Zhu Ci
In fall 783, JIngyuan soldiers, then at Chang'an to be ready for deployment against the rebels in the east, mutinied when they were angry they did not get rewards. Emperor Dezong was forced to flee to Fengtian (奉天, in modern Xianyang), while the Jingyuan soldiers supported Zhu Ci as their leader, and Zhu Ci soon declared himself emperor of a new state of Qin. Upon the news arriving in the imperial camp at Wei Prefecture, Ma, Li Baozhen, and Li Qiu () withdrew to their own circuits, while Li Huaiguang, under the suggestion of his logistics officer Cui Zong (), decided to march as quickly as he could toward Chang'an to save Emperor Dezong. By the time that Li Huaiguang arrived in Chang'an's vicinity, Fengtian was under intense siege by Qin troops under Zhu Ci. Li Huaiguang sent his officer Zhang Shao () to Fengtian to inform Emperor Dezong of his impending arrival, and then attacked Qin forces at Liquan (醴泉, in modern Xianyang) and defeated them. When Zhu Ci heard the news, he, in fear, lifted the siege on Fengtian and withdrew back to Chang'an. It was believed at the time that Li Huaiguang arrived right on time and that, if he were even three days late, Fengtian would have fallen. After the victory, Emperor Dezong gave Li Huaiguang the title of "Zhongshu Ling" () — the head of the legislative bureau of government (中書省, "Zhongshu Sheng") and a post considered one for a chancellor.
