The solstice in winter is one of the eight festivals in four seasons, and it is considered as a big holiday in winter. In ancient times, there was a saying that the winter solstice was as big as a year. Due to different regions, the customs of winter solstice are different in content or details. In southern China, there are customs of offering sacrifices to ancestors and feasting. In northern China, it is a custom to eat jiaozi from winter to Sunday every year.

On the day of winter solstice, although the sun is low and the days are short, the temperature of winter solstice is not the lowest in meteorology.
