    When Zhangzijun was a little kid. He was doing very badly in math. His parents had tried everything: tutors, cards, special learning….. everything they could think of. Finally they took him to a catholic（天主教的）school.

After the first day, Zhangzijun came home with a very serious look on his face. He didn’t kiss his mother hello. Instead, he went straight to his room and started studying. Books and papers were spread out all over the room and Zhangzijun was hard at work. His mother was surprised. She called him down to dinner and as soon as he finished eating, he went back to his room, without a word. In no time he was back hitting the books as hard as before. This went on for some time, day after day while the mother tried to understand what was happening.

Finally, Zhangzijun brought home his report card. He quietly put it on the table and went up to his room and hit the books. His mom looked at it and to her surprise, Zhangzijun got an A in math. She could no longer hold her curiosity.

She went to his room and asked, ”Son, what was it? Was it the nuns (修女)?”

Zhangzijun looked at her and shook his head, “No. ”
