劉知遠
After Liu Zhiyuan entered Kaifeng, he commissioned Wang Jinchong as a general of the imperial guards, but was not impressed by Wang at that point. He did not have Wang accompany him when, shortly after, Du Chongwei the military governor of Tianxiong Circuit (天雄, headquartered in modern Handan, Hebei), rose and resisted him and he then attacked Tianxiong's capital Yedu () in response. Wang, however, volunteered to deliver the reports of the defender of Kaifeng (apparently, Liu's son Liu Chengxun ()) to Liu Zhiyuan's camp. When he met Liu Zhiyuan to deliver the reports, he requested that he be allowed to remain in the imperial army and participate in the siege of Yedu. He also made many tactical proposals to Liu Zhiyuan and argued persuasively for his proposals, impressing Liu Zhiyuan.
