Legal issues: sue the property company and demand compensation for housing losses.

Your situation is that the property maintenance is not timely. Evidence: the property didn't go in time, so I went to the office to do the on-site notarization of the existing blisters and the damage certificate of the wooden floor. Loss: the loss appraisal of damaged blisters (price certification center under the local price bureau), and the amount of compensation according to the certified price. The above is ready, go to court to sue.
