 The Wanquan River (Chinese: 万泉河; pinyin: Wànquán Hé; literally ten-thousand-spring river) is the third longest river in Hainan Province China and is 162 km long. It rises in the Wuzhi Mountain and flows generally northeast turbulently in a narrow route through mountainous regions. About half way downstream it enters Qionghai.
