KT Chao illustrates some good YM drills. He was a private student
of YM who put him through those drills.
Among other things- he has the double punch- which Fong did a lot of in
his own training days with Ho kam Ming and thought that it was
important enough to note it or put it into the basic text - slt -in the section with
other two handed motions including fan, ding and jam.
