The exterior walls of residential areas belong to all owners, and no unit or individual has the right to install advertising light boxes and LCD screens privately. Any wall modification must be approved by the owners' meeting. Mr. Shi installed billboards privately in the early morning of June 16 without informing the property and industry committee, and the property company has the right to stop it. On the afternoon of July 26, a door blocking incident occurred in the community, and the owners felt very angry.

In the interview, Mr. Shi admitted that he set up outdoor billboards without the approval of the municipal department. The reporter learned from the City Appearance Advertising Section of Guigang Municipal Bureau that when setting up billboards outdoors, applicants need to go through relevant procedures and obtain a permit for setting up outdoor advertisements before setting up them.
