Yan He is an author about whom relatively limited public information is currently available; only one work by this author, the social novel Metaphor, is included in the collection. Since basic details such as the English name, nationality, and dates of birth and death are not clearly recorded, no account of the author's personal background can be given at present. Judging from the social-fiction category to which Metaphor belongs, Yan He's writing appears to focus on social reality and to present the relationship between individuals and their environment through fictional narrative. The title Metaphor itself carries rhetorical and symbolic connotations, perhaps suggesting that, beyond realism, the work also embodies a deeper level of observation. On the basis of the available material, Yan He's creative profile remains incomplete, and the stylistic features and literary influence of this author await further works and commentary. Readers approaching Metaphor may note how social themes are selected and from what narrative angle they are presented, which is currently the most direct clue to understanding this author.
