What about hanging clothes upstairs and dripping water?

1. If clothes drip upstairs, partition them, especially the balcony. Don't let the dripping water hit the clothes directly.

2, get a partition in the position where clothes are hanging, and discuss with the people upstairs to let them improve.

3. If people upstairs have difficulty communicating and don't listen to suggestions, they can complain to the property or help coordinate through the neighborhood committee.
