The Chinese title xi qi simply means inhaling or taking a breath in, which describes the clip exactly rather than naming a film or character. Short breath and gasp clips like this spread on soundboards and in video edits because they are language free and instantly readable across cultures. Editors reuse the sound for anime, gaming and reaction memes where a character needs to show shock without saying anything, and its tiny length makes it easy to layer over dialogue, captions or a sudden zoom without masking other audio.
