Historical origin

Beginning of winter is the first solar term in winter, representing the beginning of winter and the beginning of March. Beginning of winter, beginning of spring, Changxia and beginning of autumn are collectively called "four stands", namely, spring planting, summer sowing, autumn harvest and winter storage. Everything germinates in spring, grows in summer, harvests in autumn, and no longer hides in winter. Beginning of winter means that life begins to close, everything enters a state of recuperation, plants wither and insects sleep. For example, Xiao Jingwei said, "Fighting means doing things, for beginning of winter and beginning of winter, and finally collecting everything".

As for the division time of the four seasons, China traditionally takes "Li Si" (beginning of spring, Changchun, beginning of autumn and beginning of winter) among the "24 solar terms" as the beginning of the four seasons, and "Bi Fen" (vernal equinox and autumnal equinox) and "Two Fingers" (summer solstice and winter solstice) as the midpoint of the four seasons, which has obvious astronomical significance.
