What's the weather like in May in Hezuo City, Gannan Prefecture, Gansu Province? I want to travel there and I don't know what clothes to bring.

Gansu has a long and narrow terrain and climate characteristics, with the Yellow River as the boundary: Hexi area is different from Hedong area. In May, in Hexi area, you should wear shirts and coats in the morning and evening. You can wear a shirt at noon.

Hedong (Pingliang, Qingyang, Hexi), (Tianshui, Dingxi, Lanzhou, Longnan and other places) can wear shirts all day. Gannan is a little cold, and shirts and coats are necessary all day.
