Gao Xingzhou
During the "Changxing" era (930-933) of the Later Tang emperor Li Siyuan, An Chongrong served as a military commander at Zhenwu (which was then headquartered in modern Shuozhou). He had once committed an offense and was imprisoned, and then-military governor ("Jiedushi") of Zhenwu, Gao Xingzhou, wanted to put him to death. An Chongrong's mother went to the Later Tang imperial government, then located at Luoyang, to appeal for his life. Li Siyuan's chief of staff An Chonghui protected An Chongrong, and An Chongrong was not put to death. It was not known what the aftermaths of that incident exactly were, but apparently at some point An Chongrong was free and became an officer at Zhenwu again.
