Recently, I moved, and changed to a high-rise elevator house. I was second-hand house in a mature community. I was not satisfied with the original decoration, so I spent more than two months to redecorate the old house. I must say hello to the upper and lower floors. I used to go there before. I said it was a young couple at the opposite door. I was a little older brother downstairs, about fifty years old. I said that I had leaked water. When I was doing the bathroom waterproofing, because the supervisor came home during the holidays, I asked me to go downstairs to ask if it was leaking. One day, I checked the water level at my own house. I should have no problem and went downstairs to knock on the door.
