Is this the original intention of the author of the 24 solar terms Song Dynasty?

The original intention of writing solar terms and songs is: simple and easy to remember, more convenient to read and understand.

1 and 24 solar terms are separated by about half a month, which is divided into twelve months. It can be seen from the naming of the twenty-four solar terms that the division of solar terms fully considers the changes of natural phenomena such as seasons, climate and phenology.

2. Twenty-four solar terms can reflect the changes of seasons, guide farming activities, and affect the food, clothing, housing and transportation of thousands of households.

3. Xiaoman and Mang in Section 24 reflect the maturity and harvest of related crops; Frightening and Qingming reflect natural phenological phenomena, especially stinging, which indicates that spring will return with the recovery of early thunder in the sky and underground stinging insects.

4. Twenty-four solar terms reflect the apparent movement of the sun in one year, so the dates of solar terms are basically fixed in the current Gregorian calendar, with the first half of the year being 6th and 2 1, and the second half being 8th and 23rd, with a difference of 1 ~ 2 days.
