According to classical Chinese texts such as the Records of the Grand Historian and Zuo Zhuan, Duke Ding succeeded his father Lü Shang, Duke Tai of Qi, 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, viscount of Chu, Count Kang of Wey (衞康伯), Xie, Marquis of Jin and Boqin, Duke of Lu. 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.[3]

After Duke Ding died, he was succeeded by his son Duke Yǐ of Qi.[1][2]
