The simplest twenty-four solar terms jingle.

The simplest jingle of the twenty-four solar terms is: spring rain surprises spring and clear valley days, summer is full and summer is hot; Autumn dew, autumn cold frost, winter snow cold.

Twenty-four solar terms refer to 24 specific festivals in the China lunar calendar, which indicate the changes of seasons. They are formulated according to the position change of the earth on the ecliptic (that is, the orbit of the earth around the sun), and each one corresponds to a certain position reached by the earth every time it moves 15 on the ecliptic.

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.
