Laowai who are living in China find themselves in the predicament of having a lot of time on their hands but not knowing what to do with it. However the COST of things in China isn't necessarily any less cheap than that of Europe or North Ameriica especially when it comes to electronic items, foreign alcohol, and general imported goods. These expats then realize that they're making the equivalent of above average salary in China where they're expected to live "comfortably". This leads to dangerous opportunities to meander and waste time indulging in things that can get them in trouble. This is an ongoing issue for a lot of teachers in China and the real problem is the lack of a caring atmosphere that can also make the teacher feel like they can talk about some things they feel uncomfortable with. Unfortunately most work places over in China don't offer this, so it comes down to experienced expats helping newer expats adjust to the environment.
