    Notes:
    In Master Tung's system a line of points corresponding to the inner back Shu points from T2 to T8, known as the double phoenix points (Shuang Feng), can be pricked to release a drop of blood in cases of pain or numbness in the extremities or arteriosclerosis.
    They all relate to the Fire element and the Heart and so have the function of quickening the Blood in the Heart and the extremities (McCann, 2014, Pricking the Vessels).
