What is a purification ceremony?

Purification ceremony is an important part of folk festivals. Its main function is to "purify" people's living space and living environment. What we call "purification" here is in the sense of religion or witchcraft, and its purpose is to drive away evil, disease, plague, bad luck and all unlucky factors. During the Spring Festival, the purification activities mainly include setting off firecrackers, lighting Spring Festival couplets, sticking door gods and hanging peach symbols. People hope that on this special day of the festival, with the help of various purification ceremonies, all kinds of unlucky factors will be removed, so that they can have a good start and enter the next stage cleanly.
