The weather in Guangdong is really strange. Why is it always hot and cold?

No matter where the weather is, there is a temperature difference, with alternating cold and warm, but Guangdong is on the regression line, with a relatively high temperature and belongs to the tropics. At this stage, the temperature is precisely the most sensitive temperature for people. How many degrees people float up and down is the difference between hot and cold. It is very cold in the north, not a critical point, and it is not so obvious to feel cold and hot. Pay attention to the weather, clothes and health.
