The 24 solar terms are: beginning of spring, rain, fright, vernal equinox, Qingming, Grain Rain, Changxia, Xiaoman, Miscanthus, Summer Solstice, Slight Summer, Great Summer, beginning of autumn, Early Summer, White Dew, Autumn Equinox, Cold Dew, Early Frost, beginning of winter, Light Snow, Heavy Snow, Winter Solstice, Slight Cold.

As the saying goes, "A nonstandard name is a bad word", and China people are very cautious about choosing names. How much does it cost to name the year? That's even more cautious. Every name of the 24 solar terms has full consideration and origin.

Beginning of spring, Changchun, beginning of autumn and beginning of winter are the first, seventh, thirteenth and nineteenth solar terms respectively. The four solar terms are divided into four equal parts, averaging one year. Each copy is a season, spring, summer, autumn and winter. "Li" means "establishment", which reflects the beginning of each season.

The vernal equinox, autumnal equinox, summer solstice and winter solstice are divided from the astronomical point of view, reflecting the turning point of the height change of the sun seen on the earth. As we all know, the sun does not always shine vertically on the equator of the earth. The highest point of the sun moves back and forth between the Tropic of Cancer and Tropic of Capricorn. The sun shines directly on the Tropic of Cancer, and China's northern hemisphere is "summer solstice", which means "the most summer". "Want" means the most, such as "supreme" and "strong". On this day, the northern hemisphere has the longest day and the shortest night. Later, the direct point of the sun gradually moved south, and when it reached the direct equator, it was the "autumnal equinox", and the northern hemisphere entered autumn. When the sun continues to move southward and hits the tropic of Capricorn, the northern hemisphere means "winter solstice"-"winter", with the longest night and the shortest day. Since then, the sun has gradually moved northward, and when it hits the equator, the northern hemisphere is the "vernal equinox". The weather is getting hotter and hotter, and the days are getting longer and longer. It's like this all year round.

"Slight summer", "great summer", "summer heat", "slight cold" and "great cold" reflect the change of temperature. "Summer heat" means heat, and "place" means stop. "Small summer heat" is a small summer heat, "great summer heat" is a great summer heat, and "great summer heat" is not hot; A slight cold is a slight cold, and a great cold is a great cold.

Rain, Grain Rain, light snow and heavy snow reflect the time and intensity of rainfall and snowfall. "Rain", there is more rain. "Grain Rain", when it rains, millet is growing; "light snow", it began to snow; "Heavy snow", it snows heavily.

"White dew", "cold dew" and "first frost" mean that the temperature drops and the water vapor in the air is condensing. "White dew", dew began to appear; "Cold dew", dew is cold; The first frost is not dew, but frost.

Scare and Qingming reflect the changes of animals and environment in nature. "Ding", the spring thunder sounded and awakened the hibernating animals. Zheé means animals hibernate. "Qingming", everything in nature is clean and bright, and the whole nature is refreshed.

"Xiaoman" and "Mangzhong" reflect the maturity of crops. "Xiaoman", the barley and wheat fruits in the Yellow River valley began to be full, but not yet mature. The awn seed means that the wheat with awn is ripe, and the rice with awn should be planted first.

Twenty-four solar terms are allocated to 12 month of the lunar calendar, and each month has two solar terms, which add up to such a song: "beginning of spring in the first month, rain in February, vernal equinox, Qingming in March, Grain Rain, long summer in April, xiaoman, Miscanthus in May, summer solstice in June, summer in June, summer in beginning of autumn in July, summer in August and autumn equinox. In the first half of the year, the two solar terms of each month are around the sixth and twenty-first days of the month, and in the second half, around the eighth and twenty-third days of the month. The difference between before and after is at most one or two days. This is the complete "Twenty-four solar term song": "Spring rains startle spring and clear valleys, and summer is full of heat. Autumn dew, autumn frost, little snow in winter and cold in winter. The dates of the two festivals are fixed every month, with a maximum difference of one or two days. The first half of the year is Saturday, 2 1, and the second half is August 23rd. "
