指纹淡淡亦堪惊，总为先天赋禀轻。脾胃本虚中气弱，切防攻伐损胎婴。
（小儿禀受阳虚，肌肤晃白，唇舌淡色者，指纹四时皆淡，虽有病亦止淡红淡青淡紫而已。盖淡红虚寒，淡青
虚风，淡紫虚热。此等之儿根本不坚，中气怯弱，无论新病久病，总归于虚，一毫攻伐，不敢轻用，倘误投克
削，覆水难收，悔之迟矣。）
关纹涩滞甚因由，邪遏阴荣卫气留。食郁中焦风热炽，不行推荡更何求？
（病邪阻郁荣卫，营运迟滞，升降羁留，所以指纹推之转涩，全无活泼流利之象。由食饮风热相搏，是为实
证，急宜推荡，去其菀
，其愈亦易。若三关纯黑，推之不动，死证也，不治。）
腹痛纹入掌中心，弯内风寒次第侵。纹向外弯痰食热，水形脾肺两伤阴。
（掌心包络所主，纹入掌中，邪侵五内，由中气寒也，故为腹痛。纹若弯弓，内外有别∶其纹之两头弯向中
指为内，为顺证，为外感风寒，治之犹易；其纹弯向大指为外，为逆证，为内伤饮食，治之稍难。形如“水”
字，脾肺不足，食塞太阴，中气怯弱，脾不运化故也。或问指纹惟止一线，安能如水字之形？曰∶不观太渊之
脉，亦止一线，何以阳维、阴维、阳跷、阴跷，皆左右弹石，岂非小字之形乎？脉有左右，安知纹无左右？但
能触类旁通，无往非理，岂特指纹为然哉！）
凡看指纹，以我之大拇指侧面，推儿食指三关，切不可覆指而推。盖螺纹有火，克制肺金，纹必变色。又只
可从命关推上风关，切不可从风关推出命关。此纹愈推愈出，其纹在先，原未透关，今误推而出之，大损肺
气，慎之戒之！
以上表里寒热虚实，凿凿有据，但能于临证时，认得此六字分明，胸中自有主宰，虽不中，不远矣。若但
以惊证塞责，何难应对，第晨盅自问，未免怀惭。凡我同人，互为砥砺，幸矣！
指纹颜色浅淡也令人惊惧，这总归是因为先天禀赋薄弱。脾胃本已虚弱，中气不足，务必防止使用攻伐药物损伤胎婴（小儿）。
（小儿如果禀受阳气不足，肌肤苍白，嘴唇和舌头颜色淡白，那么指纹在四季之中都呈现淡色，即使生病，也只是淡红、淡青或淡紫而已。大概淡红色代表虚寒，淡青色代表虚风，淡紫色代表虚热。这类孩子根本不坚固，中气怯弱，无论是新病还是久病，总归属于虚证，丝毫不能轻易使用攻伐药物，倘若误投克削之药，后果如覆水难收，后悔就晚了。）
关部指纹涩滞的原因何在？那是邪气遏制了阴分，营卫之气留滞不行。食积停滞在中焦，风热炽盛，如果不进行推荡祛除，还能寻求什么治愈之道呢？
（病邪阻郁营卫，导致营运迟滞，升降受阻，所以指纹推按时感觉转涩，完全没有活泼流利的景象。这是由于饮食积滞与风热相互搏结，属于实证，急需推荡祛邪，去除郁结，痊愈也容易。如果三关指纹纯黑，推之不动，这是死证，无法治疗。）
腹痛时指纹延伸至手掌中心，向内弯曲表示风寒依次侵袭。指纹向外弯曲则是痰、食、热所致，形如水字则说明脾肺两脏阴液受损。
（掌心由心包络所主，指纹进入掌中，表示邪气侵犯五脏内部，这是因为中气寒凉，所以引起腹痛。指纹若像弯弓一样，内外是有区别的：指纹的两头弯向中指为内，属于顺证，是外感风寒，治疗还比较容易；指纹弯向大拇指为外，属于逆证，是内伤饮食，治疗稍微困难。形状像“水”字，是脾肺不足，食物堵塞太阴经，中气怯弱，脾脏不能运化的缘故。有人问：指纹只有一条线，怎么能形成水字的形状呢？回答说：没看过太渊穴的脉象吗？也只有一条线，为什么阳维脉、阴维脉、阳跷脉、阴跷脉，都会左右弹石般跳动，难道不是小字的形状吗？脉有左右之分，怎么知道指纹没有左右之分呢？只要能触类旁通，无处不合乎道理，哪里只是指纹如此呢！）
凡是观察指纹，要用我的大拇指侧面，推按孩子的食指三关，切不可覆盖指腹去推。因为螺纹中有火，会克制肺金，指纹必然变色。而且只能从命关推向风关，切不可从风关推出命关。这种指纹越推越显露出来，原本它的纹在先，并没有透过关窍，现在错误地推出来了，极大地损伤肺气，一定要谨慎戒除！
以上关于表里、寒热、虚实的判断，都有确凿的依据，只要在临证时能清楚分辨这六个字，心中自然就有主宰，虽然不一定完全命中，但也相去不远了。如果只是用惊证来搪塞责任，应对起来并不难，但每当早晨自问，未免感到惭愧。希望各位同行互相勉励，那就太好了！
The faintness of the fingerprint is also alarming; it generally indicates a weak congenital constitution. The Spleen and Stomach are inherently deficient, with weak Middle Qi (Central Qi); one must strictly guard against using attacking/draining methods that could damage the infant.
(If a child has inherited Yang deficiency, presenting with pale skin and pale lips and tongue, the fingerprint will be faint in all four seasons. Even if ill, it will only appear as faint red, faint green, or faint purple. Generally, faint red indicates Deficiency-Cold, faint green indicates Deficiency-Wind, and faint purple indicates Deficiency-Heat. Such children have an unstable root and weak Middle Qi. Regardless of whether the disease is new or chronic, it always falls under Deficiency patterns. One dare not lightly use any attacking/draining methods. If mistakenly prescribed harsh draining herbs, the consequences are irreversible, and regret would come too late.)
What is the reason for the rough and stagnant appearance at the Guan position? It is due to pathogenic factors obstructing the Yin, causing Ying (Nutritive) and Wei (Defensive) Qi to stagnate. Food retention in the Middle Jiao (Middle Burner) and blazing Wind-Heat: if one does not employ pushing and purging methods, what else can be sought for cure?
(Pathogenic factors obstruct and depress Ying and Wei Qi, causing sluggish circulation and impaired ascending/descending movements. Thus, when pushing the fingerprint, it feels rough, lacking vitality and smoothness. This results from food retention clashing with Wind-Heat, constituting an Excess pattern. Urgent pushing and purging are required to remove the accumulation, after which recovery will be easy. If the three sections of the finger show pure black color and do not move upon pushing, it is a death sign and incurable.)
When abdominal pain occurs, if the fingerprint extends into the center of the palm, inward curvature indicates sequential invasion by Cold and Wind. Outward curvature indicates Phlegm, Food retention, and Heat. A shape resembling the character "Water" indicates injury to the Yin of both the Spleen and Lungs.
(The palm center is governed by the Pericardium. Fingerprint entering the palm signifies pathogenic invasion of the five internal organs, caused by Cold in the Middle Qi, thus leading to abdominal pain. Regarding the bow-like curvature: if the two ends of the fingerprint curve toward the middle finger, it is "inward," representing a favorable syndrome (Shun Zheng), caused by external contraction of Cold and Wind, which is relatively easy to treat. If the fingerprint curves toward the thumb, it is "outward," representing an unfavorable syndrome (Ni Zheng), caused by internal injury from diet, which is slightly more difficult to treat. A shape like the character "Water" indicates insufficiency of the Spleen and Lungs, food blocking the Taiyin meridian, weak Middle Qi, and the Spleen's failure to transform and transport. One might ask: Since the fingerprint is merely a single line, how can it form the shape of the character "Water"? I reply: Have you not observed the pulse at Taoyuan (LU9)? It is also a single line, yet why do the Yang Linking Vessel, Yin Linking Vessel, Yang Heel Vessel, and Yin Heel Vessel all pulse left and right like stones striking rock, forming a small character shape? Pulses have left and right distinctions; how can we assume fingerprints do not? As long as one can draw inferences by analogy, everything aligns with principle, not just fingerprints.)
When observing the fingerprint, use the side of your thumb to push along the three sections of the child's index finger. Do not cover the finger with your palm while pushing. Because the whorls contain Fire, which controls Lung Metal, the fingerprint color will inevitably change. Furthermore, one should only push from the Ming Guan (Life Gate) toward Feng Guan (Wind Gate), never from Feng Guan out toward Ming Guan. If the fingerprint becomes more exposed with pushing, it means the original mark did not penetrate the section, but was erroneously pushed out, severely damaging Lung Qi. Be cautious and beware!
The above judgments regarding Exterior/Interior, Cold/Heat, and Deficiency/Excess are well-founded. If one can clearly distinguish these six characters during clinical practice, one will naturally have mastery over the situation. Although one may not hit the mark perfectly, one will not be far off. If one merely uses "Fright Syndrome" as an excuse to shirk responsibility, responding is not difficult, but self-reflection each morning brings shame. I hope my colleagues will encourage and sharpen each other; this would be fortunate indeed!
