Many people have the habit of stacking groceries in the corridor. What should we do for our neighbors who have this habit?

1. I don't know how many households are upstairs (vertically). If there aren't many, you can also visit each household and speak politely. Don't say that the other party threw it, but say that the other party, with such a good character, will definitely not do such a thing, and then scold the person who throws garbage. I think if the other party still has some self-esteem, he won't throw it again. Of course, this method takes time and energy.

2. Wait outside with a video camera or camera in hand, and try to capture some scenes of littering upstairs. With evidence in hand, things will be easier.

3. suing the property, which can't be solved, is obviously their dereliction of duty. Of course, you can complain first and then warn, but you can't sue again.

4. Make some placards at the entrance of the building, to the effect that you should not throw garbage from upstairs, but have public morality and the like, which will also help.

5. To expose this incident to TV stations, some TV stations are still interested in this kind of subject matter.
