Dujinagyan Irrigation Project, the long established water conservation works, is located at Dujingayan City lying in the upper reaches of Minjiang River, which is the longest tributary of Yangtze River. During the Warring States Period (475BC 221BC), Li Bing, a governor of Shu in the Qin State, directed the construction of Dujiangyan Weir. From then on, for more than two thousand years the whole system has been functioning perfectly, serving not only as a flood prevention project but also as an immense source for irrigation of the land around it, as well as a means to facilitate shipping and wood drifting.

Qingcheng Mountain, located on the southwest of Dujiangyan City, is one of the birthplaces of Taoism. It boasts 36 peaks, 8 big caves, 72 lesser caves and 108 scenic spots, as well as 11 taoist monasteries and temples. In 2000, he UNESCO inscribed both Dujiangyan Irrigation System and Qingcheng Mount on the List World Heritage.
