Visit Dujiangyan.

Hydraulic engineering tour: The Dujiangyan Irrigation System has been in operation for over 2,200 years and is a testament to the wisdom of the ancients in water management.

Qingcheng Mountain tour: Qingcheng Mountain is divided into the front mountain and the back mountain. The front mountain is mainly Taoist culture, with Jianfu Palace, Shangqing Palace, Tianshi Cave and other palaces and temples, as well as Zhipen Gully, Jiangmo Stone and other mythological and legendary attractions. The back mountain is mainly natural scenery, an excellent place for mountain climbing and summer retreats. The streams, waterfalls, cicadas, and birds form a natural oxygen bar.
