Twenty-four solar terms are precious wealth of ancient people in China. For the ancients in agricultural civilization, the invention of this solar term has benefited and helped the ancients for nearly 2000 years, and it is also an important part of our traditional culture. At present, the earliest historical document that we know to record the 24 solar terms is Huainanzi? Astronomical training. Ancient people relied on the 24 solar terms to judge the changes in the operation of heaven and earth, and the 24 solar terms were mainly used in agriculture. Therefore, in the ancient farming civilization society, the invention of this solar term directly promoted the development of farming civilization and the increase of crop yield at that time, which was a very important invention of farmers' life. With the changes and progress of the times, we have now entered the era of industrialization, and the influence of farming culture on modern society is gradually weakening. In agriculture, we can also rely on science and technology to operate the most suitable environment for simulating crops, which is weakened by weather and nature. However, the dependence of crops on science and technology and less on the environment does not mean that the 24 solar terms are useless to modern society. In economically underdeveloped rural areas, many farmers' uncles still plow fields and judge farming and harvest seasons by solar terms.

People can judge and adjust their diet and clothes according to the 24 solar terms. Hard-working and thoughtful people in China attach great importance to diet. For example, the Millennium is suitable for health preservation. At this time, it is necessary to adjust the diet, mainly to moisten the lungs and dryness, because the weather is dry at this time, and it is easy to get angry, and there will be chapped skin and dry stool. The 24 solar terms still have a lot of use value in our life and culture. From the aspect of TCM health preservation, although early autumn and late autumn are in the same season, the climate is completely opposite. Therefore, health care and prevention of corresponding diseases are completely different, and should be based on solar terms. In addition, vernal equinox, summer solstice and autumn solstice still play an important role in modern astronomy, which is beneficial to observe the running time of celestial bodies.
