He Jianmin once lent three million to his brother Cheng Zhenyu, but twenty years later the other party flatly denied it. Because his son's school admission urgently needed tuition fees, He Jianmin took his wife and child to demand a debt and suffered humiliation. Afterward, his wife was cheated on buying a house, and He Jianmin, with the help of lawyers and reporters, collected evidence, exposed real estate fraud, and recovered the losses. Finally, he bought a second-hand house, made up for the debt to his wife, and regained the dignity and warmth of his family.
