The same crimes that exist everywhere else in the world exists in China.
Yep. In China, as in every country, it is not the crime but the attitude towards the crime that is fascinating. Compare, if you like, the attitude towards prostitution in China and in Europe. Brothels in Denmark are hidden and illegal, as they are mostly run by horrible organized crime douches, whereas in China one can spot Pink Houses everywhere and no one seems to care. Also, I have recently been informed that, unlike other countries, riding your bike against traffic is, apparently, not illegal in China.
