    Ling Shu Ch. 6 suggests piercing the Ying points (and Shu points according to Unschuld, 2016, but not according to Wu & Wu, 201) of the Yin channels if a disease is in the Yin of the Yin realm (e.g. the Zang organs) suggesting this point (and Taixi Kid-3) in diseases of the Kidney.

    Ling Shu Ch. 9, On Ends and Beginnings, advises that in the case of Heat associated with receding Yin Qi the Yang conduit should be pierced once and the Yin conduits twice. Based on other recommendation to use the He-Sea of the Yang conduits (Ch. 19) and the Yuan-Source with the Ying-Spring points (Chs. 6, 19 and 24) to clear Heat from the Zangfu, that would suggest this point, Taixi Kid-3 and Weizhong Bl-40 as a protocol to clear Heat in the Kidney/Bladder. Next it advises that in Cold associated with receding Yang Qi the Yang should be pierced twice and the Yin> once but no such obvious protocol is evident for this situation.

    Ling Shu Ch. 19, on the Four Seasonal Qi, advises opening the Jing-Well and Ying-Spring openings in winter, piercing deeply and retaining the needle for a while.

    Ling Shu Ch. 22, On Mania and Madness, advises that when Wind invasion and counterflow causes the limbs to become swollen, profuse sweating, a feeling cold and to be irritated when hungry, then blood is removed from the outer and inner sections of the hand Taiyin and foot Shaoyin and Yangming. If the flesh is cool then it is be done through the Ying-Spring points and if the bones are cold it is to be done through the Jing-Well and Jing-River points.

    Ling Shu Ch. 24, On Counterflow Diseases, employs the point combination mentioned in Ch. 6 for the treatment of Heart pain. It advises piercing this point and Taixi Kid-3 when treating a severe piercing pain in the Heart associated with the Spleen. It also advises this point in cases of a Heart pain that feels like being struck, with a bent and painful back, associated with the Kidneys. In this case it is an addition to Jinggu Bl-64 and Kunlun Bl-60 if the patient either becomes mad or if the first two points do not relieve the pain.

    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the Ying-Spring points should be pierced in spring or when the disease is associated with a change in complexion. The seasonal aspect should not be interpreted literally as it describes the colours as "controlled by spring". It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year with morning corresponding to spring.
