初生小儿诊虎口，男从左手女右看，次指三节风气命，脉纹形色隐隐安，
形见色变知有病，紫属内热红伤寒，黄主脾病黑中恶，青主惊风白是疳，
风关病轻气关重，命关若见病多难，大小曲紫伤滞热，曲青人惊走兽占，
赤色水火飞禹扑，黄色雷惊黑阴痫，长珠伤食流珠热，去蛇吐泻来蛇疳，
弓里感冒外痰热，左斜伤风右斜寒，针形枪形生痰热，射指射甲命难全，
纹见乙字为抽搐，二曲如□伤冷传，三曲如虫伤硬物，水纹咳嗽吐泻环，
积滞曲虫惊鱼骨，形似乱虫有蛔缠，脉纹形色如参合，医者留神仔细观。

其纹色红黄相兼，隐隐不见，则为平安无病，
若纹色紫属内热，红属伤寒，黄为伤脾，黑为中恶，青主惊风，白主疳证，
纹在风关主病轻，气关主病重，若过命关主病危难治，
又当视其纹形大小曲弯，
色紫者主伤食内热，色青者主人惊及走兽惊，色赤者主水火飞禽所惊，
黄主雷惊，黑主阴痫，
如指上纹形一点红色，名曰流珠纹，主内热，
圆长者名曰长珠形，主饮食伤，
上尖长下微大者，名日去蛇形，主伤食吐泻，
上大下尖长者，名日来蛇形，主湿热成疳，
弓反里者，形弯向中指，主感冒寒邪，
弓反外者，形弯向大指，主内热痰盛，
纹斜向左者，其纹斜向中指，主伤风，
纹斜向右者其纹斜向大指，主感寒，
针形者，直若悬针微短，
枪形者，直射如枪微长，皆主痰热透，
关射指射甲者，其纹直射指甲指端，主脾气大败，病危不起，
二者俱属不治，
乙字纹似乙字，主惊风抽搐，
二曲如□，主伤生冷，
三曲如虫，主伤硬物，
水纹形似水字，主咳嗽，
环形联系如环，主疳病，
曲虫纹如弯虫，主积滞鱼骨，
纹如鱼刺，主惊热，
纹形如乱虫者，主蛔虫缠扰，
习幼科者，必以此形色合参，留衶诊察，始不误矣。

When examining the pulse pattern on the tiger's mouth (the web between the thumb and index finger) of a newborn infant, observe the left hand for males and the right hand for females. The three segments of the index finger are named Feng Guan (Wind Gate), Qi Guan (Qi Gate), and Ming Guan (Life Gate). If the pulse pattern is faintly visible and stable, it indicates health.
If morphological changes and color variations appear, disease can be diagnosed. Purple indicates internal heat; red indicates cold damage (Shang Han); yellow indicates spleen disease; black indicates Zhong E (acute severe condition); green indicates fright wind (Jing Feng); white indicates Gan syndrome (malnutrition/parasitic accumulation).
Disease indicated at Feng Guan is mild; at Qi Guan, it is severe; if reaching Ming Guan, the prognosis is often poor.
The size and curvature of the pulse pattern, along with purple coloration, indicate food stagnation and internal heat. Curvature with green coloration indicates fright caused by humans or beasts.
Red coloration indicates fright from fire, water, or flying creatures; yellow indicates fright from thunder; black indicates Yin epilepsy (a type of epilepsy).
A pattern resembling a long bead indicates food injury; one resembling flowing beads indicates internal heat.
Qu-She shape (tapered top, thick bottom) indicates vomiting and diarrhea; Lai-She shape (thick top, tapered bottom) indicates Gan syndrome.
Gong Fan Li shape (curved towards the middle finger) indicates cold pathogen invasion due to exogenous contraction; Gong Fan Wai shape (curved towards the thumb) indicates phlegm-heat excess.
Slanting to the left indicates wind injury; slanting to the right indicates cold invasion.
Zhen Xing (needle shape) and Qiang Xing (spear shape) indicate the generation of phlegm-heat.
Patterns extending to the fingertip (She Zhi) or fingernail (She Jia) indicate critical illness with poor prognosis.
A pattern resembling the character "Yi" (乙) indicates convulsions due to fright wind.
Two curves resembling a square indicate transmission of cold pathogen from cold food injury.
Three curves resembling an insect indicate injury from hard objects.
Water-like patterns indicate cough and vomiting/diarrhea.
Ring-shaped patterns indicate stagnation.
Curved insect-like patterns indicate fright.
Fish-bone-like patterns indicate food stagnation.
Patterns resembling chaotic insects indicate roundworm infestation.
Physicians must comprehensively analyze both the form and color of the pulse patterns, observing carefully to avoid errors.
[Note]
For any newborn infant suffering from disease, one must observe the color and form of the pulse patterns at the tiger's mouth to determine the severity and prognosis of the illness.
For males, examine the medial side of the index finger on the left hand first; for females, examine the medial side of the index finger on the right hand first.
The three segments of the finger are: the first segment is Feng Guan (Wind Gate), the second is Qi Guan (Qi Gate), and the third is Ming Guan (Life Gate).
If the pattern color is a mix of red and yellow and is faintly invisible, it signifies peace and absence of disease.
If the pattern color is purple, it belongs to internal heat; red belongs to cold damage; yellow indicates spleen injury; black indicates Zhong E; green indicates fright wind; white indicates Gan syndrome.
Patterns at Feng Guan indicate mild disease; at Qi Guan, severe disease; if passing through to Ming Guan, the disease is critical and difficult to treat.
One must also observe the thickness and curvature of the patterns.
Purple color indicates food injury and internal heat; green color indicates fright from humans or beasts; red color indicates fright from fire, water, or birds.
Yellow indicates fright from thunder; black indicates Yin epilepsy.
If the pattern on the finger appears as a single red dot, it is called Liu Zhu Wen (Flowing Bead Pattern), indicating internal heat.
If round and long, it is called Chang Zhu Xing (Long Bead Shape), indicating dietary injury.
If pointed and long at the top and slightly large at the bottom, it is called Qu She Xing (Departing Snake Shape), indicating food injury with vomiting and diarrhea.
If large at the top and pointed and long at the bottom, it is called Lai She Xing (Arriving Snake Shape), indicating damp-heat transforming into Gan syndrome.
Gong Fan Li (Bow bending inward) refers to the shape curving towards the middle finger, indicating cold pathogen invasion due to exogenous contraction.
Gong Fan Wai (Bow bending outward) refers to the shape curving towards the thumb, indicating internal heat and abundant phlegm.
Patterns slanting to the left point towards the middle finger, indicating wind injury.
Patterns slanting to the right point towards the thumb, indicating cold invasion.
Zhen Xing (Needle Shape) is straight like a hanging needle and slightly short.
Qiang Xing (Spear Shape) extends straight like a spear and is slightly long; both indicate the emergence of phlegm-heat.
Patterns extending to the finger tip (She Zhi) or nail (She Jia) extend directly to the nail or fingertip, indicating severe depletion of Spleen Qi and critical illness that may not recover.
Both are considered untreatable.
Yi Zi Wen (Character Yi Pattern) resembles the character "Yi", indicating fright wind and convulsions.
Two curves resembling a square indicate injury from cold raw foods.
Three curves resembling an insect indicate injury from hard objects.
Water Wen (Water Pattern) resembles the character "Shui" (water), indicating cough.
Huan Xing (Ring Shape) connects in a circle, indicating Gan disease.
Qu Chong Wen (Curved Insect Pattern) resembles a curved insect, indicating food stagnation or fish bone impaction.
Patterns resembling fish spines indicate fright-heat.
Patterns resembling chaotic insects indicate roundworm entanglement.
Practitioners of pediatrics must combine these forms and colors for comprehensive analysis and pay close attention during diagnosis to avoid mistakes.
