I'm going to Yunnan next week. I wonder what the weather is like there. What should I bring?

Prepare clothes for spring and summer (the temperature here is already very good), a coat (the temperature difference is large, it is better to prepare a coat at night, otherwise the cold will be certain, unless you don't go out), and if you are a girl, you'd better bring a sun umbrella, otherwise you won't adapt to ultraviolet rays. Finally, enough RMB should be reserved in the bank card, otherwise it will not be fun to travel outside the bag. Hehe, I don't think I need anything else.
