What is a ghost? What is God?

In the traditional culture of China, ghosts and gods are different biological states. Ghosts are ghosts produced after the death of various creatures, with different powers, often smaller than gods, and even some ghosts are afraid of things like people; God generally refers to the immortal, which is a miraculous state achieved by various creatures through cultivation. In various legends of China, ghosts and gods can't be touched or seen in real life, but they can communicate with them through prayers and sacrifices.
