Is it heavy snow or cold?

The Great Cold is the last of the 24 solar terms in China, which indicates that the weather has become very cold. During this period, because the direct position of the sun is in the south, the surface receives less sunlight, and the north wind will also strengthen, resulting in a drop in temperature. Heavy snow doesn't necessarily mean that the temperature is very low or there is the most snow, but it just means that there will be a certain weather and precipitation pattern during this time.
