You don't say.
After the groups of students calmed down, they were quite self-aware. One of the boys said to Principal Ding, "Principal Ding, we accept the punishment, but can we finish watching the match before we go?"
"Sure."
Principal Ding wasn't such an uncompassionate person.
Anyone at the Fifth Canteen at this time was either a food lover or a true fan of the League of Legends matches.
Clearly, these groups were avid League of Legends fans. Just now, they had verbally clashed over the match between Dragon City LC team and Korea's Big Tiger team, which almost escalated into a physical fight.
It was just that no blows were exchanged, so the consequences weren't so severe.
Thus, Principal Ding had given them a school-wide notice for criticism as their punishment. If they had actually fought, the impact would have been significant, at least warranting a probationary punishment.
