The winter solstice is one of the traditional festivals in China, and it is also an important solar term among the 24 solar terms. Every year on the ninth or tenth day of November of the lunar calendar, when the sun reaches 270 degrees of the yellow meridian, it is the winter solstice. On the winter solstice, the days in the northern hemisphere are the shortest and the nights are the longest. The southern hemisphere, on the other hand, has the longest day and the shortest night, which is caused by the inclination angle between the earth's orbit and the ecliptic plane. After the winter solstice, the sunshine gradually increased and the days gradually became longer, marking the arrival of spring.

In China, the winter solstice is a very important festival. People will eat traditional food such as glutinous rice balls and jiaozi, which means reunion and warmth. At the same time, some places will hold sacrificial activities to pray for peace and prosperity in the coming year.
