How to solve the problem that high-rise residents throw garbage out of the window and affect the following?

First: move with emotion, understand with reason! As neighbors, you should live in harmony.

Second: find a property. If there is no property, you should complain to the sanitation department. Let the sanitation department cooperate with the community to clean up the garbage. Otherwise, it will only expose these poor people with no quality. Record their ugly behavior with a digital camera and expose it in the media. These people should take them to the streets. Let everyone throw rubbish at them. Let them taste what it's like. Sometimes violence is the only way to solve problems.
