What should I pay attention to when traveling to Xining in May?

1. Sun protection,,, the first element. . . 2. Altitude depends on your destination, Xining. Most people can come. It is no problem for people with normal constitution to walk below 3500. 3. Cold protection, it's still a little cold here at night, but it's not cold at noon and it's very comfortable. Take a good look at the altitude and weather forecast of the destination before coming. You can basically find it online.
