　　George Sang is an office clerk．He bought a lottery（彩票） 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．When he get to the gate of the subway station，he saw a poor young artist standing there and playing his violin．He felt the music was so wonderful that he took out 50dollars and put the money into the hat in front of the young man．However 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 back to where he was given the lottery ticket and gave the lottery ticket to George Sang．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．"
