Just like a person's bedroom, as the saying goes, who lives in what house is certain. Some houses will be fine if people live in them, but it will be miserable if people live in them. There are other houses where no one can live. That's why. The dead are different from the living. What the living want is the survival aura they need to live, while the dead need a unique five-element aura in order to practice.

Examples of facts abound, so I won't say much.
