Why is Song Xianggong one of the five tyrants in the Spring and Autumn Period?

He once presided over the governors' league. After the death of Qi Huangong, the hegemony of Qi ceased to exist, and Song Xianggong wanted to inherit Zhou Shi, a vassal of Meng Hui, Qi Huangong. However, Song was only a medium vassal state with weak national strength. However, Song Xianggong can rely on two things. First, he has always advocated benevolence and righteousness, won the support of the Chinese people, and has a good reputation among the governors, which is regarded as a highly respected person;

The title of Song State is nobility. Because Song was a vassal state made by the descendants of the Shang royal family, it ranked first among the "Five Kings" and one of the best vassal states in the Central Plains. Even the State of Qi is just a marquis. Others, such as the marquis of Jin, Yan Bo, Qin Bo, Zi Chu, etc. all follow the etiquette of the Zhou Dynasty and command the governors as dukes.

After Qi Huangong's death, the hegemonic position became vacant. Song Xianggong wants to follow Qi Huangong's example, meet the governors and establish hegemony. Mu Yi remonstrated with him and said, "It is a disaster to meet a vassal with the strength of a small country." Xianggong didn't listen.

In the 11th year of King Xiang of Zhou (64 BC1year), Teng was detained, Cao and Zhu were invited to join the alliance in the south of Cao, and later Zhu Wengong was ordered to go to the outskirts of Suishui as a sacrifice, hoping to threaten the submission of Dongyi. In the autumn of the same year, Song Xianggong sent troops to surround Cao, because Cao refused to obey.

In the winter of the same year, Chen Mugong invited the princes to rebuild, so Chen, Cai, Chu, Zheng and other countries formed an alliance in Qi. In this way, it became two big groups among the princes. Countries such as Chu, Qi, Zheng, Chen and Cai were one big group, while only a few small countries such as Wei, Zhu, Cao and Slippery attempted to dominate.
