Si Yuan is a global community of Dr. Tan’s Balance Method experts, passionately committed to preserving its authentic transmission and evolution while honoring the spirit of its founder.
“任重道遠 (ren zhong dao yuan) – The task is arduous, and the path is long.” These were among Dr. Tan’s final words as he entrusted his three apprentices—Dr. Delphine Armand, Eileen Han, and Paul Wang—with the responsibility of continuing his legacy. Their mission is not only to share his teachings on Acupuncture, Self-Culture, and Ba Zi but, more importantly, to uphold the profound wisdom that lies at the heart of true balance.
Si Yuan was founded in 2015 in Dr. Tan’s native Taiwan, shortly after his passing. It was established by his two closest disciples, Dr. Delphine Armand and Eileen Han, with the support of Paul Wang.
The name “Si Yuan” originates from the classical Chinese proverb 飲水思源 (Yǐn Shui Si Yuan)—“When you drink water, remember its source.”
Dr. Tan left a profound impact on thousands of acupuncturists worldwide with his genius, charisma, humor, and generosity. Si Yuan serves as a tribute to his legacy, reminding us that behind every successful treatment lies a lifetime of dedication to revolutionizing the practice of acupuncture.
At Si Yuan, we are committed to:
Providing practical teaching, delivered with care by skilled and experienced practitioners.
Fostering creativity and continuous self-improvement—as teachers, therapists, and individuals.
Offering training, workshops, and treatments that are inclusive as they are adaptable to diverse cultures and communities.
A chance encounter with my Shifu (Master) during a thesis internship in Germany changed the course of my professional life. I invested all my student savings to attend his next seminar.
The logic and effectiveness of the Balance Method inspired me to dedicate myself fully to its practice and international expansion. I had the privilege of working alongside Dr. Tan for nearly ten years, during which I gained invaluable knowledge—not only about Chinese medicine but also about life itself. I had the honor of assisting him at numerous conferences and training courses across America, Europe, Australia, and Asia, observing his practice and welcoming him to mine— a place where, as he used to say, “the fast trains don’t even stop.” I organized and translated his training courses into French worldwide and also translated one of his books. I studied Ba Zi with him and assisted in preparing analyses for his clients. Since 2008, I have exclusively practiced Dr. Tan’s Balance Method. I have led workshops and taught courses whenever his health prevented him from attending.
At his request, and since his passing in 2015, I have continued to carry forward his teachings, spirit, and values through international and online training courses, conferences, and workshops.
