Travel to Yunnan tomorrow, Kunming, Dali and Lijiang for 6 days, and ask for a dress guide.

18 just came back. The following answers are mainly young people+sisters. If it's a man, I don't need a sunscreen. Please consciously use a thin trench coat instead of a thin cardigan. There is a big temperature difference between morning and evening in these places, and clothes are the same thing. When the sun comes out, you must have sunscreen lotion or sunscreen, and you must prepare a hat to protect your face. Kunming short sleeves and trousers are enough. If you are afraid of the sun, buy a thin sunscreen coat. It was really hot at noon, especially when I was going to Shilin, and I died directly. Dali and Lijiang, or want to go to Lugu Lake, just short sleeves+trousers+thin cardigan. Put on your cardigan in the morning and evening, and you can peel it at noon. If you want to go to Shangri-La, take a coat with short sleeves inside, and then buy a long scarf with better quality (around 20 yuan) at the stall outside the north gate of Old Town of Lijiang. If you are really afraid of the cold, take your thin cardigan and wear the middle layer as a sweater. It's not that cold. Of course, if you want to go to Lugu Lake to watch the sunrise, take your coat ... One of my sisters got up in the morning and caught a cold directly.

Besides, rain gear is a necessity this season. Besides the umbrella, I bought a disposable raincoat to carry with me. I also brought rain boots with me, which were used directly as boots in Shangri-La. It was very warm.
