"Hello, I'm trying to find out if you know a teacher named Wang Dafu at this school?"
"Wang Dafu? We have a teacher with that name? I have no idea. Do you know which department he belongs to?"
"I don't know. I just know his name is Wang Dafu, and he published an article called 'On Cow Dung' in the Agriculture and Technology magazine two months ago."
"Oh dear! That'll be hard to find! I'm also new here and not familiar with this. You'd better ask someone else."
"Alright, thanks anyway…"
"..."
"Hey there, I'm trying to find someone. Do you know of a teacher named Wang Dafu at this school? He published an article in the Agriculture and Technology magazine two months ago."
"Huh? Are you sure he's in our school? I've been here for three years, and I've never heard of a teacher named Wang Dafu."
"He must be! The name Provincial Agricultural University was written at the end of the article!"
"Can I see the article?"
