On the Significance of Winter Solstice

Winter solstice, also known as short solstice, winter festival, sub-year festival and winter worship, has both natural and humanistic connotations. It is not only an important solar term among the 24 solar terms, but also a traditional folk festival in China.

The winter solstice is one of the eight festivals in four seasons and is considered as a big holiday in winter. In ancient times, there was a saying that the solstice in winter was as big as a year, so the ancients called it off-year or off-year.

The custom of winter solstice varies from region to region in content or detail.

In some areas along the southern coast of China, there are customs of offering sacrifices to ancestors and enjoying the winter solstice. In northern China, it is a custom to eat jiaozi from winter to Sunday every year.
