Twenty-four solar terms.
It is a knowledge system formed by Chinese based on their observations of the sun and the natural world to guide agricultural production and daily life. The system divides the orbit of the earth around the sun into 24 equal parts, each equal part is a solar term, reflecting the laws of climate, phenology, seasonality, astronomy and other changes. Reflecting the changes of the seasons, there are the beginning of spring, the spring equinox, the beginning of summer, the summer solstice, the beginning of autumn, the autumn equinox, the beginning of winter, and the winter solstice; The solar terms that reflect phenology include stinging, Qingming, and Xiaoman.
Miscanthus; Precipitation is reflected in rain, valley rain, and white dew.
cold dew, frost, light snow, heavy snow; The change in temperature is reflected in the light heat.
The big heat, the heat, the small cold, the big cold. As the saying goes, "the heat is in the dog days, and the cold is in the three nines", which means that the third "nine days" after the summer solstice and winter solstice are the hottest and coldest times of the year respectively, appearing in the solar terms of the great heat and the great cold; The 24 solar terms reflect the changes in natural conditions such as temperature, humidity and light required for the growth of crops and other plants, and are the truth of the proverb "there is no fixed law for farming, it all depends on the solar terms" and the idiom "do not violate the agricultural time".
Today, the 24 solar terms occupy a guiding position in agricultural production and daily life, and profoundly affect the thinking and behavior of Chinese, and are the embodiment of traditional Chinese culture.

The current "24 solar terms" are based on a cycle of the earth's revolution around the sun as a reincarnation, which basically summarizes the different positions of the sun on the ecliptic at different times of the year, the exact time of cold and summer, and some phenological phenomena in nature. The 24 solar terms are 24 points in time, and the specific day on which the "point" falls is the natural result of the movement of celestial bodies. The four seasons of the year start from the "four stands", the so-called "stand" is the beginning of the meaning, the reputation of filial piety spring, summer, autumn, winter, respectively, represents the beginning and arrival of spring, summer, autumn and winter.
During the winter solstice, the sun directly hits the Tropic of Capricorn, and the summer solstice is just the opposite, the sun directly hits the Tropic of Cancer (the Tropic of Cancer passes through our country, from west to east is: Yunnan, Guangxi, Guangdong, Taiwan), that is, the ancients called "the north solstice, the length of the day, the shadow of the sun is short, so it is called the summer solstice." The most solitary, the extreme.
The naming of the 24 solar terms reflects three types of seasons: seasonal, phenological phenomena, and climate change.
The solar terms that reflect the changes of the four seasons are: the beginning of spring, the spring equinox, the beginning of summer, the summer solstice, the beginning of autumn and the balance of travel, the autumn equinox, the beginning of winter, and the winter solstice. Among them, the beginning of spring, the beginning of summer, the beginning of autumn, and the beginning of winter are called "four stands", which means the beginning of the four seasons.
There are five solar terms that reflect the temperature change: small heat, big heat, summer heat, small cold, and big cold. Weather phenomena are reflected:
There are 7 solar terms of rain, valley rain, white dew, cold dew, frost fall, light snow, and heavy snow. Reflecting the phenological phenomenon, there are four solar terms: stinging, Qingming, Xiaoman, and miscanthus.

The 24 solar terms are the product of agricultural civilization and have a great impact on people's production and life. More than 2,000 years ago, the Chinese ancestors divided the solar year into 24 periods of basically equal length by observing the annual movement trajectory of the sun and the changing rhythm of the celestial phenology, forming a unique Chinese culture of 24 solar terms. It not only guides the farming activities of ancient Chinese farmers, but also has a new connotation in modern society.
The reason why the 24 solar terms have been able to be passed down for thousands of years and have been believed by people is that the ancient Chinese relied on the land and revered nature, and it has always nourished this beautiful and rich land and the people who work it.
In the modern society with advanced science and technology, people have long ceased to rely on the 24 solar terms, but the long cultural connotation and historical accumulation it contains are still what we need today. The 24 solar terms are the crystallization of the wisdom of the ancient Chinese and an important part of the long history and culture of the Chinese nation. It depicts the most harmonious relationship between nature and man, engraves the common memory of the Chinese nation, and also carries the ardent expectation of hundreds of millions of descendants of Yan and Huang to cherish nature and live in harmony with nature.
For thousands of years, this friendship has not been broken.
