After attending the intensive study, Yu Guodong, a member of the National Committee of the Chinese People's Political Consultative Conference, rushed to Beijing for a meeting. When he returned to the office on the morning of the 20th, the first thing he did was to sort out the committee proposals to be submitted this year. "I want to mention a lot, but we must ensure the high quality of the content. I am ready to polish it again," Yu Guodong said. Yu Guodong is also the director of Chongqing Ecological Environment Bureau. How to coordinate the relationship between their work and the performance of their duties? "We will combine the members' performance of their duties with their own work, record the problems found in the research and work, and investigate and improve the problems that need to be paid attention to at the national level at the appropriate time, and finally form the members' proposals." Strengthening the protection of the ecological environment and helping the green transformation of the development mode are closely related to Yu Guodong's own work, which is also the focus of his participation in politics. In 2018, Yu Guodong noticed in his research that some heavy metal pollution standards in soil management need to be revised in time. "Soil is the material basis for human survival, and is an indispensable and valuable resource, but the relevant national systems and regulations were not perfect at that time." So, in the first year of his duties, he put forward proposals to strengthen soil pollution prevention and control, accelerate the improvement of soil environmental quality standards, which were valued and adopted by the Ministry of Ecological Environment, the Ministry of Agriculture and Rural Affairs and other relevant departments. Soon, the Ministry of Ecology and Environment issued the Standard for Soil Environmental Quality and Soil Pollution Risk Control of Agricultural Land (Trial) and other standards. In August of the same year, the Standing Committee of the National People's Congress deliberated and passed the Law of the People's Republic of China on the Prevention and Control of Soil Pollution, and China's soil pollution prevention and control work entered a new stage. "I feel that the country attaches so much importance to the proposal of the committee members, and I am encouraged to cherish this heavy mission even more," Yu Guodong said. With the deepening of his duties, Yu Guodong continued to pay attention to the deep problems involving soil pollution. For example, the situation of soil pollution is not detailed enough, the utilization rate of green and sustainable soil pollution treatment and remediation technology is low, and there are too many enterprises on some contaminated plots, which makes it difficult to identify and blame the responsible subjects. On the basis of in-depth research, he submitted the Proposal on Further Strengthening the Prevention and Remediation of Soil Pollution last year to promote the country to continue to carry out the investigation of soil pollution status of typical industrial enterprises and surrounding areas, and implement the prevention and control of heavy metal pollution sources such as cadmium in agricultural land soil. This proposal was also rated as a good proposal of the CPPCC in 2022. During his five years as a member of the 13th CPPCC National Committee, Yu Guodong submitted 46 proposals in total. Among them, a number of proposals on improving the ecological compensation mechanism of the Yangtze River Economic Belt, stabilizing the use direction of the Three Gorges support fund, and promoting the inter-provincial ecological environment compensation mechanism at the central level have been highly valued and promptly replied by relevant national ministries and commissions, and some of the proposals have been adopted and implemented. "When performing their duties, the committee members should carefully study the national strategic deployment and work priorities, understand the spirit, be full of the smell of soil, and conduct in-depth research at the grass-roots level, so as to understand the actual situation of the ecological environment, find out what is wrong with mountains, rivers and rivers, find the best path to green development, and then make more targeted suggestions and suggestions." Yu Guodong summed up his experience in performing his duties. After being re-elected as a member of the new National Committee of the Chinese People's Political Consultative Conference (CPPCC), Yu Guodong mainly focused on "waste-free cities" when performing his duties this year
