According to legend, in the Yao-Shun era more than 4,000 years ago, the Yellow River Basin in China suffered a series of disastrous floods. "The soup was cut by the flood, and Hu Aishan Xiangling was swaying, majestic and strange." The whole country was plunged into an unprecedented disaster. Tang Yao presided over a tribal alliance meeting to study the flood problem. At that time, they unanimously recommended Gun, the leader of Xia nationality with a tradition of water control, to preside over Hanshui River. The gun uses the method of "blocking obstacles" to build dams to contain floods. However, the floods are so severe that the dams built are often washed away by floods.

In fifty-one years (256 BC), Zhao Xiang was appointed as the Governor of Shu County, and presided over the construction of the world-famous Dujiangyan water conservancy project on the Minjiang River in guanxian, Sichuan, which effectively promoted the development of local agricultural production.

Jingjiang levee

Jingjiang levee was built in the first year of Yonghe in the Eastern Jin Dynasty (345) and was presided over by Huan Zun, the secretariat of Jingzhou. It was called Jindi at that time. During the Kaiping period of Hou Liang in the Five Dynasties (907 ~ 9 1 1), Jiangling Cunjin Dike was built downstream of Jindi in the Eastern Jin Dynasty. In the Northern Song Dynasty, Zheng Yi, the governor of Jingzhou, presided over the construction of Shashi levee; In the Southern Song Dynasty, Huangtan levee was built, and an inch gold levee was built. After the expansion and repair in Song Dynasty, Jingjiang levee has begun to take shape.

In the twenty-first year of Jiajing in the Ming Dynasty (1542), Haodong on the north bank of Jingjiang River was blocked, which made the dike section from Jintai to Maobuchang 124 km into a whole, which was called Wancheng dike in history and later Wancheng. During the reign of Qing Qianlong and Daoguang, Cunjin levee was connected and extended with Shashi levee. 19 18, Wancheng levee was renamed Jingjiang levee.

History records Shilu very briefly, only knowing that he was ordered to preside over the construction of the famous Lingqu Project in Anxian County, Guangxi, thus connecting the Yangtze River water with the Pearl River water system every time, which played an important role in the reunification of the motherland and the economic and cultural exchanges between the North and the South. The ingenious planning and superb construction technology of Lingqu are still praised by Chinese and foreign people.
