The *Qianjin Fang* states: People vary in age, from young to old; their bodies differ in height, tall or short; and their skin varies in condition, fat or thin. One must carefully ponder and discuss these factors, measuring and adjusting accordingly. Furthermore, one should rely on the muscle textures, joint fissures, depressions where acupoints are located, and areas that feel distinctly painful upon manual pressure. Only by operating with such meticulousness, calmness, and dedication can one master this art. Xu Xi also stated: Some individuals have a short stature but long arms, while others have short arms but a tall body; some have short chests and abdomens, others long ones; some are emaciated, others obese. These conditions cannot be generalized uniformly. It is further stated that moxibustion should follow the principle of treating Yang meridians before Yin meridians. This means starting from the head, moving gradually downward to the left, and then from the head, moving gradually downward to the right; generally treating upper parts before lower parts.

The hand meridians contain the Sanli (Three Li) and Wuli (Five Li) acupoints, and the foot meridians also have Sanli and Wuli points. The hand meridians have Shanglian (Upper Margin) and Xialian (Lower Margin) acupoints, and the foot meridians similarly possess Shanglian and Xialian points. On the lateral side of the head, there is the Qiaoyin (Aperture of Yin) acupoint, and the Foot-Shaoyang Gallbladder Meridian also has a Qiaoyin point. In prone positions, there is the Linqi (Approaching Tears) acupoint, and the Foot-Shaoyang Gallbladder Meridian also has a Linqi point. Since there is already a Wuli point, Laogong (Palace of Toil) is also named Wuli. Since there is already a Guangming (Bright Light) point, Cuanzhu (Gathering Bamboo) is also named Guangming. There is Jianjing (Shoulder Well) on the shoulder, and there is also what is called Zhongjianjing (Middle Shoulder Well). There is Kunlun (Kunlun Pass) on the foot, and there is also what is called Xia Kunlun (Lower Kunlun). The names Taiyuan (Great Abyss) and Taiquan (Great Spring) may differ slightly; the characters Tianding (Heavenly Tripod) and Tiding (Heavenly Summit) may vary. Dantian (Elixir Field) was originally not Shimen (Stone Gate); Heliao (Grain Hole) is not He Liao (Harmony Hole). Yangqiao (Yang Heel Vessel) is actually Shenmai (Shen Pulse), not Fuyang (Nourishing Yang). Yinqiao (Yin Heel Vessel) is actually Zhaohai (Illuminating Sea), not Jiaoxin (Connecting Heart). The name Jianyu (Shouldle Bone Gap) appears in the *Waitai Miyao* regarding bone structures. The name Xuanzhong (Hanging Middle), Juegu (Broken Bone), Tongzi (Child), and Qian Guan (Front Pass) appear in the annotations of the *Qianjin Fang*. There are many such cases. How can one perform acupuncture and moxibustion without careful deliberation? If one does not deliberate carefully, a difference of a hair's breadth will result in an error of many feet. Therefore, I list these essentials to show to physicians of the world, urging them to be cautious regarding moxa points.

Aged mugwort (Chen Ai) is suitable for moxibustion. Regardless of quantity, select the leaves, place them in a mortar, and gently pound with a wooden pestle until warm. Sift through a fine sieve to remove green dregs. Pound again and sift again. Repeat this three times. Then pass it through a horsehair sieve, pounding and sifting once more. Continue until the mugwort becomes soft, fine, yellow, and warm.

The *Qianjin Fang* states: Huangdi said, "If moxibustion does not reach a depth of three fen, it is considered a wrongful suffering [for the patient]. The moxa cone must be large; if the patient is weak, make it smaller." (It is also stated: For infants older than seven days up to one year, do not exceed seven cones, and the cone size should be like a sparrow's droppings.) The *Mingtang Xia Jing* states: "In all moxibustion, the base of the moxa cone should be wide to three fen. If it is less than three fen, the fire qi cannot reach deeply, and the disease will not heal." Thus, moxa cones should generally be large, except for the head and four limbs, where they should be small. However, the *Mingtang Shang Jing* states that moxa cones should be made according to the size of a bamboo fiber tip. For conditions where the pulse is thin and thread-like, as long as the moxa is applied directly to the meridian, even cones the size of sparrow droppings can cure the disease. In another category, such as abdominal hernias, masses, fixed lumps, or Fu-Liang Qi, large moxa cones are required. Thus, the *Duan Ju* states: "Burning the abdomen and back until the limbs are affected merely expels wind pathogenic factors." For acupoints such as Jueque and Jiutui, although located on the chest and abdomen, moxibustion should not exceed 4x7 (28) cones. The cone size should only be that of a bamboo fiber tip. As long as the moxa is applied correctly to the meridian, if the cones are too large and the number of applications excessive, the person will permanently lose heart energy. Excessive moxibustion on the head causes loss of spirit. Excessive moxibustion on the arms and legs causes depletion of blood vessels, resulting in thin and weak limbs. Losing spirit combined with physical emaciation leads to a short lifespan. This discussion is very appropriate, so it is recorded in detail.
