Another name for slight cold

Slight cold is the 23rd solar term among the 24 solar terms, the 5th solar term in winter, the end of the second month of the dry calendar and the beginning of the ugly month. It is celebrated every year from 5 to 7 on the Gregorian calendar 65438+ 10. Cold air is cold for a long time, and slight cold means that the weather is cold but not extreme. Like severe cold, mild heat, severe heat and intense heat, it is a solar term indicating temperature change. The slight cold solar term is characterized by cold, but it is not extremely cold.

In the slight cold season, the direct point of the sun is still in the southern hemisphere, and the heat in the northern hemisphere is still in a state of loss. The heat absorbed during the day is still less than the heat released at night, so the temperature in the northern hemisphere continues to decrease. After the winter solstice, the cold air frequently goes south, and the temperature continues to drop, and the temperature drops to the lowest during the slight cold and severe cold in a year. There is a folk saying, "It's 239 when it's a slight cold, and it's shivering with cold", which shows the cold degree of solar terms.
