New daughter-in-law Pei Yun marries into the Shen family, only to encounter antiquated and bad customs where the women of the household can only eat standing up and are not allowed to sit at the table together. Facing the old rules passed down through generations from their ancestors, she refuses to compromise, bringing a chair to break the imprisonment. She argues with reason, tears off the disguise of old concepts, awakens her long-enduring mother-in-law, and drives her family to re-examine household chores and family division of labor. Starting from a single chair at the dinner table, she rewrites the family's getting-along mode little by little. The old customs are slowly dismantled, women fight for an equal seat at the dining table, and the family finally understands how to sympathize with each other, achieving a truly equal and warm family life.
