As a female censor, the legitimate daughter of the Su family is an upright official and dedicated to protecting her family. Sister Su Zhiruo married into the Hou family. On the surface, she is stoic, gentle and generous, but in fact she is deeply involved in internal disputes. Her husband wanted to marry another person, and there was an undercurrent of competition for the title of his heirs. She repeatedly used the power of her mother's family to benefit herself, but she later shied away from it, causing harm to her family. Everyone in the Su family has gone through worldly events and seen clearly the authenticity of human feelings, and no longer blindly condone them. With sobriety and wisdom, the legitimate daughter quietly observes the turmoil in the house, sticks to her true intentions, protects her parents' safety, distinguishes right from wrong, and maintains the peace and integrity of the family in the midst of numerous disputes.
