Cultural significance

In Chinese culture

Number 88 symbolizes fortune and good luck in Chinese culture, since the word 8 sounds similar to the word (, which implies 發財, 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 () 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 at 8 p.m., 8 August 2008.[8]

In addition, 88 is also used to mean "bye bye (拜拜)" in Chinese-language chats, text messages, SMSs and IMs, because its pronunciation in Mandarin is similar to "bye bye".[9]

In amateur radio

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.[10] These number codes originate with the 92 Code adopted by Western Union in 1859.

In neo-Nazism

Nazi graffiti with the number 88

Neo-Nazis use the number 88 as an abbreviation for the Nazi salute Heil Hitler.[11] The letter H is eighth in the alphabet, whereby 88 becomes HH.[12]

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.[13] Example uses of 88 include the song "88 Rock 'n' Roll Band" by Landser, and the organizations Column 88 and Unit 88.

The number is banned on Austrian license plates due to its association with "Heil Hitler [and] where H comes in the alphabet".[14] In June 2023, the Italian Football Federation (FIGC) and the Italian government announced that the number 88 would be banned from use in Italian association football, as part of a joint initiative to combat antisemitism. This followed an incident in March of that year in which a Lazio supporter wore a club shirt bearing the name "Hitlerson" and the number 88, which led to the supporter receiving a lifetime ban from attending Lazio matches.[15]
