Koreans at the end of the Warring States Period (now Xinzheng, Henan). The original text is from "Everything is done by Han Feizi. The Foreign Reserve is Left"

Original: Some Chu people sold their pearls to Zheng, which were Mulan's cabinets, smoked with cinnamon, decorated with pearls and jade, decorated with roses, decorated with feathers and breastplates. Zheng Guoren bought the jewelry box and returned the pearls. This can be said to be a best seller, but it is not a good pearl. "

There was a businessman in the State of Chu who sold jewelry in the State of Zheng. He carved a pearl box with precious Mulan, smoked it with spices made of cinnamon, and decorated it with jewels and jadeite. A man from Zheng bought this box, but returned the beads in it to him. It can be said that this jeweler is good at selling boxes, but not at selling jewelry!

Revelation: It is ridiculous that Zheng people only pay attention to the appearance but not to the inside. The lack of attention of Chu people also makes them afraid to sell pearls. Tell us to proceed from reality.
