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！
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!
