Duke Xi of Qi (Chinese: 齊僖公; pinyin: Qí Xī Gōng), personal name Lü Lufu, was from 730 BC to 698 BC the ruler of the Qi state.
Duke Zhuang of the State of Zheng sent Crown Prince Hu (later Duke Zhao of Zheng) to help Qi repel the Northern Rong.
[1][2] Duke Xi reigned for 33 years and died in 698 BC.
Wuzhi himself was also killed soon afterward, and Duke Xi's younger son Xiaobai ascended the throne, posthumously known as Duke Huan of Qi.
Qi grew strong under Duke Huan's rule and he became the first of the Five Hegemons of the Spring and Autumn period.
