《战国策·秦三·应侯曰郑人谓玉未理者》
天下的君王还照样尊敬他，这是天下的君王不如郑国商人聪明，被名声所迷惑，而不了解他的实质的缘故。 
天下之王尚犹尊之，是天下之王不如郑贾之智也，眩于名，不知其实也。 
The kings of the world still respect him. This is because the kings of the world are not as smart as the merchant from Zheng. They are deceived by his reputation and do not understand his true nature.
