Mo Jing Hao is a short Mandarin-language meme audio that circulates online under the characters 魔鏡號, literally meaning 'magic mirror'. It became popular as a reaction and reveal sound in Chinese-language meme edits and short-video culture, where creators use its theatrical spoken delivery as a cue for dramatic unveilings, beauty transformations and joke product reveals. The exact original broadcast or recording it was taken from is not documented in public sources, and it spread the way many meme clips do: copied from edit to edit because the delivery is instantly recognisable. Today it functions as a compact reveal sting that signals to viewers a big, usually funny, moment is about to land.
