The Mar Qu, Ulan Moron (Mongolian: ᠤᠯᠠᠭᠠᠨᠮᠥᠷᠡᠨ, Ulaan Mörön, lit. "Red River"; pinyin: Wūlánmùlún) or Tuotuo River (Tibetan: ཐོག་ཐོག་ཆུ་, ZYPY: Togtog Qu, Chinese沱沱河, p Tuótuó Hé, lit. "Tearful River"[1][4]) is a 336 km (209 mi) long river, located in Qinghai province in the People's Republic of China. Although the Dangqu (or Dam Chu) 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 originally described the Yellow River and the Yangtze. In modern practice, a jiang is usually a longer river, while he varies from shorter rivers (as the Tuotuo) to creeks (such as Suzhou Creek in Shanghai).

  4. ^ But note Mei Zuyan who claims the Chinese name merely transliterates a former Tibetan name.[2] Bolstering his point is the alternate Chinese spelling of the river's name as the 托托. In fact, if the name was originally a transliteration, it probably derives from a variant of the Mongolian Togtoh.[3]
