The first is that the king of Zhou has no ability to restrain them. During the Spring and Autumn Period, the strength of each vassal state was different. Many countries have carried out reforms in order to become stronger, such as the Guanzhong reform of Qi, which has made Qi's strength grow rapidly. For other countries, they began to covet. There is still a gap in the combat effectiveness of Zhou Wang's army. If Zhou Huan had a strong army, he wouldn't be bullied by Zheng Zhuanggong. Therefore, the king of Zhou in the Spring and Autumn Period was really incapable of managing this matter.
The second is that other people's flags are very good. The main slogan of Qi Huangong's crusade against other countries is to respect the king and resist foreign countries. This slogan moved the royal family of Zhou very much, and there were still many governors who supported it. Therefore, when the Kwai Chung Alliance was held, the Zhou royal family sent people to attend and recognized the hegemony. This is also a good example, that is, as long as there is a reasonable slogan, you can go to war with foreign countries.
The third is that the reform effect of Zhou royal family is too poor. At first, the reform failed because of local opposition, and then another reform was carried out because ethnic minorities failed to go south, and then no reform was carried out because people were divided. There is only one thing that can be used by the Zhou royal family, and that is the title. The advantage of doing this is to ensure that your position will not be taken away, and another function is to avoid being affected.
The Zhou royal family can only give Fang Bo the title at this time. After the Warring States period, the sense of existence of the Zhou royal family was even smaller. What would you do if you were the monarch of the Zhou royal family?
