Extended data:

The current "twenty-four solar terms" come from the "fixed gas method" concluded more than 300 years ago (it has been used since 1645). The current "twenty-four solar terms" are formulated according to the position of the sun on the ecliptic, that is, the annual movement track of the sun is divided into 24 equal parts, and each 1 equal part is 1 equal part.

There are 24 solar terms, each of which represents different changes in climate, phenology and time. In the historical development, the 24 solar terms have been incorporated into the lunar calendar and become an important part of the lunar calendar.
