"Punning" (yiyu shuangguan) means that a single phrase or sentence has one meaning on the surface while implying another, with both layers of meaning holding true at the same time, and often the second layer is what the speaker really intends to express. This rhetorical device is commonly found in literary creation, everyday banter, diplomatic language, and advertising copy, and it reflects the speaker's wit and subtlety. Its cultural background can be traced back to the traditions of homophony and metaphor in ancient poetry, such as Liu Yuxi's line "The sun rises in the east while rain falls in the west; though one says there is no sunshine, there is sunshine," in which "sunshine" (qing) is homophonous with "feeling" (qing). "Dream of the Red Chamber" makes extensive use of puns, such as "Zhen Yinglian" being homophonous with "truly to be pitied." In terms of emotional coloring, puns can be either positive or negative: in a positive sense, they appear humorous, clever, and tactful; in a negative sense, they may seem slick or insinuating. They are mostly used on occasions where it is inconvenient to speak directly, where taboo avoidance is needed, or where linguistic interest is sought. It should be noted that a pun must allow the listener to grasp the second meaning; otherwise, it loses its effect.
📝 Example
1. He said with a smile, "You're such a busy person that you don't even have time to eat." This remark is a pun, praising my career success while also subtly mocking me for neglecting my friends. (Refers to a sentence containing both praise and sarcasm.)
2. The advertising slogan "Leave early to 'ban' spots, don't 'dou' stay" is a pun, cleverly combining "getting off work" with "removing spots" and "lingering" with "removing acne," leaving a deep impression. (Refers to a sentence that on the surface talks about getting off work and lingering, but actually promotes spot-removing and acne-removing products.)
