Principles are more important than blind learning.
When we understand how to move we can apply the principles to improve the way we move.
For example, when I learned how to do Biu Jee I wasn’t taught how to flow. It was only until I met my final Wing Chun teacher from an older style that I learned how to move better.
Applying an improved understanding can enable me to do the movements of the Biu Jee form in a more alive, dynamic, soft manner while delivering power.
