Xu Chunliang finally chose to insert the needle at the Changqiang point.
Changqiang Point: The endless circulation denotes "Chang," and "Qiang" implies robust motion. This point is located at the end of the spine, marking the starting point of the Governor Vessel. The human spine can freely move and bend from neck to tail, acting as the main load-bearing structure. Its qi moves robustly and endlessly, combined with the abundant and strong yang energy of the Governor Vessel, making this initial point of the Governor Vessel known as Changqiang.
Acupuncture at Changqiang Point mainly treats: hemorrhoids, rectal bleeding, diarrhea, difficulty in urination and defecation, genital damp itch, coccyx pain, epilepsy, hysteria, and lumbosacral neuralgia.
Surrounding the Changqiang Point are four pathways: the Governor Vessel, the Luo Vessel of the Governor Vessel, the Conception Vessel, and the collateral channels of the Foot-Taiyang Bladder Meridian.
