Count nine weather changes.

The coldest period in winter usually occurs after the winter solstice. After beginning of winter, it means that it has entered winter, but it doesn't mean that it has started to get cold. So the heat stored on the surface in the second half of the year still has some energy, so it is not very cold.

There is a folk saying that it is "a spring in October". "Xiaoyangchun in October" refers to the sunny, warm and comfortable "Xiaoyangchun" weather during the winter. So early winter (Meng Dong) is generally not very cold, but with the passage of time, cold air frequently goes south and the temperature gradually drops.
