Currently, it flows into the Huai-Hong New Canal[1] , a constructed flood control waterway connecting Huaiyuan and Hongze Lake.

The starting point of Hui River is the ancient Honggou Canal (鸿沟), 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 (206 - 202 BCE).

The river is heavily polluted by wastewater from nearby towns.
