Kang Han is a Chinese popular-science author who writes on Earth and planetary science. Public information about the author is limited: nationality, dates of birth and death, and educational background are not clearly recorded. Three works by Kang Han are held in the collection—The Other Side of the Earth, The Eight Faces of the Earth, and The Unsolved Mysteries of the Earth—all classified as popular science. The titles suggest that Kang Han's writing centers on the Earth itself, addressing its spatial form, its various facets, and the mysteries that remain unresolved, and seeking to present the planet from multiple angles. The works read as knowledge-oriented books for general readers rather than specialized research monographs, using concrete questions to guide the reader and linking geography, geology, and astronomy. Given the limited material, Kang Han's full body of work and personal history cannot be described in detail; these three titles are the main basis on which readers can come to know the author.
