What clothes should I wear to Xining on May Day?

It is appropriate to wear a long-sleeved T-shirt to Xining on May Day. Because if it is in the south, Xining needs to wear a long-sleeved T-shirt on May Day, and a coat should be added sooner or later, not a thick coat. It's good to suggest a jacket. Xining has high ultraviolet rays, so pay attention to sun protection, dry climate and drink plenty of water. Xining, formerly known as Tang Cheng, Xiping County, Shanzhou and Xiadu, is a prefecture-level city and provincial capital under the jurisdiction of Qinghai Province, and an important central city in northwest China determined by the State Council.
