刘志军
In summer 891, Zhu Quanzhong's officer Ding Hui put Su Prefecture under siege. Zhang Yun surrendered to Ding in winter 891, and Shi Pu's officer Liu Zhijun subsequently surrendered to Zhu Quanzhong as well. It was said that Liu's surrender dealt a heavy blow to Shi Pu's army, which was not able to recover from it.
