The Earl of Zheng requested to abandon the sacrifices to Mount Tai and instead offer sacrifices to the Duke of Zhou, exchanging the territory of Bing near Mount Tai for the fields of Xu. In the third month, the Earl of Zheng sent Wan to return Bing, indicating that he would no longer sacrifice to Mount Tai.
In summer, Duke Ji Fu of Guo began serving as a minister in the royal court of Zhou.
In the fourth month, on the day of Jiachen, Prince Hu of Zheng went to Chen to marry his wife, the Lady Gui. On the day of Xinhai, he returned with the Lady Gui. On the day of Jiayin, they entered Zheng. Chen's Zhen Zi escorted the bride. Prince Hu first consummated the marriage with his wife and only then performed the ancestral temple announcement. Zhen Zi said: "This is not a proper marriage. He has deceived his ancestors. It is contrary to ritual propriety. How can he produce descendants?"
The people of Qi ultimately mediated relations between Song, Wei, and Zheng. In autumn, they met at Wen and formed an alliance at Wawu, thereby settling the old grievances from the Battle of the Eastern Gate. This was in accordance with ritual propriety.
In the eighth month, on the day of Bingxu, the Earl of Zheng led the people of Qi to have an audience with the King of Zhou. This was in accordance with ritual propriety.
The Duke Yin of Lu formed an alliance with the people of Ju at Fulai, in order to achieve friendly relations with Ji.
In winter, the Marquis of Qi sent an envoy to report the resolution of the conflict among the three states. The Duke Yin sent Zhong Zhong to reply, saying: "Your lordship has eliminated the enmity among the three states and brought peace to their people. This is your lordship's grace. Our humble ruler has received the command; how would he dare not to accept your lordship's bright virtue?"
Wu Hai died. Yu Fu requested a posthumous title and a clan designation for him. The Duke Yin asked Zhong Zhong about clan designations. Zhong Zhong replied: "The Son of Heaven establishes those of virtue, granting them a surname based on their birthplace, enfeoffing them with lands and bestowing a clan designation. The feudal lords use the character of their posthumous titles and make this their clan designation. If an officer has hereditary merit, he may have an official clan designation; the same applies to fiefs." The Duke Yin ordered that Wu Hai's character be used as his clan designation, which became the Zhan clan.
