How to deal with the blank wall to achieve the ideal effect? What are the precautions for this treatment?

The treatment of blank wall is an important link in house decoration. Proper treatment can lay a good foundation for the subsequent decoration work, and also enable the wall to achieve the ideal decorative effect. The following is a detailed introduction to the treatment methods and related matters needing attention of the blank wall for you.

The first is grass-roots treatment. There are usually impurities such as dust, oil pollution and loose objects on the surface of the blank wall, which need to be cleaned comprehensively first. You can use brooms, vacuum cleaners and other tools to remove dust. For the parts with serious oil pollution, you can use cleaning agents to wipe them. If there are cracks, holes and other defects in the wall surface, it needs to be filled with gypsum or special repair materials. Small cracks can be directly repaired with putty, and larger cracks need to be embedded with bandages or mesh cloth before filling them to prevent cracks from cracking again.

The next step is wall leveling. Uneven wall will affect the subsequent decoration effect, so leveling is needed. Commonly used leveling materials are cement mortar and putty powder. If the deviation of wall flatness is large, coarse leveling can be carried out with cement mortar first, and fine leveling can be carried out with putty powder after drying. When daubing putty, it is generally necessary to daub it for 2-3 times, and the interval between each time should be determined according to the weather and material description, usually 1-2 days. The thickness of each application should not be too thick to avoid cracking.

Then it is sanded. After the putty is dried, it is necessary to polish the wall surface with sandpaper to make the wall surface smoother and flatter. The mesh number of sandpaper should be selected according to the flatness and grinding stage of the wall. Generally, rough sandpaper is used for preliminary grinding first, and then fine sandpaper is used for fine grinding. Pay even attention when polishing to avoid polishing marks.

Finally, the wall decoration. After the previous treatment, the wall can be decorated, such as painting latex paint and pasting wallpaper. When painting latex paint, we should pay attention to selecting products with good quality and high environmental protection performance, and make deployment and construction according to the requirements of the manual. When pasting wallpaper, pay attention to the splicing and alignment of wallpaper to avoid problems such as empty drum and edge warping.

In the process of dealing with the blank wall, there are also some matters needing attention. When treating at the grass-roots level, it is necessary to ensure that the wall is completely dry before the next step of construction, otherwise it will affect the adhesion and drying speed of subsequent materials, and even lead to problems such as moldy and falling off the wall. In the process of wall leveling, it is necessary to control the proportion and coating thickness of cement mortar and putty powder to avoid cracking and hollowing. When sanding, you should pay attention to protective measures, such as wearing masks and gloves, so as to avoid inhaling dust and causing harm to your body. In the stage of wall decoration, we should pay attention to the temperature and humidity of the construction environment, and avoid the construction in the environment of high temperature, high humidity or low temperature, so as not to affect the decoration effect.

The following is a simple comparison table for you to understand the main points of different processing stages:

Processing stage processing method matters need attention Basic treatment Clean the wall and fill the cracks and holes. Make sure the wall is dry. qiangmianzhaopin Coarse leveling of cement mortar and fine leveling of putty powder Control material proportion and coating thickness sand papering Use coarse sandpaper first and then fine sandpaper. Take protective measures. Wall decoration Paint latex paint and paste wallpaper. Pay attention to the construction environment temperature and humidity.

Through the above methods and precautions, I believe you can handle the blank wall to achieve the ideal effect and add a beauty and comfort to your home environment.

China gave US$ 200 billion in concessions? Don’t believe it, it’s a rumor.

  Diplomacy is no small matter. Some seemingly casual details often reveal meaningful signals.

  Just now, in the Oval Office, US President Trump met with Liu He, Vice Premier of the People’s Republic of China, the special envoy of the Supreme Leader. The meeting lasted 40 minutes. According to the subsequent release of Xinhua News Agency, Trump also emphasized to Liu He:I highly cherish the good working relationship and personal friendship with the Chairman of the Supreme Leader.

  Trump, the chief correspondent of Twitter in the White House, also quickly posted relevant information on Twitter, saying that he had talked with Liu He about trade issues. In the photo, Trump with a red tie stood on the right and Liu He with a blue tie stood on the left. They shook hands and smiled.

  Sino-US trade negotiations are still going on, but during the talks, Trump suddenly met Liu He at the White House, and the information conveyed should be quite rich, at least these three clear signals:

  1. There have been subtle changes in the attitude of the United States.

  The last time Liu He visited Washington, not long ago, US Treasury Secretary Mnuchin led a delegation to Beijing for consultations, but the top leaders of the two countries did not come forward to meet. But this time, Trump not only met with Liu He, but also smiled brilliantly.In addition to Mnuchin and other US ministers, accompanied by US Vice President Burns. The President and Vice President of the United States met with Liu He, a vice-national.It can also be seen that the US attaches great importance to the China delegation.

  In addition, in the Xinhua News Agency report, the first thing Trump said to Liu He was,"It is very important for the United States and China to maintain good cooperative relations in the economic and trade field." Please note that this is "very important".Since it is very important, the United States should also be soberly aware that once it derails, it will shake the earth.

  Second, China and the United States have differences, but both want to solve them properly.

  According to Xinhua News Agency, Trump said to Liu He:"I hope that the economic teams of the two countries will work together to actively solve the problems existing in the economic and trade relations between the two sides."Liu Heze said:"China is willing to work with the United States to properly handle and solve economic and trade issues of mutual concern on the basis of equality and mutual benefit, and ensure that economic and trade cooperation will continue to be the ballast stone and propeller of Sino-US relations."

  There are indeed big differences between the two sides. What should we do? Please note that the Chinese word is "properly handled" and Trump’s word is "actively resolved". There are subtle differences in words, but their attitudes are basically the same. In other words, both sides believe that these differences should not be allowed to affect the relations between the two countries, which creates better conditions for the final success of the negotiations. Of course, China also has principles: on the basis of equality and mutual benefit.

  Third, there is huge space for future cooperation between China and the United States.

  During the meeting, Trump also said this to Liu He:The United States and China should focus on strengthening trade and investment cooperation in the fields of energy and manufacturing, expanding agricultural products trade and market access, and strengthening cooperation in intellectual property protection to bring more practical benefits to the two peoples.

  This should be the key cooperation area listed by the United States.These are all businesses, and China really may not suffer.It must be noted that in these areas, the United States has great advantages, and China’s appropriate increase in some imports is conducive to meeting people’s needs for a better life and is more conducive to the formation of a domestic competitive market. For example, energy is the blood of the economy, and China needs to import a lot of energy to develop; China needs blue sky, and natural gas is in short supply. In this regard, the United States can make more contributions. Of course, China’s energy exploitation technology should also catch up quickly.

  In the previous article, bullpiano said,The trade war between China and the United States seems to be on the verge of exploding, but from the perspective of the ultimate win-win situation of harmony and wealth, it is just a fierce bargaining before larger-scale cooperation.

  For the delegation of China, this is really a heavy responsibility. We must defend China’s legitimate rights and core interests, and we must defend the multilateral free trade system and global free trade.

  Because in the process of consultation, there is no lack of wild speculations. Some western media also broadcast the so-called news that China made substantial concessions and accepted the US deficit reduction of $200 billion.

  However, people familiar with the matter made it clear that this is false and purely misunderstood.

  According to the interpretation of relevant people:

  1. It is absolutely impossible for the Chinese team to negotiate under the conditions set by the US. This point has long been made public in the last round of Beijing consultations.

  2. Some of China’s concerns, such as the ZTE incident, have been hinted by the relevant US parties in Twitter a few days ago; In addition, both sides have made progress in expanding the export of chips and high-tech products to China in the United States and relaxing energy exports to China. The final result of this transaction is worth looking forward to. Some people worry that China will make unilateral concessions, which is unnecessary.

  3. The final result of the negotiations will come out after a while, and the so-called rumors of China’s concessions will be broken by then!

  However, this is still a bitter battle.

  According to informed sources,Just a few hours before Trump met with Liu He, the two sides still refused to give in to each other on the focus issue, and the negotiations were once deadlocked.Trump’s sudden meeting and the smiling handshake between the two sides undoubtedly put an end to the hard negotiation of this day.

  Negotiations will continue and the game is still going on. Strive for the best results and prepare for the worst.Tomorrow is a crucial day!(Author Niu Qinqin)

Opening season | Message from President of Peking University: Listen to the voice of learning and "learn to be an adult"

"Don’t imprison curiosity because of grades. Every course and every topic is an opportunity to explore the mysteries of nature and human beings." Lin Jianhua, president of Peking University, delivered a speech on the topic of "Listening to the voice of learning" at the ceremony on September 8th.

On the same day, more than 3,000 freshmen from 2017 Peking University gathered in Peking University Qiu Deba Gymnasium for the opening ceremony. Zhao Lanxin, who won the first place in the Chinese Women’s Mathematical Olympiad, spoke as a freshman representative. The "mathematical genius" said that writing is also her inner passion. She used "Why don’t teenagers dream of catching stars?"? Dare to shoot the jade scale with a mulberry bow. Don’t be too smart today, and invite him to see the sea level tomorrow. " Poems to express their outlook on college life.

Before the ceremony, Professor Hao Ping, secretary of the Party Committee of Peking University, read out the decision of commending doctoral students, and more than 500 doctoral students won this honor. In order to encourage doctoral students to engage in high-level scientific research and improve the quality of doctoral students’ training, since 2009, Peking University has established a doctoral student principal scholarship, which is the highest honor, the largest amount and the most influential postgraduate scholarship established in Peking University. Professor Hao Ping called on the students to follow the example of the commended students, study hard and concentrate on scientific research.

Principal Lin Jianhua: Learn to be an adult.

"Don’t imprison curiosity because of grades. Every course and every topic is an opportunity to explore the mysteries of nature and human beings." President Lin Jianhua said to the students, "I want to remind everyone not to be too utilitarian and short-sighted, and not to go with the flow;" Follow your heart and find your own interests. In fact, professionalism is hidden behind every major. "

He said that in order to encourage students to develop freely, Peking University supports the free transfer of majors within the department and the free selection of courses in the whole school. The interdisciplinary training plan also gives students a very broad choice, and the way of thinking and values are more important than knowledge. "Knowledge can be out of date, but the way of thinking, social responsibility and spirit of exploration that you feel will flow in your heart like blood and accompany you all your life."

Lin Jianhua mentioned that in the face of the rapid development of science and technology in today’s society, some people will wonder whether science and technology will shake the cornerstone of human society and human civilization. He quoted Apple CEO Cook’s speech at the MIT graduation ceremony: "I am not worried that artificial intelligence can give computers the ability to think like humans. I am more worried that humans think like computers."

"Our education is not about turning people into machines, but about learning to be human." Lin Jianhua said, "Learning is not to passively accept knowledge, but to form one’s own experiences and opinions through comparison, speculation, debate and practice, so as to truly grasp the law, seek the true meaning and establish socialist core values."

He said: "Learning to be an adult is also a process of discovering your own ignorance. Being brave in discovering and admitting your own ignorance is the real performance of self-confidence. Always keep an open mind, be brave in questioning and learn with an open mind. I hope that students can explore, think and listen in silence and experience the joy of growth and creation. "

For a long time, rational humanism in the west has always occupied a dominant position. Facing the challenges of globalization and resources and environment, Lin Jianhua believes that the concept of "all things are one, and heaven and man are one" in China’s traditional culture, as well as the benevolent way expressed by "don’t do to others what you don’t want them to do to you" and "stand up for others if you want to stand up, and achieve what you want", will provide a more solid ethical foundation for the development and progress of mankind.

President Lin Jianhua spoke at the ceremony.

Zhao Lanxin, a new student representative: Why shouldn’t teenagers dream of catching stars? Dare to shoot a jade scale with a mulberry bow

Zhao Lanxin is a 2017 undergraduate freshman from Yuanpei College of Peking University, and ranked fifth in science in Chongqing College Entrance Examination. She once won the first place in the Chinese Women’s Mathematical Olympiad and the gold medal in the all-China Mathematical Olympiad. The "mathematical genius" said in her speech that mathematics is certainly a fascinating road, which always echoes the flow of everything with concise laws, but she has a longer and tougher string in her heart, and writing is her inner passion.

"When I look around my world, I find that the world is moving rapidly. Ordinary people also have vivid joys, sorrows, loves and hates, and they are separated. Many people don’t care about these, but I have a sense of responsibility that must be recorded in my heart. What I hope is that I will write and leave a soft inscription for our times. "

"Peking University has the best mathematics major in China, and I can continue to explore the mysteries of human rationality. Peking University also has the best Chinese major in the world, so that I can use the pen and ink of interest and love to describe the world."

Different from the life ideals of most competition students, Zhao Lanxin doesn’t want to follow the ready-made model, but wants to choose a road she loves. Although she hasn’t won a gold medal in the field of literature, she has enough enthusiasm for literary creation from her heart. For her, "go out of her comfort zone and explore an unknown but desirable distance." Is the best way to realize your dreams and values. She also wishes everyone present can find and realize their dreams.

Finally, she ended her speech with a poem of her own, "Why don’t teenagers dream of reaching for stars?"? Dare to shoot the jade scale with a mulberry bow. Don’t be too smart today, and invite him to see the sea level tomorrow. "

Teacher Representative Sun Qixiang, Dean of Peking University Institute of Economics: Cherish.

"When youth dies, you lose your health without vitality, elegance and wisdom. Even if you are still young, what is the use of youth, wealth and time?" On behalf of the teacher, Sun Qixiang, Dean of Peking University Institute of Economics, warned the students to cherish their health and not to overdraw your body just because you are young. Students are required to be young people with all-round development in morality, intelligence and physique, and to balance the relationship between study and exercise.

When talking about the dream and desire of youth, Sun Qixiang said, "Please cherish your inner desire, and don’t ignore and suppress it, or even snuff it out, and do what you like, instead of following others’ advice and being impetuous. Don’t compare with others, it’s enough to be the best yourself. "

Combined with his study experience, Sun Qixiang said, "This era has given everyone a chance. However, any beautiful era did not come out of thin air, but was created by thousands of builders through hard work, and the best treasure is to make due contributions to this era. "

In addition, Sun Qixiang told the students to cherish the present, others, teachers and students, friends and parents’ efforts and hard work.

President Lin Jianhua.Full text of speech

Good morning, dear classmates!

In the most beautiful season in Beijing, Peking University welcomed the new students of 2017, and the youthful vitality filled the beautiful campus with joy. We often compare a university to a big family, in which students, teachers, employees and alumni are all important members. Whether you are new to Peking University or continuing your studies here, we are soul mates, simple and pure, and strive to move forward. Welcome! Welcome to join the big family of Peking University!

Looking at everyone’s youthful smiles, I think of the first time I came to Peking University. It has been forty years since. The past 40 years, like a realistic version of the travel drama, have changed so much that people can’t imagine.

Zhongguancun Street was called Baiyi Road at that time, which was a rural road, with thick and towering Populus tomentosa and rice fields on both sides full of rural interests. At that time, it was still a big thing to go to town. There was only one bus No.332, or a bicycle that was still a luxury was about to be borrowed.

Forty years have passed, and everything is changing, but one thing remains unchanged, that is, Peking University people’s feelings for home and country, their fearless spirit of being the first in the world and their unremitting academic pursuit.

What will happen in the future? What kind of world will you face? This may be a doubt in the hearts of many young people. The rapid development of science and technology has changed people’s way of life and work, and the rapid rise of China has changed the traditional world political structure. These things sound great and far away, but they have already happened to us.

Making students become people who can lead the future is the talent training goal of the school, and it is also a challenge to educational concepts and traditions. The school is carrying out undergraduate education reform and postgraduate training mechanism reform, with the aim of providing you with a better learning and growth experience.

Everyone will soon enter the first grade course. Some students will be very concerned about grades, but don’t imprison their curiosity. In fact, every course and topic will give you an opportunity to explore the mysteries of nature and human beings.

University is a journey of exploration, discovery and creation by teachers and students. Follow your curiosity and explore the way of thinking behind knowledge with innovative and critical eyes, and you will surely gain more.

People often say that "interest is the best teacher", and the free transfer of majors in the department, free course selection in the whole school and interdisciplinary training plans will provide you with broad choices.

I want to remind everyone not to be too utilitarian and short-sighted, and not to go with the flow; Follow your heart and find your own interests. In fact, there is a professional spirit behind every major. Knowledge can be out of date, but the way of thinking, social responsibility and spirit of exploration you feel will flow in your heart like blood and accompany you all your life.

As we all know, AlphaGO defeated the top human Go player and made a major breakthrough in gene editing technology. This makes some people worry that science and technology will shake the cornerstone of human society and human civilization. That’s not how I see it.

Apple CEO Cook put it very well. He said, "I’m not worried that artificial intelligence gives computers the ability to think like human beings. I’m more worried that human beings think like computers-abandon compassion and values and be reckless."

Our education is not to turn people into tools and machines, but to "learn to be adults".

There will be an important international conference in Peking University next year-the 24th World Philosophy Conference, with nearly 5,000 philosophers from all over the world attending, which will be a grand gathering where eastern and western civilizations collide and blend. The theme of the conference is "Learning to be human".

For a long time, rational humanism in the west has always occupied a dominant position. Facing the challenges of globalization and resources and environment, I believe that the concept of "all things are one, and heaven and man are one" in China’s traditional culture, as well as the benevolent way expressed by "don’t do to others what you don’t want them to do to you" and "stand up for others if you want to stand up, and achieve what you want", will provide a more solid ethical foundation for the development and progress of mankind.

"Learning to be an adult" is a proposition that accompanies us all our lives. Philosophy considers "learning to be an adult" from the theoretical level, while education is the practice of "learning to be an adult".

Learning is by no means a passive acceptance of knowledge, and you can’t swallow dates and follow others’ advice. Instead, you should form your own insights through comparison, speculation, debate and practice, so as to truly grasp the law, seek the true meaning and establish the core values of socialism.

General Secretary of the Supreme Leader said: "Active thinking is an important feature of colleges and universities, where various ideas and viewpoints meet and various values collide. Taishan does not let the soil, so it can become a big one; Rivers and seas do not choose small streams, so they can be deep. We must uphold the attitude of respecting differences and accommodating diversity, lead by pluralism and neutrality, seek consensus in diversity, set the direction in change, and let all the trickle of beneficial ideology and culture merge into the vast sea of mainstream ideology. "

"Learning to be an adult" is also a process of discovering your ignorance. In ancient Greece, there was a philosopher, Zhi Nuo, the father of paradox. Students once asked him, "Teacher, you are knowledgeable, why do you always question your own conclusions?" Zhi Nuo drew two circles and said, "The big circle is me and the small circle is you. If the area of the circle is the knowledge we have, the outside of the circle is unknown, and the circumference is the unknown we can contact. The more visible knowledge, the more unknown we contact. "

The courage to discover and admit your ignorance is a sign of true confidence. You are all excellent. I hope that you will not be afraid of problems and difficulties, be dogmatic and inflexible, and always keep an open mind, be brave in questioning and learn with an open mind.

German philosopher Garf once said: "The voice of conscience is silent, and it is hard to be heard in the hubbub." The same is true of learning, which requires us to forget the worldly customs and explore, think and listen in silence.

I wish you all can calm down, listen to the voice of learning and experience the joy of growth and creation during your time at Peking University.

Thank you!

Ministry of Commerce: Making Policy "Combination Boxing" and Striving to Stabilize the Basic Market of Foreign Investment and Foreign Trade

  CCTV News:On April 10th, the State Council Joint Prevention and Control Mechanism held a press conference. Ren Hongbin, Assistant Minister of Commerce, and Li Xinggan, Director of Foreign Trade Department, introduced relevant measures to stabilize foreign trade and answered questions from reporters.

  Ren Hongbin, Assistant Minister of Commerce, said that since the beginning of this year, affected by the COVID-19 epidemic, the development of foreign trade has faced severe challenges that have not been seen for many years. According to customs statistics, from January to February, China’s import and export, export and import decreased by 9.6%, 15.9% and 2.4% respectively in terms of RMB.

  At present, the situation of domestic epidemic prevention and control continues to improve, and foreign trade enterprises have resumed their work and production in an orderly manner. However, the global epidemic has accelerated its spread, which has brought great impact on the global economy and trade. Judging from the recent investigation of key provinces and cities, import and export chambers of commerce and key enterprises by the Ministry of Commerce, foreign trade enterprises generally face many problems such as cancellation or postponement of orders in hand, difficulty in signing new orders, and poor logistics and transportation.

  In the face of the severe foreign trade situation, the State Council timely introduced policies and measures to stabilize foreign trade. On March 10th, the the State Council executive meeting deliberated and adopted measures such as improving export tax rebate, increasing foreign trade credit and increasing export credit insurance support. On April 7th, the executive meeting of the State Council once again launched a series of policies to stabilize foreign trade, such as setting up a comprehensive cross-border e-commerce test zone, supporting the development of processing trade, holding an online Canton Fair, etc., and made a policy "combination boxing" to try to stabilize the basic foreign trade.

Be loyal to the party, be honest and not cheat.

  [Governing Concern, Studying and Implementing the Spirit of the Sixth Plenary Session of the Eighteenth Central Committee]

  Take compensation and resettlement fees by deceiving superiors and deluding subordinates; Falsely reporting exaggerated statistical data, affecting scientific decision-making; Report good news but not bad news, fool inspection and seek false political achievements … … Recently, the phenomenon of individual party member cadres practicing fraud and deceiving their superiors and deluding their subordinates in their work has been frequently exposed, which has aroused widespread concern and must be resolutely corrected.

  Seeking truth from facts is the party’s fine tradition. "Falsification, false reporting and exaggeration" is a serious political problem and a very harmful corruption. The Guidelines on Political Life within the Party under the New Situation (hereinafter referred to as the Guidelines) deliberated and adopted by the Sixth Plenary Session of the 18th CPC Central Committee clearly pointed out: "Party organizations at all levels and all party member must be loyal and honest to the Party, be honest, do honest things, and be honest" and "oppose fraud, false reporting and exaggeration, and oppose concealing the truth and not reporting bad news". Party member cadres must strictly abide by it.

  Falsification is a very harmful corruption.

  On November 18, the Intermediate People’s Court of Xining City, Qinghai Province publicly pronounced the case of Li Zhi, former deputy director of the Standing Committee of the People’s Congress of Xinjiang Uygur Autonomous Region, and sentenced the defendant Li Zhi to 12 years in prison for accepting bribes and fined him RMB 1 million. The property obtained by Li Zhi’s bribery shall be recovered and turned over to the state treasury. Previously, in the notice published on the website of the Supervision Department of the Central Commission for Discipline Inspection on July 6, 2015, it was pointed out that "Li Zhi seriously violated discipline, falsified files, and concealed his real age from the organization" and "used his position to facilitate the selection and appointment of cadres, business operations, etc. Seek benefits for others, ask for and accept huge bribes".

  "We should be soberly aware that fraud and bullying are not only a matter of style, but also very harmful corruption in many cases." Long Bing, an associate professor at the School of Marxism, Hunan University, said that in order to pursue political achievements or seek personal interests, a few party member cadres have deviated from the Party’s principle of seeking truth from facts, deceived organizations, deceived the masses and had a bad influence, and must be severely punished.

  "I thought that by taking advantage of loopholes, I could get subsidies by muddle through. Now that I think about it, this kind of behavior of deceiving the masses, deceiving party organizations and gaining personal gain is really inappropriate. " Wu Yinkun, former deputy secretary of the Party branch of Huangdi Village, Suban Town, xinluo district, Longyan City, Fujian Province, said in an investigation. Wu Yinkun was kept in the party for one year because of illegal declaration of subsidy funds for renovation of dangerous houses.

  In recent years, some localities and departments have made false reports on statistical data, used false data to compete for fame and gain profits, and have been investigated and punished. The National Audit Office once issued a notice saying that Yongfu County in Guilin, Guangxi falsely reported the number of starts and the number of completions in the renovation of dilapidated houses in rural areas. 1509 households actually started construction, and 1920 households were reported to have started construction; 834 households were actually completed and 1,500 households were reported to have been completed. At present, Yongfu County has investigated the responsibility of the relevant staff, and given disciplinary and political sanctions to the leaders in charge of the County Housing and Construction Bureau and the relevant township leaders.

  According to reports, at the signing site of an investment promotion meeting in a province in northwest China, several projects that had already signed contracts were "performed" at the signing site again. "In recent years, it has become an open secret for some places to falsely report and exaggerate the data of investment promotion projects. This reflects the distorted view of political achievements of some leading cadres. " Peng Runjin, deputy director of the Political Science Teaching and Research Department of the Party School of Jiangxi Provincial Party Committee, said.

  "It’s better to say what you can do than to show what you can say. At present, in some localities and units, the problem of reporting good news without reporting bad news is also quite prominent. Tell the superior unit about the achievements and good aspects, and make great efforts to render them, but ignore the problems and difficulties. Failure to investigate, punish, or even condone those who resort to fraud has further contributed to this false and deceptive wind. " Long Bing said.

  In the final analysis, it is impure party spirit and incorrect style of work.

  "Power is a public instrument for serving the people. No matter what position you are in, you should perform your duties with awe and sincerity. Falsification and bullying are, in the final analysis, impure party spirit and incorrect style of work, and they are disloyal and dishonest to the party. " Chen Liaomin, vice president of the Xihu District People’s Court in Hangzhou, Zhejiang, said.

  Analyzing the causes of fraud and other phenomena, experts generally believe that, first, individual party member cadres have weakened their party spirit and indifferent sense of purpose, engaged in formalism in their work, made superficial articles, and even abused power for personal gain; Second, some places or units have the wrong orientation of selecting and employing people and unreasonable assessment system, which leads to individual party member cadres being good at "exaggerating" their achievements, being good at "covering up" their mistakes, or deceiving some unrealistic assessment indicators by fraud; Third, the supervision of power is weak and the punishment for violations of laws and regulations is not enough, which has not formed an effective deterrent.

  Zheng Dai, a cadre of the Research Office of the Organization Department of Yiyang Municipal Committee of Hunan Province, believes that some leading cadres have bureaucratic style and do not go deep into the grassroots to conduct research. Even if they go on, they just listen to reports and look at materials. Even the research routes and interviewees have been arranged at different levels, making it difficult to understand the real situation. This gives fraudsters an opportunity.

  "Whether you can seek truth from facts in your work tests whether the party spirit of party member cadres is firm." Sun Chengyao, a researcher in the Department of Teaching and Research of Party History and Party Construction at the Party School of Zhejiang Provincial Party Committee, said that party member cadres’ falsification, false reporting and exaggeration and one-sided pursuit of abnormal outlook on political achievements are putting the cart before the horse in serving the people and their personal reputation. They should start from their ideological roots, supplement their spiritual calcium and establish a realistic outlook on political achievements.

  "Since the founding of New China, especially in the past 40 years of reform and opening-up, China has made remarkable development achievements, thanks to the loyalty and honesty of thousands of party member cadres in Qian Qian, who insist on being honest, telling the truth and doing honest things. Falsification and bullying have seriously affected the party’s image and the party’s career development. " Long Bing said.

  Be honest, tell the truth, do honest things.

  "Falsification not only affects the scientific decision-making of the party and the government, but also harms the interests of the people. It will also dampen the enthusiasm of party member cadres who are practical and destroy the political ecology within the party and must be severely corrected." Sun Chengyu said.

  A correct view of power is like an inner law, which leads party member cadres to seek truth from facts and go straight on the right path. He Husheng, a professor at the School of Marxism of Renmin University of China, said that party member cadres should constantly improve their party spirit, strengthen their political determination, be loyal to the Party, consciously fight against unhealthy trends such as formalism and bureaucracy, and maintain the political nature of communist party people.

  "To make being an honest man become party member’s pursuit, we should always tighten the string of loyalty to the party, take the initiative in the face of urgent and dangerous tasks, and keep the bottom line in trivial matters." In Zheng Dynasty’s view, it is not enough for party member to be honest, only by individual consciousness. It is also necessary to organize people who dare to show their swords to dishonest people and things, and resolutely curb the abnormal phenomenon of "honesty suffers".

  He Husheng said that it is necessary to adhere to the correct orientation of selecting and employing people and select cadres who do practical things and do practical things. At the same time, the party’s political discipline should be strictly observed, and an institutional arrangement should be formed in which the power must be held accountable, the use of power must be held accountable, and the abuse of power must be held accountable. For some cadres who do not do practical things, they should strengthen supervision and accountability, increase punishment, continuously reduce the occurrence of fraud, and urge cadres to consciously tell the truth, do honest things, and be honest.

  "Make full use of internet plus’s public supervision, broaden the channels for people’s supervision, let party cadres be tested in a wider social space, and let those cadres who practice fraud and make false reports have nowhere to hide." Peng Runjin said.

  The General Secretary of the Supreme Leader pointed out: "To be honest is to be loyal and honest to the party, the people and comrades, to be honest, to be honest, to be honest, to be honest, to be fair and upright." The words are still ringing in our ears, and party member cadres must always keep them in mind.

Speaking of Helicobacter pylori (Hp), I think everyone is familiar with it. Hp is a gram-negative spiral bacteria, which mainly spreads from person to person through oral route [1]. The infection rate of Hp in Chinese is very high, exceeding 50%, and the current research proves that Hp has an ambiguous relationship with gastric cancer, and the World Health Organization (WHO) has identified it as a grade I carcinogen of gastric cancer.

Traditional treatment has always relied mainly on acid inhibitors combined with antibiotics to eliminate Hp to treat related diseases caused by it, but the abuse of antibiotics has led to the rising drug resistance rate of Hp. So, can we eradicate Hp? I’ve heard of many kinds of vaccines. Is there an Hp vaccine?

At the just-concluded 20th National Academic Conference on Digestive Diseases of Chinese Medical Association, Professor Zou Quanming from the Biopharmaceutical Teaching and Research Section of the Department of Pharmacy of Army Military Medical University gave a wonderful report on the theme "How far is Hp vaccine from us?".

Do we need Hp vaccine?

First of all, Professor Zou Quanming raised a question: Do we need Hp vaccine?

▎Hp is closely related to gastric cancer and has serious harm.

At present, there are three different views on Hp in the medical field:

1. The pathogenicity of Hp is serious, and vaccine is needed for radical cure;

2. Hp is still helpful to the human body, even probiotics;

3. Hp and human beings have coexisted for a long time, and their existence is reasonable.

These different viewpoints have seriously affected the research and appearance of Hp vaccine.

According to the data released by the National Cancer Center in 2017, there are about 680,000 new cases of gastric cancer in China each year, accounting for nearly one-third of all cancers in China, accounting for about 50% of the total incidence in the world, and the mortality rate also accounts for about 50% of the world total. Hp infection can almost always cause active inflammation of gastric mucosa. On the basis of chronic inflammation, some patients can also develop a series of diseases such as peptic ulcer and gastric cancer (1%).

Hp infection has brought great disease burden and economic loss to people, but at present, people pay insufficient attention to Hp. Professor Zou Quanming emphasized that Hp is very harmful and we need Hp vaccine.

▎ At present, antibiotics are used to treat Hp, but the symptoms are not cured.

Traditional treatment has always relied mainly on acid inhibitors combined with antibiotics to eliminate Hp to treat related diseases, but antibiotics can only eliminate the existence of individual Hp or suppress its proliferation, and can not achieve the goal of eradicating Hp for the whole society. And the drug resistance caused by frequent use of antibiotics, such as clarithromycin and metronidazole, has become a serious problem in some countries. In addition, the use of antibacterial therapy to eradicate Hp is not sustainable. In some countries, the annual recurrence rate of Hp is as high as 15%-30%.

Professor Zou Quanming said that China, Japan, South Korea and other countries in the Far East, including many countries in Eastern Europe, have a high incidence of gastric cancer. Under the condition of extensive vaccination, even if the hidden Hp infection of patients is not detected, the incidence of gastric cancer can be reduced. In developed countries, it is calculated that a 10-year vaccination program can greatly reduce the prevalence of ulcer and gastric cancer caused by Hp, and also reduce the incidence of related diseases and economic losses.

Basic questions to be answered in Hp vaccine research

However, the research of Hp vaccine is not smooth sailing. Professor Zou Quanming pointed out that it is very difficult to study Hp vaccine and the following problems need to be solved:

1. Why is the immune response caused by natural infection of the host not protective?

2. What are the mechanisms and differences between immune protective response and pathological injury?

3. Screening and transformation of vaccine effective antigen?

In addition, the immune mechanism of Hp infection is very complicated.

Figure 1: Infection immune mechanism of 1:Hp

Research progress of preventive Hp vaccine

Next, Professor Zou Quanming introduced the research progress of Hp vaccine at home and abroad:

Figure 2: Research progress of Hp vaccine at home and abroad.

Professor Zou Quanming and his research team established the strategy of "intramolecular adjuvant mucosal vaccine of Hp", which has been verified by practice. This technique can produce sIgA antibody in gastrointestinal mucus (which is completely different from serum IgG antibody), thus blocking Hp infection.

Fig. 3: Mechanism of action of intramolecular adjuvant mucosal vaccine of 3:Hp.

Animal experiments show that the protective rate of the oral recombinant Hp vaccine in mice, rats and rhesus monkeys is more than 80%.

In addition, Professor Zou Quanming and his research team established an efficient system for screening components of Hp vaccine for the first time, and successfully constructed an engineering strain of Hp vaccine that can be used for production. More than 300 strains of Hp and more than 1,500 candidate protein components were collected from patients in 20 provinces and cities in China, and finally the Hp vaccine components were selected, and an efficient and stable vaccine purification process was established. The purity of the produced vaccine protein was over 80%, and the output was 400,000 mg/time (reaching the production scale).

In 2015, the clinical research results of "Oral Helicobacter pylori vaccine phase III" conducted by Professor Zou Quanming and his research team were published online in the top medical journal The Lancet.

Figure 4: The research results are published online in The Lancet.

In this study, more than 30 technical specifications, standards and experimental detection technologies necessary for human clinical trials of Hp vaccine I, II and III were established. And through the invention and creation of the above key technologies, more than 4,000 volunteers aged 6-15 have been developed and completed in phase I, II and III human clinical trials.

Figure 5: Distribution and shedding of subjects

Figure 6: Analysis results of infection prevention effect

The results showed that there were 64 cases of Hp infection during the follow-up period, that is, 14 cases were infected in the vaccine group (2025 people) and 51 cases were infected in the control group (2058 people). The total protection rate of oral recombinant Hp vaccine against infection was 71.8%.

In terms of safety, 157 (7%) people in the experimental group and 161 (7%) people in the control group had one or more adverse reactions during the study. Among them, 5 (< 1%) people in the experimental group and 7 (< 1%) people in the control group had serious adverse reactions, but they all thought it had nothing to do with vaccination [2].

This shows that oral recombinant Hp vaccine is "effective, safe and immunogenic" among children who are not infected with Hp, which can significantly reduce the incidence of Hp infection.

Professor Zou Quanming said that he also took the Hp vaccine at that time. Up to now, he has been tested for Hp once a year, and the results have been negative.

This study is the first phase III trial of Hp vaccine in the world. Professor Philip Sutton of Melbourne University in Australia made a special comment on this study: "The successful development of this vaccine has taken an important step towards preventing gastric cancer caused by Hp. This will rekindle human passion for this important topic, further encourage more investment, and promote continuous progress in this field through in-depth clinical trials. "

The Hp vaccine is still in the approval stage and has not been approved for marketing. At the scene, Professor Zou Quanming also expressed his expectation and called on academic organizations and Hp study groups to jointly promote the listing of Hp vaccine.

Double innovation of science and technology broadens the road of high-quality employment

Xinhua News Agency, Zhengzhou, October 21st Title: Innovation of Science and Technology Broadens the Road to High-quality Employment

Xinhua News Agency reporter Han Chaoyang

In 2020, there will be 278,000 high-tech enterprises in China, which will provide 38.588 million jobs. During the National Mass Entrepreneurship Innovation Week in 2021, innovation and entrepreneurship in the field of science and technology promoted high-quality employment, which became the consensus of experts attending the main venue in Zhengzhou.

Zhang Mu, a second-level researcher at the Torch Center of the Ministry of Science and Technology, said at the High-quality Development Forum of Science and Technology Innovation in the New Era held recently that since 2014, all kinds of science and technology entrepreneurial service institutions have sprung up all over the country, achieving a leap-forward growth, and it will grow to 14,500 in 2020, serving nearly 680,000 entrepreneurial teams and enterprises, and its support for science and technology innovation is increasing day by day.

At the same time, the integration mechanism of scientific and technological achievements transformation and innovation and entrepreneurship has gradually taken shape. By the end of 2020, more than 2,100 new R&D institutions with R&D, transformation and incubation functions have been established nationwide to accelerate the commercialization of scientific research results and support industrial technological innovation.

At present, high-tech enterprises account for 25.2% of the total number of industrial enterprises in China, achieving 33.4% of operating income and 40.3% of total profits. In 2020, domestic invention patents authorized by high-tech enterprises accounted for 49.2% of the country.

Experts attending the meeting generally believe that after opening up the chain of application research and development, transfer and transformation, business incubation and industrialization, the main position of technological innovation of enterprises has been greatly improved, and the role of technological innovation in driving high-quality employment has become increasingly prominent.

"Technological innovation drives the migration of occupations, industries and even social structures." Mao Daqing, founder and chairman of Youke Workshop, said at the "Science and Technology Innovation China" new era entrepreneur talk activity that the technological revolution promotes the transformation and upgrading of traditional industries, and technological innovation is the core of the industry transformation and upgrading. In this process, some low-creative jobs will be replaced, a large number of new jobs will be created, and at the same time, knowledge and technology upgrading of some jobs will be promoted.

It is reported that high-tech enterprises will provide 38.588 million jobs in 2020, among which 516,000 new college graduates will start businesses.

Participants pointed out that in the process of technological innovation, financing difficulties are still the shortcomings of technological innovation. "Scientific and technological innovation needs ecological environment, innovative talents are seeds, venture capital is sunshine, and market environment is soil." Yuan Hongwei, the founding partner and chairman of Zhuo Yuan Capital, believes that the long-term continuous positive movement of the three elements can create a good innovation ecology, but the low proportion of long-term capital is the shortcoming of the current innovation ecology.

China Science and Technology Innovation Work Development Report 2020 issued by Torch Center of Ministry of Science and Technology also points out that the financing difficulties of start-ups are more serious. After the epidemic, venture capital funds, bank credit and other financing channels pay less attention to start-ups and lack capital support channels.

Yuan Hongwei said that he hopes that more social resources can be allocated to this field and contribute to creating a good innovation and entrepreneurship ecology.

Can the box office miracle of A Story More Sad than Sadness be copied?


Special feature of 1905 film network Director and screenwriter Anxian Lü never thought that the movie (hereinafter referred to as "Than Sadness") could achieve such high results at the box office. In the eyes of the outside world, while their creation caused a sensation, it would be followed by pressure.


Admittedly, the two did worry in a short time. How to make a difference between the next work and Than Sadness? Will you have greater expectations for yourself?



After calming down, they found that the answer turned out to be no, so it is better to devote themselves more to their creation.


Perhaps from the outside world, Friends of the Week and Than Sadness have many similar keywords: remake, illness, emotion &hellip; &hellip;But in fact, Lin Xiaoqian and Anxian Lü took over Friends of the Week much earlier than the latter.



Although the outside world always thinks that Lin Xiaoqian has made many works with youthful elements, in reality, he has never really made a youth film in school uniform. So, he hit it off with the screenwriter Anxian Lü, so it’s better to say goodbye to their youth with Friends of the Week.



Just like the movie slogan, "Let’s meet! Summer and friendship can’t live up to it. " Then, what kind of work will "Friends of the Week" come slowly after "Than Sadness"?

A different adaptation


The original "A Week’s Friends" is a well-known Japanese girl, who has produced an animated series and a live-action movie, which is quite difficult for the China version.


Whether it is localization or difference, these old-fashioned topics have long appeared in the plans of directors and screenwriters. While the audience was still wondering whether the director would remake the story frame by frame, the screenwriter had already made a subversive adaptation of the story.



Just like the title of the film, time memory is the starting point of the work itself, and emotion is just a branch line that spreads along it.


So does human memory lie? There may be no solution. After all, the Mandela effect tells us that people sometimes have some false memories. Director Lin Xiaoqian grasped this point, "I want to differentiate between memory and truth and falsehood."


Screenwriter Anxian Lü also thinks that many plots in the original work are difficult to happen in China, and even some emotional expressions are not in line with everyone’s cognition, so it is better to make some more daring and exciting adaptations on the basis of following the original story.



As a result, the first half of the story of Friends for a Week retains the logic of the original story, but it is subverted later and expanded more richly.


To this end, the team also translated the script into Japanese and handed it to the original author. "I didn’t expect you to have such an idea." The new idea surprised Ye Yue Matcha very much.



Since youth can’t stay, it’s better to make youth more dreamy. In Anxian Lü’s view, everyone in youth has an unconstrained style.


Lin Xiaoqian, the director, also didn’t want to make the story too realistic, with some fantasy, like the cup of Corbis in the summer afternoon, with refreshing bubbles.



So, he planted a small egg in the movie.


"In the scene where Lin Xiangzhi went to buy a goldfish, she bought a goldfish on an overpass. The street lamp of that overpass caught a glimpse, but what did it look like?" He made a wonderful change to the street lamp. Is it a lamp or something else? Whether Lin Xiangzhi is in reality or divorced from reality, "whether it is true or not, perhaps the answer lies in the hearts of the audience."



Compared with the original infatuation with love, Friends of the Week focuses on the relationship between four good friends.As Lin Xiaoqian said, "Our youth is not so ignorant of love, but more firm and fettered by youth friendship."

The casting of youth


Emotional touch, the audience is looking at resonance and empathy, cp will add points, and the emotional ties between friends are the same.


"Friends of a Week" not only puts pen and ink on the man and woman, but also allows the audience to see the friendship between the four friends, extending from the film to the outside.



When casting, Lin Xiaoqian and Anxian Lü were very sure that the actor’s age should be similar to the role, otherwise it would be distorted.


It was first decided, and then Angel recommended Lin Yi to visit Chengdu, during which he met the director and contributed to this cooperation.In Lin Xiaoqian’s eyes, "Lin Yi is the perfect candidate".



Before the audition, Lin Xiaoqian saw a lot of Lin Yi’s past works, but most of them were cold and handsome images of Xueba, and never had a similar temperament to Xu Youshu. "I was worried at that time." Later, the director designed a method &mdash; &mdash; Find a unique flavor of essential oil for each character.


In a scene where Xu Youshu and Lin Xiangzhi quarreled, the director told Lin Yi, "From today on, this smell will disappear from your life." The words sound just fell and Lin burst into tears for an instant. Even later, when the dubbing was made up, the director took out the taste again. "He told me that the director should not come. Now when he smells this smell, he will think of the scene of quarreling with Jinmai."



So, what do they all smell like? "Today’s wheat is a Bulgarian rose, and Lin Yi is a lavender."


Not only that, but a lot of shooting work has brought the team back to youth. In order to reflect the atmosphere more truly, the director found the college entrance examination paper with the corresponding time background, taught Angel to solve problems with PK on the spot, and taught Lin Yi to draw auxiliary lines.



Filled with youthful breath, Lin Xiaoqian and Anxian Lü recalled that they were all infected.


Because the screenwriter Anxian Lü wrote a lot of underwater scenes, the director Lin Xiaoqian frequently shouted, "The water scene was filmed for 8 days, and I really’ collapsed’." It is even more difficult for the actors with poor water quality. Even so, everyone still worked hard to complete the filming.

"After we finished filming the water show, the actors all threw us into the water." Celebrations among young people are always full of vitality.

Fantasy shooting


As a matter of fact, the arrangement of water play once made the screenwriter in a dilemma.


In the middle of the story, it is necessary to arrange an accident. The original story is a car accident. "But I don’t want it to be a car accident. Everyone has already filmed it. I want to write something special." Anxian Lü knows that no matter how to deal with it, there will be a spit, so it is better to follow his own creation.



Because the film "Friends for a Week" was shot in Chengdu, there are many lakes around. In the pastoral investigation, Anxian Lü found that there were many similar accidents in Chengdu. Not only that, but this design can be more realistic and close to the struggle of the victims’ inner choices and self-suggestion.


In addition to underwater scenes, director Lin Xiaoqian also unlocked many new ways of playing in Friends for a Week.In the movie, four friends turned the abandoned astronomy classroom into a secret base.


Anxian Lü specifically noted in the script whether it can be realized by case-by-case animation. Finally, the director filmed the whole day for the scene that lasted only a few minutes, and then invited an animator to complete the imaginary effect.



Compared with the creation of many real movies, this form of frame-by-frame animation will often appear in music movies (MV), and the implantation of novel forms will naturally face many doubts.


Whether it’s MV shooting or innovation, Lin Xiaoqian is not worried about the audience’s opinion. After all, the film has developed for more than a hundred years, and the most attractive place is to create it with images. Even in the later period of Friends of the Week, the director did a lot of tricks in mixing. "We will mix the bass with the stress and the drums will be very clear."


The partner is not stingy with his praise for the director. "This is already the director’s style, and" Friends of the Week "is not a realistic theme. We hope to have a space for imagination and play."



If so, "Friends of the Week" may be half finished in production.The remaining half, everything is handed over to the audience. For the director and screenwriter, the next project has already started.


It’s just that after two consecutive remakes, people can’t help wondering whether they will return to the original script.


Anxian Lü told us that his next work is an original project. Lin Xiaoqian sold a pass. "I really want to shoot a story about the combination of soft science fiction and love."As for the story, "I don’t want to give myself that burden."


Beijing patrolman distributes domestic revolvers to avoid fatal damage with one shot.

  Beijing News: Domestic revolvers weighing 0.70 kg and equipped with rubber warheads will be distributed to frontline patrol police in the near future to replace the existing standard pistols. At present, the gun has been distributed to all district and county public security bureaus in Beijing and stored in gun depots, and the police have also started shooting training.


  It is understood that the revolver magazine can hold six bullets, with small recoil and high shooting accuracy. The effective and accurate killing distance is about 50 meters, and the current standard pistol has an effective killing distance of 150 meters.


  The main reason for changing guns this time is to avoid unnecessary fatal shots. Judging from the effect, the revolver has a strong deterrent, while the gun is slightly less powerful, so there will be no situation that "the bullet penetrates the suspect and hurts the nearby people". After the suspect was shot, he basically lost his combat effectiveness and would not be killed on the spot. Revolvers can be equipped with steel warheads and rubber warheads, and frontline patrol police will mainly use rubber warheads in their daily patrols. As long as you avoid the weak parts such as the eyes and ears of the target person, the rubber warhead will not be fatal.
