Background:
Five tyrants in the Spring and Autumn Period came to power. The five tyrants are Qi Huangong, Jin Wengong, Song Xianggong, Qin Mugong and Chu Zhuangwang, and the first one is Qi Huangong. Qi became the largest country in the Spring and Autumn Period, not only because of its good geographical location and advantages in fishing and salt, but also because of its profound cultural heritage and high-quality cultivation of its citizens.
Jiang Taigong helped King Wu unify the world and was sealed in Qi. The culture developed by his family represents the traditional Taoist culture. Duke Zhou was sealed in Lu, and the Zhou family preserved the humanistic culture of the Zhou Dynasty and developed the Confucian culture of later generations. Therefore, the word Qilu culture is useful for later generations, and it is called China traditional culture.
In Huan Gong Kuang He, Kuang is rectification, and he is convergence. Qi Huangong corrected the chaos in the world and joined different governors. In The Analects of Confucius, it was recorded that "Duke Huan and nine kings ruled the world together" and nine governors' conferences were held. Like the current United Nations General Assembly, he is the Secretary-General, and makes a covenant with the vassal states.
Qi Huangong didn't talk empty words. He made a northern expedition to save Yan, pacify the emperor and help Xing, once solved the disaster of Zhou royal family and made Zhou Xiang king. In 656 BC, Eight-Nation Alliance, led by Lu and Song, conquered Chu in the south, forcing Chu to enter into a covenant to prevent Chu from advancing northward. In his 43 years in office, Qi Huangong rectified the governors 26 times, which really helped the weak and helped the poor.
