Pújiāng

Pujiang lies southwest of Chengdu, where the plains give way to the wooded hills approaching Meng Mountain. In 1764 a waterworks called the Dragon Claw Weir was built to draw water from the Mao River into fields on the western side of the county. Its branching channels gave the work its name. The county gazetteer records how the diverted water made it possible to irrigate land that had depended on rain.
