Of course it is a volunteer gig Shawna! But I doubt it is still worth it for single people, or even people with savings, lets go over the latest ad from footprints recruiting, if i may:

http://www.eslcafe.com/joblist/index.cgi?read=22534

It mentions something like 26 teaching hours a week, consider in China even at a training centre you would only have 25 hours a week class time, your own apartment, and higher pay.

Is a complete lack of privacy, low pay, high teaching hours in a crime ridden country worth it?
