Xu Jianguo and Shen Lanzhi, married for thirty-six years, suddenly propose a divorce. Their daughter Xu Zhixia, who works as a wedding planner, finds it unacceptable. Under her insistence, the family of three sets a thirty-day divorce practice period—living in separate rooms with separate accounts and independent lives. From cooking and sorting medicine to paying bills and arranging repairs, from a dispute over a clay pot to an eighty-thousand-yuan loan, this elderly couple truly sees each other for the first time during the practice, and re-understands the meanings of marriage, family, and love.
