The Three Rivers refer to the Yangtze River, the Yellow River and the Lancang River.

1. Yangtze River The Yangtze River originates from the southwest side of the Geladandong Peak of the Tanggula Mountains on the Qinghai-Tibet Plateau, the "Roof of the World", and is the mother river of the Chinese nation. The main stream flows through 11 provinces, autonomous regions and municipalities, including Qinghai, Tibet, Sichuan, Yunnan, Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and Shanghai, and flows into the East China Sea east of Chongming Island. It is 6,397 km long, more than 900 km longer than the Yellow River (5,464 km). It ranks third in the world in terms of the length of the world's major rivers, second only to the Nile River in Africa and the Amazon River in South America.

2. Yellow River The northern source of the Yellow River originates from Zhaqu at the southern foot of the Chahasila Mountain, a branch of the Bayankala Mountains on the Qinghai-Tibet Plateau in Qinghai Province. The southern source originates from Kariqu at the northern foot of the Gezigeya Mountain, a branch of the Bayankala Mountains. The western source originates from Yugu Zongliequ to the west of Xingxiu Lake. It is in the shape of a "几" character, flowing from west to east through nine provinces (autonomous regions) including Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong, and finally flows into the Bohai Sea.

3. Lancang River The Lancang River is the name of the upper reaches of the Mekong River in China. In Tibetan, Lachu means "Zhangzi River". It is also one of the major rivers in southwest China, the seventh longest river in the world, the third longest river in Asia, and the longest river in Southeast Asia.
