    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).

    Tung's Behind the Heart (Hou Xin or Bei Xin) points are located under spinous processes from T4 to T9, 1.5 cun laterally to T4 to T7 and 3 cun laterally from T4 to T6. They are indicated for "wool like furuncles", clove sores, weakness and debility of the Heart zang, Stomach diseases, acute heart disease leading to numbness and paralysis, wind-cold entering the interior, severe wind-cold, stroke, externally contracted diseases that manifest with papules. They clear heat from the Heart and Lung and release the exterior so are useful in dermatological disorders (ibid.).
