The origin of light snow solar terms

1, "light snow" is the season that reflects weather phenomena. It is in the second half of the solar calendar 1 1, and in the second half of October of the lunar calendar. There is little snow. There is no snow on the ground. This is the original meaning of the solar term "light snow". The ancient book "Qunfangpu" said: "A light snow is cold, and it will snow." In other words, due to the cold weather, the form of precipitation changed from rain to snow in the "light snow" festival, but at this time, because the ground is not very cold, the number of snows is small and the amount of snow is not large, so it is called light snow. So light snow indicates the beginning time and degree of snowfall. Light snow, like rain and Grain Rain, is a solar term that directly reflects precipitation.
