He seemed to have discovered that the teaching director standing at the door pushed his eyes and asked in surprise: "Teacher Zhou, why are you here?"

Wu Rui smiled slightly: "I'm giving them tutoring. Raising the average scores of our grades and improving the admission rate of our school is the urgent responsibility of every student."

Director of the Teaching: “…………”
