What to eat on the winter solstice?

Regarding what to eat in winter solstice, people in the north may eat jiaozi, and jiaozi is indispensable during the Chinese New Year holiday, but jiaozi is delicious. The dietary customs in the south from winter solstice are more abundant. Ningbo eats jiaozi on the solstice in winter, which is a custom that my roommate in Ningbo told me when I was in college. Because we don't eat jiaozi on winter solstice in Yiwu, we have other holiday foods. In Yiwu, there is a custom of worshipping ancestors (we locals call it worshipping the squire) and repairing graves, which is also called "adding soil". In China's traditional consciousness, the solstice in winter is the coldest day, and "adding soil" means "covering the grave with a quilt". In addition to ancestor worship, the winter solstice also pays attention to diet. Bring fried tofu, bean skin, red clams, white meat, etc. These sacrifices are all to be taken home after completion, and they are not wasted at all. However, the rural customs in Yiwu are different. On the solstice in winter, some people eat sesame seeds, buckwheat mice (don't be afraid that they are not real mice, but a kind of pasta made of buckwheat noodles, which will be discussed later), mutton and red bean porridge. In the past few years, ancestor worship required burning incense, paper money, clothes, earth and fireworks, but in recent years, Yiwu has banned fireworks and firecrackers, and the scope of paper money is also stipulated. After all, several fires were caused by setting off fireworks or burning paper money every year. It is everyone's responsibility to prevent fire.
