    Ling Shu Ch. 10, On Channels, describes the diseases relating to the Luo emanating from this point as:
    Repletion: Pain in the heart
    Depletion: The head feels heavy
    (Unschuld, 2016).

    Ling Shu Ch. 19, On the Four Seasonal Qi, advises using the channels and Luo vessels for diseases which occur in spring. They are pierced deeply if severe and more shallow if mild. For the other seasons:
    - in summer choose the Yang channels and Luo located in the partings between the skin and flesh
    - in autumn choose the Shu-Stream points unless the disease in the Fu organs, then use the He-Sea points
    - in winter choose Jing-Well and Ying-Spring opening and retain the needle.

    Ling Shu Ch. 21, On Cold and Heat Diseases, repeats the advice to use Luo in spring but and adds that they can also treat diseases of the skin. For the other seasons it differs slightly from Ch. 19:
    - in summer choose the partings in skin structures which also treat the muscle and flesh
    - in autumn Taiyuan Lu-9 is chosen and can treat the sinews and vessels (this may also apply to other Shu-Stream points for this purpose, text is unclear)
    - in winter one chooses the main channel points which also treat the bones and marrow.

    Ling Shu Ch. 52, On the Wei Qi, considers this to be the root of the hand Jueyin meridian with the tip being at Tianchi Pc-1.
