what is the source of two china's great rivers
Yangtze The river originates from several tributaries in the eastern part of the Tibetan Plateau, two of which are commonly referred to as the "source". Traditionally, the Chinese government has recognized the source as the Tuotuo tributary at the base of a glacier lying on the west of Geladandong Mountain in the Tanggula Mountains. This source is found at 33°25′44″N 91°10′57″E﻿ / ﻿33.42889°N 91.18250°E﻿ / 33.42889; 91.18250 and while not the furthest source of the Yangtze, it is the highest source at 5,342 m (17,526 ft) above sea level. The true source of the Yangtze, hydrologically the longest river distance from the sea, is at Jari Hill at the head of the Dam Qu tributary, approximately 325 km (202 mi) southeast of Geladandong.[49] This source was only discovered in the late 20th century and lies in wetlands at 32°36′14″N 94°30′44″E﻿ / ﻿32.60389°N 94.51222°E﻿ / 32.60389; 94.51222 and 5,170 m (16,960 ft) above sea level just southeast of Chadan Township in Zadoi County, Yushu Prefecture, Qinghai.[50] As the historical spiritual source of the Yangtze, the Geladandong source is still commonly referred to as the source of the Yangtze since the discovery of the Jari Hill source.[49]
