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 slangs.Some people advise to cancel the use of the slang,but I don't think it is a good choice.People know they shouldn't use these slangs on official papers,they use them only in the private occasions.What'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.
