Tuhai River has a long history and has experienced many vicissitudes. It was formed by dredging and merging Shang River and Tu River which were formed successively in ancient times. On the other hand, at that time, because Dayu used a lot of labor to manage the river, and because wild boars were densely covered in forests on both sides of the river, civilian workers were injured from time to time, and all his disciples were afraid of wild boars, so he was named a violent man.
