A 10-year-old boy decided to study judo(柔道) despite the fact that he had lost his left arm in a terrible car accident. The boy began lessons with an old Japanese judo master， and he was doing well. But he couldn't understand why， after three months of training，the master had taught him only one move.
"Sir，" the boy finally said， "shouldn't I be learning more moves?"
“This the only move you know， but this is the only move you'll ever need to
know，" the master replied.
Not quite understanding， but believing in his teacher， the boy kept training.
Several months later， the master took the boy to his first tournament(錦標賽).
Surprising himself， the boy easily won his first two matches. The third match
proved to be more difficult， but after some time， his opponent became impatient and charged; the boy skillfully used his one move to win the match. Still amazed by his success， the boy was now in the finals.
This time， his opponent was bigger， stronger， and more experienced. For a while，the boy appeared to be overmatched. Concerned that the boy might get hurt , the referee alled a time-out ,He was about to stop the match when the judomaster intervened.
"No，" the judo master insisted，"Let him continue."
Soon after the match resumed， his opponent made a critical mistake: he dropped his guard. Instantly， the boy used his move to pin him. The boy had won the match and the tournament. He was the champion.
