What will the weather be like in Jiuzhaigou at the end of May? What will you wear in the morning and evening? What other precautions are there? I don't have any points. I hope I can understand.

There is a great temperature difference between morning and evening. Generally, if you go to Jiuzhaigou, there will be a party on 150. You still need long sleeves at night. You can bring a set of short sleeves, jeans and a thick coat, because it will be cold in the mountains. If your schedule is tight, you must get up early, it's cold. Hehe, take daily necessities, camera, water and food when you go out.
