Song formula of twenty-four solar terms

The Song formula of the 24 solar terms is as follows:

The spring rain shakes the spring and clears the valley, and the summer is full of mountains and summers. Autumn dew, autumn frost, little snow in winter and cold in winter.

The plum blossoms in the early spring are particularly bright, and the apricot blossoms after the rain are particularly fresh; Lulin thunder, butterfly dance between flowers at the vernal equinox.

When the kite was broken in Qingming Festival, Grain Rain was accompanied by tender tea and emerald, with long summer mulberry fruits like cherries, and a small man who cultivated silkworms.

Before mango seedlings enter the palace, the summer solstice rice and flowers are like white practice; Summer breeze urges early-maturing beans, and Chi Pan enjoys red lotus in hot summer.

Beginning of autumn knows how to make people fall asleep, and sunflowers smile in summer. The white dew returns to the geese, and the autumn equinox smells like osmanthus.

Cold dew vegetable seedlings are green, and the first frost reed flowers are floating all over the sky; Beginning of winter reported good news, reported three rewards, and light snow and goose feathers flew in pieces.

The snow is very cold, the plum blossoms are crazy in the wind, and the winter solstice is full of snow. Little cold wanderers are homesick, and they celebrate reunion at the end of the cold year.

Namely, beginning of spring, rainy, creeping, vernal equinox, Qingming, Grain Rain, Changxia, Xiaoman, Mangzhong, Summer Solstice, Xiaoshu, Dashu, beginning of autumn, Chushu, Bailu, Autumnal Equinox, Cold Dew, Chufrost, beginning of winter, light snow, heavy snow, winter solstice, slight cold and severe cold.

The twenty-four solar terms are divided according to the position of the earth on the ecliptic (that is, the earth's orbit around the sun). Depending on the sun starting from the vernal equinox (longitude zero, at this moment the sun shines vertically on the equator), every advance of 15 degrees is a solar term; After a week's operation, I returned to the vernal equinox, which is a tropical year with 360 degrees, so it is divided into 24 solar terms.
