The lowest temperature in winter in Nanning, Guangxi

I come from Nanning. My own experience and listening to the old man say that it hasn't snowed here for decades. Under normal circumstances, the lowest temperature in the whole year is during the Spring Festival, and the lowest temperature is 2-3 degrees. The coldest time in recent years was the snowstorm in southern China in 2008, but it didn't snow either, but the temperature was low. Under normal circumstances, a thick coat+sweater+thermal underwear can be used for winter. It's cold when it rains in winter, just like when the snow melts in the north. Because Nanning is located in the south, there is no hot pit and heating in the north, so northerners will not be used to it.
