Xu Keqiong (許可瓊) was a general of the Chinese Five Dynasties and Ten Kingdoms Period state Chu.
[1] As of 950, Chu was torn by a civil war, as then-prince Ma Xiguang was facing the challenge to his rule by his older brother Ma Xi'e the military governor (Jiedushi) of Wuping Circuit (武平, headquartered in modern Changde, Hunan).
I, Xu Keqiong, and my family have been serving as Chu generals for generations, and will surely not disappoint you.
Xu, without letting his soldiers know, met with Ma Xi'e and continued negotiating with him, finally agreeing to his terms.
Ma Xiguang's other infantry commander, Wu Hong (吳宏), and Yang Di (楊滌), fought hard to try to resist the Wuping army's assault from the early morning to noon, but eventually, Yang's army was worn out, without any aid coming from either Xu or another commander Liu Yantao (劉彥瑫).
[2] Ma Xi'e, after his victory, neither carried out his promise to Xu Keqiong (to divide Chu among them) nor gave him any particular rewards.
Xu thereafter arrived at Gui and defeated Peng in battle; Peng abandoned Gui and fled to Hengshan (衡山, in modern Hengyang, Hunan), where Ma Xi'e was at that time after being overthrown by another brother, Ma Xichong.
[4] However, with Xu having abandoned Meng, the Southern Han general Wu Huai'en (吳懷恩) seized it and proceeded to approach Jingjiang's capital Gui Prefecture (桂州), pillaging the circuit at will.
