What does rebirth mean?

Rebirth is to reincarnate the dragon and become a human being!

Isn't there such a TV series called "Jigong Living Buddha"? It's about Lohan reincarnated as Li Xiuyuan, then Li Xiuyuan became a Taoist priest and a crazy monk, and then he killed demons by his own magic to save the world. Among them, a Ming monk and a fat fairy boy were reincarnated to help Lohan's entourage.

So I think metempsychosis means metempsychosis of the dragon Lohan and becoming a human being!
