The origin and custom of light snow

The origin of the light snow solar term: Light snow, one of the 24 solar terms, the sun reached 240 degrees in the longitude of the Yellow River, and the climate in China began to get cold at the earliest. In many areas, it reached 0 degrees and began to snow. However, at the beginning of the weather, Leng Xue was small, so it was called Xiaoxue. The customs of Xiaoxue solar terms are: eating Ciba, pickled vegetables, drying dried fish, making soup and eating mutton.

The story of the origin of light snow solar terms was first seen in the twenty-four solar terms in Yuan Dynasty, that is, fifteen days after beginning of winter, and bucket handle called the sea light snow. It rained in the middle of October (lunar calendar) and was cold and thin, so it condensed into snow. Small words are not prosperous. "1in the middle of October, the rain was about to fall but was invaded by cold air, so it solidified into snow.

The ancient book "Qunfangpu" also said: "Light snow is cold but it will snow, and the ground is not even cold but the snow is not heavy." Light snow solar terms, the climate in most areas began to get cold, but the temperature in general areas is around zero, and the snowfall is not large, which is reflected in light snow, so it is called light snow.
