Four
Main article: Tetraphobia
Number 4 (?; accounting ?; pinyin s?) is considered an unlucky number in Chinese, Korean, Vietnamese and Japanese cultures because it is a homonym with the word "death" (? pinyin s?). Due to that, many numbered product lines skip the "4": e.g. Nokia cell phones (there is no series beginning with a 4), Palm[citation needed] PDAs, Canon PowerShot G[citation needed]'s series (after G3 goes G5), etc. In East Asia, some buildings do not have a 4th floor. (Compare with the American practice of some buildings not having a 13th floor because 13 is considered unlucky.) In Hong Kong, some high-rise residential buildings miss ALL floor numbers with "4", e.g. 4, 14, 24, 34 and all 40-49 floors. As a result, a building whose highest floor is number 50 may actually have only 36 physical floors.
In Singapore during the early 2000s, Alfa Romeo introduced a new model, the 144. Nobody bought it, so they had to change the model number.
Number 14 is considered to be one of the unluckiest numbers in Chinese culture. Although 14 is usually said as ?? "sh? s?," which sounds like ?? "ten die", it can also be said as ?? "y? s?" or ?? "y?o s?", literally "one four". Thus, 14 can also be said as "y?o s?," literally "one four," but it also sounds like "want to die" (?? pinyin y?o s?). In Cantonese, 14 sounds like "sap6 sei3", which sounds like "sat6 sei2" meaning "certainly die" (??).
Ironically, in the Rich Text Format specification, language code 4 is for the Chinese language.

Very interesting.
