【按】任、督、冲三脉，《素问·骨空论》曰∶任脉起于中极之下，毛际以上。是
外指少腹之分也。循腹里，是内指胞中也。督
脉起于少腹以下骨中央，女子廷孔，男子阴器，合篡贯脊属肾，亦是外指少腹，内指胞
中也。冲脉起于气街，并少阴之经，亦是指于胞中也。虽未明言胞中，而实未尝不起于
胞中也。是以知任、督、冲三脉，皆起于胞中。然三脉皆后天水谷所化，胃气出于气街，
会于胞中，与先天肾间动之真气，并行而充身者也。由此观之，三脉同出一源无疑矣。故
王冰《内经注》、《甲乙经》、《针灸图经》以任脉循背者谓之督脉；自少腹上谓之任脉，亦
谓之督脉，则是以背腹阴阳，别为名目耳。然冲脉亦起于胞中，并足少阴而上行。是任脉、
督脉、冲脉乃一源而三岐者。故人身之有腹背，犹天地之有子午；任督之有前后，犹二
陆之分阴阳也。胞中者，谓男女丹田之通称也。在女子谓之女子胞，在男子即精室也。
冲脉起始于横骨穴，沿肚脐两侧上行，大气（宗气）四处灌注至肓俞穴，经过商曲、石关、阴都、通谷、幽门等穴位，到达胸部后散布并与任脉并行流通。
冲脉的取穴分寸与足少阴肾经相同，从横骨穴起至幽门穴止，向上每两个穴位之间相距一寸，穴位距离正中线左右各五分。
【注】冲脉起始于足阳明胃经的气街部位，并与足少阴肾经在腹部的“气之街”相并而行，位于肚脐正中线的左右两侧各五分处，向上行走。自下腹部耻骨联合上缘的横骨穴开始，依次向上经过大赫、气穴、四满、中注、肓俞、商曲、石关、阴都、通谷、幽门等共十一个穴位，每个穴位向上间距为一寸，穴位偏离正中线左右各五分。
【按语】任脉、督脉、冲脉这三条经脉，《素问·骨空论》中说：任脉起始于中极穴之下，毛际之上。这是从外部指代少腹的部位。循行于腹里，这是从内部指代胞宫（子宫/精室）。督脉起始于少腹以下的骨骼中央，女子为廷孔（尿道口），男子为阴器，会合于篡部（肛门周围），贯穿脊柱归属于肾，这也是从外部指代少腹，内部指代胞宫。冲脉起始于气街，并足少阴肾经而上行，也是指归于胞宫。虽然文中没有明确说明起始于胞宫，但实际上确实是从胞宫起始的。因此可知，任脉、督脉、冲脉这三条经脉，都起始于胞宫。然而这三条经脉都是由后天水谷精微所化生，胃气出于气街，汇聚于胞宫，与先天肾间动气的真气，并行而充养全身。由此看来，三脉同出一源是毫无疑问的。所以王冰在《内经注》、《甲乙经》、《针灸图经》中，将循行于背部者称为督脉；自少腹向上者称为任脉，也称为督脉，这不过是以背腹的阴阳属性来区别命名罢了。然而冲脉也起始于胞宫，并足少阴肾经而上行。所以任脉、督脉、冲脉乃是同源而分出的三条支流。因此人身有腹背之分，犹如天地有子午之分；任督二脉有前后之别，犹如两仪分阴阳。胞宫，是指男女丹田的通称。在女子称为女子胞，在男子即精室。
The Chong Mai (Penetrating Vessel) originates at Henggu (CV12), runs alongside the navel, and its vast qi (Zong Qi, Pectoral Qi) distributes to Huangshu (KI16). It passes through Shangqu (KI15), Shiguan (KI14), Yindu (KI13), Tonggu (KI12), and Youmen (KI14), reaching the chest where it spreads and flows in parallel with the Ren Mai (Conception Vessel).
The measurement of acupoints on the Chong Mai is identical to that of the Foot-Shaoyin Kidney Meridian. Starting from Henggu (CV12) up to Youmen (KI14), each successive acupoint is spaced one cun apart vertically, and located five fen laterally from the midline.
[Note] The Chong Mai originates from the Qichong area of the Foot-Yangming Stomach Meridian and runs parallel to the Foot-Shaoyin Kidney Meridian at the "Street of Qi" in the abdomen. It is located five fen lateral to the midline of the navel and ascends. Starting from the Henggu (CV12) acupoint at the lower abdomen near the pubic symphysis, it ascends sequentially through Dahe (KI12), Qixue (KI13), Siman (KI14), Zhongzhu (KI15), Huangshu (KI16), Shangqu (KI15), Shiguan (KI14), Yindu (KI13), Tonggu (KI12), and Youmen (KI14), totaling eleven acupoints. Each acupoint is spaced one cun apart vertically, and five fen lateral to the midline.
[Commentary] Regarding the Ren Mai (Conception Vessel), Du Mai (Governor Vessel), and Chong Mai (Penetrating Vessel), the *Suwen: Gu Kong Lun* states: "The Ren Mai originates below Zhongji (CV3) and above the pubic hair line." This externally refers to the hypogastric region. "It follows inside the abdomen," this internally refers to the Baogong (Uterus/Essence Chamber). The Du Mai originates from the central bone below the hypogastric region; in women, it is the Tingkong (urethral opening); in men, it is the Yinqi (genitals). They converge at the Cuanyuan (perianal region), penetrate the spine, and connect to the Kidneys. This also externally refers to the hypogastric region and internally to the Baogong. The Chong Mai originates from the Qichong area and runs with the Foot-Shaoyin Meridian, also referring to the Baogong. Although not explicitly stated as originating from the Baogong, it indeed originates there. Thus, it is known that the Ren, Du, and Chong Mai all originate from the Baogong. However, these three meridians are transformed from postnatal water and grain essence. Stomach Qi emerges from the Qichong area, converges in the Baogong, and runs in parallel with the primordial true Qi moving between the kidneys to nourish the whole body. From this perspective, it is undeniable that the three meridians share a common source. Therefore, Wang Bing in his *Neijing Zhu*, the *Jiayi Jing*, and the *Zhenjiu Tujing* referred to the portion running along the back as the Du Mai; the portion ascending from the lower abdomen as the Ren Mai, also called the Du Mai. This is merely distinguishing names based on the yin-yang attributes of the back and abdomen. However, since the Chong Mai also originates from the Baogong and ascends with the Foot-Shaoyin Meridian, the Ren, Du, and Chong Mai are one source branching into three. Thus, the human body's distinction between front and back is like the heaven and earth's distinction between Zi and Wu (North-South axis); the front-back distinction of the Ren and Du Mai is like the division of Yin and Yang by the Two Solids (Taiji). The Baogong is a general term for the Dantian in both men and women. In women, it is called the Nüzibao (Female Uterus); in men, it is the Jingshi (Essence Chamber).
