李靖
Early in 944, Li Bian's son and successor Li Jing wrote to both Wang Xi and Wang Yanzheng to rebuke them for their intrafamily family war. Wang Xi's return letter to Li Jing cited the examples of the Duke of Zhou's executions of his brothers the Lords of Guan and Cai and Emperor Taizong's killing of his brothers Li Jiancheng and Li Yuanji. Wang Yanzheng's return letter to Li Jing, however, was more confrontational, rebuking Li Jing's father Li Bian for usurping the throne of Southern Tang's predecessor state Wu. In anger, Li Jing cut off relations with Yin.
