What's the weather like in Guiyang from March to May?

From March to May, Guiyang can be said to be relatively comfortable, and the highest temperature will not be above 30. However, because it belongs to spring to early summer, the temperature difference between morning and evening is relatively large, so we should pay attention to keeping warm in the clothing sooner or later. There is another saying in Guiyang that if it rains in winter, if you come to travel, you'd better prepare some long-sleeved clothes.
