Guan Zhong
Though an able administrator in his own right, Bao is best known for his friendship with Guan, and for persuading Duke Huan of Qi to put aside personal enmities and elevate Guan Zhong to the post of Chancellor. As an official he was renowned as a judge of character and talent, with Guan Zhong himself commenting that "My parents gave birth to me, but it is Bao who knows me best."
