老弱之人，脉宜缓弱；若过旺者，病也。少壮之人，脉宜充实；若过弱者，病也。然又有说焉。老人
脉旺而非躁者，此天禀之浓，引年之叟也，名曰寿脉；若脉躁疾，有表无里，则为孤阳，其死近矣。壮者脉
细而和缓，三部同等，此天禀之静，清逸之士也，名曰阴脉；若细小劲直，前后不等，可以决死期矣。

逐脉审察者，一定之矩也；随人变通者，圆机之士也。肥盛之人，气居于表，六脉常带浮洪；瘦小之人，
气敛于中，六脉常带沉数。性急之人，五至方为平脉；性缓之人，四至便作热看。身长宜疏下指；身短宜密下
指。北人多实；南人多弱。酒后之脉常数；饭后之脉常洪。远行必疾；久饥必虚。室女常
濡；婴儿常数。经曰∶“形气相得者生，三五不调者死。”其可不察乎！
以寸关尺三部言之，尺为根，关为干，寸为枝叶。若尺部
无神，则无根矣。以浮中沉三候言之，沉候为根，中候为干，浮候为枝叶。若沉候不应，则无根矣。
阴搏阳别，谓之有子。（谓尺中之阴脉搏大，与寸部之阳部迥别者，乃有子也。）阴虚阳搏，谓
之崩。（阴虚，血衰于下，则阳火上亢矣。血为火迫，不得而安其位，乃为崩漏之疾。）手少阴脉动甚者，
妊子也。（手少阴者，心脉也。动甚者，形如豆粒，急数有力也。心
主血，血旺乃能成胎。心脉动甚，血旺之象，故当妊子。）
滑伯仁曰∶“三部脉浮沉正等，无他病而不月者，为有妊也。得太阴脉为男，得太阳脉为女。太阴
脉沉，太阳脉浮。左疾为男，右疾为女。左右俱疾，为生二子。尺脉左大为男，右大为女。左右俱大，产二子。”
“左手沉实为男，右手浮大为女。左右手俱沉实，猥生二男；左右手俱浮大，猥生二女。”
“左右尺俱浮，为产二男；不尔则女作男生。（谓一男一女之胎，女胎死而男胎生。）”
左右尺俱沉，为产二女；不尔则男作女生。
“妇人阴阳俱盛，曰双躯。（言左右两尺部俱大而有力也。）若少阴微紧者，血
积凝浊，经养不周，胎则偏夭，其一独死，其一独生。不去其
死，害母失胎。”
“何以知怀子之且生也。岐伯曰∶身有病而无邪脉也。”
（有病，如腹痛拘急之类。无邪脉，谓无病脉也。）妇人欲生，其脉离经，夜半觉，日中则生也。
（离经者，谓离于经常之脉，如昨小今大，昨涩今滑，昨浮今沉之类。夜半觉，日中生子者，子午相冲也。）
妇人经断有躯，其脉弦者，后必血下，不成胎也。（弦者，肝脉也。肝主疏
泄。今见弦，则肝脉太过，不能藏血也。）
妇人尺脉微迟，为居经，月事三月一下。（微迟者，虚寒之脉也。居经，犹云停经也。三
月一下，为血不足也。）
妇人尺脉微弱而涩，少腹冷，恶寒，年少得之为无子；年大得之为绝产。
新产伤阴，出血不止，尺脉不能上关者，死。
For elderly and weak individuals, the pulse should be slow and weak; if it is excessively vigorous, it indicates disease. For young and robust individuals, the pulse should be full and solid; if it is excessively weak, it indicates disease. However, there is another perspective. When an elderly person has a vigorous pulse but not one that is restless or rapid, this indicates strong congenital endowment and longevity; such a person is called a "Longevity Pulse" (Shou Mai). If the pulse is restless and rapid, appearing superficial without depth (having exterior but lacking interior root), it represents solitary Yang floating outward, indicating death is near. When a robust adult has a fine yet harmonious and slow pulse, with equal strength in all three positions (Cun, Guan, Chi), this indicates a tranquil congenital constitution and refined character; such a pulse is called a "Yin Pulse". If the pulse is fine, small, stiff, and straight, with unequal strength between the anterior (Cun) and posterior (Chi) positions, the time of death can be determined.
(Addendum)
Examining each pulse meticulously is a fixed standard; adapting flexibly to individual circumstances belongs to the wise and versatile physician. In obese individuals, Qi resides at the surface, so the six pulses often carry a Floating-Hong (Superficial-Excessive) quality. In thin individuals, Qi is gathered within, so the six pulses often carry a Chen-Shu (Deep-Rapid) quality. In persons with irritable temperaments, five beats per respiration cycle constitute a normal pulse; in persons with calm temperaments, four beats per respiration cycle should be viewed as Heat syndrome. For tall people, fingers should be placed more sparsely; for short people, fingers should be placed more closely. People from the North tend toward Excess patterns; people from the South tend toward Deficiency patterns. The pulse after drinking wine is usually Rapid; the pulse after eating is usually Hong (Excessive/Expansive). After long travel, the pulse must be Rapid; after prolonged fasting, the pulse must be Weak. Unmarried women's pulses are often Ru (Soggy); infants' pulses are often Shu (Rapid). The Classic states: "When Form and Qi are compatible, life prevails; when the pulse is chaotic and irregular, death ensues." How can one fail to examine this carefully!
Speaking of the Cun, Guan, and Chi positions: Chi is the Root, Guan is the Trunk, and Cun is the Branches and Leaves. If the Chi position lacks Shen (Spirit/Vitality), there is no Root. Speaking of the Fu, Zhong, and Chen depths: Chen (Deep) is the Root, Zhong (Middle) is the Trunk, and Fu (Superficial) is the Branches and Leaves. If the Chen depth yields no response, there is no Root.
When the Yin pulse at the Chi position beats vigorously and distinctly differs from the Yang pulse at the Cun position, it signifies pregnancy. (This means the Yin pulse at Chi is large and forceful, clearly distinct from the Yang pulse at Cun, indicating pregnancy.) When Yin is deficient and Yang pulses are vigorous, it signifies Beng (Metrorrhagia/Metrostaxis). (Yin deficiency implies blood depletion below, causing Yang Fire to flare upward. Blood is forced by fire and cannot remain in its proper place, resulting in Beng-Lou [profuse uterine bleeding].) When the Hand-Shaoyin (Heart) pulse moves significantly, it indicates pregnancy. (Hand-Shaoyin refers to the Heart pulse. "Moving significantly" means the pulse feels like a bean grain, urgent, rapid, and forceful. The Heart governs Blood; abundant blood enables conception. A significant Heart pulse movement is a sign of abundant Blood, thus indicating pregnancy.)
Hua Bo-ren said: "If the three positions (Cun, Guan, Chi) have equal Fu-Zhong-Chen qualities, and menstruation has ceased without other diseases, it is pregnancy. Obtaining a Taiyin pulse indicates a male fetus; obtaining a Taiyang pulse indicates a female fetus. Taiyin pulse is Deep; Taiyang pulse is Superficial. A rapid pulse on the left indicates a male; a rapid pulse on the right indicates a female. Rapid pulses on both sides indicate twins. A larger Chi pulse on the left indicates a male; a larger Chi pulse on the right indicates a female. Larger Chi pulses on both sides indicate twins." "A deep-solid pulse on the left hand indicates a male; a floating-large pulse on the right hand indicates a female. Deep-solid pulses on both hands indicate multiple males; floating-large pulses on both hands indicate multiple females." "Floating pulses on both Chi positions indicate two males; otherwise, it is a mixed pair where the female fetus dies and the male survives." "Deep pulses on both Chi positions indicate two females; otherwise, it is a mixed pair where the male fetus dies and the female survives." "When a woman's Yin and Yang pulses are both excessive, it is called 'Shuang Qu' (Double Body), meaning both Chi positions are large and forceful. If the Shaoyin pulse is slightly tight, it indicates blood stasis and turbidity, insufficient nourishment for the fetus, leading to unilateral fetal demise (one dies, one lives). If the dead fetus is not expelled, it will harm the mother and cause the loss of the living fetus."
"How do we know childbirth is imminent? Qibo said: 'The body has symptoms, but the pulse is free of pathological signs.'" (Symptoms include things like abdominal pain and cramping. No pathological signs mean the absence of disease-specific pulses.) When a woman is about to give birth, her pulse deviates from the regular pattern. If she perceives this change at midnight (Zi hour), she will deliver at noon (Wu hour). (Deviation from the regular pattern means changes such as small to large, choppy to slippery, or superficial to deep. Midnight perception and noon delivery occur due to the opposition of Zi and Wu hours.) If a woman has amenorrhea due to pregnancy but the pulse is Xian (Wiry), she will subsequently experience vaginal bleeding and fail to carry the fetus to term. (Xian pulse corresponds to the Liver. The Liver governs free flow and storage of blood. A Xian pulse indicates Liver excess, implying an inability to store blood.)
If a woman's Chi pulse is micro-slow (Wei-Chi), it is called Ju Jing (Residing Menses), where menstruation occurs once every three months. (Wei-Chi is a pulse of deficiency-cold. Ju Jing implies arrested menses. Occurring once every three months indicates blood insufficiency.)
If a woman's Chi pulse is weak, faint, and choppy, accompanied by cold lower abdomen and aversion to cold, if acquired in youth, it indicates infertility; if acquired in old age, it indicates sterility.
After recent childbirth, if Yin is damaged and bleeding does not stop, and the Chi pulse cannot reach up to the Guan position, death ensues.
