Schools use agents to distance themselves legally from your inevitable deportation.

I have tasted unripe lemons that are not as bitter as you seem to be. Did some nasty FT steal your dolly?

If you cannot contribute anything other than snide, insulting remarks, why bother?

I (and every one of the 40+ foreign teachers that I know and have worked with in China) found
each of my positions directly by contacting schools.

Well 'woopy-doo!'

I recently gave the contact information (for a good agent), to one of my friends who is looking for a new job. (This guy has more degrees than a thermometer BTW). Within 24 hours my friend had the pick of no less than 8 high school / university jobs in 8 different provinces. He didn't have to send 8 lots of documents off to 8 different schools, nor did he have to sit through 8 interviews.

If you are a lazy unqualified ignorant foreigner, by all means: use an agent to get a job in
China.

Agents have their place. Whether you choose to use them or abuse them, some of them do a fine job!
