自我介绍。

I can give you some suggestions.First of all,you could start from saying“你好”.But in most situations,we don't say “很高兴认识你”（it is just used in some formal situations).In our daily life,we simply say“你今天过得不错吧？” .If you're talking with a new friend,you should introduce yourself more like (Where are you from?What do you do for a living? etc.). If you still have some questions,you can ask me.I'd like to help you!
