It passes through many places and gathers into the 80-square-kilometer source of Longjiao—Gaoxia Pinghu. . In 1970, a dam was built to collect water and the Longyuan Reservoir was built. The words "Gaoxia Chu Pinghu" on the dam are imitated in Mao Zedong's handwriting, with each character 16 meters in diameter. There are scenic spots such as Lake Center Island, Sanjing, Lianxin Island, Chunmeng Island, Dishui Rock and other attractions in the lake.
