Zhang Tiejun, 14, Sichuan: On my first day of middle school, the teacher asked us to sit according to height. The shorter students would sit in the first rows (排), and the taller in the last. I am one of the shortest, but he asked me to sit in the last row. With tall classmates in front of me, I had to stand up to see the blackboard and take notes. I got high scores in the next midterm exam, and the teacher put me in the first row.
