To this I will add there is no better or worse martial art. They are all good. They all provide a way of self enhancement. Another determining factor for better or worse is the viewer's interpretational skills. As to the differences between the Arnis and Kung Fu.
Most people are quite surprised to see the relevance between the two martial disciplines.
Most of both of these martial arts are designed around the concepts of flow. With that in mind one must not forget the human anatomy can only move in so many directions. So in reflection to this we see how movements can easily be carbon echoed between both martial arts disciplines, even though the translations reflect the creativity of the practitioners. So its quite often that the trained eye can see the relevance between the two worlds of martial science. Most of the differences we are to notice are culturally influenced pertaining to code of ethics, conduct, warfare strategies, philosophy, religion, etc.
