踉踉跄跄 is a four-character reduplicated expression that vividly describes walking in an unsteady, stumbling manner — as if you're about to fall because you're drunk, exhausted, or injured. It appears in literary or descriptive Chinese, usually as an adverbial or predicate (e.g. 走得∼ 'walks staggering'). Unlike the English 'stagger about,' it emphasizes the visual wobbly motion step by step.
