周济
As of 881, the major agrarian rebel Huang Chao had captured the Tang capital Chang'an, forcing then-reigning Emperor Xizong to flee to Chengdu. Zhongwu's then-military governor Zhou Ji initially submitted to Huang, who established a new state of Qi as its emperor, but at the urging by the eunuch general Yang Fuguang redeclared allegiance to Tang in summer 881. Yang took 8,000 Zhongwu troops and organized them into eight corps, commanded by Lu Yanhong, Jin Hui (), Wang Jian, Han Jian, Zhang Zao (), Li Shitai (), and Pang Cong () respectively. He then took the troops northwest to join the other Tang troops in campaign against Huang.
