再次使用前面测量的同身寸纸蔑。从脊柱正中第五胸椎上缘中央，即墨线所圈之处，沿着脊骨端点垂直向下比量四寸。
到达第七胸椎处，用墨点做标记。从该墨点向两侧向上斜着测量至灸穴圆圈的中心，使每侧恰好为同身寸的五寸，以此作为左右两穴高低平直的基准。
让患者身体平正端正地坐着。用自己的右手搭在右肩上按住颈部，手指伸直平搭在背上，用墨记中指指尖所触及的地方。
左手也这样记录。然后再从肩胛骨的上角摸索到肩胛骨的下端，这中间应当有四根肋骨、三个间隙（这四根肋骨是从肩胛骨横向排列至脊骨上方，用力按摩时，如果感觉是指腹陷入而非骨头，那是筋而不是骨，《千金方》说“筋间空处”，怀疑“四肋”的“肋”字是误写，而王惟一在《铜人腧穴针灸图经》中，又将“筋间”改为“肋间”。以及用右手搭在右肩上按住颈部的方法也一样。《千金翼方》改为搭在左肩上。如果用右手搭在左肩上，那么手指触及的地方已经在第五胸椎下方，距离穴位很远，都不对。应当以《千金方》为准）。灸穴应当在三个间隙的中间，依据肩胛骨下缘，容纳侧放一指宽度的地方，触摸肌肉表面，在筋间空处的穴位上按压，自觉有牵引感通向胸部和肩部（《千金翼方》说牵引肩部。石藏用又用篦子或发簪头按压穴位，使其坚实，让患者容易感知）。并对照之前圈出的灸穴，位于先前记录的患手手指触及处的下方，或者旁边手指不可及的地方，以此来验证穴位的正确与否。然而手指有长短，皮肤有胖瘦，如果相合固然好，如果不相合，就不能因为这一种方法，就废弃其他方法。也有人肩胛骨距离脊骨较远，超过同身寸三寸以上的，这就难以使用脊柱两旁各三寸的方法，只需寻找四根肋骨、三个间隙的中间，依据肩胛骨下缘容纳侧放一指宽度的地方作为穴位即可。
Again, use the paper strip previously measured for *tongshen cun* (body-inch measurement). From the center of the upper border of the fifth thoracic vertebra (*D5*) on the midline of the spine, where the ink circle is located, measure vertically downward along the end of the spinal column four *cun*.
Arrive at the seventh thoracic vertebra (*D7*), and mark with ink. From this ink mark, measure obliquely upward to both sides to the center of the moxibustion acupoint circle, ensuring each side is exactly five *cun*, serving as the standard for the level and straightness of the two acupoints.
Instruct the patient to sit upright with a straight posture. Use their own right hand to rest on the right shoulder, anchoring the neck, extending the fingers flatly onto the back, and mark with ink the spot reached by the tip of the middle finger.
Perform the same recording with the left hand. Then, palpate from the superior angle of the scapula to the inferior end of the scapula; between these points, there should be four ribs and three intercostal spaces (these four ribs extend horizontally from the scapula to the upper part of the spinal column. When massaging with force, if it feels like the finger sinks in rather than hitting bone, it is tendon/muscle, not bone. The *Qianjin Fang* states "empty space among tendons," suspecting that the character "rib" (*lei*) in "four ribs" is an error. Wang Yiyi, in the *Tongren Shuxue Zhenjiu Tujing* (Illustrated Manual of Acupuncture Points of the Bronze Man), further changed "among tendons" to "intercostal." The method of resting the right hand on the right shoulder is the same. The *Qianjin Yifang* changes it to resting on the left shoulder. If the right hand rests on the left shoulder, the finger would reach below the fifth thoracic vertebra, far from the acupoint, which is incorrect. One should follow the *Qianjin Fang* as correct). The moxibustion acupoint should be in the middle of the three intercostal spaces, based on the lower edge of the scapula, allowing space for one finger placed sideways, touching the surface of the muscle. Press on the acupoint in the empty space among the tendons; the patient should feel a pulling sensation radiating to the chest and shoulder (*Qianjin Yifang* mentions pulling to the shoulder. Shi Cangyong also used a comb or the head of a hairpin to press the acupoint firmly so the patient can perceive it easily). Compare this with the previously circled moxibustion acupoint, which should be below the previously marked spot reached by the patient's finger, or to the side where the finger cannot reach, to verify the correctness of the acupoint. However, fingers vary in length, and skin varies in thickness. If they coincide, it is good; if not, do not discard other methods solely based on this single criterion. Some individuals have scapulae far from the spinal column, exceeding three *cun*, making the method of locating acupoints three *cun* lateral to the spine difficult. In such cases, simply find the middle of the four ribs and three intercostal spaces, based on the lower edge of the scapula allowing space for one finger placed sideways, as the acupoint.
