The origin of heavy snow solar terms

On February 7th or 8th of every year 12, when the longitude of the sun reaches 255 degrees, it is "heavy snow" which is one of the 24 solar terms. Heavy snow, as the name implies, has a large amount of snow. The ancients said: "The great man is prosperous, and the snow man is prosperous here." . At this time, it often snows heavily and widely, hence the name heavy snow.

At this time, the lowest temperature in most parts of China has dropped to 0℃ or below. Often, in areas where cold and warm air meets strong cold air fronts, there will be heavy snow or even blizzard. It can be seen that the solar terms of heavy snow indicate the starting time of this period and the degree of heavy snow, which, like the solar terms of light snow, rain and Grain Rain, directly reflect the precipitation.
