The pace of Saturday's classes was the same as Friday's.
The chemistry teacher, Old Zhang, held a piece of chalk in his left hand and a crumpled review handout in his right.
His forehead glistened oilily under the fluorescent lights, and his sparse, graying hair trembled slightly in the breeze from the fan.
Whenever he turned to write on the blackboard, the smooth patch of skin on the back of his head would take on a cold, metallic sheen in the blue light of the projector.
The scraping of chalk against the blackboard abruptly ceased. Old Zhang spun around, his eyes widening behind his glasses. The piece of chalk between his fingers snapped on the lectern with a CRACK.
A moment later, a piece of chalk accurately struck Chen Mingyu, who was fast asleep on his desk.
"Chen Mingyu!"
Old Zhang's booming voice instantly jolted Chen Mingyu from his slumber.
The extremely sleepy Chen Mingyu raised his head, and Old Zhang was startled by his haggard face.
