Why do you eat jiaozi on the solstice in winter?

Jiaozi is eaten to get rid of diseases and drive away cold, and ears are not frozen in severe winter. It is said that this custom was left in memory of Zhang Zhongjing, a "medical sage", who gave up medicine during the winter solstice.

Northerners usually eat jiaozi: in the north of China, jiaozi is definitely eaten on the solstice in winter. In the north, no matter whether poverty intensifies or wealth increases, people will eat jiaozi on this day to celebrate the arrival of the winter solstice. Eating jiaozi on this day also represents family reunion.

Different regions have different views on the method and origin of the winter solstice, which has long been a popular festival, and the date of the winter solstice is roughly the same, even if the time difference is not too long, so the words about the winter solstice are already like the Spring Festival.
