In Huyang Town, water from Shuanggangkeng, Yuzhuxi, Taomeikeng, Jinxi, Jiefuxi and Wulingkeng enters Dongping Town, turns to Nabina Shangbanxi in the southeast, then turns to the southwest, and joins Taoxi under Waibinawai Mountain Stream and Dongguan Bridge.

Taoxi is named after the sandy beach in the stream contains pyrite and mica flakes. The ancients mistakenly thought it was sand, so it was named after panning for gold in the stream. Grass is everywhere on both sides of Taoxi River.
