People upstairs throw all the rubbish into my balcony. How can I talk in the property group?

It can be said: hello, everyone. For the safety of all owners, please don't throw garbage at high altitude. Please put it in the trash can. Thank you for your cooperation.

The analysis is as follows: 1, talk to neighbors face to face about the seriousness of the matter, and have responsibilities and obligations with each other. If it doesn't make sense, go directly to the property. After all the above methods are completed, you can get the evidence and find a lawyer to sue the other party for throwing objects at high altitude. 2. When talking face to face with neighbors, be emotional, don't get excited, and tell each other the harm of the incident with emotion and reason. If the other person's personal quality is really low, it is unreasonable. After a period of time, I still threw garbage, so I went to the property to solve it, but after the property, I still couldn't solve the fundamental problem. It is necessary to take action to install camera devices in the garbage dump of neighbors in order to grasp the evidence and sue each other.
