小儿在三岁以内，诊脉时需要参看虎口部位的脉络。
男婴看左手，女婴看右手，食指分为风关、气关、命关三关。
没有疾病时，指纹难以辨认，颜色隐现为淡红或淡黄色。
颜色鲜明则表明有病患，青色主惊风，白色主疳积。
紫色表示受风邪侵袭，红色表示发热兼夹伤寒。
黑色表示中恶邪极重，黄色表示食积导致脾脏受损。
青黑相间且指纹细长者，主慢惊风；指纹过多者，主气机紊乱。
指纹向内延伸至手掌，提示病情危重，危及生命。
（附：三关指掌图）
初关（第一节）出现指纹容易治疗，二关（第二节）出现指纹病势沉重，三关（第三节）出现指纹难治。
（附图一说明）
初关指纹见红赤色为风热证，见青紫色为惊积证，见黑紫色主凶险，若透至第二关则危险，透至第三关必死无疑。初关指纹隐约可见、辨识不清者，主慢惊风。
（附图二说明）
寅关（此处疑为“初关”之误或特定称呼，结合上下文指第一关）指纹见浅青色，主大便青色伴腹痛；深青色主惊悸；青黑色主惊搐及内钓证；浅红色主内热，或呕吐腹泻不能吃奶；红赤色主惊热；深紫色主烦躁惊哭；杂乱无章的指纹主伤乳或呕吐腹泻。
（附图三说明）
红色指纹表示热证轻浅，青色指纹确定是惊风，紫色指纹表示病情加重，黑色指纹预示死亡。黄色指纹隐约可见，表示安宁无病蔓延。若有纹侵入手掌，主内吊证病程缠绵。凡是透达三关的，神仙也难以治愈。
（附图四说明）
五指梢头发冷，是惊风发作，不可安宁。
如果中指发热，必定是伤寒。
如果只有中指独自发冷，需参考麻疹和天花的症状进行判断。
男婴看左手，女婴看右手，要分明仔细地观察。

In children under three years of age, pulse diagnosis requires examining the veins at the tiger's mouth (the radial aspect of the wrist).
For boys, examine the left hand; for girls, the right hand. The index finger is divided into three sections: the Wind Gate (Feng Guan), Qi Gate (Qi Guan), and Life Gate (Ming Guan).
When healthy, the vein pattern is difficult to discern, with a color that is faintly visible, appearing pale red or pale yellow.
A distinct color indicates illness: cyanosis suggests fright-convulsion (Jing Feng), while pallor suggests malnutrition syndrome (Gan Ji).
Purple indicates invasion by wind pathogen; red indicates heat accompanied by cold damage (Shang Han).
Black indicates extreme poisoning by evil qi; yellow indicates spleen dysfunction due to food stagnation.
Cyanosis mixed with black and long veins indicate slow convulsion (Man Jing); excessive veining indicates chaotic vital energy (Qi Luan).
If the vein extends into the palm, it signals critical danger to life.
(Reference: Diagram of Three Gates on Finger and Palm)
Veins appearing at the first gate (Wind Gate) are easy to treat; those at the second gate (Qi Gate) indicate severe disease; those at the third gate (Life Gate) are difficult to treat.
[Diagram 1 Description]
Reddish veins at the first gate indicate wind-heat; cyanotic-purple veins indicate fright and accumulation; black-purple veins indicate ominous prognosis. If extending to the second gate, it is critical; if extending to the third gate, death is inevitable. Faintly visible, indistinct veins at the first gate indicate slow convulsion.
[Diagram 2 Description]
Light cyan veins at the first gate indicate green stools and abdominal pain; deep cyan veins indicate palpitations and fright; cyan-black veins indicate convulsions and internal hooking (Nei Diao); light red veins indicate internal heat, vomiting, diarrhea, or refusal to nurse; reddish veins indicate fright-heat; deep purple veins indicate restlessness and crying from fright; chaotic veins indicate milk injury, vomiting, or diarrhea.
[Diagram 3 Description]
Red veins indicate mild heat; cyan veins confirm fright; purple veins indicate worsening condition; black veins signal death. Faintly visible yellow veins indicate peace and absence of spreading disease. Veins invading the palm indicate persistent internal hooking disease. Any vein penetrating all three gates is incurable even by immortals.
[Diagram 4 Description]
Cold fingertips indicate onset of fright, causing unrest.
Heat in the middle finger indicates cold damage (Shang Han).
Coldness isolated to the middle finger requires reference to symptoms of smallpox and measles.
Examine the left hand for boys and the right hand for girls, observing clearly and carefully.
A newborn whose cries are continuous and connected has a long life.
A newborn whose cries cease and then resume abruptly has a short life.
Scattered cries indicate inability to reach adulthood.
Deep cries indicate inability to reach adulthood.
A small umbilicus indicates short life.
General softness as if boneless indicates short life.
Sweating blood indicates misfortune and short life.
Urine coagulating like paste indicates inability to reach adulthood.
Constant shaking of hands and feet indicates inability to reach adulthood.
Incomplete hair growth indicates inability to reach adulthood.
Incomplete development of the occipital bone allows speech but leads to early death.
Incomplete development of metacarpal bones allows crawling but leads to early death.
Incomplete development of patellae allows standing but leads to early death.
Incomplete development of calcaneus allows squatting but leads to early death.
Body unable to maintain normal posture results in death.
Lack of flesh between thighs results in death.
Fish-mouth deformity (genital anomaly) results in death.
White skin below the scrotum results in death; red skin below the scrotum also results in death.
