Abstract：The main etiology and pathogenesis of stiff neck is that the wind，cold and other external pathogens invade the neck，block meridians and collaterals，and damage the meridians and tendons. This leads to local coagulation and stagnation of qi and blood， whose blockage results in pain. Stiff neck is commonly an acute onset， whose nature is mainly excess syndrome and location is at the hand taiyang small intestine meridian. Tianzong point (SI11) belongs to both the hand taiyang small intestine meridian and the Ashi point. The acupuncture at this point can quickly play the role of relaxing the sinews and unblocking the collateralss，dispelling wind and dissipating cold，and invigorating blood and relieving pain. In this way， the spasm of the back neck muscles is relieved，the pain is reduced，and the active neck function is quickly restored.
