Liu Chengyou
Later in 950, Liu Chengyou, displeased that the officials Liu Zhiyuan entrusted to were continuing to control the governance, making him feel that he was being ignored, had three of them — Guo's colleague as chief of staff, Yang Bin; the commanding general of the imperial guards, Shi Hongzhao; and the overseer of the financial agencies, Wang Zhang — killed. He also sent secret emissaries to Yedu (鄴都, in modern Handan, Hebei), where Guo Wei was at the time, to kill Guo, but the news leaked, and Guo was able to escape death, although his family members remaining at Kaifeng were killed. Anticipating a reaction from Guo, Liu Chengyou summoned a number of senior generals, including Fu, Gao Xingzhou, Guo Congyi (), Murong Yanchao (Liu Zhiyuan's half-brother), and Xue Huairang () to the capital, apparently hoping that they would support him in a potential operation against Guo Wei. There was no record of how Fu reacted to the summons. Guo Wei quickly advanced south from Yedu to Kaifeng, and when his army encountered the imperial army, the imperial army was crushed. Liu Chengyou was killed in the confusion, and Guo entered the capital. After initially acting as if he was going to support Liu Zhiyuan's adoptive son (and biological nephew) Liu Yun as emperor, Guo seized the throne himself, establishing Later Zhou as its emperor.
