How did this ever get posted and not responded to?
Based on reputation alone, I have to recommend giving this one a miss. There have been near-continuous complaints voiced about this person and his company for longer than I've been involved with China and the teaching game here. They can't ALL be "lies"...indeed, some have come face-to-face from people I've known personally.
This name is often heard alongside those of others like Frank Zhang and James Ma, in the lists of the most notorious names in the business.
I can't recommend this company to anyone.
