Menshen or door gods are divine guardians of doors and gates in Chinese folk religions, used to protect against evil influences or to encourage the entrance of positive ones.
Door Gods
门神 (mén shén)
Chinese folk religion includes various types of gods, as well as revered historical figures (either real or legendary.)
One type is Door Gods.
As the name implies, paintings of these gods are pasted onto the main door of a home. The main entrance traditionally consists of two doors, so the gods always appear in pairs.
Although these decorations are not as popular in modern times, some regions of China still do this to bring peace and fortune into the household.
