Hui River
Hui River, traditionally known as Huan River or Baohui River, was a major tributary of Huai River in northern China. Currently, it flows into the Huai-Hong New Canal
, a constructed flood-control waterway connecting Huaiyuan and Hongze Lake. The starting point of Hui River is the ancient Honggou Canal, which has a great historical significance because it was the border between territories controlled by Liu Bang and Xiang Yu during the Chu-Han Contention. The river is mainly recharged by rainwater and groundwater. The river is heavily polluted by wastewater from nearby towns.
