Can the property always knock on the door and call the police?

If the property keeps knocking at the door, which disturbs the normal life of the owner, you can communicate with the property company first to understand the situation and resolve it through consultation. If negotiation fails, you can call the police. According to Article 58 of the Law of People's Republic of China (PRC) on Public Security Administration Punishment, anyone who violates the legal provisions on the prevention and control of noise pollution in social life and creates noise to interfere with the normal life of others will be given a warning. If no correction is made after warning, a fine ranging from 200 yuan to 500 yuan shall be imposed.
