Rugen (ST-18) emerges below the nipple. These five acupoints are each one cun and six fen apart. Burong (ST-19) is adjacent to Youmen (CV-15) by one cun and five fen. Chengman (ST-20), Liangmen (ST-21), and Guanmen (ST-22) follow. Taiyi (ST-23) is arranged next to Hairoumen (ST-24). Each separated by one cun, the acupoints are complete.
