I love Kung Fu Movies, so a title like Five Incredibly Deadly Kung Fu Styles is most excellent. When you speak of these arts, however, you aren't just discussing cinema. You are delving into incredibly potent regimens that are the most dangerous martial arts on the planet.
These are specific body disciplines which steel the body and make sharp the mind. People who engage in these arts have gone beyond the flesh, and are describing a world towards which mankind hurries with appreciation. Let's consider the five deadly Kung Fu styles.
No particular order to our consideration, let's begin with Shaolin Gung Fu. Inspired by the immortal Bodhidharma, it has become the most powerful influence in the martial arts world. In Shaolin you are talking about the absolute protection of creating an iron body through Golden Bell Training, and the steel fingers that eventually result in Dim Mak (the death touch).
Many arts claim lineage to Shaolin, and Wing Chun Gung Fu is first in line. Sometimes thought of as a 'girly art' because it was founded by a nun, this art shows that being sensitive to an attacker enables one to lay waste to an attacker. Learn the Sticky Hands (Chi Sau) drill and you know what is coming before your opponent even thinks of it.
Another sensitive art is the Praying Mantis (Tang Lang Ch'uan). Again, the arms intertwine in a training drill, but the attack and defense is delivered from a stronger Shaolin type of stance. Shaolin Powerful with Wing Chun sensitivity, that is what is in the Praying Mantis Style.
Stepping outside the Shaolin influence, one comes to Tai Chi Chuan (Taiji Quan), which is a Wudan based art. This art practices whole body sensitivity, and is considered by many to be the peak of martial arts expression in the world. By 'emptying' the body one enables the body to generate massive amounts of 'Chi Energy,' and this energy is far beyond simple muscle and sinew.
A more rare form of Wudan Mountain Art is the style known as Pa Kua Chang (Baguazhang). This is a circular art designed to undulate and slither, and leave an attacker in a state of confusion. As in Tai Chi, Chi Energy are generated, but by the unique training method called 'Walking the Circle.'
Five deadly arts, each of which is totally devastating, has unique lineage, and has been proven over thousands of years. And, there are deviations and variations of these styles which are amazingly powerful in their own right. Indeed, to know even one of the Five Incredibly Deadly Kung Fu Styles is to take control of your world, and the entire world, and many people specialize in more than one, blending the arts in a form of self expression far beyond the mere mortal.
