How can owners protect their rights if the community is poorly managed?

Article 83 Owners shall abide by laws, regulations and management regulations.

For acts that damage the legitimate rights and interests of others, such as dumping garbage at will, discharging pollutants or noise, raising animals illegally, building illegally, occupying passages, refusing to pay property fees, the owners' assembly and the owners' committee have the right to ask the actors to stop the infringement, eliminate the danger, remove the obstacles and compensate the losses in accordance with laws, regulations and management regulations. Owners who infringe upon their legitimate rights and interests may bring a lawsuit to the people's court according to law.

I suggest you reflect this problem to the owners' committee first, and then negotiate with the property manager. If negotiation fails, a lawsuit can be taken to jointly sue a number of owners trapped by noise. This is the only way. This is the normal way.

Good luck!
