《黄帝内经·素问·诊要经终论》
秋天刺了冬天的部位，伤了肾气，病不能愈，使人肾不闭藏，血气内散，时时发冷。
秋刺冬分，病不已，令人洒洒时寒。
If you pierce the winter position in autumn, the qi of the kidney will be damaged, the disease will not be cured, the kidneys will not be closed, the qi and blood will be dispersed, and the person will feel cold from time to time.
