Sun Ru
In 887, with Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu) embroiled in warfare, with a number of parties contending for it (including Qin Yan, Yang Xingmi, and Qin Zongquan's general Sun Ru), the imperial government, intending to calm the warfare, made Zhu Quanzhong the military governor of Huainan, in addition to Xuanwu. Zhu Quanzhong commissioned Yang, who had by that point captured Huainan's capital Yang Prefecture (), deputy military governor and Li Fan () as acting military governor. Zhu wrote Shi Pu, requesting passage for Li Fan to pass through Ganhua on the way to Huainan, but Shi was resenting the fact that the imperial government gave the post of Huainan's military governorship to Zhu and not to him despite his higher seniority. When Li Fan reached Si Prefecture (泗州, in modern Chuzhou, Anhui), which was part of Ganhua, Shi laid an ambush for him, which Li Fan was only able to escape due to the fervent fighting by the officer escorting him, Guo Yan (). From that point on, the rivalry between Xuanwu and Ganhua became open warfare. (Zhu was ultimately unable to take control of Huainan due to Yang's resistance and Shi's interference.)
