Historical origin

"The Book of Filial Piety" says: "On the 15th day after (beginning of winter), the bucket pointed to the sea, and it was a light snow. The sky and the earth are overcast, the temperature is rainy, and the cold is snowy. At that time, those who talked less were not cold and the snow was not heavy. " Xiaoxue solar term is a climate concept, which represents the climate characteristics during Xiaoxue solar term. Climate factors include precipitation, temperature and light, among which precipitation is an important factor of climate.

Light snow is a solar term reflecting the changing trend of temperature and precipitation. Meteorology, rain, snow, hail and other water vapor condensation falling from the sky to the ground are called "precipitation". This solar term is called light snow because "snow" is the product of cold weather. During this solar term, the climate is not deep and the precipitation is not great, so "light snow" is used to compare the climate characteristics during this solar term. The arrival of the light snow solar term means that the weather is getting colder and colder and the precipitation is increasing.
