For readers following the traditional Chinese calendar, “Major Snow” (Daxue) carries a sense of gathering momentum. It is the twenty-first solar term and the third of winter’s four chapters, usually arriving around December 6th or 7th. The character “Da” (大) means “great” or “large,” while “Xue” (雪) means “snow.” Together, Daxue signals that cold has intensified and snowfall becomes more frequent and heavier — winter is no longer whispering; it is speaking with growing force.
What Does “Daxue” Mean?
The ancient text Yueling Qishier Hou Jijie explains: “The eleventh month’s節气, snow becomes heavy, hence the name.” In other words, by the time Daxue arrives, temperatures have dropped low enough for snow to fall more regularly and accumulate on the ground. Compared with Minor Snow (Xiaoxue), which marks the first tentative appearance of snow, Daxue represents a deepening of winter’s grip.
That said, “Major Snow” does not mean every region will experience heavy snowfall. In northern China, snow may become a regular visitor. In the south, the temperature may simply plunge further, with snow remaining rare or absent. The solar term functions as a climatic signal — a marker of deepening cold rather than a guarantee of specific weather.
Nature’s Signals: The Three Pentads of Major Snow
Ancient Chinese observers divided Daxue into three five-day periods to capture the quiet but unmistakable transformations of deepening winter:
- First Pentad: The Night Bird (鹖鴠)Does Not Cry. The night bird (hé dàn), a bird associated with cold nights, falls silent. In ancient texts, this bird was said to cry through cold nights, pleading for dawn. When it stops calling, it signals that winter has reached a depth where even the creatures of the cold grow quiet. From a natural perspective, many birds reduce their activity as temperatures drop, conserving energy in shelter.
- Second Pentad: Tigers Begin to Mate. As the deepest cold sets in, tigers begin their mating season. Ancient observers noticed that these solitary predators, usually hidden and elusive, became more active during this period. The appearance of tigers in the records reflects the idea that even in the harshest cold, life continues its cycles.
- Third Pentad: The Litchi Sprouts Appear. Litchi trees begin to show tiny new buds. This may seem surprising in the depth of winter, but it reflects the ancient understanding that within the deepest yin (cold), the first stirrings of yang (warmth) begin to emerge. The litchi, a subtropical tree, responds to subtle shifts in energy, hinting that even in winter’s peak, spring is already being prepared.
Climate Characteristics of Major Snow
The defining feature of Daxue is the intensification of cold and the increased likelihood of snowfall. Across much of China, temperatures continue their downward trend. In the north, daytime temperatures often remain below freezing, and nighttime cold becomes severe. Snowfall becomes more frequent, and snow may begin to accumulate on the ground, creating the white landscapes associated with deep winter.
Cold air masses from Siberia become stronger and more frequent, bringing sharp drops in temperature, strong winds, and sometimes blizzard conditions. In regions such as Northeast China, Inner Mongolia, and Xinjiang, Daxue often coincides with some of the coldest days of the year.
In southern China, while snow may be rare, the damp cold becomes more penetrating. The air feels heavy with moisture, and the chill seems to seep into clothing and bones. This is the season when people begin to rely more heavily on heating, warm clothing, and nourishing foods.
Customs Full of Everyday Warmth
Daxue is not only a climatic turning point but also a time when food, preservation, and community come together to meet the cold.
1. Eating Sweet Potatoes
In some regions, Daxue is associated with eating sweet potatoes. The sweet potato, warm and nourishing, is seen as an ideal food for cold weather. Roasted sweet potatoes, with their caramelized skins and soft, golden flesh, are a common street food during this time, offering both warmth and comfort.
2. Drinking Mutton Soup
In many parts of China, Daxue marks the beginning of “winter nourishment” in earnest. Mutton soup is a popular choice, as lamb is considered warming in traditional Chinese medicine. A steaming bowl of mutton soup, often cooked with ginger, scallions, and herbs, is believed to strengthen the body and ward off the cold.
3. Making Pickles
In some areas, Daxue is a time for making pickled vegetables. The cold weather helps preserve the vegetables while developing a tangy, crisp flavor. Pickled cabbage, radish, and other vegetables become important side dishes during the winter months, adding brightness to otherwise heavy meals.
Conclusion
Major Snow is the moment when winter fully asserts itself. The air grows sharper, the days grow shorter, and the landscape takes on a quieter, more austere beauty. Snow may fall heavily in the north, blanketing fields and rooftops in white. In the south, the cold may be less dramatic but no less real.
Yet Daxue is not only about cold. It is also about preparation — the curing of meat, the making of pickles, the sharing of warm soups. It is about the human response to nature’s deepening chill: to gather, to nourish, to find warmth in food and community.
In the silence of a snow-covered field, in the aroma of curing meat hanging in the cold air, in the steam rising from a bowl of soup, Daxue reveals a truth: winter is not merely an ending. It is also a time of gathering strength, of quiet resilience, and of the promise that even in the deepest cold, life continues.
