What's the weather like in Gansu in September? What clothes do you need to wear?

Gansu is very big, and the temperature difference between different places is quite large in September.

It is mostly sunny during the day in September, and there may be heavy rainfall at night.

If you are in Lanzhou, just wear a T-shirt, pants and a thin coat in September.

If you want to go to Hexi, you'd better prepare a set of autumn clothes and trousers.
