Not for you, teaching in China, that is. You are a male, but how about Western females? I'd say from a female FT's perspective the dirt, pollution and the interaction with local people in the street may well be more problematic, especially the staring. But overweight Western females are actually respected, and receive better treatment. The local logic is that they must be rich because they are fat, and therefore are looked up to!
At work, female Western foreign teachers are better treated, by students, who will be less inhibited than they will be with Western male foreign teachers. The Chinese staffs know that many are non-smokers, won't get pissed and behave ignorantly, and won't flirt with beautiful Chinese students nor visit whorehouses, which Western men may well do. Also, the female Chinese teachers of English won't feel inhibited about befriending them. In contrast, said Chinese won't befriend Western males. They are well aware that can cause malicious gossip!
Western females who can bear bad street manners and dirty surtoundings should come to China for teaching. the Chinese education providers actually prefer them, as do many Chinese students.
As for me, I'm a Western male who has lived and taught happily in China for many a year. Horses for courses, as it were!
