《世说新语·容止》
中书令裴楷容貌俊美。有一次生了病，非常疲乏，晋惠帝派王夷甫去看望他。这时裴楷正向着墙躺着，听说王夷甫奉命来到，就勉强回过头来看看他。
名士传曰： 楷病困，诏遣黄门郎王夷甫省之，楷回眸属夷甫云： 竟未相识。 
Zhongshu Ling Pei Kai was handsome. Once he fell ill and was very tired. Emperor Jin Huidi sent Wang Yifu to visit him. At this time, Pei Kai was lying facing the wall. When he heard that Wang Yifu had been ordered to come, he turned his head back to look at him with difficulty.
