齐康公 / Duke Kang of Qi
齐康公 / Duke Kang of Qi appears in Zhouji 09 as the last Jiang-line ruler of 齐国. The source says he dies without an heir during the broader early Warring States war period.
The episode uses his death as an old-order endpoint. Jiang-line Qi had already lost practical control to the Tian family; with Qi Kang Gong’s death, the source treats the older lineage as fully ended while Tian-family Qi continues through Tian-family Qi Huan Gong and 田英齐.
