Heavy snow, beginning of winter, Solstice and slight cold are arranged in turn.

The order of slight cold from winter to day and heavy snow in early winter is: early winter, light snow, heavy snow, winter to day, slight cold and severe cold. These are six festivals in winter.

Slight cold, the 23rd solar term among the 24 solar terms in the lunar calendar, is also the fifth solar term in winter, which marks the official start of winter. When the sun reaches 285 degrees (slight cold) of the Yellow Meridian, it marks the arrival of the coldest day of the year in China.

According to China's meteorological data, slight cold is the lowest temperature solar term, and the temperature of great cold is lower than slight cold in only a few years.

During the slight cold solar term, people should pay attention to the forecast of strong cold air by meteorological stations, guard against the influence of strong winds, rain and snow on Spring Festival travel rush, and pay attention to cold prevention and freezing prevention.

There are some proverbs that predict the future weather, such as "a little cold and rainy will freeze the seedlings to death" and "a little cold and rainy will scare the seedlings to death".
