《礼记·玉藻》
对于国君所赐的车马和衣服，在行过再拜礼之后，如果国君没有再下可以乘、服的命令，臣下就不敢乘、服，只能收藏起来。
膳于君，有荤桃茢，于大夫去茢，于士去荤，皆造于膳宰。
Regarding the chariots and clothes bestowed by the emperor, after performing the proper bows, if the emperor does not give further orders to ride or wear them, the ministers should not dare to do so, but should only store them away.
