Is it enough for Yin and Yang to buy three in 24 solar terms?

No, 24 solar terms, yin and yang teacher, can't buy three. Twenty-four solar terms refer to twenty-four solar terms, which is an important climate calculation method in the history of China, and can help people determine the date of the lunar calendar. 24 solar terms described the earth's rotation according to the position of the sun. Based on the maximum of the yellow meridian when the sun reaches the earth's surface at the full moon every month, it is calculated that the yellow meridian 15 degrees before and after the full moon every month is a solar term, with a total of 24 solar terms. 24 solar terms's calculation involves the relationship between the position of the sun and time, so buying three is not enough. More historical computer technology is needed to complete 24 solar terms's calculation.
