What activities are arranged during the Twenty-Four Solar Terms?

How old is it?

Our country is a country dominated by agriculture. The ancients gradually mastered the growth laws of plants in agricultural production and recorded them. These are solar terms songs. In fact, solar terms songs did not appear all at once. They were first used during the Spring and Autumn Period and the Warring States Period.

The confirmed ones are the vernal equinox, autumnal equinox, summer solstice, and winter solstice. During the Han Dynasty, the 24 solar terms songs were complete and have been passed down to this day.
