Table 2 Historical Origin of Twenty-four Solar Terms

As early as the Eastern Zhou Dynasty, the Spring and Autumn Period and the Warring States Period, the concepts of the southern solstice and the northern solstice had existed among our people. Subsequently, people divided the year into 24 equal parts according to the natural phenomena such as the running position of the sun and the moon at the beginning and the middle of the month, the weather and the growth of animals and plants. And gave each equal part a proper name, which is the twenty-four solar terms. By the end of the Warring States Period, there were eight names of solar terms: beginning of spring, Equinox, long summer, Summer Solstice, beginning of autumn, Equinox, beginning of winter and Winter Solstice. These eight solar terms are the most important of the 24 solar terms. Mark the change of seasons and clearly divide the four seasons of the year. By the Qin and Han Dynasties, the 24 solar terms had been completely established.

The book Huainanzi has exactly the same name as the modern one. In BC 104, the taichu calendar, which was formulated by et al., officially set the 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms. In ancient times, solar terms were called "qi", and there were two qi every month: the former was called "solar terms" and the latter was called "neutral qi".

Twenty-four solar terms refer to the twenty-four seasons and climate. Twenty-four solar terms are a supplementary calendar established in ancient China to guide farming, and are the crystallization of long-term experience and wisdom of working people in ancient China. It was formed during the Spring and Autumn Period and the Warring States Period.

Because the lunar calendar in China is a kind of "Yin-Yang calendar", that is, it is based on the sun and the moon's movement, so it can't fully reflect the solar cycle. However, China is an agricultural society, and agriculture needs to strictly understand the sun's movement, so farming is completely based on the sun. Therefore, "Twenty-four solar terms" which separately reflect the sun's movement cycle are added to the calendar as the criteria for determining leap months. Twenty-four solar terms can reflect the changes of seasons, guide agricultural activities and affect the food, clothing, housing and transportation of thousands of families. The 24 solar terms are divided according to the position of the sun on the ecliptic (that is, the orbit of the earth around the sun).

Four seasons correspond to twenty-four solar terms.

In spring, the rain in beginning of spring is startled, and the vernal equinox is clear. In summer, Grain Rain is full of awns in long summer. In summer, it is summer solstice. In autumn, it is summer in beginning of autumn. In autumn, it is white dew. In autumn, it is cold dew in first frost. In winter, it is light snow in beginning of winter. In winter, it is winter solstice.

Spring rains shock spring and clear valley days, and summer is full of mountains and summer heat.

Autumn is exposed, autumn is cold and frost, and winter snow is small and winter is cold.
