《资治通鉴·后周纪·后周纪二》
原李守贞的骑士马全随郭荣入朝，后周太祖召见他，补授他为殿前指挥使，对左右的人说： 马全忠于所服务的主人，从前在河中时，屡次挫败我的军队，你们应该仿效他。 
故李守贞骑士马全乂从荣入朝，帝召见，补殿前指挥使，谓左右曰： 全乂忠于所事，昔在河中，屡挫吾军，汝辈宜效之。 
Li Shouzhen's former cavalryman, Ma Quan, followed Guo Rong to attend court, and the Emperor Taizu of the Later Zhou summoned him, making him the Commanding Officer of the Imperial Guard, and said to the people on his left and right: "Ma Quan was loyal to the masters he served, and in the past when he was at Hezhong, he repeatedly frustrated my army; you should imitate him."
