ABSTRACT
By analyzing the acupuncture clinical thinking polymorphism in the ancient and modern time，it is shown that the guidance theory systems of acupuncture and moxibustion therapy are on the diversity. Classic meridian system is part of the important composition of acupuncture theory system，and it is not the only one guidance for clinical acupuncture. In the ancient time, acupoints were according to local lesion, classical meridian therory, acupoint indication and effect, the disease, the syndrome, cold-hot and deficiency-excess features, pulse, time and season, meridian's - , and needling instrument, etc. In the modern clinical practice, the points are selected according to the above theories and the modern theories such as western medicine anatomy，as well as various micro-acupuncture systems and the new method theories. Through the analysis of the diversity of ancient and modern acupuncture theory, a preliminary idea of the acupuncture-moxibustion theory system is suggested including traditional theory system (classical meridian system, classical non-meridian system and classical TCM system), and modern theory system [nervous system (linear contact system) and non-nervous system (nonlinear contact system)].
