Take a look at this clip. It is a clip of my student, PL, doing the Yum Chui :-
For the fun of it I asked the Slack SKD Learning Group how long they thought PL has learned the Yum Chui. Two members guessed a week.
I have said that SKD is not difficult to learn and this video helped to make my point. The reason – PL had only learned it about 10 minutes before this video was taken.
