Yes, if you want to live easy working in China can indeed be a good choice. If you want to have a career in which you excel, advance, get promoted, become part of the company, and go with them into the future as a part of it, think again, this won't happen in ESL. If working for a public school the reasons are obvious, if for a private one, again, obvious reasons. If career and advancement are important to you, don't come to China, that's for certain.
