指纹何故乍然浮，邪在皮肤未足愁。
腠理不通名表证，急行疏解汗之投。
（此纹与太渊脉相通，凡有外邪，太渊脉浮，此纹亦浮。盖邪在皮毛腠理之间，故指纹
亦显露于外，谓之表证，速宜疏散，启其皮毛，开其腠理、使邪随微汗而解，一剂成功，何
嫌而不投哉。）
忽尔关纹渐渐沉，已知入里病方深。
莫将风药轻相试，须向阳明里证寻。
（指纹见沉，知邪入里，但有浅深之别。若往来寒热，指纹半沉，尚在阳明胃经，治宜
解肌。若外证壮热不已，指纹极沉，已入于阳明胃府，速宜攻下。庸妄见其身热，犹以风药
治之。盖病在内治其外，非其治也，不特病邪不解，适足以燥其阴血，愈增其困耳。）
身安定见红黄色，红艳多从寒里得。
淡红隐隐本虚寒，莫待深红化为热。
（神气太然，营卫静谧，定见太平景象。盖黄为中和之气，红乃衣冠文物之色，红黄隐隐，
景物熙熙，焉有不安之理？寒邪初入皮毛，经络乍滞，所以纹见红鲜，由血滞也。无论内寒
外寒，初病久病，一见此纹，总皆寒证。凡人中气怯，则荣卫不充，纹必淡莹，淡而兼红，
虚寒之应，至谓深红化热，其理安在？红本寒因，岂能热？由其寒闭皮毛，腠理不通，盖人
身
毛
关纹见紫热之征，青色为风古所称。
伤食紫青痰气逆，三关青黑祸难胜。
（营行脉中，卫行脉外，热壅经络，阻其阴荣之道，所以纹紫，紫为热炽，千古定评也
。少阳甲木，其色本青，肝胆受邪，纹见青色，此伤风候也，夫青者木之色，《内经》有在
天为风，在地为木之言，所以风木同气，肝受风邪，纹必现紫色而兼青。食伤之候，盖食饮
有形之物，阻抑中焦，壅遏脾气，不能宣布，故风木乘其困而侮之，所以痰气上逆也。疏通
壅滞，令其疏得可也。倘抑郁既久，脾气愈不运，营卫愈见涩，则风痰食热固结中焦，所以
青而兼黑，此抑郁之至也。急宜攻下，庶有生机。误认惊风，百无一救。）
Why does the fingerprint suddenly float? This is because the pathogenic factor is in the skin layer, which is not yet a cause for concern.
Obstruction of the couli (interstices) is termed Exterior Syndrome (Biao Zheng). One should immediately employ methods to disperse the exterior and induce sweating.
(This fingerprint connects with the Taiyuan pulse. Whenever an external pathogen is present, the Taiyuan pulse floats, and this fingerprint also floats. Since the pathogen resides between the hair follicles and couli, the fingerprint becomes visible externally, which is called Exterior Syndrome. It is urgent to disperse it, open the hair follicles, and unblock the couli, allowing the pathogen to resolve through slight sweating. One dose can achieve success; why hesitate to administer it?)
Suddenly, the fingerprint at the Guan position gradually sinks, indicating that the pathogen has entered the interior and the disease is just beginning to deepen.
Do not rashly try wind-dispelling drugs; one must seek treatment targeting Interior Syndromes of the Yangming channel.
(A sinking fingerprint indicates the pathogen has entered the interior, though there are differences in depth. If there is alternating fever and chills and the fingerprint is half-sunken, the pathogen remains in the Yangming Stomach Channel; treatment should focus on releasing the muscle layer. If external symptoms show persistent high fever and the fingerprint is extremely sunk, the pathogen has entered the Yangming Stomach Organ; rapid purgation is required. Quack doctors, seeing body heat, still use wind-dispelling drugs. Treating an internal disease by addressing the exterior is incorrect; not only will the pathogen not be resolved, but it will also dry up yin blood, worsening the patient's condition.)
When the body is stable and red-yellow colors are seen, bright red often arises from cold syndromes.
Faint redness hidden within originally indicates deficiency-cold; do not wait until deep red transforms into heat.
(The spirit is tranquil, and Ying and Wei Qi are calm, signifying a state of peace. Yellow represents the harmonious qi, and red is the color of ceremonial attire. Faint red and yellow together suggest a harmonious scene, so why would there be instability? When cold pathogens first invade the skin and hair, meridians temporarily stagnate, causing the fingerprint to appear bright red due to blood stasis. Whether internal or external cold, whether early or late stage, seeing this fingerprint always indicates a cold syndrome. People with weak Middle Qi have insufficient Ying and Wei Qi, so their fingerprints appear faint and luminous. Faintness combined with red reflects deficiency-cold. As for the idea that deep red transforms into heat, what is the logic? Red originates from cold; how can it be heat? It is because cold closes the skin and blocks the couli... [text gap] ...the Guan fingerprint showing purple is a sign of heat, while cyan indicates wind, as stated in ancient texts.
Food stagnation, purple and cyan colors, and rebellious phlegm-qi; cyan and black across the three sections signify an incurable disaster.
(Ying Qi circulates within the vessels, while Wei Qi circulates outside. Heat obstructing the meridians blocks the pathway of Yin and Ying, causing the fingerprint to turn purple; purple signifies blazing heat, an established verdict throughout history. Shaoyang Jia Wood naturally has a green/cyan color. When the Liver and Gallbladder are affected by pathogens, the fingerprint shows cyan, indicating Wind-Cold injury. Cyan is the color of Wood; as the *Neijing* states, "In heaven it is Wind, on earth it is Wood." Thus, Wind and Wood share the same resonance. When the Liver is attacked by Wind pathogens, the fingerprint appears purple mixed with cyan. Regarding food injury: tangible food items obstruct the Middle Jiao, blocking Spleen Qi and preventing its dissemination. Consequently, Wind-Wood takes advantage of this distress to insult it, leading to rebellious phlegm-qi. One should clear the obstruction and allow free flow. If depression persists, Spleen Qi fails to transform further, and Ying and Wei become more stagnant. Then Wind, Phlegm, Food, and Heat consolidate in the Middle Jiao, appearing cyan mixed with black, representing extreme depression. Urgent purgation is needed to preserve life. Misdiagnosing this as Convulsive Disorder (Jing Feng) leaves less than one in a hundred chances of survival.)
