What clothes and shoes should I wear when going to Kunming, Dali, Lijiang, and Banna from September 24 to October 1?

The main characteristic of the weather in Yunnan is the large temperature difference between morning and evening. You can wear autumn clothes at the end of September. To be specific, autumn clothes + autumn pants + thin sweaters, but it will be very hot after the sun comes out at noon, and the temperature will reach 20 No matter how hot it is, a shirt can handle it, but it will only be less than 10 degrees at night.

Put it this way, whatever you wear at the place of departure will be enough when you arrive in Yunnan.
