Hidden applications is a silly concept ...
Form training can be used for:
1. combat,
2. performance, and
3. health.
When people try to apply performance (2) into combat (1), no matter how smart you are, you will never be able to figure out the true application from performance because there is none.
In the following clip, the way that he moves his right arm makes no sense at all.
In the long fist system, there are a lot of forms that are finished like this. When I was a student, my long fist teacher told me this move could be used for
- reach to my right pocket,
- pull out a throwing knife, and
- throw at my opponent.
Even today, I still cannot throw a knife with any accuracy by this method.
It's just a nice "performance" move. When I do the move, I have changed it into an upward block.
