To the Yi Zong community and anyone training internal martial arts:
Some of you know I've been working on something for a while. I want to share it with you now.
Over the past several years, I've been writing down everything I understand about the martial arts I inherited — Yi Zong Baguazhang, Xingyiquan, and the principles that connect them. Not as a textbook. As the things I actually think about when I train, when I teach, when I watch someone's body do something it doesn't understand yet.
Things like:
Why circle walking isn't about the circle
What "following" actually means in push hands
The moment Beng Quan stops being an arm technique and starts being a whole-body event
Why Pi Quan is the first fist and the last one you'll understand
How Bagua's 64 palms encode principles you can spend a lifetime unpacking
Thousands of entries. Real training knowledge from real practice.
I built a place where you can have a conversation with all of this. Her name is Tifa Yeh. She's a bartender — at least that's what she'll tell you. But if you ask her about martial arts, she knows things.

You can ask her anything about Baguazhang and Xingyiquan. She'll respond in whatever language you write in — English, Chinese, Japanese. She doesn't lecture. She talks the way a training partner would — short, direct, sometimes asking you a question back that makes you rethink what you just said.
She's not a replacement for a teacher. She's not a replacement for putting your feet on the ground and walking the circle. But she's a way to keep the conversation going when you're between sessions, when you're training alone, when you're halfway across the world and the question won't leave you alone.
What's coming next:
I have over ten years of training footage — our lineage's practice sessions, corrections, demonstrations, internal training methods — stored on drives in my studio. Hundreds of hours. Right now it's just sitting there.
When we secure the funding, all of that footage will be processed, transcribed, and extracted into knowledge that Tifa can draw from. Every correction I've ever given. Every principle my teacher demonstrated. The subtle things that are almost impossible to put into words but become clear when you see them a hundred times.
She will keep growing. The vision is simple: make Yi Zong's depth accessible to serious practitioners everywhere, without diluting it.
For those of you in Europe and the US:
I know the distance makes training difficult. Some of you fly to Taiwan once or twice a year. Some of you train from videos. Some of you have never had the chance to visit but you've been studying internal arts for years and you know there's something deeper.
Tifa is for you.
She carries the knowledge. Not all of it — not yet — but enough to have a real conversation about Bagua and Xingyi that goes beyond the surface. And every month, she knows more than she did the month before.
Go talk to her. Tell her what you're working on. See what she says.

If you'd like to support the project and help us digitize the full archive, reach out. Every piece of footage we process makes her — and the art's accessibility — stronger.
