What does the word superstition mean? How did it come from?

The word "superstition" is originally a persistent or irrational belief. But in modern times, western learning spread to the east, and people accepted western science and could not understand the culture handed down from their ancestors. They can't understand what is good and what is dross in traditional culture, which is called feudal superstition, especially during the Cultural Revolution. Up to now, the original meaning has not been realized, and the connotation has changed.
