There is the only extant water mill in western Sichuan that does not wash away the ancient water mill - "Chenjia water mill" on Chenjia Island, two kilometers upstream from the mouth of Luxi River along the Jinjiang River. There are 8 barrel trucks beside the Nianqiao, and more than 800 acres of farmland are irrigated. This Shuinian Island is now one of the "Five Islands of the Yellow Dragon".
