"What's going on?"
"Why is it like this? I find my own lecture boring, so how is it that Zhao Yi appears so engrossed?"
Finally.
The class ended.
Wang Gang took a deep breath, smiled, and turned to Zhao Yi, "Academician Zhao? How was it? Was there anything you didn't understand?"
"You were very clear, I understand everything." Zhao Yi said with a satisfied smile, "You're indeed a wonderful teacher, I plan to attend your next class as well."
His words seemed sincere and full of admiration.
Wang Gang was rooted to the spot, reflecting back on the lecture, he couldn't see anything 'exceptional' about it.
...
After class.
As Wang Gang was leaving the classroom holding his textbooks, he saw a familiar figure quickly descending the stairs. Without thinking, he called out, "Old Hu? Hu Zhibin?"
"Huh?"
"Clomp, clomp."
