Wing Chun Kung Fu was created by five kung fu grandmasters (known as the 5 elders) in response for a need of Shaolin to train soldiers quicker than the 15 to 20 years it took to master the typical animal systems. This new system was based on efficiency, and the scientific principles of structure, space, timing, and energy.
Wing Chun is mainly known for its straight line techniques and centerline theory. However, Wing Chun has effective grappling in the form of Chin Na. While a Wing Chun person would prefer to stay away from ground fighting, the base concepts of the centerline and triangulation theories make for effective ground fighting as well. Like any martial art born of warfare, Wing Chun is a complete art. It is not just striking
Like many systems today, there are a split among the Wing Chun world. Wing Chun is primarily split into two camps of fighting theory, centerline and central line. Centerline tend to have higher stances and fight from the center out. The central line theory tries to take the flank and attack the centerline from a superior position. Yip Man is an example of centerline, William Chun an example of central line.
