Xiao Jian is an author about whom limited public information is available; neither nationality, dates of birth and death, nor an English name has been clearly recorded. At present, only one work by this author is held in the collection: the science fiction novel Mission of the Sky. Judging from this surviving work, Xiao Jian writes in the science fiction genre, building imaginings around the sky and a sense of mission, a direction fairly common in Chinese science fiction. Owing to the scarcity of relevant material, it is not yet possible to confirm the author's creative history, other works, or literary activities, nor to assess their place and influence within the genre. For readers, Xiao Jian currently appears as a writer remembered for a single work; a fuller understanding of their style must await more works or public information. This introduction is based on the facts in the collection and makes no speculation about the author's life.
