Nice! I haven’t seen anything written by Reuven for a while, and just recently I was thinking about potential difficulties travelling in China in the ‘age of WeChat.’ Good to see his writeup.
FYI, every time I visit China, I write a bunch of things on Facebook about my experiences. (I know, lots of issues there, but it's convenient...) Follow/friend me there, and you'll see more about me and China!
