From End to Beginning: The Way of Culmination and Return in the Great Cold Solar Term
This article offers a deep reading of Great Cold (Dahan), the final of the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, etymological analysis, and astronomical and phenological traditions. It reveals the dialectic of extreme cold and returning spring, the cyclic principle that every ending harbors a new beginning, and illuminates the late-winter rites of the Grand Nuo exorcism and the clay ox ceremony—inviting the reader into the ancients' cosmic wisdom of 'tracing origins by returning to endings' and the eternal circle of ceaseless renewal.

Conclusion: The Circle of Great Cold--Meeting New Life at the Endpoint
I. Looking Back: What Have We Learned$21
Through the detailed analysis of the preceding nineteen chapters, we have explored the Great Cold solar term from multiple angles--astronomy, calendrics, phenology, mythology, philosophy, governance, ethics, ritual, folk custom, agriculture, health cultivation, literature, and musical pitches. As the last of the Twenty-Four Solar Terms and the terminal term of the year, Great Cold carries significance far deeper and grander than "the coldest days of the year."
We have learned: the name "Great Cold" signifies "the reverse extreme of cold"--cold qi accumulated to its utmost, while the very words "reverse extreme" imply "when things reach their extreme they must reverse." We have learned: Great Cold is the final link of the Twenty-Four Solar Terms, the terminal term; its "ending" is immediately followed by Start of Spring's "beginning"--when things end, they begin again; the year's end is the mother pregnant with the year's start.
We have learned: beneath Great Cold's coldest surface, yang-qi has long since quietly returned and is secretly growing. The Winter Solstice (weakest yang) passed long ago, the sun long since reversed its course; the Lin hexagram's "two yang gradually growing" shows yang already at the second line; Kan's central yang shows that the deepest yin inherently contains the most vital yang. Great Cold's "yin at its extreme" is precisely "yang born"--extreme cold, returning spring; after the darkest hour, the dawn.
We have learned: Great Cold's three pentads--hens begin to brood (responding to yang-qi, nurturing new life), raptors hunt with fierce swiftness (the extreme of austerity while life strives), ice on lakes and marshes freezes to the core (yin-cold at its extreme while yang is about to flourish)--compose an exquisite miniature epic of "yin at its extreme, yang born," proclaiming new life and hope within the coldest phenological signs.
We have learned: the rites and customs of the final month of winter's Great Cold--the Grand Nuo to see off the cold, clay oxen to welcome spring, La and Zha sacrifices, sweeping dust, preparing for the new year, bidding farewell to old and welcoming new--are humanity's solemn participation in and heartfelt celebration of the Way of Heaven's great cycle of "extreme cold, returning spring" and "when things end, they begin again."
We have also learned: Confucianism faces Great Cold's "ending" with "being as careful at the end as at the beginning" and "year-end self-examination"; Daoism apprehends Great Cold's "reversal" through "reversal is the movement of the Way" and "returning to the root." And both ultimately point to the same core--recognition and emulation of the Way of Heaven's "when things end, they begin again; life ceaselessly renewed."
II. The Circle of Great Cold: A Metaphor
If we compared Start of Summer to a "door" (the threshold from spring's birth to summer's growth), then the most fitting metaphor for Great Cold is a "circle"--an eternally revolving ring where endpoint and starting point coincide.
Great Cold is the seam of this circle. It is the terminus of the year's vital breath--cold's extreme, yin's extreme, storage's extreme, ending's extreme; yet precisely at this terminus, the circle bends around and coincides with the starting point (Start of Spring). Reaching Great Cold, this "terminus," does not mean reaching the road's dead end, hitting a wall; on the contrary, it means completing one revolution and returning to the starting point, ready to set out again.
Standing at Great Cold's seam, we gain a unique vantage--we see both "ending" (looking back over the year's birth, growth, harvest, and storage, watching it reach its limit) and "beginning" (looking forward to the new year's sprouting, watching it gestate at the terminus). Ending and beginning merge before our eyes; past and future converge, interconnect at this single point of Great Cold. This is the realm of "tracing origins by returning to endings"--at the endpoint, one sees the full panorama of the cycle; at the coldest, darkest, most silent extreme, one touches the pulse of the Way of Heaven's "ceaseless renewal of life."
The circle of Great Cold is therefore a metaphor filled with hope. It tells us: there is no true "dead end," for the road is a circle, and reaching its end is reaching a new starting point; there is no eternal "bitter winter," for cold is cyclical, and reaching its extreme is the eve of spring. At every "Great Cold" in life, we stand at a circle's seam--take just one more step, turn just one more corner, and there is new life, there is spring's return.
III. The Final Question: Why Do We Need to Re-understand Great Cold$22
At the essay's close, let us return to the initial question: why do we need to re-understand Great Cold$23
Because in modern life, we have nearly lost our reverence for "ending" and nearly lost our hope for "beginning." We live in climate-controlled rooms, unable to feel Great Cold's bitter cold; our time is cut into endless, uniform, linear fragments, unable to feel the solemn cyclicality of "year's end and year's beginning." We no longer "carefully attend to endings and pursue the distant" or "examine ourselves and sweep away dust" at year's end, nor do we hold "bidding farewell to old, welcoming new" and "extreme cold, returning spring" in our hearts at year's start.
Re-understanding Great Cold is not about returning to the way of life of the pre-Qin era (neither possible nor desirable), but about recovering the wisdom of "cyclical time" and the faith in "ceaseless renewal of life." When Great Cold arrives, try to feel: this is the year's end, the moment for solemnly "attending to endings," for reckoning "self-examination," for cleansing "sweeping dust," for gathering "farewell to the old"; and at the same time, this is the eve of the new year, the moment for holding hope and "welcoming the new," for trusting without doubt that "spring will return." In this convergence of "ending" and "beginning," "storage" and "birth," "cold" and "warmth," you may once again touch the cycling, ceaselessly renewing Way of Heaven that the ancients recognized--and this recognition can offer modern people, amid their restlessness, anxiety, and disorientation, the deepest peace and the firmest hope.
Above all, Great Cold's wisdom is a wisdom about "hope." It tells every person in "winter"--in adversity, at a low point, in a seemingly hopeless place: extreme cold must give way to returning spring, ending must give rise to beginning, in the darkest depths yang-qi is quietly growing (yang within Kan, two yang gradually growing, hens begin to brood). This is not blind optimism, but a steadfast faith grounded in the deepest insight into the Way of Heaven's cyclical law. No matter how bitter life's "Great Cold," so long as one deeply trusts and emulates this Way of Heaven's "ceaseless renewal of life," one can, in the coldest night of winter, keep watch over the spring that must surely come.
IV. Ending and Beginning Again: A Blessing of Ceaseless Renewal
The Master said: "Does Heaven speak$24 The four seasons proceed, the hundred things are born--does Heaven speak$25"--Heaven does not speak, yet through the four seasons' course and the birth of all things, it ceaselessly sends us its message.
Our series set out from Start of Spring's "birth," passed through Start of Summer's "growth"... and now, in Great Cold's "storage," at the "last" of the Twenty-Four Solar Terms, we are about to conclude. But this "conclusion," like Great Cold itself, is by no means a termination--it is "ending giving rise to beginning," the start of a new cycle. Great Cold passes, Start of Spring comes again; this essay concludes, and a new year's "four seasons proceed, the hundred things are born" will begin anew.
This is Great Cold's, the Twenty-Four Solar Terms', the Way of Heaven's most profound blessing to each and every one of us: ending and beginning again; life ceaselessly renewed. May we all, in every "Great Cold" of life, hold firm to "extreme cold, returning spring," recognize "when things end, they begin again," and emulate "ceaseless renewal of life"--being as careful at the end as at the beginning, keeping watch for new life at the point of despair; ceaselessly striving for self-improvement, embarking on a new journey at the year's end.
Heaven does not speak. But in the coldest night of Great Cold, through "hens beginning to brood," through "two yang gradually growing" in hidden stirring, through "east wind thaws the ice" that must follow "ice frozen to the core," it sends us its warmest, most steadfast message--
When cold has reached its utmost, spring is about to return.
When ending has reached its limit, beginning is about to start.
