Surrounded by Qingcheng Mountain Scenic Area, it is a famous summer resort, including Nanqiao, Zhao Gong and An Lan Bridge. It is also an excellent attraction to attract tourists.

Construction process: In the fifty-first year of Qin Xianggong (256 BC), Li Bing and his son, the prefect of Shu County of Qin State, led the local people and presided over the construction of the famous Dujiangyan water conservancy project, drawing lessons from the previous experience in controlling the source cave water. Dujiangyan's master plan is to divide the Minjiang River into two branches, one of which is introduced into Chengdu Plain, which can not only divert floods and reduce disasters, but also divert water to irrigate farmland and turn harm into benefit. The main works include Yuzui diversion dike, Sha Fei weir spillway and Baojiangkou water intake.

Origin of the name: Regarding the origin of the name Du Jiang, Shu Shui Kao said: "Fu River, a Chengdu River, has two sources, namely Yongjiang River and Liujiang River." Liu Jiang is another name for Jian Jiang. On the Chengdu Plain, the Fuhe River is Yongjiang River and the Nanhe River is Jianjiang River. Their upper reaches are Baitiao River and Zouma River, which are divided into Dujiangyan and Neijiang. "National Records" said: "Du Jiang is the river of Chengdu". Since the Song Dynasty, the whole Dujiangyan water conservancy project has been generally called Dujiangyan, which accurately represents the whole water conservancy project system and has been used ever since.
