I think, it's better to say the smell of mandarins, not fragrance. Anyway, I don't know)
So, the smell of mandarins. It's one of the symbols of the New Year! Winter holidays are coming, we have to prepare for it. People care about presents, dishes, guests. Students are waiting for coming to their native towns (my classmates and me too). Let's don't give up, when we will be at home, we make all "new year things". But now there are lessons, session. And then the fragrance of home!
