The ancient star constellations did not correspond to the solar terms.

On the other hand, the 24 solar terms cycle is China's own calendar, which is completely obtained from the local astrological observation in China. At the same time, its calculation method is ingeniously coincident with the western calendar and placed in the constellation, which also produces a complete fit in the cycle. The reason why the 24 solar terms are so consistent with the corresponding constellations is that they are based on similar astronomical algorithms, so even if they can't accurately predict the weather phenomena around the world, they can reflect the general trajectory of climate change around the world from all angles. Twenty-four solar terms correspond to twelve constellations:

Aries: Corresponding to the vernal equinox to Grain Rain.

Taurus: Grain Rain to Xiaoman.

Gemini: It is equivalent to the summer solstice.

Cancer: It corresponds to the summer solstice to the great summer heat.

Leo: It corresponds to the heat in summer.

Virgo: It corresponds to the summer heat to the autumnal equinox.

Libra: Corresponding to the autumnal equinox to the first frost.

Scorpio: corresponding to the first frost to the light snow.

Sagittarius: It corresponds to the light snow in winter solstice.

Capricorn: It corresponds to the winter solstice to the great cold.

Aquarius: It corresponds to cold to rain.

Pisces: corresponding to rain to the vernal equinox.
