Nowadays，with the popularity of Internet，people like to talk or make comments on the hot news，then they create many popular languages and they spread so fast that a lot of people will talk in people advise to cancel the use of the slang，but I don't think it is a good le know they shouldn't use these slangs on official papers，they use them only in the private 's more，slangs provides a funny way for people to express themselves and it is a good way to show humor.I am a great supporter of these slangs，because I can talk happily with my friends.
