春夏季节进行针刺时，都应先深刺而后浅刺。秋冬季节进行针刺时，都应先浅刺而后深刺。凡是补法或泻法，都是如此。
凡是补法和泻法的操作，都像前面所述那样。如果病人患有热证，当感觉到针气到达病所时，立即将针退出二三分，让病人用口吸气，用鼻呼气。根据本经的生成数（指五行生成数理，此处指行针次数或时间）补足后，感觉到针下有阴气隆盛到来，便按照前面的方法出针。如果病人患有寒证，当感觉到针气到达病所时，立即将针推进二三分，让病人用鼻吸气，用口呼气。根据本经的生成数补足后，感觉到针下阳气隆盛到来，便按照前面的方法出针。
《黄帝针经》说：邪气盛则用泻法，正气虚则用补法。用火补法时，不要吹火，必须等待艾火自然熄灭。用火泻法时，要快速吹火，促使艾火尽快熄灭。
丁德用注释《难经》说：升、斗、秤、尺这四种度量衡器具，首先要校正“尺”，然后才能制造升、斗、秤和两。都使用“同身寸”作为标准。以尺来造斗，面阔一尺，庭宽七寸，高四寸，后面再减去三分，刚好能容纳十升。凡是利用木材纹理脉络完整的木块，一方寸为一两，十六方寸为一斤。这是制作同身寸、尺、升、斗的尺度，是依据人的肠胃轻重长短的比例制定的。洁古老人（张元素）说：丁公的注释是正确的。
《黄帝明堂灸经》引用《岐伯明堂经》的话说：以八寸为尺，以五分为一寸。因为人有高矮胖瘦的不同，取穴不准确。秦代扁鹊《明堂经》说：取男子左手、女子右手的中间手指第一节长度为一寸。但因为有人身体长手短、或身体短手长，导致取穴不准确。唐代孙思邈《明堂经》说：取病患男子左手、女子右手的大拇指关节横纹宽度为一寸。这需要用心斟酌，巧拙在于人，也会有误差。现在取男子左手、女子右手中指第二节内侧，两个横纹之间的距离为一寸。自从采用这种取寸法给人施灸治病以来，大多获得痊愈。这种方法有准绳，现在已定为标准了。《素问要旨论》说：取灸法中的寸法，从男子左手、女子右手的中指与大拇指相接成环无端的状态测量，量取中指上侧两个横纹之间的距离为一寸。
When performing acupuncture in spring and summer, one should first insert the needle deeply and then shallowly. When performing acupuncture in autumn and winter, one should first insert the needle shallowly and then deeply. This applies to both tonification (Bu, 补) and sedation (Xie, 泻) techniques.
The methods for tonification and sedation are as described above. If the patient suffers from a heat syndrome (Re Zheng, 热证), upon sensing that the needle Qi (Zhen Qi, 针气) has reached the affected area, withdraw the needle by two or three fen (fen, 分). Instruct the patient to inhale through the mouth and exhale through the nose. After completing the requisite number of manipulations based on the generating numbers of the meridian (Ben Jing Sheng Cheng Shu, 本经生成数), when a sensation of abundant Yin Qi (Yin Qi, 阴气) is felt under the needle, remove the needle according to the previously stated method. If the patient suffers from a cold syndrome (Han Zheng, 寒证), upon sensing that the needle Qi has reached the affected area, advance the needle by two or three fen. Instruct the patient to inhale through the nose and exhale through the mouth. After completing the requisite number of manipulations based on the generating numbers of the meridian, when a sensation of abundant Yang Qi (Yang Qi, 阳气) is felt under the needle, remove the needle according to the previously stated method.
The *Huangdi Zhenjing* (Yellow Emperor's Classic of Acupuncture) states: "If Qi is excessive, use sedation; if Qi is deficient, use tonification." For fire tonification, do not blow on the moxa; wait for it to extinguish naturally. For fire sedation, blow rapidly on the moxa to hasten its extinction.
Ding Deyong, in his commentary on the *Nan Jing* (Classic of Difficult Issues), states: Regarding the four measuring instruments—the sheng (sheng, 升), dou (dou, 斗), cheng (cheng, 秤), and chi (chi, 尺)—one must first calibrate the chi. Then, the sheng, dou, cheng, and liang (liang, 两) can be manufactured. All measurements utilize the Tong Shen Cun (Tongshenchun, 同身寸 - body-inch). To construct a dou using the chi: the width at the top is one chi, the width at the bottom is seven cun, the height is four cun, and subtracting three fen from the rear allows it to hold exactly ten sheng. For wooden blocks with complete grain patterns, one square cun equals one liang, and sixteen square cun equal one jin (jin, 斤). This system of creating Tong Shen Cun, chi, sheng, and dou serves as a standard for the weight, lightness, length, and shortness of human intestines and stomachs. Jiegou Laoren (Zhang Yuansu, 张元素) stated: "Master Ding's commentary is correct."
The *Huangdi Mingtang Jiujing* (Yellow Emperor's Bright Hall Moxibustion Classic) cites the *Qibo Mingtang Jing*: "Use eight cun as one chi, and five fen as one cun." However, due to variations in people's height and build, acupoint selection may be inaccurate. Bian Que's *Mingtang Jing* from the Qin Dynasty stated: "For men, use the left hand; for women, use the right hand. The first segment of the middle finger constitutes one cun." Yet, because some individuals have long bodies with short hands, or short bodies with long hands, acupoint selection remains inaccurate. Sun Simiao's *Mingtang Jing* from the Tang Dynasty stated: "For patients, take the man's left hand or woman's right hand. The transverse crease of the thumb joint constitutes one cun." This requires careful deliberation; accuracy depends on the practitioner, and errors may occur. Currently, we take the distance between the two transverse creases on the inner side of the second segment of the middle finger of the man's left hand or woman's right hand as one cun. Since adopting this method of measuring cun for moxibustion treatment, most patients have recovered. This method provides precision and is now established as the standard. The *Suwen Yaozhi Lun* (Essential Principles of the Plain Questions) states: "For the moxibustion measurement method, join the middle finger and thumb of the man's left hand or woman's right hand into a ring without beginning or end. Measure the distance between the two transverse creases on the dorsal side of the middle finger as one cun."
