Introduction to Dinghai Zhuang: There is a reef on the sea not far from Tianjing Pavilion, which is called Dinghai Zhuang among the people. According to records, King Feng Jiayi of Nanzhao once had the characters carved on a stone: "The gate of the country is here". This reef is also the stone mule in the folklore of the Bai people "Wangfuyun". Legend has it that a princess of Nanzhao fell in love with a hunter and eloped to Cangshan Mountain. Master Luo Quan used his magic to bring down a blizzard in an attempt to freeze the lovers to death. In order to keep out the cold, the hunter flew to Luoquan Temple to steal the eight-treasure cassock, but was beaten to the bottom of the sea by the mage and turned into a stone mule; the princess's essence turned into a Wangfu Cloud, which often appeared at the top of Cangshan Yuju Peak. At this time, strong winds and waves arose in Erhai Lake, and the princess's lover, a stone mule, appeared from the bottom of the sea. Now this reef has emerged from the water and is used as a navigation mark by boatmen.
