2. Winter solstice custom: Many places in southern China will celebrate the winter solstice. Some coastal areas in the south continue the traditional custom of ancestor worship. Every household is dedicated to ancestor statues, memorial tablets, etc. Go to the hall at home, place an altar, set up incense burners, offerings, etc. In some places, while offering sacrifices to ancestors, they also offer sacrifices to gods, land gods and deities, so as to make the next year's weather favorable and the family prosperous.

In many parts of northern China, it is a custom to eat jiaozi every winter solstice. According to legend, Zhang Zhongjing, a medical sage, saw a frozen person when he retired in his later years, so he wrapped mutton, some cold-dispelling herbs and dough into the shape of ears, made a medicine called "Quhan Jiaoer Decoction" and gave it to the people. Later, on the solstice of winter, people imitated eating and formed a custom.

3. The concept of winter: Winter, also known as Winter Festival, Asian New Year Festival and Dragon Festival, 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. Winter solstice is regarded as a big holiday in winter. There is a folk saying that winter solstice is as big as a year, so the ancients called it "sub-year" or "off-year".
