The moral and truth of buying bamboo slips and returning pearls: Zheng people only stare at exquisite wooden boxes and give up precious jewels. It can be seen that things must be clearly defined, and people who buy gifts and return pearls can't just pay attention to the appearance of things without seeing the essence of things. Only by seeing the essence of things clearly and prioritizing can we make appropriate choices.

There is a Chu man who sells jewelry in the state of Zheng. He carved a pearl box with precious Mulan, smoked it with cinnamon pepper, decorated it with jewels and jewels, connected it with beautiful jade, decorated it with jade and connected it with kingfisher feathers. 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 good at selling jewelry.

In the story, Zheng people only pay attention to the appearance and ignore the essence, which makes him make an inappropriate choice. The "over-packaging" of the Chu people is really ridiculous. The story of this idiom tells us: we should prioritize our work, and we should not give up everything and make improper choices.
