dep the means so beautiful :)

Đẹp thế! - How nice/beautiful it is! Chiếc ô tô này đẹp thế! - How nice this car is!/What a nice car! Bức tranh đẹp thế! - What a nice painting!

This dialogue is quite funny ^^

đẹp thế! it means: that a nice!

Sorry, I thought this was a question about English. Ignore my comment. :(
