Located in southwest Dujiangyan City, Sichuan Province, this site consists of Mt. Qingcheng, the Dujiangyan Irrigation System, the Dragon Stream (Longxi) and the Iris Port (Hongkou). Mt. Qingcheng is one of the birthplaces of the Taoist religion with famous temples such as Shangqing, Tianshi and Jianfu and many historic relics. It was put on the UNESCO World Cultural Heritage List in November, 2000.

The Dujiangyan Irrigation System was first built in 256 BC (during the Warring States Period) by magistrate Li Bing. It comprises three major projects -- a water-dividing dam, flood-convergence route and water-divergence port. As one of the earliest irrigation systems of China and still in use today, it serves to divert waters from the Minjiang River to the West Sichuan Plain. It is a major landmark in the development of water management and technology in ancient China.
