  • The Spleen has major collaterals distributing on the side of the trunk.
  • Also, the Du and Ren meridians have their collaterals respectively. The Du collateral distributes on the back and the Ren on the abdomen.
  • Each of the collaterals has a Luo-connecting point pertaining to the meridian from which it derives.
