Guan Zhong, also known as Yi Wu, is a clever man. When he was young, he often interacted with Bao and knew that he was talented. Guan Zhong was born in a poor family and often cheated Bao Shu, but Bao Shu always treated him well and kept his secret. Later, he served the son of Qi, and Guan Zhong served Gong Zijiu. When Xiaobai was made Duke Huan, Gong Zijiu was killed and Guan Zhong was imprisoned. Bao Shu recommended Guan Zhong to Huan Gong. After Guan Zhong was hired, he was in charge of Qi State, which led to Qi Huangong's hegemony, meeting with governors and saving the world for many times. All these were Guan Zhong's strategies.
