I want to launch a questionnaire survey in my community. I need to use the bulletin board downstairs. Do I need to notify the property management office?

Be sure to say hello to the property and get permission before using it. Otherwise, do you know what will happen to wild advertisements? All the pieces I tore up for you are left behind. At least, greeting is to respect each other, and the other party will tell themselves that the cleaning staff will not tear your things. It's different to charge or not. If you charge, you should. After all, you use the supporting facilities of the community, if it is profitable.
