The rule is very simple: Don't give any shit to anyone in the host country where you are; and
don't ever accept any shit from anyone there where you are.

Turnoi, you are right. In any Chinese work contract that I have seen, there is a requirement to 'abide by Chinese law' and I have no issue with that. However, we should all stand up for ourselves if and when someone tries to screw us - just as we would at home.

The problem appears to be that too many westerners complain about certain Chinese social behaviour. If a Chinese person in YOUR country starts spitting on the restaurant floor, drives on the pavement or pushes in front of you in a queue, then you have the right to complain. Just because westerners behave differently doesn't make Chinese behaviour 'wrong' - just not acceptable to us. But we are in THEIR country, and as such we have no right to complain per se.

In all my time in China, (on-and-off since 2009), Someone's only tried to 'screw' me twice. On both occasions I 'screwed back' much quicker and took great satisfaction from doing so. But let's face it, people try to screw us at home too!
