"Doesn't understand physics?"
"What's that supposed to mean?"
Director Zhang of the Science Academy's Physics Department was taken aback hearing Qian Zhijin say so over the phone, "Zhao Yi said he doesn't understand physics?"
"That's what he said."
Qian Zhijin was a bit miffed with Zhao Yi's attitude, but considering their camaraderie which was far superior to that of Director Zhang's, he thought it wasn't appropriate to directly voice the concern. Coming up with a rational explanation, he added, "At the time, he was engrossed in his research. You may not be aware that he gets quite irritable when he is researching and not to be disturbed."
"Moreover, young people are tough to figure out. I don't understand what he meant either, he may have just given a casual response without grasping the meaning."
"Once he finishes his research, I'll ask again."
Processing Qian Zhijin's words, Director Zhang obligingly said, "That'd be appreciated, Professor Qian."
