雷真君曰∶脉诀，《内经》已畅言矣，王叔和又发明之，予又何言。虽然尚有未备者，不可不一
论之。脉诀，大约言愈多则旨益晦，吾独尚简要以切脉，不必纷纷于七表八里也。切脉之最要者
在浮沉，其次则迟数，又其次则大小，又其次则虚实，又其次则涩滑而已。知此十脉，则九人之病
不能出其范围。至于死脉，尤易观也。不过鱼虾之游、禽鸟之喙、屋漏弹石、劈索水流之异也。知十
法之常，即可知六法之变，又何难知人之疾病哉。《灵枢》之形容脉象，不可为法也。
张真君曰∶脉诀原不必多，多则反晦。明言十法，至简至要，可以为万世切脉之法。
人有南北之分者，分于强弱也。南人之弱，不及北人之强也远甚。然而南人亦有强于北人
者，北人亦有弱于南人者，亦不可一概而论。然而统治强弱，又断断不可，当观人以治病，不可执南北
以治强弱也。盖天下有偏阴偏阳之分，偏于阳者，虽生于南而亦强；偏于阴者，虽生于北而亦
弱。故偏于阳者，宜用寒凉之剂；偏于阴者，宜用温热之品也。
张真君曰∶是。
雷真君曰∶病之有寒热也，半成于外来之邪，然亦有无邪而身发寒热者，不可不知。无邪而身
发寒热，乃肝气郁而不得宣，胆气亦随之而郁。木之气既郁滞，而心之气自然不舒，心肝胆三经
皆郁，则脾胃之气不化，肺金无养，其金不
刚，上少清肃之气下行，而木寡于畏，土且欲发泄而不能，于是作寒作热，似疟非疟、而不能止。倘
用祛邪之药，则其势更甚，惟有舒其木气，而寒热自除矣。
张真君曰∶亦创论也，方宜用逍遥散，大加白芍可也。
雷真君说：脉诀，《黄帝内经》中已经阐述得很详尽了，王叔和又进一步阐发发明它，我还有什么可说的呢。虽然如此，但仍有不完善的地方，不能不加以论述。关于脉诀，大概来说，谈论得越多，主旨就越晦涩难懂，我唯独崇尚简明扼要地切脉，不必在七表八里等繁杂分类上纠缠不清。切脉最关键的是浮脉和沉脉，其次是迟脉和数脉，再次是虚脉和实脉（注：原文为大小、虚实，此处按中医常规逻辑及后文“十脉”归纳，通常指浮沉迟数滑涩虚实大小，原文顺序略有不同，依原文翻译），再次是涩脉和滑脉而已。懂得这十种脉象，那么九种人的疾病就不能超出这个范围。至于死脉，更是容易观察到的。不过是像鱼虾游动、禽鸟啄食、屋漏滴水、弹石敲击、劈索断裂、水流断绝这些异象罢了。掌握了这十种脉法的常态，就可以了解六种脉法的变局，那又怎么难以知晓人的疾病呢？《灵枢》中对脉象的形容，不能作为准则。
张真君说：脉诀原本就不必繁多，繁多反而导致晦涩。明确说出十种法则，极其简单扼要，可以作为千秋万代切脉的准则。
人有南北之分，这种区别在于体质的强弱。南方人的体质虚弱，远远不及北方人的强壮。然而，南方人中也有比北方人强壮的，北方人中也有比南方人虚弱的，也不能一概而论。但是，笼统地用南北地域来划分强弱，也是绝对不可以的，应当根据具体的人来治病，不能拘泥于南北地域来治疗强弱问题。因为天下之人有偏阴和偏阳的区别，偏于阳的人，即使出生在南方，身体也强壮；偏于阴的人，即使出生在北方，身体也虚弱。所以，偏于阳的人，适宜使用寒凉性质的药物；偏于阴的人，适宜使用温热性质的药物。
张真君说：对。
雷真君说：疾病中的寒热症状，一半是由外来的邪气造成的，但也有没有外邪而身体出现寒热的情况，这一点不可不知道。没有外邪而身体出现寒热，是由于肝气郁结而不能宣发，胆气也随之郁结。木气的性质既然郁滞不通，心气自然也不舒展，心、肝、胆三经都郁结，那么脾胃之气就无法运化，肺金得不到滋养，肺气就不刚强，上部缺乏清肃之气下行，而木气因缺少制约（金克木）而妄动，土气想要发泄却不能，于是产生寒热，看起来像疟疾但不是疟疾，而且无法停止。如果此时使用祛除邪气的药物，病情反而会加重，只有疏解木气的郁结，寒热症状自然就会消除。
Lei Zhenjun said: The principles of pulse diagnosis have already been thoroughly expounded in the *Huangdi Neijing* (Yellow Emperor's Inner Canon), and Wang Shuhe further elucidated them. What more is there for me to say? Nevertheless, there are still aspects that are not fully covered, which must be discussed. Generally speaking, the more one discusses pulse diagnosis, the more obscure its core meaning becomes. I advocate simplicity and essentialism in palpating the pulse, rather than getting entangled in complex classifications such as Seven Superficial and Eight Interior pulses. The most crucial aspects of pulse palpation lie in Floating (Fu) and Deep (Chen) pulses; next are Slow (Chi) and Rapid (Shuo) pulses; then Large (Da) and Small (Xiao) pulses; then Deficient (Xu) and Excess (Shi) pulses; and finally, Choppy (Se) and Slippery (Hua) pulses. Understanding these ten pulse types means that diseases in nine types of people cannot escape this framework. As for death pulses, they are even easier to observe. They merely present as anomalies resembling the swimming of fish and shrimp, the pecking of birds, dripping water from a leaking roof, stones being struck, ropes being split, or flowing water stopping. Knowing the normalcy of these ten methods allows one to understand the variations of the six methods; how could it be difficult to know human diseases? The descriptions of pulse images in the *Ling Shu* (Spiritual Pivot) should not be taken as absolute standards.
Zhang Zhenjun said: Pulse principles need not be numerous; too many only lead to obscurity. Clearly stating ten methods is extremely simple and essential, serving as a standard for pulse diagnosis for all generations.
Humans differ by North and South, a distinction based on strength and weakness. Southerners are far weaker than Northerners. However, some Southerners are stronger than some Northerners, and some Northerners are weaker than some Southerners; thus, generalizations cannot be applied universally. Nevertheless, it is absolutely incorrect to simply categorize strength and weakness by geographical origin. One must treat individuals based on their specific conditions, not rigidly adhere to North-South distinctions. This is because people in the world are divided into those biased toward Yin and those biased toward Yang. Those biased toward Yang, even if born in the South, will be strong; those biased toward Yin, even if born in the North, will be weak. Therefore, those biased toward Yang should use cold and cool remedies; those biased toward Yin should use warm and hot remedies.
Zhang Zhenjun said: Correct.
Lei Zhenjun said: Cold and heat symptoms in diseases are half caused by external pathogens. However, there are cases where cold and heat occur without any external pathogen, which must be known. When cold and heat arise without an external pathogen, it is due to Liver Qi stagnation failing to disperse, with Gallbladder Qi following suit into stagnation. Since the Qi of Wood is stagnant, the Qi of Heart naturally fails to flow smoothly. With the Heart, Liver, and Gallbladder meridians all stagnant, the Qi of Spleen and Stomach fails to transform. Lung Metal lacks nourishment, becoming less firm; the upper body lacks the descending clear and肃 (cleanse/strict) Qi, while Wood lacks fear (control by Metal). Earth desires to vent but cannot, resulting in alternating cold and heat. It resembles Malaria (Nue Ji) but is not Malaria, and it cannot stop. If one uses drugs to dispel pathogens, the condition will worsen. Only by soothing the Qi of Wood can the cold and heat be naturally eliminated.
Zhang Zhenjun said: This is also an original theory. The appropriate formula is Xiaoyao San (Free and Easy Wanderer Powder), adding a large dose of Baishao (White Peony Root) is suitable.
