I'm going to Yunnan (Kunming, Lijiang, Shilin, etc.). ) April 265438 to April 29. What kind of clothes should I wear? What other precautions are there?

Just wear a T-shirt and coat here. It's about 20 degrees, so it's good to wear a pair of casual shoes. Bring some sunscreen skin care products, hats, sunglasses and more money. Take a bag instead of a box. Otherwise, it will be uncomfortable to drag. After being in Kunming for so long, I basically feel that except for a few days in winter, it is spring and it has never snowed.
