It's playing an important role in the flood control and irrigation work for more than 2000 years.

Yuzui Water-cut Dike was built in the center of the river, which divided Minjiang River into the inner river for irrigation and outer river for flood control; Feishayan was used to discharge flood, sand distill and regulating water flow; Baopingkou was used to control water inflow, as its shape looks like a bottle neck, thus the name Baopingkou (Bottle neck in Chinese).

Dujiangyan project made fully use of the geographical advantage of the local conditions like the higher northwest and lower southeast. The dike, water separation, flood discharge, sediment, flow control interdependently, forming a total system to ensure that the full play of flood control, irrigation and the social benefits of the water. Sichuan has great economic and cultural development. The greatness of its huge development is the building of the dam and its benefits brought. Dujiangyan was built in the premises that not destroying the natural resources and making full use of the natural resources to serve the human beings thus turned the waste into the benefits, forming a high degree of harmonization of the people, land and water.

The larger-than-life painted statues of father and son overlook the rushing river below. Nearby a stone tablet os engraved with a famous six-character quotation from Li Bing, "when the river flows in zigzags, cut a straight channel. When the riverbed is wide and shallow, dig it deeper." The temple which is built near the mountaintop is a popular stopping place for sightseers. There one can enjoy a unique view of the most modern parts of the water conservation project.

Hidden Dragon monastery was built inside the Lidui Park; Legend has that Libing used to suppress the evil dragon here, thus the name.
