小儿三岁以前，若有疾病，须看虎口三关脉纹，次辩何样以知病源，再看五色，以知深浅吉凶。红黄病浅，青紫病
深，黑至重。男左女右察之。
初起寅关浅，纹形过卯深，生枝终不治，辰位实难禁。五指稍头冷，惊来未可安。若逢中指热，必定是伤寒。中指
独自冷，痧痘证相传。女右男分左，分明仔细看。
当辨左手之纹，病应心肝；右手之纹，病应脾肺。放此消息之，凡纹透甲者死，纹黑死。
凡纹向内者，虽重可治。如弓反外，病轻必重，难治。如流珠形见于关口或面俱不治。

Before the age of three, if a child is ill, one must observe the pulse pattern on the three palaces of the tiger's mouth (the thenar eminence area), distinguish its shape to identify the disease source, and examine the five colors to determine the depth and prognosis. Red and yellow indicate superficial disease; cyan and purple indicate deep-seated disease; black indicates severe condition. Observe the left hand for males and the right hand for females.
At the onset, if the pattern is shallow in the Yin Palace (Wind Palace), it indicates a mild condition; if the pattern extends to the Mao Palace (Qi Palace), the disease has deepened; if branches appear, it is incurable; if it reaches the Chen Palace (Life Palace), it is difficult to withstand. Coldness at the tips of the five fingers suggests convulsions have occurred, and peace cannot be assured. If the middle finger is hot, it is definitely wind-cold damage (Shanghan). If the middle finger alone is cold, it indicates measles or smallpox patterns. Distinguish clearly between right for females and left for males, observing carefully.
When distinguishing the patterns on the left hand, the disease corresponds to the Heart and Liver; on the right hand, it corresponds to the Spleen and Lung. Deduce from this principle. Any pattern penetrating the nail bed indicates death; a black pattern indicates death. Patterns extending inward (towards the wrist), although severe, are treatable. If the pattern curves outward like a bow, a light disease becomes heavy and difficult to treat. If a "flowing pearl" shape appears at the gate or on the face, it is untreatable.
\rThree Palaces Diagram\p03-b7a2.bmp\r
One: Wind Palace, easy to treat; Two: Qi Palace, deep disease; Three: Life Palace, difficult to treat.
Fish-spine pattern: Indicates initial fright; Needle-hanging shape: Common in diarrhea and dysentery; Water-character shape: Indicates lung accumulation due to fright; Yi-character shape: Often a misjudgment related to the Liver; Curved-worm shape: Indicates fright and malnutrition diseases; Bow-ring shape: One theory suggests passing the critical stage; Chaotic lines: Severe case of worm infestation; Flowing-pearl shape: Disease is already critical.
\rFish-spine Pattern & Needle-hanging Shape\p03-b7a1.bmp\r
Fish-spine pattern ○ The shape resembles fish bones, indicating initial fright. The whole body feels hot like boiling water, the complexion is cyan, accompanied by vomiting, diarrhea, and restlessness. If the intestines are unblocked and qi harmonizes, the child will regain consciousness.
Needle-hanging shape ○ The shape resembles a hanging needle, common in diarrhea and dysentery. It involves fright and fever, definitely causing discomfort. If this disease transforms into slow convulsions and the pattern has passed the Life Palace, it is a critical condition.
\rWater-character, Yi-character, & Curved-worm Shapes\p03-b7a4.bmp\r
Water-character shape ○ Resembling the character "water," it indicates lung fright and chronic accumulation, with a cyan complexion. Phlegm above the diaphragm requires treatment; if the pattern has passed the Life Palace, life is hard to save.
Yi-character shape ○ Resembling the character "yi," the cause lies in the Liver, manifesting as strabismus, slow convulsions, crying, and intermittent spasms. Caused by long-term cold accumulation transforming, when slow spleen wind passes the three palaces...
Curved-worm shape ○ Resembling a curved snake, the disease is deep, involving spleen accumulation, malnutrition, and fright. If it has not passed the second palace, treat early; if it passes the third palace, discussion is futile.
\rIncoming Snake, Outgoing Snake, & Incoming-Outgoing Snake Shapes\p03-b7a3.bmp\r
Incoming snake shape ○ Indicates food stagnation and accumulation, with abdominal discomfort and frequent whimpering. Taking Shiquan Decoction is an effective prescription; there is no need to seek gods or worship Buddhas.
Outgoing snake shape ○ Symptoms are mostly wind-heat, with malnutrition transforming into this shape. High fever and confusion require dispersing methods; if it reaches the third palace, the condition is serious.
Incoming-outgoing snake shape ○ Indicates internal and external deficiency, with spleen heat causing sparse hair. Support the spleen, nourish the stomach, and eliminate malnutrition; if the Life Palace is reached, medication is useless.
\rBowed Bow, Jade Ring, & Chaotic Line Shapes\p03-b7a6.bmp\r
Bowed bow shape ○ Resembling a bow, it indicates malnutrition consumption (Gan Lao). Muscles are emaciated, and internal heat burns like fire. Treat similarly to the ring shape to avoid future weeping.
Jade ring shape ○ Resembling a ring bow, it evaluates as malnutrition accumulation. The patient frequently eats dirt, cloth, charcoal, and tea. Urgently use medicines to dissipate malnutrition and strengthen the spleen; if it passes the third palace, life is lost.
Chaotic line shape ○ Chaotic lines leave no doubt about the illness. Day and night crying is rare among those who recognize it. Take Yulu Ointment once, and parents will surely smile.
\rDouble Ring, River Character, & Flowing Pearl Shapes\p03-b7a5.bmp\r
Double ring shape ○ Appears in the Qi Palace. Red and purple indicate wind pathogen; cyan indicates cold. Recognize the syndrome early and seek good medicine; if all three palaces are involved, death is inevitable.
River character shape ○ Resembling the character "chuan" across the three palaces. Purple, red, and yellow patterns are acceptable. Treatment is the same as for chaotic lines; if cyan and black meet, life is difficult to save.
Flowing pearl shape ○ A malignant sign requiring urgent medical attention. The disease affects the Gao-Huang (deep interior) and cannot be cured. If seen in the Sanjian area, do not hope for the child; arrange funeral affairs without doubt.
