July 1 It takes about 8 days to go to Lhasa. I wonder if there will be many people in Lhasa these days. How's the weather? What are the precautions?

This season is the best time to travel to Tibet, that is, there are many people and it is often difficult to find a room. There is definitely nothing to say about the weather, and the blue sky and white clouds will make you linger; Anti-ultraviolet, should not bear too much weight; According to your itinerary, I suggest that you don't need to go to Everest, because you can't see the peak of 8848. If you insist, I can only say that you are challenging and experiencing a higher level.
