The leaders of Aston will promise you a lot and give you little. Meaning, they've got a good rap but little more to offer. As for Aston in Chengdu, well, it couldn't get much worse from what I've heard. Aston's favorite lure is to offer you long term employment that will lead to a supervisory position. Communicate with them for awhile and you'll see what I mean. Stop communicating with them for a few days and they'll drop you like a lead balloon because they'll suspect, rightfully so, that you're checking them out.

As has been said repeatedly here and in other forums, avoid Aston no matter what they offer you. In fact, be very careful about private schools in general, but put Aston right near the top on your list of schools to avoid.
