the Left Shence Army camps. Meanwhile, Zhang sat on the imperial throne and dined with Su—fulfilling Su's prophecy—but then realized what disaster he had brought on himself. He tried to flee, but by that time, Kang and the Right Shence Army () officer Shang Guozhong () had arrived at the palace. They attacked and killed Zhang, Su, and most of their followers; the surviving followers hid in the imperial gardens, but were found the next day. Emperor Jingzong did not return to the palace until the following day, and it was said that the officials and the public were all shocked and, for some time, unaware where the emperor was. Meanwhile, Emperor Jingzong appeared to appreciate various advice for him to change his behavior, often rewarding those who offered such advice (including the future chancellors Wei Chuhou and Li Deyu), but did not seem to change his behavior. He also was often spending time with eunuchs and servants, not attending to the affairs of state. The chancellor Niu Sengru, feeling that he could do nothing in this political climate, resigned and went out of the capital to serve as a military governor (Jiedushi). Emperor Jingzong's association with the eunuchs was so close that, in 825, when Cui Fa () the magistrate of Hu County (鄠縣, in modern Xi'an, Shaanxi), on report of a disturbance, arrested some of the people involved in the disturbance—who turned out to be eunuchs—Emperor Jingzong took the arrest personally, had Cui arrested, and refused to have Cui released even after a general pardon had been declared; he further either ordered or permitted the eunuchs to batter Cui so severely that he almost died. Only after the chancellor Li Fengji pleaded for Cui—pointing out that Cui's mother, a sister to the former chancellor Wei Guanzhi, was old and ill—did Emperor Jingzong release Cui. One of the few major debates as to policy during Emperor Jingzong's reign occurred in 825, when Liu Wu the military governor of Zhaoyi Circuit (昭義, headquartered in modern Changzhi, Shanxi), died, and in his will requested that his son Liu Congjian be allowed to inherit the circuit. The former chancellor Li Jiang advocated that Emperor Jingzong not allow Liu Congjian to do so and take the circuit back under imperial control. However, Li Fengji and the powerful eunuch Wang Shoucheng disagreed, and eventually, Emperor Jingzong allowed Liu Congjian to inherit the circuit. Meanwhile,
