Everyone sat stiffly in their seats, terribly nervous. They knew that a rare master was about to appear, a man said to possess learning that reached the heavens.
The teacher wrote a single character on the blackboard.
Teacher: "Do you recognize this character?"
Everyone: "Ren!"
Teacher: "Do you know what it means?"
Everyone: "Ren means benevolence and virtue!"
Teacher: "Wrong! 'Ren' means a person and the number two. It's a technique for splitting a person in two!"
With that, the teacher struck out with one palm, splitting the entire private school in two.
