After four years of marriage, she was kicked out of the 18-person family group by her mother on the grounds that there were "too many people." She was shocked to find that her three married sisters, the eldest sister, the second sister, and her cousin, were also treated in the same way. However, the group kept her married daughter-in-law, unmarried sister-in-law, and even her grandmother's empty mobile phone number. For thirty years, she and her sisters worked as her parents' cash machine and paid silently, but they were not as close as a mobile phone number. After seeing clearly the truth that her family favored sons over daughters and treated her married daughter as an outsider, she stopped being a "sensible" daughter and decisively set boundaries, refusing to pay without a bottom line. Even if she was criticized, she would firmly protect her own life.
