This work contains AI-generated content. For the elevator installation in Building Number Six, eleven out of twelve households signed, leaving only Zhou Yan, the electrician on the first floor. Lin Wan, the grid worker, went to his door time and again, only to be pushed back by his remark that this building cannot be installed with one. She went upstairs with him to knock on the wall: brick-concrete from 1992, the shaft pressing on three structural columns, with a budget of six hundred thousand and not a single penny for reinforcement. She paid for the appraisal out of pocket, and he shelled out six thousand. On the day they finished signing, Aunt Wang walked downstairs by herself for the very first time.
