Confucius advocated that "rites and music should be conquered by the emperor", and all the people who violated the rites were accused. Qi Huangong dominated under the banner of "respecting the king", and Confucius thought that his practice was in line with the rules of propriety. With Guan Zhong's assistance, Qi Huangong's "nine-in-one", "one-in-one" and "respecting the king and resisting foreigners" led the vassal states to repel the foreign invasion of China, avoided the fate of the destruction of the Central Plains culture, and created a rare situation of stability and unity in the Central Plains since Zhou's reunification. In other words, Confucius believes that Qi Huangong's hegemony has made great contributions to the preservation and continuation of Chinese culture.
