    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 the Yin Qiao Mai along with this point and bleeding the Luo for dysuria from a bulging disease (maybe prostate?).

    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.
