Fourth, we can touch meridians
Each acupoint, which is at interconnecting fringe area or dorso-ventral boundary and the junction of different fascia connective tissue network, is the channel for exogenous evil entering and being cleared. One can press acupoints and feel the energy transmission of meridians.
Yanglingquan(GB34)(Fig.1), the Sea acupoint of Gallbladder meridian, is located at fringe depression, where the connective tissue interconnects above the deep fibular periosteum, below fibular head between ligament and head of fibula. To press Yanglingquan to Deqi(acupoint breath) state, adjusting the breath and inward feeling the meridian, one can feel Gallbladder meridian subtle energy pulse through the skin surface.
