‘装订’ (zhuāng dìng) refers to the physical process of binding loose pages or sheets into a finished book or document — such as stitching, gluing, stapling, or perfect binding. The character 装 (zhuāng) means 'to install', 'to fit', or 'to assemble', while 订 (dìng) means 'to fasten', 'to secure', or 'to order'. Together, they convey the idea of assembling and securing pages into a durable, organized format. It is commonly used in publishing, printing, office work, and academic settings — for example, when preparing thesis copies, creating reports, or restoring old books.

This term emphasizes the mechanical or craft-based aspect of bookmaking, not digital formatting or editing. It can function as both a noun (e.g., ‘the binding is sturdy’) and a verb (e.g., ‘we’ll bind it tomorrow’). While often associated with traditional paper books, it also applies to pamphlets, manuals, and even some high-end notebooks. It does not refer to cover design or typesetting — only the structural joining of content.
