    Ling Shu Ch. 6 suggests piercing the Jing points of the Yin channels if a disease is in the Yin of the Yang realm (e.g. the sinews and bones). This would mean using this point to treat disorders of the hip, knee and ankle.

    Ch. 7 then suggests using paired needles either side of the tendon to remove a tendon blockage illness, and straight needling to the bone for bone blockage illness. This could be interpreted as using these technique on this point, on either side of the tibialis anterior in incidences of injury to this tendon or straight in cases of ankle injury, or using them as local techniques while Ch. 6 is a distal point suggestion.

    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the Jing-River points should be pierced in late summer or when the disease affects the voice. The seasonal aspect should not be interpreted literally as it describes the voice and musical notes as "controlled by late summer". It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year although late summer is not included in this comparison but presumably has some correlate (maybe late afternoon).

    Ling Shu Ch. 52, On the Wei Qi, considers this to be the root of the foot Jueyin meridian with the tip being at Ganshu Bl-18.
