章 620: Genuflecting!

Those teachers who were present stared doubtfully and anxiously at Zhang Ye who was speaking with fervor and assurance. This was no longer just a simple lesson on elementary math problems anymore.

"Who is this person?"

"What's his background?"

"Is he really a math teacher?"

"I've never before come across these types of questions that Chenchen's guardian set, nor even heard of such questions coming from other schools or appearing in any textbooks, so could he have come up with them spontaneously?"

"This problem is really quite wonderful!"

"That's right, there's a hidden catch!"

"It looks difficult, but is in fact really simple."

"Yes, it looks easy, but is in fact difficult too."

"Why do I feel that he looks really familiar the more I look at him? I can't see his face clearly when he's wearing those sunglasses!"

The teachers were discussing the experience Zhang Ye had led them through just now, leaving them with mixed feelings and a sense of reflection.
