Taking the "River Chief System" as the starting point, Xuzhou Tongshan makes the rivers and lakes "green".

Liguo Town, located on the bank of Weishan Lake, has been dominated by the steel industry for many years. Some iron and steel and mechanical processing enterprises reclaimed and occupied them on their own, causing chaos. In 2019, in the list of rectification of the "Four Chaos" in Weishan Lake assigned by the Ministry of Water Resources, 8 Liguo Township were included in the rectification.

In the face of complicated situations and a large number of historical problems, the Tongshan District Hechang Office took the attitude of opening roads in the mountains and building bridges in the mountains, and quickly came up with a "one enterprise, one policy" plan to accurately solve the problem: for ground structures that should be demolished in the reserve Complete demolition, clean up all the landfills, and restore the original appearance of the lake and beach; for companies that stop production and close down, the Tongshan District government organizes relevant departments and the Liguo Town government to demolish and remove the ground structures on the land; for the projects under construction of transformation and upgrading enterprises, Coordinate and help companies re-select sites for construction, complete demolition and garbage removal after completion and put into operation, and restore the original appearance of the lake and beach.

The water source of Xiaoyanhe River is a river-type surface water source. The upstream water source is the lower lake of Nansi Lake. It is an important surface water source in Xuzhou City and carries the task of supplying drinking water in Xuzhou City. In order to ensure the safety of the water quality of the water source of the Xiaoyan River, the Tongshan District implemented the return of fishing to the lake for 12,200 acres of fish ponds within a range of 1,000 meters on both sides of the Xiaoyan River. The retirement work was completed in mid-November.

"In order to return the Weishan Lake and Xiaoyan River to the original green, the government of Tongshan District has to spend 600 million yuan to compensate the farmers in the lake area for the work of returning fishing to the lake, but the determination of Tongshan to green development is extremely firm." Zheng Yijun said that while returning fishing to the lake, Tongshan District has also completely banned 1,722 livestock and poultry farms of various types within 100 meters on both sides of the tributary of the Xiaoyan River section. Since 2020, the area of key lakes in the entire region has been surrounded by nets. To achieve negative growth, "the "greenness" of Nansi Lake and Xiaoyanhe gradually returned."

The active promotion of "River Chang" has led to rapid progress in the construction of beautiful and happy rivers and lakes. Zheng Yijun said: “Based on the principle of easy first and difficult later, this year, Tongshan District will invest 10 million yuan to promote the construction of 23 beautiful and happy rivers and lakes, including the Chu River, Kui River, Zhengji River, and Langhe.
