'Dǎng lù' literally combines 'dǎng' (to block, obstruct) and 'lù' (road, way), forming a verb meaning 'to block the way' or 'to get in someone’s path.' It describes physical obstruction — such as a person, object, or animal standing where others need to pass — and often carries a mildly negative or inconvenient connotation. The phrase is commonly used in everyday spoken and written Chinese to express impeded movement or progress.

This compound is typically used intransitively or with a direct object indicating who or what is being blocked (e.g., '挡了我的路'). It does not imply intent unless context suggests it; for example, a parked bicycle may 'dǎng lù' without intention. While it can be used metaphorically (e.g., 'this policy is blocking progress'), its core usage remains grounded in spatial obstruction and is most frequent in urban, transportation, or household contexts.
