What clothes should I take to travel to Yunnan on March 20th?

I don't know where you are going. Kunming 20 is 24 degrees in the daytime and 10 degrees in the evening. The temperature difference is quite big. Lijiang in Dali will be cold at night, so you need to take a coat. If you want to go to Xishuangbanna, it will be summer directly. Be careful of heatstroke. The weather forecast says it will be cloudy and sunny, but the wind is so strong tonight that I don't know whether it will rain or be cloudy tomorrow.
