1. The war between the Duke of Song Huan and the State of Zheng and the State of Chu
After the alliance between Juandi, Zheng Guo and Song Guo fought for two consecutive years, and finally Zheng Guo and Song Guo made peace, and allied with Qi, Lu, Chen, and Wei in Youdi. In the sixteenth year, the State of Chu attacked the State of Zheng, so Song, Qi, and Lu rescued the State of Zheng. In the twenty-third year, because Zheng Guo was close to the State of Qi, the State of Chu attacked Zheng Guo again, song, Lu, Qi, and Zheng allied with Zheng guo, and planned to rescue Zheng Guo.
Subsequently, The Duke of Song Huan and the State of Qi and other princes met and plotted to attack the State of Chu. In the twenty-sixth year, the Duke of Qi Huan and the princely states of Song, Lu, Chen, Wei, and Zheng attacked the State of Cai, and the State of Cai was defeated and took the opportunity to attack the State of Chu. In the twenty-seventh year, Duke Huan of Song and the various princely states met with Ji Zheng, the crown prince of King Hui of Zhou, to stabilize the Zhou royal family.

In the thirtieth year, Song Huan and the envoys of the Zhou royal family, lu guo, qi guo, Wei guo, Xu guo, Cao guo, and Zheng guo, once again met in Taodi to discuss how to stabilize the Zhou royal family. Soon, Duke Huan of Song fell seriously ill, and Crown Prince Zifu requested that his brother Muyi succeed to the throne.
Duke Huan of Song agreed, but Muyi pushed xie and said, "Is there any greater benevolence than this in ceding the throne of the country to others?" I am inferior to him, and I do not conform to the order of the monarchs. "In the thirty-first year, Duke Huan of Song died, and Crown Prince Zipu succeeded to the throne as Duke Xiang of Song.
2. Song Xianggong helped Duke Xiao of Qi ascend the throne
After Song Xianggong succeeded to the throne, he took Muyi as the xiangguo, in charge of military affairs, and assisted in the government. Soon, Song Xianggong went to the Kuiqiu Huimeng, and during the alliance, the Duke of Qi Huan entrusted the Prince of Qi to Song Xianggong, and Song Xianggong also promised to take care of Prince Zhao.
Later, Duke Huan of Qi became seriously ill, and the five princes of the State of Qi competed for the throne, and Prince Zhao of Qi fled to the State of Song, and Duke Xiang of Song fulfilled his original promise to help Crown Prince Zhao return to the State of Qi and take the throne. The following year, Duke Xiang of Song sent a notice to the princely states, asking them to jointly escort Gongzi Zhao back to the State of Qi to ascend the throne.
However, the princes did not take the Song Kingdom seriously, and only Wei, Cao, and Yi responded to the call of Song Xianggong. Song Xianggong led the four kingdoms to attack the state of Qi, and the princes and nobles of the state of Qi were very sympathetic to Prince Zhao, and they welcomed Prince Zhao back to China at Linzi, and he was the Duke of Qi. Song Xianggong also became a bit famous for taking advantage of this.
