The *Neijing* states: "When the pulse of the Hand-Shaoyin channel beats vigorously, it indicates pregnancy." This refers to the pulse at the Shu point of the Hand-Shaoyin channel, specifically the Shenmen acupoint (Shenmen), where a vigorous pulse is a sign of pregnancy, not referring to the "Moving Pulse" (Dong Mai) as a specific pulse condition. The concept of the Moving Pulse originated with Zhang Zhongjing, who stated: "When Yin and Yang contend with each other, it is called 'Moving'." If Yang moves, there is sweating; if Yin moves, there is fever, coldness of the body, and aversion to cold, indicating injury to the Sanjiao (Triple Burner). Cheng Wuji said: "When Yin and Yang contend, the deficient side manifests as a Moving Pulse. Deficiency of Yang leads to Yang movement, hence sweating; deficiency of Yin leads to Yin movement, hence fever. If there is no fever or sweating, but rather coldness of the body and aversion to cold, it signifies injury to the Sanjiao and obstruction of Yang Qi." Pang Anchang said: "The Guan position occupies six fen in length; the anterior three fen are Yang, and the posterior three fen are Yin. If the movement occurs in the Yang region (Cun position), extending to the Cun Kou, while the Yin region (Chi position) remains quiet, according to the principles, the disease should resolve through sweating. The *Suwen* states: 'Yang acting upon Yin is called sweat.' If the movement occurs in the Yin region (Chi position), extending to the Chi, while the Yang region (Cun position) remains quiet, then fever will occur. The *Suwen* states: 'Coarseness of the Chi pulse indicates heat within.' If after profuse sweating, symptoms of body coldness and aversion to cold appear, this is injury to the Sanjiao and constitutes a fatal syndrome. The Moving Pulse is only seen at the Guan position; only Pang's explanation is clear. Cheng Wuji further stated: 'Yang exits and Yin enters, with the Guan serving as the boundary; the Guan is the midpoint of Yin and Yang.' If a Rapid Pulse appears at the Guan, without head or tail, resembling the size of a bean, trembling and moving, this represents the contention of Yin and Yang Qi. 'Jue Jue' describes the independent trembling of the pulse, distinct from the three positions, like a person in a crowd who does not blend with others, thus named 'Jue Jue'. Shen Shi said: 'Yang movement occurs because Yang Qi cannot protect the skin and pores, leading to sweating; Yin movement occurs because Yin Qi cannot nourish the muscles, leading to fever.' This aligns with Zhang Zhongjing’s statement: 'Mild Yang leads to aversion to cold, weak Yin leads to fever,' which refers to this phenomenon.

[Poem on the Moving Pulse] The root lies in Qi governing Yin, / When Yin and Yang contend, the pulse form appears. / At the three Guan positions, fingers feel heavy and deep, / In the Guan center, like a bean, it trembles frequently.
The Moving Pulse is seen at the Guan position, not in the Cun and Chi positions of the three Guan. It manifests as Jue Jue trembling, rather than being heavy and obstructing under the fingers. Chi Shi propagated erroneous interpretations, so I have corrected this.

[Poem on Blood Emission and Retrograde Menstruation] Retrograde menstruation with bleeding for years, / Wise physicians and famous doctors are hard to find. / Pain and fright are recorded in the *Mai Jing*.
The *Neijing* states: "Yin deficiency and Yang contention cause Bing (uterine bleeding)." Insufficiency of Yin pulses and excessive, contending Yang pulses lead to internal collapse, with blood flowing downward. The Moving Pulse causing uterine bleeding corresponds to what Zhang Zhongjing called "Yin movement." Yin deficiency and internal damage manifest as a Moving and Rapid pulse, not Yang contention.

[Nine] The Fine Pulse belongs to Yin. Under the fingers, searching reveals it as fine as a thread. Its coming and going are extremely minute. (Slightly larger than the Micro pulse, yet consistently present and fine.) It is called the Fine Pulse, primarily indicating coldness of the bone marrow in the lower legs and feet, fatigue, and shortness of breath.
The *Mai Jing* states: "The Fine Pulse is Yin." The pulse is straight, fine, and soft, responding to the finger like a silk thread, indicating insufficiency of Blood and decline of Qi. If these symptoms are present, the pulse matches the condition, which is favorable; if the pulse appears without these symptoms, it is unfavorable. Therefore, in cases of hematemesis or epistaxis, the appearance of a Deep and Fine pulse indicates survival. Since blood flows within the vessels, a reduction in blood volume causes the pulse to become fine. Although blood is insufficient, it has not reached the stage of hemorrhage, so the pulse stops at being Fine and does not disappear. If blood is completely lost, the pulse also disappears; thus, the Choppy Pulse (Kou Mai) indicates blood loss. From this, we know that the Choppy Pulse indicates blood loss, while the Fine Pulse indicates blood insufficiency. The current *Mai Jue* states that the Fine Pulse is "extremely minute in its coming and going," which is even more minute than the Micro pulse, and thus is no longer a Fine Pulse. I have corrected this here.

Fatigue, lack of essence, soreness in the shins, / Emaciation, haggard appearance, dry hair. / If encountered in winter, during frosty months, / Without treatment, the illness will surely heal itself.
After winter, when Yang Qi begins to generate, physiological functions may recover. However, one cannot claim that the disease heals spontaneously without treatment. Now, the Scattered Pulse and Rapid Pulse are added to fulfill the original intent of the *Mai Jing*.

The Rapid Pulse belongs to Yang. Six beats per respiration. Alternatively defined as: coming and going rapidly and hurriedly is the Rapid Pulse.
The *Neijing* states: "Rapid indicates Heat." One must examine whether it is Floating or Deep to determine if the heat is in the Exterior or Interior; observe its magnitude to determine the severity of the heat. There are also pulses that resemble the Rapid Pulse. The *Neijing* states: "A pulse arriving like a Rapid pulse causes sudden fright." This requires careful discrimination. Shen Shi said: From the perspective of Yin and Yang, Rapid is a Yang pulse; from the perspective of Zang-Fu organs, Rapid indicates Fu organ disease; regarding pathogenic factors, it indicates Heat; regarding pathology, it indicates Deficiency. For a Micro-Rapid pulse, in cases of Cold Damage (Shanghan), sweating must be strictly avoided; in healthy individuals, overexertion must be strictly avoided. This is an axiom of the sages. The *Neijing* states: "Rapid indicates vexation of the heart." Only in children, where eight beats per respiration are Fine and Rapid, is this considered a normal pulse.

The Scattered Pulse is large and scattered. Qi deficiency and Blood insufficiency, having an Exterior but lacking an Interior, result in a Scattered pulse.
Shen Shi said: Scattered means not gathering. Zhang Zhongjing stated: "In Cold Damage, with coughing, wheezing, and upward rushing of Qi, if the pulse is Scattered, death ensues." If the pulse contains pathogenic factors, it is Wind. The *Nanjing* states: "Floating, large, and Scattered is the Heart pulse." The greatest fear is the solitary appearance of the Scattered pulse; if it appears alone, it is perilous. Liu Shi said: This implies being scattered without order or constraint. Under the fingers, the movement feels irregular; between one or two beats, another beat arrives, never coming and going regularly. Sometimes it moves and immediately vanishes; sometimes many come and few go; sometimes many go and few come. This represents dispersion and failure to gather, with Essence and Blood dissipating and the root becoming detached, which is an inauspicious omen. If seen in a parturient woman, it predicts childbirth; if seen in a pregnant woman, it predicts miscarriage or injury. In ordinary individuals' Heart pulses and during summer months, it is most inadvisable to see this pulse appearing alone.
