Friday afternoon, second period, Physics class.
At this usual time, Teacher Ouyang would have abandoned the students and headed to his part-time tutoring class in An City. Unfortunately, now he's been sanctioned by the school.
Teacher Ouyang is in his forties, afraid to quit his job. One reason is the lack of pension, the other is losing his permanent position; if he goes tutoring again, his credentials wouldn't look as impressive.
So he had to stay at school to teach physics, then attack the tutoring classes during winter and summer breaks.
He was hoping for peaceful days, but ended up being targeted by the P.E. teacher!
So before class started, Teacher Ouyang specifically explained that this class was about comprehensive dynamics problems, and once missed, he wouldn't teach it again.
To curb the influence of the P.E. teacher.
