Qi lai yi xia is a common everyday phrase in Mandarin, so this clip spread as a reusable reaction sound rather than a line tied to one known show or creator. Its meaning is immediately clear to Mandarin speakers and easy to guess from context for others, which helps it work in short videos, edits and soundboards. The very short length makes it easy to loop, layer over a wake up scene, or drop into a chat as a voice style joke about getting up, moving seats, or starting work.
