Qi Huangong was the first country to establish hegemony in the early Spring and Autumn Period. Qi Huangong appointed a politician Guan Zhong to reform its internal affairs, and made full use of coastal conditions to develop fishery and salt industry, which made huge profits. Another 30 thousand standing soldiers were trained, and Qi became rich and strong. Put forward the slogan of "respecting the king and rejecting the foreign countries", organized vassal States under the guise of respecting the emperor, defeated the good harmony and saved Yan; Defeated the Di nationality and saved Xing Hewei; In addition, he mobilized the masses and stopped Chu's northward advance with aggressive military actions. Qi Xianggong held several meetings with the governors, and Zhou Wang also sent people to join the alliance, giving them chariots and flags, thus acknowledging his hegemony. After the death of Guan Zhong and Qi Huangong, Qi was in civil strife and its national strength was weak, but it still maintained its status as a great eastern country.
After Qi Huangong's death, Song Xianggong longed for hegemony. He and Chu fought a battle on the flood bank, and they had already arranged their positions. Sima Yuzi wanted Song Xianggong to attack when the Chu army crossed the river, but he didn't agree. Later, Yu Zi proposed that the Chu army land. He was waiting in line and marching in the chaos, but he still didn't agree. In this way, fighter planes were lost again and again, and finally Song Jun was defeated, and Song Xianggong's guards were completely annihilated, and he was also seriously injured. Ironically, after he was defeated on the battlefield, he also published a fallacy, saying that the teacher of benevolence and righteousness "didn't catch twenty cents". If the enemy was injured, he should not be allowed to suffer for the second time ... This fallacy that led to failure has become an eternal joke.
Qi Huangong's hegemony is truly inherited by Jin Wengong. At that time, the king of Zhou was in chaos, and the prince led the United Dickens to drive away the king of Zhou Xiang. Jin Wengong took advantage of the situation, once again playing the banner of "respecting the king and rejecting foreign countries", met with the governors, defeated Wang Zidai, and escorted King Xiang of Zhou to return to China for reset. Then, in the name of saving the Song Dynasty, the joint forces of Jin, Song, Qi and Qin were organized to launch a crusade against the invading troops of Chu, Chen and Cai. This is the famous battle of Chengpu. Before the decisive battle, 8 Jin Army took the initiative to "retreat from three houses". When the Chu army pursued, the Jin army returned to attack and won a great victory. Jin Wengong was a vassal of the Congress, accepted the appointment of the Zhou Emperor, became the overlord, and gained more prominent power than Qi Huangong. The hegemony of the state of Jin lasted for one hundred years.
Qin was a small country in the Western Zhou Dynasty. After Dong moved to the capital, his power gradually developed. When Qin Mugong wanted to develop eastward, it was hindered by the powerful state of Jin, so it had to turn to attack the small country of Rongdi in the west, wiped out a dozen small countries and became the regional hegemon in the west.
When Qi Jin dominated, Chu, located in the Yangtze River and Hanshui River valley, often went north to compete with Qi Jin for hegemony. When Chu Zhuangwang was in power, he reorganized his internal affairs and built water conservancy projects, which wiped out many small countries and made his power stronger. On one occasion, the State of Chu drove the army to the border of the Zhou Emperor and asked him how heavy Jiuding, a symbol of kingship, was, suggesting that Jiuding should be taken away to take the place of the Zhou Emperor. Defeated Jin Jun in the Battle of Shao. Since then, Chu Jin's hegemony has won and lost, so some small countries have to pay tribute to these two countries at the same time and admit that they are both hegemonic.
