Panyang River is a tributary of the Hongshui River section of the Xijiang River in the Pearl River system. It has two sources, one originating from the Shangpojiao of Wenlijie in Lindong Township, Fengshan County, and the other originating from Laheitun, Dangli Village, Xinxing Township, Tiane County. It flows through Fengshan County, Bama County, and Dahua County, and merges into the Yantan Reservoir, a reservoir of the Hongshui River main stream, in Yixu Township, Dahua County. Because Panyang Village is the middle section, it is named Panyang River. Because Bama County in the basin is the "Longevity Hometown", it is also called the Longevity River. There are many karst mountainous areas in the basin, so many sections of the river are underground rivers. The river section in Bama County has developed tourist areas such as the Bama Panyang River Scenic Area, Cifu Lake, and Baimo Cave.
