어제 시험본것도 아니고 사람마다 무슨 문제냐가 달라서 정확히는 모르겠지만 뭐 디투어를 사용하자면 일단 말부터 싸지르고 봐야죠

뭐 전화문제인가요?

그렇다면 you gave me a call saying there's a heavy congestion in front of the university because it is under construction.

and you went on to say that the detour is hard to find.

To solve the problem, I think you can go either way.

First of all, if I were you, I'd probably put up a sign that says where the detour is.

Then, people for coming to visit our university will not be confused about find the direction. And, it doesn't take much time for us. Since this is kind of urgent, we need to do something that is simple and done quickly.

Also, we can let people know by making a post about the detour on our website.

Because, most people have smartphone these days and so, they can go online on the way to our university, posting on our website can be easily noticed. People won't miss it.
