Our SIL arranged for a private van and guide to take us to the Great Wall of China (Mutianyu). It was a two-hour ride from our hotel. Never imagined it was going to be hot up there. I always thought that it was a cold place, you know, being up there and all that. Our guide actually offered to take our coats before we went up. I later regretted not believing her hehe.
It was so hot that I actually got a tan after.
