为医先要去贪嗔，用药但凭真实心；富不过求贫不倦，神明所在俨如临。
人有恒心，践履端谨，始可与言医道矣。凡有请召，不以昼夜寒暑远近亲疏，富贵贫
贱，闻命即赴，视彼之疾，举切吾身，药必用真，财无过望，推诚拯救，勿惮其劳，冥
之中，自有神佑。如临汝张彦明为医，未尝以钱为较，应有求医，期于必效。一日城中
火灾，周回 尽，烟焰中独存其居，后且子孙荣贵。以此见天道有阴扶显助之灵，诚为可敬。
色脉参详贵造微，早凭疾证决安危；时医怕触病家讳，病稍差池便怨咨。
为医固难，及幼尤难。故医者诊视小儿之证，倘色脉精明，则死生可判。若以恐触
病家之讳，犹豫其说，不吐真情，稍有差池，必招其怨。与其受怨于后，孰若告之于先。纵
有危难，夫复何怨。昔扁鹊见桓侯曰∶疾在腠理，不治将深。恒侯不信。复见曰∶疾在
骨髓，虽司命无如之何。后果弗起。学人于此，触类究心，斯有得于扁鹊之妙旨。
积黄青则是惊风，热赤伤寒紫淡红；黑痛白为虚冷嗽，更须随部用神工。
望闻问切，医者先之。凡看病形指文，听声察色，其病图载方册，皮有薄浓，但周时
外婴孩，多在怀抱，手无垢腻，则指白皮嫩，其纹显而易见。至三五岁者，常贪戏耍，手
弄泥水，则指粗皮浓，其纹隐而难辨。参诸面部，是为捷要。有紫黑而纹粗，或叫怒而

饱曰讥，痒曰痛，如是类者，屡尝试之。每究心及此．初在父母审其得患之由，而告医
者参详，则易于调治。多有病家不肯自言其致疾之始末，而一听医者之揣摩。由是观之，
问亦难矣，必须诊脉以决诸证。然南北禀赋不同，施治之法亦当随其虚实冷热用药可也。
若夫造妙工夫，初无其他，大学所谓若保赤子，心诚求之。专是业者，倘不尽此心之诚，
何以察不言之疾乎？
行医首先要去除贪婪和嗔怒，用药只凭一颗真实诚恳的心；不因为患者富有就有所求，也不因为患者贫穷就懈怠，对待病人要像神明亲临一样庄重严肃。
人只要有恒心，行为端正谨慎，才可以与他谈论医道。凡是有人请诊，不分昼夜、寒暑、远近、亲疏、富贵或贫贱，听到召唤立即前往，看待病人的疾病，就像看自己的病一样切身感受，用药必须纯正真实，对钱财不要有过分期望，以诚心去拯救病人，不要害怕劳累，在冥冥之中自然会有神灵保佑。比如汝州人张彦明行医，从未计较金钱，所有来求医的人，都致力于确保疗效。有一天城中发生火灾，周围房屋烧尽，唯独他的住所因烟焰中幸存下来，后来他的子孙也显赫尊贵。由此可以看出天道有暗中扶持、显性帮助的神灵，确实值得尊敬。
面色与脉象参详贵在探究细微之处，尽早凭借疾病症状判断安危；庸医害怕触犯病家的忌讳，病情稍有变化便抱怨指责。
做医生固然困难，诊治小儿更是难上加难。所以医生诊断小儿病症时，如果面色和脉象精明清晰，就能判断生死。如果因为害怕触犯病家的忌讳，犹豫不决，不吐露真情，稍有差错，必然会招致怨恨。与其事后受怨，不如事先告知。纵然出现危难，又有什么可怨恨的呢？从前扁鹊见蔡桓侯说：“病在皮肤纹理之间，不治将会深入。”蔡桓侯不信。再次见到时说：“病在骨髓，即使掌管生命的神也无法救治了。”后来蔡桓侯果然病重不起。学习医学的人对此应触类旁通，用心钻研，这样才能领悟扁鹊的奥妙宗旨。
面色发黄发青则是惊风，发热面赤是伤寒，紫色淡红也是伤寒表现；黑色主痛，白色主虚冷咳嗽，还必须根据面部不同部位运用高超医术。
望、闻、问、切是医生首先应该掌握的。凡看病形、指纹，听声音、察面色，这些病症图谱记载在医书中，皮肤有厚薄之分，但周岁以内的婴儿多在怀抱中，手没有污垢油腻，则手指白嫩，指纹显而易见。到三四岁的孩子，常贪玩弄泥水，则手指粗糙皮厚，指纹隐蔽难以辨别。参考面部神色，这是简便关键的方法。如果有紫黑色且指纹粗大，或者哭闹愤怒而容貌改变，则仓促间难以确定，必须听声音判断。如果有中风导致的昏迷闷乱，或者久病导致的昏沉，说话迟缓失音，口疮咽痛，尤其不是仅靠听声音就能完全知晓的。“问证”这一环节最为确切得当。然而儿科脉学被称为“哑科”，即使稍长些的孩子说的话也不足全信，有的把饱胀说成讥讽（可能是误译，原文“曰讥”语境较晦涩，通常指表达不清或胡言），把瘙痒说成疼痛，像这样的情况，需要多次尝试询问。每当用心思考于此，起初要在父母那里审问清楚患病的原因，然后告诉医生供其参详，这样就易于调治。有很多病家不肯自己说出致病始末，而只听任医生揣摩推测。由此看来，问诊也很难，必须通过诊脉来决断各种病症。然而南北方人体质禀赋不同，施治方法也应当根据虚实冷热来用药。至于达到精妙的功夫，起初没有其他诀窍，正如《大学》所说“如同保护婴儿一样，心诚地去寻求”。专门从事这一行业的人，如果不竭尽这颗心的真诚，又怎么能察觉那些无法言语的疾病呢？
To practice medicine, one must first eliminate greed and anger, relying solely on a sincere and authentic heart when prescribing medication; one should not seek profit from the wealthy nor show fatigue towards the poor, treating patients with solemnity as if deities were present.
Only when a person possesses perseverance and conducts themselves with uprightness and caution can they be taught the Way of Medicine. Whenever summoned for consultation, regardless of day or night, cold or heat, distance, closeness, wealth, or poverty, one should respond immediately upon hearing the call. One should regard the patient's illness as one's own, use genuine and pure medicines, have no excessive expectation of financial gain, save patients with sincerity, and not fear labor. In the unseen realm, there will naturally be divine protection. For instance, Zhang Yanming from Ruzhou practiced medicine without ever calculating money. For all who sought medical help, he aimed for certain efficacy. One day, a fire broke out in the city, burning down surrounding houses, yet his residence remained standing amidst the smoke and flames. Later, his descendants became prominent and noble. From this, we can see that the Heavenly Dao has spirits that secretly support and visibly assist, which is truly worthy of reverence.
Analyzing facial color and pulse requires attention to subtle details; early judgment of safety and danger based on disease symptoms is crucial. Quack doctors fear offending their patients' taboos, and when the condition slightly worsens, they complain and blame.
Practicing medicine is indeed difficult, but diagnosing children is even more so. Therefore, when a physician examines pediatric cases, if the facial complexion and pulse are clear and distinct, life and death can be determined. If one hesitates due to fear of offending the family's sensitivities and does not speak the truth, any slight error will inevitably invite resentment. It is better to warn beforehand than to suffer resentment afterwards. Even if difficulties arise, what is there to resent? In the past, Bian Que saw Duke Huan of Cai and said, "The disease is in the skin and muscles; if untreated, it will deepen." The Duke did not believe him. Upon seeing him again, Bian Que said, "The disease is in the bone marrow; even the Lord of Life cannot do anything about it." Eventually, the Duke fell seriously ill and could not recover. Students of medicine should reflect on this case, drawing parallels and studying diligently, thereby grasping the profound principles of Bian Que.
Yellowish or bluish complexion indicates convulsive wind (Jing Feng); redness with heat indicates Cold Damage (Shang Han); purple or pale red also relates to Cold Damage; black indicates pain; white indicates deficiency-cold and cough. One must further apply skilled techniques according to different facial areas.
Inspection, auscultation/olfaction, inquiry, and palpation are the primary methods for physicians. When examining physical forms and finger veins, listening to sounds, and observing colors, these conditions are recorded in medical texts. Skin thickness varies. Infants under one year old are mostly carried in arms; their hands are free of dirt and grease, making fingers white and tender, with finger veins clearly visible. Children aged three to five often play with mud and water, making fingers rough and thick-skinned, with hidden and hard-to-distinguish veins. Observing the facial complexion is a key shortcut. If the complexion is purple-black with coarse veins, or if the child cries angrily with altered expression, diagnosis is difficult in haste, requiring auditory assessment. Conditions such as stroke-induced coma, chronic lethargy, delayed speech, aphonia, mouth ulcers, and sore throat cannot be fully understood by hearing alone. Inquiry into symptoms is the most accurate method. However, pediatrics is known as the "Mute Department" because even older children's statements may not be reliable; some confuse fullness with other sensations, or itching with pain. Such instances require repeated attempts at questioning. Initially, parents should clarify the cause of illness to inform the doctor for analysis, facilitating treatment. Many families refuse to disclose the onset and course of the disease, leaving it to the doctor's speculation. Thus, inquiry is difficult, and pulse diagnosis is necessary to confirm symptoms. Since constitutions differ between North and South, treatment methods should be adjusted according to deficiency/excess and cold/heat. As for achieving mastery, there is no other secret than what the *Great Learning* states: "As if protecting an infant, seeking it with a sincere heart." Those dedicated to this profession must not lack sincerity in their hearts; otherwise, how can they perceive diseases that cannot be verbally expressed?
