Yunnan ultraviolet intensity ranking

The following are the top three cities in Yunnan with ultraviolet intensity. First, Shangri-La. Shangri-La is the highest place in Yunnan, close to Tibet, so its ultraviolet rays are also the strongest in Yunnan. Second, deceive oneself and others. Mongolia's ultraviolet rays are also very strong, and most people who work on farms will get plateau red on their faces. Again, Yuanmou, because the weather is hot, and its highest altitude is 2836 meters, the ultraviolet ray is quite strong.
