Why is the epidemic situation in Yunnan not serious?

Special geographical climate. Yunnan Province, called Yun or Dian for short, is one of the 23 provinces in China, located in the southwest of China, with Kunming as its capital. The epidemic situation in Yunnan is not serious, which is not only related to the strict defense of thousands of kilometers of borders, but also related to Yunnan's geographical climate. With high altitude, strong ultraviolet rays and relative air circulation, the virus cannot survive for a long time. Compared with other provinces, Yunnan is more suitable for holiday and retirement, and its people are also relatively simple. Major enterprises can also consider coming to Yunnan to radiate Southeast Asia from here, so that their products can go abroad more conveniently.
