"The teacher says, "Please come in!""
These quotes seem to not work very well, I can't get it to work with any combination of quotes or space or commas. Even when I copy and paste the correct answer it doesn't work.
Apart from the fact this course universally uses Simplified Chinese, I would agree.
Traditional Chinese is accepted everywhere on Duolingo. Therefore, it seems a bit odd that here it doesn't work.
It works if you just leave out all the punctuation completely. 老师说请进 was accepted, but the quotes really, really need to be fixed.
This example seems to be over-fussy about punctuation.
Actually on checking the punctuation is broken. The only way I could get past this exercise was cutting and pasting the answer from this discussion! THIS REALLY NEEDS FIXING!!!!!

进来 = come in, but you need the "please", which is 请. So 请进 = please come in. I think DL should accept 请进来 (but they dont)
I put 老师说，“请进！” instead of 老师说“请进”, which is the "correct answer". Duolingo didn't accept it. This is absurd.
