Extended data:

The current "24 solar terms" take the earth's revolution around the sun as a cycle, which basically summarizes the different positions of the sun on the ecliptic at different times of the year, the exact time when cold comes and summer goes, and the laws of some natural phenomena such as phenology in nature.

Twenty-four solar terms are 24 time points, and when the "point" falls is the natural result of celestial movement. All the year round begins with "four stops", and the so-called "stop" is the beginning. Beginning of spring, Changxia, beginning of autumn and beginning of winter represent the beginning and arrival of spring, summer, autumn and winter respectively.

In order to express the characteristics of time series more accurately, the ancients divided the solar terms into four groups according to the weather and phenology: divided, arrived, opened and closed. "Fen" means vernal equinox and autumnal equinox, which was called "dichotomy" in ancient times; "Solstice" is the summer solstice and the winter solstice, which was called "the second solstice" in ancient times. "Qi" refers to beginning of spring and Changxia, "Closed" refers to beginning of autumn and beginning of winter, and beginning of spring, Changxia, beginning of autumn and beginning of winter are collectively called "Sili", which add up to * * * to "eight sections".

Folk call it "four seasons and eight festivals" or "eight festivals a year" If you choose the key points in the eight sections, it is the "second solstice" of the summer solstice and the winter solstice. On the solstice in winter, the sun shines directly on the Tropic of Cancer, while on the solstice in summer, it is just the opposite. The sun shines directly on the Tropic of Cancer, which is what the ancients said: "The sun reaches the north with a long day and a short shadow, so it is called the summer solstice." Do your best.

The naming of the twenty-four solar terms reflects three seasons, phenology and climate changes. The solar terms reflecting the changes of the four seasons are: beginning of spring, Spring Equinox, Long Summer, Summer Solstice, beginning of autumn, Autumn Equinox, beginning of winter and Winter Solstice. Among them, beginning of spring, Changxia, beginning of autumn and beginning of winter are collectively called "Sili", which means the beginning of the four seasons.

There are five solar terms reflecting temperature changes: slight summer heat, great summer heat, summer heat, slight cold and severe cold. There are seven solar terms reflecting weather phenomena: rain, Grain Rain, white dew, cold dew, first frost, light snow and heavy snow. There are four solar terms reflecting phenological phenomena: Jing Zhe, Qing Ming, Xiaoman and Mang Zi.
