The custom of burning malnutrition festival

In the northwest of China, the 23rd day of the first month is the "Bibi Festival", and there is a folk saying that "every household has Bibi on the 23rd day of the first month every year". In ancient times, people were in great awe of fire, believing that it was pure and could cure all diseases.

Every night, every household in the countryside will light a bonfire at their doorstep, and firewood must be collected from outside, not from home, which means gathering wealth. In addition, people should hold celebrations and cross the flames happily. When they go too far, they should say, "If you burn dry, if you burn clean, if you burn clean, you will never get sick", so as to wish themselves a lifetime.
