What is the meaning of the solar term song in the first half of the year?

The twenty-four solar terms in the first half of the year refer to the dates of the two solar terms in each month in the first half of the year as 6th and 2 1 day respectively.

Twenty-four solar terms refer to twenty-four seasons and climate, which is a supplementary calendar made by China in ancient times to guide farming.

Because the main political, economic, cultural and agricultural centers in China are mostly concentrated in the Central Plains of the Yellow River Basin in history, the 24 solar terms were established on the basis of the climate and phenology in this area.

As early as the Spring and Autumn Period and the Warring States Period, the working people had the concept of Solstice in the South and Solstice in the North. Subsequently, people divided the year into 24 equal parts according to the natural phenomena such as the beginning of the month, the running position in the middle of the month, the weather, the growth of animals and plants, and gave each equal part a proper term, that is, the 24 solar terms.

There are eight solar terms in Lu Chunqiu, including beginning of spring, Spring Equinox, Long Summer, Summer, beginning of autumn, Autumn Equinox, beginning of winter and Winter. These eight solar terms are the most important of the 24 solar terms, indicating the change of seasons and clearly dividing the four seasons of a year.
