Well, if you want to get paid over 4000 RMB a month, language teaching is probably your best option.
1) Lie on your english teaching resume. Tell them you have at least 2 years of experience teaching english to some fortune 500 in your home country or something.
2) Native speakers should get minimum 150 an hour from semi-respectable firms, 120-130 from the little ones, and at least 200-250 for anything involving corporate training
3) you gotta get your ass in gear immediately to find a job if your coming during that time, because the "Chinese new year" will take place around then and it will be a shitshow for about a month (I think mid-feb this year?) During that time most companies
will close and you will only be able to find part-time work at best.
