All those answers sound honest at least. I bet the salary one got the job!

I recommend you get a TEFL or TESOL certificate before you arrive or you can attend a course here in China. There are also online courses you can take - This will get you qualified.

The OP is still an undergraduate and will not finish his degree until December, but is looking to come here for work in July. As such he will not be qualified for a work visa.

@OP
I think you need to first know what is required for you to teach 'legally' in China. No sense coming here ill prepared and having to go back.

"to have a bachelors + 2 years working experience " ..is that only for teaching English or any work visa? Can anybody provide a link to some official website about this matter, please? Thanks

Don't forget the 'criminal background check' and the age restrictions.

Thanks Liumingke. It seems to be just about the teaching job.
I would be interested to find a details about other jobs requirements.
