唐僖宗
By 884, Huang had been defeated and killed, but Qin, who then controlled Fengguo Circuit (奉國, headquartered in modern Zhumadian, Henan) as its military governor ("Jiedushi"), then became a rebel himself against Emperor Xizong of Tang. As of late 884, Qin was sending a number of his officers to attack or seize territory around his. As part of Qin's campaigns, Sun seized Luoyang, Meng Prefecture (孟州, in modern Jiaozuo, Henan), Shan Prefecture (陝州, in modern Sanmenxia, Henan), and Guo Prefecture (虢州, in modern Sanmenxia). In summer 885, however, he was again battling the Tang defender of Luoyang, Li Hanzhi, for control of Luoyang. It was said that while Li initially abandoned Luoyang after running out of food supplies, Sun only occupied Luoyang for about a month, before burning the palaces, government offices, and houses, and leaving Luoyang after plundering it, allowing Li to again occupy Luoyang.
