 For example, for me, I learned from this form when I was four years old, very small and very young ages. I also have many students from different ages. One of my students, she just got a silver medal in the International Kung Fu Competition. She is over 60 years old. 60 years old? Yeah, just for her only half a year to train. So, I think, so anybody, no matter you are a girl or a boy, a fat or skinny or young kids or the old guys, all can learn the parameters for fun, for health and for self-defense. If you want to learn from the videos, I think one to three months you can learn one form. For example, the bumble form, you can learn just, depends on how many times you spend in one day or one month, right? But normally, the faster one, I think one month. If you learn it and practice every day, one month is enough for the parameters for fun. Some people, they don't have enough time, they need to go to the busy job, so they need three months, depends. So, for one to three months, we can learn the bumble, not this far. Yeah. So, this form translated is an explosive step. Yes, because we have some special striking techniques called bun chui. And the step is very fast, so we call bun bo. I see. Yeah. Okay. So, the first one, of course, you can master some of the techniques or concepts of the self-defense. The second one can help you make you more agile, you're responsible more faster than before. And also, can strengthen all your bodies, including the joints, muscles. It's very good for your health and self-defense. In Mandarin, cha chui, bun bu do ka. So, I will want to teach the bun bo first. Bun bo is a very famous play-play mantis form. Bun bo means explosive step. Yes. Very famous play-play mantis form. No matter the seven stars or the tai chi play mantis or other play mantis, they all have this kind of beginning form. So, this form, why is it called the beginning form? Because the steps still not go to the monkey stance. They are also the foundations. Bow stance, cat stance, horse stance. But in the middle forms, the techniques, the combos are more complicated. And for the advanced form, the footwork, just like the fighting footwork, no horse stance, bow stance or something. It's called yu huan bu or monkey stance. Very agile, very reality in the real fighting. Cha chui and other... Piercing hammer. Yes. And this cha chui is also the foundation for foundations. But these foundations are very practical, actually. Each movement has the fighting concept inside. At the same time, it can help you to practice your coordination. Improve your coordination. Okay. Do gong. Do gong. Do gong. Some people want to learn do gong. Evading force. Evading force. If you like it, if you want to learn, just skip to the middle form. Lan jie. What's lan jie? Lan jie is the... Lan is block. Jie is just like jikun dong. Lan jie. Intercepting block. Okay, like that. From this form, many special combos, wrestling, combined, the first time you can see the takedowns. Some striking is for takedowns. Some takedown is for striking. So blending, striking and takedown and wrestling together. Yeah. Okay.
