Cctv newsRecently, some mobile phone users reported that when some mobile phone apps were opened, the mobile phone automatically started taking photos or recording, and it was suspected that sneak shots were taken. These two incidents that may involve revealing personal privacy quickly attracted public attention.

　　In order to realize the full-screen design, the mobile phone in the report video designed the front camera as a lifting and hiding function. The whistleblower said that when he opened the QQ mobile browser, the camera of the mobile phone suddenly rose out by himself, and he was suspected of being photographed or secretly recorded. This video quickly became a hot search on the internet that day, and caused strong dissatisfaction among netizens about the suspected sneak shots of mobile apps.

　　In this regard, the QQ browser team quickly issued an official statement, saying that there is indeed an action of raising the camera, but this is just that the APP wants to obtain the parameters of the camera in order to support the QR code scanning, and will not turn on the camera, let alone shoot or record, and explain the cause of the problem and the technical principle for this abnormal phenomenon. The statement also stated that the mobile QQ browser will not collect any privacy of users, and will optimize the user’s experience and experience.

　　Coincidentally, a few days later, some netizens reported that when using Baidu input method to search web pages in Baidu browser on mobile phone, the top of mobile phone showed that Baidu input method was recording. Similarly, the Baidu mobile phone input method team responded at the first time, saying that this phenomenon was caused by the optimization of voice microphone preheating, in order to speed up voice startup. He also said that Baidu input method will not record without the user’s consent at any time, nor will it collect privacy by any means.

　　For Tencent and Baidu’s statements, many netizens said that they did not sneak shots. Why did they start the camera? Why don’t you steal the recording? If the camera is not designed to be mechanically lifted, we are still unconscious of this problem; Some netizens questioned that even if the camera parameters are read for scanning the QR code as stated in Tencent’s statement, is it necessary to use the front camera?

　　The reporter contacted Tencent and Baidu through various channels, hoping to interview the relevant events. Tencent’s public relations staff declined after several detailed telephone conversations with reporters and learned the specific interview content, while Baidu made it clear that the official statement would prevail and refused the reporter’s interview.

　　Multi-user authorization of mobile APP routine is "agreed"

　　The successive incidents of mobile phone apps suspected of sneak shots have once again triggered public concern about the protection of personal information. Nowadays, mobile APP is like a double-edged sword, which brings convenience to our lives, but also lays a great security risk.

　　APP routine 1: automatically check the agreement

　　The reporter randomly downloaded a number of commonly used mobile APPs in the APP stores of Android and Apple phones, respectively, and found that after downloading the mobile APP, a line of fine print will be displayed at the bottom of its registration page to remind users that they need to read and check the User Agreement and Privacy Policy before using the app, and they can only be used normally after being authorized successfully. Many apps are automatically set to checked and default consent status without waiting for users to read.

　　APP routine 2: the user agrees to authorize when logging in.

　　Some apps are marked at the bottom of their registration page, and users only need to log in to indicate authorization. These mobile apps either require users to agree to share personal information with third parties in the privacy policy, or simply use third-party software to log in, and provide multiple third-party platforms such as WeChat and Weibo on the login page. In order to save trouble, users usually click on the third-party platform to log in quickly, but unconsciously choose the default authorization.

　　APP routine 3: Explain that the words are too long and obscure

　　After clicking on the Privacy Policy and User Agreement of a variety of mobile apps, the reporter found that many instructions are not only lengthy but also obscure, which is time-consuming and laborious to read.

　　APP routine 4: indiscriminate use of personal information has become a common phenomenon

　　The reporter’s investigation found that at present, the APPlication rights of mobile APP generally involve a number of personal information, including reading location, phone number, camera, SMS, address book, microphone, sports data, body sensor and other sensitive information. Once these rights are agreed, it means that the app can read relevant information at any time without user’s confirmation, which also explains why users start the camera and recording function when using mobile apps such as QQ browser and Baidu input method. Once the user refuses the authorization of some so-called core information, he can’t use the APP normally. For example, when using Sina Weibo, the user must agree to telephone authorization, which includes the right to read the user’s call records, otherwise it cannot be used; When using Baidu mobile phone input method, the application reminds users that they may collect all the words of users, including personal data such as passwords and credit card numbers.

　　According to the Survey Report on the Protection of Internet Users’ Rights and Interests in China 2016 released by internet society of china, from the second half of 2015 to the first half of 2016, the economic losses suffered by Chinese Internet users due to spam messages, fraudulent information and personal information disclosure reached 91.5 billion yuan.

　　Expert: Combating information leakage needs to be severely punished.

　　As early as 1995, the European Union promulgated the Directive on the Protection of Personal Data, and on May 25th this year, the European Union promulgated the most stringent General Data Protection Regulation, which stipulated that data controllers and processors providing services to European users could be fined up to 20 million euros or 4% of the global turnover in the last fiscal year in case of serious illegal data processing. Take Google as an example. In 2017, Google’s total global revenue was $110.8 billion. Assuming that it leaked users’ personal privacy and other illegal acts, the EU could impose a maximum fine of more than $4.4 billion on Google. In China, if an individual illegally obtains other people’s privacy, such as stealing photos, etc., according to the Law on Public Security Administration Punishment, if the circumstances are serious, he will be detained for more than 5 days and less than 10 days, and 500 yuan will be fined: if a business entity leaks personal information, he will be fined up to 1 million yuan according to the Cyber Security Law.

　　On August 20th, China Internet Network Information Center (CNNIC) released the 42nd Statistical Report on Internet Development in China. As of June 30, 2018, the number of netizens in China reached 802 million, and the Internet penetration rate was 57.7%.

　　The amount of basic resources has increased steadily, and the application of resources has maintained a growing trend.

　　As of June 2018, the number of IPv6 addresses in China was 23,555 /32, an increase of 0.53% in half a year. Since the release of the Action Plan for Promoting the Scale Deployment of Internet Protocol Version 6 (IPv6) in November 2017, China’s operators have basically been able to support IPv6 at the network level, and are promoting the transformation from network capability to application popularization. China’s international export bandwidth is 8,826,302Mbps, with a half-year growth rate of 20.6%. Internet users have faster Internet access, better quality of cross-border roaming calls and better network quality. At the same time, mobile Internet access traffic and the number of apps both achieved significant growth in the first half of 2018.

　　The number of netizens in China exceeds 800 million, and the popularization of the Internet has achieved remarkable results.

　　As of June 2018, the number of netizens in China reached 802 million, and the Internet penetration rate was 57.7%.

　　Shared travel users grew rapidly and market resources were further integrated.

　　In the first half of 2018, 30.6%, 43.2% and 37.3% netizens used bike-sharing, reserved taxis and reserved special cars/express trains respectively, and the number of users increased by 11.0%, 20.8% and 26.5% respectively compared with the end of 2017. The bike-sharing market has returned to the multi-strong competition pattern from the top two at the end of 2017. Bicycle companies have tried to expand their revenue sources in various ways and started to provide deposit-free services to avoid risks. Cross-border integration has occurred in the network car industry, and platform enterprises have made a comprehensive layout around the field of travel services, starting from a single business to a platform-based ecological expansion.

　　Nearly 60% of netizens use online government services, and the intensive process of government websites has accelerated.

　　Important progress has been made in emerging technologies in the information field, and industrial applications have been steadily advanced.

　　In the first half of 2018, China’s emerging technologies in the information field, such as quantum information technology, communication between heaven and earth, brain like computing, artificial intelligence, supercomputers and industrial Internet, developed well. China has a layout in quantum chips, quantum programming and quantum software. The integration process of information network between heaven and earth has been accelerated; Brain like computing chip products with independent intellectual property rights were launched; Artificial intelligence online retail stores, family and children’s education, old-age care, housework, medical health, investment risk control and other scenarios quickly landed; Supercomputers have made breakthroughs in self-control, peak speed, continuous performance and green indicators; Enterprise information systems have further migrated to cloud platforms, and industrial Internet platforms have developed rapidly.

　　On the morning of July 11th, an order worth 140 million yuan was delivered, and a new order worth 100 million yuan was received immediately. Since July, the industrial-grade mixed oil products of Sichuan Jinshang Environmental Protection Technology Co., Ltd. have ushered in an export explosion period. Even if the output is 200,000 tons at full capacity this year, there are still orders of more than 2 billion yuan that cannot be met. What is even more surprising than the order is that the industrial-grade blended oil purchased by overseas buyers is actually purified from China kitchen waste oil, and they will eventually "transform" into bio-aviation kerosene.

　　It is understood that bio-jet fuel is made of a variety of animal and vegetable oils and fats, and after technical treatment, it becomes sustainable aviation fuel, which has been used on some routes in Europe and America. Since the end of last year, the demand of European and American countries to import industrial-grade blended oil products from China has surged, and bio-jet fuel has been produced as raw materials.

　　Why has the purified food waste oil from China become a "hot potato" abroad? Bio-jet fuel is considered to be one of the best ways to reduce aviation carbon emissions, which is more than 80% lower than that of traditional aviation fuel. According to a new regulation of air transport industry passed by the European Parliament last year, the sustainable aviation fuel used by aircraft departing from EU airports should account for 2% of the total fuel by 2025, 20% by 2035 and 70% by 2050.

　　"China is the world’s largest producer of kitchen waste oil, and the application of bio-jet fuel has created an opportunity to turn waste into treasure." Ye Bin, the general manager of Jinshang Environmental Protection Technology Co., Ltd., and his team conducted in-depth research and found that compared with American enterprises producing bio-jet fuel mainly from corn oil and European enterprises producing bio-jet fuel mainly from rapeseed oil, the production cost of kitchen waste oil is not only lower, but also the maximum carbon emission reduction value can be obtained in the process of converting it into bio-jet fuel.

　　On Ye Bin’s desk, there are four glass bottles, which are filled with leftover hot pot oil, industrial-grade mixed oil after physical purification, chemically synthesized first-generation biodiesel and bio-jet fuel. This is also the whole process of kitchen waste oil "transforming" into vehicle fuel and bio-jet fuel. "After purchasing waste oil from restaurants, slaughterhouses and food processing plants, the key step is to extract industrial-grade mixed oil that meets the requirements. This raw material pretreatment technology is the core competitiveness. " Ye Bin revealed that with the technology of precipitation for more than 20 years, his team has recently successfully increased the conversion rate of industrial blended oil to 98%, and the conversion rate of bio-jet fuel to 75%, which is at the leading level in the world.

　　At present, China produces tens of millions of tons of kitchen waste oil every year, but it has not been converted into bio-jet fuel on a large scale in China, achieving greater economic value. Not long ago, Ye Bin’s team did another great thing: Sichuan and Chongqing are one of the main sources of waste oil in China. They invested 1.5 billion yuan to build a bio-jet fuel production base with an annual output of 400,000 tons in Sichuan, creating a whole industrial chain from recycling kitchen waste oil to converting bio-jet fuel. It is estimated that after the project is put into production next year, the export products of Jinshang Environmental Protection Technology Company will change from industrial mixed oil to bio-jet fuel, which is expected to realize large-scale export of bio-jet fuel.

　　The aging in China is accelerating, but the situation faced by different regions and cities is quite different.

　　According to the internationally accepted classification standards, when a country or region accounts for more than 7% of the population aged 65 and over, it means aging; Reaching 14%, it is a deep aging; If it exceeds 20%, it will enter a super-aging society.

　　According to the data of the seventh national census, the First Financial Reporter combed the population age composition of 336 cities at or above the prefecture level (including municipalities directly under the central government, cities with separate plans, provincial capitals, ordinary prefecture-level cities, prefectures and leagues outside Sansha City, hereinafter referred to as "cities") except Sansha City, and found that 149 cities in China have entered a deep aging stage, in the northeast, Chengdu-Chongqing urban agglomeration, the middle and lower reaches of the Yellow River and the central region.

　　149Urban deep aging

　　The data shows that in 2020, the proportion of 149 prefecture-level and listed people aged 65 and above has exceeded 14%, entering a deep aging.

　　In terms of regional distribution, among the 149 cities, 41 are from the eastern coastal areas, accounting for 27.5%; There are 36 in Northeast China, accounting for 24.2%; There are 72 in the central and western regions, accounting for 48.3%. Generally speaking, the cities with deep aging are concentrated in the northeast, the central region, the Yangtze River Delta, the middle and lower reaches of the Yellow River and Chengdu-Chongqing urban agglomeration.

　　From the perspective of provinces, 149 cities are distributed in 22 provinces, of which 7 provinces have more than 10 cities with deep aging. Among them, there are 17 deeply aging cities in Sichuan, ranking first in number. This is mainly because there are a large number of prefectures and cities in Sichuan, and the population of prefectures and cities not only flows to the developed coastal areas, but also flows into Chengdu with the rapid economic development of the provincial capital in recent years.

　　According to the data, Chengdu is the only provincial capital city and sub-provincial city with a population exceeding 20 million, ranking fourth among all cities in China after Chongqing, Shanghai and Beijing. In 2020, the resident population of the seventh national census in Chengdu reached 20,937,800, accounting for 25.02% of the total resident population in the province, which was 6.22 percentage points higher than that of the sixth national census in 2010 (including Jianyang, the same below); Compared with 2010, it increased by 5,818,900 people, an increase of 38.49%, with an average annual increase of 581,900 people, with an average annual growth rate of 3.31%, which was 0.18 percentage points higher than the average annual growth rate in the last decade.

　　According to the First Financial Reporter, the increase of 5,818,900 people in Chengdu ranks third among all cities in China, second only to the first-tier cities of Shenzhen and Guangzhou.

　　According to the analysis of Sichuan Provincial Bureau of Statistics, in the past ten years, the population of the whole province has further gathered in Chengdu, the first city. From the city (state) data, the population tends to gather in the central city. The data shows that, divided into five economic zones, compared with the sixth national census in 2010, the proportion of permanent residents in Chengdu Plain Economic Zone and Panxi Economic Zone increased by 4.25 percentage points and 0.10 percentage points respectively, while the proportion of permanent residents in South Sichuan Economic Zone, Northeast Sichuan Economic Zone and Northwest Sichuan Ecological Demonstration Zone decreased by 1.44 percentage points, 2.74 percentage points and 0.17 percentage points respectively.

　　Similar situations exist in Hunan, Anhui and Hubei in the middle reaches of the Yangtze River. For example, there are 12 cities in Hunan and Anhui in central China that are deeply aging, and there are also 9 cities in Hubei. One of the main reasons is the outflow of young and middle-aged people, and the working-age population accounts for a relatively low proportion, so the elderly population accounts for a high proportion.

　　Julia, a professor at Zhongnan University of Economics and Law, analyzed the First Financial Report. The central region is closer to the Yangtze River Delta, the Pearl River Delta and Beijing-Tianjin-Hebei. In recent years, the construction of high-speed rail network has further shortened the time and space distance. In addition, with the rapid development of several strong provinces in central China in recent years, there are many employment opportunities, and many cities have moved to provincial capitals.

　　Therefore, the age structure of Sichuan and the capital cities of the central populous province is still relatively young. The proportion of people aged 65 and above in provincial capital cities is mostly below 14%, and the proportion of working-age population is still relatively high.

　　In contrast, the degree of aging in Northeast China is deeper. According to the data, there are 36 cities in the three northeastern provinces, all of which have entered the stage of deep aging.

　　Yi Baozhong, a professor at the Northeast Asia Research Institute of Jilin University, analyzed the First Financial Report. The enterprises in Northeast China are mainly state-owned enterprises, and many employees are in state-owned enterprises and administrative institutions, so family planning is strictly implemented. In addition, the industrialization in Northeast China is early, the urbanization rate and education level are relatively high, and the concept of raising children and preventing old age similar to that in rural areas is relatively indifferent. In addition, Northeast China is an immigrant society, which is less influenced by the traditional concept of fertility, and the overall population birth rate and fertility rate are relatively low.

　　According to Yi Baozhong’s analysis, due to the economic downturn in Northeast China in recent years, there are not many employment opportunities, so young people continue to flow out. Whether they are admitted to universities or not, many people go to the southeast coast for employment, which will also affect the age structure of the population.

　　Guangdong, Fujian and other places have a low degree of aging.

　　There are also many deeply aging cities in Shandong, Jiangsu and Zhejiang in the east. Among them, 14 of the 16 cities in Shandong province have entered the deep aging, and the other two cities, Zaozhuang and Liaocheng, are also very close to the standard of deep aging. At present, Shandong’s population aged 65 and over has reached 15.36 million, making it the province with the largest total elderly population in China.

　　From the perspective of three age groups, Shandong has the characteristics of "high at both ends and low in the middle", that is, the working-age population accounts for a relatively low proportion, and the elderly population and children population account for a relatively high proportion, which is also related to the population outflow in Shandong in recent years.

　　Among the 13 cities in Jiangsu, the second largest economic province, 10 cities have been deeply aging. Among them, Nantong, Taizhou, Yangzhou and other central Jiangsu areas are the most aging. Niu Fengrui, a researcher at the Center for Urban Development and Environment Research of China Academy of Social Sciences, told the First Financial Reporter that the degree of aging in Yancheng and other places in central Jiangsu and northern Jiangsu is relatively high, which is related to the strict implementation of family planning and the high proportion of only children in the past. In addition, many young people in this area also flow to Shanghai, Suzhou and other places, so the degree of aging is increasing.

　　Ding Changfa, an associate professor in the Department of Economics of Xiamen University, analyzed the First Financial Report. Jiangsu and Zhejiang have always been economically developed areas in China, especially Jiangsu, which has earlier urbanization, higher living standards and great changes in the concept of childbearing.

　　Tang Hairu, deputy director of the Expert Committee of Hangzhou Planning Commission, analyzed CBN, and from the general law of economic development, the more developed the economy, the more obvious the declining birthrate. On the one hand, personal energy is limited, and I hope to put more energy into the improvement of living standards; On the other hand, in economically developed areas, the cost of children’s education is also rising.

　　Among the 11 cities in Zhejiang, 6 cities have been deeply aging, mainly in northern Zhejiang and along the coast of Hangzhou Bay. Tang Hairu said that in the past, family planning was strictly implemented in northern Zhejiang and along the coast of Hangzhou Bay, and the birth rate was relatively low, so the proportion of aging was relatively high. However, Wenzhou and Taizhou in the southeast of Zhejiang have relatively strong traditional concepts, relatively higher fertility rates and relatively low aging.

　　In other words, the traditional concept of fertility has a significant impact on the fertility rate and aging degree of a place. Compared with the developed areas in the Yangtze River Delta, the aging degree of Guangdong, Fujian and Wentai areas in the southeast of Zhejiang is relatively low. The data shows that among the 21 cities in Guangdong, only one city, Meizhou, has entered a deep aging. Among the nine cities in Fujian, only Nanping, a mountainous city in northern Fujian, has entered a period of deep aging. Influenced by traditional ideas, these places have a relatively high fertility rate.

　　In addition, including the Pearl River Delta and Fujian coastal areas, there are a large number of migrants flowing in, so the degree of aging is relatively low. For example, the population of Shenzhen aged 65 and over is 565,217, accounting for 3.22%, which is the lowest proportion in the country. In addition, the proportion of Dongguan is only 3.54%, which is the second lowest in the country; The proportion of cities such as Xiamen and Zhongshan is also very low.

Topic: 2008 US Presidential Election

Biden at the age of 10.

At the age of 30, he endured the pain of losing his wife and was sworn in as a senator before his son’s bed.

　　In 1972, Biden celebrated his 30th birthday with his first wife and two sons. Not long after, his wife died in a car accident.

In 1977, Biden and his second wife just met.

Biden took a group photo with his family last Christmas. Biden and his wife now have three children and five grandchildren.

　　To understand Biden, his strength, his tenderness, his integrity and his achievements today, we must first understand the family he grew up in and his special life experience.

　　On November 20, 1942, Biden was born in a middle-class family in Pennsylvania, USA. He was the eldest son of the family, and he also had three younger brothers and one younger sister. At the age of 10, the Biden family moved to Delaware. Biden did not come from a political family. His family was Irish immigrants, and his father was just an ordinary car salesman.

　　Biden’s father is a devout Catholic and has a traditional concept of paying attention to family. This special family and religious background has also influenced Biden’s life, making Biden a person who values family life. Biden recalled that his outlook on life, family and even world were deeply influenced by Catholic ideas. Biden believes that his childhood was deeply influenced by former American President John F. Kennedy, who was also the first Catholic president in American history.

　　Biden stuttered when he was a child. In order to get rid of this bad habit, Biden insisted on reciting long poems in front of the mirror since childhood, which not only made him get rid of the stuttering problem, but also laid the foundation for him to become an excellent political speaker in the future. In high school, Biden was very keen on participating in sports activities. He once said that he was an amateur athlete at that time. Biden said: "Sports is my innate talent, but speech is the result of hard work the day after tomorrow." Biden, who was a child, especially liked playing the flute.

　　Part-time law professor

　　Biden graduated from the University of Delaware in 1965, majoring in history and political science. In 1968, he graduated from the Law School of Syracuse University with a law degree. Biden was qualified as a lawyer in Delaware in 1969. He once worked as a lawyer. At the age of 29, he was elected as a federal senator and embarked on a political path. Since 1991, Biden has been a part-time law professor at the Law School of Widen University in the United States, mainly teaching constitutional courses to graduate students of law school.

　　Biden is a heavyweight in foreign policy. He has served in the Senate for 10 years longer than the experienced Republican presidential candidate John McCain and nearly 30 years longer than Obama. Biden just returned from Georgia on the 18th of this month. He participated in the mediation of the Georgia-Russia conflict at the invitation of President Saakashvili. The conflict between Georgia and Russia makes Americans more inclined to choose a leader who is stronger than international affairs.

　　Car accidents have taken awayHe loves his wife and daughter.

　　Text/Washington, DC Special Reporter Zheng Jialiang Our reporter Li Mingbo

　　Beneath Biden’s strong and optimistic appearance, there is also a painful life experience. More than 20 years ago, just as he was enjoying the spring breeze in politics, a car accident took away his beloved wife and young daughter, and his two sons were seriously injured. Our reporter revealed Biden’s tortuous life track to us through interviews with insiders.

　　In the spring of 1964, Biden found his love while vacationing in the Bahamas. A New York girl, Neglia Hunt, came into his sight. Biden later recalled that he sneaked into the hotel swimming pool just to see her more. "The love between us belongs to love at first sight. I will always remember the first time I saw her. At that time, the sunset that was about to set shone her beautifully."

　　In 1966, although Neglia’s parents objected to Biden’s marriage because of his Catholic background, Biden married Neglia Hunt when he was a sophomore. They have given birth to three children, two sons and a daughter. A few weeks after Biden was successfully elected to the Senate in 1972, his life changed greatly. His wife, Neglia, was in a car accident on the way to bring the Christmas tree home. She and her 1-year-old daughter Naomi were killed in the car accident, and their two sons were also seriously injured in the car accident. Biden was in Washington to deal with government affairs, so he escaped.

　　Biden, who had just embarked on a smooth career, was almost crushed after this heavy blow. Biden, who was hit hard, once intended to quit politics, but he decided to take office in the Senate after being persuaded by his colleagues and friends. At that time, Biden was sworn in as a senator by his son’s hospital bed. Today, Biden still stopped work on December 18, the day of the car accident, to mourn.

　　What is even more touching is that in after the car accident for decades, Biden traveled back and forth between Washington and Delaware by train almost every day to meet his family and take care of his two sons who were injured in car accidents. Now, under Biden’s careful care, his two sons have fully recovered. It was this touching life experience that made him have a strong affinity, and Obama took a fancy to him.

　　Biden later recalled that when he learned the bad news of the car accident, despair, grief and numbness came at the same time, and he even thought he had come to the end of the world. He said: "At that time, I really understood how people feel desperate, and I can understand why some people choose to commit suicide as an irrational behavior. I feel that God is playing a terrible trick on me, and I am really angry. "

　　Biden married his second wife, Jill Jacobs, in 1977 and had a daughter, Ashley. Biden’s eldest son, Bao Biden, was elected as the attorney general of Delaware in 2006. Currently, Bao Biden is the captain of Delaware National Guard. According to the plan, he will go to the front line of Iraq to serve in October this year. Biden’s second son, Hunter, is currently a lawyer and once worked in the US Department of Commerce.

　　Biden himself almost died of illness in February 1988. He was admitted to hospital with a cerebral aneurysm and returned to the Senate seven months later.

　　Youngest in history: elected senator at the age of 29

　　Biden once worked as a lawyer, and later went into politics. Biden was elected as a senator at the age of 29, making him the youngest senator in American history. Biden has more than 30 years of political experience since he was first elected as a member of the National Assembly in 1972, and today he is the chairman of the Senate Foreign Relations Committee.

　　Participated in the general election twice in 1998 and 2008.

　　Biden participated in the Democratic presidential primary in 1988 and promised to "rekindle the idealistic flame of our society". He reluctantly withdrew from the primary election three months later after the media revealed that he had plagiarized a speech by a leader of the British Labor Party.

　　On January 30, 2007, Biden filed with the Federal Election Commission and formally participated in the 2008 US presidential election. But because the competition between Obama and Hillary Clinton soon became the focus, Biden’s presidential campaign ended in failure. On January 4, 2008, Biden failed in the first primary (Iowa) and immediately announced his withdrawal.

　　Achievements in internal affairs: effectively fighting crime

　　Biden is also very active in anti-drug and crime, and put forward the law to control violent crimes. In 1994, the law became law, and it was called Biden Act. According to this law, more than 100,000 policemen took to the streets to patrol, which greatly reduced the occurrence of street criminal cases in the United States. Among them, the content of protecting women from violence is the first legal provision in American history to comprehensively protect women. In order to reduce campus crime, he also advocated legislation to prohibit students from drinking alcohol in school social activities. He is an active advocate of the Democratic Party’s policies in environmental protection, social welfare, agriculture and the protection of small businesses.
