What am I busy for:

Recently I’ve been asked to introduce myself quite often, so I decided to put everything together here.

What I’m working on now can be divided into three main directions:

① Online Course Total Solution

This is a system I’ve been developing over the past few years, and it includes three major parts:

1. 360° panoramic filming

Traditional teaching videos always have blind spots—sometimes the teacher’s body blocks the blackboard, or when the teacher turns around, you can’t see their hands at all.

With 360° panoramic filming, we break this spatial limitation. Students can freely shift their perspective and focus exactly where they want.

The prototype is done; now we are working on improving resolution and smoother online streaming.

2. Automatic video segmentation and summarization

Nobody can sit through a two-hour course video.

So our system automatically cuts a long video into 1–3 minute clips with summaries attached.

When a student wants to review, they can simply type a keyword like “baseball swing hand posture”, and the system will instantly bring up the exact clip they need.

Think of it this way: a whole pizza is too much to finish, so I cut it into smaller slices for you. And if you only want lobster or scallops on top, I’ll pick them out for you directly.

On top of that, the system can also generate personalized 15-second highlights for every student in the class.

If there are ten students, the system creates ten different highlight reels—perfect for them to share on social media. For teachers, this becomes both a review tool and a natural way to promote their classes.

We’ve already submitted this project to the government’s SBIR innovation grant. Results will be announced in early September. Regardless of the outcome, development will continue, and we aim to launch by June–July next year.

3. AI translation

This function translates the course from Chinese into other languages, not just with subtitles, but also by cloning the teacher’s own voice and syncing with their lip movements.

Imagine teaching Linear Algebra to kids in Africa, in their local language, using your own voice—that’s what this system can achieve.

We are still improving speed and efficiency, but the foundation is there.

And here’s another important point: this system can be a huge help for rural education and vocational training.

Kids in remote areas rarely have the chance to learn directly from world-class masters.

We’re not here to replace local teachers, but to give kids the chance to see how the masters really do it—from every angle.

Human beings originally learned through watching movements and images with their eyes. Later, we turned these into words and books. But when it’s time to review or apply the knowledge, the brain has to convert those words back into images again. Not everyone’s brain is good at that.

Video solves this problem.

Take car repair or bicycle maintenance as an example: in the video you can see exactly where the left hand goes, how it holds the part, where the right hand applies force. Just by watching, kids can imitate directly. No complicated conversions needed.

And because video clips can be replayed again and again, from multiple angles, students naturally build progress and confidence. That sense of achievement keeps them motivated to continue.

For vocational education, this is extremely powerful—it saves time, removes unnecessary barriers, and makes learning much more effective.

So this system is not only for big city tutoring centers; it’s also a way to make education more fair and accessible for kids in rural areas.

② Martial Arts Teaching

Martial arts is my foundation and the thing I’ve invested the most of my life in.

I’ve poured countless hours, energy, and unimaginable amounts of money into my training.

Every single part of my martial art is already the essence—there’s no such thing as “extracting highlights.”

People say I’m good at using analogies to explain difficult concepts in simple words.

But the side effect is: people who have never “hit a wall” elsewhere often fail to appreciate it.

Without comparison, they don’t recognize the value.

That’s why I’ve decided to focus my teaching on athletes and coaches.

My website is in English only, because foreign students tend to be more pragmatic—

they’ve struggled enough elsewhere to recognize quality when they see it.

We are also preparing international certification programs, with my teacher’s approval.

All exams will be conducted in English, even for Taiwanese students.

The only difference is that Taiwanese students have the advantage of being able to learn with me in person.

Sometimes people ask: “Why not organize a trial class?”

I’ve tried. Eight people sign up, zero show up.

That made me realize—something this high-level shouldn’t be promoted by begging people to “try it out for free.”

I don’t mind serving premium Wagyu beef in a lunch box at street prices, so people can taste what real quality is.

But what I cannot accept is giving out Wagyu and having people complain, “This meat is too fatty.”

If someone has no comparison, no experience of struggle, and no sense of appreciation—then they were never meant to receive high-level things.

So I know very well: top-tier martial arts doesn’t make big money.

That’s why I built the online teaching system—martial arts is my boutique, but the system is my business.

③ Pet Care Brand

Lastly, there’s a third line I’m working on: a pet care product brand.

This was an unexpected direction, but I don’t believe I can’t do it.

After all, I have over a decade of experience in the pharmaceutical field, and this background transfers naturally into developing safe and reliable pet care solutions.

I won’t go into too much detail here, but it’s something I’m steadily building alongside the other projects.

At first glance, these three directions may seem far apart.

But to me, the core is the same: professionalism, quality, and systemization.

This is what I’ve been busy with recently.

If any of these directions resonate with you—whether collaboration, investment, or simply sharing thoughts—

I’d be more than happy to connect.

Your support helps us continue documenting rare martial arts systems and sharing them with the global community. Whether you’re a student, coach, or fellow researcher — every contribution helps us go further.

Chang Wenteng is the senior student and last indoor disciple of Luo Dexiu, founder of Yizong Baguazhang. For nearly 15 years, he has engaged in intensive weekly private study under Master Luo, developing a refined understanding of internal mechanics, structural alignment, and movement strategy. Graduating with a degree in Physics from National Chiao Tung University, Wenteng applies a systems-level analytical approach to martial practice—decoding principles through the lens of force dynamics and structural mechanics. This scientific foundation enables him to bridge traditional martial concepts with clear, functional explanations. His martial experience spans disciplines, from Yagyu Shinkage-ryu swordsmanship to MMA competition, demonstrating his ability to adapt and integrate core principles across diverse systems. Wenteng’s teaching transcends stylistic boundaries. He focuses on shared internal principles that hold true regardless of form or lineage, helping practitioners develop proprioception, timing, and multi-joint coordination. His method is grounded in sensory clarity and technical simplicity, guiding students toward profound functional insight and cross-system coherence. Rather than promoting stylized movement or emotional narratives, Wenteng’s work emphasizes applicable, real-world skill—the transmission of embodied knowledge through dedicated practice.
