With the development of social economy and the acceleration of urbanization, the problem of air pollution has become increasingly serious, and air pollution has become one of the important factors restricting China's economic and social development. It not only affects people's health, but also causes great damage to the ecological environment. Facing the severe air pollution situation, the state has formulated a series of air quality improvement plans, aiming at creating a clean and healthy living environment for the people and promoting the formation of a green development mode and lifestyle.

　　In recent years, the government of China has attached great importance to environmental protection, incorporated the construction of ecological civilization into the overall layout of "Five in One", and clearly set the goal of building a beautiful China in 2035. Among them, "winning the blue sky defense war" is the top priority in the battle against pollution. To this end, the central government issued the "Three-year Action Plan to Win the Blue Sky Defence War", proposing that by 2020, the proportion of days with excellent air quality in cities at prefecture level and above will reach more than 80%; Specific indicators such as the total emission of sulfur dioxide and nitrogen oxides decreased by more than 15% compared with 2015. At the same time, local governments have formulated stricter air quality standards, intensified the rectification of industrial pollution sources, strengthened the control of motor vehicle exhaust, and promoted the transformation and upgrading of coal-fired boilers, so as to achieve continuous improvement in air quality.

　　The progress of science and technology has also provided strong support for solving air pollution. On the one hand, new energy vehicles are gradually popularized, reducing the pollutant emissions brought by traditional fuel vehicles; On the other hand, the application of intelligent monitoring technology enables environmental pollution to be found in time and effectively controlled. In addition, the concept of environmental protection in internet plus is deeply rooted in people's hearts, and more and more people begin to pay attention to the environmental conditions around them, and actively participate in environmental protection to jointly safeguard their beautiful homes.

　　Air pollution control is a long-term and arduous task, which requires the joint efforts of the government, enterprises and all sectors of society. We believe that with the joint efforts of the whole society, China's air quality will be fundamentally improved, people's quality of life will be significantly improved, and the vision of a beautiful China will be realized as soon as possible! Let's walk hand in hand and leave a blue sky for future generations!
