The Yangtze River or Chang Jiang (Simplified Chinese: 长江; Traditional Chinese: 長江; pinyin: Cháng Jiāng) listen (help·info) is the longest river in Asia and the third longest in the world after the Nile in Africa and the Amazon in South America.
The river is about 6,211 km long (3,859 mi) and flows from its source in Qinghai Province in western China, eastwards into the East China Sea. It has traditionally been considered a dividing point between northern and southern China, although geographers consider the Qinling-Huai River line to be the official line of geographical division.
