Lu Jiajun: publicly available information is limited. What can be confirmed is mainly that he appears in the Chinese book market as a writer of popular science. The library holds one work by him, Enhancing Humans, which is classified under popular science. Judging from this work, Lu Jiajun's writing focuses on the relationship between the extension of human capacities and technological development, and he attempts to turn frontier scientific concepts into content that general readers can readily understand, which places his work within popular-science writing aimed at a broad audience. Because the author's nationality, dates of birth and death, educational background, and professional experience are not clearly documented, this introduction makes no inferences about his personal life and presents his writing only on the basis of the subject and classification of his work. For readers who wish to learn about popular-science topics related to human enhancement, this book can serve as an introductory text; a fuller picture of the author awaits further public information.
