The Chinese word **退伍 (tuìwǔ)**, meaning "to be demobilized from the military" or "to retire from active service," is a compound word formed through a logical verb-object grammatical structure. It combines the character **退 (tuì)**, which means "to retreat," "to withdraw," or "to step back," with **伍 (wǔ)**, an ancient term for a military squad or ranks, now meaning "armed forces" or "company." Thus, the term literally and conceptually means "to withdraw from the ranks," where the action of leaving (**退**) is directly applied to the object, the military unit (**伍**), efficiently encapsulating the idea of a service member's formal departure from active duty.
