The Zhao family has a thirty-year-old custom that tortures people: before dinner, the daughter-in-law Li Guifen must respectfully invite grandmother Zhou Shulan six times, and only then can the whole family touch their chopsticks, with the dishes often turning cold. The granddaughter-in-law He Huanhuan, with a straightforward personality, after marrying into the oppressive Zhao family, cannot stand this kind of blind filial etiquette, pities her wronged mother-in-law, and bravely faces the bad custom head-on. Under her influence, her cowardly husband Zhao Lei learns to protect his wife, and the fence-sitting father-in-law Zhao Zhigang also has a sudden awakening. Huanhuan slowly understands that grandmother's adherence to old rules stems from the protection of her grandfather during his lifetime for fear that she would be left out in the cold. The family unties years of knot in their hearts, the aunt who lost contact for ten years returns home, the absurd old customs are abolished, the family members show consideration for each other, and they reap true family warmth.
