At sixty-two, Li Xiuyun has been retired for ten years. She appears to be a gentle country grandmother, but in reality, she holds a doctorate in linguistics from Oxford University and is the true power behind Great Deeds International. For ten years, she has silently devoted herself to caring for her son Zhang Wei's household, only to be looked down upon and insulted by her daughter-in-law Zhao Juan and granddaughter Tingting. When her granddaughter publicly calls her "stupid" in English, Li Xiuyun finally awakens. Using legal means, she reclaims her assets and exposes her daughter-in-law's family's illegal activities, defending her dignity. After enduring betrayal, conspiracies, and family conflicts, she not only rebuilds her family relationships and guides her granddaughter's growth but also finds devoted protection from Shen Yu, a former student of hers.
