Just in time for Leap Day, this is the first in a series of articles that my mentor Dr. Kezhen Zhang of Beijing Tai Ji Tang Traditional Chinese Medicine Hospital will write about the Meridian System in Traditional Chinese Medicine and published in Acupuncture Today. I'm honored to be his translator for these articles and I hope that his revolutionary ideas will help the TCM professionals and the scientific research community take a second look at existing experimental design for research into the Meridian system.
