As a special festival in the trunk calendar, the twenty-four solar terms indicate the change of natural rhythm and establish the "December construction". It was originally formed on the basis of the movement 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.

During the period of Emperor Wu of the Western Han Dynasty, the "Twenty-four solar terms" were absorbed into the taichu calendar method, and the solar terms were measured in the Yellow River basin by the method of soil return surveying and mapping, as a supplement to the calendar, to guide the farming in the northern part of the Central Plains. In the Yellow River Basin, the day with the longest sun shadow and the shortest day (the shortest day) is the winter solstice, and the winter solstice is the starting point of the "24 solar terms". The winter solstice and the next winter solstice are divided into 24 equal parts, the time between each solar term is equal, and the interval between each solar term is 15 days.
