About Si Yuan

In January 2016, three close apprentices of the late Dr. Richard Tehfu Tan, who had worked with him for over a decade, founded Si Yuan. While too generous to let the transmission of his Balance Method end with him, Dr. Tan also knew that his life mission could not be responsibly left in the hands of inexperienced or untrained apprentices.

“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.

At the end of 2018, following their unique backgrounds, values, priorities, and dreams, the three official lineage transmitters of Dr. Tan’s Balance Method stepped forward to offer two different learning environments.  Believing in the values founded in Si Yuan, Dr. Delphine Armand and Dr. Paul Wang continue to transmit the wisdom and knowledge passed on by their honored teacher.

Si Yuan Team

Si Yuan Instructors are :

Balance Method acupuncturists with more than ten years’ experience practicing in high-volume community acupuncture settings.

  • 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.
