Later in 544, Gao Cheng, wanting to stamp out corruption within the imperial administration, empowered Cui Xian and Song Youdao (宋遊道) to investigate high-level officials for corruption. Cui and Song each made several accusations against high-level officials, and Gao Cheng had, in particular, Sima Ziru stripped of all titles and offices, and Yuan Tan (元坦) the Prince of Xianyang stripped of his offices. In order to show that Cui, in particular, was empowered to carry out investigations, Gao Cheng had Cui intentionally show disrespect to himself in public with impunity, so that the officials would be even more apprehensive of Cui.
