The Wronged Retired Matriarch

Helen Chen moves into son's home. For three years, she receives a monthly 3000 yuan allowance, does all tasks, subsidizing expenses with her Pension. A remark from the Co-mother-in-law leads her son and daughter-in-law to suspect money hiding, demanding Pension records. Disheartened, Helen Chen returns the 3000 yuan and stops all housework. Only when the family takes over, lives descend into chaos, and accounts are cross-checked, do they discover the truth.
