High score reward, is it legal for supermarkets to hang advertisements or banners on their door eaves?

Hello, I run an advertising company and I often have to deal with advertising approvals, so I understand the situation you are talking about. I am an advertising reviewer myself. The urban management's law enforcement is legal. Since they want to demolish you, there is nothing they can do about it. However, the urban management in some places is not so strict and will not care about you. The legal procedure for advertising is as follows. The publisher provides an advertising design sample, and then takes a copy of the business license to the local industrial and commercial department for review. If there are no problems, the industrial and commercial department will issue a certificate agreeing to publish the advertisement. After obtaining the certificate Go to the urban management department to apply for release. (Note: There is no charge for industrial and commercial administration. Urban management charges 80 yuan per square meter for advertising and 60 yuan per banner. This charging standard is our standard. You have a local price department there. ), the urban management fees are too high, so few of us are willing to go through the process of approval. At most, we can tear it down and build another piece.
