Stories and legends of snow in the twelfth year

Xiaoxue is the twentieth of the twenty-four solar terms. 165438+1On October 22nd or 23rd, when the sun reaches 240, it is called the light snow solar term. At this time, the sun is at-2016' at the declination. On this day, Beijing's daylight saving time is only 9 hours and 49 minutes, and the height of the sun at noon is only 29 50'.

During the "light snow" solar term, 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.

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.
