Vice Minister of the Court of Judicial Review, son of Grand Secretary Zhou Chongtai. One of Yanjing's most famous young nobles. Named after the verse 'One string, one pillar, thinking of glorious years' because his mother died in difficult childbirth. As a child he was frail and sickly but possessed extraordinary talent for solving criminal cases. The common people claimed he was the reincarnation of Judge Bao. He is one of the Third Prince's trusted subordinates, and his chronic illness improved largely because Yan Huaijin searched for famous physicians for him. He frequently gathers with Yan Huaijin and Pei Yunting to discuss current affairs and criminal cases.
