My agent, Mr. Yang, is a very nice one. He can speak Chinese quite well (he is from Singapore). Currently, we are in in the process of buying a new house. He is very patient and provided us a lot of good sugguestions on choosing the lots/model.
He was our agent when we bought our first house (it is an old house). He never pushes his client to make a decision if they are not ready. It is very important for us. This time, we found that having an agent could be quite helpful even for buying a new house. I would sugguest you to get a nice agent.
Mr. Yang may not share the commision for buying a new house. We didn't ask him about it since we feel he works very hard for earning his commision. If you like, I can send you his contact information.
