Zhao Jun is a Chinese author whose work mainly falls into mystery and social fiction. Public information about him is limited: his nationality, dates of birth and death, educational background, and writing career are not clearly documented. According to the available records, two of his works have been catalogued, Gray Eyes and Exposing the Person Behind It. Though few in number, they show a sustained commitment to the mystery genre. Judging from the titles and categories, his works tend to revolve around puzzles, investigations, and the revelation of truth, blending a mystery framework with observations of social reality so that the people and human nature behind each case become the narrative focus. This gives the books both the readability of genre fiction and the realistic concern of social fiction. Since information about the author himself remains scarce, readers can still come to know Zhao Jun mainly through these two works, sensing his writing orientation and stylistic aims in the unfolding of plot and the portrayal of character.
