Qi State: Located in the northern part of Shandong Peninsula, the terrain is good, so it can defend itself. With Guan Zhong's help, Qi became rich. The slogan of respecting the king and resisting foreign countries was put forward, and its hegemony was supported by the Zhou royal family and many vassal States.

Wu: The terrain is good, with the natural barrier of the Yangtze River. This is a corner, so you can defend yourself. The road to hegemony was supported by the Jin and Zhou royal families. Because as far as the generation of the Zhou royal family is concerned, Wu's ancestor is the eldest son at the beginning of the Zhou Dynasty and has a high status.

* * * Similarity: They all established their hegemony in the war against Chu. And the terrain is very good, easy to defend but difficult to attack.

Qi joined forces with the vassal states to fight against Chu, and Chu was forced to yield and admit the hegemony of Qi.

Wu fought against Chu with the support of the enemy State of Jin. The Chu army was thirty thousand, but it was defeated by two hundred and sixty thousand. Once, Chu was destroyed and its capital was occupied. In this case, why doesn't Wu Canru seek hegemony?
