Which department is in charge of fake pennants?

Managed by the administrative department for industry and commerce.

Therefore, according to the relevant regulations, when advertising companies make such plaques for others, they need to send personnel to the scene for interview and verification. Such banners or plaques are not allowed to be used for information that has false propaganda about relevant content. Otherwise, the administrative department for industry and commerce will severely crack down until the business license is revoked. If it constitutes a crime, it will be transferred to the public security organ for investigation.
