姚兴
Murong Chao was apprehensive that his true identity would be known, and so he became a beggar and pretended to be insane. However, on one occasion, the brother of Later Qin's emperor Yao Xing, Yao Shao (姚紹) the Duke of Dongping, saw him, and thought that this was not truly an insane person—because he looked healthy and strong physically. He informed Yao Xing of this and suggested that Yao Xing give Murong Chao a minor official position to secure him. Yao Xing summoned Murong Chao to an audience with him, but Murong Chao continued the charade and intentionally gave wrong answers or no answers at all when Yao Xing asked him questions. Yao Xing was unconvinced that Yao Shao was correct, and so sent Murong Chao away.
