The origin of the great cold solar terms

Great cold refers to extremely cold weather. Time-sharing, time-sharing, time-sharing and time-sharing quote three rites and meanings: "Great cold is the middle, shaped by slight cold, so it is called great ... extremely cold, so it is called great cold." At this time, the cold wave frequently goes south, which is the cold period of the year in most parts of China. The wind is strong, the temperature is low, and the snow on the ground does not melt, showing a cold scene of ice and snow. The Great Cold is the last of the 24 solar terms in China. After the great cold, a new year's solar cycle is ushered in.

In ancient China, the Great Cold was divided into three stages: "One stage is chicken milk; Second, the symptoms of bird disease; Three times, the water is strong. " In other words, in the great cold solar terms, chicks can be hatched; Falcons such as eagles are in a state of strong predation ability, hovering in the air to find food to supplement their body energy to resist the cold;

Like slight cold, great cold is also a solar term representing the degree of cold weather. Modern meteorological observation records show that in most parts of China, severe cold is not as good as mild cold; However, in some years and a few coastal areas, the annual minimum temperature will still appear in the severe cold solar terms.

In addition, the people of the whole country also use the change of cold climate to predict the rain and food abundance in the coming year, which is convenient for arranging farming as early as possible.

For slight cold and severe cold, it is the period with the least rain in a year. During the cold solar term all the year round, the rainfall in most parts of the south only increased slightly compared with the previous period, with 5 ~10mm in most parts of the south and only1~ 5mm in the mountainous areas of the northwest plateau. During the winter drought in South China, the water consumption is small, and the contradiction between supply and demand of farmland water is generally not prominent.
