You should have only advertised the jobs through a couple of reputable Chinese recruiters.

No doubt you know why for the most part Chinese recruiters don't name the schools/colleges/training centers they're trying to find foreign faces for. That's for two reasons. First and foremost, there are dishonest foreigners who will try to cut them out of their commissions from propective employers by dealing direct with said employers once those foreigners have gleaned the necessary detailed contact information they need. such foreigners can then make a itte more money by splitting the npaid commission with their new employers, unethical in essence! Second, recruiters poach one another's employer leads to increase the number of jobs they have details of. many recruiters will try to do this. As a jobseeker, the only time you'll be given full details of an employer who's eager to offer you a job is when you've agreed to sign a scanned contract through the recruiter. Recruiters distrust employers too - they won't furnish them with a job hunter's contact details until an employer has offered a job througn a recruiter to a foreign face, which is the only way it can be done in any case, due to the safeguards that Chinese recruiters impose on both parties they're trying to bring together. Logical and necessary, given the unprofesional behavior of both Chinese employers and foreigners that is rife here on the mainland.
