李正己
Li Weiyue thus prepared for war against the imperial government, along with several military governors who were also ruling their circuits semi-independently and who had previously entered into alliances with Li Baochen — Li Zhengji the military governor of Pinglu Circuit (平盧, headquartered in modern Tai'an, Shandong), Tian Yue the military governor of Weibo Circuit (魏博, headquartered in modern Handan, Hebei), and Liang Chongyi the military governor of Shannan East Circuit (山南東道, headquartered in modern Xiangfan, Hubei). Li Baochen's secretary Shao Zhen (邵真), hearing of these plans, tearfully begged Li Weiyue to reconsider, and suggested that he arrest Li Zhengji's messengers and deliver them to Chang'an, believing that by doing so, Li Weiyue might gain sufficient imperial trust that his request might be accepted. The secretary general Bi Hua (畢華), however, argued that the imperial government might still not trust Li Weiyue anyway, and if Li Zhengji then attacked, Chengde would be defenseless, and Li Weiyue agreed with Bi. Li Weiyue's uncle Gu Congzheng (古從政) also opposed resisting the imperial government; he suggested that Li Weiyue should leave Li Weicheng temporarily in charge of the circuit and personally head to Chang'an to pay homage to Emperor Dezong in order to gain imperial trust. Li Weiyue refused, and Gu committed suicide. Subsequently, Tian sent his officer Meng You (孟祐), along with 5,000 soldiers, north to aid Li Weiyue in defense of Chengde, while he himself launched preemptive attacks on Zhaoyi Circuit (昭義, headquartered in Changzhi, Shanxi), then controlled by the imperial general Li Baozhen.
