Dujiangyan TripMost of the people in the group were a little tired and they chose to stay at Jinza Prime Hotel instead of going on with the program today. There were two sightseeing programs - Dujiangyan and Qingcheng Mountain. Duanjiangyan is located about 60km west of Chengdu. Dujiangyan is an ancient irrigation project in China, built about 2000 years ago. Now it is still in use.
Dujiangyan Irrigation is located in the middle part of Minjiang River, the largest tributary of Yangtze River. During the ancient time, the Minjiang River was prone to the flooding mainly due to the fast running Minjiang River flowing down from its mountain source and entering flat ground. 2200 year ago, the local governor - Li Bing with his son devoted most of their life led the construction of the Dujiangyan irrigation project that smartly controlled the Minjiang River and irrigated the surrounding plains.
The governor didn't use the old way of dam building which was just to stop the floods. Instead he made us of a new method by dividing the water into two channels to tame the Minjiang River; one channel for irrigation and the other channel for headwork. When it is a raining season and too much water in Min river. The headwork works and control the flood. When it is in a dry season, just stop the head work and use the irrigation system only. The project effectively put the flooding waters under control.
