‘荐书’ (jiàn shū) literally combines ‘荐’ (to recommend, nominate) and ‘书’ (book, letter, or document), meaning a formal written letter that recommends someone for a position, program, or opportunity. It is commonly used in academic, professional, and official contexts—such as university admissions, job applications, or scholarship reviews—and carries significant weight because it reflects the recommender’s credibility and judgment.

Unlike casual praise, a 荐书 is structured, signed, and often submitted on official letterhead. It typically highlights the candidate’s abilities, character, achievements, and suitability for the target role or program. While similar to English ‘letter of recommendation’, 荐书 implies greater formality and institutional expectation in Chinese contexts—especially when issued by professors, employers, or government-affiliated personnel.
