Lei Chenxi is an author about whom little public information is available; the library currently holds only one work by this name, the history book The Legend of Kung Fu. Judging from this surviving clue, Lei Chenxi's writing touches on historical subjects and takes "kung fu," a theme with a distinct cultural identity, as its point of entry, addressing readers interested in the history of martial arts and traditional culture. The Legend of Kung Fu is classified as a history book, suggesting that its approach leans toward organizing historical material and cultural narration rather than fiction. Because no clear record exists of the author's biography, nationality, education, or writing career, this introduction makes no speculation and sketches the author's profile solely on the basis of the work held in the library. As far as the available material goes, Lei Chenxi's writing has yet to be presented through more works and public information; readers may come to know the author's narrative approach and focus on this subject through The Legend of Kung Fu.
