Bian Xiao tells you the origin of slight cold.

When the meridian of the sun reaches 285 degrees, it marks the arrival of the slight cold in the 23 solar terms. A slight cold in the middle means cold, and a small one means the degree of cold. The slight cold weather is characterized by frost and snow, accompanied by freezing. So, do you know the origin of the solar term slight cold? Next, let's take a look!

The origin of slight cold

Slight cold, like severe cold, mild summer heat, severe summer heat and intense summer heat, are all solar terms indicating temperature changes. "Twenty-four solar terms" says that "the cold is still small at the beginning of the month ... it is big at half a month", that is to say, in the Yellow River basin, the cold at that time was colder than the slight cold. And because the slight cold is still in the last few days of February 9, it will take a few days for the slight cold to enter March 9, and the slight cold in winter corresponds to the slight heat in summer, so it is called slight cold. The Great Cold, located after the slight cold solar term, slept like a camper in Kuya, and the "April 9" was also very cold, while the great cold in winter coincided with the great heat in summer, so it was called the Great Cold.

The characteristic of slight cold is that the weather is getting cold, but it is not cold yet. The "March 9th" in the middle of winter is basically within this solar term, so there is a saying that "slight cold is better than severe cold". This is because on the solstice of last winter, the surface received the least sunlight and heat, but the heat in the deep soil supplemented this, so it was not the coldest time of the year. From the solstice after beginning of winter, around March 9th, the heat in the deep soil was also consumed. Although the sunshine and heat increased slightly, it still made ends meet, so the lowest temperature in the whole year appeared.
