Chazhen Liangzi is 4,345 meters above sea level, the top of the hilly plateau in the southern part of Hongyuan, and there is a source of water in the north of the mountain, which is called the Somkouqu (Tibetan meaning "Tongguo River"), and flows south into the Dadu River tributary Suomo River, which is the upper tributary of the Yangtze River. The Gaqu River (Baihe) is a famous dragon day song in the south of the mountain. The process is 400 kilometers. It is injected into the Yellow River near the Soke Tibetan Monastery in Tangke Township, Ruoergai County. Therefore, Chazhen Liangzi and the Yellow River watershed of the Yangtze River are called a great spectacle.
