After Jiang Cheng left Teacher Lü's office with a grin, she first took a turn in another office.
She came in and out, holding a small stack of papers, reading as she walked, nodding as she read, occasionally shaking her head.
A group of teachers, full of curiosity, leaned against the window, and the door, peeking out one eye into the hallway, watching Jiang Cheng nod and shake her head.
"She shook her head? Did she see mine? I wasn't too confident in solving the problem yesterday."
"Maybe it's mine."
"What kind of day is this, to be completely at the mercy of a student."
The teachers retreated.
"No way, I have to test Jiang Cheng, I just refuse to believe it."
A teacher, full of resolve, left with a book to teach Jiang Cheng's class.
After one class, the teacher returned with five sheets of paper.
"In fact, having smart students is an honor for us teachers."
The teachers: Plaid—figure it out yourselves.
