What do you mean by a slight chill?

A solar term indicating the degree of cold weather

0 1, slight cold and severe cold

Slight cold refers to the cold weather, but it has not reached the extreme, so it is called slight cold.

Great cold means: extremely cold, very cold weather.

Moral of the Great Cold: The coldest period of the year is coming.

02. The difference between slight cold and severe cold.

1. After the winter solstice, the direct sunlight will gradually move northward, but for a period of time, the direct sunlight will always be in the southern hemisphere, and the heat in the northern hemisphere will always be lost, and the heat absorbed during the day is still less than the heat released at night. Therefore, after the winter solstice, the temperature in the northern hemisphere continues to decrease, and slight cold and severe cold become the two coldest solar terms in a year. As the saying goes, "It's 239 when it's cold, and I'm shivering with cold." . This shows the cold degree of the slight cold solar terms.

2. Every year around 65438+10.20, when the sun reaches 300 degrees of the yellow meridian, it is a great cold. The ancients thought that the "day" of alternating cold and summer was to recover quickly after a cold. If you get a bad cold before the slight cold and can't feel "recovered" after the coldest, then you can put the bad cold behind you and let it go back to beginning of spring. This is in line with the way of "extremes meet". There is also a saying that the slight cold in winter corresponds to the "slight heat" in summer, so it is called "slight cold"; The severe cold in winter just corresponds to the "great summer heat" in summer, so it is called "great cold"
