    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. 23, On Heat Diseases, recommends using this point in cases of Heat disease when the patient pants and coughs. If it is Cold Qi then the needle is retained, if it is Heat Qi it is removed quickly.

    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the Jing-Well points should be pierced in winter or when the disease is in the Zang organs. The seasonal aspect should not be interpreted literally as it describes the nature of winter as the the time of storage and the Zang as "controlled by winter" (i.e. to be storage depots by nature). It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year with night corresponding to winter.


    Ghost Points:
    The first trinity of ghost points, consisting of this point, Shaoshang Lu-11 and Renzhong Du-26, represent the initial stages of being taken over. Being at the peripheries of the body they are aimed at expelling the influence before it takes hold.

    Its Ghost Point name, Guilei, Ghost Fortress, indicates that at this stage is when depression and withdrawal begins to settle in as the ghost erects a barrier to the outside world. Its other name Guiyan, Ghost Eye, reflects this depressive phase in that you now start to see like the ghost.
    Other symptoms may include a heaviness on the chest causing sleepiness but restless dreaming when asleep, known as Guiza, the Ghost sitting on your Chest.

    This is the first of the Ghost Points that is treated with moxa, due to the ghosts Yin nature (Yuen, 2005, 3 Spirits & 7 Souls).
