The *Gu Du Pian* (Chapter on Bone Measurements) states: The circumference of the chest is four chi and five cun, and the circumference of the waist is four chi and two cun. From the laryngeal prominence (Jie Hou) below to the center of the Que Pen (supraclavicular fossa), the length is four cun. From the Que Pen below to the Shu (here referring to the umbilicus; as the umbilical center is difficult to observe directly, adjacent acupoints are used for reference). From the Shu (likely referring to the xiphisternal junction or a specific bony landmark near Ji Wei) below to the Heng Gu (upper margin of the pubic symphysis), the length is six and a half cun. If this measurement exceeds six and a half cun, the transverse colon will be wide; if it is less, it will be narrow and short. The Heng Gu measures six and a half cun. Between the two nipples, the width is nine and a half cun.
Commentary: HT (This character in the original text appears to be an error or variant; based on context and the subsequent mention of "Ren Mai width is one and a half cun," it likely refers to the midline of the chest/Chest Center, i.e., the Ren Mai pathway.) is located at the depression of the Qi Gu (the junction between the body and the xiphoid process of the sternum). The center of the Que Pen is the Tian Tu acupoint. Tian Shu refers to the umbilical center. Because the umbilical center is hard to see, the side acupoints are mentioned for explanation.

[Image: General Diagram of Chest and Abdomen 2]
Commentary: The distance between the two nipples is nine and a half cun, which is also consistent with the *Jia Yi Jing* (*Systematic Classic of Acupuncture and Moxibustion*). Now, let us try to measure: if the distance between the two nipples is nine and a half cun, then one cun corresponds approximately to the width of one finger. Compared to the proportions in the *Gu Du Pian* where the chest circumference is four chi and five cun, why is the standard from the *Gu Du Pian* not adopted when determining the distance between the nipples? This demonstrates a lack of understanding of the meridian distribution in the thorax excluding the Ren Mai. The width of the Ren Mai in the thorax is one and a half cun, and the meridians on either side are four cun away, aligning vertically with the nipples. Scholars, please reflect on this. The method of horizontally measuring eight cun between the nipples is unknown to have originated from whom. The *Shen Ying Jing* (*Divine Response Classic*) states: Horizontal cun is established as the standard method, yet no one has seen this for a thousand years. How sad! The *Xi Yuan Lu* (*Washing Away Wrongdoings*) records: For men, there are twelve ribs on each side, eight long and four short; for women, there are ten...
The line running down the center of the chest contains seven acupoints from Tian Tu down to Zhong Ting.
Tian Tu (SU WEN / Basic Questions), also known as Yu Hu (JIA YI JING) or Tian Qu (QIAN JIN FANG / Essential Prescriptions Worth a Thousand Gold). Located in the center of the Que Pen (LING SHU / Spiritual Pivot), two cun below the laryngeal prominence, in the central depression. Take this point with the head lowered (JIA YI JING).
Commentary: The character "Yu" is written as "Wu" in the *Bao Jian*, which is an error. The *Su Wen* states: There are two points on the central axis of the throat where the Qi of the Ren Mai emerges. The secondary commentary explains: These refer to the Lian Quan and Tian Tu acupoints. The *Qian Jin Fang*, *Qian Jin Yi Fang* (*Supplement to Prescriptions Worth a Thousand Gold*), and *Wai Tai Mi Yao* (*Essential Essential Formulas of the Outer Cabinet*) state "five cun". The commentary in *Jia Yi Jing* cites the commentary on the *Qi Fu Lun* stating "five cun", but the current text says "four cun". The *Ju Ying*, *Yi Tong*, *Bao Jian*, and Wu Wen Bing all agree. The *Ming Tang* states "five fen". The *Fa Hui*, *Ru Men*, and *Da Cheng* state "one cun". The *Lei Jing* states "three cun". None of these are correct. The secondary commentary and *Ru Men* state "take with low needle insertion"; the character "zi" (word/character) is an error. The *Gu Du Pian* states: From the laryngeal prominence to Tian Tu is four cun; this is based on bone measurements. When taking the point on the front of the body in an upright posture. The *Jia Yi Jing* considers: From below the laryngeal prominence to Tian Tu is two cun; this is based on the method of locating the point for needling. Hence it says: "Take with the head lowered." To locate this acupoint, one must lower the head. Therefore, the *Zi Sheng Jing* states: When inserting the needle, direct it horizontally downwards; do not let your hand go too low. Why? Because lowering the hand injures the throat. This explains the meaning of "lowering the head." Lowering the head causes the throat to sink, making needle insertion safe. This must be known. People nowadays do not understand the meaning that it is two cun when the head is lowered and four cun when upright, arbitrarily creating two different explanations, which is incorrect. In recent times, many divide the distance from Tian Tu to the Qi Gu into eight cun and four fen. If this were so, then the Zhong Ting acupoint would be at the Qi Gu, which cannot be accepted. According to the *Gu Du Pian*, the distance from Tian Tu to the Qi Gu is nine cun. It also states: In the chest bones, there is one point in each intercostal space. Currently, using nine cun, specifically eight cun and four fen, as the position of the Zhong Ting acupoint, with six fen remaining below to the Qi Gu, this is the ancient method.
Xuan Ji (JIA YI JING): One cun below Tian Tu, in the central depression. Take with the head raised (JIA YI JING).
Commentary: The character "Ji" is written as "Ji" (machine) in the *Qian Jin Fang*, which is likely an error. The *Qi Fu Lun* states: In the depressions among the bones of the chest, there is one point each. The secondary commentary explains: These refer to Xuan Ji, Hua Gai, Zi Gong, Dan Zhong, and Zhong Ting, totaling six acupoints. The chest diagram lists the measurements but only gives the general outline. Hence it says "in the depression," referring only to the interspace between bones, same as below. The *Da Cheng* states...
Hua Gai (JIA YI JING): One cun below Xuan Ji, in the depression. Take with the head raised (JIA YI JING).
Commentary: The *Fa Hui* states two cun. The *Ru Men*, *Bao Jian*, *Da Cheng*, and *Jin Jian* state one cun and six fen. All are incorrect. They also do not conform to the bone measurements. The first and second ribs are dense and not sparse. Taking one cun refers to the meaning of taking the interspace between bones.
Zi Gong (JIA YI JING): One cun and six fen below Hua Gai, in the depression. Take with the head raised (JIA YI JING).
Yu Tang (NAN JING / Classic of Difficult Issues), also known as Yu Ying (JIA YI JING): One cun and six fen below Zi Gong, in the depression. Take with the head raised (JIA YI JING).
Dan Zhong (NAN JING), also known as Yuan Er (JIA YI JING), also known as Shang Qi Hai (LEI JING), also known as Yuan Jian (DA QUAN). One cun and six fen below Yu Tang, in the depression. Take with the head raised (JIA YI JING), horizontally aligned with the midpoint between the two nipples (QIAN JIN FANG). Prohibited for needling (QIAN JIN YI FANG).
Commentary: The character "Dan" is written as "HT" in the *Qian Jin Fang*, *Qian Jin Yi Fang*, and *Wai Tai Mi Yao*. It was generally used in ancient texts. The *Da Quan* states: Also known as HT Zhong, do not take here. The *Zi Sheng* and *Lei Jing* write "wo" (lie down). The *Jin Xin Zang Pian* states: For chest bi pain, moxa the HT Zhong for one hundred zhu. The acupoint is one cun above Ji Wei, prohibited for needles. This is incorrect.
Zhong Ting (JIA YI JING): One cun and six fen below Dan Zhong, in the depression. Take with the head raised (JIA YI JING).
Commentary: The *Ming Tang* states one cun below Dan Zhong. The *Ru Men* and *Jin Jian* state one cun above Ji Wei. This results from dividing the distance from Tian Tu to the Qi Gu into eight cun and four fen...
The second row of the chest starts from the Shu Fu acupoint, two cun on either side of the Xuan Ji, descending to the Bu Lang acupoint, totaling twelve acupoints.
Shu Fu (SU WEN), also known as Shu Fu (DA QUAN, BAO JIAN): Below Ju Gu, two cun lateral to the Xuan Ji, in the depression. Take with the head raised (JIA YI JING).
Commentary: In the *Jia Yi Jing*, *Wai Tai Mi Yao*, and *Ming Tang*, "Shu" is written as "Shu" (transport), and the same applies below. The *Zi Sheng*, *Sheng Ji Zong Lu*, *Da Quan*, and *Bao Jian* write "Shu". The *Qian Jin Fang*, *Qian Jin Yi Fang*, *Fa Hui*, and *Ju Ying* write "Shu", which is correct. Shu Fu comes from the *Nei Jing*. "Shu", "Shu", and "Yu" are interchangeable due to phonetic similarity. The *Da Quan* and *Bao Jian* consider them one name; we temporarily follow this. The *Qian Jin Yi Fang* writes "wo" (lie down). The *Wai Tai Mi Yao* writes "yang wo" (supine lie). Here, "Ju Gu" refers to the anterior part of the shoulder/clavicle area, not an acupoint name. The Xuan Ji, according to the secondary commentary, is the Ren Mai, which is incorrect. The *Da Quan* states: Three cun lateral to the Xuan Ji, which is wrong. The *Yi Men Zhai Yao* states: When taking points in the chest region by rib spaces, one should not rigidly adhere to one cun and six fen; this shows an understanding of point location methods.
Shen Cang (JIA YI JING): One cun and six fen below Shu Fu, in the depression. Take with the head raised (JIA YI JING).
Commentary: The character "Er" is written as "Wo" in the *Qian Jin Yi Fang*. The *Wai Tai Mi Yao* writes "Yang Wo". And in the bone interspaces, one point is taken each, same as above. The *Ming Tang* says: One cun, which is incorrect.
Subsequent books provide interpretations that each point is two cun from the midline, which is incorrect. See below for the explanation.
Shen Cang (JIA YI JING): [Note: Text repeats Shen Cang header, likely a formatting error in source, proceeding to next distinct point description based on context].
Ling Xu (JIA YI JING): One cun and six fen below Shen Cang, in the depression. Take with the head raised (JIA YI JING).
Commentary: The *Qian Jin Fang* says: Xu may be written as Qiang. The *Ru Men* writes Xu. The *Ju Ying* and *Yi Tong* state "open one cun from the midline", which is an error.
Shen Feng (JIA YI JING): One cun and six fen below Ling Xu, in the depression. Take with the head raised (JIA YI JING).
Bu Lang (JIA YI JING): One cun and six fen below Shen Feng, in the depression. Take with the head raised (JIA YI JING).
Commentary: The character "Lang" is written as "Lang" in the *Qian Jin Fang*, *Wai Tai Mi Yao*, *Sheng Ji Zong Lu*, and *Zi Sheng Jing*. The *Lei Jing* states: Flanking the Zhong Ting. The *Ru Men* states: Outside the Zhong Ting, which is incorrect. Horizontally aligned with the Zhong Ting, slightly lower by about six fen.
The third row of the chest starts from the Qi Hu acupoint, two cun on either side of the Shu Fu, descending to the Ru Gen acupoint, totaling twelve acupoints.
Qi Hu (JIA YI JING): Below Ju Gu, two cun on either side of the Shu Fu, in the depression. Take with the head raised (JIA YI JING).
Commentary: The *Qi Fu Lun* states: In the chest bones, there is one point each. The *Lei Jing*, *Ju Ying*, *Yi Tong*, Wu Wen Bing, *Jin Jian*, and *Da Cheng* provide interpretations that each point is four cun from the midline; see below for the explanation. The secondary commentary states: Four cun and eight fen above the Ying Chuang. The *Ju Ying*, *Yi Tong*, and Wu Wen Bing omit the word "above". The *Jin Jian* states: One cun below Ju Gu, and both are rigid. The *Bao Jian* states: The *Zi Sheng Jing* says: The six acupoints from Qi Hu to Ru Gen are each four cun from the Ying midline, and spaced one cun and six fen apart. This is not recorded in the current text.
Ku Fang (JIA YI JING): One cun and six fen below Qi Hu, in the depression. Take with the head raised (JIA YI JING).
Commentary: Okamoto writes one cun, which is incorrect. When taking points among the bones, one need not be rigid. The explanation is seen above.
Wu Yi (JIA YI JING): One cun and six fen below Ku Fang (JIA YI JING), in the depression. Take with the head raised (QIAN JIN FANG).
Commentary: The secondary commentary states: Three cun and two fen below Qi Hu. The *Ju Ying* states: Four cun and eight fen below Ju Gu. Those who separate the points and discuss their measurements cannot avoid errors.
Ying Chuang (JIA YI JING): One cun and six fen below Wu Yi (JIA YI JING), in the depression (SHENG JI ZONG LU).
Commentary: The *Zi Sheng Jing* writes "Chuang" as "Chuang", which is the same character. The secondary commentary states: On both sides of the chest, flanking the midline, each four cun apart, four cun and eight fen below Ju Gu, which is an error.
Ru Zhong (JIA YI JING): At the nipple (ZI SHENG), i.e., on the nipple tip (RU MEN). Prohibited for needling and moxibustion (JIA YI JING). Light needling (ZI SHENG, also BAO JIAN, citing RU MEN: Needle should be shallow, insert two fen; not seen in current text).
Commentary: The *Jia Yi Jing*, *Qian Jin Fang*, *Qian Jin Yi Fang*, and *Wai Tai Mi Yao* have no commentary. This is the subtlety of ancient texts. The secondary commentary states: Below the Ying Chuang is the Ru Zhong. The *Zi Sheng Jing* commentary says: Also spaced one cun and six fen apart. The phrase "spaced apart" does not make sense here. The *Lei Jing* states: In one transmission regarding retained placenta, moxa the end below the nipple until it falls off.
Ru Gen (JIA YI JING), also known as Xi Xi (QIAN JIN FANG): One cun and six fen below the nipple, in the depression. Take with the head raised (JIA YI JING). Below the nipple, in the depression of the first intercostal space (QIAN JIN FANG).
Commentary: The *Qian Jin Fang* states: Xi Xi is indeed in the depression of the first intercostal space below the nipple. Now moved to the alias section. The *Bao Jian* writes one cun and four fen, which is incorrect. The *Yi Xue Zheng Chuan* states: For women, in the depression where flesh rises below the breast; only the two characters "depression" are applicable for taking the point.
The fourth row of the chest starts from the Yun Men acupoint, two cun on either side of the Qi Hu, descending to the Shi Dou acupoint, totaling twelve acupoints.
Yun Men (SU WEN): Below Ju Gu, two cun on either side of the Qi Hu, in the depression where the artery can be felt. Take with the arm raised (JIA YI JING). Inserting too deeply causes reverse breathing (JIA YI JING). Prohibited for needling (RU MEN).
Commentary: The *Qi Xue Lun* states: Twelve acupoints of the Ying Shu. The secondary commentary states: Referring to Yun Men, Zhong Fu, Zhou Rong, Xiong Xiang, Tian Xi, and Shi Dou; left and right together make twelve acupoints. The *Zi Sheng Jing* writes "Yun" as "Yun", which is generally used. The secondary commentary provides an interpretation that each point is six cun horizontally from the Ren Mai. The *Lei Jing* and *Ju Ying* follow this; see below for the explanation.
Zhong Fu (MAI JING / Pulse Classic), also known as Ying Zhong Shu (JIA YI JING), also known as Fei Mu (QIAN JIN FANG), also known as Fu Zhong Shu (DA QUAN). One cun below Yun Men, in the depression of the third intercostal space above the nipple where the artery can be felt. Take with the head raised (JIA YI JING). Prohibited for moxibustion (RU MEN).
Commentary: For all acupoints in the chest region, since they are located in the bone interspaces, no precise measurement is needed; when measurements are given, they refer to the general outline. The *Qian Jin Fang* and *Wai Tai Mi Yao* state: One cun and six fen. The *Ming Tang*, *Da Cheng*, and Okamoto follow this, which is incorrect. The sternum is shaped like a recumbent moon; therefore, the measurement in the second row is slightly longer, while the third row is level with the midline. Scholars should observe this. "Ying Zhong Shu" is written as "Ying Shu" in the *Ju Ying* and *Yi Tong*. The *Su Wen* states: Ying Shu. The secondary commentary states: The Zhong Fu acupoint.
Zhou Rong (JIA YI JING): One cun and six fen below Zhong Fu, in the depression. Take with the head raised (JIA YI JING). Prohibited for moxibustion (RU MEN, BAO JIAN).
Commentary: The character "Rong" is written as "Ying" in the *Jia Yi Jing*, which is an error. Corrected now.
Xiong Xiang (JIA YI JING): One cun and six fen below Zhou Rong, in the depression. Take with the head raised (JIA YI JING).
Tian Xi (JIA YI JING): One cun and six fen below Xiong Xiang, in the depression. Take with the head raised (JIA YI JING).
Shi Dou (JIA YI JING): One cun and six fen below Tian Xi, in the depression. Take with the head raised (JIA YI JING). Take with the arm raised (QIAN JIN FANG).
Commentary: The *Jin Jian* states: Ascend three cun from Fu Ai, or descend six cun and four fen from the third intercostal space above the nipple where the artery can be felt. This is overly circuitous. The secondary commentary states: Yun Men and Shi Dou are taken with the arm raised; the rest are taken with the head raised.
