Religion is a cultural phenomenon in the development of human society to a certain historical stage, which belongs to a special social ideology. The main religions in the world today are Taoism, Christianity, Islam, Shinto, Buddhism, Judaism, Hinduism, Shamanism and so on.

In ancient times, due to the exploration of the unknown universe and the pursuit of expressing people's desire for eternal liberation, people believed that there were supernatural mysterious forces or entities outside the real world, which made people revere and worship this mystery, thus extending the system of belief cognition and ritual activities. Like folk myths, they also have their own myths and legends, which are connected in series with each other, and their essence is a kind of spiritual sustenance and ultimate care.
