I have spent a good amount of time in the mainland as a foreigner. The way that men talk about women, particularly in professional settings, is decades behind imho. KTV alone - I have heard some pretty terribls sounding stories there as well although have been lucky to only have gone to the normal ktv. A simple example is booth babes at tech shows. In the US, general consensus is that this is exploitive. In China it seems quite normative.
