From ancient times to the present, it is said that there is a spiritual realm in the world.
Regarding the saying of the spiritual realm, celebrities and scholars of all dynasties have different opinions. It is recorded in the poem:
"From Qi to Tang, this mountain is desolate and desolate, the spiritual realm is lonely, and few people visit it."
"The spiritual realm is indescribable, and it is difficult to find ghost work."
