`Guàirén` is a culturally significant term because it reflects the strong emphasis on social harmony (和谐, héxié) and collectivism in traditional and modern Chinese society. Behaving in a way that is predictable and in line with group norms is often valued, while standing out too much can be seen as disruptive or awkward. To be labeled a `guàirén` is therefore not just an observation of quirkiness but often a social judgment. It implies a failure or unwillingness to conform. This contrasts with the Western, particularly American, romanticization of the “maverick,” “rebel,” or “eccentric genius.” While a brilliant scientist or artist might be called a `guàirén` in China, the term still carries a heavier weight of social abnormality than “eccentric” does in English. An English speaker might proudly call themselves an “eccentric,” but a Chinese person would be very unlikely to self-identify as a `guàirén` unless they were being self-deprecating or ironic.
`Guàirén` is an informal word used frequently in daily conversation. Its connotation depends heavily on the context and the relationship between the speakers.
