What's the difference between gods, immortals, demons, ghosts and monsters in China's myths and legends?

The difference between god, fairy, demon, demon, ghost and monster, especially the difference between god and fairy, will inevitably fall into the old question of which level is higher between god and fairy. In fact, that is to confuse the level of official position with the perfection of practice. The problem with the immortal level is that they have different degrees of perfection and different ways to achieve positive results. One is sanctified in the flesh, and the other is soaring after death. Immortals are indeed higher than gods and perfection. But it has nothing to do with the so-called official positions, such as the Northern Emperor, Mount Taishan Tianqi Renshengdi and other gods, all of which have high ranks, far higher than ordinary immortals, what's more, ordinary immortals have not held public office!
