Wujiang River has two sources, Sancha River in the south and Liuchong River in the north. Sanchahe River originates from the eastern foot of Wumeng Mountain in the western plateau of Guizhou, and flows out from Shigang Cave in Yingdong Village, Yancang Town, Weining County. Springs spew out, springs spew out, streams melt, flow out of the valley, pass through the dam, bypass the Xiangshan Mountain, then connect with a stream, flow southeast through Shuicheng, Nayong, Zhijin and Liuzhi, turn northeast through Anshun, Pingba and Qingzhen, and join Liuchong River. At the confluence, there is a stone pillar rising from the ground, shaped like a bamboo shoot or like a sword barrel. It is called Tianzhu Peak, also called Zhu Ziyan. There is a flat beach under the rock, and there are people on the beach, called Fangji, where the Miao people live together.
Both of them come from the confluence of building foundation and hydrate, forming Yachi River. The river runs through Shandong, splitting the natural barrier of the canyon. There is a dam of Dongfeng Power Station on the river, which divides the river into two sections, and the high gorge flows out of Pinghu. Next to Dongfeng Power Station is Yachi River Old Street, where He Long, Xiao Ke and Wang Zhen led the Red Second Army to cross the river to fight against Japan in 1935.
