About Hong
The Red River or the Hong River (traditional Chinese: 紅河; simplified Chinese: 红河; pinyin: Hóng Hé; Vietnamese: Sông Hồng; Chữ Nôm: 瀧紅), also known as the Sông Cái (lit. "Main River"; Chữ Nôm: 瀧丐) in Vietnamese and the Yuan River (元江, Yuán Jiāng) in Chinese, is a 1,149-kilometer (714 mi)-long river that flows from Yunnan in Southwest China through northern Vietnam to the Gulf of Tonkin. According to C. Michael Hogan, the associated Red River Fault was instrumental in forming the entire South China Sea at least as early as 37 million years before present. The name red and southern position in China are associated in traditional cardinal directions. The river is relatively shallow, and carries a lot of reddish silt along its way, appearing red brown in colour.

Geography
The Red River begins in China's Yunnan province in the mountains south of Dali. Main headstreams Leqiu River, Xi River and Juli River confluence at Nanjian where they form the Lishe River. The Lishe River meets with another headstream, the Yijie River at Hongtupo, Chuxiong Prefecture. The river is commonly known as the Yuan (元江) until it reaches Honghe Prefecture. It flows generally southeastward, passing through Yi and Dai ethnic minority areas before leaving China through Yunnan's Honghe Autonomous Prefecture. It enters Vietnam at Lào Cai province and forms a portion of the international border between China and Vietnam.
