Wing Chun is a Chinese system of self-protection; its design is based on angles and body mechanics, maximizing the strength and effectiveness of its methods. Wing Chun actions have the unique characteristic of defending and counter-attacking simultaneously. Wing Chun's strength is in being simple, direct and efficient.

“As long as it stays logical, it doesn't matter what you call it or what you’re actually doing. 
If it is logical, if it works, use it!”

-Sigung Wong Shun Leung
