Origin of the Festival
The Winter Solstice Festival, which comes on December 22nd or December 23rd, is also called "Winter Festival". According to the traditional Chinese lunar calendar, one year can be divided into 24 solar terms, and the Winter Solstice is one. Since China is located in the Northern Hemisphere and the sun shines directly on Tropic of Capricorn on that day, the day of the Northern Hemisphere is the shortest all the year around on this day. Then the sun moves towards the Tropic of Cancer gradually after, the daytime of China being longer and longer. Therefore, the Winter Solstice is one of the most important solar terms. After this festival, the "yang" (阳 yáng), a term of the principle in nature, will start slowly picked up.
In ancient China, the Winter Festival was a grand day. In Zhou Dynasty, great ceremony to offer sacrifice to heaven would be held, when the Winter Festival was the same as the New Year. It was until Wudi Emperor of Han Dynasty adopted the traditional Chinese calendar that the New Year’s Day was separated from the Winter Festival. While before that, the emperors, officials and ordinary people even dropped their works to celebrate this day solemnly!
As a folk custom, the reaching time of this festival is a good way to predict the weather of the next year. In terms of folk saying, the days at the end of the year will become cold if the Winter Solstice comes at the beginning of a month; the days of next January will become cold if the Winter Solstice comes at the end of a month; and it will be snowless and frostless if the Winter Solstice comes in the middle of a month (in lunar calendar).
Nvwa and Dumplings
It was said there was a woman called Nvwa (女娲 Nǚwā) jiǎo zǐ with human head and snake body when Pangu created the world. Seeing there was a large hollow in the sky, she mended it by colored stones. And she also made the human beings by earth. When the cold Winter Solstice came, the ears of the human beings were always froze off. So she made a hole in their ears and threaded a line across the ears to the mouths. And the human beings can prevented the falling of the ears by biting this line. People today eat dumplings (with the shape of ears) during Winter Festival. They bite the stuffing (which is of the same pronunciation as the line in Chinese) to spend this day.
Many districts of China eat dumplings on Winter Solstice Festival and some places eat wontons (馄饨 hún tún).
People in Guangxi usually have steamed beancurd buns.
