How cold is the winter in the South?

Minus two or three degrees. The lowest winter temperature in the south is minus two or three degrees Celsius, and rarely drops below minus five degrees Celsius. However, the coldness between the north and the south is different. In the south, there is not much difference in indoor and outdoor temperatures. In winter, it is very cold indoors, while in the north, the temperature is very cold. There are two different worlds outside. Wearing a thin woolen sweater indoors is just right.
