The external manifestations of the five Zang organs are primarily reflected in specific areas of the face: the ears are the orifices of the Kidney (Shen), and the two eyes belong to the Liver (Gan). The nostrils are governed by the Lung (Fei), the lips by the Spleen (Pi), and the tip of the tongue by the Heart (Xin).

The left cheek corresponds to Wood and the Liver, which tends to generate Wind; the right cheek corresponds to Metal and the Lung. The forehead belongs to Fire and the Heart, while the chin (Di Ge) belongs to Water and the Kidney. The nose tip (Zhun Tou) belongs to Earth and is located centrally on the face.

The Liver governs Wind, manifesting as fixed staring of the eyes, mental restlessness, crying and shouting, and agitation. The Heart governs Heat, manifesting as insomnia, palpitations with fright, thirst, and dryness of the mouth and tongue. The Spleen governs stagnation and fatigue, manifesting as excessive sleepiness, vomiting and diarrhea, emaciation, and weakness, eventually leading to Gan syndrome (infantile malnutrition). The Lung governs Qi, manifesting as frequent coughing, dry skin, withered hair, and continuous wheezing. The Kidney governs Deficiency, manifesting as weak prenatal Qi; if a child's Kidneys are weak, nurturing them is difficult.

Currently, people specifically observe the fingerprint patterns on the tiger's mouth (the web between the thumb and index finger), dividing them into three sections: the Wind Section (Feng Guan), the Qi Section (Qi Guan), and the Life Section (Ming Guan). Disease at the Wind Section is mild, at the Qi Section is severe, and if it extends beyond the Life Section, death is imminent. Blue-green veins indicate cold or pain, red indicates heat, and black indicates a dire condition. A straight pattern suggests mild disease, while oblique or curved patterns suggest severity; cloud-like patterns require careful assessment.

In pediatric pulse diagnosis, one finger covers three positions. A normal rate is six beats per respiration. Seven to eight beats per respiration indicates rapidity and Heat. Three to four beats per respiration indicates slowness and Deficient Cold. A firm and harmonious pulse indicates health, while a fine, small, deep, and slow pulse indicates disease.

According to texts such as *Quan Ying Shu*: For children under three years old, if a Wiry Pulse (Xian Mai) appears at the Yin-Mao section on the first phalanx of the tiger's mouth, it can verify the pathological state. Observe the left hand for males and the right hand for females. If the pulse starts at the Yin section but does not reach the Mao section, the disease is easy to treat; if it connects to the Mao section, it is difficult to treat; if it connects from Yin to Mao and exceeds the Chen section, fewer than one in ten cases can be saved. If the pulse is wiry, small, or short, the disease is treatable. These findings should be cross-referenced with other diagnostic methods.

Crying with fixed staring indicates Heat in the Liver; administering Xie Qing San (Drain Liver Powder) promptly brings relief. Crying with a red face indicates Heat in the Heart; using Dao Chi San (Guide Out Red Powder) combined with Dong Gong (Ophiopogon Tuber) yields miraculous results. A red face accompanied by cold extremities and abdominal pain requires Yi Huang San (Benefit Yellow Powder) taken with ginger decoction. Nightly crying when seeing lights is often due to parental over-indulgence and unmet demands.

Acute Jing Feng (Convulsive Disorder) presents with a red face, hot back, fixed staring without eye movement, limb convulsions, and locked jaw. The patient may fall into a coma and never wake up.
Upon onset of Jing Feng, pinch the Renzhong point (GV26) and grasp the Zongjin tendon at the tiger's mouth. If accompanied by diarrhea, swallow Dao Chi San for regulation, employing cooling methods to calm Jing.
If there is facial paralysis (deviation of mouth and eyes), observe which side is affected. Apply cauterization to the acupoint below the Taiyang cheek area; one application brings natural peace.
A yellowish-white complexion with weak Shen Spirit, drowsiness, closed eyes, and an open mouth indicates Slow Jing Feng (Chronic Convulsive Disorder) with intermittent spasms. Cold breath from the nose and mouth and cold extremities confirm this diagnosis.
Slow Jing Feng is difficult to cure; urgently regulate Yuan Qi and tonify the Spleen. Gradual awakening and ability to eat are auspicious signs. Constant lethargy and refusal to nurse indicate critical danger.
