The four-character pulse rhyme originated from the True Person Cui Zixu, was revised by Li Binhu, and further revised by Li Shicai. In recent times, various editions such as those in *Feng Shi Jin Nang* (冯氏锦囊) have added or deleted content; however, they are either too verbose and disorganized or too concise and incomplete. Moreover, they are confined to the old theories of Wang Shuhe, Gaoyang Sheng, and Hua Brenren. The more items listed, the more confused the finger perception becomes, making them all inferior texts. I have taken the eight clearly visible pulses as the main framework, using combined pulses as sub-items, rhymed in four characters, so that readers may achieve the subtle skill of handling them with ease.
Floating (Fu Mai, 浮脉) primarily indicates exterior conditions, belongs to the fu organs and yang. A light touch reveals its image clearly: if floating and forceful, it is the Surging Pulse (Hong Mai, 洪脉), indicating fire; if floating and weak, it is the Deficient Pulse (Xu Mai, 虚脉), indicating qi injury; if floating and extremely deficient, it is the Scattered Pulse (San Mai, 散脉), indicating dispersion of qi and blood; if floating like a scallion stalk, it is the Hollow Pulse (Kou Mai, 芤脉), indicating blood loss; if floating like pressing on a drum, it is the Wiry-Empty Pulse (Ge Mai, 革脉), which is externally strong but internally hollow (more severe than Kou, indicating failure of yin-yang interaction); if floating, soft, and fine, it is the Soggy Pulse (Ru Mai, 濡脉), indicating dampness obstruction. When Floating combines with six other pulses, similarities must be examined in detail.
Deep (Chen Mai, 沉脉) primarily indicates interior conditions, belongs to the zang organs and yin. Only with heavy pressure can it be felt and understood by the mind. If deep and touching the bone, it is the Hidden Pulse (Fu Mai, 伏脉), indicating deep pathogenic factors; if deep and hard at the bottom (similar to Ge but Ge is floating while Lao is deep), it is the Firm Pulse (Lao Mai, 牢脉), indicating excessive cold; if deep, fine, and soft, it is the Weak Pulse (Ruo Mai, 弱脉), indicating deficiency search (blood deficiency). When Deep combines with three other pulses, one must adhere to established rules.
Slow (Chi Mai, 迟脉) primarily indicates cold, and also indicates zang diseases (as Zhang Zhongjing stated: "Slow indicates zang"; *Mai Jing* states: "Slow indicates cold"). Two to three beats per breath cycle can be estimated. If slightly slow but not deviating from the normal four-beat rhythm, it is the Moderate Pulse (Huan Mai, 缓脉), which is most beautiful (indicating no disease). If slow and unsmooth (irregular flow), it is the Choppy Pulse (Se Mai, 涩脉), indicating blood stasis (blood deficiency). If slow and occasionally stopping (without fixed number), it is the Knotted Pulse (Jie Mai, 结脉), indicating qi stagnation and phlegm retention. If the stop is regular, it is the Intermitting Pulse (Dai Mai, 代脉): Cu (Surging/Intermitting fast) stops within a rapid rate; Jie stops within a slow rate; both have irregular intervals. If there is a fixed interval, it is Dai. Generally, Dai appears in three or four beats per breath, with fixed stopping intervals. Dai often indicates death (qi exhaustion), except when seen in pregnant women, which is acceptable. When Slow combines with four other pulses, each has its own order.
Rapid (Shu Mai, 数脉) primarily indicates heat, and also indicates fu diseases (as Zhang Zhongjing stated: "Rapid indicates fu"; *Mai Jing* states: "Rapid indicates heat"). Five beats or more per breath cycle, up to seven or eight, may lead to death. If rapid and smooth, it is the Slippery Pulse (Hua Mai, 滑脉), indicating phlegm covering (phlegm and food retention; if clear under fingers, it indicates harmonious qi). If rapid and twisting/tight, it is the Tight Pulse (Jin Mai, 紧脉), attacking with cold (indicating cold and pain). If rapid with stops, it is the Surging-Intermitting Pulse (Cu Mai, 促脉), baking with heat (yang pathogen sinking inward). If Rapid is seen at the Guan position (middle cun), where it feels like a shaking bean, it is the Moving Pulse (Dong Mai, 动脉), indicating uterine bleeding (sudden blood loss due to yin-yang conflict). When Rapid combines with four other pulses, do not remain vague.
Fine (Xi Mai, 细脉) primarily indicates various deficiencies, resembling spider threads. The pulse channel belongs to yin, allowing one to infer the condition. If fine and indistinct, it is the Micro Pulse (Wei Mai, 微脉), indicating qi disaster (exhaustion of yin and yang qi). If fine, small, and floating (fine refers to the thread-like shape, small refers to the weak momentum, combined with floating, like cotton wool floating on water), it is the Soggy Pulse (Ru Mai, 濡脉), indicating prolonged dampness (also indicating qi deficiency, combining with Floating). If fine, small, and deep, it is the Weak Pulse (Ruo Mai, 弱脉), indicating loss of nourishment (blood deficiency, combining with Deep). Among Fine, three other pulses must be distinguished clearly.
Large (Da Mai, 大脉) primarily indicates various excesses, easily known by its broad shape. Yang pulse diseases suggest pathogenic excess. If large and surging/boiling, it is the Surging Pulse (Hong Mai, 洪脉), governing heat (indicating heat excess, also internal deficiency, combining with Floating). If large and combined with hardness, it is the Excess Pulse (Shi Mai, 实脉), holding pathogenic excess. When Large combines with two other pulses, the disease should be examined appropriately.
Short (Duan Mai, 短脉) primarily indicates inherent weakness, not caused by disease injury. Up and down align, shrinking and not extending long. When other pulses combine with this, tonifying yin and yang is appropriate. Moving Pulse belongs to Short, treatment methods discussed separately.
Long (Chang Mai, 长脉) primarily indicates inherent strength, rarely obtained. Extending above Yingji (大鱼际) and below Chize (尺泽), stretching far without shortness. For regulating healthy qi, Long combined with Moderate is ideal. If it is yang pathogen, it surges under fingers. If Excess Pulse is seen within, separate clauses apply.
The above eight pulses are clearly visible. Taking the visible as the outline allows inferring what is not easily seen, making the invisible visible. The combination of eight pulses cannot be fully exhausted by items; all can be deduced by this method.
