On his way, he runs into his biological daughter and son-in-law, but they look down on him for being shabby and dirty. Heartbroken, he decides to pretend to be poor to test their family affection. He travels to the city to seek refuge with his daughter, only to be treated as an embarrassing burden. They give him just 500 yuan and send him back to his hometown, with the couple even insisting that his adopted daughter should be responsible for looking after him in his old age. His adopted daughter, He Xiaojuan, is genuinely devoted to him. She uses all her savings to repay his fictitious debts and takes loving care of him day and night. Later, when his biological daughter hears about the enormous demolition compensation, she immediately comes to visit and pretends to be filial.
