How does the 24 solar terms feel wrong?

Twenty-four solar terms refer to twenty-four seasons and climate, which is a calendar invented by China in ancient times to guide farming. In ancient China, the sundial was measured by earth gauge, and the longest sun shadow was defined as the sun solstice (also called sun solstice, sun solstice and summer solstice), and the shortest sun shadow was defined as the sun solstice (also called short solstice and winter solstice). In the Spring and Autumn Period, there was a day with the same length of day and night, which was defined as vernal equinox and autumnal equinox. There were only four solar terms in the Shang Dynasty, and eight in the Zhou Dynasty until the Western Han Dynasty. The concepts of yin and yang, four seasons, eight places, twelve degrees and twenty-four solar terms are mentioned in the preface to Historical Records.
