In Chinese cultureEdit
Number 88 symbolizes fortune and good luck in Chinese culture, since the word 8 sounds similar to the word fā (发, which implies 发财, or wealth, in Mandarin or Cantonese). The number 8 is considered to be the luckiest number in Chinese culture, and prices in Chinese supermarkets often contain many 8s. The shape of the Chinese character for 8 (八) implies that a person will have a great, wide future as the character starts narrow and gets wider toward the bottom. The Chinese government has been auctioning auto license plates containing many 8s for tens of thousands of dollars. The 2008 Beijing Olympics opened on 8/8/08 at 8 p.m.
In addition, 88 is also used to mean "bye bye (拜拜)" in Chinese-language chats, text messages, SMSs and IMs. 88 can be seen as shorthand for 8181, which when pronounced in standard Mandarin is almost identical to "bye bye".
In amateur radioEdit
In amateur radio, 88 is used as shorthand for "love and kisses" when signing a message or ending an exchange. It is used in spoken word (radiotelephony), Morse code (radiotelegraphy), and in various digital modes. It is considered rather more intimate than "73", which means "best regards"; therefore 73 is more often used. The two may be used together. Sometimes either expression is pluralized by appending an -s. These number codes originate with the 92 Code adopted by Western Union in 1859.
In white nationalism and supremacismEdit
Often, this number is associated with the number 14, e.g. 14/88, 14-88, or 1488; this number symbolizes the Fourteen Words coined by David Lane, a prominent white supremacist. Example uses of 88 include the song "88 Rock 'n' Roll Band" by Landser, and the organizations Column 88 and Unit 88. Currently, the Michigan-based American Nazi Party uses 14 in its domain name and 88 as part of a radio sign-off.
