What are the couplets of the 24 solar terms?

The winter solstice is cold, first frost eaves, only snow, white dew everywhere;

On the solstice of summer, I was stunned by the pavilions. I hope it will be sunny and Wan Li all day in the slight cold and severe cold.

This couplet contains all the 24 solar terms, and all the solar terms can be found in the couplet, which can be described as a masterpiece.

Twenty-four solar terms, a supplementary calendar established in the pre-Qin period and completely established in the Han Dynasty, is a knowledge system formed by observing the movement of the sun in a year and understanding the changing laws of the four seasons, climate and phenology in a year.

It divides the sun's annual trajectory into 24 equal parts, and each equal part is a solar term, which starts from the beginning of spring and ends in the great cold, and goes on and on again. It is not only a time standard promulgated by successive governments.

It is also a compass to guide agricultural production, a compass for people to predict cold, warm, snow and rain in their daily lives, and a crystallization of the long-term experience and wisdom of the working people of the Han nationality.
