However, the current visitor is evidently the first case.
Nan Zhubin thought for a moment and decided not to guide the conversation immediately.
The visitor continued on his own: "But this morning, after finishing my chat with Chen Lizhou, I just..."
He suddenly looked up: "Teacher Nan, you know Chen Lizhou, right? I saw you greet him in the elevator before. He's the director of our department, I'm under him."
Nan Zhubin didn't directly answer the question because he wasn't sure how much Chen Lizhou had disclosed about their consultation to the visitor.
Without his own permission, all his relationships with Chen Lizhou are protected by confidentiality agreements.
But Nan Zhubin couldn't deny knowing Chen Lizhou either, as that would violate the principle of [sincerity] toward the visitor.
So Nan Zhubin took a detour, posing a guiding question back: "It sounds like something happened between you?"
