Shanghai is a highly developed International city.
I don’t know why so many people are demonizing it.
The only taboo is probably the politics.
It’s better to not make any comment about their politics.
But I will say the exact same thing when you’re living in a neighborhood supporting Trump in the US.
As for the firewall against certain websites on the Internet, I’m sure the locals know how to break it via VPN or anything like that. Nothing to worry about actually.
Just go ahead, @Andrew0409. You’ll be fine.
