Built at the end of Zhao Haoqi in Qin Dynasty (about 256 ~ 25 BC1), it was a large-scale water conservancy project organized by Li Bing and his son, the magistrate of Shu County, on the basis of excavating the turtle spirit of their predecessors.

It consists of a fish mouth, a flying sand weir and a treasure bottle mouth. For more than two thousand years, it has been playing the role of flood control and irrigation, making Chengdu Plain a "land of abundance" thousands of miles away.

The establishment of Dujiangyan has its specific historical roots. During the Warring States Period, people suffering from war longed for the early reunification of China. Coincidentally, after Shang Yang's political reform, Qin was once famous all over the world, virtuous and virtuous, and the country became stronger and stronger.

They correctly realized the special strategic position of Bashu in the process of unifying China. Under this historical background, at the end of the Warring States Period, Zhao Haoqi of Qin appointed Li Bing, who was familiar with astronomy and geography and lived in seclusion, as the prefect of Shu County.

After Li Bing came to power, he first made up his mind to eradicate the flood in Minjiang River, develop agriculture in western Sichuan, benefit the Chengdu Plain and create an economic foundation for Qin to unify China.
