She is the legitimate daughter of a declining scholarly family. Her father was originally an imperial censor. He was framed for impeaching a powerful official and was relegated to the frontier before he died of illness. The family became the laughing stock of the capital. Mother and daughter depended on each other and lived in the house of a distant uncle. He looks gentle and gentle, but in fact he is thoughtful, forbearing and tenacious. He is proficient in chess (taught by his father and regards it as a metaphor for "games in the world"), calligraphy, and medical skills (taught by himself to take care of his sick mother). He has strong observation skills and is good at capturing key information from details.
Growth arc: In order to protect himself and clear his father's wrong, he carefully deals with all forces; in the middle stage, he gradually reveals his strategy, using chess pieces to break the deadlock and get rid of dependence; in the later stage, he becomes a key figure who can influence the situation of the court, not only avenging blood, but also protecting the people he wants to protect, and finally chooses to "retire after success" and live his life.
