Lu Wu is a young author about whom limited public information is available; the writing currently traceable to this name falls mainly within the field of youth literature. The representative work is On Second-Rate Geniuses, the only title by Lu Wu included in our collection. Judging from the title and its category, the book may center on self-perception, talent, and personal positioning during adolescence, carrying the coming-of-age narratives and emotional concerns common to youth literature. Because Lu Wu's nationality, dates of birth and death, educational background, and writing career are not clearly documented, this introduction relies only on the work itself and its category, without speculating about the author's personal life. On the available evidence, Lu Wu's writing is still at the stage of presenting a personal style through a single work, and On Second-Rate Geniuses is the main entry point for understanding this author's creative profile; further public materials are needed to shed light on future work.
