What clothes should I wear to travel to Inner Mongolia in July?

I am from Inner Mongolia, and it is not very cold in Inner Mongolia. It's July, and everyone is wearing half-sleeved shorts and skirts. That depends on where you are going. If you are going to Hulunbeier, take more long-sleeved trousers and put on your coat in rainy days. It's quite hot to go to the central region. A half-sleeve skirt will do. Just wear a coat on rainy days. Don't worry, it's not that cold. We are all wearing half-sleeved shorts.
