Name Change Question

My wife and I were not married when we got our jobs in Shanghai and applied for our Z- visas. Our school did all the paper work for us and sent us our z- types in the mail. However my wife has changed her name to take my last name and she also got a new passport. Will this impact our ability to get residence permits upon arrival and have you heard of anyone else who has had a similar experience? We have a marriage certificate and we also have my wife's old passport.
