The clip circulates under a Chinese-language upload title that credits Da Shi and labels the audio as a yes-or-no moment, but no wider source work, show, or original recording is identified in the information supplied with it. In that form it has found a small online audience as a ready-made reaction sound rather than as a quotation from a familiar programme. Its appeal is practical: the choice is instantly understood, the clip is short enough to drop into almost any edit, and the binary format suits polls, quizzes, challenges, and playful interrogations that need a fast answer.
