The earth turns from west to east, and the old man says that Chengdu is 48 inches lower than Dujiangyan. Therefore, the water in Dujiangyan flows eastward, from high to low, and the speed of water naturally flows quickly. This is a natural law, and people cannot change it. This is our beautiful photo.

Dujiangyan is located on the Minjiang River in the west of Chengdu Plain, Sichuan, 56 kilometers away from Chengdu. It is a large-scale water conservancy project built by Li Bing, the prefect of Shu County in Qin State during the Warring States Period, and it is the oldest existing water conservancy project in China that still irrigates farmland and benefits the people.
