Emperor Wu of the Han Dynasty missed Mrs. Li whom he had lost forever. He ordered Li Shaojun and said to him: "I am thinking about Mrs. Li. Can she be seen?" Shaojun said: "It can be seen from a distance, but it is not the same as a curtain. There is a hidden stone in the dark sea. It is green in color and as light as feathers. It is cold. The stone is warm when the heat is high, and the stone is cold when the heat is high. If the stone statue is carved into a human figure, the lady will be able to interpret human speech, so it is known that the spirit is different."
