Flowing from the Qinghai-Tibet Plateau and Hengduan Mountains, the clear and pure snow water goes through the torrential Jinsha River to the upper reaches of Yangtze River, into the abundant water cycle of Luzhou. There are 76 rivers and streams distributed over Luzhou, including Yangtze River, Tuo River, Chishui River and Yongning River which provide pure, sweet and clean water with appropriate hardness.
