The word 复原 is formed by combining two meaningful characters: 复, which carries the idea of "returning", "repeating", or "restoring", and 原, which means "original", "primary", or "source". Their combination creates a direct, conceptual compound where the action of the first character (to return/restore) is directed toward the state or object of the second (the original condition), thus visually and semantically representing the process of returning something to its former or undamaged state, i.e., "to restore" or "to rehabilitate".
