Huang Chao then moved into the Tang palace and declared himself the emperor of a new state of Qi. He made his wife Lady Cao empress, while making Shang Rang, Zhao Zhang (), and the Tang officials Cui Qiu () and Yang Xigu () chancellors. Huang initially tried to simply take over the Tang imperial mandate, as he ordered that the Tang imperial officials of the fourth rank or lower (in Tang's nine-rank system) continue to remain in office, as long as they showed submission by registering with Zhao, removing only the third-rank or above officials. The Tang officials who would not submit were executed en masse. Huang also tried to persuade Tang generals throughout the circuits to submit to him, and a good number of them, including Zhuge Shuang () (whom he made the military governor of Heyang Circuit (河陽, headquartered in modern Jiaozuo, Henan)), Wang Jingwu the military governor of Pinglu Circuit (平盧, headquartered in modern Weifang, Shandong), Wang Chongrong (whom he made the military governor of Hezhong Circuit (河中, headquartered in modern Yuncheng, Shanxi), and Zhou Ji (whom he made the military governor of Zhongwu Circuit) — although each of those generals eventually redeclared loyalty to Tang and disavowed Qi allegiances. He also tried to persuade the former Tang chancellor Zheng Tian, the military governor of nearby Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi), to submit, but Zheng resisted, and when he sent Shang and Wang Bo () to try to capture Fengxiang, Zheng defeated Qi forces that he sent in spring 881.
