Ma Yin
In 923, Later Liang was conquered by Later Tang. Ma Yin submitted to Later Tang as a vassal, and sent Ma Xifan to the Later Tang capital Luoyang to offer tributes. The Later Tang emperor Li Cunxu, both because he was impressed by Ma Xifan's alertness and intelligence, and because he wanted to try to alienate Ma Yin's trust in his chief strategist Gao Yu, made the comment, "I had long heard that the Ma state would be seized by Gao Yu. With a son like you, how could Gao steal the state?" (Ma Yin, however, was not swayed by this comment, and continued to trust Gao, although Gao would eventually be killed by Ma Xisheng in 929.)
