In Chinese culture
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. 88 is often used to mean "bye bye" in Chinese-language chats, text messages, SMSs and IMs. 88 is pronounced in Chinese Mandarin language as "ba ba" ("bā bā" to be precise), simulating the sound of the English language "bye bye".
In Amateur Radio
88 is used as shorthand for 'Love and kisses' when signing a message in Amateur (ham) Radio. It is used in spoken word (radiotelephony) morse code (radiotelegraphy) and in various digital modes. It is considered rather more intimate than '73', which (roughly) means 'best regards', and therefore 73 is more often used. The two may be used together. Sometimes the 88 or 73 is pluralized by appending an s. These number codes originate with the 92 Code adopted by Western Union in 1859.
In white nationalism
Modern Nazis use the number 88 as an abbreviation for the salute Heil Hitler. The letter H is eighth in the English alphabet, whereby 88 becomes HH. 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 nationalist. Example uses of 88 include the song "88 Rock 'n' Roll Band" by Landser, and the organizations Barselc88, Column 88, Unit 88, and White Legion 88. Gunman and author James von Brunn signed his works as "JVB-88." Currently, the Michigan-based ANP uses 14 in its domain name and 88 as part of a radio sign-off.
