Jiafei became a TikTok meme after clips of the Chinese product seller's intense, sing-song livestream style were reposted, remixed and turned into parody characters online. Users began isolating the vocal delivery as a standalone sound, using it over unrelated products, pets and awkward reveals. Its popularity comes from the contrast between a serious sales pitch and completely unserious footage, plus how recognisable the cadence is even to viewers who do not speak Chinese. The clip remains a shorthand for fake advertising energy.
