Liu Fang marries into the Zhao family, where her mother-in-law Li Guilian is overbearing and domineering, secretly rummaging through belongings, causing trouble at a birthday banquet, forging debts, and embezzling savings. After conflicts escalate, the household officially splits, leaving Liu Fang and her husband with only a dilapidated house and a barren fish pond. Seeing the potential in the pond, Liu Fang and her husband repair it and raise fish. Li Guilian repeatedly creates obstacles—scooping up fish fry, pouring soapy water, threatening to cut off power, and illegally wiring electricity to cause a pond disaster. Liu Fang stays dutiful, pays monthly maintenance, and manages the fish pond to prosperity through hard work and wisdom. Ultimately, Li Guilian admits her mistake, the two households remain separated, family affection returns, and the family sits together for a meal.
