Luo Yueju: little is known about his life, official career, or dates of birth and death, and available public information is limited; all that is currently known is that a single work, Xianbin Lu (Records of Guests from Afar), survives under his name. The book belongs to the social sciences and concerns contacts between China and foreign lands and accounts of distant regions, recording local customs, products, and tribute exchanges abroad. It is an important reference for understanding Sino-foreign relations and overseas geographical knowledge in the Ming period. The author writes in a plain style, prizing factual record over elaboration, and arranges materials by category for easy consultation. Given the scarcity of sources, the circumstances of composition, the process of compilation, and the author's circle of acquaintances are difficult to verify, and scholarly study of the book has focused mainly on its documentary value and the provenance of its materials. Overall, Luo Yueju is known for a single notebook-style work that preserves valuable information about foreign lands and holds irreplaceable documentary significance.
