[Verse] Yellow and cyan patterns indicate wind-stroke due to fright; red indicates cold damage; purple or pale red also relates to cold damage. Black signifies pain, while white indicates deficiency-cold cough. Further divine skill is required by referring to the specific section where the pattern appears.

[Discussion] Observe the area at the junction of the thumb and index finger on either hand of the child, known as the "Tiger's Mouth" (Hu Kou). Extending from the Tiger's Mouth towards the finger, the first segment is named the "Wind Gate" (Feng Guan), the second segment the "Qi Gate" (Qi Guan), and the third segment the "Life Gate" (Ming Guan).

If the pattern is visible only at the Wind Gate, it is easy to treat; if it extends through the Qi Gate, it becomes gradually more difficult; if it penetrates all three gates, death is likely. Observing the left-hand pattern, the disease corresponds to the Heart and Liver; observing the right-hand pattern, the disease corresponds to the Spleen and Lungs.

There are five colors of patterns: Purple indicates wind pathogen in the exterior; fright causes a cyan pattern; pale red indicates cold-heat in the exterior; deep red inevitably leads to cold damage or smallpox/variol; cyan and red mixed indicate fright-heat. A chaotic pattern indicates a long-standing disease; a thin pattern indicates abdominal pain with frequent crying and indigestion of milk/food; a thick pattern straight towards the nail indicates severe wind-stroke due to fright; a black pattern like ink generally indicates a critical condition that is difficult to treat.

[Verse] For pediatric diseases, pulse diagnosis is essential; one finger covers the three gates to determine the respiration/pulse rate. Floating pulse indicates wind-heat; rapid pulse indicates fright; deficient and slow pulses indicate deficiency-cold; excess pulse indicates accumulation/stagnation.

[Discussion] The floating pulse indicates wind pathogen. In autumn, it is considered a normal pulse (Ping); in other seasons, it indicates injury by wind-cold, manifesting as headache, high fever, or night fever with daytime coolness, coughing, sneezing, nasal congestion with clear discharge, vomiting/regurgitation, and anorexia.

The surging pulse indicates heat. In summer, it is considered a normal pulse; in other seasons, it indicates abundant wind-heat, manifesting as warm-to-hot body temperature, fright, sores/ulcers, and bloody diarrhea.

The rapid pulse indicates fright. In spring, it is considered a normal pulse; in other seasons, it indicates wind-stroke with convulsions. A small rapid pulse often presents with excessive sleep, startle/jumping, staring straight ahead, fearfulness, night sweats, teeth grinding in dreams, tongue protrusion, wheezing, and vomiting. A large rapid pulse will inevitably lead to convulsions within one or two days.

Deep and slow pulses indicate deficiency-cold. Appearing in any season, they indicate Spleen-Stomach weakness, manifesting as slippery diarrhea with rectal prolapse, continuous vomiting and dysentery, gradual emaciation leading to Spleen exhaustion, or developing into infantile malnutrition (Gan) and consumption.

The excess pulse indicates stagnation/accumulation. In winter, it is considered a normal pulse; in other seasons, it indicates food injury, accumulation, abdominal distension, or pain. With hair standing on end, vomiting, and diarrhea, if treated slowly, it may develop into severe conditions such as Gan malnutrition, Ding Xi (severe emaciation with prominent abdomen), or Bu Lu (failure to thrive with sunken eyes), requiring supplementation after removing the accumulation.
