Meanwhile, the Chinese use 555 to express the opposite emotion: crying! Because 555 (wu wu wu) sounds very similar to 呜呜呜 (also wu wu wu), an onomatopoeia for the crying sound. 555 is a bit of a dated expression nowadays though, it saw greater use during the SMS era. It's especially interesting since "five" in both languages are cognates with each other, having descended from Old Chinese /ŋaːʔ/.
