RESUMEN
To summarize professor SUN Xuequan's own experience on the acupuncture sensation. Professor SUN Xuequan puts forward his opinion through the sensation of acupuncture on himself, from the aspects of the expression, the material basis, the distinction and the clinical significance of acupuncture sensation, etc. Professor SUN thinks that the production and conduction direction of acupuncture sensation have their material basis and objectively exist, based on which, professor SUN puts forward the amount of acupuncture stimulation and the total amount of acupuncture stimulation. Professor SUN believes that the amount of acupuncture stimulation is the main basis for the individual reinforcing and reducing of acupuncture. The amount of acupuncture stimulation is related to the depth and intensity of acupuncture, the time of the needle retention, the number of needles, etc. The reinforcing and reducing of acupuncture are relative to the deficiency and excess of the disease, and they are the reaction of acupuncture for body. The tolerance degree of the individual to the stimulation of acupuncture is also the main factor affecting the reinforcing and reducing.
