Classical Chinese poetry used
嘤嘤 for birdsong (《
诗经·
小雅·
伐木》: '
伐木丁丁,
鸟鸣嘤嘤' — 'chop chop go axes, chirp chirp go birds'). Modern Chinese internet culture revived
嘤嘤嘤 as a cutesy fake-crying noise, especially among young women and in anime fan communities — equivalent to English 'sniffle sniffle' or 'wahh'.
