　　Food, clothing, housing and transportation are the basic needs of life, among which "living" is regarded as just needed by many people. These two days, there was an interesting meeting, which was closely related to "living".

　　The video and telephone conference on accelerating the development of affordable rental housing and further improving the regulation of the real estate market held on the 22nd reiterated that the house should be used for living, not for speculation, and the real estate should not be used as a short-term means to stimulate the economy.

　　The positioning of "staying in the house and not speculating" continued to consolidate, which made many people eat "reassuring".

　　The picture shows a commercial house near Madang Road in Shanghai. Xinhua News Agency reporter Chen Fei photo

　　Whether buying a house, renting a house or building a house, it is inseparable from money. Therefore, real estate finance is a key link in the implementation of "housing without speculation".

　　In recent years, China has accelerated the establishment and improvement of a long-term mechanism for real estate financial management, especially under the guidance of the "three lines and four files" rule and the real estate loan concentration management system, many housing enterprises have become more cautious and self-disciplined, and the concentration of real estate loans and personal housing loans of banking financial institutions has steadily decreased.

　　In June, the sales price increase of commercial housing in 70 large and medium-sized cities showed a steady and declining trend as a whole; At the same time, at the end of June, the growth rate of RMB real estate loans in China dropped by 2.2 percentage points from the end of last year.

　　It can be seen that the regulatory policies, including real estate financial policies, have been effective, the real estate credit environment in some cities has changed, and the price increase has stabilized.

　　What is the "sharp weapon" that can make regulation so immediate? How do the "three lines and four gears" rule and the real estate loan concentration management system play a role? Come and get to know it.

　　To promote the stable and healthy development of the real estate market, first of all, real estate enterprises need to be healthy. However, some real estate enterprises are greedy for perfection and blindly expand, and the financial indicators of core operations are "red light", which also leads to the phenomenon of high leverage and high debt in the real estate industry.

　　In order to enhance the marketization, regularity and transparency of financing for real estate enterprises, in August last year, the People’s Bank of China, the Ministry of Housing and Urban-Rural Development and relevant departments formed the fund monitoring and financing management rules for key real estate enterprises, that is, the "three lines and four files" rules.

　　The "three lines" are actually "three red lines", which specifically refer to: the asset-liability ratio is greater than 70%, the net debt ratio is greater than 100%, and the cash short-term debt ratio is less than 1 times after excluding advance payments.

　　According to the situation of stepping on the line, real estate enterprises are divided into four grades: red, orange, yellow and green: the scale of interest-bearing liabilities of "red-file" enterprises cannot be higher than the existing level; The annual growth rate of interest-bearing liabilities of "orange file" enterprises shall not exceed 5%; "Yellow file" enterprises shall not exceed 10%; "Green file" enterprises shall not exceed 15%.

　　With a clear "three lines and four gears", housing enterprises must meet the corresponding requirements and constantly optimize financial indicators if they want to raise funds. This is equivalent to a "physical examination" of the financial health of housing enterprises to help them better improve their financial management.

　　Behind health is self-discipline. When the financing behavior of housing enterprises is more prudent and self-disciplined, the overall operation tends to be stable. Having tasted the sweetness, more and more real estate enterprises have joined the ranks of "self-discipline". At the beginning of the pilot, the central bank selected 12 representative real estate enterprises as the pilot targets, and at the beginning of this year it expanded to 30 real estate enterprises with large debts.

　　Zou Lan, director of the Financial Market Department of the People’s Bank of China, said that the "three-line and four-gear" rule is effective from the situation and reactions from all walks of life in the past year. The three core operating financial indicators of the pilot enterprises, namely, asset-liability ratio, net debt ratio and short-term cash debt ratio, have obviously improved, and the debt scale has steadily declined. Many other real estate enterprises outside the pilot also actively benchmark the rules and optimize their own business practices.

　　The picture shows a qionghai city resident passing by an advertising slogan in front of a bank. Xinhua news agency

　　In addition to keeping an eye on the demand side, financing management cannot ignore the supply side. In addition to monitoring and managing the liabilities of housing enterprises, the People’s Bank of China also strengthens the management of banking financial institutions — — Formulate the management system of real estate loan concentration.

　　The system sets "two red lines" for the balance of real estate loans and the balance of personal housing loans for different types and sizes of banking institutions. The former ranges from 40% to 12.5%, while the latter ranges from 32.5% to 7.5%.

　　As the saying goes, eggs can’t be put in one basket. Bank credit should also focus on structural optimization, which is not only related to the risk of the institution itself, but also of great significance to the healthy and steady development of the whole economy.

　　Since the implementation of the system, the concentration of real estate loans and personal housing loans of banking financial institutions has steadily decreased. The data shows that at the end of June, the growth rate of China’s real estate development loan balance and personal housing loan balance dropped by 3.3 and 1.6 percentage points respectively compared with the end of the previous year.

　　In Zou Lan’s view, while the real estate loan business is subject to certain constraints, commercial banks have put more energy into supporting small and micro, "agriculture, rural areas and farmers" and other weak economic links, while the proportion of loans in key areas such as manufacturing and technological innovation has been improved.

　　The data shows that at the end of June, the balance of China’s Pratt & Whitney small and micro loans increased by 31% year-on-year, and the growth rate was 18.7 percentage points higher than that of various loans in the same period; The balance of medium and long-term loans in manufacturing industry increased by 41.6% year-on-year, and the growth rate was 16.9 percentage points higher than the same period of last year.

　　The People’s Bank of China said that the next step will continue to adhere to the positioning that houses are used for living, not for speculation, implement a long-term real estate mechanism, constantly improve the "three lines and four files" rules and the centralized management system of real estate loans, do a good job in policy implementation, improve the resilience and stability of the financial system, and promote the balanced development of finance, real estate and the real economy.

　　To firmly grasp the key of real estate finance, we must continue to strictly implement the "sharp weapon" of regulation and control, manage the supply and demand ends of real estate finance, and make the regulation and control policies more precise, which will not only accurately crack down on real estate speculation, but also better meet the needs.

　　After the hustle and bustle of the day, when the night falls and the lights are on, people who like nightlife have a happy time.

　　There was a nightlife in ancient China. "Thousands of trees are blooming in the easterly night, and the stars are raining, and BMW cars are carving incense all over the road. The phoenix flute is moving, the jade pot is turning, and the fish and dragon dance all night. " In the Southern Song Dynasty, Xin Qiji’s first poem "Jade Case Yuan Xi" was inscribed, which vividly described the bright lights and crowds on the night of the last Yuan Festival.

　　Today, after urbanization has gathered a large number of people, the fast pace and high pressure of modern life have given birth to people’s need to relax and release themselves. Rich information, increased income and improved living conditions also make it more convenient to go out for consumption activities at night. Night economy is becoming a consumption force that cannot be ignored.

　　Night economy improves consumption convenience and enriches people’s lives.

　　Night economy is an important part of urban economy. The city at night has a unique charm, attracting people to wander among them.

　　Night economy mainly includes catering, shopping, entertainment, leisure, health care, education, film and television, tourism, sports, etc. When it comes to nightlife, tasting delicious food is definitely the first choice. In Guangzhou, which is famous for its delicious food, the famous night market food garden has the most famous time-honored restaurants and various garden-style restaurants in Guangzhou, and also collects old Guangzhou snacks, such as Shahefen, Seto Powder and Cantonese dim sum. Chengdu, which is famous for its leisure, and Kuanzhai Lane’s night market have both areas for displaying ancient art and culture, as well as local delicacies and snacks in Chengdu, such as Ye Erao and the Three Cannons. In the capital Beijing, going to Guijie to taste delicious food and going to Sanlitun to experience bar culture is a necessary "punch-in" trip for many people.

　　In addition to food, culture and entertainment are also essential. Movies, dramas, cross talks, concerts, art exhibitions, etc. satisfy people’s spiritual life, while various shopping centers, comprehensive shopping malls and other commercial places integrate eating, drinking, playing and entertainment, making people who are keen on shopping linger. Zou Tongqian, a professor at beijing international studies university China Institute of Culture and Tourism Industry, said that museums, exhibition halls, art galleries, concert halls, movie halls and gymnasiums are the most active places for night consumption, and there are more and more night consumption items.

　　The consumption increment brought by the night economy is also very objective. The consumption data released by Beijing Municipal Bureau of Commerce during this year’s "May 1" holiday shows that the major business districts are full of popularity, night consumption continues to heat up, catering consumption is hot, and smart and energy-saving home appliances are popular. The 60 retail and catering enterprises monitored by the commerce department realized a cumulative sales of 3.22 billion yuan, up 6.5% year-on-year. The characteristics of Beijing’s nighttime economy are prominent, and the endogenous power of consumption is active: the data shows that Wangfujing, Sanlitun and Qingnian Road lead the way in nighttime consumption from 18: 00 to 6: 00 the next day, and the catering consumption has increased by 51.3% year-on-year. The latest "Night Economy" report released by Alibaba on July 24 shows that night consumption, including catering and shopping, has gradually accounted for half of the daytime.

　　Government measures help to "give a green light" to the night economy

　　The healthy development of urban night economy can stimulate urban economic development and enrich citizens’ night life, and now it has become an important starting point for expanding consumption and promoting people’s livelihood in many parts of the country. In order to promote the development of night economy and serve the people, many governments have introduced relevant policies and measures to help the night economy according to their own conditions.

　　In the 2019 Beijing Municipal Government Work Report, it is proposed that Beijing will stimulate a new round of consumption upgrading potential this year. To this end, Beijing will implement a plan to promote consumption and introduce a series of "1+X" policies to further expand commodity consumption and service consumption. Among them, the policy of prospering the night economy and promoting consumption was introduced to encourage key blocks, shopping malls, supermarkets and convenience stores to extend their business hours appropriately.

　　"By 2022, more than half of convenience stores in Beijing will be open 24 hours a day; Each district must have at least one night economic business circle. " In an interview with the media, Yan Ligang, director of the Beijing Municipal Bureau of Commerce, revealed that Beijing will introduce a policy of prospering the night economy to promote consumption, encourage key neighborhoods, shopping malls, supermarkets and convenience stores to extend their business hours appropriately, and stimulate a new round of consumption upgrading potential.

　　In order to optimize the guarantee measures of public transport service at night, Beijing Metro Company officially implemented the delayed operation scheme on July 19th. The plan includes that every Friday working day and Saturday rest day, Beijing Metro Lines 1 and 2 will extend the departure time of the last bus to after 0: 00 am the next day.

　　The Guangzhou Municipal Bureau of Commerce recently released the Map of Night Consumption in Guangzhou, and 15 consumption gathering areas such as Beijing Road Pedestrian Street and Tianhe Road Business Circle were listed as "Night Guangzhou" consumption landmarks. According to the commercial department, Guangzhou will further enrich and meet the people’s demand for night consumption by building a gathering area for night consumption, and build Guangdong-Hong Kong-Macao Greater Bay Area into a "city that never sleeps". According to the relevant person in charge of the Guangzhou Municipal Bureau of Commerce, the next step will continue to promote agglomeration development, focusing on building many night consumption gathering areas and improving supporting facilities and public services; Create a comprehensive experiential shopping paradise for night consumption and vigorously develop experience economy, fashion economy and cross-border economy; Promote the integration and development of business travel style, and create landmark festivals and their night activities; And take the opportunity of 5G construction to promote the development of "night consumption in internet plus" and build a modern network provider.

　　In May this year, Suzhou Museum in Jiangsu Province held the "Wonderful Night of the Museum" opening activity, and the visiting time was extended to 9 pm. Visitors can not only feel the emotional appeal of Suzhou in the dark, appreciate the museum collections, but also participate in various cultural activities.

　　Cultivating night economy is a systematic project, which requires both the active guidance of government departments and the extensive participation of all sectors of society. This is also the significance of setting up "night warden" and "nightlife CEO" in some cities.

　　Developing night economy needs to fully understand consumer demand.

　　Developing night economy is not only an important way to expand new consumption areas, but also an inevitable choice to meet people’s needs for a better life. However, we should also see that the night economy brings vitality, charm and new economic growth points to the city, but it also puts forward higher requirements for the level of urban governance.

　　The development of night economy is not simply to change the business activities during the day to the night, but to take into account the living habits of local people, and the night consumption time in residential areas and surrounding areas needs to be reasonably controlled, so as not to disturb the people and affect the rest of residents. At the same time, night consumption must have the awareness of safety first.

　　Xu Guangjian, a professor at the School of Public Administration of Renmin University of China, said in an interview with the media, "Today is an era of great wealth of commodities. Consumers are faced with many choices and their consumption demands are constantly escalating. Talking about the past ‘ Night economy ’ I think of low-grade and cheap, but now people are pursuing quality and enjoyment. "

　　The data shows that in the first half of the year, service consumption accounted for 49.4% of the final consumption expenditure of all residents, an increase of 0.6 percentage points over the same period of last year. With the improvement of income and supply quality, Chinese residents’ consumption is changing from physical consumption to service consumption.

　　"With the Internet, people can spend money with their fingers at home. Why do people want to go to physical stores? Because the store can enjoy the experience and service, this is precisely the shortcoming of online shopping, and it should also be the future development ‘ Night economy ’ The focus. " Guang Xu said.

　　In fact, experiential consumption at night has become a rigid demand of people. During the Spring Festival of 2019, night experience projects such as Xi ‘an "Datang City that Never Sleeps" and Chongqing Liangjiang Night Tour were hot; This year’s Lantern Festival, the Forbidden City opened the "Night of the Forbidden City" for the first time, and as soon as tickets were sold, it was "second light" … …

　　Whether the "menu" of night consumption can be richer and give people more choices; Whether public transportation can keep up with it and provide convenience for consumers and staff who delay work; How to manage the noise and lampblack problems of night dining and avoid disturbing the residents who have a normal rest … … It can be said that how to make the night economy better light up the night sky of the city is not only an economic proposition, but also a governance test. (Zhuang Hongtao)

For 35 years, he devoted himself to the seismic research and teaching of building structures, and a new structural seismic technology was born from him and his team. He is actively committed to applying the latest seismic research results to engineering practice and escorting a number of major projects in China; He insisted on the road of international cooperation in seismic research and led the team to push China’s structural seismic research to the international stage …

He is Professor Lv Xilin, a newly-elected academician of China Academy of Engineering and an expert on earthquake resistance of building structures in Tongji University School of Civil Engineering. In November 2015, he won the "Science and Technology Progress Award" in ho leung ho lee foundation. In February 2017, he was awarded the Newmark Award by the American Society of Civil Engineers.　　

Determined to do seismic research of buildings

This is a scene of the disaster area three days after the Wenchuan earthquake.

Here is a unit building in Qingchuan County, which was seriously affected by the disaster. The building is covered with numerous cracks. A burly middle-aged man is fearless, and the cat is the first to get in, looking at the damaged structure everywhere.

He is Professor Lv Xilin, the head of the expert group of Tongji University, the first batch of housing emergency assessment in Wenchuan earthquake-stricken areas of the Ministry of Housing and Urban-Rural Development. He volunteered at the first time after the disaster and rushed to the front line of earthquake relief.

Looking back more than 40 years ago, in 1976, when the Tangshan earthquake occurred, he was a sophomore in Xi ‘an Institute of Metallurgy and Architecture (now Xi ‘an University of Architecture and Technology), majoring in "Industrial and Civil Architecture". At that time, Xi’ an also had an obvious earthquake. "The earthquake caused so many houses to collapse in an instant and took so many living lives, which touched my heart very much." Lv Xilin recalled, "From then on, I was determined to go to graduate school and concentrate on seismic research of buildings."

After graduating from college, he wished to enter Tongji University, which has the highest strength in earthquake resistance in civil engineering in China, to study for a master’s degree in structural engineering. In March, 1982, he continued to study for a doctorate in structural engineering at Tongji University, under the guidance of Professor Zhu Bolong, a well-known expert from Tongji University. The topic of his thesis is the seismic research on a large number of masonry structures in China. He also became the first batch of doctoral students after China resumed the postgraduate enrollment system.

In December 1984, Lv Xilin successfully passed the defense of doctoral thesis and became the first doctoral student in structural engineering in Tongji University.

"There are still many unsolved problems in the field of building earthquake resistance, and there are still many unknown phenomena waiting for us to explore." Young Lv Xilin, with the enthusiasm of scientific exploration, embarked on the journey of seismic research of building structures.　

Play a good job in the new technology of structural earthquake resistance "combination boxing"

This is a building in Dujiangyan. In the middle of the first and second floors, a structural member with a length of about one meter can show its talents when a strong earthquake strikes. It absorbs and consumes the energy released by the earthquake, so that it no longer strongly impacts the house; Its seismic fortification intensity is increased from 7 degrees to 8 degrees. This is a new type of structural seismic device-"damper" installed on the H-shaped steel support, which comes from Lv Xilin’s team and has been widely used in the restoration and reconstruction project of Wenchuan earthquake-stricken area, the seismic safety project of national school buildings, and other important projects such as Shanghai Ganghui Square.

"Traditional reinforcement is generally to thicken the beams and columns of the building, which not only has a long construction period and high cost, but also shrinks the housing area." Professor Lv Xilin said that the adoption of new brace+damper technology not only greatly improved the seismic capacity of buildings, but also saved a lot of engineering time and cost.

In fact, the team played the "combination boxing" of structural earthquake resistance: "rubber bearing+sliding bearing+viscous damper". The "isolation bearing" is installed between the building foundation and the foundation. When the earthquake occurs, the bearing shakes, dissipates energy and reduces vibration, while the building on it is motionless, so it is soft and rigid. The flexible and innovative combined isolation and vibration reduction system has been successfully applied to major projects of Shanghai International Circuit and more than ten foreign construction projects.

He insisted that the research results should be closely combined with the actual project: "We are not seeking technology for technology’s sake, but we should fully consider how to make the seismic structure system more reasonable and safer, the construction easier and the project cost lower."

Team Lv Xilin pays close attention to the safety of complex high-rise buildings. Most of these over-code high-rise buildings are particularly complex in shape, changeable in internal space and ever-changing in structure, which poses great seismic challenges to their structures. Over the past 20 years, Professor Lv Xilin led the team to continue in-depth research and made new breakthroughs in the theories and methods related to seismic analysis and design of complex high-rise buildings. The results have been applied to the seismic design and performance evaluation of more than 50 major or key projects in China, such as Shanghai Tower and Shanghai World Financial Center.

The team’s technical achievement of "one lifting, two moving and three strengthening" to improve the seismic performance of existing buildings has also been successfully applied to the relocation and reconstruction of outstanding historical buildings such as Shanghai Concert Hall and Shanghai Jade Buddha Temple Daxiong Hall.

He often teaches students: "Don’t be bound by the existing seismic technology of structures, or even be bound and restricted by the existing codes." For more than 30 years, he led the team, constantly exploring, developing and breaking through the existing seismic technology of building structures, and won the second prize of national scientific and technological progress and the second prize of national technological invention …

As early as more than ten years ago, he began to pay attention to and introduced the concept of "recoverable earthquake-proof structure" for the first time in China. Since then, he has led the team to invest a lot of time in tackling key problems, and the results have attracted the attention of international peers.

"Teacher Lu’s high sensitivity to the new structural seismic technology, his accurate grasp of its future development direction, and his tenacious spirit of persisting in the identified fields all make our students admire and feel ashamed." His student Professor Li Peizhen lamented this.

In tackling key problems in scientific research, Lv Xilin never forgets to teach and guide students. "Earthquake resistance and disaster prevention is a public welfare undertaking, and we must have dedication." "The engineering anti-seismic technology is regional, and we must develop new technologies in combination with China’s actual situation." In recent years, many doctoral students he trained and supervised chose to work in Xinjiang, Northwest China, Southwest China and Northeast China when they graduated.　

Promote international cooperation in the field of earthquake engineering

Walking in Building B of the Civil Building where the Department of Structural Disaster Prevention and Mitigation Engineering is located, you can often see young students from abroad exchange and study here.

In April this year, Tongji University Joint Laboratory for International Cooperation in Earthquake Engineering successfully passed the acceptance demonstration organized by the Ministry of Education, and experts recognized its construction achievements.

In July 2015, the "Joint Laboratory for International Cooperation in Earthquake Engineering" was established in Tongji University, bringing together the strengths of China, the United States, Japan and Italy to jointly carry out research on major international frontier earthquake-resistant scientific issues. Lv Xilin is the director of the Academic Committee of the Joint Laboratory, which is also the fruit of his decades-long adherence to the road of international cooperation.

The internationalization characteristics of Tongji academic had a deep understanding during Lv Xilin’s study in Tongji Garden.

After staying in school after graduation, Lv Xilin took the initiative to go out and keep in close contact with international colleagues. Tokyo institute of technology, University of California, Berkeley, Italian European Earthquake Engineering Research Center and other internationally renowned earthquake engineering research centers have all formed friendly cooperation partners with him.

After the Wenchuan earthquake, Lv Xilin established the Guanghua Academic Forum in the field of earthquake engineering. In the past 10 years, the forum has been held for 8 times, and a group of colleagues from the field of earthquake engineering at home and abroad gathered in Tongji for each session to exchange the latest research progress.

In September 2011, Lv Xilin became the new editor-in-chief of the international academic journal "The Structural Design of Tall and Special Buildings". This is the first time that a China scholar has been the editor-in-chief of the magazine since it was founded more than 20 years ago. In 2017, he was awarded the Newmark Award by the American Society of Civil Engineers. Established in 1975, this prize is awarded once a year, and each time a scientist who has made outstanding contributions in the field of structural engineering and engineering mechanics is selected worldwide. Lv Xilin is the first China scholar to receive this honor.

He also actively encourages and subsidizes postgraduate students and doctoral students to boldly make presentations at international forums. His doctoral supervisor, Professor Ying Zhou from Tongji University School of Civil Engineering, felt deeply "benefited from this". During his doctoral studies, Ying Zhou had the opportunity to give an academic report in international forums. After staying in school, she went to Berkeley to carry out project cooperation, and grew up all the way on the academic road. Now she has become the vice chairman of the International Society for Disaster Reduction and Control, the winner of the National Natural Science Foundation’s outstanding youth fund, and the director of the structural disaster prevention and mitigation engineering department of Tongji University.

"We can proudly say that the scientific and technological level of earthquake resistance and disaster reduction in China has been ranked among the first corps after the United States and Japan, and the gap is narrowing. We are mainly lacking in the fineness of product manufacturing and earthquake research." Professor Lv Xilin said that the International Joint Laboratory focused on civil and infrastructure projects, major construction projects, long and long bridge structures, lifeline projects, long and long tunnel structures, deep-water foundations and large-scale energy facilities that can recover their functions after the earthquake. In the past three years, it has released 14 research topics to the world, and achieved results in discipline construction, talent training and introduction, international cooperation and collaborative innovation.

"Structural earthquake prevention and disaster reduction, there are still many things to do. I will stick to my original heart and continue to go in the direction we are looking for with the team. " Looking to the future, he is still full of confidence. (Ai Jiao)

　

　　The scene of the derailment accident of the "poison train" in Ohio, USA (data map)

　　Overseas network April 12 thAccording to the Associated Press reported on April 11, after the "poison train" accident in East Palestine, Ohio, the soil and liquid containing toxic chemicals in the accident site are being transported to Michigan for storage. This news made local residents and politicians angry.

　　A local official in Michigan said: "People have seen photos of the scene of the accident in Ohio before, and they saw smoke and wild animals dying. It is terrible that people have heard that local residents have health problems. Now, (toxic substances) are entering our community. " Due to strong protests, the US Environmental Protection Agency was forced to interrupt the transportation of toxic substances at the scene of the accident.

　　In addition to Michigan, in Indiana, Oklahoma, Maryland and other places, the voice of refusing to accept the "toxic train" accident waste continues to rise. The EPA responded that States should not interfere with federally authorized waste transportation.

　　Nevertheless, local governments are still trying their best to avoid receiving toxic waste. A company tried to discharge the liquid from the accident site into the wastewater system in Baltimore, Maryland, but the plan was aborted because of the obstruction of the mayor of Baltimore.

　　At present, Ohio officials are putting pressure on the railway company and the US Environmental Protection Agency to remove contaminated soil and liquid. There were 24,400 tons of soil to be treated at the site, some of which had been transferred to three treatment facilities in Ohio and facilities in Michigan, Indiana and Texas. However, protests broke out after that, which interrupted the transportation of toxic waste. (Overseas network Liu Qiang Intern Shang Ruiwen)

Trudeau participated in the "Pride Parade". Oriental IC diagram

According to the British "Guardian" report, on July 3, local time, Toronto, Canada held a "pride parade" aimed at promoting gay equality and liberation, which is one of the largest "pride parades" in Canada.

Canadian Prime Minister Justin Trudeau appeared in the parade that day. A young man wearing a white vest beside him also attracted widespread media attention.

According to reports, this man is a Syrian refugee named Bashir McLeish. He is 29 years old and was originally an airline employee in Damascus. Bashir McLeish is a homosexual and HIV carrier.

He told the Canadian Broadcasting Corporation (CBC) that he was completely shocked when he found that the Canadian Prime Minister was with him in the parade.

"For me, the concept of’ pride parade’ is a dream in itself, and being able to participate in this parade is more like dreaming. As for being able to participate in this parade next to the Canadian Prime Minister, I have never dreamed of it in the wildest dream." He said.

According to the Guardian, in the middle of the parade, McLeish finally got up the courage to talk to Trudeau. He thanked Trudeau and the Canadian government for their decision to take in refugees. Trudeau said that his decision was based on the wishes of the Canadian people.

According to CBC, at the beginning of the civil war in Syria, the first destination where McLeish fled was Egypt. There, he returned to his old job and started the work of fuel coordination. However, his work unit refused to sign a labor remuneration contract with him, which led to his loss of his job. In addition, he was found to have HIV in 2014, and Egyptian law prohibits foreigners with HIV from working in Egypt, which makes his situation worse.

However, a Canadian-based NGO "Rainbow Silk Road" noticed him, and with the support of this organization, McLeish arrived in Canada in May this year and started a new life. "Rainbow Silk Road" focuses on helping sexual minorities (LGBT) from Syria get out of trouble.

According to the Guardian, after taking office at the end of 2015, Trudeau and his Liberal government announced that they would welcome Syrian refugees and said that they would provide assistance to the areas receiving refugees. At the same time, Trudeau also vigorously promoted the development of LGBT affirmative action after he took office.

In May this year, Canada announced the adoption of legislation to prohibit discrimination, insult and violence against transgender people. Anyone who publishes "hate speech" to transgender people based on gender will be punished by law.

Trudeau said at the time: "I sincerely believe that Canada can and must do more (in promoting affirmative action). This is not only for ourselves, but also for setting an example to the rest of the world. An open and free society is the greatest thing we can aspire to. "

In addition, according to the data of official website, the Canadian government, 28,640 Syrian refugees have arrived in Canada.

　　Quanjiao County Water Conservancy Bureau set up a temporary pumping station to reserve source water for city and county waterworks. Quanjiao county news ketu

　　This year, Quanjiao County, Anhui Province suffered a once-in-60-year drought, and the water level of Huanglishu Reservoir continued to decline. Recently, the Chuzhou Flood Control and Drought Relief Headquarters issued the opinion of "Diversing the River into the Chu River", and the Quanjiao County Water Conservancy Bureau diverted water to fight drought.

　　Yuan Changqing, director of the Water Conservancy Bureau of Quanjiao County, said, "The so-called diversion of the Yangtze River into the Weihe River means that the Yangtze River water is first introduced into the Weihe River, and it is sent up by the four-stage pumping station we set up, and finally the water is sent to the second water plant in Quanjiao County and the third water plant in Chuzhou City."

　　Overlooking Huanglishu Reservoir in Quanjiao County, Anhui Province, a large area of water surface has dried up to the bottom. Quanjiao county news ketu

　　The Paper learned from the news department of Quanjiao County that the total rainfall in the six months before and after the flood season was 372 mm, which was more than 50% less than the average of 715 mm in the same period of many years. The total storage capacity of 104 reservoirs and ponds in the county was 60% less than that in the same period of last year, and the bottom water was seriously insufficient. In particular, the water storage capacity of Huanglishu Reservoir, Machang Reservoir and Sanwan Reservoir is seriously insufficient.

　　It is reported that the main forms of decentralized water supply in this county are shallow well water and mountain spring water. The continuous drought has caused the well water and mountain spring water in some remote mountainous areas of this county to dry up, which has caused difficulties for drinking water for 626 villagers in local towns such as Machang Town and Shizi Town.

　　At 10: 00 am on November 9, Anhui Flood Control and Drought Relief Headquarters upgraded the emergency response level of drought relief to level III.

　　According to the information department of the county, since October, the water level of Huanglishu Reservoir, which is called "Quanjiao People’s Water Tank" in the county, has been continuously declining, resulting in the shortage of water supply for nearly 700,000 urban residents and rural population in Chuzhou and Quanjiao County.

　　Xiwang Water Plant in this county has been taking water from Daishan Lake, but it can’t get water because of the low water level in Daishan Lake. Liu Guoxiang, the person in charge of Xiwang Waterworks, said, "30,000 people are facing waterless drinking, and we are in a hurry. The county water conservancy department coordinated the water conservancy department of Feidong County and gave us an earth dam more than 80 meters long and more than 30 meters wide in the lower reaches of Daishan Lake, which solved our water intake problem."

　　On October 18th, Chuzhou City issued the "Implementation Opinions on Water Diversion from River to Chuhe", and the county started the emergency water diversion work.

　　The head of the news department of Quanjiao County told The Paper that the emergency water replenishment plan for the Quanjiao section of "Diversion from the River to the Chu River" will cost about 14 million yuan, and it is expected that the project will come into play in late November.

　　According to Xinhua News Agency, it was learned from the office of Anhui Flood Control and Drought Relief Headquarters on November 12th that Anhui Province is suffering from the worst drought in summer and autumn in recent 40 years. 1452 reservoirs in the province dried up. Anhui province has sent more than 30 working groups to guide grass-roots drought relief.

　　With the country’s efforts to crack down on online telecom fraud, criminals are constantly renovating fraud. We have sorted out several recent scams, hoping that the public will constantly improve their anti-fraud skills and not give criminals an opportunity.

　　Scam 1: Pick up the lottery ticket and scrape out the "grand prize"

　　Walking on the road, I suddenly found a "grand prize lottery ticket". Did a pie fall from the sky?

　　For this kind of false lottery fraud cases, anti-fraud experts pointed out that swindlers distributed so-called "grand prize lottery tickets" everywhere, so as to attract people’s attention. Once someone was carried away by the "grand prize" and dialed the "redemption" phone number, they were likely to be cheated into paying "handling fees" and "bonus tax", causing economic losses. In addition, some lawless elements will "make a full set of plays" and create fake lottery websites in advance to dispel users’ doubts, thus tricking more people into being fooled.

　　Scam 2: Lie that you lost the courier and asked to add WeChat.

　　Recently, a new deception of posing as a courier company staff fraud appeared.

　　The fraudsters first pretended to be employees of the courier company and claimed to have lost the victim’s courier, intending to pay full compensation to the victim. Then, let the victim add WeChat.

　　In WeChat, the victim is first induced to borrow money online, and then a link with Trojan virus and a QR code are sent to the victim for connection, so that the virus in the victim’s mobile phone can defraud money.

　　Scam 3: wayward "boss" madly sends red packets.

　　"Never send it to the whole network in cash-filled red envelopes", "You can take the cash prize with a little finger forwarding" and "The boss gave money willfully on the tenth anniversary of a certain enterprise" … … Various exaggerated titles of "WeChat red envelopes" became popular in the WeChat group.

　　This kind of red envelope is different from ordinary red envelopes. After opening, it is not a cash-filled red envelopes, but a web link. To display a red envelope on a webpage, you need to share the red envelope link in multiple WeChat groups first. In order to show the authenticity of the red envelope, the words "XXX has successfully cashed out RMB" are often attached at the bottom of the webpage.

　　In fact, this kind of external red packets are mostly marketing advertisements, the purpose of which is to induce users to forward the web links that come with the red packets. However, there are also scammers who will not let you go after sharing, and will continue to induce users to participate in "preferential recharge activities". The result is often that the recharge is false, and the fraud is true. Moreover, in this process, once the user fills in the mobile phone number and other information, personal privacy may be exposed.

　　Not only is it risky to receive red envelopes, but you should also be careful when giving them. Send 30 to 60, send 500 to 1000, and you can get a double return when you send a red envelope in the group. Such a "good thing" should be careful of hidden traps. This kind of rebate behavior is very popular in QQ group and WeChat group recently. Some fraudsters set up so-called red envelope groups. In fact, 9 out of 10 people in the group are childcare. In addition, fraudsters will enhance the authenticity by forging a series of transfer records, and induce the victims to step into the trap step by step. After the victims send large red envelopes, the other party will directly pull the black, or let the victims continue to transfer money or send red envelopes on the grounds that the system is not received, causing more losses.

　　Scam 4: Fudge investment in the name of "virtual currency" and "blockchain"

　　Recently, a photo of a Chinese aunt posing at the blockchain conference became popular in the circle of friends, and netizens commented that the aunts had been targeted by the blockchain. Since the beginning of this year, some criminals have carried out pyramid schemes under the banner of blockchain finance, which has become one of the latest variants of pyramid schemes.

　　With the development of blockchain technology, various virtual currencies have emerged, and many of them are scams. Liars carry out pyramid schemes in the name of "virtual currency" and "blockchain", mainly to grasp the psychology of ordinary investors who don’t understand virtual currency and blockchain, but hope to catch up with the virtual currency investment boom. Its scams are often complicated and investors are easily fooled. Moreover, it is difficult to recover its investment after being fooled.

　　Experts remind that various virtual currency platforms generally promote technologies such as "blockchain" and "decentralization", and some are also named after international organizations and multinational financial groups, which is extremely confusing. Middle-aged and old friends must invest carefully and it is best not to set foot in unfamiliar investment fields.

　　Scam 5: Making the "Public Security Bureau" APP to deceive people into entering bank card information.

　　Different from the telecom fraud that used to pretend to be a public security officer, the swindler in this new telecom fraud made an "Intelligent Police System of the Public Security Bureau" APP that was confusing enough to trick the victim into entering information such as bank cards to defraud funds.

　　According to the police, the phishing APP made by scammers has the functions of "call transfer" and "SMS interception", which deliberately blocks the communication between the police and the victims. At the same time, the APP basically includes all prime bank in China, and does not require the victim to transfer money across banks or through online banking. Once the deceived person inputs the bank card number, ID card, mobile phone number, login password and transaction password, his bank account is basically in a "streaking" state.
