Lao Tzu said

In Dadongdu, the Bai family of Dongling has produced child prodigies from generation to generation. Because of the murder of others, they all ended up beheaded.Because of the protection of others, the two child prodigies left by Dong Lingbai's family were imprisoned... After a prison escape, they met a real person, and with the arrival of the person, the broken memories were pieced together again.
