On the left side of "Hainan's first mountain" carving side, there is a large boat-shaped rock, called the "stone boat", also known as "the fairy boat". Legend has it that since immemorial time, this was where Sea Dragon King moored the boat when he picked Ganoderma in the mountain. Later it was called saint boat mooring. Under the Stone boat, there is bizarre cave, narrow, deep and many twist and turns, known as "36 holes". It is said that the Sea Dragon King heard about the Ganoderma grass can treat diseases, so he took a boat to this place. The Jade Emperor blamed his unauthorized left, so he gave order to withdraw seawater, change his boat into stone boat. When the Sea Dragon King was trapped here, a Dongshan God guided the king leaving from the 36 holes. So people say the 36 holes are connected with Dragon Palace.
