What's the weather like in Longnan area? I'm going there on business.

I don't know where you mean, Longnan is still a place with a relatively large temperature difference between counties. It is hotter in Wudu and Wenxian. Chengxian, Dangchang and Xihe. Lixian is cooler. See where you're going. If it is Wudu district, short sleeves will feel hot. Hehe, I usually have big underpants, and I have no clothes to wear on them at home. You don't wear a T-shirt before you go out.
