      In the busy city of New York, such an astonishing thing ever happened.
     On a Friday night, a poor young artist' stood at the gate of the subway station, playing his violin. Many
 people slowed down their paces, and put some money into the hat of the young man.
     The next day, the young artist came to the gate of the subway station, and put his hat on the ground
 gracefully. Different from the day before, he took out a large piece of paper and laid it on me ground and
  put some stones on it. Before long, the young violinist ,was surrounded with people, who were all
 attracted by the words on that paper. It said, "Last night, a gentleman named George Sang put an i
 mportant thing into my hat by mistake. Please come to claim it soon."
     Seeing this, it caused a great excitement and people wondered what it could be. After about half an
 hour, a middle-aged man ran there in a hurry and rushed through the crowd to the violinist and grabbed his
  shoulders and said, "Yes, it's you. You did come here. I knew that you're an honest man and would
 certainly come here"
     The young violinist asked calmly, "Are you Mr. George Sang?"
     The man nodded. The violinist asked, "Did you lose something?"
     "Lottery, it's lottery," said the man.
     The violinist took out a lottery ticket on which George Sang's name was seen. "Is it?" he asked.
     George nodded promptly and seized the lottery ticket and kissed it, and then he danced with the
 violinist.
     The story turned out to be this: George Sang is an office clerk. He bought a lottery ticket issued by a
 bank a few days ago. The awards opened yesterday and he won a prize of $500,000. So he felt very
 happy after work and felt the music was so wonderful, that he took out 50 dollars and put in the hat. How
 ever the lottery ticket was also thrown in. The violinist was a student at an Arts College and had planned
 to attend advanced studies in Vienna. He had booked the ticket and! would fly that morning. However
 when he was cleaning up he found the lottery ticket. Thinking that the owner would return to look for it, he
  cancelled-the flight and came pack to where he was given the lottery ticket.
     Later someone asked the violinist: "At that time you were in needed to pay the tuition fee and you had
 to play the violin in the subway station every day to make the money. Then why didn't you take the lottery
  ticket for yourself?"
     The violinist said, "Although I don't have much money, I live happily; but if I lose honesty I won't be
 happy forever."
