Which one was first identified in 24 solar terms?

China's twenty-four solar terms have always been regarded as a feat of losing the most wisdom, but in the twenty-four solar terms, they are not determined from beginning to end, and each solar term has its own representative significance. Of course, the most definite solar term is also the first solar term discovered. Although many people will find that each of the 24 solar terms is accurate, the earliest solar term is not the first of the 24 solar terms, but the summer solstice. The calculation at that time was also very advanced, and it was not easy to calculate such solar terms in ancient times.

First, the limitation of the instrument is the reason for the determination of solar terms. Although there were some instruments for measuring solar terms and astronomical phenomena in ancient times, we have to admit that the ancient instruments were not as advanced as they are now. Many times, the limitations of the instrument also determine the order of solar terms. Therefore, although the first vernal equinox is among the 24 solar terms, its uniqueness is not very strong. On the day of the summer solstice, due to the uniqueness between the earth and the sun, instruments at that time could accurately measure it, so the summer solstice was the first solar term to be determined.

Second, the existence of solar terms is the most important for farmers. Although most people think that solar terms are not very important now, in ancient times, solar terms were very important to every farmer. After all, every farmer wants to have more harvest. So solar terms were the greatest invention at that time. Nowadays, many people will determine the weather according to the solar terms. Of course, solar terms have a great influence in China, and more and more people will pay attention to the food they didn't know before. ?

In the development of history, more and more people will notice that the wisdom of ancient people cannot be underestimated, which is of course very helpful to today's development. Not only the weather, but also the existence of many things in daily life echoes some ancient things, and more and more people have noticed its significance.
