Yin is my first name. I only have a first name but no surname. Surnames belong to mortals. People in the underworld, whether they are going to be reincarnated or to be punished, after passing through Huangquan Road and drinking Mengpo soup, they will be cut off from the world, and will lose their surnames and leave only their first names. He would forget all associations with that last name. There is no heaven or hell in this world, only hell. The underworld is a transit station. Every soul must come to the underworld after ending its previous life. The soul can choose to continue reincarnation and experience the next life, or choose to stay in the underworld. Each soul can only have one memory. If you want to choose reincarnation, you must delete the memory of the previous life, drink Meng Po soup, and be reincarnated. Those who do not want to be reincarnated can choose to stay in the underworld, but of course they must work in the underworld. I am one of them, and my job is to lead the way. My duty is to leave the soul at the end of this life and lead him to the underworld. But not any soul can do this job. He must delete the memory of his previous life and must not have any tired love for the mortal world!
