Significance of Hades' Full Text of Visiting Famous Doctors

Bruto sent a ghost pawn to visit a famous doctor in the underworld, saying, "He who has no ghost in front of the door will do it." Ghost soldiers came to Shi Yang on orders, and every time they passed the medical gate, ghosts gathered. Finally, when I arrived at a family, I saw a man sneaking around at the door and said, "These are all famous doctors." When asked, it was yesterday that the new medicine brand was erected.

-"Little Guang Lin, Pluto visits a famous doctor"

This joke is easy to understand, not too profound. In other words, the prince asked the ghost pawn to visit the famous doctor among the dead, and the prince said, "A famous doctor is a man without ghosts in front of his door." The ghost soldier went to Shi Yang after receiving his will. Every time he passes a second light, many ghosts gather. Until they came to the last house, they only saw a ghost hovering at the door of this light. Then the ghost pawn said, it seems that this righteous light is a famous doctor. Then ask him, it turns out that this billion light just opened yesterday.
