Call the city management to demolish the illegal building.
This you have to see whether the upstairs decoration is before or after you, if it is before, then you have to decorate the wall or not, if there is a property, if it is after the decoration, then you go to the owner upstairs, see if they have a balcony pipe on that wall, if so, it may be their business, then you can find them to let them make a new balcony plumbing, if there is no balcony plumbing, Then you have to look for the property to see if the sewer pipe of the balcony has broken for a long time, so the wall will be like this.
The upstairs should re-waterproof the balcony, test the water, and carry out the next step of the project until it does not leak, and the downstairs should be repaired again.
You can also go to the store to buy a water-based plugging king along the tile every few times, but also its waterproof effect.
