"South China Sea Weird Chronicles" contains: "There is a mountain named Fulong a hundred miles west of Xi City in Pinglu. It is named after its shape similar to Fulong Zhenmei. There are two mountain gods, namely Jiaobai and Heikang. Some people wrote on it and climbed Fulong to look for Tiandong. They were surprised to see Jiaobai. They climbed up again in the same year and couldn't find it."
