Language in my country and in my opinion

I think people have slang in every language.We have "giliverble" in China means powerful or wonderful ,just like "guys" in English.It's normal but in different amount from different languages.There is much slang in China every year and we even choose the most representative one to ten to write into the dictionary.Using slang shows you easygoing and fashion sometimes in a proper extent,of course some bad ones make you sound stupid.I don't think using slang will lead standards of language to fall,and it's just a way of language boarding.But I still think it is important to have a good grammar,I do it well in Chinese and speak well.In fact,I want to study some polite slang in English,which can make me know more about the culture,also the development of English spoken. Besides,I agree with the idea of Emma,the famous young actress in Britain,about slang.I'll still study grammar and right express of English,maybe pick up some slang.After all,most of the slang belongs to "teenspeak" but differently from our parents and grandparents.I want to communicate well with the people of the same generation,but also my parents and grandparents.
