《战国策·齐四·齐人有冯谖者》
又过了不久，冯谖又弹着他的剑，唱道： 长剑呀，我们还是回去吧，出门没有车坐。 孟尝君说： 替他配上车，待遇和其他门客一样。 
于是乘其车，揭其剑，过其友曰： 孟尝君客我。 
After a short while, Feng Xuan strummed his sword again and sang: My sword, let's go home, there is no carriage to ride when I go out. Meng Changjun said: get him a carriage, and treat him like the other guests.
