It is where the Suzi river and Hun River converge. Du Song was advised to camp for the night, but he refused, and so forded the river topless and clouded with liquor on horseback. He was then asked to wear armour, and he replied that being in the military for this many years he did not know how heavy armour was as he never wore it and crossed the river. When his forces were half way across, Nurhaci ordered his bannermen to break the dams they had prepared, and thus a portion of Du Song's men and equipment had to be left behind or were lost in the river.
