There may be two reasons why the Chinese hold celebrations on this day. One, is that after a hard working year, farmers always take a rest to enjoy their bountiful harvest. The second reason has to do with the theory of Yin and Yang. In Chinese philosophy, Yin symbolizes the feminine and negative qualities of the universe while Yang the masculine and positive. It is dialectical and dynamic in a sense. When something has reached one extreme, it will turn to the oposite. On the day of the Winter Solstice, the Yin is at its peak with the longest night. From then on, it will give way to the light and warmth of Yang. And the Chinese consider it a right time for optimism and joy.

It used to be a grandiose ceremony for rulers in ancient history. The emperor would worship heaven and ancestors with the court officials' companion and troops stationed around. Colorful flags would flap stiffly in the north wind. The sound of pipes and drums would echo in the brightly decorated streets.

To the common people, the Winter Solstice meant a happy get-together. They would put on their best clothes, visit friends and celebrate it late into the longest night. Food plays an important part in the festivities. But the custom varies from place to place. In the chilly northen part, people eat mutton and dog meat, which are able to bring warmth to the body and dispel the cold. Noodles are popular in the inland areas, while Tangyuan, a kind of stuffed dumpling made of glutinous rice and served in soup, is widely liked in the southen part.

Since the pace of living has become faster and people are now busier, some customs have fallen into oblivion. But quite a few have been handed down also, such as the old 'cold dispelling' song. Before the translation is presented, something has to be made clear. From the Winter Solstice to the spring are a total of 81 days, which are divided into nine nine-day periods. And the day of the Winter Solstice marks the beginning of the first period. Here is the 'cold dispelling' song.

The first and second 'nine days' are so cold
That we dare not hold out our hands,
Stray cats and dogs freeze to death
During the third and fourth 'nine days,'
The fifth and sixth 'nine days' see a thin veil of green
On the far bank of the river,
The rivers thaw during the seventh 'nine days,'
The eighth 'nine days' welcome the wild geese back,
Winter finally draws to an end in the last 'nine days,'
When bright blossoms and flowers smile in warm spring.

Since people have to stay indoors in the freezing cold weather, many kinds of entertainment have been invented to help pass the time. One is painting to welcome spring. On the Winter Solstice, people hang an unfinished painting on the wall, which contains a plum tree and 81 uncolored flowers. Everyday a flower is painted red and when the whole work is done, the bright blossoms indoors will meet the early bursting buds outside the window. Another activity is calligraphy which offers the same result. People write a line of an old poem on a vertically hung scroll, which means the weeping willow in the courtyard treasures the valuable spring time the most. In Chinese, it contains nine characters and each with nine strokes. The elderly will tell the children to write one stroke everyday. It has proven effective to teach them words and to train their patience at the same time.
