Original text:

Some Chu people sold their pearls to Zheng, that is, Mulan's cabinet, decorated with cinnamon, pearls and jadeite, decorated with roses, decorated with feather clothes and jadeite. 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.

Translation:

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!
