Matters needing attention in going to Yunnan in mid-September.
1, September in Yunnan is summer, and short sleeves are the main dress.
2. It is recommended to take a coat when traveling, because the temperature difference between morning and evening in Yunnan is large, and the temperature difference between morning and evening is about 10 degrees. It is recommended to take a thin coat when traveling to Yunnan in September (in order to increase clothes according to the weather in the morning and evening to avoid catching a cold).
Besides, you should also bring a sun hat, sunglasses, sunscreen and umbrella (you can use these things whenever you visit Yunnan). After all, Yunnan belongs to the plateau area, with long sunshine time and strong ultraviolet rays.
