You can use it instead of many words such as “new" or "surprising"．Here's an interesting story we can use to show the way the word is used．A teacher asked her students to write about the waterfall（瀑布）they had visited．On one student's paper was just the one sentence, “It's so cool．Maybe he thought it was the best way to show what he saw and felt.
