Madam Hou gave birth to twin daughters. Due to the rumor that twins were inauspicious, she intended to keep the eldest legitimate daughter, Su Miaojin, and kill the younger daughter. The younger daughter, Liu Ningxiang, was rescued by Nurse Ji and given to Liu Fang to raise. Eighteen years later, Su Miaojin damaged her fertility due to an abortion before her marriage. Madam Hou forced Liu Ningxiang to marry in her place. Su Miaojin was not a kind person, and Liu Ningxiang was bullied by her. Moreover, because her adoptive father was killed by Su Miaojin, she developed a vengeful heart. After she endured humiliation and became pregnant, she finally succeeded in replacing Su Miaojin, and Su Miaojin was killed by Madam Hou.
