Great cold is the coldest time of the year. Do you know how to calculate the time of severe cold?

Twenty-four solar terms are the crystallization of ancient laborers' wisdom in China, which shows the changes of cold and heat in a year, and divides the four seasons of a year into twenty-four small segments, each of which has corresponding farm work and weather and climate problems, and severe cold is the last festival of the twenty-four solar terms in a year.

Like slight cold, great cold is also a solar term indicating the change of cold weather. Slight cold means that the weather is getting cold, and the air conditioner has been getting cold for a long time, and it won't be long before it reaches the great cold. During the severe cold, the cold current often enters the south, and most parts of the country reach the coldest stage of the year, showing a cold wind and freezing change. But after the severe cold, the weather began to pick up slowly, and the soil temperature began to pick up, so spring was needed.

Five days after the great cold, the Spring Festival is coming. In order to celebrate the Spring Festival, everyone has prepared for more than half a month in advance. Although the weather is cold, it can't stop everyone's yearning for the Spring Festival. It is especially cold in the cold season, especially in foggy days. Many areas are filled with white fog all day, mixed with breeze, which makes people feel chilly.

As the cold current moves southward, there are cold conditions such as strong wind, ultra-low temperature and road snow in many areas, especially in some parts of the north, where the air relative humidity is high, foggy weather often occurs and sunny days are rare. Although severe cold indicates extremely cold weather, there are some areas in China where severe cold and slight cold are not comparable.

Although the relative humidity of the air is high, slight cold and severe cold make it rain at least once a year. As soon as the severe cold is over, the Spring Festival will begin, and the new year needs to begin. The 24 solar terms of the New Year begin to cycle, and spring is coming. Therefore, after the great cold, there is little snowfall, and there will be no severe cold in the winter solstice solar terms. Therefore, the great cold does not represent the coldest stage of the year.

In the cold, everyone is busy saying goodbye to the old and welcoming the new, and preparing for the Spring Festival in advance. Although the weather is very cold, everyone keeps warming Xiao Qiao in order to welcome the New Year, which also relieves everyone's physical cold psychologically. Spring Festival is an important traditional festival in China, which has a vital influence in our hearts. No matter what the external conditions are, it is impossible to celebrate the folk custom of the Spring Festival, not to mention the cold weather. In fact, there are many folk customs behind the great cold.
