The primary purpose of this sparring is to show the spectator the agility and skill of the demonstrator and the physical application of every single movement . This is normally accomplished with repetition of the same movement in slow motion.
The role of the counterpart in the demonstration is to provide a precise target upon which the demonstrator acts. The distance between the players can be adjusted freely by the demonstrator, and the counterpart executes only one blow that can be rearranged during each display.
