I want to set up a small advertising column in the community. I will maintain it. Can I charge a fee\?

First of all, you need to find the city appearance approval unit in your area and submit an application, including original pictures and renderings of your setting form, content, and location. Residential roofs also require approval from the housing management department, and the building (permission letter from top-floor residents), and applications for billboards on residential roofs are generally not approved.
