When a child reaches one year of age, the *bianzheng* (physiological febrile phenomena associated with infant growth and development) is complete. At this point, the pulse begins to manifest at the *Cunkou* (radial artery at the wrist). I have observed that in infants less than one month old, there is also a pulse sensation near the high bone of the palm (styloid process of the radius), moving slightly with each breath. The pulse is the ripple of Qi and Blood. Since they are born as humans, they must possess Qi and Blood; how could they lack a pulse? It is merely that adults do not exert the utmost effort to investigate its origins meticulously.

For pediatric diseases, diagnosis must rely on the pulse. Using one finger across the three positions (Cun, Guan, Chi) determines the pulse rate. A slow (*Chi*) pulse indicates cold, and a rapid (*Shu*) pulse indicates heat, a principle passed down through ancient and modern times. A floating (*Fu*) pulse indicates wind, and a deep (*Chen*) pulse indicates accumulation; these should be recognized first. The left hand's *Renying* position (referring to the left radial pulse, representing exterior/exterior syndromes) primarily governs external conditions. The right hand's *Qikou* position (referring to the right radial pulse, representing interior/interior syndromes) primarily governs internal diseases. External observations monitor invasions by wind, cold, summer-heat, and dampness. Internal observations monitor lesions caused by milk/food retention and phlegm accumulation. A full, large, and tight pulse without sweating indicates *Shanghan* (Cold Damage). A floating and relaxed pulse with spontaneous sweating indicates *Shangfeng* (Wind Strike). A floating and full pulse often indicates excess wind-heat. A deep and thin pulse is due to food stagnation. A deep and tight pulse indicates unceasing abdominal pain. A wiry and tight pulse indicates airway urgency. During periods of tightness and urgency, smallpox/rash emerges. During periods of tightness and rapidity, *Jingfeng* (pediatric convulsions) arrives. A deficient and soft pulse indicates slow *Jingfeng* with twitching. A tight and solid pulse indicates wind-*Xian* (epilepsy) with convulsions. A soft and thin pulse indicates *Ganchong* (worm infestation or malnutrition). A firm and solid pulse is due to constipation. A hollow (*Kou*) pulse indicates blood in stool or urine. A deficient and soggy pulse indicates Qi deficiency combined with palpitations and fright. A slippery (*Hua*) pulse indicates injury from exposure to dew, cold, and dampness. A wiry and urgent pulse indicates *Kewu* (sudden fright or pathogenic invasion); you must remember this. Irregular pulse size is an ominous sign. Two beats per respiration indicates collapse (*Tuo*); three beats indicates sudden death. Five beats indicates deficiency (*Xu*); four beats indicates damage (*Sun*). Six beats per respiration is harmonious, indicating no disease. Seven to eight beats indicate mild illness. Nine to ten beats indicate critical illness. Eleven to twelve beats indicate certain death. This formula is infallible.

Heart Pulse: A floating and rapid heart pulse indicates fright and heat. Heatstroke causing irritability and crying is clearly diagnosed by this rule. It also relates to intestinal hernia, coiled intestine (intestinal colic), congestion, mouth ulcers, and scanty/difficult urination. A deep and slow heart pulse indicates cold in the Zang-Fu organs. Various Qi disorders accompanied by cold cause unbearable pain. Frequent urination and cold intestines require careful examination under the fingers.

Liver Pulse: A floating and rapid liver pulse definitively indicates wind. Red eyes with nebulae also indicate tendon issues. Tearing, bleeding, and eye discharge indicate either itching or pain with photophobia. A deep and slow liver pulse indicates cold. A blueish complexion, white lips, and a preference for opening the mouth suggest that various diseases have progressed to slow wind syndrome (chronic convulsions). Physicians must analyze this carefully.

Spleen Pulse: A floating and rapid spleen pulse indicates hot phlegm and saliva. The patient may eat well but reject stomach functions while the spleen is firm. Drooling (*Zhiyi*), mouth ulcers, and stagnation/congestion occur. Red lips and face indicate stomach heat. A deep and slow spleen pulse indicates wind invasion. With vomiting and diarrhea, it progresses to slow spleen wind (chronic spleen deficiency). Qi deficiency and weak stomach prevent eating. For drooling and vomiting, use *Xingpi Wan* (Spleen-Awakening Pill).

Lung Pulse: A floating and rapid lung pulse indicates hematochezia. Cold damage with cough and generalized fever, airway urgency, severe phlegm, or rashes. Diarrhea, dysentery, tidal fever, and large bowel obstruction. A deep and slow lung pulse indicates deficiency-cold. Spleen and stomach slipping/intestine or profuse diarrhea. Cough and phlegm persist. If the root is unstable, the pulse lacks foundation.

Kidney Pulse: A floating and rapid kidney pulse indicates real heat. Hernia (testicular swelling/drooping), bladder pain, and redness. Bad breath and teeth grinding indicate kidney fright. Fire-heat causes fresh blood from inside the gums. A deep and slow kidney pulse definitively indicates cold. Pathogens lingering in Zang-Fu enter the scrotum. Hernia and bladder pain may be absent. A floating and deficient-large pulse is the most difficult to treat.
