Numbers in Chinese culture

8
The word for "eight" (八 Pinyin: bā) sounds similar to the word which means "prosper" or "wealth" (發 – short for "發財", 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").
 * Singapore Airlines reserves flight numbers beginning with the number 8 to routes in China and Korea.

4
Number 4 (四; accounting 肆; pinyin sì) is considered an unlucky number in Chinese because it is nearly homophonous to the word "death" (死 pinyin sǐ). For the Chinese New Year routes, it had omitted the '4' and as well, train numbers cannot start with '4' on Singapore MRT. iPhones had omitted the '4' on certain plates.
