What Demon Slayer Gets Right About Real Swordsmanship

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.
