Beijing and Meijia real estate agency?

Have you ever met a black intermediary? It seems that many small agencies have it. Besides, why not find a big company? Why go to a small company? I wonder if there will be many pits in it? Encounter this kind of thing, go to the construction Committee to complain, or call the police directly. Anyway, I'm going to teach you a lesson this time. No matter what you do in the future, you'd better find a regular big company, so that your rights and interests can be guaranteed.
