Realistic Training VS Choreographed Movements
From The Fox Bagua Zhang Blog
First let me remind you that the generations before us were not idiots. They lived in a time of continual war against countless odds, which lead to the development of martial arts. Because they were in a warring period, there are many obvious factors that they didn't need to explain, that people today may not be aware of. All of the movements that were passed along basically represent a simple alphabet that we can learn in order to become more literate in a scenario of violence. So all of the movements from every style have proven to be effective or they would not exist today. Whether you are worried about knife counters, spear counters or gun disarms, these movements have all been successful at one point.
