The neighbors downstairs installed smoke exhaust pipes on the balcony privately, instead of taking the original flue, which was smoking every day. It's no use looking for a property report. What should I do? The property has absolute responsibility for this matter. Neighbors downstairs installed it on the balcony, which destroyed the original structure of the community. Property can not be ignored, but must be coordinated. If the property shirks its responsibility, you can consult a lawyer to sue the property and negotiate directly with the property manager. Decoration management is within the scope of the property, and maintaining the original structure and overall image of the community is also within the scope of property responsibility.
