The *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) states: People vary in age (young and old), body length (tall and short), and physique (fat and thin). One must carefully ponder and measure, using accuracy as the standard for determination. Furthermore, one should consider the muscle fibers, joint fissures, tendon intersections, and depressions. By pressing with the hand, if the patient feels relief or comfort (indicating the pathogen is being addressed), such meticulous and serene attention allows one to locate the acupoint. It also states: Some individuals are short in stature but long in arms; some are tall but short in arms; some have long chests and abdomens, others short; some large, some small. These cannot be generalized. When marking an acupoint, moxibustion should be applied immediately after marking. If this sequence is reversed or the position shifts, the true acupoint will not be found. In general, moxibustion should follow the order of Yang meridians before Yin meridians, upper body before lower body, and fewer applications before more applications; all these should be examined prudently.

The Yellow Emperor said: If the moxa cone does not reach a thickness of three fen, it is considered a futile suffering for the patient; the moxa cone should be made large. For those with weak constitutions, it should be made smaller. For infants older than seven days but under one year old, the moxa cones should be large, except on the head and four limbs, where they should be small, solely to dispel wind pathogens.

The *Qianjin Fang* states: Regarding the number of "zhuang" (moxa cones/cones burned): If the patient is robust and the disease root is deep and severe, the number can be doubled compared to the standard prescription. For the elderly and the emaciated/weak, the number can be halved. Bian Que’s moxibustion method involves inserting the needle six fen deep and burning three zhuang, with no further discussion. Therefore, later generations did not adhere to fixed standards but increased or decreased the dosage based on the severity of the illness. For moxibustion on the top of the head, up to seven zhuang are used, accumulating to forty-nine zhuang (7 x 7). The *Tongren* (Illustrated Manual of Acupoints and Meridians) states that for treating wind diseases, points Shangxing (GV23), Qding (GV21), and Baihui (GV20) are moxibusted up to two hundred zhuang. The abdomen and back are suitable for five hundred zhuang. However, for Jiwei (CV15) and Jueque (CV14), excessive moxibustion should be avoided, as too much may cause the four limbs to become thin and weak. It is also stated that for Zusanli (ST36), the number can reach two to three hundred zhuang. Xinshu (BL15) is contraindicated for moxibustion; however, in cases of stroke, emergency moxibustion up to one hundred zhuang is applied. All depend on the severity of the illness. One must not rigidly adhere to one saying while ignoring another. The *Xia Jing* (Lower Classic) only states that for contraindicated points, the *Mingtang* (Hall of Brightness) permits one to three zhuang, which may be incomplete. How can hundreds or thousands of zhuang be completed in one day? It requires waiting three, five, or seven days, or even three to five years, to exhaust the total number.
