Yes The Wenzhou D.D. Dragons are fine. It's the Cangnan (Ling Xi, and Longgang) D.D. Dragons you have to watch out for. They say they can get you a Z visa but they can't. They trap foreign teachers there and tell them they will have them arrested in Shanghai if they run away. They say you are in Wenzhou but you are two hours away from anything western. They make foreign teachers stay in their apts. all night, and don't let them have friends or family come to their house. It's a locked down school where they are forced to work and pay is randomly taken out of their checks with no explanation given. Stay away from those schools. They have troubles getting and keeping teachers their they they have to recruit under the alias of Austin English.

Sincerely,
NM
