The Winter Solstice, also known as the Short Solstice, Winter Festival, or Asian New Year, is not only one of the 24 solar terms, but also a traditional Chinese folk festival. The ancients believed that the winter solstice is a natural transformation of yin and yang, and is a blessing bestowed by heaven. Therefore, there is a saying that the Winter Solstice is as big as the year itself. The winter solstice customs vary in content or details due to regional differences. In southern China, there is a custom of ancestor worship and feasting during the winter solstice. In northern China, there is a custom of eating dumplings on the winter solstice.
