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.

On the solstice in winter, the sun shines directly on the Tropic of Cancer, but on the solstice in summer, it is just the opposite. The sun shines directly on the Tropic of Cancer (the Tropic of Cancer passes through China, from west to east: Yunnan, Guangxi, Guangdong and Taiwan), which is what the ancients said: "The sun is north, the sun is long and the shadow is short, so it is called 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.
