Compared with other theories, The Book of Changes has a more subtle sense of time and space. It not only integrates with heaven and man, but also emphasizes the three talents of heaven, earth and man, because heaven is the universe and man is a part of the universe, including all things in heaven and earth. We should explore the nature of life from the understanding of the essential laws of the life universe. The maintenance and guidance of the essence of life can not be separated from the basic logic of the twenty-four solar terms. For example, if we plant a potted flower, you should first judge whether the flower is suitable for any season and whether it needs enough sunshine, and then decide when to water and fertilize it. When you fully understand the essence of temporal and spatial logic of this potted flower, you can take good care of this potted flower, which is also true for human health.

The corresponding logic of twenty-four solar terms and Yijing health preservation;

Spring health should nourish the liver; Spring is the season of hair growth, and the climate is changeable. The meridians, qi and blood of the human body run separately from the liver and gallbladder.

Summer health should be nourished; Summer is the season when the sun is the most abundant, and everything is full of vitality. Chinese medicine believes that latent diseases are easy to occur in summer and autumn, and are more serious in winter, which is called "heart disease".

Keeping in good health in autumn should nourish the lungs: in autumn, the main body converges, the yang gradually loses, the yin begins to breed, the lung qi begins to work, the climate is dry, and it is easy to get thirsty. Therefore, autumn health care should prevent dryness and heat.

Keeping in good health in winter should nourish the kidney; In winter, when everything is blocked by stagnant water, it is necessary to further seal up and nourish Yin. In winter, the five elements belong to water and kidney.

From the evolution of spring, summer, autumn and winter, we can know that the growth and aging of all things change with the growth and gathering of yang, just like trees and people in nature. Therefore, Huangdi Neijing said: "Nourishing yang in spring and summer, nourishing yin in autumn and winter" is a way to adapt to the changes of natural seasons. As the saying goes, "eat radish in winter and ginger in summer" and "drink herbal tea in spring and summer and warm up in autumn and winter" are also ways to conform to the four seasons of Yin and Yang. Besides conforming to the time sequence of the four seasons, keeping in good health also emphasizes the concept of keeping in good health in four seasons in one day:

The Four Seasons Evolution Logic of "Morning is like spring, day is like summer, dusk is like autumn, and night is like winter"

Studies have shown that the life span of mammals is 5-6 times of the growth cycle, and the growth cycle of human body is about 25 years. The theory of life span should be 125~ 150 years. However, at all times and in all countries, most of them will die after half a year, and those who live over 100 years old are as few as the morning star. Therefore, the way to preserve one's health the day after tomorrow is extremely important, and the way to preserve one's health the day after tomorrow is closely related to the laws of seasonal climate. In addition, the internal organs of the human body correspond to the qi of the four seasons, and the yin and yang of qi and blood regularly flow into the twelve meridians at twelve o'clock a day. Therefore, only by adapting to the changes of the four seasons and the twenty-four solar terms and arranging diet and daily life reasonably can we maintain the body of nature in a natural way.

Therefore, although the twenty-four solar terms are symbols of seasonal climate, they not only guide farmers' production, but more importantly, the influence of each solar term on the human body, which is one of the foundations for maintaining good health. Therefore, solar terms are related to everyone (from the emperor to the common people), and each time dimension puts strict requirements on the life and people in it.
