Male, Deputy Minister of the Dali Court in his early twenties. Handsome and radiating righteousness. He first met Su Yihan four years ago during the Cheng Building Dismemberment case when he was seventeen. He became her secret-keeper after she threatened him, and later became her admirer and half-mentor in detective work. He is fair and impartial, refusing to bend the law for personal reasons. He often writes letters to Su Yihan though she rarely replies. He feels envious of Shen Yu's closeness with Su Yihan.
