Su Jianguo wins 30 million in the lottery, netting 24 million after taxes. Keeping it a secret from everyone, he pretends to ask about eldercare to test his two sons. His eldest son, Su Ming, is a city CEO whose wife and he consider his parents a burden and refuse to care for them on the spot. His younger son, Su Qiang, is a farmer 4.6 million in debt, yet takes his parents in without hesitation. Su Jianguo tests Su Qiang three times—buying medicine, keeping night watch, and selling land—and Su Qiang and his wife pass each test with true devotion. Once the truth comes out, Su Ming and his wife demand 25 million and sue, only to lose and divorce. Su Ming kneels in remorse, and Fang Qing atones by working on a construction site before they remarry. The 30 million is split three ways, and a 'Su Family Road' is paved.
