When did feudal superstition begin to prevail?

Superstition originally refers to people's blind belief or worship of things, such as books, money and so on.

Feudal superstition is a special term established by convention after the liberation of our country, which refers to people's thoughts and behaviors of believing in astrology, divination, witch doctors, geomantic omen, signs of life, ghosts and gods, etc. These things existed in primitive society and slave society, but because they prevailed in feudal society, people called them feudal superstitions. Feudal superstitious activities refer to related activities carried out by gods, witches, fortune tellers and geomancers who cheat money by feudal superstitious thoughts and behaviors, including lottery, divination, fortune telling, divination, inviting gods, exorcising ghosts, seeing geomantic omen and treating diseases with water.
