The word **收工** is a verb-object compound, formed by combining the verb **收** (shōu, meaning "to collect," "to put away," or "to bring to an end") with the object **工** (gōng, meaning "work" or "labor"). Literally, it paints the image of "gathering in the work" or "putting away the tools," which metaphorically extends to signify the act of stopping work for the day, concluding a task, or knocking off from a job. It is most commonly used in informal or colloquial contexts, such as on a construction site, in a workshop, or at the end of a day's labor, to announce that work is finished.
