Well Chinese teachers do have a tendency to bang students too, but are far more discreet, often acting like sugar daddies rather than just f**king them and chucking them. Same crime, but they tend to go about it in a far more (albeit falsely) professional way than the average horny young laowai. That being the worst kind of ‘professionalism’ that is not even professional at all, where all they are actually doing is avoiding bringing the university into disrepute, rather than behaving in the correct way in the first place.
