督脉始于长强者，本自『灵枢·经脉篇』曰：督脉之别名长强，侠膂上项，
散头上下，当肩胛左右，别走太阳，入贯膂。
注：[1]督脉之别，起于长强者，即绕篡后，外合太阳，循行尾闾间，
长强穴也。
[2]侠膂上项，散头上，下当肩左右，别走太阳，入贯膂，
谓督脉循外而上行也。
[3]故『难经』曰：起于下极之俞。
[4]即长强尾闾间也。
[5]并于脊里，即侠脊也。
[6]上至风府，入属于脑，即上项散头也。
[7]从长强贯脊上行二十一椎下，腰俞穴也。
[8]十六椎下，阳关穴也。
[9]十四椎下，命门穴也。
[10]十三椎下，悬枢穴也。
[11]十一椎下，脊中穴也。
[12]十椎下，中枢穴也。

[20]上至上发际，□门穴也。
[21]从□门入发际，风府穴也。
[22]从风府上行一寸五分枕骨上，脑户穴也。
[23]从脑户上行一寸五分，强间穴也。
[24]从强间上行一寸五分，后顶穴也。
[25]从强间上行一寸五分，后顶穴也。
[26]从后顶上行一寸五分，直两耳尖顶陷中，百会穴也。
[27]从百会前行一寸五分，前顶穴也。
[28]从前顶穴前行一寸五分，□会穴也。
[29]从□会又前行一寸，上星穴也。
[30]从上星至前发际，神庭穴也。
[31]前后发际，合骨度共一尺二寸也，从前发际下至鼻端准头，
素窌穴也。
[32]鼻柱下沟中央近鼻孔陷中，水沟穴也。
[33]唇上端，兑端穴也。

七十七）。
按：『难经』二十八难曰：督脉者，起于下极之俞，并于脊里之上，
至风府入属脑。乃指穴而言也。前论脉起于少腹者，是指循行而言也。

The Du Mai (Du Meridian, Governor Vessel) runs along the midline of the spine. It has twenty-eight acupoints, starting from Changqiang (GV1). Next are Yaoshu (GV12), Yangguan (GV13), entering Mingmen (GV4), followed by Xianshu (GV15), Jizhong (GV9), and Zhongshu (GV12).
Jinsuo (GV8), Zhiyang (GV9) belong to Lingtai (GV10); Shendao (GV11), Shenzhu (GV12), and Taodao (GV13) follow in sequence. Dazhui (GV14), Ximen (GV22) connects to Fengfu (GV16); Naohu (GV17), Qiangjian (GV18), and Houding (GV19) are arranged in order.
Baihui (GV20), Qianding (GV21) connect to Xinhui (GV22); Shangxing (GV23), Shenting (GV24), and Suliao (GV25) correspond oppositely. Shuigou (GV26) and Duanduan (GV27) are located above the lips; Yinjiao (GV28) is inside the upper gum line.

The end of the coccyx is Changqiang (GV1); at the twenty-first vertebra corresponds to Yaoshu (GV12). At the sixteenth vertebra is Yangguan (GV13); at the fourteenth vertebra is Mingmen (GV4); at the thirteenth vertebra is Xianshu (GV15), located in the center of the spine.
At the tenth vertebra is Zhongshu (GV12); at the ninth vertebra is Jinsuo (GV8); below the seventh vertebra is Zhiyang (GV9); at the sixth vertebra is Lingtai (GV10); at the fifth vertebra is Shendao (GV11); at the third vertebra is Shenzhu (GV12); below the first vertebra is Taodao (GV13).
Above the first vertebra is Dazhui (GV14); going up to the hairline is Ximen (GV22). Fengfu (GV16) is taken in the depression, one cun away. Naohu (GV17) is two cun five fen above the occipital bone.
Going up another four cun is the position of Qiangjian (GV18); five cun five fen is Houding (GV19); seven cun is Baihui (GV20), taken at the center of the vertex, which is the central point between the posterior hairlines of both ears.
Moving forward eight cun half is Qianding (GV21); moving forward one chi measures Xinhui (GV22). One chi one cun is the position of Shangxing (GV23); one chi two cun from the anterior hairline is Shenting (GV24).
At the tip of the nose (Zhuntou) is Suliao (GV25); Shuigou (GV26) is hidden in the groove below the nose (Renzhong). Duanduan (GV27) is taken at the upper end of the lip; Yinjiao (GV28) is in the corner of the mouth inside the dental seam.
Commentary:
The Du Mai (Du Meridian, Governor Vessel) starts at Changqiang (GV1). This originally comes from *Lingshu · Jingmai Chapter* stating: The collateral branch of the Du Mai (Du Meridian, Governor Vessel) named Changqiang (GV1) runs alongside the erector spinae muscles up to the neck, scatters around the head above and below, lies opposite the left and right shoulder blades, diverges to run with the Taiyang (Bladder) Meridian, and enters to penetrate the erector spinae muscles.
Notes: [1] The collateral branch of the Du Mai (Du Meridian, Governor Vessel) originates at Changqiang (GV1), i.e., it surrounds the anus posteriorly, externally combines with the Taiyang (Bladder) Meridian, and circulates through the Weili area; this point is Changqiang (GV1).
[2] "Running alongside the erector spinae muscles up to the neck, scattering around the head, lying opposite the left and right shoulder blades, diverging to run with the Taiyang (Bladder) Meridian, and entering to penetrate the erector spinae muscles" refers to the Du Mai (Du Meridian, Governor Vessel) ascending along the lateral side.
[3] Therefore, *Nan Jing* states: Originating from the Shu point of the lower extreme.
[4] That is, the area between the tailbone where Changqiang (GV1) is located.
[5] "Combining into the spine interior," i.e., flanking the spine.
[6] "Ascending to Fengfu (GV16) and entering to belong to the brain," i.e., ascending to the neck and scattering around the head.
[7] From Changqiang (GV1) penetrating up the spine to below the twenty-first vertebra, this is Yaoshu (GV12).
[8] Below the sixteenth vertebra is Yangguan (GV13).
[9] Below the fourteenth vertebra is Mingmen (GV4).
[10] Below the thirteenth vertebra is Xianshu (GV15).
[11] Below the eleventh vertebra is Jizhong (GV9).
[12] Below the tenth vertebra is Zhongshu (GV12).
[13] Below the ninth vertebra is Jinsuo (GV8).
[14] Below the seventh vertebra is Zhiyang (GV9).
[15] Below the sixth vertebra is Lingtai (GV10).
[16] Below the fifth vertebra is Shendao (GV11).
[17] Below the third vertebra is Shenzhu (GV12).
[18] Below the first vertebra is Taodao (GV13).
[19] Above the first vertebra is Dazhui (GV14).
[20] Ascending to the upper hairline is Ximen (GV22).
[21] Entering the hairline from Ximen (GV22) is Fengfu (GV16).
[22] Ascending one cun five fen from Fengfu (GV16) on the upper occipital bone is Naohu (GV17).
[23] Ascending one cun five fen from Naohu (GV17) is Qiangjian (GV18).
[24] Ascending one cun five fen from Qiangjian (GV18) is Houding (GV19).
[25] Ascending one cun five fen from Qiangjian (GV18) is Houding (GV19). (Note: Original text repeats or contains an error here; typically Baihui follows Houding, but translated as per original).
[26] Ascending one cun five fen from Houding (GV19), directly in the depression at the top of the head aligned with the tips of both ears, is Baihui (GV20).
[27] Moving forward one cun five fen from Baihui (GV20) is Qianding (GV21).
[28] Moving forward one cun five fen from Qianding (GV21) is Xinhui (GV22).
[29] Moving forward one cun further from Xinhui (GV22) is Shangxing (GV23).
[30] From Shangxing (GV23) to the anterior hairline is Shenting (GV24).
[31] The distance between the anterior and posterior hairlines measured by bone proportion is one chi two cun. From the anterior hairline down to the tip of the nose (Zhuntou) is Suliao (GV25).
[32] In the central groove below the nasal column, near the nostrils' depression, is Shuigou (GV26).
[33] At the upper end of the lip is Duanduan (GV27).
[34] In the gum seam above the teeth inside the lip is Yinjiao (GV28). These twenty-eight acupoints all circulate along the midline of the back (see Figure 77).
Commentary: *Nan Jing* Twenty-Eighth Difficulty states: The Du Mai (Du Meridian, Governor Vessel) originates from the Shu point of the lower extreme, runs parallel inside the spine upwards, and enters to belong to the brain at Fengfu (GV16). This refers to the acupoints. The previous discussion regarding the meridian originating from the lower abdomen refers to the circulation pathway.
