The winter solstice misbehaves the jiaozi bowl, and nobody cares if you freeze your ears. Proverbs say: On October 1st, when the winter solstice comes, every family eats dumplings. This custom is said to have been left in memory of Zhang Zhongjing, a medical saint, who gave up medicine on the winter solstice. Therefore, in the north of China, on the day of the winter solstice of the lunar calendar, jiaozi becomes an essential holiday meal, regardless of the rich or the poor.

When the winter solstice comes, eat jiaozi and be round and round. In some places, on the day of the winter solstice, the family will be busy, preparing all kinds of dumpling wrappers and stuffing, and then the family will sit together to make jiaozi, eat jiaozi and have a reunion for the winter solstice. In addition to eating jiaozi in the north, there is also the custom of eating glutinous rice balls in the south, which means that the circle is full.
