What's the weather like in September in Qiandongnan Prefecture, Guizhou Province?

I am from Kaili, the capital of Qiandongnan Prefecture. The weather has been fine recently, but I don't know in September. Remind to keep warm and bring autumn clothes. If camping needs warm equipment for the night. It is rainy here. As the old saying goes, there is no sunny day for three days, no flat land for three miles, and no silver for people. Hehe, the last sentence needs to be changed. . . Qiandongnan people are very hospitable, so the landlord should pay attention to exercising his capacity for drinking.
