中国数字 Eight八

The word for "eight" (八bā) sounds similar to the word which means "prosper" or"wealth" (發fā)– often paired with "發財" during Chinese New Years, but is used alone or paired with numerous other "compound words" that have a meaning of luck or success. In regional dialects the words for "eight" and "fortune" are also similar. Note as well, this particular symbol matches the mathematical symbol of infinity. While Chinese does have other words for luck, this full understanding of luck that includes the infinity concept marries into a Chinese understanding of this particular word.

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").

The number 8 is viewed as such an auspicious number that even being assigned a number with several eights is considered very lucky.

It is already common in Hong Kong for ~4th floors not to exist; there is no requirement by the Buildings Department for numbering other than that it being "made in a logical order." A total of 43 intermediate floor numbers are omitted from 39 Conduit Road: those missing include 14, 24, 34, 54, 64, all floors between 40 and 49; the floor number which follows 68 is 88.
