What does the light snow solar term mean?

1, Xiaoxue is the twentieth of the twenty-four solar terms. Every year on Gregorian calendar1October 22nd or1October 23rd, the sun reaches 240. Light snow indicates the beginning time and degree of snowfall, which directly reflects the precipitation, just like the solar terms such as rain and Grain Rain. In ancient China, light snow was divided into three stages: "When the rainbow disappeared, it disappeared;" Second, the weather is rising and the atmosphere is falling; It was blocked three times and turned into winter. "

2. After entering this solar term, the northwest wind began to become a frequent visitor in China, and the temperature gradually dropped below 0℃, but the earth was not too cold. Although it began to snow, the amount of snow was not large, so it was called light snow. At this time, Yin Qi fell and Yang Qi rose, which led to the impassability of heaven and earth, the imbalance of yin and yang, the loss of vitality of everything, and the occlusion of heaven and earth into the severe winter. The first snow will appear in the area north of the Yellow River, reminding people that it is time to keep out the cold and keep warm.
