【注】小儿之病，既观其色，又当细听其声。盖笑、呼、歌、悲、呻五声，内应心、肝、

金病，则声悲音浊；肝属木病，则声狂叫多呼；脾属土病，则声颤轻如歌；肾属水病，则

腹痛；哭而不啼，则气急心烦，将成惊也。 煎不安者，乃心经内热，故烦躁不宁也。嘎
声，音哑也。声重，声浊也。此为外感风寒也。有余之证其气实，故声雄大而壮厉；不

身凉皆阴也，阴主脏，故曰阴脏证也。狂言焦躁者，邪热盛也；神昏谚语者，热乘于心，

The method of diagnosing pediatric diseases lies in listening to the five sounds. By hearing the sounds and analyzing their principles, one can clearly understand the condition. The five sounds correspond to diseases of the five Zang organs; disharmony of the five sounds reflects the pathological state of the five Zang organs. In Heart disease (Xin Bing), the voice is urgent with much talking and laughing; in Lung disease (Fei Bing), the voice is sorrowful and the tone is unclear; in Liver disease (Gan Bing), the voice involves calling out with much wild shouting; in Spleen disease (Pi Bing), the voice resembles singing with a trembling and light tone; in Kidney disease (Shen Bing), the voice is groaning, long, and thin. When the five tones are distinct, the syndromes are clear. Crying without tears indicates abdominal pain; weeping with tears but short or silent voice suggests impending convulsions (Jing Feng). Restlessness and internal heat cause discomfort; hoarseness with a heavy tone indicates contraction of Wind-Cold (Feng Han). A robust and vigorous voice often indicates Excess (Shi) patterns, while a short, timid, and light voice often indicates Deficiency (Xu) patterns. Much talking accompanied by fever belongs to Yang Fu syndromes (Yang Organ Syndromes); reluctance to speak accompanied by cold body temperature belongs to Yin Zang syndromes (Yin Viscera Syndromes). Delirious speech with irritability indicates flourishing pathogenic Heat (Re); delirium with unconsciousness indicates a severe and ominous heat syndrome. A quack-like sound stuck in the throat with inability to vocalize is a critical sign; a straight, urgent voice without resonance and without tears indicates impending death. Deficiency and excess, Cold and Heat can be distinguished by the voice; upon hearing the voice, the condition is revealed without concealment.
[Note] For pediatric diseases, one must observe the complexion and carefully listen to the voice. The five sounds—laughing, calling, singing, grieving, and groaning—correspond internally to the Heart, Liver, Spleen, Lung, and Kidney. Disharmony of the five sounds indicates pathology in the five Zang organs. For instance, Heart disease associated with Fire presents with an urgent voice and a tendency to laugh; Lung disease associated with Metal presents with a sorrowful voice and turbid tone; Liver disease associated with Wood presents with wild shouting and frequent calling; Spleen disease associated with Earth presents with a trembling, light voice resembling singing; Kidney disease associated with Water presents with long, thin groaning. "Ku" (crying) has sound and tears with a long duration; "Ti" (whimpering) has sound but no tears with a short duration. If there is whimpering without crying, it indicates stagnant Qi, primarily abdominal pain. If there is crying without whimpering, it indicates rapid breathing and mental restlessness, suggesting impending convulsions. "Jian bu an" (restlessness/tossing about) refers to internal Heat in the Heart Meridian, causing irritability and agitation. "Ga sheng" refers to hoarseness. "Sheng zhong" refers to a turbid voice. These indicate external contraction of Wind-Cold. In Excess syndromes, Qi is solid, resulting in a loud, grand, and fierce voice; in Deficiency syndromes, Qi is weak, resulting in a timid, weak, and short voice. Much talking and fever are Yang attributes; Yang governs the Fu organs, hence "Yang Fu Syndrome." Reluctance to speak and coolness are Yin attributes; Yin governs the Zang organs, hence "Yin Zang Syndrome." Delirious speech and irritability indicate flourishing pathogenic Heat; delirium and unconsciousness indicate Heat invading the Heart, hence "ominous heat disease." "Ya sheng" (duck-like sound) is a hoarse sound stuck in the throat, indicating impending exhaustion of Qi; "Zhi sheng" (straight sound) is an urgent voice without resonance, indicating dispersion of Qi. Both are untreatable conditions. If physicians can observe thus, they will discern the interior and exterior, Zang and Fu, Cold and Heat, Deficiency and Excess, and the manifestations of all diseases will be fully revealed.
