　　People’s Daily Online, San Francisco, April 20 (Han Shasha) Every Wednesday morning, the citizens of Fremont, San Francisco Bay Area, California, USA always push out three roller trash cans with different colors that are usually placed in the yard, and open them in front of the street in a row.

　　As the garbage trucks rumble past, these garbage cans placed on the street are classified, dumped and transported away.

　　Trash cans of different colors have their own uses. In this city, gray trash cans are used to hold renewable garbage, such as wine bottles, beverage bottles, cans, clean waste paper, etc. Blue trash can is used to hold non-recyclable garbage, such as leftovers, vegetable roots and peels and other kitchen waste; Green trash can is used to hold garden garbage such as weeds and pruned branches in the yard.

　　This is a microcosm of the classification of domestic waste in California. Although each city gives different "connotations" to trash cans with different colors, and the time for recycling garbage once a week is not the same, garbage sorting has been deeply rooted in people’s hearts and become a daily routine.

　　Specialized companies provide garbage collection services in a unified way.

　　The garbage classification system in the United States is a mature and perfect system, which includes not only the front-end classification carried out by residents in daily life, but also the back-end recycling, landfill treatment and degradation, so as to realize the reduction, harmlessness and resource utilization of domestic garbage.

　　Residents’ classification of domestic waste is the basis of the whole system engineering. Every city has a clear explanation, education and promotion activities for garbage classification. On the official website of the city, residents can consult various information such as specific garbage recycling plans and garbage classification. In addition to common household garbage, including toxic household cleaners, paint thinners, pesticides, fluorescent bulbs and tubes containing mercury, thermometers and thermostats, electronic waste and vehicle batteries, household harmful waste is not allowed to be put into the roadside roller trash can. Because domestic harmful waste contains toxic substances, if it is not handled properly, it will harm human beings and the environment. These harmful waste must be placed in the designated recycling place and cannot be discarded at will.

　　The sorted garbage is collected by a special garbage recycling company on a fixed date, and residents pay a certain amount of "garbage clearing fee" every month. Individuals are strictly forbidden to rummage through the available items in the trash can without permission, otherwise it will be treated as theft. There are more than 20,000 garbage recycling companies in the United States providing services to different cities. Take San Francisco as an example. Recology is a service company in this city. Residents receive three 32-gallon garbage bins free of charge, and pay the service fee of $35.18 per month to the company, which provides regular garbage removal service.

　　Usually, garbage recycling companies will reclassify domestic garbage in different ways and recycle it reasonably. Renewable plastics, metals, waste paper and glass will be sorted, recycled and reused; Burning combustible materials to generate electricity; Decomposable organic matter is fermented to make organic fertilizer; Inorganic waste is used to pave the road. In recent years, garbage recycling companies have reprocessed domestic garbage in a more optimized way, and often use organic garbage gasification to generate electricity; Pyrolysis and incineration of pollutants, incineration and heating, gasification and power generation, purification of water and gas residue, etc. According to the website of Luyuan Recycling Company, food waste in San Francisco was transported to a nearby factory and turned into valuable fertilizer. Some finished fertilizers are sold to vineyards in Napa wine country.

　　Residents who litter may go to jail.

　　The strict implementation of garbage sorting in the United States is inseparable from the government’s education and promotion and detailed laws and regulations.

　　The Resource Conservation and Recovery Act is the basic law for the management of solid and hazardous wastes in the United States. On October 21, 1976, the US Congress passed the law reform to deal with the growing problem of urban and industrial waste. This law is divided into three parts, which respectively put forward requirements for the management of solid waste, hazardous waste and underground storage of hazardous waste. The focus of this law is the control and management of hazardous waste. In order to cooperate with this law, the US Environmental Protection Agency has formulated hundreds of regulations, plans and guidelines on the discharge, collection, storage, transportation, treatment, disposal and recycling of solid waste and hazardous waste, forming a relatively complete system of solid waste management laws and regulations.

　　In addition to federal laws, each state also has its own laws and regulations. Littering is a crime in America. Every state has laws prohibiting littering, and littering is a third-degree misdemeanor, punishable by a fine ranging from 300 to 1,000 dollars, imprisonment or community service (up to one year), or a combination of two or three of the above.

　　San Francisco, California, USA has made remarkable achievements in garbage sorting, recycling and reuse, with a garbage recovery rate of 80%, which is called "green city in green state". Siemens conducted a study in 2011, and the results were published in the "Green City Index". By comparing the sustainable development performance of 27 major American and Canadian cities, San Francisco was rated as the greenest city in North America and ranked first in garbage management.

　　This result is closely related to the California government’s advanced environmental awareness and the promulgation of a series of bills. As early as 1921, the government of San Francisco required that garbage recycling must be managed by companies, and individual garbage recycling behavior should be banned, thus resulting in "Sunset Cleaning Company" and "Cleaners Association", which is now the Luyuan Recycling Company in San Francisco. In 1989, the city of San Francisco passed the "Comprehensive Waste Management Act (AB939)", requiring all administrative districts to achieve 50% waste disposal by reduction and recycling before 2000. Regional managers who failed to meet the requirements were fined $10,000 per day. At the same time, the household is taken as an independent individual to carry out classified garbage collection, and institutions regularly come to collect recyclable items, and the sales proceeds are used to cover the garbage disposal expenses.

　　According to this law, California has set up a "Unified Management Committee for Municipal Waste" to specifically guide and supervise the implementation of various tasks, with the aim of making people fully aware of the fact that municipal waste is increasing and landfill sites are becoming increasingly scarce.

　　With the passage of time, the San Francisco government’s laws on garbage recycling and classification have become more and more detailed, including the implementation of the "Waste Electrical Appliances Recycling Law" passed by California in 2003, which made specific provisions on the recycling of waste computers, televisions and other audio-visual equipment.

　　In 2009, San Francisco passed the "Compulsory Classification of Garbage", which stipulates that residents must strictly abide by the classification of discarded items, and it is strictly forbidden to rummage through the usable items in the garbage bins without permission, otherwise it will be punished as theft, and at the same time, different levels of fines will be imposed on each household that violates the rules. This was called the most stringent recyclable law in the United States by the media.

　　Why does San Francisco have the confidence to set the goal of "zero waste"?

　　In 2002, the San Francisco City Supervision Committee and the mayor passed a resolution, and it is planned that by 2010, the conversion rate of garbage recycling and composting will reach 75%, and by 2020, "zero waste" will be completely realized.

　　San Francisco is the first city in the United States to set the goal of "zero waste" of garbage, and it is also the first city to force the use of three-color trash cans for recycling and sorting garbage. In 2013, San Francisco has successfully converted 80% of domestic garbage into recyclable garbage or fertilizer.

　　In comparison, the garbage conversion rate in Los Angeles is 65% and that in Seattle is 50%. According to the data of the US Environmental Protection Agency, in 2014, about 258 million tons of domestic waste was generated in the United States, and more than 89 million tons of garbage was recyclable and compostable, which was equivalent to a recovery rate of 34.6%, and 136 million tons of garbage was landfilled. Internationally, at the end of 2013, the EU’s garbage recycling and composting conversion rate was 42%.

　　The success of the "San Francisco Experience" is related to the radical and harsh government policies of the city. In addition to the above-mentioned series of laws and regulations, this city is the first city in the United States to ban the use of polystyrene foam in food service (2006), requiring mandatory recycling of construction waste (2007), prohibiting free provision of plastic bags in pharmacies and supermarkets (2009), and implementing mandatory garbage recycling and composting classification for residents and enterprises (2009).

　　In addition, there is a public-private partnership garbage collection system. Luyuan Recycling Company, which serves the city of San Francisco, is a private enterprise. In the process of providing services to San Francisco, there was no bidding and no payment to the government. The monthly service fees charged to residents and the profits generated by garbage sorting belong to the company. In 2012, the city of San Francisco once held a vote, and planned to break down garbage collection into five businesses to bid separately. But at that time, this proposal was opposed by 77% of voters.

　　San Francisco’s garbage classification can be deeply rooted in the hearts of the people, and it is inseparable from the government’s efforts to promote it widely. In order to better implement waste sorting and achieve the goal of "zero waste" in 2020, the environmental protection department of San Francisco specially promotes the publicity and education activities of waste reduction and sorting among young people; Introduced the family design concept of environmental protection garden, founded the San Francisco environmental protection foundation and the San Francisco organic food community; And promote environmental protection organizations in San Francisco community college and universities in San Francisco; Through posters, newspapers, the Internet, public transportation and other media, the publicity and promotion activities of urban garbage control have been carried out for a long time.

　　Whether San Francisco can achieve "zero waste" in 2020 is still unknown, but at least some experiences of the city can be used for reference.

Before Ivey’s film, he pushed a popular science article on screen technology, which attracted everyone’s attention. Today, let’s pay attention to the "behind-the-scenes" that is related to the screening effect-the projector.

　

Film projectors have become a memory for most people, and today’s cinemas have already become the world of digital projectors. Let’s briefly talk about the development history of digital projectors.

Advances in chip technology and resolution

Digital film projectors can be divided into 4K, 2k and 1.3k (obsolete) according to the resolution from high to low, and the core part is the DLP chip.

　

The digital film projector that appeared at the end of last century and the beginning of this century is1.3K(1280×1024, about 1.3 million pixels) resolution.. Its architecture is a DLP projection system with a digital projector head in front of the light box of the traditional film projector, and its imaging device is the DLP CinemaTM DMD digital micromirror device of Texas Instruments (TI).

　

DP50 1.3K digital projector

DLP technology (digital light processing) is a technology developed by Texas Instruments based on DMD. DMD (digital micromirror) is also an imaging chip developed by TI, and it is also the core component of DLP. DMD consists of many small aluminum mirrors, and each micro mirror is called a pixel. Its working principle is that after receiving the image control signal, it drives the micro mirror to deflect within 15 degrees, reflects light, and finally forms an image. Digital film projectors and high-end projectors generally adopt RGB three-chip DLP technology.

　

With the development of chip technology,The first 2K (2048× 1080.21 million pixels)The projector came out at the end of 2003, which adopted the DC2K DLP CinemaTM DMD chip of TI company, which improved the image resolution and contrast. This eliminated the projector that originally used 1.3K chip.

　

DP100 and DP90 2K digital projectors

In 2005-2006, DCI (Digital Cinema Advocacy Organization) released the technical specification 1.0 of digital cinema system, and various digital cinema equipment manufacturers followed suit, and developed and produced projector products conforming to DCI technical specification. According to DCI standard, the pixels of digital cinema projectors should reach 2K or 4K. Projector manufacturer including DLP technology, Barco, CTV and NEC, as well as Sony adopt liquid crystal on silicon SXRD technology, have launched a series of products.

　

In 2009, TI released its second generation DLP digital film platform.DLP Cinema?　Series II (SII or Series 2 for short). S II not only supports all the functions of the previous generation SI platform, but also enhances the signal processing ability of the system, and conforms to the DCI Digital Cinema System Technical Specification 1.2 in application.

　

In 2011, based on DLP Cinema? 1.38 "(inches).DMD 4K chipThe resolution reached 4K (4096× 2160,825 million pixels). In addition, in order to meet the needs of more small screens, the advent of 0.69 "DMD2K chips based on DLP Cinema has led manufacturers to launch DLP large projectors and small projectors based on these chips. With the advent of DLP4K projector, digital projection is comparable to 35mm film projection in definition, and the overall projection visual effect is better.

　

2019 4K global blockbuster "Maleficent: Mistress of Evil"

In 2013, TI (Texas Instruments) DLP Products Division launched a new breakthrough pixel architecture for its leading DLP Pico? technology.TIlt Roll Pixel（TRP）. The main advantages of products based on the new TRP pixel architecture include:

Improve brightness by up to 30% and higher efficiency; Energy saving by reducing power consumption by up to 50%; Twice the resolution of chips of the same size, and so on. For example, the s4 series of Barco’s fourth-generation projector is the latest series of digital projector products that take the lead in adopting 3×0.98” DC4K TRP chip, which can save more energy and further improve the degree of integration.

Progress in architecture and automation

The innovation of digital projection technology makes the control of equipment more and more automatic and intelligent.

　

Due to high integration and strong sealing performance,Heat dissipation and dust preventionIt is the most difficult problem of projectors in the past. In the past, when solving these two problems, the projectionist was particularly required to maintain the projection equipment in peacetime, but with the upgrade of the projector, the handling of these two aspects has now become simpler and more convenient.

　

The heat dissipation of the projector mainly surrounds the light source, chip and circuit. These places are easy to accelerate aging or damage if the heat dissipation is not in place, and attention should be paid not to have any dust when cooling. For example, high-precision core components such as chips cannot be polluted by any dust.

　

Now there are several ways to cool the projector:Air cooling, liquid cooling, and semiconductor cooling.. Air cooling mainly depends on the cooling channel designed in the projector; Liquid cooling is mainly aimed at the internal heat dissipation of the engine, and there is a set of liquid cooling heat dissipation system composed of liquid tank, pressure pump and heat exchanger in the projector. Semiconductor cooling, like using "Peltier" thermoelectric semiconductor refrigeration device.

　

Barco s4 projector series inherits the consistently efficient integrated cooling system of liquid cooling+air cooling+Peltier, and with the fully enclosed engine and light path design, the new double-layer HEPA washable filter screen can achieve the ultimate dustproof and efficient cooling effect. At the same time, the modular design of S4 series and brand-new network control and analysis software make the daily maintenance and repair of projectors easy, which greatly reduces the labor cost of daily operation and maintenance.

　

In addition to the continuous improvement of automation level, the projector architecture is also constantly optimized. From the original independent external server to the integrated media module IMB, to today’s integrated media server with higher integration.IMSsSome even integrate audio decoding module, which has higher integration and improved performance.

　

For example, in March, 2014, Barco first launched a product equipped with Lingrui.ICMP(Integrated Cinema Media Processor integrated media module) integrated projector of server. The ICMP module of Barco Lingrui skillfully integrates the digital movie image signal processor (ICP) with the media server responsible for the decoding function of DCI movie programs, which improves the simplicity and reliability of the projector. Intelligent projectors equipped with Lingrui ICMP can even detect potential operational errors and warn users when potential failures occur.

　

ICMP server

The historical origin of digital projector from the initial independent external server to the integrated media module IMB to the integrated media server IMSs with higher integration now comes from the actual demand of the film industry for higher image quality, higher frame rate and higher resolution. In the technical field of projectors and media servers, this can be summarized as follows,Need to pass a higherbandwidthTo process and transmit image data. This has become the driving factor of digital projectors from independent servers to IMBs(Integrated Media Blocks) and then to IMSs (Integrated Media Server) from 2005 to 2012.

　

In addition, in recent years, digital projectors are constantly strengthening their targeting.Automatic maintenance and optimization technology of laser light source and automatic image optimization technologyWith the passage of time, the white balance of the three-color laser light source of the projector is guaranteed and the color reproduction is better; The final imaging quality of the optical engine has been kept at a good level for a long time.

Progress in technical indicators

The technical progress of projector naturally promotes the improvement of its related technical indicators, so as to adapt to the landing of new projection technology.

　

For example, adapting to high frame rate projection, adapting to HDR (high dynamic range) image optimization, etc., requires a higher projectorBrightness, contrast, clarity and high color depth processing circuit, at the same time haveHigh frame rate projectionFunction.

　

The 1.3k machine adopts the 1.1 "/0.9" (inch) DLP CinemaTM DMD chip of TI company, with the contrast ratio of 1350: 1 and the deflection angle of DMD micromirror of 10. The final light output is about 6,000-13,000 lumens, and its light efficiency is relatively low, with the average light path light efficiency of 1-2 lumens/watt. At first, the 1.3k machine can handle Bit depth.

　

The second generation projector chip (DC2K DMD chip) comes in 1.2 "(inch) and 0.98" (inch), which were released by TI in 2003 and 2007 respectively. Compared with the 1.3 K chip, DC2K DMD chip increases the deflection angle of DMD micromirror by 12, making its contrast ratio more than 2000∶1. The light output of 2K projector can reach 30,000 lumens, and the color depth can reach 15 bits ×3. Moreover, the support for secure encryption/decryption, from supporting Cine I to supporting Cine II, meets the strict requirements of digital cinema for content security protection.

The 4K digital projector based on DLP Cinema? 1.38 "(inch) DMD chip has a brightness of 32,000 lumens and a contrast ratio of more than 2,100: 1.

　

S4 series projectors

Now the projector has a higher level of indicators. On BIRTV in 2020, Barco introduced the high-brightness RGB laser projector SP4K-40B with 40,000 lumens in the fourth-generation projector family, and introduced the RGB laser projector SP4K-55B with 52,000 lumens in CinemaS in 2021. In this fourth-generation projector family, the contrast ratio can reach 5,000: 1 like SP4K-27BHC.

　

In addition, with the improvement of light source, RGB laser projector has also improved the color range of the picture from DCI-P3 to.Rec2020, the color range is expanded by about.thirty percentFinally, due to the replacement of TI DLP technology, the fourth generation projector of Barco, which currently adopts the latest technology of TI, also has the ability to play.4K high frame rateThe ability of (high frame rate means > ＞24fps) greatly exceeds the original traditional signal format. Although there are not many such movies, the projector hardware is still ahead.

　

It can be said that the projection visual effect provided by the current digital projector has far exceeded the film projector era, providing a better viewing experience to a greater extent, and at the same time bringing higher intelligent automation to the operation, use and maintenance optimization of the cinema, making the cinema have a wider choice for different screens, different technical requirements and automatic projection, and greatly enhancing the security of film copyright!

　　In our country, most urban communities are composed of closed communities composed of high-density assembled houses, and each community is inhabited by thousands or even tens of thousands of people. With the intensification of population mobility, the community composed of strangers is completely different from the traditional rural community, and it is also different from the unit compound based on colleague relationship. Here, the binding force of acquaintance social rules is greatly weakened, and the large-scale and high-density living style makes various contradictions and disputes increasingly high, and new governance mechanisms and models need to be established urgently.

　　It seems that all kinds of contradictions and disputes in the community are mostly small problems, but in fact, the small problems that have accumulated over time and repeatedly have had a great impact on the living quality and living standards of the people. At the moment when the city is pursuing connotative development and vigorously improving people’s sense of happiness and gain, the community where we live every day should not become a forgotten corner and let "wrangling" be staged from time to time.

　　To this end, the editorial department of the semi-monthly talk organized reporters to go to Sichuan, Hainan, Jiangxi, Yunnan and other places to conduct research from three dimensions: residents and property, residents and community services, and sort out three major dilemmas: unbalanced rights, out-of-control disputes and service disability, which will serve as a pulse for the management of residential quarters.

　　Thematic planning and editing: Yuan Bixia Xu Xicai

　　The dilemma of "three lost" in urban community — — Unbalanced rights: how can the owners win when fighting with the property?

　　Half-monthly talk with reporter Zhao Yeping, Lu You, Yi Xuru

　　Compared with organizations, individuals are always in a weak position. This is reflected in the contradictions in the community. Residents in the scattered community can’t have an equal dialogue with the property company at all, and some behaviors of the property company are obviously unreasonable, so they can only bear it. If this imbalance persists, some contradictions and disputes will accumulate, which may even lead to mass incidents.

　　"Buy a suite with your life savings, and then spend money on the property to toss yourself!" Some owners have issued such a sigh.

　　Property VS Residents: Highlighting Five Contradictory Focuses

　　In almost every community, there are contradictions between residents (including owners and tenants) and property in one way or another. According to the statistics of 12345 citizen service hotline in Haikou City, Hainan Province, in 2017 and 2018, the hotline complaint type data ranked first, and most disputes originated from inadequate community management and chaotic charges. Government departments spend a lot of administrative resources to deal with these disputes, but they often end up without results.

　　Half-monthly interviews with reporters found that the current contradiction between residential residents and property mainly focuses on the following aspects.

　　Focus 1: Property charges rise at will, and owners default from time to time.

　　Recently, a residential property company outside the South Fifth Ring Road in Beijing informed the owners that the property fee rose from 2.18 yuan to 2.68 yuan, which triggered some owners’ resistance. "The property company claimed that after telephone and household consultation, it reached a unified opinion with most owners, but in fact some owners did not know." The owner, Mr. Chen, said that the property also held a "revenue and expenditure briefing meeting", but the accounts were not audited by a third party and were unconvincing.

　　A property manager told a reporter who talked for half a month that property is a small profit industry. Many times, once the owner delays paying the property fee, it is easy to cause the enterprise to lose money. So sometimes, in order to ensure their own interests, some property companies will force owners to pay by stopping handling water and electricity bills.

　　Focus 2: Public infrastructure needs to be repaired and replaced, but the cost is unclear.

　　Since 2016, located in a residential area between the First Ring Road and the Second Ring Road in Chengdu, elevators often break down. In April this year, the property company in the residential area posted a notice saying that the property company had funded the maintenance of elevators for several years, and the maintenance cost reached 425,000 yuan. This news caused some owners to question. Liu Jiabin, deputy secretary of the Party branch of the community, told reporters in half a month that at that time, some owners felt that the maintenance fund of 971,000 yuan had been used in the past three years. Why did it generate more than 400,000 yuan in advance expenses?

　　Focus 3: Community public assets are abused for profit, and the income and expenditure are unknown.

　　There are some assets owned by the owners in the community, and property companies often use them to obtain income without the owners’ knowledge or consent, and the whereabouts of expenditures are unknown. Take advertising revenue as an example. Most of the light box advertising and elevator advertising resources in the community are sold by property companies to advertisers, but the revenue is rarely announced to the owners, and most owners don’t know where the revenue is used.

　　An owner of Lehuo Gongyuan City Community in Nanchang City, Jiangxi Province told reporters that there are 10 buildings in the community, each with two stairs and three billboards in each staircase. The owner directly removed the advertisement of the building where he lived, and the property was monitored to find the owner. The owner believes that the elevator is a public space and cannot be used for elevator advertising, and requires the property to announce the use of billboards. Finally, the property did not install billboards in this elevator, and never gave relevant financial information.

　　Focus 4: Parking charges are chaotic and management norms can’t keep up.

　　With the popularization of urban cars, parking spaces are becoming scarce resources. In many cities across the country, such as Beijing, Shanghai and Chengdu, it is not uncommon for some property companies to raise the price of parking spaces at will. Disputes caused by parking chaos and parking difficulties are staged almost every day in some communities. "There are always other people’s cars parked in the parking spaces that my family pays for." Mr. He, who lives in Binjiang Community, Hanzhong City, Shaanxi Province, said, "The property always says that it should be standardized, but there has been no movement."

　　Focus 5: The collection of water and electricity charges failed to facilitate the people, but instead "pitted the people".

　　In some communities, residents’ utilities are collected by the property, which is a good thing for the convenience of the people. However, due to management loopholes or abuse of charging power in some property companies, many disputes have arisen.

　　Xin Chen, director of the industry committee of Fuxiang Jiayuan Community, Haikou City, Hainan Province, still remembers that once the property management company of the community used the water and electricity fees paid by the owners to pay their employees, and the water supply company and power supply bureau that were owed water and electricity fees often "stopped supplying water" and "cut off electricity" to the community, so the owners had to stay in hotels in married with children. Some owners who know what happened blocked the door of the community and refused to let the property manager leave, "forcing" him to solve the problem.

　　The establishment of the operation industry Committee faces

　　"eighty-one difficult"

　　Why are contradictions and disputes frequent? Insiders and grassroots cadres believe that the fundamental reason lies in the imbalance of rights between property and owners. Without an effective owners’ meeting and industry Committee, the owners are like a mess. Hiring a property company, dealing with the relationship with neighborhood committees and protecting the rights and interests of owners are all difficult to express their opinions, and there is also a lack of channels and platforms to solve problems.

　　According to a survey conducted by reporters in the past two months, although property management measures have been introduced in various places in recent years to encourage the establishment of industry committees in residential quarters, many industry committees in residential quarters have suffered from "dystocia" or even "abortion" due to the unfamiliar policies of owners, contradictions between owners and property companies, low social trust of strangers, and too complicated establishment procedures. Under the game of interests of all parties, the establishment of operation committee is facing the "eighty-one difficult".

　　According to Article 12 of the Regulations on Property Management in the State Council, the formulation and revision of the rules of procedure of the owners’ congress, the election of the owners’ committee or the replacement of the members of the owners’ committee, the selection and dismissal of property service enterprises, etc. shall be subject to the consent of the owners who account for more than half of the total building area and more than half of the total number.

　　"Hundreds of households and thousands of households should reach ‘ Double half ’ (More than half of the area and more than half of the owners) is very difficult. " Xiao Jiangtao, president of Haikou Owners’ Committee Association, said that some communities in Haikou have struggled for nearly 10 years and failed to set up industry committees.

　　According to reports, the proportion of the establishment of the industry Committee in Haikou Community is only 13.4%, and the proportion of the establishment of the national community industry Committee is not high, and the proportion in Beijing is only 25%.

　　Xiao Jiangtao believes that the deep-seated reason for the difficulty in the establishment and operation of the industry Committee is that the competent government departments are unwilling to intervene, do not know how to intervene, and have no ability to intervene.

　　According to an industry insider, according to the current law, street offices and township governments have the responsibility of guiding and supervising the establishment of industry committees in communities, but in fact, guidance and supervision have become examination and approval. Because this work is not linked to the political achievements of streets and towns, it can be done or not, and it is thankless, so it often becomes resistance rather than help.

　　In addition to being unwilling to guide and supervise, the competent government departments still have the problem of being unable to guide and supervise. Take Haikou as an example, there are 4 people in the Property Department of the Housing and Construction Bureau of Haikou City, and one deputy director of the residential insurance center in each district is in charge of the property. There are dozens of communities in each district, and there are no full-time property management personnel in the street office.

　　"The community only maintains stability, and it doesn’t matter if it doesn’t go wrong." A person in charge of the community industry Committee said that the neighborhood Committee will come forward to repair the road water in the village, but the road water in the community can only be responsible by the community itself. In 2018, the community built a cultural and sports activity center, and the industry Committee didn’t have enough funds, so it sent representatives to the neighborhood Committee and the street office to apply. The answer was: "How are you qualified to come to us for money?"

　　Owners "fight alone" when preparing for the establishment of the industry committee. After the establishment, the industry committee is still "fighting alone". How to negotiate with the property company and how to formulate the rules of procedure are all left to the members of the industry committee to explore. Those with strong ability will be handled well, while those with poor ability will often be "criticized" by the owners. As volunteers, the members of the industry committee serve the community free of charge and are under great physical and mental pressure.

　　Xiao Jiangtao said that the main reason why it is difficult to establish and carry out the work of the industry committee is that the industry committee is a new thing, and China’s commercial housing has only developed for more than 20 years now. "As an individual, the owners now have to work with corporate enterprises such as property and developers ‘ Fight for benefits ’ , even if it is the interests that originally belonged to the owner, it was strongly attacked because it broke the previous interest circle ‘ Fight back ’ 。” (Participating in writing: Yao Ziyun)

Beijing, December 6 (Xinhua) The biggest highlight of this year’s medical insurance negotiations is the suspense brought by the participation of more than 20 domestic innovative drugs in the negotiations.

On December 3, the new medical insurance catalogue of the National Medical Insurance Bureau was officially released. Rongchang Bio, which promoted two "world-class domestic innovative drugs" independently developed at one time to the medical insurance catalogue, immediately became the focus.

Taita Xipu (trade name: Taiai? ), vidiximab (trade name: Aidixi? ) was conditionally approved for listing by National Medical Products Administration (NMPA) in March and June, 2021 respectively. The former is the world’s first "dual-target" biological new drug for the treatment of systemic lupus erythematosus, and the latter is the first original antibody-coupled (ADC) drug in China. It is these two innovative drugs that have been approved to enter the medical insurance catalogue this time.

In less than half a year, two world-class original new drugs have been approved for listing; Just a few months later, two new drugs entered the medical insurance catalogue at the same time. Rongchang Bio’s innovation ability, product quality and commercialization speed are once again presented.

China’s self-developed world-class new drug "quickly" reduced the price into medical insurance

Why do innovative drugs get attention when they enter the medical insurance catalogue? Because this means the opening of a new life channel for patients with corresponding indications. Pay a lower fee, use the world’s leading new drugs and good drugs, and stay away from "poor diseases".

In fact, according to preliminary estimates, the adjustment of the national medical insurance drug list in the past three years, compared with the pre-negotiation market price, has reduced the burden on patients by nearly 170 billion yuan and benefited 100 million patients through negotiation price reduction and medical insurance reimbursement.

"The two pioneering new drugs, Taitacip and Vidicotuzumab, are quickly reduced in price into medical insurance, which can improve the accessibility of these two world-class biological new drugs in the country, help China’s over one million patients with systemic lupus erythematosus and the vast number of patients with gastric cancer to get effective treatment, reduce the economic burden of patients and their families, and better play the social benefits of drugs." Dr. Fang Jianmin, CEO and chief scientific officer of Rongchang Bio, said.

Systemic lupus erythematosus patients and other first domestic innovative drugs.

Systemic Lupus Erythematosus (SLE) is a lifelong systemic immune disease, which can cause damage to kidneys, cardiovascular system, lungs, digestive system, blood system, blood vessels, eyes and other organs and tissues, and significantly increase the risk of death of patients. Its harm makes people talk about it. According to "Guidelines for Diagnosis and Treatment of Systemic Lupus Erythematosus in China in 2020", there are more than 1 million patients with systemic lupus erythematosus in Chinese mainland, and the prevalence rate is the second highest in the world.

However, for a long time, a large group of patients have been faced with the dilemma of drug use-traditional glucocorticoids, immunosuppressants, etc. are often accompanied by great toxic and side effects, which are unbearable for patients. At the same time, it is difficult to "breed" new therapeutic drugs. In the past 60 years, the US Food and Drug Administration (FDA) only approved a drug for the treatment of systemic lupus erythematosus in 2011 (Berizumab developed by GlaxoSmithKline).

Rongchang Bio was included in the national medical insurance drug list this time, which is tetasip for injection (specification: 80mg/ piece). It is the first innovative drug approved in the treatment of systemic lupus erythematosus in China, and it is also the first-in-class biological drug in the world.

Different from the single-target design of listed drugs, the "double-target" design of Tatasip can inhibit BLyS and APRIL, two key factors that make B lymphocytes differentiate and mature at the same time, which can reduce the immune response of the body more effectively and play a "two-pronged" effect on treatment. The key clinical data showed that the systemic lupus erythematosus response index (SRI) in the high-dose group was significantly higher than that in the placebo control group (79.2% vs 32.0%) after 48 weeks of treatment, and the improvement of SRI was significantly better than that of the new biological drugs currently on the market. At the same time, the macromolecular drug Tetasip can be metabolized directly through cells, instead of liver and kidney metabolism, which can significantly reduce the side effects of traditional drugs and has higher safety. In a word, as a new drug with new target, new structure and new mechanism, Tetasip brings infinite new hope to the global SLE medical field.

Professor Zhang Fengchun, the head of clinical trial of Taitacip and the chief physician of Peking Union Medical College Hospital, said: "Compared with the existing treatment methods, the main therapeutic indexes of Taitacip have been greatly improved, which is a major breakthrough in the treatment of systemic lupus erythematosus, marking that China has taken the lead in the field of research and development of new drugs for the treatment of systemic lupus erythematosus. The inclusion of this drug in the national medical insurance drug list will further improve the accessibility of drugs, greatly reduce the medical burden of patients with systemic lupus erythematosus, and bring them higher quality survival benefits. "

Tetasip’s innovation has been recognized internationally, and its invention patents have been authorized by China, the United States, Europe and other countries and regions. Besides the indications of systemic lupus erythematosus, domestic and international clinical trials of Tatasip for neuromyelitis optica spectrum diseases, rheumatoid arthritis, IgA nephropathy, Sjogren’s syndrome, multiple sclerosis and myasthenia gravis are being conducted in an orderly manner.

To fill the blank of back-line therapy for gastric cancer patients with HER2 overexpression in China.

Another new drug of Rongchang Bio, which is included in the medical insurance catalogue, is vidiximab for injection (specification: 60mg/ piece), which is approved for patients with locally advanced or metastatic gastric cancer (including adenocarcinoma of gastroesophageal junction) who have received at least two systemic chemotherapy (HER2 immunohistochemical results are 2+ or 3+).

In China, gastric cancer is the second largest cancer species after lung cancer, with an annual incidence of 400,000, ranking first in the world. The morbidity and mortality are both high. 80% of patients with gastric cancer in China were in advanced stage when they were diagnosed. For most patients with advanced gastric cancer, chemotherapy is still the first choice for first-line treatment in the past few decades. However, the therapeutic effect of chemotherapy is limited, and the side effects are great, and the precise drugs for patients with gastric cancer who overexpress HER2 are even blank.

According to the latest data, the objective remission rate (ORR), disease control rate (DCR), median progression-free survival (PFS) and median overall survival (OS) of patients with HER2 overexpression gastric cancer treated with vidicon were 24.8%, 42.4%, 4.1 months and 7.9 months, respectively, which showed higher efficacy and better safety.
Therefore, China’s first original antibody-coupled (ADC) drug, vidiximab, developed by Rongchang Bio, went on the market, which filled the blank of back-line treatment for patients with gastric cancer whose HER2 was overexpressed in China.

As an ADC drug, vidiximab has the characteristics of antibody targeting and small molecule drug killing, and can accurately identify and kill tumor cells by targeting HER2 protein on the tumor surface. It has achieved world-leading clinical data in clinical trials for treating gastric cancer, urothelial cancer, breast cancer and other tumors.

Professor Shen Lin, vice president of Peking University Cancer Hospital, director of the Department of Gastroenterology and Oncology, and deputy director of Beijing Institute of Cancer Prevention and Treatment, said: "When vidiximab is featured by a wider range of treatment beneficiaries, a more balanced curative effect, safe benefits and a more economical and convenient detection process, and it has made revolutionary progress in the history of anti-HER2 treatment for gastric cancer, it is also inevitable that it will be highly recognized by National Medical Products Administration and the National Medical Insurance Bureau."

At the press conference on the adjustment of the national medical insurance drug list in 2021, Professor Shi Yuankai of the Cancer Hospital of China Academy of Medical Sciences mentioned that vidiximab is the first original antibody-coupled drug in China, and it has achieved good results in tumors such as gastric cancer and breast cancer. It is effective not only for patients with overexpression of human epidermal growth factor receptor -2(HER-2), but also for patients with low expression of HER-2. This time, the price of vidiximab was successfully reduced and entered the medical insurance, which benefited more cancer patients and filled the gap in the guarantee. While improving the drug guarantee for gastric cancer to the international mainstream drug use level, the burden on patients was greatly reduced.

Like Tatasip in the treatment of systemic lupus erythematosus, Videcituzumab is highly recognized internationally: this new drug is the first ADC drug in China that has been recognized as a breakthrough therapy by both FDA of the United States and NMPA of China. In August, 2021, Seattle Gene, an internationally renowned biopharmaceutical company, obtained the global (except Asia-Pacific) exclusive license agreement for vidicon with a down payment of up to US$ 2.6 billion and milestone payment, and a gradient sales commission of more than 15%. The transaction volume set a new record for overseas authorization of a single product of China pharmaceutical companies.

Innovative drugs are included in medical insurance, and the volume will obviously drive more innovations.

The medical reform in China continues to deepen, and the time for innovative drugs to be included in medical insurance has been greatly shortened.

The Blue Book on the Progress and Effectiveness of Medical Insurance Drug Management Reform shows that among the 34 innovative drugs listed from 2016 to 2020, 26 drugs have been included in the medical insurance catalogue, accounting for 76.5%. At the same time, in 2017, the time required for new drugs from listing to inclusion in medical insurance will be shortened to 1-8 years in 2019 and further reduced to 0.5-5 years in 2020.

The speed at which Rongchang Bio’s two innovative drugs entered the medical insurance is also a proper "top student". The characteristics of the two innovative drugs, such as "initiative", remarkable clinical effect, better safety and huge patient group, all escort their rapid inclusion in the medical insurance catalogue.

As for the new drugs with good curative effect, strong innovation and large clinical demand, it can quickly expand the sales channels and greatly increase the sales and market share of new drugs in a short time.

For example, according to the Blue Book on the Progress and Effectiveness of Medical Insurance Drug Management Reform, the dosage and amount of 17 kinds of anticancer drugs successfully negotiated in 2018 increased by 25.8 times and 8.8 times in the first quarter of 2021 compared with the first quarter before the negotiation (the third quarter of 2018); In the first quarter of 2021, compared with the first quarter before the negotiation (the fourth quarter of 2019), the amount of drugs successfully negotiated in 2019 increased by 10.4 times and the amount increased by 2.7 times.

Rongchang Bio-Tatasip and Vidicotuzumab are aimed at "a wide range of clinical unmet needs". With the opportunity of entering the medical insurance drug list, these two heavy new drugs may achieve rapid volume increase and gain more market share and economic benefits. And these will eventually lead to more innovations.

With the continuous introduction of policies to encourage innovation, such as accelerating the review of new drugs and normalizing medical insurance negotiations, enterprises that focus on early accumulation, do not blindly follow the trend of project establishment, and closely focus on how to solve the actual clinical needs are bound to stand out.

Rongchang biology is one of them.

Rongchang Bio, founded in 2008, has been focusing on the discovery, development and commercialization of antibody drugs such as antibody drug conjugate (ADC), antibody fusion protein, monoclonal antibody and bispecific antibody. At present, Rongchang Bio has developed more than 20 candidate biopharmaceutical products, and more than 20 indications of 7 products are undergoing clinical trials or have entered the commercialization stage.

In the best era of the development of innovative pharmaceutical companies, inclusion in the medical insurance catalogue has just begun for Rongchang creatures with outstanding research and development capabilities and rich reserves.

■ On June 7th, the college entrance examination officially kicked off.

On the first day of the college entrance examination, 23,800 examination rooms in the province were officially opened.

On the 7th, the national college entrance examination in 2019 officially kicked off, and over 10 million candidates went to the examination room. This year, Guangdong has set up 470 test sites and 23,800 examination rooms in 21 cities, and 685,000 candidates took the college entrance examination on June 7 and 8. Among them, there are 55 test centers in Guangzhou, and 2087 test centers have been opened, and 58704 candidates have signed up for this cultural examination.

The first day of the examination coincides with the Dragon Boat Festival. On that day, the weather was beautiful, the admission order of the whole province was good, the first day of Guangzhou college entrance examination was smooth and smooth, and the examination style and discipline were good. It is reported that in order to take care of "special candidates", 99 spare test rooms were opened in the whole province that morning, and Braille test papers were used for the first time in Guangdong.

The First Use of Braille Test Paper in Guangdong

Yesterday morning, Guangdong Education Examinations Institute held a press conference. At the meeting, Fan Shaobin, vice president of the Provincial Education Examinations Institute, introduced that the 7th was the first day of the college entrance examination in 2019. The morning Chinese exam was a beautiful day. When entering the exam, the weather in the province was good and the admission order was very good. No candidate was late because of the rain.

This year, the province has set up 470 test sites and 23,800 examination rooms in 21 cities. On the first day of the examination, the leaders of the party committees and governments of all localities and cities went to the college entrance examination command center to check the college entrance examination. In 2019, the number of applicants for the general college entrance examination in Guangdong Province was 768,000, an increase over last year. The number of students who participated in the college entrance examination on June 7 and 8 was 685,000, an increase of 20,000 over last year.

Fan Shaobin introduced that this year, Guangdong has strengthened security and confidentiality work and strengthened the implementation of responsibilities. Public security, network information, meteorology and other departments work together to escort candidates. Among them, Zhongshan City pioneered the service of sending lost documents with drones, and used drones to send certificates for candidates who forgot to bring admission tickets. Dongguan has adopted the remote verification service of ID cards and opened a green channel. 420 "love through trains" were opened in Heyuan city, and candidates were picked up and dropped off for free. Maoming candidates can get a red ribbon for free with the admission ticket, which is tied on the rearview mirror of a car or motorcycle. During the college entrance examination, the general public will be polite to the candidates who wear the red ribbon and escort the college entrance examination.

At various test sites, printing admission tickets and handling temporary id card for candidates on site have also warmed the hearts of many candidates. According to reports, on the morning of the first day of the college entrance examination, the examination institute has received the information that two candidates lost their ID cards, and both of them handled the documents in time through the temporary id card handling office of the public security bureau, and entered the venue smoothly. At the same time, many vehicles were escorted by the traffic police and arrived at the examination room smoothly.

It is worth noting that another candidate in Jieyang, Guangdong Province used Braille papers this year. It is reported that this is the first time that Guangdong has used Braille test papers. To this end, before the exam, Guangdong specially sent people to Beijing to collect the papers. This morning, the candidate successfully opened the exam. According to reports, this special test paper, like other candidates, is only made in Braille.

In addition, Guangdong has provided more convenience for disabled candidates this year. On the morning of the first day of college entrance examination, 99 spare test rooms were opened in Guangdong to arrange examinations for disabled candidates and special candidates. According to reports, there are 13 colleges and universities in China that recruit students with visual and hearing disabilities. At present, these 13 colleges and universities have pre-enrolled 147 candidates.

Multi-departments make every effort to escort the exam

The reporter learned from the Guangzhou Admissions Office that there were 79,168 candidates in Guangzhou this year, 58,704 candidates took this cultural course exam, 55 test sites were set up, and 2,087 examination rooms were opened. This year’s college entrance examination coincides with the Dragon Boat Festival holiday. The departments of public security, transportation, fire protection, confidentiality, industrial letter, environment, meteorology, power supply and so on fully escort the examination, and send personnel to be on duty at the municipal education examination command and monitoring center.

On the first day of the examination, the weather in Guangzhou was generally fine, the road traffic was generally smooth, and the candidates went to the examination smoothly. No candidates were unable to go to the examination due to traffic jams. The surrounding environment of each examination center was quiet and orderly, the examination equipment was in normal operation, the examination papers were transported normally, the examination style and discipline were good, and the examination in the city was smooth and smooth.

Yesterday morning at 9: 00, Zhang Shuofu, secretary of the Municipal Party Committee, visited the Education Examination Command and Monitoring Center and listened to the report of Director Fan Qun of the Municipal Education Bureau on the opening of the first day of the college entrance examination. He also made an online tour of the education examination command centers and test sites in various districts through the high-definition video conference system and the examination room monitoring system, and sent letters of condolences to the recruitment departments at all levels and the examination workers in the city.

Zhang Shuofu fully affirmed a great deal of work done by the member units of the joint meeting of all districts and bureaus and the recruitment departments at all levels in the early stage, and pointed out that Guangzhou is an inclusive and open city, with a large number of people from all over the country working and living in Guangzhou. The enrollment examination work should fully reflect Guangzhou’s inclusiveness and openness. I hope that all the examiners will "Do not forget your initiative mind, keep in mind the mission", do all the work in detail with more powerful measures and more excellent means, and serve the candidates with their hearts.

According to the forecast of the meteorological department, the highest temperature in Guangzhou will approach or reach 35℃ today and tomorrow, and there may be thunderstorms in some areas. Candidates are requested to prepare for heatstroke prevention, take rain gear when traveling, arrange the trip to the exam reasonably, and pay attention to traffic safety on the way. In case of emergency, you can call "110" or directly ask the on-site police for help.

safeguard

There were no candidates who missed the exam due to traffic problems in Guangzhou traffic police.

The reporter learned from the Guangzhou Traffic Police Detachment Command Center that during the college entrance examination, the Guangzhou traffic police started the first-class service, and the whole police went on the road, giving full play to the intelligent new traffic control function, giving early warning and rapid response to road traffic congestion, realizing unblocking and ensuring smoothness, and fully ensuring road safety and order.

Among them, in response to the candidates’ help, through the command linkage mechanism in time, the nearby police force was quickly deployed to safely escort the candidates to the destination examination room. At the same time, meteorological, water, emergency, transportation and other departments stationed in the smart traffic command center, establish and improve the emergency linkage command mechanism, and minimize the impact of possible bad weather on the college entrance examination.

During the college entrance examination, 55 test sites in the city arranged to formulate a "one-point-one plan", strictly controlled the inner area of the examination room, and strengthened the guidance outside the examination room to ensure smooth traffic. Among them, 30 test sites in the city will implement temporary traffic control 30 minutes before the test, prohibiting all motor vehicles from entering the controlled sections (residents who drive motorcycles in and out of the controlled sections outside the motorcycle ban can be allowed to turn off the engine).

Police officer Liu of Guangzhou Traffic Police Command Center introduced that on the first day of the college entrance examination, Guangzhou traffic police received two cases of asking for help (one teacher and one candidate), which occurred in Yuexiu District and Liwan District respectively. The police found the helper in time and successfully delivered it to the examination room with a police motorcycle.

At 7: 55 in the morning, the traffic police in Guangzhou received a teacher’s help. Because of the wrong examination room, he had to rush from Tieyi Middle School to the test center in No.7 Middle School. The police used a police motorcycle to deliver it to the Seventh Test Center in just 2 minutes. At 8: 36 in the morning, a candidate who went to the wrong examination room in the No.1 middle school of the city was also successfully sent to the provincial examination room.

According to the traffic police in Guangzhou, on the first day of the college entrance examination, there were 2,280 police officers in Guangzhou, including 420 in the Yangcheng Tieqi Guard Examination Team. According to the data analysis, from 7: 00 to 9: 00 on the same day, there were 167 traffic alarms in the city, down 58% compared with last year’s college entrance examination, only 8 cases of congestion alarms, down 90% year-on-year, and the congestion index of Gaode ranked 100 in the country. There were no candidates who missed the test due to traffic problems, and 230 pieces of traffic information were released through various information platforms.

Guangzhou traffic police reminded that during the college entrance examination this year, it is the "dragon boat water" season in Guangdong. Parents and candidates should pay attention to preparing umbrellas, raincoats and other "rain gear" to go out, and at the same time make full plans and plan the plan for rushing to the exam in advance.

Cctv news(News Network): In combination with local characteristics, Longyan, Fujian Province has increased the cultivation of new formats such as online consumption and platform economy, raised the consumption level, and stimulated the new vitality of the old district economy.

At present, the live broadcast rooms of various agricultural products in Longyan are very lively. Peanuts, dried sweet potatoes and passion fruits have become the protagonists promoted by fruit farmers. Here, mobile phones have become "new farm tools" and live broadcasts have become new farm work.

Li Qiusong, the inheritor of Fujian time-honored Longyan’s "Shan Erzai" skillWe have many good products and time-honored brands in Longyan, which used to be known only by local people. Now, through e-commerce, we do live broadcast and bring goods, and promote these good things to the whole country. The sales volume has gone up at once, and sometimes it even exceeds the supply.

Longyan is rich in high-quality agricultural products with good quality and low price, but in the past, the channels were single and the sales were not smooth. In recent years, Longyan has adapted to local conditions, guided farmers and enterprises to change the traditional sales model, popularized speed-up network broadband, and trained e-commerce skilled personnel. In 2015, rural e-commerce in Longyan developed rapidly, covering all counties, townships and villages in the city. Today, Longyan has built 12 e-commerce industrial parks, with more than 36,000 e-commerce enterprises and nearly 40,000 direct employees. In the first half of this year, Longyan’s online retail sales reached 7.36 billion yuan, an increase of 71.7%.

Cctv news(Reporter Sai Xinyan, Li Shanshan) "What you see is the special agricultural product of Zhangchangfeng Village: three red flags and four jars of sauce, no pesticides and no fertilizers. Flour is rich in micro-nutrients, and the taste is absolutely good. "The weight of a single peach is 0.5-0.8, and the sugar content is 15%-20%."

Zhang Weiting, deputy researcher of the Supervision Office of the State Bureau for Letters and Calls, and the "first secretary" of Zhang Changfeng Village, Haixing County, Cangzhou City, Hebei Province, impressed the introduction of agricultural products as well as the tour guide’s words.

Now Zhang Weiting is full of confidence, saying that "the name Changfeng represents the hope of the villagers, and I want to lead everyone to achieve a bumper harvest". In 2018, when I first came to Zhangchangfeng Village to help the poor, Zhang Yuting was not so chic. There are 438 households in the village and 125 poor households with established cards; The village is all saline-alkali land, and the yield of wheat per mu is low, so it depends on the weather to eat. But even so, Secretary Zhang led the villagers out of a "Changfeng" road.

"Tukela" becomes "golden pimple"

Zhang Weiting never helped the poor. Before coming to Zhang Changfeng village, she imagined that this small coastal village was a "paradise" facing the sea and blooming in spring. However, after coming here, I learned that the collective industry in the village is almost zero, and "the electricity bill can’t be paid soon." Without industry, the villagers can only go out to work and live a tight life. Once they are sick and hospitalized, they can’t get out 10,000 yuan or 20,000 yuan of life-saving money … …

In the eyes of the villagers, it is strange that Zhang Changfeng is not poor: "After hard work for half a year, an acre of wheat received 300 kilograms, and they all sold for more than 300 yuan. If you want to be rich, unless ‘ Tukela ’ Become ‘ Golden pimple ’ ！”

Zhang Weiting is trying to challenge this "impossible". The first thing she did when she came here was to transform the old primary school site that had been idle for many years at the entrance of the village into a village cultural and sports center. She believes that "finding a way to seek development in the village and letting the labor force return to work in the village" is the direction for the villagers to get rich, so that everyone should "form industrial ideas and believe that we can do business ourselves and have ambition".

However, where is the way?

On a visit to the villagers, Zhang Weiting took a bite of the steamed bread stuffed by the villagers. "Take a bite, it smells good! I found the taste of childhood in an instant. "When I asked, I knew that the dry land wheat" Dahongwang ",which is widely planted in the village, grew in saline-alkali land without pesticides, fertilizers and watering. Although the yield was low, it tasted good. Zhang Weiting seems to have discovered the "New World". She gave this steamed bread with "childhood flavor" to friends in Beijing to taste, and also found relevant laboratories to test it. Soon, experts came to the conclusion that "the growth cycle of hard wheat is long, and the content of potassium and plant protein is higher". Zhang Weiting was ecstatic, and the gluten of steamed bread is scientific.　

　Zhang Weiting (right) works as a farmer in a villager’s home.

"This is a good thing in a big city." After a family visit and a family talk, Zhang Weiting also found that there are still many "treasures" in the village: Chili sauce made by Dai Shufeng is loved by relatives and neighbors; The noodles pressed by Ma Yujuan are very strong without salt; Zhang Changfeng’s pasta is famous in the local area, and every family will make delicious noodles and steamed buns … … If you sell these to the city people, are you still worried that the villagers will not be rich?

Therefore, Zhang Weiting led the villagers to study and improve varieties in many places, and invited experts from Beijing to give lectures, leading the villagers to do deep processing, and produced special agricultural products such as stone mill wheat flour and rye flour. Unexpectedly, the villagers don’t think so. In the eyes of the villagers, these are just the most common things at home. They don’t cooperate with the establishment of a unified sales channel and don’t trust this new "temporary secretary".

In the end, Zhang Weiting had to take risks to acquire at a price higher than the market price, and then look for sales channels from her side: she recommended it to colleagues and classmates in the WeChat group; I bought it myself and sent it to a friend far away; Boarded the stage of "Open the Door" and Chongqing Satellite TV with "Zhang Changfeng" products.

　"Cultivate ambitious and wise villagers"

Zhang Weiting devoted herself to the work in the village. After the market was opened, Zhang Weiting found that the villagers had no uniform standard for the processing and quality control process of characteristic agricultural products. Once packed hundreds of boxes of carrots, the villagers’ packing quality was uneven. Most of them felt "indifferent", but Zhang Weiting felt that this was not a small problem. "You can’t smash your signboard because of small details." She and a few villagers re-examined and loaded hundreds of boxes of carrots, and told the villagers with actions, "Be wise and learn how to walk every step." Later, Zhang Weiting described that day as "really tired and falling apart".

"Don’t look at being a lesbian, you don’t want to work hard." Liu Yusheng, former deputy director of Haixing County Bureau of Commerce, said jokingly.

In order to make the rural characteristic products of Zhangchangfeng Village into brands, Zhang Weiting put forward the slogan that "China is good in Haixing, and Haixing is good in Changfeng", applied for registration of the trademark of "Zhangchangfeng", opened a shop on the platform of Wechat business, and set up a column of "Secretary Mall" in the village WeChat WeChat official account to plug in the wings of the Internet for characteristic agricultural products.

Open the "Secretary Mall" column of "Resident Poverty Alleviation Cadres" WeChat in WeChat official account, and the sales of pasta in Zhangchangfeng Village firmly occupy the top three, followed by the Chili sauce on "Open the Door". In recent months, Dai Shufeng, who makes Chili sauce, has sold hundreds of bottles of Chili sauce, earning nearly ten thousand yuan.

In addition, Zhang Weiting is also committed to the development of orchard construction. "Before, the information in the village was relatively blocked, and there was no investment and no labor, so there was no development. Now I am here!" In 2019, the total investment was 2.4 million, and the peach project covering an area of more than 100 mu was successfully "uphill". On September 21st, when Peaches entered the supermarket in Cangzhou, Zhang Weiting happily sent several friends in succession.

Zhang Weiting said: "It is my goal to push these things to the whole country. “

　"No, it feels like I’m going to be red."

The "first secretary" will not only develop industry, but also play well in Internet marketing. Zhang Weiting said with a smile, "It’s because many customers have given me advice. Recently, they suggested that I make a short video".

Zhang Weiting has a WeChat group to share the special products in the village. People inside value the unique quality of Zhangchangfeng village specialty and often contribute sales. "People say this is called community operation".

Zhang Yuting said that now 123 poor households in Zhangchangfeng Village have successfully lifted out of poverty, and the other two households have not lifted out of poverty due to mental retardation and other reasons. After consultation by the "two committees" of the village, the bottom-line policy will be implemented for these two special families.

Today, the flour in Zhangchangfeng Village is still the same flour, but its value has risen from 2 yuan to 12 yuan per kilogram. The income of more than 40 poor households doubled that year. Members of the cooperative work in the processing workshop, and they get 60 yuan’s salary every day, with dividends at the end of the year. "I didn’t expect the ‘ Tukela ’ Really became ‘ Golden pimple ’ ！” This seaside village is also quietly moving towards the carefree village of "spring blossoms" in Secretary Zhang’s heart.

　　Recently, mycoplasma pneumoniae is prevalent in some areas, and the number of cases of mycoplasma pneumoniae infection in children in some hospitals has increased. What is mycoplasma pneumoniae infection? What symptoms should be vigilant? How to do a good job of prevention and control? In view of the hot spots of social concern, the reporter interviewed Xu Baoping, director of the Department of Respiratory Medicine of Beijing Children’s Hospital affiliated to Capital Medical University, Zhao Shunying, director of the Department of Respiratory Medicine of Beijing Children’s Hospital affiliated to Capital Medical University, and Zhang Haidi, a pediatrician of the First Affiliated Hospital of Guangzhou Medical University.

　　Q: What is mycoplasma pneumoniae infection?

　　A: Mycoplasma pneumoniae is a pathogenic microorganism between bacteria and viruses, with a diameter of 2 microns to 5 microns. It is a prokaryotic pathogenic microorganism and lacks cell walls. Mycoplasma pneumoniae is mainly transmitted by droplets and direct contact, and the incubation period is 1 to 3 weeks.

　　Mycoplasma pneumoniae infection often occurs in any season, and it is prevalent in autumn and winter in the north, but in summer and autumn in the south. It occurs periodically every 3 to 7 years, and the epidemic time can be as long as 1 year. Mycoplasma pneumoniae infection is a common respiratory infectious disease in children in China, which is more common in children aged 5 and above, but children under 5 can also get sick.

　　Q: What are the manifestations of mycoplasma pneumoniae infection? What symptoms should be vigilant?

　　A: The clinical manifestations of children with mycoplasma pneumoniae infection are quite different: mild patients may not get sick, or only show upper respiratory tract infection; Severe cases can cause pneumonia, lung consolidation, pleural effusion and so on.

　　The main clinical manifestations of the disease are fever and cough, which may be accompanied by headache, runny nose, sore throat, earache, etc. Persistent high fever suggests that the condition may be serious. Some children have wheezing, especially infants.

　　Parents should take their children to see a doctor as soon as possible if they find that they have a severe cough and high fever. If the child has symptoms of choking and breathlessness, parents can pat his back hard, clean the airway and then go to the hospital as soon as possible.

　　Q: The symptoms of mycoplasma pneumoniae infection are easily confused with influenza and other diseases. How to distinguish them?

　　A: There are many methods to diagnose mycoplasma pneumoniae infection, such as serum antibody detection and nucleic acid detection. Whether it is mycoplasma pneumonia or not requires a doctor to comprehensively judge according to the child’s medical history, symptoms and signs, combined with relevant routine laboratory tests.

　　In addition to combining clinical and imaging manifestations, etiology and serological examination, parents can also observe the cough of their children. Mycoplasma pneumoniae infection usually has paroxysmal and serial coughs, with dry cough in the early stage and severe cough, which even affects eating and sleeping.

　　Q: How to prevent it?

　　A: Mycoplasma pneumoniae is inherently resistant to antimicrobial agents (such as penicillin and cephalosporins) acting on cell walls. At present, the first-line drugs are mainly macrolide antibiotics, and the commonly used drugs include azithromycin, erythromycin and clarithromycin. Children with macrolide resistance may need to use other antibiotics.

　　Antibiotics are prescription drugs and must be used under the guidance of a doctor. Children with refractory mycoplasma infection and severe mycoplasma infection need comprehensive treatment, such as glucocorticoid and bronchoscopy intervention. In February this year, the National Health and Wellness Commission issued the Guidelines for Diagnosis and Treatment of Mycoplasma Pneumonia in Children (2023 Edition), aiming at further improving the standardized level of diagnosis and treatment. The key is to identify and see a doctor in time, and the best treatment window period is within 5 days to 10 days after fever.

　　To prevent mycoplasma pneumoniae infection, we should develop good personal hygiene habits, such as keeping social distance, hand hygiene, frequent ventilation, etc., and wear masks when necessary. Indoor ventilation in autumn and winter should also pay attention to keep warm.

　　Q: Will mycoplasma pneumonia cause "white lung"?

　　A: This kind of pneumonia may bring mucus plugs to block the bronchi, which may lead to "atelectasis", that is, the decrease of lung gas content, resulting in "white lung" in imaging. But this is two concepts with the "white lung" of diffuse lesions in both lungs.

　　By tapping the back to expel phlegm, eliminating phlegm with drugs, bronchoscopy and other means, the child can be cured in a short time, and basically will not cause life-threatening. Most children with mycoplasma pneumoniae infection have a good prognosis. Children with severe and refractory mycoplasma pneumoniae infection may leave lung structure or function damage, which requires long-term follow-up. (Reporter Dong Ruifeng, Gu Tiancheng)
