小儿夜啼者，有因胎热伏心，阴则与阳相刑，热则与阳相合，夜则阳衰，阴乃与阳
相搏，脏气相击，故作痛而夜啼。其候面赤唇红，恍惚壮热，小便色赤。手足动摇，咂
口弄舌，憎热燥闷，重则胸突头反也。有因胎惊而啼者，其候必一啼。若绝，而面紫手
足阙冷，乍醒乍啼。然身体温凉大便青绿者，阴也。若身体发热，精神不清，睡中惊
啼，二便赤黄者，阳也。若身热而便青白，或身凉而便赤黄者，半阴半阳也。至若啼
时，口多涎沫，腰曲拘挛面青泻青者，寒痰内 也。若啼时多搐，手足张惶，紧抱父
母，四顾恐怖者，此必因视非常之物，及客忤耳。如若目有所睹而惊哭者，此必邪祟所
侵，其候虎口无纹，而色变易不常也。凡啼而不哭是痛，故直声来往而无泪。哭而不啼
是惊，故连声不绝而多泪也。

Infantile nocturnal crying may be caused by fetal heat latent in the Heart. Yin conflicts with Yang, and heat combines with Yang. At night, when Yang Qi declines, Yin contends with Yang, causing the Zang-Fu Qi to strike each other, resulting in pain and nocturnal crying. The manifestations include a red face, red lips, mental confusion, high fever, and dark red urine. There is trembling of the hands and feet, smacking of the lips, playing with the tongue, aversion to heat, restlessness, and stuffiness. In severe cases, there is protrusion of the chest and retraction of the head. Nocturnal crying due to fetal fright is characterized by paroxysmal crying. If it ceases, the face becomes purplish, and the hands and feet are cold; the infant alternates between waking and crying. If the body temperature is normal or cool and the stool is greenish, it indicates a Yin pattern. If the body is hot, the spirit is unclear, there is startled crying during sleep, and both urine and stool are reddish-yellow, it indicates a Yang pattern. If the body is hot but the stool is greenish-white, or if the body is cool but the urine and stool are reddish-yellow, it indicates a half-Yin, half-Yang pattern. If there is excessive salivation during crying, curvature and spasm of the waist, a bluish complexion, and greenish stool, it indicates internal obstruction by cold-phlegm. If there are frequent convulsions during crying, panic and agitation of the limbs, tight clinging to parents, and fearful looking around, this is certainly due to viewing unusual objects or invasion by "Ke Wu" (alien pathogenic factors). If crying and startling occur upon seeing something, it is certainly due to invasion by evil spirits, manifested by the disappearance of the fingerprint on the Tiger's Mouth area and irregular changes in complexion. Generally, crying without weeping indicates pain, hence the straight, intermittent sound without tears. Weeping without continuous crying indicates fright, hence the unceasing loud cries with abundant tears.
