I want to go to Mount Tai in May. I checked, the weather is about 20 degrees. What should I wear to climb the mountain? Can I wear short sleeves?

I told you from the experience of local people in Tai 'an that climbing Mount Tai on May 1 is a kind of torment, and you can't see anything. There is only a sea of people, but the weather should still be cold. You should wear thick clothes. If you want to see the sunrise, you should stay at the top of the mountain for one night, but the hotel is very expensive. If you go on holiday, it's probably nothing expensive. You can consider going again or bring a tent. You can rent a coat at the top of the mountain. It is cold and cold at night. . . . I don't accept so many answers. . . It's already very detailed
