Is it illegal for the owner to put up a no-smoking sign and be torn off by the property?

According to the information of the Property Management Office of the Real Estate Administration, since the property has the right to tear up the notices posted by the owners, the owners of residential quarters must inform the property in advance when they need to post the notices, and post them to the designated location with the consent of the property. Without the consent of the property, it is not illegal for the owner to scribble privately, which will affect the cleanliness of the community.
