　　Banana is one of the most common tropical and subtropical fruits in life. It is nutritious, delicious and affordable, and it is often eaten by many people. Banana tastes soft and waxy, suitable for all ages, and is rich in sugar, dietary fiber, vitamins and minerals, especially potassium. Eating bananas often can moisten the intestines and relax the bowels, and it is also beneficial to the health of patients with hypertension. And the study found that bananas contain substances that can make people "happy" and can relieve depression.

　　However, a rumor on the Internet makes people who love bananas very entangled. Can this banana still be eaten?

　　It originated from the news that farmers soaked garlic shoots and bananas in white liquid on the Internet in May last year, which aroused widespread concern among consumers. This year is also May, and see similar news.

　　Everyone is particularly concerned about what this banana-soaking liquid is? Can the soaked bananas be eaten? Is it harmful to health?

　　Some netizens speculated that it was formaldehyde solution, but it wasn’t. Agricultural experts explained this. The white liquid is a preservative, so consumers don’t have to worry.

　　Bananas grow "too anxious"

　　Banana belongs to respiratory climacteric fruit, which will suddenly release a lot of ethylene at maturity, and the respiration rate of the fruit will be greatly improved and mature rapidly. But then it quickly aged and was attacked by fungi.

　　Therefore, fruits like bananas cannot be picked, transported and sold after they are ripe. Because once the "ripening switch" is turned on, the banana will be unstoppable when it ripens, and it will be broken before it reaches its destination. For this reason, bananas have to be picked from trees before they are fully ripe, so that they can withstand long-distance transportation and long-term storage, and then artificially apply ethephon to ripen them before they are sold.

　　Why do you want to soak a good banana?

　　Picked bananas are prone to anthracnose or shaft rot-the name may sound strange, but most people have encountered it. Anthracnose shows that bananas grow dark brown black spots, and then quickly expand and merge, and within a few days the whole banana will turn black and rot.

　　Axle rot is commonly known as "white mold". At first, white mold appeared at the incision of banana comb and rotted, which continued to develop to the fruit stalk and was dark brown, causing the banana to fall off. Later, the whole banana became ill, and the peel cracked and the flesh degenerated. Therefore, it is necessary to sterilize and preserve the picked bananas to prevent mildew.

　　What you don’t know about banana "preservative"

　　At present, prochloraz and iprodione are the main fungicides used for banana sterilization and preservation, all of which are efficient, broad-spectrum and low-toxic. Prochloraz is often used to control anthracnose, leaf spot, rice bakanae disease and rice blast of fruits and vegetables, and iprodione is also often used to control early defoliation, gray mold and early blight of fruit trees, vegetables and fruits. Bananas treated with fungicides, combined with modified atmosphere fresh-keeping bags and low temperature, can play a good anti-corrosion and fresh-keeping effect.

　　In addition to fungicides, it is also possible to treat bananas with plant growth regulators to inhibit their ripening process.

　　Is banana preservative safe?

　　Prochloraz and iprodione are both low-toxic pesticides allowed in China, and the national food safety standard Maximum Residue Limits of Pesticides in Food (GB2763-2014) clearly stipulates the residue limits of various pesticides, such as:

　　The maximum residue limits of prochloraz and iprodione in bananas are 5mg/kg and 10mg/kg respectively.

　　Plant growth regulators, also known as phytohormones, are used to artificially regulate the growth and development process of plants, with low toxicity, small dosage and self-limitation. If they are used too much, they will not get good results.

　　Rational use of pesticides such as fungicides and plant growth regulators in accordance with state regulations will not cause harm to health. Therefore, the banana is still the banana, so just eat it boldly!

On March 5 th, a few days ago, the Radio Administration Bureau of the Ministry of Industry and Information Technology issued the announcement of "Radio Frequency Technical Requirements for Base Stations of 5G Mobile Communication Systems in 2100MHz Band (Trial)" (hereinafter referred to as "Trial Announcement").

According to the announcement, in order to meet the demand of 5G applications and ensure the compatibility and coexistence of China’s 2100MHz 5G mobile communication system and other radio services, according to Announcement No.80 of the Ministry of Industry and Information Technology of the People’s Republic of China in 2015 and Notice of RF Technical Requirements for Low and Medium Frequency 5G System Equipment (No.87 [2020] of the Ministry of Industry and Information Technology), the Radio Administration of the Ministry of Industry and Information Technology studied and formulated the Trial Announcement.

The announcement further cleared the way for the co-construction and sharing of China Telecom Unicom’s 5G network. This means that the dual-band 5G strategy previously formulated by China Telecom and China Unicom can be implemented aboveboard, and it also means that both parties can promote the collaborative innovation of the world’s widest TDD(200M) and FDD(2x40M) spectrum, maximize the spectrum benefits and realize.

At present, China has allocated relevant 5G frequency bands to the four major operators. As far as China Telecom and China Unicom are concerned, China Telecom got (n78), which is the 3.5GHz band (); China Unicom also got the 3.5GHz frequency band () on (n78). As can be seen from the allocated frequency bands, the frequency bands allocated by China Telecom and China Unicom on n78 are continuous, which is beneficial for the two companies to jointly build a 5G network.

It should be noted that, unlike the previous mobile communication network standards, the 5G network must cooperate with high, medium and low frequencies according to the user’s service coverage and speed requirements to form efficient and coordinated layered coverage. Wei Leping, executive deputy director of the Science and Technology Committee of the Ministry of Industry and Information Technology and director of the Science and Technology Committee of China Telecom Group, once pointed out that according to the existing distribution scheme, China Telecom and China Unicom only have 100MHz in the 3.5G band, and the uplink coverage of 3.5G band is 9dB and 5dB different from that of 1.8GHz and 2.6 GHz under the premise of the uplink edge rate of 3Mb/s, which leads to the uplink coverage of SA in the 3.5G band, and the uplink capacity and delay are difficult to effectively support vertical industry applications.

"The only way out is to deploy 2.1G/1.8G FDD system as uplink enhancement, cooperate with 3.5G, complement high and low frequencies, and aggregate in time-frequency domain, so as to have the network advantage and economic feasibility of turning to 2B in uplink coverage, uplink capacity, delay characteristics and even investment." Wei Leping said.

China Telecom and China Unicom’s 2.1GHz band have been used in 3G/4G networks for a long time. After the 5G was jointly built and shared, the two sides plowed the frequency band to deploy 5G and increased 5G coverage. It is reported that China Telecom’s 2.1GHz(Band1,n1),1920~1940/

2110~2130MHz was originally approved for deploying CDMA2000, which is 3G band. The actual CDMA2000 uses 825~835/870~880MHz, which is used to deploy LTE FDD.

China Unicom’s 2.1 GHz (Band 1, N1), 1940 ~ 1965/2130 ~ 2155 MHz: originally approved for deploying WCDMA, it is 3G band. Now it is mainly used to deploy LTE FDD, Unicom’s 4G important frequency band and 5G NSA networking anchor frequency band.

In the 2.1GHz band, the spectrum of both China Telecom and China Unicom is continuous, plus the continuous spectrum in the 3.5GHz band. The integration of resource endowments between the two parties has achieved the effect of 1+1>2, and doubled the scale, coverage, bandwidth and speed of the 5G network. It can be said that you naturally have a leading experience at birth.

In the past year, China’s 5G commercialization has taken solid steps. According to public data, by the end of 2020, operators have opened a total of 718,000 5G base stations, and the number of 5G mobile terminal connections has exceeded 200 million. According to the plan, about 700,000 new 5G base stations will be built in China this year.

Faced with the contradiction between huge market space and huge investment in 5G construction in the future, how to build a high-quality 5G network with wide coverage, high speed and good perception with high efficiency and low cost is a difficult problem for operators.

Without any experience to learn from, China Unicom and China Telecom boldly explored and pushed forward with all their efforts. On September 30th last year, they quickly completed the construction and commercialization of the world’s first-scale 5G co-construction and sharing network, and completed the end-to-end capacity deployment of SA independent networking mode.

By October 2020, the scale of 5G sharing between the two sides has reached more than 300,000 stations, covering all cities above prefecture level in China. It has achieved three "world firsts": the world’s first and largest 5G network; The world’s first 200MHz high-bandwidth high-performance 5G network; The world’s first 5G network with TDD+FDD hybrid networking. Through co-construction and sharing, the construction and operation costs of 5G networks will be significantly saved. CAPEX is expected to save about 40%, and OPEX will save about 35% every year, fully highlighting the advantages of co-construction and sharing.

The achievements of co-construction and sharing have laid the foundation for the development of the 5G market. In the next stage, both parties will focus on users and experience to create a high-quality 5G boutique network.

Miao Shouye, head of the working group of China Unicom’s 5G co-construction and sharing, once pointed out that a high-quality 5G boutique network should have three typical characteristics: minimalist network, extreme experience and extreme intelligent service.

"Minimalist network" is a clear minimalist target network to promote future construction, promote network slimming, realize intergenerational decoupling of standards through network resource integration, and let 5G go into battle lightly. Specific objectives include system minimalism, architecture minimalism and site minimalism.

In terms of minimalist standards, China Unicom is currently facing the situation of 2G to 5G four generations living under one roof, which is under great operational pressure. China Unicom hopes to finally form a 4G+5G cooperative minimalist target network.

In terms of minimal architecture, Unicom Telecom’s co-construction and sharing accelerated the evolution of NSA to SA architecture, simplified the complex network structure after the superposition of NSA and co-construction and sharing, and reduced the difficulty of tight coupling optimization of 4G and 5G dual networks; At the same time, SA architecture can support the digital development demands of toB industry. At present, China Unicom has taken the lead in drawing networks and terminals to open SA capabilities in many provinces, fully supporting the development of the toB market.

On the whole, China Telecom and China Unicom’s 3.5G+2.1G dual-band collaborative network construction strategy takes into account competitiveness and investment reduction, but it is still necessary for both the terminal and the network to support 2.1G NR, 2.1G and 3.5G dual-band CA and SUL, so as to ensure the success of the next large-scale commercial deployment of 5G networks.

1905 movie network news Produced and directed by the producer, starring Huang Xiaoming, Zhang Jiaxin and Wang Yinglu, the film released a special feature of "infighting" among actors, and a rare trial scene in Chinese film industry for many years also appeared. Huang Xiaoming’s trial drama is always a page or two of long lines output, which is extremely difficult to perform; Adi changed her lively and cheerful image, and performed a fair "cold-faced" prosecutor. At the same time, the two leading actors said that it is very difficult to start a forceful debate only by human voice in a huge shooting scene.

Huang Xiaoming repeatedly practiced the long lines of the trial play.

Adi’s Contrastive Interpretation of "Cold Face" Prosecutor

A few days ago, the film "The Last Truth" released a special feature of the actor’s "infighting", exposing Ding Yifeng, a defense lawyer played by Huang Xiaoming, and Sun Yu, a prosecutor played by Adi, behind the scenes of the court trial. In this shooting, both of them regard the lines of the trial play as the primary difficulty to break through.

Huang Xiaoming revealed: "This role has a lot of long lines of one or two pages, and some shots need to be seen to the end, so the whole scene must be performed in one go." In the special edition, we can see some NG pictures of Huang Xiaoming at the shooting scene, but after practicing and completing a wonderful performance, even the extras will send applause.

Adi also said that the prosecutor played this time has many professional legal terms in her lines, and she must not make a word wrong. To this end, she watched a lot of trial videos before shooting, and also learned knowledge with prosecutors in reality to observe their calm state of affairs. Regarding how to maintain a cool and dignified side and calmly respond to doubts and refutations in court, Adi revealed: "In fact, the contrast between this character and me is quite large, and the usual lively side has been suppressed during the performance. There can be no trivial actions, and more is to express the character’s heart with his eyes."

First Reveal the Past of Huang Xiaoming Adi’s Role "Fengyu"

The court will keep the old friends in suspense.

The announcement of the actor’s "infighting" special feature not only shows the fierce confrontation between lawyer Ding Yifeng and prosecutor Sun Yu, but also reveals from the side that the two were once brothers and sisters and were alumni. In the special edition, Adi revealed that Sun Yu and Ding Yifeng had met in the school debate before, and some of her behaviors after her employment were also influenced by the character Ding Yifeng.

As old friends and brothers and sisters in the past, many years later, because of the case of Jin Ximei, they once again fought in court as opposites. In addition to who will win the final trial, how the relationship between the two will develop has become another suspense of the story. Huang Xiaoming admits that Adi’s role is very important: "She is an important turning point in the reversal of this play. Adi’s role has made a great breakthrough, and her interpretation is also very good. Movies can’t be exaggerated. If you play the truth, the audience will be moved by your truth. "

The film The Last Truth will be released nationwide on December 3rd, 2021.

　　Beijing, December 7 (Reporter Li Jinlei) the Political Bureau of the Communist Party of China (CPC) Central Committee held a meeting on December 6 to analyze and study the economic work in 2022. The meeting set the tone for China’s economic development in 2022, including some new formulations, which release important signals and deserve attention.

　　Next year’s economic work should be steady and strive for progress.

　　How to do economic work next year? The general tone is very important. The meeting emphasized that,Next year’s economic work should focus on stability and strive for progress.

　　Compared with the previous year’s "striving for progress in stability", this time there are four more words: "Steady words are the first". What signal does this release?

　　Observers believe that more emphasis on steady growth is a realistic requirement under the new downward pressure on China’s economy.

　　The "Blue Book of Economy: Analysis and Forecast of China’s Economic Situation in 2022" released on December 6 pointed out that in 2021, under the situation of normalization of epidemic prevention and control, China’s economy generally showed a good recovery trend, but in the uncertain and unstable epidemic situation and external environment, the downward pressure on the economy increased, and there were many risks and challenges to maintain a stable economic operation. It is estimated that China’s economy will grow by 8.0% in 2021 and China’s economy will grow by about 5.3% in 2022.

　　Xu Hongcai, deputy director of the Economic Policy Committee of China Policy Science Research Association, said in an interview with the "China New Observation" column of Zhongxin.com that the downward pressure on the world economy is relatively large at present, and so is China’s economy. Therefore, to curb the downward trend, we must pay more attention to steady growth. In particular, the world economy is expected to slow down next year, and external demand will shrink. The good days of China’s foreign trade growth of more than 20% this year may be difficult to reproduce next year. Therefore, we must strive for progress in stability and strive to achieve high-quality development to calmly cope with the new international and domestic challenges facing the present and future.

　　Fiscal policy pays more attention to precision and sustainability.

　　The meeting stressed that macroeconomic policies should be sound and effective, and we should continue to implement a proactive fiscal policy and a prudent monetary policy.A proactive fiscal policy should improve efficiency and pay more attention to accuracy and sustainability. A prudent monetary policy should be flexible and moderate, and maintain a reasonable and sufficient liquidity.

　　Proactive fiscal policy and prudent monetary policy have not changed. However, fiscal policy clearly "pays more attention to accuracy and sustainability", which means that the focus has changed from the outside world.

　　Xu Hongcai believes that "precision" means more directional regulation and "drip irrigation", focusing on key and weak links such as small and micro enterprises, agriculture, rural areas and people’s livelihood; "Sustainability" means doing what you can, not over-leveraging, preventing too much debt and paying attention to preventing risks.

　　Feng Xuming, director of the Macro-Policy Research Office of the Institute of Quantitative and Technical Economics of China Academy of Social Sciences, told the reporter of "China New Observation" column of Zhongxin.com that under the current downward pressure on the economy, fiscal policy needs to continue to be active and improve its efficiency. On the one hand, we will continue to maintain an appropriate deficit scale and appropriately move forward the pace of fiscal expenditure; On the other hand, it is necessary to optimize the structure of fiscal expenditure, increase support for "two new and one heavy" construction, technological transformation, productivity greening and other fields, help the supply side to consolidate the foundation and cultivate the yuan through fiscal expenditure, and at the same time expand supply and improve quality in public services such as education, culture, sports, old-age care and medical care.

　　Promote the healthy development and virtuous circle of the real estate industry

　　For next year’s real estate, the meeting stressed that,It is necessary to promote the construction of affordable housing, support the commercial housing market to better meet the reasonable housing needs of buyers, and promote the healthy development and virtuous circle of the real estate industry.

　　The central government has made new changes in the real estate adjustment next year. Compared with last year’s "promoting the stable and healthy development of the real estate market", this time it has added a new goal, that is, a virtuous circle.

　　Yan Yuejin, research director of the think tank center of Yiju Research Institute, told the reporter of "China New Observation" column of Zhongxin.com that this statement is very important and is a signal to give clear support to real estate. It shows that the virtuous circle of the real estate market is crucial. A bad market will cause the risk of thunderstorm of housing enterprises, and the risk of housing enterprises will be passed on to buyers. Therefore, this "virtuous circle" is an important expression of the real estate industry chain and has a very strong signal significance.

　　Xu Hongcai believes that the real estate adjustment has been relatively large since this year, and some enterprises that blindly expanded in the past and were lax in financial discipline have stumbled in this adjustment. It is very important for the real estate market to gradually restore calm and stability and prevent ups and downs. After all, real estate plays an important role in the economy.

　　Feng Xuming said that some indicators such as real estate investment, sales and land transfer have shown signs of slowing down recently. It is necessary to carefully manage the real estate market in the fourth-and fifth-tier cities, do a good job in stabilizing housing prices and expectations, and avoid a hard landing. In particular, it is necessary to avoid excessive price reduction and promotion of real estate enterprises to supplement liquidity under the pressure of "three red lines", which will trigger downward pressure on housing prices in some fourth-and fifth-tier cities, and further aggravate the debt risk of the real estate industry.

　　Realize a virtuous circle of science and technology, industry and finance

　　In addition to real estate, there is also a virtuous circle that is also concerned.

　　The meeting stressed that science and technology policies should be accelerated, key core technologies should continue to be tackled, national strategic scientific and technological strength should be strengthened, and the dominant position of enterprises in innovation should be strengthened.Realize a virtuous circle of science and technology, industry and finance.

　　Xu Hongcai pointed out that to realize a virtuous circle of science and technology, industry and finance, it is necessary to change the fragmented state of the past three, and form a linkage. Scientific and technological innovation cannot be overemphasized, industrial transformation and upgrading can not be overemphasized, and it can not be overemphasized that finance can improve the multi-level financial service system and improve the effectiveness of financial services. However, it is the first time that the three forms a linkage and a smooth cycle.

　　Chen Daofu, deputy director of the Financial Research Institute of the State Council Development Research Center, recently publicly stated that China has reached a critical period when industry, science and technology and finance need to be transformed into a virtuous circle. Whether this cycle is established well or not is related to the quality and efficiency of China’s development in the new era. It may be the key to the future to form a virtuous circle among the three, and promote the cycle by building a platform.

　　Chen Daofu believes that in order to achieve a virtuous circle between science and technology, industry and finance, we need to "see" and "understand" each other. In the three fields of science and technology, industry and finance, many outstanding achievements are equivalent to "black boxes" compared with other fields. Therefore, in order to support scientific and technological innovation, finance should first "see" scientific and technological achievements, "understand" and evaluate their potential market value in the future. At this time, bridges are needed, that is, bridges between technology and industry, or between technology and finance, or between industry and finance.

　　Promoting the new birth policy has been effective.

　　The meeting pointed out that social policies should cover the bottom line of people’s livelihood.Implement the employment priority policy, promote the new birth policy to be effective, and promote the national overall planning of basic old-age insurance.Improve the system of providing basic public services in permanent residence.

　　In Xu Hongcai’s view, the meeting specifically mentioned "promoting the new birth policy to be effective", which is a bright spot. The implementation of the new birth policy is related to the long-term development of the Chinese nation. At present, the birth rate in China is not going up, which is a big problem. Therefore, it will have a profound impact on the medium and long-term economic and social development as soon as possible.

　　Recently, many places across the country have intensively revised family planning regulations, increased maternity benefits and extended maternity leave. Many provinces have extended maternity leave from the past 30 days to 60 days, and some provinces have extended maternity leave for 60 days or even 90 days, and increased parental leave.

　　As usual, the Central Economic Work Conference will be held soon after Politburo meeting of the Chinese Communist Party. By then, the context of China’s economic work in 2022 will be clearer. (End)

1905 movie network news Recently, the film official who has received much attention announced the news of the final file and the starring lineup. Later, some sharp-eyed netizens found that the latest actor ranking was different from that announced in 2019. Netizens said that it was "one time" before, but now it has become "three times". It turned out that "five times" was directly displayed at the last place in the actor list, which triggered everyone’s speculation about "escape" and "hot spots".

In this regard, "Feng Shen I" posted a message on the official social platform to respond to this matter, saying that "Feng Shen I" is only the beginning of a trilogy series, so the actor ranking is different from that of the overall trilogy published in the 2019 "Feng Shen Trilogy".

Subsequently, starring Bo Huang,, and Chen Kun forwarded the article and responded. Bo Huang said: "What the audience will always remember is the shining character, not where the name is written. Legend has it that Jiang Ziya didn’t end up on the list of gods. He is still Jiang Ziya that everyone likes. "

ChristianRandPhillips said: "There are three films in Feng Shen, and the ranking of actors in each film will be adjusted according to the story." Xia Yu shouted that netizens hoped that everyone would pay more attention to the film itself and would answer everyone’s doubts in the cinema.

Photo of Jiang Mengjie’s sun-baked dog

1905 movie network news Recently, Hua Dan Jiang Mengjie, a little popular, sent two groups of photos with his dog in succession on his personal social platform, and wrote: "hello, everyone, my name is bro, and I am a little boy in Virgo. Because Ma Ma likes black music, she gave me a strange name. From now on, I will go to Ma Ma’s house to make trouble. I hope she will not scold me." "Every day, we are a bro from Brooklyn, and the most important thing is that we also draw eyeliner."

Jiang Mengjie sent two Weibo sunning photos with his dog.

Hu Yuwei, a good friend, left a message in the comment area: "Cute as hell! ! ! ! ! ! 　bro！ ! ！” Fans also commented: "I actually envy a dog." "bro is not a little boy, and the eyeliner is really beautiful! Like a charming little sister. "

It is reported that Jiang Mengjie andHu YuweiThe co-produced TV series "In new york" is currently under intense shooting in Beijing, and it is expected to meet the audience in 2018. The film starring her and Cheney Chen is also being shown in major cinemas.

　　Author: Meng Fanhua (special researcher of Beijing Supreme Leader New Era Socialism with Chinese characteristics Thought Research Center and secretary of the Party Committee of Capital Normal University)

　　In 2021, the general offices of the General Office of the Central Committee of the CPC and the State Council issued the Opinions on Further Reducing the Students’ Homework Burden and Off-campus Training Burden in Compulsory Education, the core of which is to reduce the students’ homework burden and off-campus training burden in Compulsory Education. Recently, Beijing has vigorously promoted the flow of principals and teachers, which is an important measure to implement the "double reduction" policy.

　　Rebalancing of Core Resources Based on Good Governance in Education

　　The basic requirement of social equity is the reasonable and equal distribution of social interests, economic interests and other interests among all members of society. Education equity has the significance of starting point equity and is an important foundation of social equity. Promoting educational equity, guaranteeing citizens’ right to education, realizing the equalization of basic public education services and narrowing the educational gap between urban and rural areas, regions and schools are the basic requirements of educational equity.

　　Since the beginning of this century, China has successively promulgated a series of policies aimed at the unbalanced development of compulsory education, which directly points to the balanced development of high-quality educational resources oriented to educational equity. Various practical schemes, such as reforming weak schools, integrating urban and rural education, and running schools in groups, have been explored according to local conditions, and great achievements have been made, effectively promoting the high-quality and balanced development of compulsory education.

　　The governance of compulsory education is a systematic project, and ideas, systems, resources, courses, methods and property are all elements of this system. Good governance means promoting the organic linkage of various elements within the education system and the harmonious development between education and social environment, building a high-quality and efficient public service system, stimulating the endogenous motivation of the education system and realizing sustainable development, which is what we call "good governance". In the compulsory education resource system, all resources are very important, and the short-board resource demand of each school is not the same. The research shows that among all the resources to improve the quality of education and teaching, the principal teacher is the most critical resource. As the first resource of compulsory education, principals and teachers are also the main body of other factors. Grasping this key factor and taking it as a breakthrough will have twice the result with half the effort for optimizing the governance structure and realizing the balanced development of compulsory education with higher quality.

　　Under the background of "double reduction" policy, in view of the problems that the optimal allocation of principals and teachers in the past was not strong and the role played after the exchange was not prominent, Beijing and other places intensively issued relevant policies to promote the flow of principals and teachers with unprecedented efforts, attach importance to the effective connection with the practice of early education reform, go beyond the previous one-way make-up rotation and the rotation of school district groups in the region, and coordinate the resources of principals and teachers within and across regions, thus promoting the structural renewal of teachers’ disciplines, knowledge structure and teaching experience.

　　Re-optimization of the management system of principals and teachers based on systematic person orientation

　　In 2014, the Ministry of Education, the Ministry of Finance, and the Ministry of Human Resources and Social Security jointly issued the Opinions on Promoting the Exchange and Rotation of Principals and Teachers in Compulsory Education Schools in Counties (Districts), which proposed the management reform of "County Management and School Employment" for compulsory education teachers. In 2018, the Central Committee of the Communist Party of China and the State Council issued the Opinions on Comprehensively Deepening the Reform of Teachers’ Team Construction in the New Era, which proposed the implementation of compulsory education teachers’ "county management and school employment" and demanded "establishing the special legal status of public primary and secondary school teachers as national public officials". The implementation of these policies is based on the balanced development orientation of publicity and fairness of compulsory education, and the rigid system with clear value orientation restricts the spontaneous one-way flow of principals and teachers to solve the overall optimization problem of the education system.

　　"County-run school employment" means that principals and teachers of public compulsory education schools are under the unified management of the county government and move to compulsory education schools in the county regularly, which means that principals and teachers have changed from "school people" in a school to "systematic people" in the county compulsory education system and fulfilled the obligations of "special legal status of national public officials". Transcending the identity cognition of "single school people" means breaking the zero-sum thinking of either-or in the process of resource use, making resources flow and giving full play to the efficiency of resource use. The flow of principals and teachers, the most important thing is not the flow itself, but the birth of new growth points through the flow.

　　The re-optimization of the management system of principals and teachers is a systematic project, which needs the support of corresponding supporting systems. Various places are constantly exploring the design of the professional system of principals and teachers. The policy of super principals introduced in Beijing is a system that is linked with the flow of principals, and there are more professional systems of teachers, such as the teacher qualification certificate system. The establishment of these systems provides a basic system guarantee for the orientation of principals and teachers as "systematic people", puts forward new requirements for the extensive adaptability of professional teachers, and will also force the principals and teachers to further optimize the management system.

　　Re-adjustment of school culture based on educational sociality

　　Sociality is the fundamental attribute of education. Education shoulders an independent social function, and as an activity dedicated to transmitting scientific and cultural knowledge and social life experience, its purpose is to socialize people. The school culture is the sum of all kinds of characteristics such as spirit and material, intelligence and emotion in the school. The school culture is constructed by teachers and students, and it is a process of consciously designing, intervening and building all aspects of the school. The construction of school culture stems from the handling of various social relations, including the relationship between man and the natural environment, the relationship between people, the relationship between the past and the present, and the relationship between tangible and intangible. School culture has social attributes.

　　The purpose of school culture construction is to "humanize", and the key to realize the development of school culture is "human". This "human" change in the flow of principals and teachers will inevitably have an impact on school culture. The headmaster enters a brand-new school to work, and the teacher enters another relatively unfamiliar environment from a familiar environment, which will inevitably bring about the breaking and reconstruction of the relationship. Behind it is the collision of different cultures and values, and diversification, collision and exchange are important educational resources. The mutual recognition of cultures and the reconstruction of relations are themselves the process of educational socialization, which is conducive to promoting the process of students’ socialization.

　　The school is an independent and open system, and the school culture is also not isolated and closed. It should be studied and built with a broader vision and a more open pattern. The flow of principals and teachers has indeed moved the "cheese" of traditional school culture to a certain extent, and there will inevitably be corresponding cultural conflicts, but the conflicts are not terrible, so it is unnecessary to refuse the flow because of the cultural conflicts caused by the flow of principals and teachers. In fact, the generation of any kind of culture is a process of continuous construction, and it is often intentionally adjusted and then reconstructed.

　　Re-activation of Development Motive Based on Internal Ecology

　　Every school can be regarded as an ecosystem. According to the logic of talent cultivation, from the beginning of enrollment, curriculum teaching is supported by resources and other factors, and finally students finish their studies and graduate. In this ecological chain, the key to raising or lowering the niche lies in the quality of principals and teachers. Generally speaking, there are two aspects to improve the quality of principals and teachers. First, the professional quality of principals and teachers can be improved through multi-channel continuous learning. The second is to rationally allocate the team of principals and teachers, optimize the team structure and activate the endogenous motivation of the team.

　　The essence of implementing the exchange policy between principals and teachers is the reform of the supply-side structure of education, which can stimulate the endogenous motivation of principals and teachers through the redistribution and combination of high-quality resources. Generally speaking, the endogenous motivation sources of principals and teachers involve values, needs, cognition, ability, emotion, interest and other elements, which interact with each other to form the dynamic basis of principals and teachers’ communication. The introduction of policies is only the first step, and the matching of external requirements and endogenous motivation is the direction of the next step. From a deeper perspective, efforts need to be made in the following aspects: firstly, to stimulate the internal driving force of the development of principals and teachers, to provide more appropriate "culture medium" for principals and teachers, the government to build a policy system for principals and teachers to strive for "four haves", and the school to actively broaden the development space of teachers and form an environment to stimulate the development motivation of principals and teachers; Secondly, meet the reasonable demands of principals and teachers, provide personalized support for the problems caused by mobility, and solve the practical difficulties of principals and teachers; The third is to build a system and mechanism to support team building, strengthen the sense of cooperation, enhance the ability of principals and teachers to adapt to the new environment, and enhance the cohesion of the new team.

　　Guangming Daily (13th edition, January 4, 2022)

　　On May 7th, when he went to Belgrade for a state visit to Serbia, the Supreme Leader of president published a signed article entitled "Let the light of die-hard friendship light up the road of cooperation between China and Serbia" in Serbian Politburo. The full text of the article is as follows:

Let the light of hardcore friendship illuminate the road of cooperation between China and Serbia.

Chairman People’s Republic of China (PRC), Supreme Leader

　　On the day of Meng Xia, everything is beautiful. At this hopeful time, I will pay a state visit to the Republic of Serbia at the invitation of President Alec Sandahl Vucic. This is the second time that I have set foot on this beautiful and legendary land of Serbia since I became President of People’s Republic of China (PRC). The beautiful scene of visiting Serbia eight years ago is still vivid, and the close cooperation between the two sides has achieved fruitful results in the past eight years. I look forward to talking about friendship and cooperation with Serbian leaders and friends, such as President Vucic, once again, so as to inject new vitality into the die-hard friendship between China and Serbia.

　　China and Serbia are far apart, but the two peoples are always hand in hand. During the years of the anti-fascist war and the period of national construction in the last century, the people of the two countries cultivated deep friendly feelings across time and space. In the great changes that have never happened in the world in the past century, the two sides have become more firm in supporting each other, closer in mutually beneficial cooperation and deeper in exchanges and mutual learning. No matter how the international situation changes, China and Serbia are always true friends and good partners. Our die-hard friendship has lasted for a long time, setting a good example for exchanges between the country and the people.

　　We insist on mutual respect and trust. I have established a good working relationship with President Vucic through meetings, phone calls and letters. The two countries maintain close contacts at all levels and in all fields. The two sides fully understand and respect the development path chosen by their people, adhere to the principle of fairness and justice, firmly support each other’s core interests and major concerns, and coordinate and cooperate closely and smoothly in bilateral and multilateral fields. The comprehensive strategic partnership between the two countries has been deepening and deepening.

　　We insist on mutual benefit. Serbia is China’s first free trade partner in Central and Eastern Europe. Last year, China was the largest source of investment and the second largest trading partner of Serbia. The cooperation in economy, trade, industrial chain and infrastructure construction between the two sides is in the ascendant, helping the respective modernization processes of the two countries. In 2016, the Smederevo Steel Plant of Hegang, which I visited, has become one of the three largest export enterprises in Serbia. Serbian agricultural products such as honey, red wine, beef and mutton are deeply loved by consumers in China.

　　We insist on helping each other. After the outbreak of the COVID-19 epidemic, I spoke to President Vucic twice and reached an important consensus on anti-epidemic cooperation. China assisted Serbia and gave priority to providing many batches of medical protection materials, and also sent experts to Serbia. Serbia fully supported China’s "Spring Seedling Action" to help overseas Chinese during the epidemic, and Serbian non-governmental organizations spontaneously donated masks and other materials to the people of China. This kind of brotherhood is precious.

　　We insist on learning from each other. Both China and Serbia are committed to the pursuit of people’s happiness and national prosperity. The two countries actively exchange experience in governing the country and strengthen political party exchanges. The people of the two countries have a deep affection for each other, and cultural, sports, tourism and other cultural exchanges are warm. Serbian basketball star Jokic cheered for China and the American country basketball competition. The two countries are exempt from visas for ordinary passport holders, which facilitates personnel exchanges and exchanges and cooperation.

　　Chinese said, "Friends unite in righteousness". The Serbs said, "Friends are the best wealth in life". The long-term friendly exchanges and mutually beneficial cooperation between China and Serbia fully show that the continuous deepening and development of bilateral relations conforms to the historical trend, conforms to the fundamental interests of the people and is conducive to the common progress of both sides. In the new era and new journey, China-Serbia comprehensive strategic partnership has broad space for further development. Through this visit, I would like to work together with Serbia to carry forward the hardcore friendship between China and Serbia, and take concrete actions to better benefit the two peoples, promote world peace and development, and jointly promote the building of a community of human destiny.

　　We should always be good friends who treat each other sincerely. China and Serbia will deepen and expand the comprehensive strategic partnership. The two sides will continue to advance along the road of mutual understanding, mutual trust, mutual support and mutual assistance, and continue to give each other firm support on issues involving each other’s core interests and major concerns. China respects and supports the development path chosen by the Serbian people, supports Serbia’s efforts to safeguard national sovereignty and territorial integrity, and opposes any interference in Serbia’s internal affairs.

　　We should always be good partners for win-win cooperation. China is promoting Chinese-style modernization with high-quality development and accelerating the development of new quality productive forces. In recent years, Serbia has made remarkable achievements in economic and social development. China and Serbia should deeply tap the potential of mutually beneficial cooperation, implement the medium-term action plan for jointly building the "Belt and Road", strive to build more landmark projects, expand cooperation in emerging fields such as scientific and technological innovation, advanced manufacturing, green energy, digital economy and artificial intelligence, share development opportunities and create a better future.

　　We should always be a good example to promote fairness and justice. As die-hard friends and defenders of world peace, China and Serbia have similar positions on many major international and regional issues. Facing the turbulent international situation, we should strengthen coordination and cooperation in the United Nations and other international organizations, jointly advocate an equal and orderly world multipolarization and inclusive economic globalization, practice true multilateralism, and commit ourselves to maintaining world peace and stability and international fairness and justice.

　　We should always be good bosom friends who are connected with the people. The hard-core friendship between China and Serbia has experienced the tempering of blood and fire, and it has even glowed with new brilliance in the new era. We should create a three-dimensional and diversified pattern of people-to-people exchanges and local cooperation, make good use of the effect of "visa-free+direct flights", give full play to the role of mutual cultural centers, increase cooperation in education, sports, culture and tourism, create more opportunities for young people, and let China-Serbia friendship pass on from generation to generation.

　　At this moment, we can’t forget that 25 years ago today, NATO brazenly bombed China’s embassy in Yugoslavia, and three China journalists, Shao Yunhuan, Xu Xinghu and Zhu Ying, were killed. The people of China cherish peace, but they will never let the historical tragedy repeat itself. The blood-soaked friendship between the Chinese and Serbian peoples has become the common memory of the two peoples, and will also inspire both sides to stride forward together.

　　Looking back on the journey to Qian Shan, looking forward to Wan Muchun. Standing at a new historical starting point, we are willing to work together with Serbian friends to make progress in Do not forget your initiative mind, work together to create a new chapter in national development and revitalization, and build a community of destiny between China and Serbia in the new era. Let’s witness and expect the tree of China-Serbia friendship to grow sturdily and bear more fruitful results for the benefit of the two peoples.

Why can’t eBay and Amazon dominate Poland According to the analysis of Shopbetreiber-Blog, eBay didn’t play a big role in the Polish e-commerce market, and Amazon didn’t even set up a Polish station. Although Amazon has three logistics centers in Wroclaw, the fact that eBay lost to Allegro stopped Amazon in Poland. Foreign media said: "eBay, which entered Poland in 2005, is such an example. The well-known international giants lost to local competitors."

Allegro is so popular in Poland and has obvious advantages because it was established as early as 1999. After that, it continued to expand its business and eventually became a market giant in Poland.
