Dujiang Weirs and Qingchengshan Mountain was granted the name of "World Cultural Heritage" by UNESCO. Dujiang Weirs locates in the middle and upper reaches of Minjiang River with a 57-km distance to Chengdu. Dujiang Weirs, a very famous water resource project in the ancient China, was built over 2200 years ago.

At an earlier time, floods happened frequently along Minjiang River. Libing, the governor of Xichuan, transferred the floods into water resource. In Sichuan province, northwest is higher than southeast. According to this kind of terrain, Libing led people to carry out a water reserve project. They separated the water of Minjiang River by means of building a levee in the middle of the river. The front end of the levee is the "water-dividing mouth", which divides Mingjiang River into two parts, the internal river and the external river. The latter one flows into the Yangtze River and the former into Chengdu plains. In order to avoid more sands from flowing into the internal river, they built a "Feishaya" at the middle of the separation levee allowing the floods and mud and sand flow flowing into the external river automatically, resulting in an active control over the flow of the internal river, thus insuring the irrigation and avoiding the floods.

The building of Dujiang Weirs owes to the intelligence of Chinese people. The labors obtained lots of experiences in terms of the water control through the management of Dujiang Weirs, thus the project can be used in a long term and do more benefits to the local people.

In Dujiang Weirs, the main scenic sites are Fulong temple, Erwang temple and Anlan Bridge and so on.

Literary quotation:

Anlan Bridge

Anlan Bridge, also called Fuqi Bridge, connects the internal river with the external river in length of 500 meters. In the old time, it was called Zhupu Bridge and was destroyed at the end of Ming dynasty. Thereby the ferries were put into use, but it is dangerous for people to go by ferry. In the Jiaxing year of Qing dynasty, He Xiande and his wife, who are teachers of a school, proposed to build a bridge and took more efforts in collecting money. At last, they set up a rope bridge. The local named the bridge "Fuqi Bridge" as a way thanking for their kindness. Thanking for the setting up of the rope bridge, the people could pass safely, so the name of the bridge was set to be "Anlan Bridge".
