How to deal with the building manager

1. Make sure the noise is caused upstairs. Be sure.

2, at 9 o'clock in the evening, neighbors can bear it. But not often, only occasionally, children can't help it.

3. It's afternoon 10. If you can confirm the upstairs or the morning, the countermeasure is to talk directly with the upstairs. This is called giving gifts before the soldiers.

If it is still ringing in the back, take a recording device and record it. Remember not to turn it off. Go upstairs and knock on the door, and record the conversation, too. Save.

5, you are looking for the police in a residential building, and the police will solve it properly. If it is a commercial building, you can ask the Environmental Protection Bureau, and they will come to test it. I guess you are a residential building.

6. If all communication fails, it is necessary to fight back against the scum with poor quality: get a vibration motor, and Taobao searches for "vibration motor, anti-noise upstairs super 100W vibration motor counterattack artifact", which is only over 300, which will have unexpected effects.
