Li Zhengji
In 781, Li Baochen the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) died, and his son Li Weiyue wished to inherit his position. Emperor Daizong's son and successor Emperor Dezong refused to grant imperial sanction. In light of this, Li Weiyue prepared for war against the imperial government, and Li Zhengji, Tian Yue (Tian Chengsi's nephew and successor), and Liang Chongyi the military governor of Shannan East Circuit (山南東道, headquartered in modern Xiangfan, Hubei), who had made an alliance to support each other in attempts to be able to pass their circuits to their descendants, prepared for war as well. After Li Zhengji himself died later in 781, Li Na initially kept his death a secret but, pursuant to the alliance, sent troops to aid Tian and Li Weiyue. In fall 781, he announced his father's death and requested to succeed Li Zhengji. Emperor Dezong denied his request as well.
