Su Tang lives on the sixth floor. Because her mother has difficulty moving her legs, she paid 230,000 out of her own pocket to install an elevator in the building. The neighbors took it for granted and used it for free for three years. It wasn't until Sister Wang moved in and reported Su Tang five times for piling up cabinets at her doorway, while the neighbors also used hallway safety as an excuse to make Su Tang clear away the cabinets. Only then did Su Tang see clearly that her kindness had been treated as being easy to bully. She shut down the elevator and stopped outputting meaningless kindness. Sister Wang regrets it, but it is too late.
