"Neither fish nor fowl" is a commonly used derogatory idiom, used to describe something that belongs neither to one category nor another—that is, it is unstandardized, unseemly, and dubious. It emphasizes that something has lost its proper categorical belonging and harmony, appearing incongruous and ridiculous. This idiom comes from Cao Xueqin's Dream of the Red Chamber in the Qing Dynasty, where it is used in the novel to criticize certain people or things as improper and incongruous. In terms of usage scenarios, it is often used to describe people's clothing and appearance, speech and behavior, literary and artistic works, architectural styles, and so on—for example, an odd-looking mix of Chinese and Western dress, or a piece of writing that mixes genres and lacks a unified style. In terms of emotional coloring, it carries a clear tone of mockery and criticism, with a relatively strong tone, though it can sometimes also be used for self-deprecation. In terms of cultural background, it reflects the emphasis in traditional Chinese culture on "having a proper name and justified status" and on being appropriate and fitting. Things should conform to their proper categories and norms; otherwise, they will be regarded as neither fish nor fowl.
