Having Shaolin roots is only the first step. Completeness brings the art into reality. Wing Chun is reproducible in its training because it is based in science. It has theories, formulas, gates, and lines which define its very existence. With a scientific system you can teach it from generation to generation and still maintain the system in tact. The consistency of the deployment of the system is because it is scientific in nature and the only inconsistency is when nature is violated. As with any system the expectations are for a predictable outcome. When a Wing Chun practitioner engages an opponent he uses his martial science of the gates, 3 dimensional references, and efficiency to deploy and simultaneously defend his space and expects, and in most instances enjoys a predictable outcome.
A complete scientific martial arts system must be effective in all ranges of hand-to-hand combat. There are four ranges in hand-to-hand combat; long kicking, long striking, trapping, and grappling. The Wing Chun practitioner can engage his opponent at all four of the hand-to-hand combat ranges. At the long kicking range, where he would encounter opposition from those trained in expert kicking techniques, he eliminates the opportunity for his adversary to gain an advantage by controlling the space using footwork and locking onto his opponents centerline, closing the distance and avoiding his opponents attacks and “Becomes” the space and moves to the long striking range. At the long striking range, where he encounters an adversary who can box and strike, he uses his knowledge of time and space to intercept and redirect his opponents attack to gain superior position and again controls the space, and advances to the trapping range. In the trapping range he calls upon his Wing Chun skills to deploy his weapons and destroys his opponent. If his opponent causes him to go into the grappling range he first uses the methods to subdue his opponent without committing to “earth” fighting, if not successful he uses the applicable techniques to escape and subdue his opponent. In the Wing Chun training it is paramount to learn how to “deal” with an adversary in all ranges of combat. Within the four ranges of combat the techniques of Ti, Da, Suai, and Na are applicable. In any of the ranges you must be able to control the space and destroy your opponent.
