Do I need to report to install billboards on the second floor?

Advertising signs need to be reported to the urban management. Doorway billboards are also called store signs or store signs and are included in the scope of outdoor advertising management. Many cities have clear requirements for the size and material of store signs. They need to go to the local urban management department to go through the approval procedures in advance. Only after approval by the relevant departments can units and individuals hang up and post advertising signs.
