Liu Wanfu is a Chinese author of legal books. Publicly available information about him is limited, and the only confirmed work is Legal Practice Across the World (Lü Xing Tianxia). The book is classified under law, and judging from its title and category, it likely deals with legal practice and the application of rules, aimed at general readers and practitioners who wish to understand how the law operates. Since no reliable records of the author's life, nationality, education, or professional background are available, this profile makes no inferences and relies solely on the work information in the database. Books that popularize law generally require clear expression and orderly structure, translating abstract rules into concrete situations so that readers can follow them step by step. Liu Wanfu's work offers a reference sample among books of this kind, and its influence remains to be assessed with more materials and reader feedback.
