Ulan Moron
The Mar Qu, Ulan Moron or Tuotuo River is a river in Qinghai province in the People's Republic of China. Although the Dangqu is the geographic source of the Yangtze River, the Ulan Moron has been traditionally regarded as the main river. With its location in Inner Asia, it therefore belongs to the East China Sea watershed basin.
It begins as melt-off from the Geladandong glaciers and runs to a confluence with the Dangqu, where they form the Tongtian River.
In Chinese, the character 河 originally described the Yellow River and 江 the Yangtze. In modern practice, a jiang is usually a longer river, while he varies from shorter rivers to creeks.
