[Vicissitude and enlightenment of Bonghan theory]

Dr. KIM Bonghan in North Korea in 1963 proclaimed that he discovered the physical structure of the acupoints and meridian systems which were corresponding to the Bonghan Corpuscles and Bonghan Ducts. The original discovery could not be replicated by other international researchers; therefore, it was neglected as a pseudoscience for years. This paper reviewed the relevant literatures which were published in the past 40 years, stated the findings published by Satoru Fujiwara A and Kwang-sup SOH and his colleagues. This paper also presented the perspective in meridian research after the Bonghan theory was proposed.
