In late 546, Gao Huan became seriously ill, and he summoned Gao Cheng back to Jinyang to entrust the matters to him. At that time, Gao Cheng was apprehensive that the general Hou Jing, who commanded the provinces south of the Yellow River, would rebel, and Gao Huan left him a list of officials that he could trust, and specifically instructed him to make Murong Shaozong (慕容紹宗) the commander of the army against Hou if Hou rebelled. Gao Huan died in spring 547, but Gao Cheng, also pursuant to Gao Huan's instructions, did not announce Gao Huan's death in public; rather, he returned to Yecheng, pretending that Gao Huan was still alive.
