Travel to Yunnan in two days, and ask for extra attention to dressing and other matters.

Sunscreen umbrella (men can wear hats, and umbrellas must not leave their bodies. Yunnan is famous for its strange weather.

suntan oil

Sunglasses (where the sun is dazzling at high altitude)

Coat+long sleeves+short sleeves+pants+a pair of comfortable shoes (clothes need to be changed, just a pair of shoes)

Everything else is basically for sale. Of course, you should bring your camera, otherwise it would be a pity to buy a spare battery.

There are disposable ponchos in scenic spots, so there is no need to waste space.

Take a nail clipper if you go for a long time.

There are also down jackets and oxygen bottles for rent in the scenic spot.

There shouldn't be many mosquitoes.

I went to Yunnan last month. Your itinerary is exactly the same as ours, but now I hear from my friend (who is doing business there) that the rainy season is coming soon.

Well, finally, have a good time.
