Tongtian River

The three principal headwaters — the Chumaer, Muluwusu, and Akedamu rivers — join to form the Tongtian River, which flows southeast to Zhimenda near the frontier between Qinghai and Sichuan provinces, where it becomes the Jinsha River (Jinsha Jiang).
The Jinsha River is a primary and westernmost tributary of the Yangtze River (Chang Jiang).
The Tongtian River is one of the five large rivers flowing from headwaters on the Qinghai-Tibet Plateau.^[1] Its length is 813 kilometres, draining an area of 138,000 square kilometres. Pilgrims go to the river because it is mythical, but also it is known for its "sutra bridge" and "Gyiana Mani stones."^[2]
