When examining a child's pulse, one should use the thumb to press the three positions (Cun, Guan, Chi). Six to seven beats per respiration cycle indicate a harmonious pulse. Ten beats per cycle indicate fever; five beats per cycle indicate internal cold. (Another version suggests abdominal distension.) A tight pulse indicates wind-phlegm epilepsy (Feng Xian); a deep and slow pulse indicates food stagnation; a rapid and hurried pulse indicates deficiency fright; a wiry and tense pulse indicates disharmony of Qi; a deep and thin pulse indicates cold; a floating pulse indicates wind; an irregular pulse in size indicates a malignant prognosis or supernatural affliction; a floating, large, and rapid pulse indicates wind-heat; a hidden and knotted pulse indicates accumulation of pathogenic factors; a single thin pulse indicates malnutrition consumption (Gan Lao) with abdominal pain, often accompanied by wheezing and vomiting. A surging pulse indicates the presence of parasites; a deep (another version says floating) and slow pulse with tidal fever indicates stomach cold, which can be cured by warming. I once composed a song to record this: "Child's tight pulse signals wind-phlegm epilepsy, deep and slow indicates food stagnation with much vomiting, wiry and tense reveals Qi disharmony, rapid and hurried shows deficiency fright where spirit does not reside, cold presents as deep and thin, wind as floating, firm and solid stool should be constipated for long, after abdominal pain if pulse is tight and wiry, chaotic pulse is beyond salvation. During the period of transformation and evaporation (Bian Zheng), the pulse must change, untreated it naturally causes no error, single thin indicates malnutrition consumption, surging indicates parasites, irregular size indicates malignant prognosis, deep (another version floating) and slow with tidal fever, this must be stomach cold invading internally, (internally another version says acts as) diarrhea with floating and large pulse is incurable, carefully ponder and investigate." For infants who cannot yet have their pulse taken, folk doctors often examine the color of the veins at the Tiger's Mouth (Hukou) and the temperature of the four limbs, which also has its merits. I further composed two songs to record this. Song on Tiger's Mouth Color: "Purple indicates heat, red indicates wind-cold (Shang Han), green indicates fright, white indicates malnutrition, black indicates sudden evil invasion, yellow indicates spleen distress." Song on Cold and Heat Syndromes: "Cold nose definitely indicates pox/rash, (another version says smallpox) cold ears should indicate wind-heat syndrome, whole body hot indicates wind-cold, upper hot lower cold indicates food stagnation." If one can combine color and pulse for verification, the results obtained will be more than half correct.

When the rash is about to erupt, it is appropriate to resolve the muscle layer to support its emergence; sweating is contraindicated, as sweating weakens Qi and causes sinking. It is appropriate to harmonize the interior to relieve congestion; purgation is contraindicated, as purgation causes the toxin to re-enter the interior. It is appropriate to transform the toxin to nourish Yin; cold-natured suppression is contraindicated, as cold suppression causes the toxin to close and fail to emerge. This is a common error, which students must not ignore.
