Buying gifts and returning pearls, an ancient idiom in China, comes from Han Feizi. The original intention is to buy jewelry and leave only beautiful boxes, without real high-value jewelry. Often used as a metaphor for lack of foresight and improper choice.

Explanation of words: wooden box; Pearl: Pearl. Bought a business box and returned the pearls. Metaphor is a person who has no vision, improper choice, and only pays attention to appearance but not substance. It also satirizes those who don't understand the essence of things, abandon the roots and pursue the end, and abandon the Lord for the second time.

Han Fei (280- 233 BC), a philosopher at the end of the Warring States Period, was the main representative of Legalism, and he wrote Han Fei's On Han Feizi's Left Foreign Reserve.
