You can take the metro and walk anywhere and not (...) worry about crime.
One of my favourite things in china. Every neighbourhood is safe. walk anywhere at any time of day and the worst thing that would happen to you is someone looking at you funny because they're not used to foreigners.
However,
We don’t see the omnipresent litter we do here.
A lot of chinese people do litter like crazy though. one of my least favourite things. a lot of good people, but enough of a percentage of shitty mentality that thinks dropping stuff on the ground and walking away is fine.
Also,
Seven, the qualitatively different nature of police relations with the people than here.
I'm sure american cops are a class of their own, but i'm not a huge fan of chinese cops. gong'an are usually alright, and might help you with stuff, but everyone absolutely hates chengguan, who are often corrupt and high on their own (limited) supply.
