Wong Shun Leung (黃淳樑 1935-1997) was considered by many to be "the most famous fighter of the Wing Chun clan in the early 1950's".  Since his reputation was world-wide as a Wing Chun master and a sought after seminar speaker,   Wong Shun Leung had been interviewed many times. Based on information gathered during his various interviews, Wong Shun Leung had expressed his profound knowledge of various aspects of fighting. Today's martial artists can obviously become better fighters if they can fully understand and absorb Wong Shun Leung's profound knowledge of fighting. Following is a small collection of his profound opinions regarding various fighting principles and combat concepts.
- Wong Shun Leung Comments on the Effect of a Punch
- "Wong Shun Leung said that when you punch the head the brain hits the side of the skull. If the brain is against the side of the skull and a second hit follows, then damage and a knockout results because there is no cushioning possible. This is why Wing Chun has its rapid fire punches instead of the pull back approach." 
- Wong Shun Leung Comments on the Chain Punches in Wing Chun
- "In Wing Chun if you throw two fast punches to someone's head they'll be knocked out. The first punch causes the brain to go to one side of the skull. If a quick second hit comes, the person is knocked out. If you withdraw the hand to give the second punch, then the brain can recover (will have more time to recover), but if you don't give this time then a knockout results." 
- Wong Shun Leung's Answer on the Question of "Does Wing Chun ever use fake punches?"
- "No, Wing Chun will never use a fake punch." 
Kicking and Kneeing
- Wong Shun Leung Applied the Principle of a One-Step Action to Execute a Kick
- "Try not to use two actions. Like when kicking, Wing Chun doesn't like to lift the knee first and then kick because this is a two step action. Also the line of force is wrong because your kick will not have ground support. Instead, your kick will transmit back to your body to off-balance you. This is why Yip Man's kick in the second set looks a bit funny at first. We want to travel in a straight line from the ground to the target, not lift the knee first." 
- Wong Shun Leung's Ways to Beat a Good Kicker
- "Against a strong kicker there are two ways to fight. If you are experienced, just go into their center and hit. But if you aren't, then back up. Each time the opponent misses, he will lose one degree of confidence. After a while you have more chances." 
- Wong Shun Leung Comments on How to Defend Against Various Leg Attacks
- "For low side kick attacks, Wong Shun Leung uses the feet. For knee attacks, he said if you hit straight the knee cannot really get you. Against the Thai boxing round kick Wong Shun Leung kicks straight forward, rather than use a clashing force with a Bong leg. This forces the kicker straight back." 
Standing Grappling Situations
- Wong Shun Leung Comments on How to Respond to a Grab
- "If you hold two arms out in front of you and someone grabs them, then you can use the third set elbow movement to escape. Bring the hand right in to touch the body. If the hand is held in a fist, it doesn't work. Then press down with the elbow. " 
- Wong Shun Leung's Way to Escape from a Rear Arm Lock
- "To escape from a rear arm lock, straighten the arm by choosing the best line of force. The hand turns and goes in an upward direction. Then step in and unbalance the opponent." 
- Wong Shun Leung's Answer on the Question of "From the fights that you had, did you find that you needed to fight on the ground?"
- "The situation where you need to wrestle is when both opponents want to grab. Western boxing is supposed to be hitting, but you still see situations where they want to hold on to each other. This is because one of them is scared. If you are scared then you will try to hold onto your opponent. It is very difficult for someone to lock or hold onto you if you know Wing Chun. You can stop the other guy holding or grabbing. If someone grabs you, you will only try to grab back if you are scared. But if you are not scared, then he cannot force you into a wrestling situation." 
- Wong Shun Leung's Answer on the Question of "If you trip and end up on the floor, can you still apply the principles of Wing Chun?"
- "This situation can happen to anyone. If you learn Wing Chun you can cope with it better than someone that doesn't know Wing Chun." 
Mixed Martial Arts
- Wong Shun Leung's Answer on the Question of "Do you feel that Ving Tsun (Wing Chun) has any limitations ? Many students like to combine boxing with kicking , throwing and grappling on the ground to develop eclectic systems."
- "In training Biu Jee we are taught to be free . The first forms tell us about normal situations. Biu Jee is for the abnormal situations . The ideas in Biu Jee sometimes will contradict normal Ving Tsun (Wing Chun) ideas in order to allow the person to survive in a bad situation . We are told to do what is necessary to survive and so there are no limitations . Styles have different concepts and objectives . With Ving Tsun (Wing Chun) we want to attack our opponent in a very direct and savage manner . Other styles will contradict this objective by attempting non-direct tactics . If we combine them our objectives can become confused in the heat of the fight . We will be less effective ." 
How to Train Mentally and Physically for Matches Against Other Styles
- Wong Shun Leung's Answer on the Question of "How did you train mentally and physically for your matches against other styles?"
- "For such a fight, you must train hard to just develop the self confidence to enter such a match . You must, by way of your self confidence, know that you can win . When Ving Tsun (Wing Chun) practitioners go to fight and are defeated then the mentality is not to think that the other person is better than himself . Instead he needs to ask himself what were his mistakes to invite the attack . This is the kind of positive thinking which any fighter must possess." 
Practical Fighting Concepts
- Wong Shun Leung Comments on Where to Hit on the Human Head
- "In Wing Chun we hit the larger part of the face, usually at an angle, so the butt of the chin is avoided. In Wing Chun, the main target area is from the mouth upward..." 
- Wong Shun Leung: "Your hand is able to reach your opponent long before your foot."
- "I think the kicks in Wing Chun are enough. It´s much easier to use your hands than to use your feet. Your hand is able to reach your opponent long before your foot. Why take the long way to attack (circle), when there is a much more direct method of attack? If you are using your hands, then your opponent can´t see a kick coming if you have to use it. When you teach Kung Fu, you can fool a lot of people, but not yourself. You can make like a movie and do many complicated movements and kicks, but you only fool yourself as to whether that would work in a real situation of life and death." 
- "Boxing moves the head to dodge punches, but in Wing Chun we don't, because the head can't be faster than the hand." 
- "In boxing, the style has changed over the years from crouching to being more and more vertical. Also people used to jump around, but the modern boxer like Tyson just moves in flat footed to demolish his opponent in a scientific way. In Wing Chun a person does not bob as in boxing. When two beginners fight it doesn't matter how they fight, but against professionals it makes a difference. Even a smaller [person] is better off to keep the body vertical and step back, then to bob and weave. This is because the hand can move faster than the body. Boxing is still like a game because there are rules for how you can hit and how you can't hit. If you attack someone and they bend their head, then in Wing Chun you can still hit them with your hand even without pulling your hand back." 
- "The late Sifu Wong Shun Leung, of “Hong Kong” wing chun fame, in his seminars around the world over the years, liked to make a comparison with the modern combat sport of Western boxing, which he observed had changed quite dramatically over just the last sixty or so years, from the crouching-like postures of boxers like Joe Louis in the 30s and 40s, to the flashy footwork of the likes of Muhammad Ali in the 60s and 70s, through to the more upright and flat-footed approach of recent champions such as Mike Tyson."
