Which unit is responsible for rural murals?

County and township construction departments.

Make posters on rural walls, and all the expenses can be allocated by the township government finance office. If it is not unified construction, there is no supervision unit for the external wall decoration of rural single buildings. If it is a unified new rural construction, it will be supervised by the county and township construction departments. Policies such as family planning, conscription, compulsory education and environmental sanitation are outsourced by the government to advertising companies. And those advertisements, such as infertility, compound fertilizer or cement, were bought by the manufacturer after consultation with the owner of the wall. Finally, there are humorous graffiti, which is purely personal entertainment. I hope my answer can help you.
