In the East, why are most people buried in the mountains after death, while westerners are buried in the plains in movies? Why is this?

This is called celestial burial. First, it is beneficial to the environment, because the corpse can be used as fertilizer to moisten trees and is also food for carnivores. Second, it is a kind of faith to give your body to the God you believe in. People think this is an honor! This can not only satisfy the belief, but also save some procedures such as cremation and coffin, which is one of the good ways to protect nature.
