平按∶此篇自篇首至末，见《灵枢》卷十一第七十四《论疾诊尺》篇。又自冬伤于
寒至咳嗽，见《素问》卷二第五《阴阳应象大论》篇，又见《甲乙》卷十一第五。
四时之变，寒暑之胜，重阴必阳，重阳必阴，故阴主寒，阳主热，故寒甚则热，热
甚则寒，（日中阳陇，必降为阴；夜半阴极，必升为阳。）故曰∶寒生热，热生寒，此
阴阳之变也。（十一月极寒，一阳爻生，即寒生热也。五月一阴爻生，即热生寒也。）
故曰∶冬伤于寒，春生瘅热；（寒，冬之气也。伤，过多也。人之冬月，受寒过多，至
春必属瘅热之病，此为寒生热也。）春伤于风，夏生飧泄肠 ；（风，春之气也。受风
过多，极为飧泄肠 ，此为风生泄也。）夏伤于暑，秋生 疟；（暑，夏之气也。受暑
过多，极为 疟，此为暑生疟也。）秋伤于湿，冬生咳嗽。是谓四时之序。（湿，秋之
气也。受湿过多，极为咳嗽，此为湿生咳也。此是四时必□□□不可易。平按∶注四时下
原抄有必字，必下缺三字，最下一字下半作文。袁刻四时下无必字，作之序支三字，不
合。兹于必字下，仍空三格。）
【平按】：本篇从开头到“勿止”这一句，见于《素问》卷九第三十一《热论》篇。篇末的一句，见于《素问》卷十六第六十一《水热穴论》，同时也见于《甲乙经》卷七第一。
凡是患伤寒病而转化为温病（以发热为主、不恶寒或微恶寒的病证）的，在夏至日之前发病的称为温病，在夏至日之后发病的称为暑病（夏季感受暑热之邪所致的病证）。患病时应当让汗液排出，不要强行止汗。
所谓玄府（汗孔），就是汗液的出口。（冬季轻微受寒，在夏至以前发作的为温病；冬季严重受寒，在夏至以后发作的为暑病。暑病的热气随汗液一起排出，这表示热邪已去，所以不要止汗。汗出的孔隙称为玄府，指的是腠理。）【平按】：《素问》和《甲乙经》中“病者当与汗”写作“暑当与汗”。《甲乙经》中“汗空”写作“汗孔”。另外，《素问》新校正引用杨上善的注解说，“发于”中的两个“于”字均作为助词处理。
【平按】：本篇从开头到结尾，见于《灵枢》卷十一第七十四《论疾诊尺》篇。另外从“冬伤于寒”到“咳嗽”，见于《素问》卷二第五《阴阳应象大论》篇，同时也见于《甲乙经》卷十一第五。
四季的变化，寒暑的交替，阴气重了必转化为阳，阳气重了必转化为阴，所以阴主寒，阳主热，因此寒极则生热，热极则生寒。（中午阳气隆盛，必然下降转为阴；半夜阴气极盛，必然上升转为阳。）所以说：寒生热，热生寒，这是阴阳变化的规律。（十一月是极寒之时，但一阳爻开始生成，这就是寒生热的道理。五月一阴爻开始生成，这就是热生寒的道理。）所以说：冬季受寒，春季发生瘅热病（高热、烦渴的病证）；（寒，是冬季的气候。伤，指过度。人在冬季，如果受寒过多，到了春天必定会患上瘅热病，这就是寒生热的表现。）春季受风邪，夏季发生飧泄肠澼（大便稀薄、完谷不化及伴有脓血的腹泻）；（风，是春季的气候。受风邪过多，就会极度发展为飧泄肠澼，这就是风生泄的表现。）夏季受暑邪，秋季发生疟疾（寒热往来、休作有时的病证）；（暑，是夏季的气候。受暑邪过多，就会极度发展为疟疾，这就是暑生疟的表现。）秋季受湿邪，冬季发生咳嗽。（湿，是秋季的气候。受湿邪过多，就会极度发展为咳嗽，这就是湿生咳的表现。这是四季必然的顺序，不可改变。【平按】：注文中“四时”下原抄本有“必”字，“必”字下缺三个字，最下面一个字的下半部分像“文”字。袁刻本“四时”下没有“必”字，写作“之序支”三个字，不合文理。此处就在“必”字下，仍空三格。）
[Ping An]: This section, from the beginning of the chapter to "do not stop," is found in Volume 9, Chapter 31 "Re Lun" (Treatise on Heat Diseases) of the *Su Wen* (Basic Questions). The final sentence of this section is found in Volume 16, Chapter 61 "Shui Re Xue Lun" (Treatise on Water and Heat Acupoints) of the *Su Wen*, and also in Volume 7, Chapter 1 of the *Jia Yi Jing* (Systematic Classic of Acupuncture and Moxibustion).
Whenever a disease originating from Shang Han (Cold Damage) transforms into Wen Bing (Warm Disease), those manifesting before the Summer Solstice are classified as Wen Bing, while those manifesting after the Summer Solstice are classified as Shu Bing (Summerheat Disease). In such cases, sweat should be allowed to discharge naturally; it should not be forcibly stopped.
The term "Xuan Fu" refers to the pores through which sweat exits. [If one suffers mild cold injury in winter, the disease manifests as Wen Bing before the Summer Solstice. If one suffers severe cold injury in winter, the disease manifests as Shu Bing after the Summer Solstice. In Shu Bing, the pathogenic heat is expelled along with sweat; since the heat has departed, sweating should not be suppressed. The pores where sweat emerges are called Xuan Fu, referring to the Cou Li (interstices of skin and muscles).] [Ping An]: The *Su Wen* and *Jia Yi Jing* read "Shu dang yu han" (Summerheat should be treated with sweating) instead of "Bing zhe dang yu han." The *Jia Yi Jing* reads "Han Kong" (sweat hole) instead of "Han Kong." Additionally, the New Collation of the *Su Wen* cites Yang Shangshan's commentary, stating that both instances of "yu" in "fa yu" function as grammatical particles.
[Ping An]: This entire section, from beginning to end, is found in Volume 11, Chapter 74 "Lun Ji Zhen Chi" (Discourse on Diagnosing Diseases by Observing the Forearms) of the *Ling Shu* (Spiritual Pivot). Furthermore, the passage from "Winter injury by cold" to "cough" is found in Volume 2, Chapter 5 "Yin Yang Ying Xiang Da Lun" (Great Treatise on Yin-Yang Correspondences) of the *Su Wen*, and also in Volume 11, Chapter 5 of the *Jia Yi Jing*.
The changes of the four seasons and the mutual overcoming of cold and summerheat follow the principle that extreme Yin transforms into Yang, and extreme Yang transforms into Yin. Therefore, Yin governs cold, and Yang governs heat; thus, extreme cold generates heat, and extreme heat generates cold. (At noon, when Yang Qi is at its peak, it must decline and transform into Yin; at midnight, when Yin Qi is at its extreme, it must rise and transform into Yang.) Hence it is said: Cold generates heat, and heat generates cold; this is the transformation of Yin and Yang. (In the eleventh lunar month, during extreme cold, the first Yang line begins to generate, illustrating how cold gives rise to heat. In the fifth lunar month, the first Yin line begins to generate, illustrating how heat gives rise to cold.) Hence it is said: Injury by cold in winter leads to Dan Re (intense heat) disease in spring; [Cold is the Qi of winter. 'Shang' implies excess. If humans suffer excessive cold exposure in winter, they will inevitably develop Dan Re disease in spring, demonstrating that cold generates heat.] Wind injury in spring leads to Sun Xie Chang Pi (diarrhea with undigested food and intestinal dysentery) in summer; [Wind is the Qi of spring. Excessive wind exposure leads to severe Sun Xie Chang Pi, demonstrating that wind generates diarrhea.] Summerheat injury in summer leads to Nue (Malaria/alternating chills and fever) in autumn; [Summerheat is the Qi of summer. Excessive summerheat exposure leads to severe Nue, demonstrating that summerheat generates malaria.] Dampness injury in autumn leads to cough in winter. [Dampness is the Qi of autumn. Excessive dampness exposure leads to severe cough, demonstrating that dampness generates cough.] This is referred to as the sequence of the four seasons. [This represents the inevitable order of the four seasons, which cannot be altered. [Ping An]: The original manuscript notes have the character "bi" (must) after "si shi" (four seasons), followed by three missing characters, with the bottom part of the last character resembling "wen." Yuan's printed edition lacks "bi" after "si shi" and reads "zhi xu zhi" (three characters), which does not fit the context. Here, following "bi," three spaces are left blank.]]
