Jiaozi, also known as jiaozi, is deeply loved by the people of China. It is a staple food for people in northern China, a local snack, and also a Chinese New Year food. There is a folk proverb called "freezing in the cold, eating jiaozi in the New Year." Jiaozi often cooks with flour and leather bag stuffing.

The custom of eating jiaozi:

As the saying goes: "It's freezing in the cold, so eat jiaozi in the New Year." China New Year is the biggest festival in China. In order to have a good year, the old farmers began to be busy with the New Year as soon as they entered the threshold of the twelfth lunar month.

Starting from the 23rd day of the twelfth lunar month, commonly known as "off-year", the countdown to the New Year begins, lanterns are decorated, couplets are put up, and the courtyard is cleaned to prepare for a reunion year for distant relatives. In northern China, the most important activity on New Year's Eve is the family's package of jiaozi.

There is a tradition of eating jiaozi on New Year's Eve, but the custom of eating jiaozi varies from place to place. Some places eat jiaozi on New Year's Eve, and some places eat jiaozi on the first day. Eating jiaozi is a unique way for people to express their wishes when they bid farewell to the old and welcome the new.

Jiaozi is homophonic with Jiaozi, that is, when the old year intersects with the new year. Eating jiaozi during the Spring Festival means good luck. Besides, jiaozi is shaped like an ingot, and wrapping jiaozi means good luck.
