Supervising Secretary of the Directorate of Ceremonial, a eunuch castrated at age fourteen. Young, thin, and sharp-tongued, he rose quickly among palace eunuchs and court officials. He believes Zhang Yao wielded the knife that saved his life during a treason case involving the former Crown Prince, and constantly speaks of repaying this imaginary favor. He jokes casually about his castration and has a fond, bickering relationship with Zhang Yao.
