Extended data
The twenty-four solar terms were originally formulated according to the changes of stars. The Big Dipper rotates circularly, and bucket handle rotates around the east, south, west and north, which is called one of the "years old" (Figure). Each rotation cycle begins in early spring and ends in severe cold.
The current "twenty-four solar terms" are formulated according to the position of the sun on the return to the ecliptic, that is, the annual movement track of the sun is divided into 24 equal parts, each 15 is 1, and each 1 is a solar term, starting in beginning of spring and ending in severe cold. "Twenty-four solar terms" is an important part of the long history and culture of the Chinese nation and embodies the historical and cultural essence of Chinese civilization.
