"The word for "eight" (八 Pinyin: bā) sounds similar to the word which means "prosper" or "wealth" (发 - short for "发财", Pinyin: fā). In regional dialects the words for "eight" and "fortune" are also similar, e.g. Cantonese "baat3" and "faat3".

There is also a visual resemblance between two digits, "88", and 囍, the "shuāng xĭ" ('double joy'), a popular decorative design composed of two stylized characters 喜 ("xĭ" meaning 'joy' or 'happiness').
