Song Tang has married into the Chen family for four years. All household expenses, big and small—the mortgage, utilities, and children's tuition—are borne entirely by her alone. Her father-in-law, Chen Guoliang, holds a pension but only cares about his own enjoyment, unwilling to subsidize household expenses by a single penny, and even pounds the table in public insisting on dividing the family. Feeling thoroughly chilled, Song Tang readily agrees on the spot, turning around to stop paying all household expenses. The Chen family, having lost Song Tang's support, instantly falls into a predicament; various bills expire one after another, and conflicts erupt centrally. Only then does the family see clearly that it has always been Song Tang bitterly supporting the home, and their past harshness turns entirely to regret, but Song Tang has long resolved to withdraw and no longer carry a heavy load for this selfish family.
