From there it runs still further downwards to the forearm between the tendons of m. palmaris longus and m. flexorcarpi,and enters the palm.It runs along the middle finger to its tip(Point Zhongchong,PC9).
Another branch of its leaves the palm(Point Laogong,PC8),runs along the ring finger to its tip(Point Guanchong,SJ1),and connects with the Triple Warmer Channel of Hand-Shaoyang.
