What is the meaning of the Great Cold solar term?

Least rainfall in a year
During the Great Cold season, the average temperature in most parts of southern China is 6℃ to 8℃, which is nearly 1℃ higher than the Lesser Cold. The proverb "Lesser Cold and Greater Cold, it's extremely cold" indicates that the Greater Cold is also a cold period of the year. Lesser Cold and Greater Cold are the periods with the least rainfall in a year. During the Great Cold season every year, rainfall in most parts of southern China increases only slightly compared with the previous period, 5 to 10 mm in most parts of south China, and only 1 to 5 mm in the northwestern plateau and mountainous areas.
Which is colder, the Greater or Lesser Cold?
Lesser Cold is generally colder than Greater Cold. The "Three Nines" of midwinter are basically within the Lesser Cold solar term, so the coldness of Lesser Cold lives up to its name "the coldest in the Three Nines". This is because during the previous solar term, the winter solstice, the ground surface received the least sunlight and heat, but there was still heat supplement from deep in the soil, so it was not the coldest time of the year. After the winter solstice, which is around the "Three Nines", the heat deep in the soil is also consumed. Although the amount of sunlight and heat increases slightly, it is still not enough, so the lowest temperature of the year appears.
