China people divide the 365 days of a year into 24 solar terms. What exactly does the solar term mean?

China is one of the four ancient civilizations, and our ancestors calculated 24 solar terms according to farming. There are 365 days in a year, and there are four seasons: spring, summer, autumn and winter. The ancients in China divided each season into six solar terms, and there were * * * 20 solar terms in a year. These 24 solar terms are: beginning of spring, Rain, Sting, Equinox, Qingming and Grain Rain; Long summer, Xiaoman, Mangzhong, Summer Solstice, Xiaoshu, Dashu; Beginning of autumn, Chu Shu, Bailu, Autumnal Equinox, Cold Dew, First Frost; Beginning of winter, light snow, heavy snow. Winter solstice, slight cold, severe cold. The division of the 24 solar terms is the crystallization of the wisdom of our ancestors.

The theory of twenty-four solar terms originated in the Yellow River basin and can be traced back to the Spring and Autumn Period. During the Spring and Autumn Period, people created four solar terms according to the weather changes, namely, midsummer, midsummer, midsummer and midsummer. Later, through the continuous improvement and perfection of predecessors, in the Qin and Han Dynasties, China had completely established the theory of twenty-four solar terms. In order to remember these 24 solar terms fluently, some ancestors even designed the solar terms Song? Spring rain surprises spring and bright valley days, and summer is full of mans and summer heat is connected; Autumn dew, autumn frost, little snow in winter and cold in winter. ? Today, although many people are no longer engaged in farming, primary school students in our country have to learn and recite the Twenty-four solar term song, which should also be a heritage of civilization.

? The 24 solar terms are divided according to the position of the sun on the ecliptic, not exactly according to time. The sun starts from the vernal equinox, and every time it moves forward 15 degrees, it is a solar term. It runs once and returns to the vernal equinox, which is one year, cycle after cycle, year after year. In other words, the earth's 360-degree revolution around the sun is divided into 24 equal parts, which is 24 solar terms. The time of solar terms in the solar calendar is relatively fixed, while in the lunar calendar, the date of solar terms is not fixed. If there is a leap month in a certain year, the date of solar terms will be very different.

Twenty-four solar terms are the scientific heritage created by our ancestors' practice, which has a good guiding role in China's agriculture, especially in the Yellow River basin.
