Wing Chun; thanks primarily to the late Bruce Lee, wing-chun is one of the most popular external Chinese styles. Lee's first formal training came in wing-chun, and when he became well known as a martial artist and actor, wing chun became popular as well. Wing Chung stands apart from other martial arts for two reasons: It’s the only style that was created by a woman, and compared to other traditional Chinese combat systems, it can be learned relatively quickly. Wing-chun is a very explosive art whose practitioners employ low kicks and fast hand techniques, and utilize the concept of simultaneous attack and defense. Wing-chun is often referred to as "the thinking man's art" because it follows a scientific approach to training. Its use of so-called "feminine qualities" such as softness, passivity and sensitivity must be experienced firsthand to be fully understood. Wing-chun training helps practitioners develop self-awareness, agility and flexibility. It teaches them to use proper timing and correct positioning to defeat an opponent. Wing Chun is unique because of the mental and intellectual part of its training. It has perfectly logical movements which are natural and promote spontaneity.
