How to pay three insurances and one gold? What are the rules for the payment ratio?

Three insurances and one fund include endowment insurance, medical insurance, unemployment insurance and housing accumulation fund, which are closely related to people’s lives, life security after retirement, reimbursement of medical expenses and satisfaction of housing demand. The following will introduce in detail the payment method and payment ratio of three insurances and one gold.

There are two main ways to pay three insurances and one gold: unit payment and individual payment. For on-the-job employees, three insurances and one gold are usually withheld and remitted by their units. Before the monthly salary is paid, the unit will deduct the personal contribution from the employee’s salary according to the regulations, and at the same time, the unit will also bear the corresponding contribution share and pay the money to the relevant departments in a unified manner. Taking employees of enterprises as an example, enterprises will transfer the three insurances and one gold fees payable by employees and enterprises to the accounts designated by social security agencies and housing provident fund management centers at a fixed time every month by means of bank transfer.

Flexible employees without fixed units, such as individual industrial and commercial households and freelancers, can also pay three insurances and one gold by themselves. They need to go to the local social security agency and the housing provident fund management center to apply for insurance and open an account. When handling, you need to bring your ID card, household registration book and other relevant information, fill in the application form, and choose the payment grade that suits you. Payment methods can be selected from bank withholding and online payment. For example, in some areas, it is convenient and fast to allow flexible employees to pay fees through mobile APP.

Regarding the proportion of payment, there are certain differences in different regions. The following are the approximate proportions in general:

Insurance/provident fund Unit contribution ratio Individual contribution ratio endowment insurance Generally 16%-20% 8% medical insurance 6% – 10% About 2% unemployment insurance 0.5% – 2% 0.2% – 1% housing accumulation fund 5% – 12% 5% – 12%

For example, in a certain area, the pension insurance unit pays 16% and the individual pays 8%; Medical insurance units pay 8% and individuals pay 2%; Unemployment insurance units pay 0.7% and individuals pay 0.3%; The proportion of housing provident fund units and individuals is 8%. Assuming that the employee’s monthly salary is 5,000 yuan, then the employee pays 400 yuan (5,000× 8%) and 800 yuan (5,000× 16%) for the monthly pension insurance; Medical insurance individuals pay 100 yuan (5000×2%) and units pay 400 yuan (5000× 8%); Unemployment insurance individuals pay 15 yuan (5000×0.3%) and units pay 35 yuan (5000 × 0.7%); 400 yuan (5000×8%) shall be paid by individuals and units for housing provident fund.

It should be noted that all localities will adjust the payment ratio according to local economic development level, average social wage and other factors. Therefore, when paying three insurances and one gold, it is suggested to pay attention to the changes of local policies in time, or call the local social security hotline 12333 and the housing provident fund hotline 12329 for consultation to ensure accurate payment.

  Hebi, Zhongxin. com, August 1 ST: Flood-fighting volunteers use their bodies to block piping. Doctors warn not to go into the water again.

  Zhongxin. com reporter Lu Yuguo

  Wang Haoming, who has volunteered for flood fighting and rescue work in Henan for five days, can’t go to Xunxian County to fight floods again.

  From July 27th to 31st, Wang Haoming from Heyang County, Weinan, Shaanxi Province participated in flood fighting and rescue in Weihui City, Xinxiang, Henan Province and Jun County, Hebi, respectively.

  Wang Haoming and other volunteers blocked the piping with their knees against sandbags. Photo courtesy of respondents

  On the evening of July 30, he led several volunteers to block the piping with their bodies, and cooperated with the officers and men of the armed police to successfully save the dam of Xichen Village in Xun County to ensure that the Xicheng District west of Weihe River in Xun County was not flooded.

  Because his feet were soaked in the flood for a long time in the past few days, on the evening of July 31, he was sent to the hospital because his feet were cracked, swollen and painful. The doctor warned him not to go into the water again in the near future.

  Wang Haoming, 30 years old, previously worked in Action body double. On July 23rd, when he was filming in Xi ‘an, Shaanxi Province, he learned that there was a rainstorm in Henan Province, so he decided to go to Xinxiang, Henan Province, which was seriously affected, to participate in flood fighting and rescue.

  Wang Haoming’s feet were slightly ulcerated due to long soaking time. Photo courtesy of respondents

  "On the 25th and 26th, there were no trains to Henan for two consecutive days." On July 27th, Wang Haoming first took a bus to Zhengzhou East, and then transferred to Xinxiang.

  Arriving at the edge of Weihui city at 12 o’clock, Wang Haoming took the initiative to find a job: standing in waist-deep flood water to help transfer trapped people. "If you are young, help them out; If you are older, just carry them out. "

  On the same day, Wang Haoming waded for 11 hours. The next day, local volunteers in Xinxiang drove him to Xunxian County, Hebi City, and went directly to Fuzhuang Dike to participate in the patrol of Dike and sandbag filling.

  On the morning of July 29th, Wang Haoming went to Wangzhuang to help transfer villagers. On the morning of 30th, he went to Fuzhuangdi, and on the afternoon of 30th, he went to Xichen Village. "I will run where people are most needed."

  Xichen Village Dam is a part of Fuzhuang Dam, which is the last line of defense to protect the Xicheng District west of Weihe River in Xun County. At 19 o’clock on July 30, piping occurred in the dam of Xichen Village.

  Wang Haoming, who was packing sandbags nearby, found the piping and jumped down decisively to explore the situation. "I looked at it with a flashlight, mainly because the bottom of the big sandbag was hollowed out, so I quickly used a shovel to smash the soil on both sides, so that the sandbag above could sink."

  In order to deal with piping as soon as possible, Wang Haoming shouted to others to throw sandbags quickly, while holding the sandbags with his knees to prevent them from being washed away by piping rapids. Several other volunteers followed suit.

  At the critical moment, the officers and men of the armed police who were carrying out the dike-fixing task nearby arrived quickly and immediately took over the task of blocking piping.

  "I counted, at least a dozen armed police officers and men held sandbags with their knees." Wang Hao said that his task was temporarily changed to cooperate with the officers and men of the armed police to widen and reinforce the dam. At 0: 30 the next day, the danger of piping was finally eliminated.

  Two hours ago, residents of Xicheng District, Weihe River in Xun County were urgently transferred. When the news came, many residents’ hanging experiences were put down.

  On July 31st, it was another busy day. That night, he was preparing to eat when he suddenly felt pain in his feet and it became more and more serious. "It hurts like a needle, which is particularly uncomfortable."

  When local volunteers sent Wang Haoming to Xunxian Chinese Medicine Hospital, his feet were swollen and there were some small cracks.

  "This is mainly because your feet have been in the water for too long, and the sediment has been ground badly. Note that you must not go into the water again in the near future, otherwise it will be troublesome to cause infection. " The doctor warned Wang Haoming.

  At the end of the interview, Wang Haoming said goodbye to the reporter of Zhongxin.com with an apology. "I am afraid that there will be no chance to participate in the follow-up rescue work. I hope that Jixian will win the flood control as soon as possible." (End)

From soil erosion area to green "cornucopia" —— Notes on soil erosion control in the upper and middle reaches of the Yangtze River

  Xinhua News Agency, Beijing, December 25thTitle: From soil erosion area to green "cornucopia" — — Soil erosion control in the upper and middle reaches of the Yangtze River

  Xinhua News Agency reporter Liu Shiping

  The Yangtze River Water Resources Commission of the Ministry of Water Resources recently issued the Announcement on Soil and Water Conservation in the Yangtze River Basin (2020). The monitoring results show that in 2020, the area of soil erosion in the Yangtze River basin will be 337,000 square kilometers. This is nearly 200,000 square kilometers less than the 531,000 square kilometers of soil erosion in the late 1990s.

  The reporter learned that soil erosion and its control in the Yangtze River basin are mainly concentrated in the upper and middle reaches. After treatment, the soil erosion area has not only been effectively curbed, but also turned into a green "cornucopia", becoming a green mountain and a Jinshan Yinshan.

  Sichuan: the soil erosion area has become a "green and rich beauty" ecological area

  Naxi District of Luzhou City is located on the bank of the Yangtze River, which is an important ecological barrier in the upper reaches of the Yangtze River. "In the past, the Qingxi River was like a stinking ditch, and the soil erosion in the Qingxi River basin was serious." Jiang Qiwu, director of the Naxi District Water Affairs Bureau, said that in recent years, the combination of governance and protection of the ecological environment has improved the water ecology and water environment.

  The water environment has been improved after the regulation of Qingxi River small watershed in Naxi District of Luzhou City.

  Changing from "stinking ditch" into Qingshui River and Huimin River is the effort of "seeing the big from the small" in Naxi District: "Small investment" to improve the "big environment", taking 30 million yuan of national special funds for soil and water conservation as a pry point, integrating agricultural funds and inciting social funds of 720 million yuan, realizing the improvement of water quality into the river from inferior V to III, and reducing soil loss by 75,000 tons every year; The "small watershed" has built a "great livelihood", the environment has improved, and tourism has started. At the same time, the implementation of watershed management land transfer and small-scale water storage projects has driven the per capita disposable income of farmers to increase substantially.

  Jingyang District of Deyang City, taking the management of Huaixiang Valley small watershed as a breakthrough, through the comprehensive management of landscape Lintian Road Village, combined soil erosion control with the development of rural industry and the improvement of human settlement environment, drew a picture of Jingyang where people and water are in harmony, and successfully established the "National Soil and Water Conservation Demonstration Project" in December 2021.

  A glimpse of Gaohuai Village after harnessing the small watershed of Huaixiang Valley in Jingyang District of Deyang City.

  "All parts of Sichuan regard the prevention and control of soil erosion as the first move in the construction of ecological civilization, actively carry out small watershed management, implement key projects such as sloping farmland management, improve the ecological environment, and at the same time promote regional economic development and help rural revitalization." Gao Wei, director of the Water and Soil Conservation Division of the Sichuan Provincial Water Resources Department, said.

  Statistics show that during the "Thirteenth Five-Year Plan" period, the cumulative area of soil erosion control in Sichuan Province was 24,600 square kilometers, and soil erosion in the areas with the most serious soil erosion, such as Jinsha River Basin, Minjiang River Basin and Jialing River Basin, was continuously improved.

  Jiangxi: Red soil erosion area becomes green "cornucopia"

  Walking into the Garden Village of Shangyou County, Ganzhou City, the village is beautiful and clean. Before 2013, it was still a serious soil erosion area.

  What has changed the landscape here is the development of eco-clean small watershed construction. The Garden Village has explored the ways of "three simultaneous treatments" for mountain management, water control and pollution control, mountain management and water conservation, river dredging and water management, industrial water conservation, ecological water purification, and "five-water co-construction" for everyone in love the water. While managing mountains and rivers, Shangyou County was successfully awarded "National Model County for Soil and Water Conservation" in December 2021.

  A glimpse of Garden Village in Shangyou County, Ganzhou City.

  In the early 1980s, the area of soil erosion in Ganzhou accounted for 37% of the city’s mountainous area. After more than 30 years of comprehensive control, the area of soil erosion has decreased from 11,187 square kilometers in 1980 to 6,949 square kilometers in 2020, and ecological industries such as navel orange and leisure tourism in southern Jiangxi have flourished.

  Changshui Village, Wuning County, Jiujiang City, in the north of Jiangxi Province, has achieved 95.2% soil erosion control and 96% forest and grass coverage through the simultaneous implementation of "mountain management, water management and pollution control" measures. In December 2021, the "National Demonstration Project of Soil and Water Conservation" was successfully established.

  Baoshan Village, De ‘an County, Jiujiang City, relied on antimony resources to develop the quarrying economy in the early 1980s. However, the industry is booming, but the environment is deteriorating.

  Since 2010, Baoshan Village has closed factories and mines one after another to restore the mine ecology. Villagers have planted cash forest crops such as camellia oleifera and tea on barren hills, making them put on "green clothes" again, and the days of villagers who eat ecological rice are booming again.

  According to the dynamic monitoring results of the Ministry of Water Resources in 2020, the area of soil erosion in Jiangxi Province has decreased from 46,200 square kilometers at the worst in the late 1980s to 23,600 square kilometers in 2020, and the proportion of soil erosion in the whole province’s land area has decreased from 27.65% to 14.14%.

  "The comprehensive management of soil erosion in Jiangxi Province has effectively promoted ecological protection and rural revitalization." Hu Jianmin, director of the Water and Soil Conservation Department of Jiangxi Provincial Water Resources Department, said.

  Yangtze river basin: comprehensive control of soil erosion continues to advance

  Soil erosion in the Yangtze River basin is caused by complex geology and geomorphology, abundant rainfall and unreasonable human production activities, with a large amount and various types, mainly in the upper and middle reaches of the Yangtze River.

  "After years of comprehensive management of soil erosion in small watersheds, the trend of soil erosion in the Yangtze River basin has undergone a historic turning point from increasing to decreasing." Zhang Guangfu, director of the Water and Soil Conservation Bureau of the Yangtze River Water Resources Commission of the Ministry of Water Resources, said.

  Since the 18th National Congress of the Communist Party of China, the Yangtze River Basin has implemented key water and soil conservation projects, comprehensive soil and water loss control on sloping farmland, clean small watershed construction, rocky desertification control, returning farmland to forests and grasslands, high-standard farmland construction, comprehensive mine improvement and other water and soil conservation ecological construction projects, and the Yangtze River Basin has achieved a double decline in soil and water loss area and intensity grade.

  The monitoring results show that the forest coverage rate in the upper reaches of the Yangtze River has reached 47.8% in 2020. The coverage rate of forest and grass vegetation in the Jialing River, the middle and lower reaches of Tuojiang River and the Three Gorges reservoir area in the Yangtze River basin has increased by about 30%, and the area of barren hills and slopes has decreased by 70%.

  Ma Jianhua, director of the Yangtze River Water Conservancy Committee of the Ministry of Water Resources, said that there are still 220,000 square kilometers of soil erosion areas in the upper reaches of the Yangtze River that need to be treated urgently. With the economic and social development, it is urgent for soil and water conservation to meet the needs of high-quality development. The phenomenon of extensive soil erosion and serious local problems also exists in the middle reaches of the Yangtze River, and soil and water conservation has a long way to go.

  It is understood that during the "Tenth Five-Year Plan" period, the Yangtze River Basin will build a complete soil erosion prevention and control system by promoting coordinated management, comprehensive management, systematic management and source management, and vigorously promote the soil and water conservation work in the upper and middle reaches of the Yangtze River to a new level.

Engine Technical Tour (13) Analysis of C4LEC8 Engine

  【Pacific Auto Network Technology Channel】 1.6L was once the first choice for family cars because of its sufficient power and relatively low fuel consumption. However, with the improvement of consumption level, the size of family cars is getting bigger and bigger, and the power of 1.6L displacement is just enough. If the vehicle is fully loaded, it will be a bit of a small horse-drawn cart, and the driving pleasure has long been gone. 2.0L displacement power is sufficient, but high fuel consumption is inevitable. To make a compromise, 1.8L displacement power and fuel economy are the most suitable. I also saw this opportunity, and developed a brand-new 1.8L engine in five years. This engine code is EC8, which is currently mounted on Dongfeng models. This issue will bring you the technical analysis of Dongfeng EC8 1.8L CVVT engine.

● Fuel consumption of ●1.6L and power of 2.0L displacement.

  EC8 is a brand-new engine launched by PSA for China market. EC8 engine claims to have the fuel consumption of 1.6L displacement engine and the power of 2.0L displacement engine, and its performance level is in the advanced position of naturally aspirated engine.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  It can be seen from the EC8 engine diagram that about 90% of the peak torque has erupted in the engine at 1500 rpm, and the torque curve is relatively gentle and lasts until 6000 rpm.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  It has good dynamic performance in the daily use speed range, and reaches the peak torque at the earliest in the same class. The most intuitive feeling is that when the start accelerates, the low speed is very fast. The output that can be obtained in the 1500-2000 shift range that Chinese people are used to can be described as a little bit of power and a steady stream.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  With the power of the 2.0L displacement engine, where does the fuel consumption of the 1.6L displacement engine come from? Of course, it depends on technology. For example, EC8 engine adopts cylinder honing technology, micro-grooved tile technology, variable displacement pump, DLC coated hydraulic tappet, intelligent timing gear damping technology, belt and so on. Listen to me together.

  Flat-top honing can shorten the early running-in process and improve the fuel consumption and engine oil consumption during the running-in period. It can form a multi-reticulated small platform, which can greatly improve the lubrication condition of the friction pair, prolong the service life of the cylinder hole and piston ring friction pair and prolong the time. This technology is also widely called "pre-running-in" by experts, which can minimize the running-in wear of users when driving new cars, improve the reliability of vehicles to a greater extent, and save users’ maintenance costs.

  In addition, crankshaft bearing has also adopted the micro-grooved tile technology. Micron grooves are machined on the surface of bearing bush by special machining method. The application of micro-grooved tile technology improves the compliance of bearing bush and accelerates the early running-in between bearing bush and crankshaft. Improve the fluidity of lubricating oil in the minimum oil film thickness area and enhance the cooling effect of engine bearing bush; The distribution area of lubricating oil film along the width direction of bearing bush is larger, which can increase the thickness of oil film in most high-pressure working areas and prevent the bearing bush from sticking.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  The application benefits of micro-grooved tile technology are to reduce the mechanical loss of moving parts and improve the engine efficiency; Improve the reliability of moving parts and prolong the service life.

  The combination of cylinder flat-top honing technology and crankshaft bearing micro-groove tile technology reduces the power consumption in crankshaft operation engineering. The inspection in the assembly workshop shows that the friction of crankshaft rotation needs to consume 3.6N·m engine torque.

● Variable pump

  There is also an oil pump directly connected with, and the operation of the oil pump also consumes a part. According to relevant foreign research reports, the use of variable displacement oil pump can generally reduce the fuel consumption of the engine by 1%-2%. To reduce the power consumption of the oil pump, it is necessary to match the oil supply of the oil pump with the actual oil demand of the engine. The use of variable displacement oil pump can meet this requirement.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  The variable displacement oil pump used in EC8 engine is provided by Magna Powertrain (Changzhou) Co., Ltd.. EC8 oil pump is a variable displacement vane pump, which can be mainly divided into sliding variable vane pump and swinging variable vane pump. The variable principle of the two types of vane pumps is basically the same: the eccentricity between the outer adjusting ring and the rotor is changed by sliding or swinging, and then the displacement of the vane pump is changed.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  When the feedback oil pressure reaches the variable set value, it is compressed, and the outer adjusting ring slides or swings, so that the eccentricity between the inner ring and the outer ring of the blade is reduced, and the variation of the oil pressure cavity formed between the blade and the inner and outer rings is also reduced correspondingly during the operation of the oil pump, thus reducing the oil pump flow; When the feedback oil pressure decreases, the spring gradually returns to reset the adjusting ring.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  Main oil passage pressure feedback pressure control mode, which takes the feedback pressure point as the main evaluation point of engine pressure, has small pressure fluctuation and is close to the main lubricating parts, and can accurately reflect the engine oil pressure demand. By adopting main oil passage pressure feedback, the pressure control is more accurate and close to the engine demand, and the oil pump efficiency is higher.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  The variable displacement pump keeps the pressure of the main oil passage of the engine at medium and high speed at a relatively constant value, which can meet the engine oil demand, reduce power consumption and play the role of energy saving and emission reduction. The variable displacement vane oil pump of EC8 engine is at the top level in China, with low power consumption and stable oil pressure control. Users can reduce engine power consumption and fuel consumption when driving a vehicle.

●DLC coated hydraulic tappet

  The working surface of EC8 hydraulic tappet is also coated with Diamond-like Carbon for short. The surface of DLC coating is black, which has comprehensive excellent properties such as stable quality, good adhesion with matrix, good wear resistance, low friction coefficient and good corrosion resistance.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  The hardness of DLC coating can reach 8000HV, the friction coefficient is as low as 0.05~0.2, and the coating thickness is 0.5-10μ M, the highest heat resistance reaches 800℃.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  After the tappet is coated, the surface friction coefficient is significantly reduced and the hardness is higher, which significantly improves the wear resistance of the tappet surface and greatly reduces the friction loss between the cam and the tappet surface. While reducing the working noise, it also reduces the power consumption of the engine, thus achieving the purpose of reducing fuel consumption and reducing the cost of car use.

● Intelligent timing gear damping technology

  Through the special formal gear profile design, a controlled and periodic phase interference is formed to eliminate the torsional vibration of camshaft and reduce the dynamic tension of belt.

●CVVT timing technology

  CVVT is a technology that changes the opening time of camshaft by electro-hydraulic control system, so as to control the required valve overlap angle. This is not a novel automobile technology. Now many engines have adopted this mature and reliable technology.

Engine Technology Tour (13) Analysis of Dongfeng Citroen EC8 Engine

  EC8 engine adopts the VVT technology of INA, which can adjust the intake valve timing and phase in a wide range of angles to ensure that the engine can meet the requirements of middle and low speed and high speed at the same time. The driving comfort, fuel economy and emission are obviously improved. CVVT technology can ensure the charging efficiency of the engine under different working conditions and improve the low-speed end torque by 5-10%. 5-8% high-speed power is increased, so that users can get better power output when starting at low speed, and high engine power is maintained at medium and high speed. The fuel economy can be improved by 1-3%, making the vehicle more fuel efficient. Under the limited NOx level, HC emission can be reduced by 25% at most, and the stability at idle speed is improved, and the driving comfort is better.

  Summary:Throughout the whole paper, EC8 engine should have many advanced engine technologies besides the original mature, stable and reliable technologies. The development time is relatively short, the cost is relatively low, and the existing market resources can also be used to some extent. The same is true from the user’s point of view. What users are most worried about is whether the performance is stable or not, and it is not easy to buy accessories when there is a fault, which just solves these problems. With five years’ unremitting efforts, the brand-new EC8 engine has been developed with "high efficiency, low consumption and high reliability" in consideration of power, fuel consumption, comfort and reliability. The slogan of the power of the 2.0L engine and the fuel consumption of the 1.6L displacement engine will never be groundless.

Adhere to "ecological priority and green development" in all localities and continue to write a new chapter in the concept of "two mountains"

  Beijing, August 14, 2005 According to the report of China Voice "National News Network" of the Central Radio and Television General Station, on August 15, 2005, when the then supreme leader of Zhejiang Provincial Party Committee visited Yucun, Anji County, Huzhou City, Zhejiang Province, he first proposed "Lucid waters and lush mountains are invaluable assets". Nowadays, the concept of "Lucid waters and lush mountains are invaluable assets" has become the consensus and action of the whole party and society, and has become an important part of the new development concept. Since the 18th National Congress of the Communist Party of China, under the guidance of the concept of "Lucid waters and lush mountains are invaluable assets", all localities have actively practiced the ecological civilization thought of the supreme leader, adhered to ecological priority and green development, made great efforts to solve outstanding environmental problems, strengthened the protection of ecosystems, and continued to write a new chapter in the concept of "two mountains" in continuous practice.

  In September 2013, when the Supreme Leader answered students’ questions at Nazarbayev University, he explained the concept of "Lucid waters and lush mountains are invaluable assets": "We want green mountains and green hills, but also Jinshan Yinshan. I would rather have green mountains and green hills than Jinshan Yinshan, and Lucid waters and lush mountains are invaluable assets. "

  The concept of "Lucid waters and lush mountains are invaluable assets" gives consideration to economy and ecology, development and protection, and provides important guidance for adhering to green development and building beautiful China in the new era.

  Do not exchange temporary economic growth at the expense of the environment, and do not take the old road of "pollution first, then treatment". In Xilin Gol League, Inner Mongolia, more than 60% of the area in the League has been designated as the red line of ecological protection, and no new mine development projects will be built on the grassland. By June 25th, 67 industrial and mining enterprises in six national nature reserves in Xilin Gol League had all closed down. Ma Weiguo, deputy director of the Natural Resources Bureau of Xilin Gol League, said: "According to ‘ If you are green, you will survive; if you are not green, you will retreat ’ It is required that by the end of 2023, all our production mines will meet the standards of green mines. "

  Since the 18th National Congress of the Communist Party of China, a number of systems, such as evaluation and assessment of ecological civilization construction objectives and accountability for ecological environmental damage, have been promulgated and implemented. The central eco-environmental protection inspector started the pilot project in 2015, and by 2018, it has achieved full coverage of routine inspectors in 31 provinces (autonomous regions and municipalities) and Xinjiang Production and Construction Corps, and the role of the inspector’s sword has been effectively played.

  At the same time, in view of the ecological and environmental problems accumulated in China’s rapid development over the years, ecological restoration has been placed in a more prominent position in various places. In order to protect the ecological environment of the Yangtze River, from January 1 this year, 332 nature reserves and aquatic germplasm conservation zone in the Yangtze River basin were completely banned from productive fishing. The main stream of the Yangtze River, important tributaries and large Tongjiang lakes will be temporarily banned for 10 years from 0: 00 on January 1, 2021 at the latest.

  As the province with the longest mileage flowing through the main stream of the Yangtze River, Hubei has set up a file for all the more than 26,000 fishermen who have retired in the province to ensure the implementation of the no-fishing measures. Since July 1st this year, the Yangtze River has been closed to fishing for ten years in Jingzhou City. Bie Shaobo, deputy secretary and deputy director of the Party Group of Jingzhou Agricultural and Rural Bureau, said: "The most important thing is to accurately set up files for these fishermen and transfer them to jobs for training, so that they can be reborn. We are determined to use the greatest strength and the most powerful measures to advance this work and achieve the goal we should achieve as soon as possible. "

  In the comprehensive experimental zone of marine ecological civilization of Long Island in Yantai, Shandong Province, the coastline ecology of Long Island has been gradually restored through measures such as vacating coastal aquaculture. At the same time, four state-level marine pastures and six provincial-level marine pastures will be built in Long Island, and the construction of marine pastures will create a "green water and green mountains" at sea, leading the marine fishery from the nearshore to the deep blue. Li Junjie, the full-time deputy secretary of the Working Committee of the Long Island Marine Ecological Civilization Comprehensive Experimental Zone, said: "People have to be compensated for their investment in these areas. In addition, we should consider their changing jobs. What ordinary people used to raise seedlings led to the tourism industry and the cultivation of offshore seafood. We must protect the fruits of our ecological restoration and let the people feel happy living in Long Island. "

  In recent years, Fuxin City, Liaoning Province, the first pilot city for economic transformation of resource-exhausted cities in China, has developed 12 theme racetracks of various types by using abandoned pits. The green development model of "ecological restoration+industry" makes the "urban scar" of Baili realize a gorgeous turn from black to green. From the end of 2018 to 2019, the newly-built Centennial International Circuit City has held six cross-country events and received more than 200,000 visitors. The bustling crowd has also brought a good life and new hope to the local people. Mr. Ma, a citizen, said: "The Gangzi Mountain in the past has now become an ecological park, with birds and flowers. The construction speed of the track city is particularly fast, and the surrounding facilities such as greening and roads are very good, as well as container hotels, which are fashionable and modern and more and more international. "

  Environment is people’s livelihood, green hills are beautiful, and blue sky is also happiness. Holding the green mountains and green hills, not only Jinshan Yinshan is harvested, but also the people’s hearts are full of sense of gain and happiness.

  In Chengdu, Sichuan, Tianfu Greenway, which has been built for more than 3,689 kilometers, has become the most inclusive livelihood project in the park city; In Hebi, Henan Province, the Qihe River scenic belt with a total length of about 6 kilometers has become a good place for citizens to relax; In Lanzhou, Gansu Province, the local government combined the Yellow River management with the improvement of people’s happiness index to create various landscape belts along the Yellow River. Chen Yifu, director of Lanzhou Natural Resources Bureau, said: "Increase public service facilities, make the Yellow River a happy river for the people, and build Lanzhou into a demonstration area for the high-quality development of the Yellow River and a pioneering area for ecological protection."

  In Zhongliao Village, a Li village in the north of Sanya, Hainan, the once unknown Zhongliao Village "Butterfly Change" is a well-known "star" village in Hainan. The villagers have a "tourist meal" at their doorstep and sing a happy song of the Liao people in the new era.

  At present, the national forest area has reached 220 million hectares, and the forest coverage rate is 22.96%. In the past 20 years, the new vegetation coverage area ranks first in the world. The number of cities with national air quality standards increased from 73 in 2015 to 157 in 2019. With the solid progress of ecological civilization construction, a beautiful new picture of China is slowly unfolding.

The Ministry of Education released the early warning information of the 2024 college entrance examination!

Click on the blue word above to pay attention to "vitality and harmony"

College entrance examination is a big test in the life of college students, which is related to the vital interests of candidates and has attracted much attention from the society. The college entrance examination in 2024 is approaching, and the majority of candidates are actively adjusting their status and preparing for the exam calmly and orderly. However, some lawless elements are driven by economic interests to spread false information about the exam, sell and create anxiety, and even commit fraud and induce candidates to cheat in the exam, which seriously disrupts the enrollment order of the exam. To this end, the Ministry of Education, in conjunction with relevant departments, has sorted out some typical cases that have appeared in recent years, and solemnly reminded the majority of candidates and parents that they must be vigilant, beware of being deceived, and do the integrity test. Let’s look at it together-

First, organizing cheating in the college entrance examination can’t escape the recovery of the French Open.

[Case] Before the college entrance examination in 2023, some criminals promised candidates through QQ group and other channels that they would pass the answers to the candidates during the college entrance examination. Candidates only need to bring in electronic devices and send back the questions. The Ministry of Education, the Ministry of Public Security and other relevant departments jointly conducted rapid investigation and successfully destroyed relevant criminal gangs before the exam.

【 Regulations 】 The Criminal Law of People’s Republic of China (PRC) clearly stipulates that it is illegal to "organize cheating" and "provide examination questions and answers to candidates" in the national examinations prescribed by law. The Interpretation of the Supreme People’s Court and the Supreme People’s Procuratorate on Several Issues Concerning the Application of Laws in Handling Criminal Cases, such as Cheating in Organizing Examinations, makes it clear that those who organize cheating in national education examinations, such as college entrance examinations and postgraduate entrance examinations, shall be deemed as "serious" acts, and shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and fined.

[Reminder] In recent years, local public security organs, together with the education departments, have continued to maintain a high-pressure and severe crackdown on all kinds of illegal and criminal activities involving exams. Remind the majority of candidates that they must enhance their legal awareness, know the law and abide by it, and don’t be confused for a while and regret it for life.

Second, "Gui Li" will eventually become "likui jy", and it is not feasible to challenge the law.

[Case] In the unified entrance examination of art and design major in colleges and universities in a province in 2020, two "exam-assisting" intermediaries found a college student to take the test for a candidate and were arrested by the police. Two cheaters were sentenced to three years and eight months in prison and three years and two months in prison respectively. Taking the test for college students was sentenced to five months’ criminal detention and suspended for one year.

【 Regulations 】 The Criminal Law of People’s Republic of China (PRC) clearly stipulates that it is illegal to "organize cheating" or "substitute others or let others take the exam instead of themselves" in the national examination prescribed by law.

[Reminder] In recent years, some new technical means have been gradually used in the management of national education examinations to prevent fraud such as taking exams. Although the results of college entrance examination are important, the quality of honesty is related to the development of a person’s life. Don’t believe in the temptation of criminals, and don’t be lucky enough to take the exam for others or let others take their place. Trying the law will eventually "eat the consequences".

Third, avoid the security belt "equipment", and the attempted cheating will ruin the future.

[Case] During the college entrance examination in 2022, a candidate avoided the entrance security check and illegally brought his mobile phone into the examination room. After the examination, he took a test paper and sent it to QQ group for an answer, which was unsuccessful, and was seized by the public security organs at the first time according to law. According to relevant regulations, candidates who violate the rules are dealt with seriously.

[Regulations] The college entrance examination is a national education examination prescribed by law. The Measures for Handling Violation of National Education Examination clearly stipulates that anyone who carries equipment with the function of sending or receiving information should be considered cheating in the examination, and the scores of all stages and subjects he signed up for the examination are invalid. The Education Law of the People’s Republic of China clearly stipulates that candidates who carry or use cheating equipment and materials in national education examinations, if the circumstances are serious, shall be ordered by the education administrative department to stop taking the relevant national education examinations for more than one year and less than three years; If it constitutes a violation of public security administration, it shall be punished by the public security organ according to law; If a crime is constituted, criminal responsibility shall be investigated according to law.

[Reminder] In recent years, the Ministry of Education, together with relevant departments, has deployed a special treatment for cheating on mobile phones in the college entrance examination, and resolutely prevented cheating on high-tech equipment such as mobile phones by strengthening the entrance clearance and invigilation clearance. During the examination, all candidates take the examination in the standardized examination room and under the whole video surveillance; After the exam, the video of the examination room will also be played back and reviewed. Candidates should consciously abide by the requirements of the rules of the examination room, obey the management of the examiners, refuse to carry illegal and prohibited items such as mobile phones, and abide by the examination discipline. Losing an exam is not important, but losing your life is not worth the loss.

Fourth, spending money to walk is not credible, and there is no "pie" with "trap"

[Case] Parents in a province received a short message from an unknown number, and then they received a message from their "daughter" who lived in the school, saying that they wanted to sign up for a training course offered by a well-known university. Parents are eager to love their daughters and have established contact with a "teacher Zhang" who is in charge of training matters. "Teacher Zhang" said that paying 300,000 yuan can "walk" to this prestigious school. Later, the "daughter" and "teacher Zhang" attacked each other and urged the payment for various reasons, defrauding a total of 180,000 yuan.

[Reminder] There is a strict workflow for college admissions. There is no such thing as "internal enrollment" and "paying for admission" in the process of college entrance examination. Candidates and parents should be highly alert to such deception under the guise of "spending money to buy university places" and "special channel admission". It is necessary to understand and confirm the examination enrollment policies and information from formal channels. False propaganda for some bad training institutions and criminals. Candidates and parents should not be credulous and deluded, so that they are deceived, causing property losses and delaying valuable review time.

Fifth, the college entrance examination volunteers have been tampered with, and information disclosure needs to be vigilant.

[Case] A candidate in a province illegally tampered with the college entrance examination volunteer by using his classmate’s admission ticket number because of his bad relationship with his classmates, which caused his classmates to be affected. The public security organ imposed a five-day administrative detention on the candidate, and the Provincial Admissions Office decided to let the victim re-fill in his volunteers to maintain the fairness and justice of the college entrance examination.

[Reminder] The college entrance examination is an important exam for candidates’ lives, and it is very important to protect the security of personal information. Candidates should carefully keep important information such as personal admission ticket number and login password, always be vigilant, avoid personal information from being leaked to others, and prevent criminals from illegally using information and infringing on personal rights and interests.

Sixth, "Zhankeng Post" is a gimmick, and the "prank" involved in the test cannot be touched.

[Case] After the math subject examination of the college entrance examination in 2023, some counseling institutions and some netizens released some pictures of the test papers, claiming to be "the test questions before the exam" and being suspected of leaking the test questions. After investigation by the public security organs, it was found that it was a malicious editor who "occupied the post". Before the exam, it posted irrelevant posts on the relevant platforms, and then replaced the original content with the content of the test paper after the exam. The post time was still displayed before the exam, which caused the illusion that it was suspected that the questions were leaked before the exam.

[Reminder] Lawyers and experts remind that if candidates maliciously publish such information, they will be suspected of breaking the law in addition to violating the examination discipline, and if the circumstances are serious, it will constitute a crime. If a training institution or other personnel, for the purpose of illegal possession, fictitiously obtains the information of test questions or "real questions" before the exam by publishing "posts occupying pits" to defraud a large amount of public and private property, it is suspected of fraud. Candidates should not "fool" themselves in order to entertain others.

Original title: "The Ministry of Education released the early warning information of the 2024 college entrance examination! 》

Read the original text

The medical documentary "Life on Earth" was praised: the real power touched people’s hearts the most.

  Recently, the documentary "Life on Earth" caused quite a shock, not only popular social networks, but also scored 9.7 on Douban after the last episode was broadcast the night before, which was described as "going against the sky". Curiously, why is such a documentary that will cause discomfort in perception popular? Can it promote the communication and understanding of the doctor-patient relationship? Some voices pointed out that at the moment when reality shows and fantasy dramas dominate the screen, it can be described as a clean stream, and the truth it shows can touch people’s hearts most.

  Do not play cards according to common sense and present death intuitively

  In the first episode, "Human Life" directly presented a failed medical case, which made people face death directly. In the film, Zhao Qiang, director of cardiac surgery department of Shanghai Ruijin Hospital, received Wang Bin, a 27-year-old patient with Marfan syndrome. This congenital disease is synonymous with "death" in the medical field. The patient’s aorta will tear at any time and he will die of massive bleeding. If you want to save him, you must replace all the aorta of the patient with artificial blood vessels, which is equivalent to "half a person has to cut it open." But he accepted the operation, but finally the next day after the operation, patient Wang Bin didn’t survive because of acute renal failure.

  The second episode "Understanding" tells the story of the 120 ambulance, which reflects various reasons for delaying the ambulance in reality.

  The ninth episode "Love" is the one that makes the audience cry the most. In the program, Zhang Lijun, 26, was married to her husband for less than a year, and was pregnant for five months, but was diagnosed with terminal cancer. At this point, the patient needs to make a decision, whether to be born or not? Finally, the patient chose to have a caesarean section when she was 7 months pregnant. The premature baby weighed just over 2 kg, but it showed great vitality. With the progress of treatment, her hair fell off and she could not see one eye. While eating the reunion dinner, the family’s mixed smiles and tears were impressive. For this reason, countless people are moved by the spiritual willpower of the parties, the great maternal love and the feelings of ordinary people.

  The audience felt: objective and positive is the best place.

  For these true stories, many viewers said that they "cried and watched the program", and many characters were memorable: "There are strong mothers who have been afraid to cry all the time, and finally burst into tears when signing and dying, and there are those who dare not write down ‘ Give up treatment ’ The shaking hands, the patient who smiled pale at the camera one second and then lay down in the hospital bed with no breath, the paramedic who slept day and night, the patient who just got a liver transplant and regained life, and the family members who were finally rescued with joy, whether it was silent tears or heartbreaking wailing, are all touching forces. This documentary truly tells us that there are many joys and sorrows in the world.

  Another audience thinks that the program reminds people to cherish the present, "How precious and fragile is life? Faced with the dilemma of choosing whether to do or not to do surgery, the pain of pious prayer but not returning to life is hidden in the film. Please realize the preciousness of life and cherish the people around you. "

  "Life on Earth" also broke the traditional plot routine of "rejuvenation with wonderful hands" in the past, and truly described the doctor’s inner pain and life struggle. Some netizens commented: "I have seen too much ‘ Perfect ’ Medical publicity, such an angle is even more touching. " Some people feel the same way: "Sometimes healing, often helping, always comforting, very objective and positive, this is the original appearance of medical care."

  The crew responded to the question:

  "There is no element of directing in advance."

  It is reported that the filming time of "Human Life" is close to two years, and it goes deep into the front line of medical treatment and operating table, intuitively showing the various situations that doctors have in the race against death. Some doctors are helpless and frustrated when they face failure, some patients say goodbye when they face the end of their lives, and some families are anxious to wait when they face the unknown. When shooting, the photographer "put on" all the equipment, even if the patient’s blood splashed on his face, he was unmoved, which is evident in the hardships.

  Despite this, in addition to word of mouth, there are also different opinions. Some people questioned that "shooting affects treatment": "It is hard to say whether shooting will interfere with the operation, and whether patients and their families will face the camera in a critical moment will aggravate their tension, which deserves further consideration."

  Others think that the documentary has the problem of emotional imbalance: "It reflects the doctor’s hard work, the harsh working environment and the mind of saving lives, trying to call for respect for doctors, but the doctor-patient relationship can not be solved simply by understanding doctors, which is a bit superficial and lacks reflection."

  The general director of "Human World" responded that "recording honestly and expressing sincerely" is the principle of the creative team. No matter whether the film is perfect or not, it must be the result of real recording, and there is no element of prior director and arrangement. Talking about the original intention of shooting, he said: "We hope to take the hospital as the origin, and show a real human world by observing the hospital, a specimen of social contradictions, with both the brilliance of human nature and the helplessness of life."

  How to shoot a medical documentary?

  Touching people’s hearts is the key.

  For a long time, due to the patient’s privacy, medical ethics, the audience’s discomfort with the picture, and the unique contradiction between doctors and patients in China, the number of medical documentary programs is small and the specific operation is very difficult, but there are also some relatively successful works.

  "Destiny of Life" broadcast by Beijing Satellite TV is a pioneer of this kind of program in China: it extends its tentacles to emergency rooms, rescue rooms and operating rooms, including both monitoring cameras and suction-type cameras installed in ambulances, rescue rooms, labor rooms and other places, from which the audience will touch the state of doctors and patients in the moment of life and death.

  The "Emergency Room Story", which had gained high reputation before, also aimed the camera at the medical scene, and its ratings were also very bright. Many people also said that it was a "work of conscience". It was shot in the Sixth People’s Hospital of Shanghai, aiming at the joys and sorrows of the emergency room, but using a fixed camera instead of a mobile camera. Doctors and patients often don’t realize that they are being filmed, so as to minimize the interruption of diagnosis and treatment. After doctors get used to it, it is difficult to hide their true emotions and daily habits, which leads to the documentary being more realistic and less deductive.

  Entertainment theory

  Accept the cruelty of life and the shock of human heart.

  Throughout our past medical film and television dramas, some of them did not truly reflect the work and life of medical staff, but dealt with them with dramatic effects, such as doctors singing and flirting in the operating room; Tell jokes to nurses while pushing patients in the emergency room; Chatting in the ward office in overalls and eating at will; There are even many loopholes in professional issues such as how to hold a scalpel. These things are not allowed in any hospital in reality.

  When the real situation of the hospital is covered by gag, many people are influenced by this kind of industry drama, which is likely to aggravate the misunderstanding of doctors and medical care.

  Seeing this, if the writers and directors in medical drama can take more snacks, carry out more field work before writing, and ask more experts during the process of writing, there will not be so many jokes in the play, and it will not help or even be detrimental to the improvement of the doctor-patient relationship.

  In this regard, it is self-evident that medical documentaries that do not shy away from the conflict between doctors and patients and adopt a real style, and it is expected that they will be supported by the audience. Of course, we can’t expect a documentary to improve the contradiction between doctors and patients much, but it at least makes us realize that in many cases, the fuse that intensifies the contradiction between doctors and patients is often not the doctor’s dereliction of duty or reckless behavior, or the poor quality of the people and the unreasonable troubles of their families, but that many people can’t accept the variables and risks in medicine, and anyone’s mood will be amplified in the face of human life. In this sense, the broadcast of this documentary enables us to "enhance our understanding through understanding". Although doctors are regarded as angels in white, they are human beings, not gods, and may run slower than "death".

  As described in the film, the patient died, but the family members were still grateful to the doctor, saying that "life must go on and we will do everything as usual". Therefore, we also need to accept the cruelty of life replacement and the shock that people’s hearts bring to everyone when facing death.
