Or carry out surprise decoration during the night break to affect others' lives, you can complain to the public security department about this noise.

You can complain to the environmental protection department, such as the noise generated by night construction, enterprise production and catering service industry. Noise such as piling and concrete mixing on the construction site is directly supervised by the environmental protection department.
