The meaning of solar terms and solar terms proverbs in severe cold

There is a saying in the older generation that winter in severe cold is the coldest time. In fact, this statement is not quite correct, and it does not mean that cold will definitely reach the extreme of cold. Most of the time, the slight cold is the coldest time of the year, but in a few cases, the great cold is colder than the slight cold. That's because it was too warm in the slight cold, so I moved the cold to the great cold.

"Give a General Examination of Time" quotes "Three Rites and Righteousness": Great cold is the middle and shaped by slight cold, so it is called the extreme of great cold, so it is called great cold.

At this time, the cold wave goes south very frequently, which is the cold period in most parts of China in a year. In this solar term, it is characterized by strong wind, low temperature and no snow on the ground, showing a cold scene of ice and snow.
