Liu He is an author about whom limited public information is available. Only one work by this author can currently be identified, namely Intelligent Systems, which is commonly categorized under artificial intelligence. Since information such as dates of birth and death, nationality, and educational background is not found in the available records, his personal history cannot be described in detail. Judging from the subject matter of the work, however, Liu He's writing focuses on the principles, composition, and applications of intelligent systems, placing it within Chinese-language writing on artificial intelligence. The title points directly to the technical core, suggesting that the author intends to discuss the overall framework of intelligent systems rather than confine himself to a single algorithm or specific product. On the basis of the available material, this book is the only clue to Liu He's direction as a writer; its style tends toward conceptual organization and knowledge introduction, making it suitable as a basic text for understanding artificial intelligence systems. Given these limitations, further public information is still needed regarding the author's academic background, research interests, and writing trajectory.
