The origin, characteristics and customs of light snow solar terms

Light snow, in the twenty-four solar terms, indicates the beginning time and degree of snowfall. Entering the light snow solar term means that the temperature continues to fall, the weather is cold, and the precipitation state changes from rain to snow. Light snow, like solar terms such as rain and Grain Rain, is a solar term reflecting precipitation, which is different from what we call light snow with less snowfall every day. If the white dew, cold dew and first frost in the previous solar terms were condensed into water droplets and developed into frost due to the drop in temperature, then the light snow was condensed into snow when the cold dropped below zero. From the change of the names of solar terms, we can see the law of ancient people's activities-observing destiny and arranging life and farming with the change of solar terms. The meaning of light snow solar term "light snow" is a festival that reflects weather phenomena.
