Take Qi State as an example to explain how it grew up.

Qi is an ancient vassal state, and the first monarch was Jiang Ziya. It can be said that from the beginning, Qi's position was relatively high, occupying a certain height politically and militarily. Later, the growth of Qi was not unrelated to the enlightenment of Qi monarch. Qi Huangong reused Guan Zhong, making him the first tyrant in the Spring and Autumn Period. The good names of Qi Huangong and Guan Zhong are immortal. In the Tianqi era, Qi Weiwang, who was eager for talents, established Jixia Academy, which was a center of academic culture at that time. In the last years of Qi Weiwang, Qi became the most powerful country among the vassal states.
