Zhou Jianguo, a 58-year-old veteran worker at Yuanshan Heavy Industries, is rehired after retirement. He hands over his entire monthly salary of 28,000 to his wife, Lin Guilan, while single-handedly bearing the family's living expenses and all of his stepson's loans. A watch he saved up to buy frugally is ruthlessly smashed in public by his stepson, yet the family turns facts upside down and accuses him of selfishness. Exhausted by twenty years of forbearance, Zhou Jianguo decisively cuts his losses and divorces. Armed with ledger books, bank statements, and audio recordings, he forcefully beats back his wife and son's unreasonable entanglement and property schemes. Relying on his company's official vindication to stand firm, he successfully safeguards his property and dignity, living out a carefree and independent new life in his later years.
