The article discusses how the meaning of the phrase "wu suo wei" has evolved over time in Chinese language. Originally, it meant "there isn't the thing that people talk about", but now it is used to imply something not worth mentioning.

This change has led to a reanalysis of its structure, turning it from a transitional phrase into a single word.
