Confirmed by thermal sensitive moxibustion in clinic, Qijie is revealed to be one of the running laws of meridian qi and the sagittal pathways of the major passages for qi circulation. It is taken as the essential content of the direct pathway for negotiating the superficial part of the body and the intra-organism tissues as well as zang-fu organs.
