Zhou Zhenshan, the eldest son of the Zhou family, dropped out of school at fifteen to repair cars and support his younger brother through school and into marriage, while squeezing into a cluttered storage room with a leaking roof himself. When the old street was redeveloped, his father gave all the compensation money and the resettlement apartment to the younger son, offering Zhenshan only twenty yuan. Heartbroken, Zhenshan married into the Xu family in a neighboring county. His younger brother received the apartment and money but could not manage his life: renovation work leaked, a faulty car he bought injured someone, he framed his elder brother, and he was dismissed for falsifying his work history and fell into debt. Meanwhile, Zhenshan relied on his real abilities in the Xu family's transport team, introduced preventive maintenance, and rose to become the operations manager of transport fleets across five counties. When his parents cleaned out the old house, they finally admitted their mistakes after seeing the mold stains, the red bricks used to prop up a bed, and the suppressed school admission notice. His younger brother began hauling goods in a warehouse to repay his debts, and each family member finally took responsibility for their own life.
