About Si Yuan

“任重道遠 The task is arduous and the road is long” were some of Dr. Tan’s final words when entrusting his three apprentices to continue sharing — not only his Acupuncture, Cultivation, and Bazi teachings — but also the deep wisdom at the core of any true balance.

Si Yuan Team

Instructors :

With over 10 years' experience as Dr. Tan's closest apprentices, they were entrusted by the Grand Master to transmit the wisdom and knowledge passed on by their honored teacher.

  • Dr. Delphine Armand, LAc, DVM

    continuously worked by her Master’s side as an assistant at classes, an intern in his clinic and as a French translator during live seminars.


    Dr. Delphine Armand’s introduction and immersion in the Balance Method is proof that life can change in the blink of an eye. She first met her Shifu (Master) while interning and working on her dissertation in Germany. Astonished by his charismatic and fun personality, and intrigued by the strange broken and unbroken lines (trigrams) he had drawn on her notebook, she decided to invest her entire savings to attend his next scheduled class.

    Dr. Armand was immediately fascinated by the logic and effectiveness of the Balance Method and completely devoted herself to its practice and subsequent international growth.

    In fulfilling this mission, she worked hand in hand with her Mentor for almost a decade.

    Dr. Armand shared with her Shifu a unique connection of “work hard, play hard”. She closely assisted him in countless classes in the United States, Europe, Australia, and Asia and has performed live translations of all of his classes into French, as well as coordinated the French translation of his books. Most recently, she advanced her study of Ba Zi assisting her Professor in the preparation of his client’s charts.

    Starting in 2008, she exclusively practiced his Balance Method in her clinic in France. During this time, he visited her busy practice and oversaw the treatment of her patients. Likewise, Delphine interned in her Master’s San Diego, California clinic on numerous occasions.

    Dr. Delphine Armand holds degrees in both Veterinary Medicine as well as Traditional Chinese Medicine.

  • Dr. Paul Chengpo Wang, LAc, DACM

    is a Doctor of Acupuncture and Chinese Medicine and a practitioner of healing, martial, and energy arts with over twenty years of teaching experience in these fields.


    In 2003, Dr. Paul Wang first met his primary acupuncture Shifu (Master), Dr. Richard Tan, while completing graduate studies in Chinese medicine. Dr. Wang was so immediately and deeply affected by a resonance with his teachings that he instinctively bowed and asked to become his disciple on the spot. In response, the amused lecturer smiled and wittily replied, “Perhaps after a Ba Zi reading.” The rest is history.

    Over the ensuing years, Dr. Wang and his Shifu developed a close spiritual relationship as Master and Apprentice. Aside from a dedication to innovating acupuncture, the pair also shared an intellectual curiosity and systematic creativity — as well as a passion for good food and fine wine.

    For more than a decade, Dr. Paul Wang honed his skills in the Balance Method as a California Licensed Acupuncturist practicing in a high-volume community acupuncture setting. He also completed training and certification in his Shifu’s Ba Zi course.

    Prior to initiating professional practice, Dr. Wang was a Regents’ and Chancellor’s Scholar at the University of California at Berkeley and an Undergraduate Research Apprentice in the Poly-PEDAL laboratory of Professor Robert J. Full. He holds a Bachelor of Arts degree in Integrative Biology with an emphasis in Physiology and Biomechanics from the University of California at Berkeley. He also pursued minor studies in Classical Chinese and East Asian Philosophy, especially Daoism. His graduate degrees are a Master of Science in Traditional Chinese Medicine (MSTCM) and a Doctorate of Acupuncture and Chinese Medicine (DACM).

    Dr. Wang has over two decades of experience in various teaching capacities. As an avid martial artist, qi cultivator, and long-term meditator, he merges these lineages into an integrative transmission called Dao De Gong Fa.

  • Silvia del Conte, Lic. Ac.

    Italian communications contact and social media

    The first time I heard about Dr. Tan was in Beijing, while studying Chinese Medicine at university. At the university, I met someone who explained his method to us. I found it so clear and useful to grasp the core of the treatment that I started using his reasoning and applied it to patients in China. It was so effective that I decided to join a class when he was teaching in London. I was very lucky to have met Dr. Tan in person before he left us. He gave me the perception that acupuncture is a system of dealing with living organisms and interactions and that we all are connected in a Matrix. He touched my heart with his passion and profound love for his tradition and students. Silvia contributes to Si Yuan by translating the Italian webpages and contributing to social media.
