game will be very good. And in order to verifyThe experience of Pura 70 Pro+ in games has also been tested:

With the performance mode turned on, the screen refresh rate set to smart, and the screen resolution set to smart, PerfDog was used for two rounds of game testing.

In "In the test, we set the game screen to high frame rate+extreme image quality, which was tested in a single game.Huawei Pura 70 Pro+The frame rate can be stabilized at the level of 120 frames. The only frame lock is that after the character dies, the mobile phone reduces the game frame rate to 60 frames to reduce power consumption, and the frame rate is immediately pulled back to 120 frames after the character is resurrected.

We also tested Protogod, which requires higher performance. The game screen is set to extremely high quality +60 frames, and the game acceleration function is turned off. The average frame rate of the 30-minute running map in Sumeru City is 60.3 frames, and the overall experience is relatively smooth.

Finally, we also tested the endurance performance of Huawei Pura 70 Pro+. Huawei Pura 70 Pro+ has a battery capacity of 5050mAh and supports 100W wired super fast charging and 80W wireless super fast charging.

According to the actual measurement, after 5 hours of heavy endurance test, Huawei Pura 70 Pro+ has 49% remaining, and the power of Pura 70 Pro+ can be charged from 1% to 100% in 30 minutes with 100W wired fast charging, and the results are still relatively excellent.

On the system side, Huawei Pura 70 Pro+ is equipped with HarmonyOS 4.2 operating system. Among all the experience upgrades, my favorite is five new interactive themes. These five themes can support eye-following interaction and click interaction. For example, the theme of "interesting scene" can hit the ball back and forth with the movement of the eye gaze area, which is very interesting.

In terms of security function, HarmonyOS 4.2 introduced a floor-level device search function to accurately locate the specific floor of the lost device and help users quickly retrieve their mobile phones.

In addition, HarmonyOS 4.2 can control the application to obtain the authority of the device direction, so as to intercept the jump of the shake advertisement, make the user’s experience in the application more pure, and further improve the purity ability of HarmonyOS.

When it comes to satellite communication technology on mobile phones, people will naturally think of Huawei. It can be said that Huawei has played a vital role in promoting the popularization of mobile satellite communication technology.

This time, Huawei Pura 70 Pro+ is equipped with dual-satellite communication. In the case of no network emergency, it can communicate with the outside world through Tiantong satellite communication and Beidou satellite message to protect users’ travel safety. In addition, Pura 70 Pro+ also supports sending Beidou satellite image messages, and the sent messages can be edited freely, so that the sender can convey the information that needs to be expressed more accurately and efficiently when there is no terrestrial network.

In addition to satellite communication, mobile phone signal is also Huawei’s advantage. Pura 70 Pro+ adopts Linxi communication technology, and through the strong combination of Linxi antenna and AI algorithm, it can provide stable and reliable communication experience in high-speed rail, subway and basement.

Generally speaking, Huawei Pura 70 Pro+ has brought us a comprehensive experience upgrade in design, image, communication and performance, and alsoUndoubtedly, it will lead the new trend of the mobile phone industry and bring more rich and wonderful experiences to users.The choice to release Pura 70 series on the anniversary of Ascend P1′ s listing highlights Huawei’s attention and expectation for P series, which indicates that a new era of Huawei in the field of mobile imaging and technology aesthetics has begun.

　　Guangzhou Daily News (all-media reporter Ren Shanshan correspondent Yu Guangbiao) The hoarse voice has not improved for more than a month, not necessarily "getting angry", but more likely laryngeal cancer! If you smoke for a long time, you should be more alert to the risk of laryngeal cancer.

　　Recently, the first member congress of the professional committee of laryngopharyngeal cancer of Guangdong Clinical Medical Association and the second standardized diagnosis, treatment and new progress course of laryngeal and laryngopharyngeal cancer were held in Guangzhou. Professor Liu Xuekui, Chairman of the Professional Committee of Laryngolaryngeal Tumors of Guangdong Clinical Medical Association and Head and Neck Surgery of Cancer Prevention Center of Sun Yat-sen University, pointed out that in recent years, the incidence of laryngeal cancer has shown an increasing trend, ranking second among all head and neck tumors, and the incidence has shown a younger trend. He reminded that men who have a history of smoking and are over 40 years old should see a doctor as soon as possible and have an electronic laryngoscope examination once they have hoarseness for more than a month frequently, or if the heat-clearing and anti-inflammatory treatment according to pharyngitis does not work.

　　Liu Xuekui pointed out that the 5-year survival rate of early treatment of laryngeal cancer can reach more than 90%, and once it is diagnosed in the advanced stage, the survival rate will drop sharply. "Like many cancers, in China, when many patients with laryngeal cancer are diagnosed, they often reach the middle and late stage, and the treatment of advanced laryngeal cancer is still a problem." He reminded that patients with suspicious symptoms of laryngeal cancer should be examined by electronic laryngoscope. The examination cost of electronic laryngoscope is not high, and it is very convenient. Once you see a suspicious tumor in the throat, the doctor takes a sample for pathological examination, which is conducive to the early diagnosis.

　　At present, the clinical treatment methods for laryngeal cancer mainly include radiotherapy, surgical treatment, comprehensive treatment of radiotherapy and surgery. Generally speaking, the treatment of early laryngeal cancer is mainly surgery and radiotherapy, and comprehensive treatment is needed in the middle and late stage.

　　The traditional treatment mode of locally advanced laryngeal cancer is total laryngectomy plus postoperative radiotherapy, and the lesion is completely removed. The survival situation of patients is still optimistic. However, under this treatment mode, the function of larynx is often seriously damaged or even unable to be preserved, which affects the respiratory function and vocal function of patients and leads to poor quality of life.

　　In recent years, with the medical profession paying more and more attention to the quality of life of cancer patients, some doctors have proposed that the laryngeal function should be preserved as much as possible in the treatment of advanced laryngeal cancer, and radiotherapy and chemotherapy should be carried out first, and then surgical resection should be carried out if the effect is not good or the disease recurs.

　　Liu Xuekui pointed out that it is important to preserve laryngeal function, but it is more important to save the patient’s life first. Clinical practice shows that radiotherapy and chemotherapy are difficult to achieve good results in a considerable number of patients with laryngeal cancer. Under the treatment idea of "preserving function first", patients may miss the best opportunity for surgical resection and eventually fail to operate. "It is equivalent to that if the scheme of radiotherapy first and then surgery is not effective, the previous radiotherapy and chemotherapy will be wasted, and the radiotherapy and chemotherapy after surgery will be ‘ Remedy ’ The opportunity is also lost. " He believes that when deciding the treatment plan, doctors need to make careful choices, depending on the specific situation of patients.

　　It is worth mentioning that in recent years, Liu Xuekui innovatively used titanium mesh stent to reconstruct laryngeal function, which provided another safer, more reliable and economical treatment method for patients and brought good news to patients. At present, this new technology has won the national invention patent and has been adopted by many hospitals in China.

　　The topic we are talking about today, which I believe all the players know, is a common phenomenon in billiards culture at present ── gambling, commonly known as hanging rod and playing net.

　　The following are the questions that most golfers often ask me. Let’s discuss this question from the following angles:

　　one

　　Can gambling contribute to the growth of football skills?

　　Many players believe that training psychological skills can only be strengthened through gambling! ! !

　　Is this view really correct? ? ?

　　AnsSports psychology can be divided into several parts: too nervous, not excited enough, concentration, self-confidence, etc. Therefore, gambling only provides a tense environment for you, but how to overcome the nervous mood and show the best sports performance?

　　The most scientific way is to train through sports psychology. Only in this way can we really overcome the nervous mood and prescribe the right medicine instead of gambling!

　　2

　　In today’s billiards environment, players don’t gamble.

　　How to live?

　　Many golfers told me that in today’s billiards environment, players can’t make money, and gambling is their source of income! ! !

　　Is that really the case? ? ?

　　AnsAs far as I know, the current population of billiards is the largest among all sports in China. This also means that billiards has a broad market base in China. However, the players’ income source is unstable. Is it their own problem or the market problem?

　　After their own achievements, how many players can really promote the good side of billiards?

　　I have been a coach in the mainland for five years. There are a large number of people who want to learn billiards, but most of them don’t know where to have a good learning environment.

　　I believe that there are a lot of players everywhere. If everyone is willing to promote billiards, go deep into schools and communities, and carry out standardized teaching and training, will there be no stable source for players?

　　I also give you a suggestion. After all, among the people who learn billiards, only a few can reach the world level. Therefore, teaching should focus on mass groups, respond to national fitness, and the fees should not be too high, so that more friends who are interested in billiards can really participate. After the base number is much, we should look for suitable seedlings and cultivate them so as not to put the cart before the horse. Only after the mass base is established can it bring a bigger market, so that billiards can create a better vision. Imagine, the number of people who are interested in billiards has increased, and which market will not be able to do, such as ball room, ball equipment and teaching?

　　three

　　What is the influence of gambling on values?

　　AnsI believe all my friends who know me know that I forbid my students to gamble, especially gambling with excessive amount, which is absolutely forbidden in Taojiaban.

　　Why do I want to ban it repeatedly? Let’s discuss it from several points of view.

　　 1. Impact on the competition:

　　Many players gamble privately, and the amount is not low. It is possible that they will win tens of thousands of yuan in gambling after a game. But the game! You may have to win more than ten games to get the corresponding bonus. Over time, when you encounter setbacks in the game, you will unconsciously have the idea of giving up, and the subconscious will appear "Why am I so tired? Anyway, I will have a gamble". Is it not harmful to the game?

　　 2. Post-gambling group:

　　In my opinion, many players have become addicted to gambling and have gradually changed from gambling to gambling. I have seen a lot of players, and the bonus is not enough for him to lose, but he owes a debt. When you are used to money coming and going quickly, what are your values about money? Once you are addicted to gambling, you can’t keep money, and spending money will become extravagant, and in the end you will be left with a debt. Imagine that when the player comes to this point, will he still want to engage in his hard-working billiards career?

　　3, the perception of society:

　　After the efforts of many billiards people over the years, just as the impression of the masses on billiards has gradually changed, the gambling fight happened just a while ago, and the news also made the social page, which is undoubtedly another serious injury. If the billiards that parents see are in such an environment, who dares to let the children still engage in the road to billiards?

　　Maybe everyone knows that gambling is not good, but why are so many people caught up in it? It’s very simple, because while gambling, dopamine will be produced in the brain, commonly known as morphine in the brain, which will make you feel extremely excited. In fact, gambling and drug abuse have the same stimulation area in the brain. Therefore, it is also the reason why the amount of gambling tends to get bigger and bigger.

　　Compulsive gambling will have some special features, such as bragging, arrogance, over-optimism, and they are usually smart. The following are 20 questions developed by Gamblers Anonymous International Service Office. If you meet more than 7 questions, you may have compulsive gambler syndrome!

　　1. Do you often get off work early because of gambling?

　　2. Does gambling make your family life unhappy?

　　3. Does gambling affect your reputation?

　　4. Do you feel regret after you gamble?

　　5. Do you gamble because you are in debt? Or do you want to solve your financial problems by gambling?

　　6. Does gambling reduce your ambition or efficiency?

　　7. After losing money, do you feel that you have to turn over the book as soon as possible?

　　8. After you win the bet, do you have an impulse to go back and win more?

　　9. Do you often gamble until you lose the last dollar?

　　10. Have you ever borrowed money from others to raise enough money to gamble?

　　11. Have you ever sold anything to raise enough money to gamble?

　　12. Are you unwilling to use "gambling money" as your daily consumption?

　　13. Does gambling make you care nothing about the welfare of your family?

　　14. Did you gamble longer than you originally scheduled?

　　15. Have you ever used gambling to escape troubles or troubles?

　　16. Have you ever used illegal actions or considered illegal actions to bet on gambling money?

　　17. Has gambling ever caused you difficulty sleeping?

　　18. Is there a lot of struggle, frustration and disappointment in your heart because you always want to gamble?

　　19. Have you ever wanted to celebrate your good luck because of hours of gambling?

　　20. Have you ever tried to commit suicide because of gambling?

　　If you have more than 7 points above, you must pay attention to moderation! ! !

　　So I really advise you to stay away from gambling and give us a clean environment for billiards! ! !

　　Cctv newsAccording to China Weather Network, in the next three days (February 25th to 27th), cold air will affect our country more frequently, but it can’t stop the general trend of warming up. The temperature fluctuates like riding a roller coaster, especially in the north, and the temperature fluctuation in some areas exceeds 10℃. In addition, since today, most of the rain and snow in the south have shrunk, and the sunshine in Jiangnan and other places has returned one after another, but there are still many rainy and snowy weather in the western region.

　　Cold air frequently disturbs temperature fluctuations and shocks, and the north-south trend is different.

　　After entering the "Eighth Nine-Year Plan", the main theme of China’s weather is warming up. However, the "warming road" is not always smooth. When winter and spring alternate, cold air activities are still frequent, and the temperature often fluctuates.

　　At present, there is a weak cold air that is affecting North China and Northeast China. There will be a new cold air coming tomorrow. The Central Meteorological Observatory predicts that from February 26th to March 1st, the temperature in Xinjiang, Northwest China, North China and Northeast China will drop by 4 ~ 8℃, and the local temperature drop will reach more than 10℃. Most of the above areas will have northerly winds of 4~6 and gusts of 7~9, and the wind in Shankou, Xinjiang will have 9~11 and gusts of 13. The cold air that will start tomorrow will have a wider impact, starting in Xinjiang on the 26th, in the northwest on the 27th and in the central and eastern regions on the 28th.

　　These two cold air streams have a more significant impact on the north. In North China, Northeast China, Huanghuai and other places, in the next few days, the temperature trend will mostly fall first, then rise and then fall. Most of the high temperatures occur from 26th to 28th, and the temperature in many places will hit a new high this year. By then, not only the highest temperatures in North China, Huanghuai and other places can reach 15 C, but also the highest temperatures in southeastern Inner Mongolia, Jilin and Liaoning will exceed 10 C.

　　In cities, such as Changchun and Shenyang, the highest temperature will reach 10℃ or above on the 27th, which is the first time this year to stand at the 10℃ mark. In cities with large temperature fluctuations, such as Lanzhou, the highest temperature can reach 16℃ on the 26th, and it will only be 7℃ on the 28th, and the cumulative cooling will be close to 10℃.

　　In the south, the influence of cold air is relatively small, and the temperature fluctuation is not as good as that in the north. In the next few days, the temperature will become a general trend. It is expected that by the end of February, the highest temperature in many places in the south of the Yangtze River will approach or reach 20℃, and the warmth will return. At the same time, the temperature difference between day and night will also widen, and the temperature difference in many places will be above 10℃. The public should still do a good job of cold protection and warmth when they leave early and return late.

　　From now on, the sunshine in Jiangnan and other places will return to the western region, and rain and snow are still frequent.

　　Yesterday, as the cold air gradually moved south, the rain and snow in the middle and lower reaches of the Yangtze River began to shrink. At the same time, there are also snowflakes falling in the Qinghai-Tibet Plateau and other places. Monitoring shows that from 08: 00 yesterday to 06: 00 today, there were small to medium snow or sleet in eastern Tibet, northwestern Sichuan, central and northern Shanxi, and heavy snow in Ganzi, Sichuan; Small to moderate rain occurred in southern Sichuan and southeastern Yunnan.

　　From today, the sunshine in Jiangnan and other places will return one after another; From 26th to 27th, there will be a wide range of sunny days in central and eastern China. However, in the western region, rain and snow still appear from time to time.

　　Today, there are small to medium snow or sleet in parts of northern Xinjiang, southern Sichuan Plateau, southeastern Gansu and southern Tibet. Among them, Tacheng, Altay and Ili Valley in northern Xinjiang have heavy snowstorms; There is light rain in parts of southeastern Tibet, southern Gansu, northeastern and southern Sichuan, and central and western Yunnan.

　　Tomorrow, there will be small to medium snow or sleet in parts of mountainous areas in northern Xinjiang and western southern Xinjiang, southeastern Gansu, eastern and southern Tibet, and southern Qinghai, among which there will be heavy snow in eastern Tibet and other places; There are small to moderate rains in parts of central and western Yunnan, northwestern Sichuan Basin and southeastern Tibet.

　　The day after tomorrow, there will be small to medium snow or sleet in parts of northeastern Inner Mongolia, northwestern Heilongjiang, southern and western mountainous areas of southern Xinjiang, eastern and northern Tibet, central and southern Qinghai, southern Gansu and western Sichuan Plateau, among which there will be heavy snow in parts of southeastern Tibet. Western and southern Sichuan Basin, western and northern Yunnan; There are small to moderate rains in parts of northern Guizhou and western Hubei.

　　The meteorological department reminded that in the next three days, there will be intermittent rain and snow in eastern Tibet, Sichuan, Yunnan, Chongqing, Guizhou and other places, occasionally sunny or cloudy, and the sunshine will not stay long. The public should pay close attention to the approaching forecast and prepare rain gear when going out; In case of slippery and icy roads, you should drive slowly and pay attention to traffic safety.

　　Xinhua News Agency, Beijing, April 20 (Reporter Ni Yuanjin) The Beijing Meteorological Bureau reported on the 20th that due to the influence of strong cold air, the Beijing area ushered in a strong wind and cooling process on the night of the 19th, accompanied by dusty weather. A blue warning signal of strong wind was issued, and the temperature dropped significantly. It is expected that this round of weather process will end on the 21st.

　　Du Jia, chief forecaster of Beijing Meteorological Observatory, said that during the day of 20th, there were 4 or 5 northerly winds and 7 or 8 gusts in Beijing. By the afternoon of 21st, there were still 3 or 4 southerly winds with 6 gusts. Affected by the upstream dust transportation and local strong winds, the dust weather began to affect Beijing on the night of the 19th, and the visibility dropped to 2-6 kilometers at the lowest.

　　The windy weather also brought about a significant drop in temperature. "The maximum temperature dropped by 10℃ to 12℃ in 48 hours. From the 20 th to the 21 ST, the highest temperature in Beijing during the day dropped to 15 C to 21 C, and the lowest temperature at night was 8 C to 12 C. " Du Jia said.

　　Sandstorm weather is divided into floating dust, sand blowing, sandstorm, strong sandstorm, extra-strong sandstorm and other different categories according to factors such as whether dust and sand on the ground are blowing and horizontal visibility. According to the Meteorological Propaganda and Science Popularization Center of China Meteorological Bureau, three conditions need to be met to form a sandstorm. First, the strong wind as the power source; Second, as the material basis, the dust source; Third, the unstable air conditions that make the dust roll higher.

　　Why do you feel windy and dusty this spring? Du Jia said that statistics show that the temperature rose rapidly in the spring of March, and the sand source areas in the north began to thaw, but there was less precipitation. At the same time, cold air activities in the north were still frequent and windy weather was frequent.

　　According to the news of China Meteorological Bureau, from 19th to 20th, due to the influence of cold air and strong wind, there were sandstorms or floating dust in southern Xinjiang basin and east, most of Inner Mongolia, Gansu, Ningxia, northwestern Shaanxi, northwestern Shanxi, northern Hebei, northern Beijing, central and western Liaoning, central and western Jilin and central and western Heilongjiang. Among them, there were sandstorms in parts of southern Xinjiang basin, western Inner Mongolia and Hexi Gansu, and there were strong sandstorms locally.

　　The meteorological department reminds that when windy and dusty weather occurs, you should stay away from tall buildings, billboards and temporary structures, and beware of falling objects. The elderly, children and people with respiratory allergic diseases should try their best to go out, and outdoor activities need to wear masks for protection.
