Summer heat, white dew and light snow, which first frost does not belong to autumn?

"Light Snow" is a festival that reflects weather phenomena. There is little snow, and there is no snow on the ground. This is the original meaning of the solar term "light snow". The ancient book "Qunfangpu" says: "Light snow will snow when it is cold, and it will not even snow on the ground, and the snow is not big." 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.

The north wind is blowing and snowflakes are floating, and the area north of the Yellow River has reached Mengdong. At this time, the first snow will appear in northern China. Although the amount of snow is limited, it reminds us that it is the season to keep out the cold and keep warm. Before and after the light snow solar terms, the weather is often cold and gloomy, and people's mood will also be affected by it, especially those friends who suffer from depression are more likely to aggravate their illness.
