What's your opinion and understanding of the content of the 24 solar terms?

Twenty-four solar terms originated in the Yellow River Basin. As early as the Spring and Autumn Period, the four solar terms were defined as mid-spring, mid-summer, mid-autumn and mid-winter. After continuous improvement and perfection, they were completely established in Qin and Han Dynasties. In BC 104, the astronomical position of the twenty-four solar terms was officially determined in taichu calendar written by Deng Ping.

The time when the sun moves along the longitude of the Yellow River from zero to 15 degrees is called "a solar term". It runs at 360 degrees every year, and * * * experiences 24 solar terms twice a month. Among them, the first solar term of each month is "one solar term", namely, beginning of spring, Jingzhe, Qingming, Changxia, Mangzhong, Xiaoshu, beginning of autumn and Zhong Bai. The second solar term of each month is "Zhongqi", that is, there are 12 solar terms such as rain, vernal equinox, Grain Rain, Xiaoman, summer solstice, summer heat, summer heat, autumn equinox, first frost, light snow, winter solstice and great cold. "Solar term" and "neutral qi" appear alternately, each lasting 15 days. Now people

In order to facilitate memory, people compiled 24 solar terms songs:
