Is Yunnan easy to turn black?

It's easy to get sunburned on the plateau because of the high ultraviolet rays! ! !

In July, I went to Dali, Yunnan, and took a cruise to Erhai Lake. Attention! On this sunny day, I was completely tanned, one arm was black and the other was white. People there have dark red skin, so be sure to take high sun protection measures! ! ! !
