I spent almost 10 years in Beijing (2007-2016), and it seemed like everyone knew everyone. I was off a bit, there are 500,000 foreigners in Tokyo, compared to around 600,000 foreigners in China:
Wow, that's a long time, I was there during your time so we might have met. It's true that everyone seemed to know everyone :) I guess I was just surrounded by this expat community hence why I felt like it was so big.
Weird question but did you know TUN bar? Last time I was in BJ it was closed and I was really sad about it :(
Do you have a source on that?
SZ didn't seem to have any foreigners when I was there. The expat community of BJ is pretty crazy for having spent a year there.
