I was that back in 2006 when I went to Yuncheng to work for Yuncheng IELTS School, an agent that fulfilled the same role in the Yuncheng area of Shanxi as Enfly does for the whole of Sichuan.

My outfit only employed around 20 foreign teachers, but I was paid 5,000 a month for 16 classes a week, with my own teaching assistant, provided and paid by the company. She was a young Chinese college graduate who assisted me in planning the weekly 45 minute lesson to be taught 16 times in her presence at a state senior high school to first graders. She did the discipline and classroom management, as well as translation and interpretation in class, if necessary, at that county high school. The job was not at all stressful, and some of my colleagues, who were non native speakers with poor English, were able to fulfill their contracts easily, too. The cost of living in that pikey town was a bit higher than Yuncheng itself, which, as I subsequently discovered, was not unusual in China. My accommodation was provided by the company rent-free, and my apartment had a desktop computer. 5,000 a month in those days was good pay compared to what it would be now for obvious reasons.

You can make the comparison with Enfly. It's a no-brainer which of them would be the better employer of the two!
