Jia Su
Meanwhile, the mayor of Jingzhao, Jia Su, was a political enemy of Li Deyu's and friendly with Li Zongmin and Zheng. At an imperial feast, Jia was supposed to get off his horse and bow to the imperial censors, but Jia refused to do so. The junior censors Yang Jian () and Su Te () pointed this out and argued with him, and when he cursed them, submitted an accusation against Jia. As a result, Jia was given a fine. Jia, humiliated, initially requested an assignment outside the capital, but before he could depart, Emperor Wenzong promoted Jia to be chancellor. (According to comments by the modern historian Bo Yang, this commission was Zheng's way of showing that he had the power to make people chancellors.)
