The weather in Guanzhong in September

First of all, I am from Xi, so I am qualified to answer this question. Although it is already beginning of autumn, the weather in Guanzhong in September is still very hot. There is a big temperature difference here in the morning and evening, so clothes should be added in the morning and evening. But it's hot at noon. Wear short sleeves. Wear a coat sooner or later. It entered the rainy season in mid-September and rained for a month.
