Liu Chengyou
When the Later Han emperor Liu Chengyou killed Guo Wei's entire family remaining in the capital Kaifeng, he also sent agents to assassinate both Guo and Wang Jun. When the plot failed, Guo and Wang rebelled and led the troops to attack Kaifeng. Once Liu was killed, Guo was in charge of the affairs of the state, and he asked the empress dowager to appoint Wang as the commissioner of military affairs (樞密使).
