In 2000, Mount Qingcheng and the Dujiangyan Irrigation System were inscribed on the list of World Heritage by UNESCO.
Bothe Mount Qingcheng and the Dujiangyan Irrigation System are situated in the west of Chengdu, Sichuan Province, China. Mount Qingcheng is a renowned mountain as one of the Taoist mountains of Chin. Being the seat of Taoism in history, the evergreen Mount Qingcheng covers an area of over 120 kilometers. In the Eastern Han Dynasty (25-220 AD), the founder of Taoism, Tianshi (Celestial Master) Zhang Daoling once set up his pulpit here to give lectures. During the Tang Dynasty, advocates of the newly introduced Buddhism vied with the Taoists for this base, until Emperor Xuanzong allocated the mountain to the latter.
The Dujiangyan Irrigation System, one of the three irrigation projects, 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. The irrigation system have been working for more 2200 years and still irrigates today. The water is split from the Minjiang River to the West Sichuan Plain. We can say no Sichuan civilization without this irrigation system that turned the agricultural potential of the plain into a land of abundance.
