How to complain about noisy upstairs decoration?

You can take the following measures to complain: 1. Complain directly to the upstairs owners or decoration workers and ask them to reduce the noise. 2. If direct communication fails, you can complain to the property management office or the industry committee and ask them to coordinate and solve it. 3. If the above methods are ineffective, you can complain to the local urban management department or environmental protection department and ask them to intervene. When making a complaint, it is suggested that you provide a detailed description of the time, place and noise situation, so that the relevant departments can better handle the problem.
