The present disclosure relates to an acupuncture meridian measurement system. The acupuncture meridian measurement system comprises: a signal generator configured to generate an alternating current excitation signal; an impedance measurer coupled to the signal generator and configured to measure a biological impedance between a fixed point to be measured and at least one selected point of an object; an acupuncture point determiner coupled to the impedance measurer and configured to locate an acupuncture point based on the measured biological impedance, wherein, the determined acupuncture point is a selected point, the biological impedance between which and the fixed point is less than a threshold. A technical problem solved by an embodiment of the present disclosure is to realize an accurate location of the acupuncture meridian. A use of an embodiment of the present disclosure is to locate acupuncture meridian and Yuan acupuncture points.
