Chengdu is the most populous city in the Sichuan basin.  It lies within what is called the "heavenly state" and is the capital of the Sichuan Province . The Sichuan Province is the subject of many Chinese, mythical stories and ancient civilizations. Travelers encounter the heart of these stories at the Dujiangyan Irrigation System.

Dujiangyan Irrigation System is a UNESCO world heritage site that channels the Minjiang River away water from the Chengdu plains. It is the largest tributary fed by the Yangtze River. The powerful Yangtze River frequently flooded early Chengdu settlements. The governor of Shu decided to channel water rather than dam it during the 3rd century BCE. It remains an important source for shipping, farming, and wood drifting.

The heritage site is the home to several religious artifacts, historical monuments, and archaeological parks in addition to being a major technological innovation. Anlan Suspension Bridge, for example, is a local site of great interest.

The 1640 foot long bridge hangs above the two channels. The bridge used to be entirely constructed of bamboo rope. Today it is supported with a steel wire that facilitates a pendular motion when visitors sway on the bridge.

The irrigation system is also close to chain of Taoist temples. Mount Qincheng and its 36 peaks inspired numerous construction projects. The mountain range is the birthplace of Taoism. The Dragon Naming temple is one of the more prominent buildings.
 
The irrigation system is 35 miles west of Chengdu and buses provide access to the park. The bus leaves from the Chengdu railway station. Travelers who do not want to take the bus can participate in a tour group or make other local arrangements through a travel agency.
