When Duke Lu Ding succeeded to the throne, Zhao Jianzi asked Shi Mo if Ji would die? Shi Mo said, "No." Because the Ji clan has done great deeds for the Lu state, generations have meritorious deeds. After the death of Duke Wen of Lu, the State of Lu killed Li Shu and the monarch of the State of Lu lost power.
Power is in the hands of the Ji clan, for four generations. The people of the Country of Lu do not know their monarch, can such a monarch rule the country? Those who are monarchs must abide by ceremonial instruments and titles, and cannot give them to others.
In the fifth year of Lu Dinggong, Ji Pingzi died. Yang Hu imprisoned Ji Huanzi because of his personal grudge, and later Ji Huanzi made a pact with him, and he released Ji Huanzi. In the seventh year, the State of Qi conquered Yunyi, and Yang Hu lived in Yunyi and made Yunyi his own Fengyi, where he handled government affairs.
In the eighth year, Yang Hu wanted to get rid of the concubines of the Sanhuan family and establish a concubine who had a good relationship with him. So Yang Hu sent a car to pick up Ji Huanzi to kill him, and Ji Huanzi used a trick to escape. Then the three Huans attacked Yang Hu, and Yang Hu ran to Yang Guan.
In the ninth year, the State of Lu sent an army to attack Yang Hu, who ran to the State of Qi and then fled to the jurisdiction of the Zhao clan of the Jin State. In the tenth year, Lu Dinggong and Qi Jinggong met in the valley, and Confucius presided over the ceremony.
The State of Qi wanted to attack Lu Dinggong, confucius rebuked the State of Qi according to etiquette, qi Jinggong was afraid, did not dare to harm Lu Dinggong, and returned the encroached Land of Wenyang in the State of Lu to apologize.
After that, Lu Dinggong trusted Confucius and made him the Grand Sikou and was responsible for domestic security. Confucius finally got the opportunity to pursue his political ideas, emphasizing filial piety, stabilizing the family, and stabilizing society.
It will make the country harmonious, the economy prosperous, and the country rich and the people strong. In the twelfth year, Lu Guo sent Zhongyou to demolish the walls of the Sanhuan family and confiscate their armor and weapons. Meng refused to demolish the city wall, and Lu Dinggong sent troops to attack him, but was unable to defeat him.
When the State of Qi heard that Confucius had governed the State of Lu well, he was afraid that the State of Lu would threaten the State of Qi, so he designed to frame the State of Lu, and the State of Qi gave many beautiful women and horses to the State of Lu, and Ji Huanzi accepted the beauties and horses of the State of Qi, causing Lu Ding to ignore the government, and Confucius was forced to leave the State of Lu and begin to travel around the world.
In the fifteenth year, Duke Lu Ding died, and his son would succeed him, the Duke of Lu Ai.
