Duke Ding of Qi
Duke Ding of Qi, personal name Lü Ji, was the second recorded ruler of the Qi state.
According to classical Chinese texts such as the Records of the Grand Historian and Zuo Zhuan, Duke Ding succeeded his father, Duke Tai, who was said to have been a centenarian. Duke Ding supposedly served King Kang of Zhou along with other major vassal state rulers including Xiong Yi, Count Kang of Wey, Ji Xiefu and Bo Qin. However, most modern historians believe Duke Ding was in fact the fifth-generation descendant of Duke Tai, and he could not have served King Kang of Zhou.
After Duke Ding died, he was succeeded by his son, Duke Yi.
