Name
The Chinese name comes from a fabled river in the classic novel Journey to the West. In antiquity, it was called the Yak River.[clarification needed][citation needed] In Mongolian, this section is known as the Murui-ussu (Муруй-Ус, lit. "Winding Water")[1] and is sometimes confused with the nearby Baishui.[2]
Geography
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 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.[3] Its length is 1,012 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".[clarification needed][4]
