Travel to Yunnan, China :: Perfect for summer trips!

What is the best Chinese province for a summer holiday?
I am not highly recommend to go Shanghai or Beijing in summer. It is so hot!!!!
You should go to Yunnan in the western part of China.
If you search for Yunnan in the internet, it is said that it is not suitable to travel because the summer is always rainy.
But the locals say that summer is proper time to travel around Yunnan.

Check out the iPhone weather app, it's raining all summer, but it's not always raining when you go to Yunnan.
It is usually showering about 30 minutes.
The weather is a little bit cool that there are many times that you need to wear long sleeves, even in the daytime.
Because of the high altitude, sunscreen is essential.

You can actually meet such a clear day very often.
It is recommended to go to such beautiful area by all means in summer.
