Liu Ruilin is an author about whom limited public information is available. One work by this author is currently held in the collection, titled Life on the Blade. In terms of common classification, the book falls under design, suggesting that Liu's writing concerns objects, craft, and design culture rather than fiction or purely theoretical writing. The word "blade" in the title hints that the work may deal with knives, cutting tools, or the related skills of making and using them, and further with the relationship between people and objects, craft and everyday life. Given the limited material, it is not possible to confirm Liu Ruilin's nationality, dates of birth and death, educational background, or other publications, nor whether the author has long been engaged in design research or craft practice. On the basis of the available information, Liu may be regarded as a writer who takes design as a subject and attends to specific objects and craft details. Life on the Blade, as the representative work, is the main entry point for understanding the author's writing orientation, through which readers can observe how Liu approaches everyday implements to discuss the experience, skill, and humanistic meaning behind design.
