On Tuesday afternoon, Zhaxi was sitting in the demonstration room revising the fifth draft of his thesis when his phone rang. It was Professor Yang.
"Come to my office!"
Zhaxi put down his computer and jogged over, knocked on Professor Yang's office door, Yang Ping raised his head and pointed at the chair opposite: "Sit!"
A pile of literature was spread out on the desk, all about Clostridium difficile infections. Zhaxi recognized a few of them, the ones he had consulted when writing his thesis. Yang Ping had a printed copy of Zhaxi's paper in his hand, still with red pen annotations.
"I've read your thesis, fifth draft!" Yang Ping placed it on the desk, flipping to the first page, "It's much better than the fourth draft, but there are still issues."
Zhaxi's heart tightened: "What issues?"
Yang Ping didn't answer directly, but asked him instead: "Let me ask you a question, how long did you spend writing this thesis?"
Zhaxi thought for a moment: "On and off for about a week."
