Origin of the light snow solar term
'light snow' is a festival reflecting weather phenomena. " "Light snow" is in the second half of November of the Gregorian calendar and the second half of October of the lunar calendar. The snow is small and there is no snow on the ground, which is the original meaning of the solar term 'light snow'. The ancient book "Qunfang spectrum" says: "a little snow is cold and will snow. The ground is not cold and even the snow is not big." That is to say, on the 'light snow' Festival, due to the cold weather, the form of precipitation changes from rain to snow, but at this time, due to the 'lack of cold', the snow falls less frequently and the amount of snow is not large, so it is called light snow. Therefore, light snow indicates the starting time and degree of snow. Light snow, like rain, grain rain and other solar terms, is a solar term that directly reflects precipitation.
Meaning of light snow solar term
The ancient book "Qunfang spectrum" says: "a little snow is cold and will snow. The ground is not cold and even the snow is not big."

" The lotus has no rain cover, and the chrysanthemum residue still has frost branches', which is a scene of early winter. Because there are Qinling Mountains and Daba mountain barriers in the north to block the invasion of cold air and weaken the cold wave, the "winter warmth" in South China is significant. The number of snowfall days in the whole year is mostly less than 5 days, much less than that in the middle and lower reaches of the Yangtze River at the same latitude. There is little chance of snow before heavy snow. Because the temperature near the ground layer in South China is often maintained above 0 ℃ in winter, snow is not easy than snow. However, in the cold Northwest Plateau, it usually begins to snow in October. The annual snowfall days in the northwest of the plateau can reach more than 60 days, and some alpine areas may have snowfall all all year round.
