She had noticed that Ding Yu had removed a few screws from her chair. However, after a brief analysis of the force acting on the chair, she had sat in the front half of the chair, which had avoided the spot where the chair had fallen apart.
Ding Yu was like a hothead. He just sat down and naturally the chair would fall apart.

Cheng Ling looked at Wu Ya, who was watching the fun in the first row, and then looked at Ding Yu.
"How about you two play a guessing game? I'll wait for whoever wins. After all, I can't be in two places at the same time."
The math teacher was a short man. He was very skinny and looked like he was afraid of Ding Yu. He waved his hand and said, "Cheng Ling, go to the empty classroom on the fourth floor and bring another chair down. Don't delay our class."
