It was Zheng who bought jewelry in the process of buying bamboo slips and pearls. There was a jeweler in the state of Chu who went to Zheng to sell jewelry. In order to get a good price, he carved a box with incense wood and tried his best to decorate it beautifully. Then put the ball in. One of Zheng's people liked this beautiful box very much and bought it at a high price. He opened the box and returned the jewels to the jeweler, leaving only the box. This box is so well made.

The implication of buying bamboo slips and returning pearls.

Modern times are used as a metaphor for spending a lot of capital, but getting little in return. People who sell rafters get pearls on rafters. Describe people who are short-sighted and make improper choices. Beauty can be created, but real beauty should not be artificially carved. It should be a blooming flower in the real world. If something is really beautiful, then it doesn't need any outside help to set it off. Don't pay too much attention to appearance. The essence is the most important thing.
