Why can't the Great Cold get married?

It is superstition that the cold can't get married. In ancient records, "extreme cold is called great cold". On the day of the great cold, the cold is the strongest, so the ancients generally did not get married in the great cold. The Great Cold is the last of the 24 solar terms. Every year around 65438+1October 20th in the Gregorian calendar, when the sun reaches 300 degrees on the Yellow Meridian and is at three or nine o'clock, it is called "Great Cold".
