Having no insight into the Chinese Psyche we are bemused why Chinese people wanted us to have our photo taken with them on our recent trip. It happened in places where we saw very few non Asian tourists. We obviously look quite different. Mainly young people would smile then indicate they wanted us in their photo. They are probably interested in the West from TV and movies, others wanted photos of us with their children. This happened on our last trip as well, in Lijiang a group of young Mongolians asked if we would be in a group photo.
This was not part of a scam.
