I second the warning. New Times International in Chengdu is a bad deal all around. The company plays middleman to various schools, Universities and even factories. Of course, in most cases, the middleman gets the lion's share of the wealth and you get the lion's share of the work.
When you finally realise you're getting about 30-40 RMB per hour, it's too late. If you try to leave, the owner (Irene) will use extortion tactics to hold you. If you persist in leaving her employment, she'll try to ruin your reputation and possibly accuse you of religious proselytizing. (Which can get you banned from China)
If you do decide to work for New Times International in Chengdu, expect to kick yourself hard in the butt later. You were warned.
