Auspicious Snow Sealing the Earth: The Nascent Yang within Supreme Yin at the Major Snow Solar Term
This article offers a deep reading of Major Snow (Daxue) among the twenty-four solar terms, drawing upon pre-Qin Confucian and Daoist philosophy, etymological origins, astronomy, and phenology. It analyzes the etymology of 'da means flourishing — at this point snow flourishes,' examines the Hexagram of Return (Fu) with its 'single yang returning' in the zi month, and reveals the virtue of auspicious snow sealing and protecting nascent yang, along with the profound cosmology of 'supreme yin birthing yang — the heart of Heaven and Earth.'

Chapter Fourteen: Major Snow in the Book of Songs and in Literature — "The Falling Snow, Thick and Fast" and the Realm of Snow Poetry
I. "The Falling Snow, Thick and Fast": Snow and the Human Heart in the Book of Songs
Snow is one of the most ancient and moving images in Chinese literature. Its headwaters lie in the Book of Songs.
The final stanza of "Cai Wei" ("Gathering Vetch") in the Lesser Odes is Chinese literature's most celebrated snow-poem across the millennia: "When I set out, the willows were trailing. Now I return, the falling snow is thick and fast. The road is long and slow; I thirst and hunger. My heart aches with sorrow; who knows my grief$10"
"The falling snow, thick and fast" (yu xue fei fei) — these four characters fuse the homeward soldier's vision of all-encompassing snowfall with the boundless ache within his heart. Here, snow is not merely a natural scene but a mirror of the human heart — its ceaseless, swirling fall reflects the soldier's inner turmoil and sorrow; its limitless expanse mirrors his grief without end. This is one of the wellsprings of the Chinese literary tradition of "scene and feeling merged as one."
II. Multiple Resonances of Snow in the Book of Songs
Snow in the Book of Songs is rich in associations, far beyond sorrow alone.
In "Xin Nan Shan": snow as nurturing grace and auspicious omen — the "auspiciousness" of snow. In "Cai Wei": snow as the vehicle of sorrow and homesickness — the "melancholy" of snow. In "Bei Feng" ("North Wind"): snow as bitter cold, peril, and the backdrop against which friends join hands to flee calamity — the "cold" and "hardship" of snow.
The auspiciousness, the melancholy, the cold — with plain yet profound strokes, the Book of Songs already sketched out a rich emotional spectrum for the image of snow. Snow, in the pre-Qin ancients' hearts, was no mere weather phenomenon but a cultural symbol bearing rich emotion and deep meaning.
III. Snow's "Purity": The Aesthetic Sublimation of the White Image
Snow's immaculate whiteness symbolizes purity, loftiness, and a spirit unstained by dust. A world blanketed in snow, all filth concealed beneath silver-white, presents a kind of spiritual purification. In later literary tradition, snow is constantly linked with elevated character, transcendent spirit, and pure-hearted integrity.
IV. The Spiritual Underpinning of the Snow-Poetry Tradition: Loftiness Amid Severity, Vitality Within Storage
Surveying the tradition of snow poetry from the Book of Songs onward, its spiritual underpinning resonates profoundly with Major Snow's core philosophy: to discern loftiness amid severity, to perceive vitality within storage.
Snow poetry celebrates snow's "auspiciousness" — seeing nourishment and hope for harvest amid bitter cold; its "purity" — guarding a space of immaculacy amid a soiled world; and its "steadfastness" — enduring in harsh cold, unbowed in adversity (as in the later tradition of the "Three Friends of Winter" — pine, bamboo, and plum, standing proud amid Major Snow's bitter cold as symbols of steadfast, elevated character).
