I feel much safer now after moving back to Shanghai from Sydney. There is no shooting in Shanghai whatsoever, but that seem to be pretty common in the western part of Sydney. Melbourne is now on another completely different level, you have gangs attacking each other using grenade.
One thing I really like is the fact that I can safely walk on any street of Shanghai at 1:00am and without the fear to be attacked or robbed, I won't be stupid enough to do that in Sydney or Melbourne.
