Prague concert

Dear Mr. Ma,

Thank You very much for Your concert yesterday in Prague at Spanish Hall.
You played in Prague after 20 Years. I was on this concert 20 Years before like a young student. Now I am a professional cellist (but not like You Smiling). I play in The National Theatre Orchestra in Prague.
I am Your big fan. I had a great dream to see you live again.
Thank You for Your autograph. I know You was very busy after yesterday's concert . Even so You did short time to do quick autograph.
Thank You very much. (sorry about my bad english)

Best regards
