Pius的說明：I performed this at the Wah Yan International Conference gala dinner in Aug 2010 in L.A. here. A lot of people liked this. As a matter of fact, I did this performance 4 times in the past 2 years for different associations at their events. You can find some of them on youtube. If I had a chance, I like to show it to Mr. Wong Chin Wah & seek for his comments.
