Is it illegal for owners to hang banners in the community?

Legal analysis: the government can hang up, but the people can't. There is a case: there is a dispute between the owner of a residential area and the property, and the owner plays a banner of rights protection. The main content is to protect rights according to law and pay reasonable fees for our green space. Next, the city management advised that it would affect the city appearance and sanitation. If the owner does not listen and continues to hang, the urban management will forcibly remove the banner. The owner fought with the urban management to protect the banner. As a result, the police went to court and said that the owner refused to hinder the staff of state organs from performing their official duties, and finally detained the owner. If the owner refuses to accept it, there is no way to sue. Some things are unclear from the legal point of view.

Legal basis: Article 53 of the Constitution of People's Republic of China (PRC). People's Republic of China (PRC) citizens must abide by the Constitution and laws, keep state secrets, cherish public property, observe labor discipline, observe public order and respect social morality.
