Elevator Renovation? Not My Business on the First Floor

Elevator Renovation? Not My Business on the First Floor Plot:

Aunt Li, a first-floor resident, thinks elevator renovation only concerns upper floors and refuses to sign the consent form. After repeated communication fails, the property halts the project. One day, Aunt Li gets trapped in the dark corridor without her keys and realizes the renovation delay caused her predicament—if completed earlier, the old elevator would have been replaced. Ashamed and scared, Aunt Li contacts the property and persuades other residents to cooperate, warming the whole community with this small corridor incident.
