五指稍头冷，惊来不可当。
若逢中指热，必定是伤寒。
中指独自冷，麻痘证相参。
男左女右手，分明仔细看。
小儿三岁以上，医用中指滚转，按寸、关、尺三部，六、七至为常脉。增则为热，减则为寒
。浮，风邪；洪，热盛；数，多惊；迟，为虚；浮洪为风热；沉实为食积。浮紧无汗为伤寒；浮
缓有汗为伤风。沉紧，腹痛；弦紧，气急；紧促，痘疹；坚实，风痫；虚软；慢惊；软细，疳虫
；牢实，便秘；大芤，便血；大小不匀，恶候。二、三至为脱绝，十余至为死脉。
背暖∶经曰∶背脊三椎下节之两傍，是肺之俞也。若风寒伤之，致发热咳嗽，痰喘、呕等证。
肚暖∶肚者，胃也。若冷则不能腐化谷食，致肠鸣、腹痛、泄泻等证。
足暖∶经曰∶足为阳明胃经所司，况寒从地起。致伤寒发热、冷积等证。
头凉∶经曰∶头者，六阳之会；首面者，五脏之精华。头为髓之海，太热则髓溢汗泄，致颅囟
肿起，头疮眼疾。
心胸凉∶心属丙火，若外受客热，内外俱热。轻则口干面红；重则夜啼、惊跳。
精神未全∶忽见非常之物、未识之人、鸡犬牛马等畜，及嬉戏叫喊，皆易成惊疾。宜服镇心
安神、补养之药，病愈药止。其牛黄、朱砂、金银、冰、麝，毋得过用，致成冷疾。
吐泻慢惊；脾胃全固，气血流畅，一身康健。小儿变蒸，误作外邪，服发汗药；或因食积，
过用通泄；或冷热不调，致伤脾胃，吐泻淹延。脾土既虚，肝木乘之，故筋挛作搐。
呕乳粪清∶儿在胎时，母过取凉，冷气入于胞胎。后因悲啼未定，便与乳食，使气与食结，
久而不散，致伤脾胃。轻则呕泄，重则腹鸣气逆，涎潮流溢，以致难治。
勿轻服镇坠诸药∶水银、轻粉、朱砂、珠珀，虽云下痰镇心，毋得泛常轻用。凡小儿皆畏服
药。倘病源究未真确，药不切中，勿服。
因浴致生丹毒∶一周之内，肌肤脆嫩，腠理不密，洗之恐湿热郁蒸，变生赤游丹毒。身发壮
热，毒入腹者死。有因浴，伤风咳嗽上气，渐成笃疾，由此而始焉。
Cold at the tips of the five fingers indicates *Jing Feng* (Wind-Convulsion), which is difficult to withstand.
If the middle finger is hot, it is definitely *Shang Han* (Cold Damage).
If only the middle finger is cold alone, one must refer to the syndromes of *Ma Dou* (Smallpox and Measles) for reference.
Observe the left hand for males and the right hand for females clearly and carefully.
For children over three years old, the physician uses the middle finger to roll and press at the *Cun*, *Guan*, and *Chi* pulse positions, examining the three sections. Six or seven beats per respiration is the normal pulse. An increase in beats indicates Heat; a decrease indicates Cold.
Floating (*Fu*) pulse indicates Wind pathogen; Surging (*Hong*) pulse indicates Excess Heat; Rapid (*Shu*) pulse indicates frequent fright; Slow (*Chi*) pulse indicates Deficiency; Floating and Surging indicate Wind-Heat; Deep and Solid indicate Food Stagnation.
Floating and Tight with no sweat indicates *Shang Han*; Floating and Relaxed with sweat indicates *Shang Feng* (Wind Strike).
Deep and Tight indicates abdominal pain; Wiry and Tight indicates rapid breathing; Tight and Urgent indicates *Dou Zhen* (Pox/Rash); Firm and Solid indicates Wind Epilepsy; Empty and Soft indicates Slow Convulsion; Soft and Fine indicates *Gan Chong* (Malnutrition due to parasites); Deep, Firm and Solid indicates constipation; Large and Hollow indicates blood in stool; Unequal pulse size is an ominous sign. Two or three beats per respiration indicates collapse of vital energy; ten-plus beats indicates a death pulse.
Keep the back warm: The classics state that on both sides below the third thoracic vertebra are the *Fei Shu* (Lung Shu acupoints). If Wind-Cold damages this area, it causes fever, cough, phlegm-wheezing, vomiting, etc.
Keep the abdomen warm: The abdomen is the Stomach. If cold, it cannot rot and ripen grain and food, leading to borborygmus, abdominal pain, diarrhea, etc.
Keep the feet warm: The classics state that the feet are governed by the Yangming Stomach Meridian, moreover, cold rises from the ground. This leads to *Shang Han* fever, cold accumulation, etc.
Keep the head cool: The classics state that the head is the convergence of the six Yang meridians; the head and face are the essence of the five zang organs. The head is the sea of marrow; if too hot, marrow overflows and sweat leaks, causing swelling of the cranial fontanelle, head sores, and eye diseases.
Keep the heart and chest cool: The Heart belongs to Bing Fire. If externally affected by guest heat, both interior and exterior become hot. Mild cases cause dry mouth and red face; severe cases cause night crying and startle/jumping.
Spirit not fully formed: Suddenly seeing unusual objects, unfamiliar people, animals like chickens, dogs, cattle, horses, or playing and shouting can easily lead to Fright disorders. It is suitable to take medicines that calm the heart and spirit and nourish the body. Stop medication when the illness resolves. Do not overuse Niuhuang (Calculus Bovis), Zhusha (Cinnabar), Jin Yin (Gold/Silver), Bingpian (Borneol), and Shexiang (Musk), lest they cause Cold disorders.
Vomiting, diarrhea, and slow convulsion: When the Spleen and Stomach are solid, Qi and Blood flow smoothly, and the body is healthy. In infants' *Bian Zheng* (physiological growth changes), if mistakenly treated as external pathogens and given diaphoretic medicines; or due to food stagnation, overusing purgatives; or due to imbalance of cold and heat damaging the Spleen and Stomach, causing prolonged vomiting and diarrhea. Once the Spleen Earth is deficient, Liver Wood overacts upon it, resulting in tendon spasms and convulsions.
Vomiting milk and clear feces: During gestation, if the mother excessively seeks coolness, cold qi enters the fetal sac. Later, if milk and food are given while the infant is still unsettled from crying, Qi and food knot together and do not disperse for a long time, damaging the Spleen and Stomach. Mild cases cause vomiting and diarrhea; severe cases cause borborygmus, rebellious Qi, overflowing saliva, making it difficult to treat.
Do not lightly administer sedative/heavy-settling medicines: Shuiyin (Mercurius), Qingfen (Calomel), Zhusha (Cinnabar), Zhu Po (Pearl and Amber), although said to resolve phlegm and settle the heart, should not be used casually. All children fear taking medicine. If the disease source is not thoroughly investigated and accurate, and the medicine does not hit the pathology accurately, do not administer it.
Dan Du caused by bathing: Within the first week, the skin and muscles are fragile and tender, and the interstices (*Cou Li*) are not dense. Washing may cause damp-heat to stagnate and steam, transforming into Chi You Dan Du (Red Roaming Erysipelas). Severe fever appears on the body; if the toxin enters the abdomen, death occurs. Some, due to bathing, catch wind leading to cough and rebellious Qi, gradually becoming critically ill, starting from here.
