Subsidizing six thousand every month, Chen Ning picked up and dropped off her older brother and sister-in-law's children and handled household chores, yet when her daughter ate a single chicken drumstick, her sister-in-law recorded it as twelve yuan in the ledger.

Facing continuous urging, emotional pressure, and the torn-up growth album, she no longer backed down, calculating every contribution clear piece by piece, and guarded her daughter's dignity. Until her brother and sister-in-law personally bore the cost of childcare, her brother finally admitted that he had always known how much grievance his younger sister had suffered.
