Yu Fan
Yu Fan was later nominated as a "maocai" (茂才; an outstanding civil servant). The Han central government in Xu (許; present-day Xuchang, Henan) offered him a position to be an Imperial Clerk (侍御史) but he declined the offer. The warlord Cao Cao, who then held the nominal appointment of Minister of Works (司空) even though he controlled the central government, also wanted to recruit Yu Fan to serve in his office. When Yu Fan heard about it, he rejected Cao Cao's offer and remarked, "The robber Zhi wishes to use his excess wealth to corrupt good people."
