Chuanjiang Haozi is a folk singing form in which boatmen lead the singing and other boatmen join in the singing to unify the movements and rhythm. Chongqing and eastern Sichuan are the main birthplaces and inheritance places of Chuanjiang Haozi. Chuanjiang Haozi is mainly spread in the Jinsha River, Yangtze River and its tributaries Minjiang River, Tuojiang River, Jialing River, Wujiang River and Daning River.
