Is Yan a fairy or a ghost?

It belongs to God. Supposedly, he and the Jade Emperor are on the same level. The jade emperor is in charge of the top and he is in charge of the bottom. But strictly speaking, the jade emperor is still a little older than him, just like the current chairman and general manager.

He is a god who specializes in ghosts. He just hangs out with ghosts all day. Just like prison guards, we can't say that prison guards are prisoners!

The accurate answer is God!
