Introduction to Dinghu Bay: Originally known as "Dinghu", "Historical Records·Fengchan Book" records that "The Yellow Emperor collected copper from Shou Mountain and cast a tripod at the foot of Jingshan Mountain. When the tripod was completed, there was a dragon hanging from its beard, coming down to welcome the Yellow Emperor, who rode up. , there were more than seventy people from the harem of the ministers... The rest of the ministers were not allowed to go up, but they all held the dragon's beard, and the dragon's beard was pulled down and fell into the Yellow Emperor's bow... Therefore, later generations named the place Ding Lake. " "Kuo Di Zhi". " said, "The water of the lake originates from Kuafu Mountain, thirty-five miles south of Hucheng County, Guozhou, and flows into the river in the north, which is Dinghu Lake." Emperor Wu of the Han Dynasty built Dinghu Palace here and visited it many times to treat illnesses.
