Notes on Maintenance of Old Buildings

Chen Yan is a building builder. Pipes, circuits, walls, whatever is broken should be repaired. Until he dug out a pinhole mark from twenty-seven years ago in the crack in the wall of Building No. 7. Built into the wall of this building is an account that no one dares to acknowledge: steel that was cut, names that were erased, and a death that was written as an "accident." The old resident is tight-lipped. The filing cabinet of the old man has been locked for twenty-seven years, and no one dares to open it. Chen Yan repaired room after room, asking seam after seam. During the day he repairs buildings. At night, he repaired the hearts and minds of the people this building owed. The building will grow old, but the accounts will not.
