Through the transformative practices of Tai Chi Chuan, Chi Kung, Nei Kung, Nei Dan, and Martial Arts, he aims to provide a structured yet profound path of self-mastery, balance, and inner cultivation.
At the core of this vision is the understanding that all sentient beings, non-living forces, and the universe are intrinsically connected. Sifu Sahu seeks to guide students toward the realisation of their True Nature, the Nature of Reality, and the state of No Mind, aligning with the wisdom of the ancients. Through this journey, practitioners transcend limitations, embody universal principles, cultivate harmony within themselves, and the world around them.
This school has transformed not only how I move, but how I understand my body, my mind, and my place in the world.

ABOUT THE
Ptah khi Principal
Over 25 years ago, Sifu Sahu began a journey into the internal arts. A journey that transformed not only the way he moved, but the way he understood the relationship between the body, mind, health, and human potential.
Through years of dedicated practice, study, and teaching, he discovered that Tai Chi and Chi Kung are far more than physical movements. They represent a complete system of internal development to refine the body, regulating the breath, cultivating energy, expanding awareness, and developing deeper understanding of ourselves.
Principal’s Background
Principal and Head Coach Sifu Sahu Tao Shen is a recognised holistic health practitioner with over 25 years of clinical and movement-based experience, specialising in musculoskeletal therapy, Chi Kung, and Tai Chi. As the founder of JusTouch Therapy (est. 2006), he has supported the rehabilitation, functional recovery, and long-term wellbeing of individuals across a wide range of communities and health needs.
Sifu Sahu’s journey began in 2004 with Chi Kung and expanded in 2007 through Tai Chi training under Grand Master Amun Ka El. In 2015, he became Principal and Head Coach of the Ptah Khi School, where he has guided students through the progressive stages of training from foundation practice to 1st degree black sash level and beyond maintaining the values of discipline, integrity, awareness, and excellence.
He has also contributed to the wider martial arts community as a judge at the BCCMA National Championships in 2023, overseeing Tai Chi Chuan, Xing Yi Quan, Bagua Zhang, and Weapons Forms, and again in 2025 and 2026 as an official Tui Shou Judge. Under his leadership, the Ptah Khi School has achieved national competition success, including multiple medals and gold medal achievements.
Sifu Sahu is officially recognised and certified to teach Tai Chi, Chi Kung, Nei Kung, Nei Dan, and internal martial arts in the UK and internationally. He is a registered Commercial Instructor with the British Council for Chinese Martial Arts (BCCMA), an Instructor Member of the Tai Chi Union for Great Britain (TCUGB), and an accredited MCIMSPA Tai Chi for Health & Well-Being Practitioner with CIMSPA.

These recognised standards reflect his commitment to safe, professional, and high-quality instruction, while preserving the depth and integrity of internal arts.
Today, the Ptah Khi School continues to share this complete system of internal development of connecting traditional wisdom, modern understanding, and the journey towards greater awareness and mastery.
His teachings blend Tai Chi, Chi Kung, Nei Kung, Nei Dan, and holistic therapies to support recovery, functional improvement, and wellbeing for all practitioners.

Health and longevity Programme
Health & Longevity Programme
A Pathway to Cultivating Vitality, Balance, and Conscious Living
The Health & Longevity Programme represents the integration of ancient internal arts wisdom with modern approaches to wellbeing, movement, and human performance.
Through the practices of Tai Chi, Chi Kung, breathwork, meditation, and internal cultivation, this programme explores the foundations that support a healthier relationship between the body, mind, and the deeper aspects of our being.
Rather than focusing only on the idea of adding more years to life, Health & Longevity explores how we can develop greater quality, awareness, and vitality within each moment — cultivating resilience, emotional balance, physical harmony, and a deeper connection with ourselves and the world around us.
Drawing from the Ptah Khi School system of internal development, the programme provides practical methods for improving movement, breathing, relaxation, mindfulness, and self-awareness, creating a foundation for lifelong growth and wellbeing.

This course is your path to internal precision, resilience, and insight, perfectly complementing the Health & Longevity Program and unlocking the full potential of your internal world.

Discover a wondrous path within the Nei Dan course at Ptah Khi School, where the ancient art of inner alchemy guides you through three sacred levels, awakening body, mind, and spirit in harmonious union with the cosmos. This path unveils the Three Treasures: Jing, Chi, and Shen. As stages of refinement lead to profound mastery. In the Lower Dantien, known as Harmonizing and Refining the Five Elements, you will gather the deep, grounding energies of the earth, forging a stable foundation for inner transformation.
As you ascend, you enter the Middle Dantien, or Balancing the Heart and Earth Energies, a journey into the mystical union of heart and earth, creating harmony within the emotional and energetic realms. Finally, in the Upper Dantien, also known as Cultivating the Crystal Room, you awaken the luminous clarity of the mind’s eye, connecting with the subtle realm of insight and expanded awareness. These online course are a sanctuary for those ready to unlock their highest potential, offering a pathway to connect deeply with the Three Treasures, embracing a radiant balance that transcends the ordinary.

The 369 System
