Beginning of winter and winter solstice have the habit of eating jiaozi, but there is a saying that only people in some areas are used to eating jiaozi when they are in beginning of winter. The custom of eating jiaozi in winter solstice is handed down in memory of Zhang Zhongjing, a medical sage, because he made a soup to dispel cold and charming ears during the winter solstice and put it in a shed to treat people's frozen ears.

2. In fact, beginning of winter has the habit of eating jiaozi from winter solstice, but there is a saying that only people in some areas are used to eating jiaozi when they are in beginning of winter, and most people are still used to eating jiaozi from winter solstice.

The custom of eating jiaozi on the solstice in winter has a long history, which was handed down by people to commemorate the medical sage Zhang Zhongjing. I will remember Zhang Zhongjing because when he retired in his later years, he saw many people in his hometown's ears frozen.

4. So Zhang Zhongjing made jiaozi's predecessor, Quhan Joule Soup, and applied it in a shed to treat these villagers. Therefore, people drink cold Joule soup from the solstice of winter until New Year's Eve, so that their ears will be fine.
