On the fifth day of the first month, commonly known as "Breaking Five", the folk food custom in many places in China is to eat jiaozi. In some places, Bao jiaozi is also commonly known as "pinching a mean person's mouth". When wrapping jiaozi, you should pinch it by hand along the edge of jiaozi. It is said that this can avoid slander.

There is a folk saying: the first day you have sex, the third day you go home, and the fourth day you spread eggs on pancakes. Pinch the mouth of the villain on the fifth day and eat noodles on the seventh day. Therefore, it is a habit to eat jiaozi on the first and fifth day of the first month. Eating jiaozi on the first day of the Spring Festival is to welcome the New Year, which means to say goodbye to the old and welcome the new. Eating on the fifth day of the fifth month carries the meaning that people expect good luck and happiness. Besides, this day is the birthday of the God of Wealth, and setting off firecrackers to eat jiaozi is also a symbol of welcoming and respecting God.
