Second, Qi Huangong is ambitious and open-minded. He only supported Gong Zijiu with Guan Zhong at that time, and even almost killed Xiaobai with one arrow, which was later Qi Henggong. When Xiaobai acceded to the throne, he did not kill his former opponent, but listened to Bao Shu's advice, let bygones be bygones, reused Guan Zhong and entrusted him with an important task. This is the grand occasion of Qi's supremacy over other vassal states.
Third, Guan Zhong's outstanding talent, dedication and outstanding feats Guan Zhong seems to have never thought that Qi Heng's guild would reuse him regardless of the past. In the face of Qi Heng's kindness of not killing, he decided to repay Qi Heng with his talent all his life. Facts have proved that Qi Heng's choice is very correct. Under Guan Zhong's rule, Qi's national strength grew day by day, and it soon surpassed other vassal states and became the overlord at that time.
Without Bao Shu's recommendation, if Qi Henggong was a narrow-minded person, or if Guan Zhong didn't have the talent to run the country, the history of Qi would be a different story. These three people were absolutely beautiful figures at that time, and their personality, character, quality and pattern surpassed many people of their contemporaries. Only when these three people came together did Qi enjoy hegemony.
