齐桓公
Prince Yukou was close to his cousin Chen Wan, son of Duke Li of Chen, the fifteenth ruler of Chen and Yukou's uncle. Afraid that his life was also in danger, Chen Wan fled to the State of Qi in the northeast. Duke Huan of Qi made Chen Wan an official in charge of manufacturing, and Chen Wan established the Chen (later known as Tian) clan in Qi. The Chen clan of Qi would grow increasingly powerful over the centuries, and eventually usurped the Qi throne.
