The Eight Meeting Points or Converging Points (ba hui xue, ba hui) refers to the eight acu-moxa locations where the eight kinds of essential Qi - zang, fu, Qi, blood, tendons, mai Vessels, bone and marrow -- are focused. Fu converges at the taicang (Great Granary) point (here this indicates the zhongwan (Middle Cavity) point); zang converges at the jixie point (location corresponding to the cartilage of the 11th and 12th ribs, here indicating zhangmen, Completion Portal); the tendons converge at the yanglingquan (Yang Mound Spring) point; marrow converges at the juegu (Severed Bone) point; blood converges at the geshu (Diaphragm Conveyor) point; bone converges at the dazhu (Great Shuttle) point; the mai Vessels converge at the taiyuan (Great Abyss) point; and Qi converges in the sanjiao (Triple Burner) (i.e danzhong, Chest Centre).
