The Inner Door · 門內
Watching videos makes you a viewer.
Stepping through the inner door makes you a student.
Every practitioner in this lineage trains inside one system — Shishou (師匠), our inner-door home. It’s where your training stops being scattered clips and becomes a mapped, tracked, personal path with a teacher who remembers where you are.
The full transmission map
The complete Yizong curriculum — 11 gates, 74 forms, from basic hands through the palm changes, the pre-heaven palms, the 64 palms, weapons and more. Always know exactly where you are and what comes next. See the roadmap →
A ranked knowledge base
Not a random video pile — a graded curriculum that unlocks as you progress (entry → 1st dan → 2nd → 3rd). Each rank opens the next body of material: the 64 palms, the five-element fists, push-hands, weapons, internal method.
Your practice, tracked
Log your training, watch your progress, see your rank and your current focus. The relationship is recorded — nothing gets lost between lessons.

Training in Taiwan?
The Inner Door also runs the real school — weekly classes in Taipei (Da’an) and Zhubei (Bagua foundations & advanced, Xingyi, weapons, push-hands, intro trials), plus seminars. Every enrolled student gets Inner Door access: your map, your rank, your record.
