阴阳运合。男女成形。已分九窍四肢。乃生五脏六腑。部位既别。逆顺难明。若存寸舌
之浮沉。必乃横亡于孩子。须明虎口辨别。三关消详。用药始无差误。
寝后方将形脉看。要分寅卯辰三关。男看左手女看右。气寅风卯命辰安。纹青枝紫惊为
病。
纹紫枝红伤寒症。红为米粒肺结热。黑色透辰伤暑论。青纹泻痢胃家寒。白色微微即是疳。
枝赤涎潮胸痞膈黄纹隐隐困脾端。枝形宛为钩钓样。伤风伤寒分所向。向外伤风有汗形。向
内伤寒无汗相。枝青浑如鱼刺形。惊疳虚风三部分。枝直悬针青黑色。水惊肺热慢脾 。枝
如水字三关有。咳嗽积滞风疳久。枝如一字青红纹。总是惊风慢脾疾。一曲如环伤食于。两
曲如钩伤冷看。三曲长虫伤硬物。双钩脉样是伤寒。枝形或似如蛇样。定是脾经湿热多乱纹
食指如川字。食积相兼五脏疳。
脐风撮口。总为一病。未有脐风而不撮口。未有撮口而非脐风也。患此病者。九死一生
。盖
心。闭口属脾。风入于脐。先流于脾。由脾而至上传入于心。心为邪所客。故口不能开而频
撮也其发搐者。风使之也。究其病之所由。成有内外因之异。盖脐带系于胞。必其未生之时
。其母先感风邪。遗其邪于小儿。谓之胎风。其惊搐者。谓之胎惊。病从内得。故曰内因。
其或断脐之后。包裹失于周密。被窝风入来。及六七日。而脐带已脱。必成此症病从外得
。故曰外因。有以艾灸其脐。徒苦之耳。竟何益哉。欲求一生于万死之中。惟下之而已矣
。外此更无他法。

阴阳二气运化相合，男女交媾形成胎儿。胎儿成形后，已具备九窍和四肢，进而生成五脏六腑。身体部位既然已经区分明确，疾病发展的逆顺规律便难以明了。如果仅凭寸口脉象的浮沉来判断小儿病情，必然会导致误诊甚至患儿横死。必须通过观察虎口（食指）脉络来进行辨别，详细分析三关（风、气、命）的变化，用药才能没有差错。
通常在夜间就寝后查看指纹形态与色泽。要分清寅、卯、辰三个关卡。男孩看左手，女孩看右手。寅关主气，卯关主风，辰关主命。指纹呈现青色或紫色，多诊断为惊病（受惊吓所致之病）。
指纹呈紫色且分支发红，多为伤寒证；红色如米粒状，提示肺中有结热。黑色纹路透至辰关，诊断为伤暑证。青色纹路多见于泻痢，属胃寒。白色纹路轻微者，即是疳积证。分支赤色，提示涎液上潮、胸膈痞闷；黄色纹路隐隐约约，提示脾经困顿。分支形状宛如钩钓样，用于区分伤风与伤寒的方向。向外斜出的指纹，多为有汗的伤风证；向内斜出的指纹，多为无汗的伤寒证。分支青色，整体如同鱼刺形状，分为惊、疳、虚风三部分。分支直挺如悬针状，颜色青黑，提示水惊、肺热或慢脾风。分支纹路如水字形状贯穿三关，提示咳嗽、积滞或久治不愈的风疳。分支纹路如一字形，颜色青红相间，总是属于惊风或慢脾疾病。弯曲如环状，提示伤食；两个弯曲如钩状，提示伤冷；三个弯曲长条状，提示寄生虫或硬物损伤；双钩脉象则是伤寒的表现。分支形状若似蛇形，定是脾经湿热，伴有杂乱纹路。食指指纹如川字形，提示食积兼有五脏疳证。
脐风撮口，总归是一种疾病。没有患脐风却不出现撮口症状的，也没有出现撮口症状而非脐风的。患有此病的人，十有八九死亡，仅有一线生机。盖因心主舌，闭口属脾。风邪侵入脐部，先流窜于脾，由脾上传入心。心被邪气所客居，所以口不能张开而频繁撮缩。其发作抽搐，是由风邪引起的。究其病因，有内因和外因的区别。脐带系于胞宫，必定是在未出生之前，母亲先感受风邪，将邪气遗留给小儿，这称为胎风。其出现的惊厥抽搐，称为胎惊。病从体内获得，所以称为内因。或者是断脐之后，包裹护理不够周密，被窝中的风邪侵入，等到六七天后，脐带脱落，必然形成此症。病从体外获得，所以称为外因。有人用艾灸脐部治疗，只是徒增痛苦罢了，究竟有什么益处呢？想要在万死之中求得一线生机，只有采用下法（攻下泄实）而已。除此之外，没有其他方法。

Yin and Yang Qi (Vital Energy) circulate and combine, male and female essence joins to form the fetus. After formation, the nine orifices and four limbs are established, followed by the generation of the Zang-Fu organs (internal organs). Since the body parts are distinctly separated, the favorable and unfavorable progression of diseases becomes difficult to discern. If one relies solely on the floating or sinking pulse at the Cun position (radial artery), it will inevitably lead to misdiagnosis and sudden death of the child. One must clearly distinguish using the Tiger's Mouth (the web between thumb and index finger) patterns, carefully analyzing the Three Sections (Wind, Qi, Life sections on the infant's index finger), so that medication is administered without error.
Typically, observe the shape and color of the fingerprint after the child falls asleep at night. Distinguish the three sections: Yin (Wind section), Mao (Qi section), and Chen (Life section). For boys, examine the left hand; for girls, the right hand. The Wind section governs Qi, the Qi section governs Wind, and the Life section governs stability. A blue or purple fingerprint indicates illness due to Fright (Shock/Startle).
A purple fingerprint with red branches indicates Cold Damage Syndrome (Shanghan); red spots resembling rice grains suggest Heat accumulation in the Lungs. Black lines extending to the Life section indicate Summerheat Injury. Blue lines are associated with diarrhea and dysentery, indicating Stomach Cold. Slight white lines indicate Infantile Malnutrition (Gan Syndrome). Reddish branches suggest excessive saliva, chest fullness, and diaphragmatic obstruction; faint yellow lines indicate Spleen deficiency. Branch shapes resembling hooks help differentiate between Wind Strike (Shangfeng) and Cold Damage (Shanghan). Outward-slanting lines indicate Wind Strike with sweating; inward-slanting lines indicate Cold Damage without sweating. Blue lines resembling fish bones are divided into three categories: Fright, Malnutrition, and Deficient Wind. Straight, needle-like lines that are blue-black indicate Water Fright, Lung Heat, or Slow Spleen Wind. Lines resembling the character "Water" across the three sections indicate chronic cough, food stagnation, or wind-related malnutrition. Lines resembling the character "One" with mixed blue-red colors always indicate Fright Wind or Slow Spleen disease. Curves resembling a ring indicate Food Injury; two curves resembling hooks indicate Cold Injury; three long curves indicate Parasite infection or injury from hard objects; double-hook pulse patterns indicate Cold Damage. Snake-like branch shapes indicate Damp-Heat in the Spleen channel, accompanied by chaotic lines. A "Chuan" (river) shaped fingerprint on the index finger indicates Food Stagnation combined with Five Organs Malnutrition.
Umbilical Tetanus with Mouth Contraction is considered a single disease entity. There is no case of Umbilical Tetanus without mouth contraction, nor is there mouth contraction that is not Umbilical Tetanus. Patients suffering from this disease have only one chance of survival out of ten. This is because the Heart governs the tongue, and mouth closure relates to the Spleen. Wind pathogen enters the umbilicus, first flows into the Spleen, and then transmits upward to the Heart. When the Heart is occupied by evil pathogens, the mouth cannot open and frequently contracts. The convulsions are caused by Wind. Investigating the etiology, there are differences between internal and external causes. The umbilical cord is connected to the uterus; before birth, if the mother was previously exposed to Wind pathogen, she may transmit this pathogen to the infant, called Fetal Wind. The resulting convulsions are called Fetal Fright. Since the disease originates internally, it is termed an Internal Cause. Alternatively, after cutting the umbilical cord, if wrapping care is not meticulous, wind from the bedding may invade. By the sixth or seventh day, when the umbilical cord falls off, this syndrome inevitably develops. Since the disease originates externally, it is termed an External Cause. Some practitioners use moxibustion on the umbilicus, which merely causes suffering and offers no benefit. To seek survival amidst near-certain death, only purgative methods (downward-draining techniques) can be used. There are no other methods beyond this.
