Legend has it that the psychic Baoyu is a stone that is not used in "The Goddess of Heaven". After the cultivation of Nu Wa, the stone has become spiritual. Because it is useless, it feels useless, so it is ashamed. Once when he was out, he heard two immortals talking about the life experience of the waiter in Shen Ying, and begged himself to sit next to the waiter in Shen Ying. The two immortals could not bear to beg, so they agreed.

Baoyu is a waiter in Shen Ying. When he was born, the psychic Baoyu in his mouth was the stone left behind.
