Dujiangyan is located in the west of Dujiangyan City, Chengdu, Sichuan Province, on the Minjiang River in the west of Chengdu Plain. It was built in the last years of King Zhao of Qin. It is a large-scale water conservancy project organized by Li Bing and his son, the prefect 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. It has been playing the role of flood control and irrigation for more than 2000 years, making Chengdu Plain a land of abundance with frequent floods and droughts and fertile fields thousands of miles away. Up to now, the irrigation area has reached more than 30 counties and cities, with an area of nearly10 million mu. It is the oldest in the world, the only one preserved and still in use. Its characteristic is that there is no dam to divert water, which reflects the diligence, courage and wisdom of the working people in ancient China.
Dujiangyan Scenic Area mainly includes Fulongguan, Erwang Temple, Anlan Cable Bridge, Yuleiguan, Lidui Park, Leiyushan Park, Yunv Mountain, Lingyan Temple, Zhao Pu Temple, Cuiyue Lake and Dujiangyan Water Conservancy Project.
