Cantonese internet slang

Characteristics
 Code-switching
The Cantonese-English code-switching is the insertion of isolated English words into a Cantonese Chinese syntactic frame. It can save time by adding a shorter English word or expression into a Cantonese Chinese sentence without distorting the original meaning.
 Abbreviations
Abbreviation is the shortened form of a word used for saving time, enhancing playfulness and acting more like speech. People can share the same codes of language and thus it fosters a sense of peer-group feeling.

 Rebus Writing
Symbols or words are used to represent another word that is similar in sound, regardless of the original meaning of the symbols. In Cantonese Internet Slang, "88" is often used to represent "bye bye". The sound of "8" is borrowed to represent the word "bye".
