In the first year Zhenguan (627 CE), Li Ji’s (594-669 CE) beloved daughter died, and she was buried at Bei Mang, with a servant’s cottage built next to the tomb. One day, the daughter suddenly appeared to the servant and said: “I did not die in the first place, but was rather stolen away by the spirit of a great tree. Now, the spirit having left on a pilgrimage to Xiyue, I have therefore managed to run away. I knew that you were here, so I came. I have already been parted from my parents, and returning from this would be humiliating, so I cannot go back. If you hide me, I can reward you with great wealth.” The servant was flabbergasted, but eventually agreed, and built another room for her. The girl sometimes left at dawn to return at dusk, sometimes left at nightfall to return at dawn, her every step like the wind. A month later, she suddenly brought ten jin of gold (about 5 kg) as a gift, and the servant accepted it. When he went to sell it, however, the family who had lost it seized the servant to report the matter. The governor of Luoyang was determined to get to the bottom of the matter, so the servant told the full story. When they followed him to seize her, the girl had already gone, and the remaining gold had all turned into yellow rock. (Taken from the Sunxianglu).
