 Of course, actually, all the kung fu can be used to self-defense. What you mentioned, some looks like kung fu, actually it's called wu shu or something like kung fu dancing. It's different from the kung fu. That's just for the stage performance, just like gymnastics, or the low-level gymnastics. But all the kung fu including prime man is the purpose to have the form to record the fighting concept or techniques in the form. Because before we don't have the YouTube videos, we cannot record all the techniques. So the creators just make the techniques or concepts, combine it into the forms. And then from the forms can pass down by the generations. But you need to decode the concept inside. Some people will misunderstand it, some movements, they don't know how to use it. But I'm lucky, I'm fortunate, I can decode these techniques from my seafoods. So that's why I want to share it with you guys. Prime Man is some of the movements for the self-defense, some for the stage fighting, or some for the street fighting. That's a different concept. For example, for this movement, this movement is not for the stage fighting. But it's good for the street fighting or some people want to bully you. If you are a girl, some people want to bully you. Okay, I want to bully you, no. This is stage fighting. We all go to the fighting positions. But in the street, some people just want to push you. At this time, you can grab him and dislocate his shoulders. Or make him shock. This is a different concept. For example, we have this one, we hit the eyeball, but it's illegal in the stage fighting. You can't do it in stage fighting, you mean sports, right? Competitive. Competitive. But this is for the real self-defense. So in Mantis, there are many illegal moves you cannot use in sports. No. Because it's used for the street. Street fighting, no. Total different concept. But you can use some of the techniques in the stage fighting. It depends on how to use it. But sometimes you need to change the movements. So I always focus, emphasize, to tell my students. Pre-Mantis is actually the fighting concept. More important than fighting techniques or the movements. The concept is alive. You can change by the situations. But the techniques or the movements only fit for one situation. It's totally different. So I want to share this knowledge to you in the videos. Thank you. I think Pre-Mantis is just like the Tai Chi or Wing Chun. It's more like the defensive system, not offensive system. So you need to control the enemy first before you launch a strike. So we have the principle in Chinese called Bu Diao Bu Da. When you hook and then punch, to avoid the lucky punches. So you don't punch unless you have a grab person. You need to control the person before you attack. Including the grabbing or go to the very good positions, angles. For example, we're using the parcel. I avoid the punch and then go to the good angle and then to do the striking. Punching, punching is good. Even though you are very good, sometimes you can be beat by the lucky punch. And then you will be OK. That's the idea. But when you control the person, you need to use this timing. We call Fung Diao Bu Da. That means when you hook the person or control him, then you need to launch the striking at once. Don't waste the timing. I think playing man is more... because it combines different styles of the Asian-Chinese martial arts. So when you practice, you feel very fun. Because including the swine king, king, king, long distance, wrestling, joint knocking, it's very fun. There's lots to learn. Yeah, lots to learn. In playing man is, for example, in playing man is, most of the movement, actually, is the concept, not the technique or the single movement. What's the difference? The difference is, for example, like playing man is with the bangle form, the first movement we call Paksou Chong Chui, right? This one. This movement is a technique. When you punch me, I block and then punch you back. Punch you not the head, as you approach the striking point. Punch here. Make your diaphragm sparser. This is the technique. We call it technique of the movement. But from this one, we can see the concept inside. You can change all the time. For this movement, we have blocking, avoiding, at the same time punching. This is the concept. So we can change. Also, blocking. But this time I hit your head, uppercut. Blocking. Blocking gives you a bangchui. It all belongs to this concept. So the concept inside can change. To fit the situations, the real situations, but not the fixed movements. This is different. Yeah, change. It depends on the situation. Depends on the situation. Because in the fight, nothing is always the same. No, no. So when we train my students, I always use the concept. And then use some target to let him have a different situation to get the response. When you have the response, that means the kung fu becomes your body. Go to your body. Internalize. Internalize. Not you need to remember, he punched me, I need to block and punch. It's not real. Because you don't have time to think. No, no time. You just make your kung fu become your natural response. That's very important. So that's why you need to learn the concept. Concept and form the response. The good response. Okay.
