Guan Zhong
In 645 BC, as Guan Zhong had fallen seriously ill, Duke Huan consulted him to find a successor to the Chancellorship. When Duke Huan recommended Bao Shuya, Guan Zhong spoke against it, on the grounds that Bao Shuya was too honest, upright and unyielding. Guan Zhong stated that Bao Shuya held himself to very exacting standards, but also expected others to do the same; this meant it would be difficult for him to work with the rest of the court.
