《后汉书·列传·马援列传》
公孙述拥着皇帝用的銮旗和旄骑，左右侍卫之人全都像皇帝一样上车，屈身如磬而入，掌管仪礼和宴会的官员都很多，想授予马援以封侯大将军爵位。
述鸾旗旄骑，警跸就车，磬折而入，礼飨官属甚盛，欲授援以封侯大将军位。
Gongsunshu held the emperor's ceremonial flags and mao riders in his hands, and all the attendants on the left and right got into the car like the emperor, bending their bodies like a chime and entering. There were many officials in charge of etiquette and banquets, and they wanted to grant Ma Yuan the title of Marquis and General.
