You can try to contact Bin Wang. He is a real estate agent. He should be able to find your friend a condo or you can inquire some information. You can find his ads in local Chinese newspapers.
It is a good idea to get information from several agents if you have the time. The reason to deal with Chinese agents is mostly the language. If you are comfortable with English, then you can always get English speaking agents. I think most agents are fairly reasonable. It is safer to deal with agents than to buy properties through private sales.
