2) Xuanzhu (Xuánzhù, Hanging Pillar). "Xuan" means to hang. "Zhu" means pillar. The name Xuanzhu refers to the Qi and Blood in this acupoint being strong and vigorous Qi at the Heaven level (upper part of the body). The material of this acupoint is the Heaven-level Qi transmitted from Mingmen (Mìngmén, Gate of Life) and Jizhong (Jízhōng, Spine Center). Its Qi is powerful, filling the Du Meridian (Governor Vessel) and the waist and spine regions like a pillar, hence the name Xuanzhu.
Qi and Blood Characteristics: The material is strong Yang Qi at the Heaven level.
Movement Pattern: It circulates along the Heaven level, transmitting up and down the Du Meridian and throughout the waist and spine regions.
Functions and Actions: Strengthens Yang and benefits Qi.
Treatment Method: For Cold patterns, apply tonification and moxibustion; for Heat patterns, apply sedation to release pathogenic Qi.
6 Jizhong (Jízhōng, Spine Center)
Aliases: Shenzong (Shénzōng), Jishu (Jíshū).
Acupoint Meaning: High-temperature, high-pressure fluid from the interior and exterior of the spinal bone rapidly vaporizes here.
Name Explanation: 1) Jizhong. "Ji" refers to the Qi and Blood originating from the spinal bone. "Zhong" contrasts with "outside," referring to the interior of the acupoint. The name Jizhong implies that high-temperature, high-pressure fluid from the spinal bone rapidly vaporizes into Heaven-level Yang Qi upon exiting the body surface. This acupoint is located at the center of the human gravity field on the dorsal body surface. The Qi and Blood within are high-temperature, high-pressure fluids transported internally and externally by the spinal bone; upon exiting the body surface, they rapidly vaporize into Heaven-level Yang Qi, hence the name Jizhong. The meaning of Jishu is identical to Jizhong, where "Shu" is synonymous with "Shu" (transport).
2) Shenzong. "Shen" contrasts with "Gui" (ghosts), referring to Heaven-level Yang Qi. "Zong" means ancestor or source, indicating the origin of Qi, also referring to water. The name Shenzong implies that the Heaven-level Yang Qi within this acupoint is transformed from the high-temperature, high-pressure fluid originating from the spinal bone. The principle is the same as the explanation for Jizhong.
Qi and Blood Characteristics: The material is Heaven-level Yang Qi.
Movement Pattern: After dissipating heat, it transmits along the Du Meridian to Zhongshu (Zhōngshū, Central Pivot) and Xuanshu (Xuánshū, Hanging Pivot).
