Illustration from an edition of the Wanli reign period of the Ming dynasty (1573-1620). The image charts the disorders associated with the three pulse sectors of the left wrist - cunkou, guanzhong and chixia; i.e. the cunkou pulse of the left wrist is associated with the heart and small intestine, the guanzhong pulse of the left wrist is associated with the liver and gall bladder, and the chixia pulse of the left wrist is associated with the kidney and bladder. One fen (c. 0.3 cm) from the wrist joint is the location for palpating the renying (Human Welcome) pulse.
