Ci's rebellion In fall 783, soldiers from Jingyuan Circuit (涇原, headquartered in modern Pingliang, Gansu), at Chang'an to await deployment to the east, mutinied after not receiving awards that they believed they deserved. Emperor Dezong fled to Fengtian (奉天, in modern Xianyang, Shaanxi), initially taking only his family members and a small group of eunuchs and imperial guards with him. Lu and fellow chancellor Guan Bo, in the confusion, had to jump over the walls of the office of chancellors, located at the legislative bureau (中書省, Zhongshu Sheng), to catch up with Emperor Dezong. Emperor Dezong issued emergency edicts seeking aid from the nearby circuits. Meanwhile, the Jingyuan soldiers supported Zhu Tao's brother Zhu Ci, who had been removed from his command in 782 due to Zhu Tao's rebellion, as their leader. Zhu Ci initially claimed that he was merely calming the situation at Chang'an and was ready to welcome Emperor Dezong back to Chang'an, but soon there were rumors that Zhu was planning to claim imperial title himself and attack Emperor Dezong at Fengtian. In light of this, some officials who had fled to Fengtian suggested that Fengtian's defenses be shored up, but Lu, misjudging the situation, argued to Emperor Dezong that Zhu would surely remain faithful to Tang and advocated taking no precautions at all and stopping the incoming aid troops, although at Jiang Gongfu's advice Emperor Dezong continued to receive the aid troops into Fengtian. At suggestion of Lu and Bai Zhizhen (白志貞) the commander of the imperial guards, Emperor Dezong sent his granduncle Wu Xu (吳漵) (Emperor Daizong's mother's brother) to Chang'an to communicate with Zhu. Zhu initially welcomed Wu as an honored imperial emissary, but soon put Wu to death. He declared himself emperor of a new state of Qin. Meanwhile, the official Cui Ning arrived at Fengtian several days after Emperor Dezong did. Emperor Dezong was pleased, but Lu heard that, on the way to Fengtian, Cui had made comments that Lu was responsible for misleading the emperor into this disaster. Lu feared that Cui would accuse him of causing the calamity, and therefore secretly plotted with an official who had arrived at Fengitan with Cui, Wang Hong (王翃). He had Wang make a secret report to Emperor Dezong that on the way to Fengtian, Cui had frequently stopped to defecate or urinate and appeared to be waiting for Zhu's soldiers. Lu and Wang
