召忽 / Shao Hu
召忽 / Shao Hu enters the wiki through 《资治通鉴·周纪》75-2丨“穷奢极侈”的祖师爷管仲 as the defeated 公子纠 loyalist who dies after the succession struggle. The episode contrasts him with 管仲, who had also served Gongzi Jiu but lives and accepts appointment from 齐桓公.
The source does not turn Shao Hu into a simple foil for disloyalty. Its point is that different choices produce different historical visibility: Shao Hu becomes a brief example of old-master loyalty, while Guan Zhong’s survival lets his capacity reshape 齐国.
