Violent Students

You may also want to talk to some teachers that are already in the country, there are many reasons for doing this. However one very important thing to ask is the general attitude of the students. My boss worked in poland for a couple years and he was threatened with a knife by a student on more than one occasion, Chinese students won't do anything unless you threaten them and they will make you pay for that later. And yes teaching is a very stressful job, drinking to much can be a problem especially in asia because it's usually cheap, save for in Japan. Also make sure the school or institute you are working at is in a bigger city or at least a well populated area. Foreign english teachers get found dead all over the world, it's much easier to get someone out of a contract with no hassles if they are dead. This of course is something rare and most people avoid it by being in big cities. The culture you will be living around is going to be very different, I still don't get certain things about China, and it's likely I never will. You will need to get used to this, I hate the hard time I have communicating with some of my co workers for example, but they are Chinese I am lucky they are speaking english at all.
