神策军
There was a most unusual disturbance occurring at the capital Chang'an, three months after Emperor Jingzong ascended the throne. The fortune teller Su Xuanming () and the imperial textile servant Zhang Shao () were friendly with each other, and Su informed Zhang that he saw, in Zhang's future, that he would sit on the imperial throne and dine with Su. Su pointed out to Zhang that because Emperor Jingzong spent his days hunting and playing games the palace would often lack security. Zhang gathered his fellow servants and street hoodlums and on a day when Emperor Jingzong was playing polo at Qingsi Hall (), Zhang and Su launched their attack on the palace. Emperor Jingzong, in panic, fled the palace to the camps of the Left Shence Army (), commanded by the eunuch Ma Cunliang (). Ma protected Emperor Jingzong and sent his officer Kang Yiquan () with an army to the palace to secure it. Cavalry soldiers were also dispatched to escort Grand Empress Dowager Guo and Empress Wang to 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.
