The Hui Zhan name comes from the Chinese term for an exhibition or trade show, and the clip is shared online as a short, easily reusable sound rather than as part of a widely identified song, film or television moment. With no clear single source attached to it in the available information, its appeal comes from that simple association: it instantly suggests a convention floor, a display booth or a public event. Creators reuse it for themed edits and reaction clips because the short length fits modern short-form video pacing.
