What does the light snow solar term mean?

During the solar terms of 1 and "Xiaoxue", the bucket handle of the Big Dipper points to the northwest at night (equivalent to 10 on the clock). Every night after 20: 00, if you look at the stars at home, you can see that the Big Dipper sinks in the west, while the W-shaped Cassiopeia rises to the sky. Instead of the Big Dipper, she found the coordinates of Polaris and navigated for the stargazers. The quadrilateral Pegasus is facing the sky, and Orion, which symbolizes the winter starry sky, is already on the eastern horizon.

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.

3. Light snow indicates the beginning time and degree of snowfall. Snow is the product of cold weather. Light snow solar terms, the northern part of the southern region began to enter winter. "There is no rain in the lotus, but there are frost branches in the chrysanthemum", which has already shown the scene of early winter. Due to the barrier of Qinling Mountain and Daba Mountain in the north, the invasion of cold air is blocked and the severity of cold wave is reduced. The "warm winter" in South China is remarkable. The number of snowfall days in the whole year is mostly less than 5 days, which is much less than that in the middle and lower reaches of the Yangtze River at the same latitude. There is little chance of snowfall before the heavy snow. Even in the middle of winter, you can rarely see the charming scenery of "blowing open the petals of ten thousand pear trees". Because the surface temperature in South China is often above 0℃ in winter, it is more difficult to snow than to snow. Occasionally, although the sky is buzzing, there is no "broken jade" on the ground. In the cold northwest plateau, it usually begins to snow all the year round 10. The number of snowfall days in the northwest of the plateau can reach more than 60 days a year, and snowfall is possible in some alpine regions all year round.
