异，治化唯一，故不再言同风热者多寒化，异风热者少寒化。出气交变论。）
初之气自庚辰年大寒日巳初，至是岁春分日卯初，六十日有奇。主位少角木，客气阳明金，

此六气之化也。岁气之交，天气胜者，则有阳明之复；地气胜者，则有太阳之复。观其胜复，
各以其法治之。
厥阴风木之气主司天气，少阳相火之气主司地气（在泉），中运为少羽水运。岁中水气不足，导致气化运行滞后于天时。天地之气交互作用：上方显现厥阴风木，其左侧间气为少阴君火，右侧间气为太阴湿土，因此天气受到扰动而政令紊乱；下方显现少阳相火，其左侧间气为阳明燥金，右侧间气为太阳寒水，因此地气端正而令行迅速。风气生于高远之处，炎热随之而起。云气趋向雨府，湿气得以化行。风与火同具生发之德，在天象上对应岁星（木星）和荧惑星（火星）。对应的谷物为青色（苍）和红色（丹），至于间谷则指代那些由间气所生的、名称宏大的谷物。（注：此处以间气之大者来指代其对应的谷物，如太宫、太商等五行相生所生的谷物。）其损耗表现为角音类（毛虫）和羽音类（羽虫）的减少。风邪与燥邪的胜复变化体现在人体之中。（出自《素问·六元正纪大论》）。雨化和风化的胜复规律相同，这是邪气变化的度数。其中，风化数为三，寒化数为一，火化数为七，这是正常的气候变化度数。（出自《素问·六元正纪大论》）。风化属木为主司天之气，苦味属火为主在泉之气，玄色属水为主司中运之气，柔润属土、清肃属金为间气，灼热（君火）为居气。（灼化不称为间气而称为居气，是因为尊崇君火无所不在，不应将其视为间气。出自《素问·至真要大论》）。在万物方面，毛虫安静，羽虫繁育，这是当年适宜生长的物候；介虫（甲壳类）消耗，寒毒不能滋生，这是被地气所制约的结果。（出自《素问·五常政大论》）。然而，当年的岁气和天化显得虚弱，地化显得充盈，应当资助化源（在前一年的大寒十二月预先采取措施），以助长天气中的木气。虽然化源看似虚弱，但中运有水气，水能生木，邪气就会轻微。必须赞助水运，不让邪气占上风。治疗上，用辛凉之品调理上部，用咸寒之品调理下部。畏惧火气的人，不要妄加触犯。（出自《素问·六元正纪大论》）。
岁半之前，由厥阴风木主事。如果风邪过盛，那么天空昏暗尘埃弥漫，云物纷扰。寒气转化为春气，流水不结冰。（此为木气之化）。民众易患胃脘当心部位疼痛，向上支撑两胁，膈咽不通畅，饮食难下，舌根僵硬。进食后呕吐，冷性泄泻，腹胀，溏泄，瘕积，水液闭塞。病本在于脾，诊察脉象在足冲阳脉。治疗方法是用辛凉之品平抑风邪，辅以苦甘之品，用甘味缓急，用酸味泻实。（出自《素问·至真要大论》）。
岁半之后，由少阳相火主事。如果火邪内盛，那么原野火光通明，寒热交替发作。民众易患赤白痢疾，少腹疼痛，小便赤涩，严重时出现便血。治疗方法用咸冷之品主治，辅以苦辛之品，用酸味收敛，用苦味发散。（出自《素问·至真要大论》）。
岁运的变化，因水气不及，纪年称为“涸流”，这被称为反常之阳。肾藏功能不举，脾土化气反而昌盛。夏长之气宣布，蛰伏的虫子不隐藏。土地湿润，泉水减少，草木枝条茂盛，荣华秀美充满旺盛。其气机滞涩，其作用表现为渗泄，其变动表现为坚硬或停止，其发作表现为干燥枯槁，其主宰表现为埃尘郁结、天色昏翳，其病症表现为痿证、厥逆、下部坚硬。（出自《素问·五常政大论》）。其气化兼有其所不胜之气的影响，四维方位出现湍急水流、湿润、埃尘、云气的气化，就会有不时产生的和风生发之应。如果四维方位出现埃尘昏蒙、暴雨骤降的变化，就会有不时产生的飘荡摇落之复气。其灾祸发生在北方，其对应的脏腑是肾，其病邪内舍于腰脊骨髓，外在表现于溪谷和膝盖，都应用苦味药物调和其中。（注：厥阴和少阳的政令，上下没有克贼罪过的差异，治疗原则一致，所以不再重复说明同风热者多寒化，异风热者少寒化。出自《素问·气交变大论》）。
初之气，从庚辰年大寒日巳时初刻开始，到本年春分日卯时初刻结束，共六十多天。主气为少角木，客气为阳明金，中见水运。金克木，水运介入其间，寒气开始肃杀，杀气方才到来。民众易患右下方的寒症。（出自《素问·六元正纪大论》）。适宜治疗阳明客气，用酸味补益，用辛味泻除，用苦味宣泄。岁谷宜选青色（属木），间谷（指代间气之大者对应的谷物）宜选黍（属火，出自《素问·至真要大论》）。
二之气，从春分日卯时正刻开始，到小满日丑时初刻结束，共六十多天。主气为太征火，客气为太阳水，中见水运。气与运相同，寒气未去，花开如雪，水结成冰，杀气施行教化，霜乃降落，名草顶部焦枯，寒雨频繁到来，阳气重新化生。民众易患中部热症。适宜治疗太阳客气，用苦味补益，用咸味泻除，用苦味坚阴，用辛味润燥。岁谷宜选青色，间谷宜选稷（属土）。此阶段，不要触犯司天之气的寒性。
三之气，从小满日寅时初刻开始，到大暑日子时初刻结束，共六十多天。主气为太征火，客气为厥阴木，中见水运。岁运之水，克制火气并生助木气，所以天政布散，风气按时兴起。民众易患流泪、耳鸣、震颤、眩晕。适宜治疗厥阴客气，用辛味补益，用酸味泻除，用甘味缓急。岁谷宜选青色，间谷宜选稻（属金）。
四之气，自大暑日子时正刻开始，到秋分日戌时正刻结束，共六十多天。主气为少宫土，客气为少阴火，中见水运。湿热闷热相互搏结，争胜于左上方。民众易患黄疸并伴有浮肿。适宜治疗少阴客气，用咸味补益，用甘味泻除，用酸味收敛。岁谷宜选红色，间谷宜选豆（属水）。
五之气，从秋分日亥时初刻开始，到小雪日酉时初刻结束，共六十多天。主气为太商金，客气为太阴土，中见水运。土气刑克运水，燥湿更替取胜，深沉的阴气布散，寒气及身，风雨乃行。适宜治疗太阴客气，用甘味补益，用苦味泻除，用甘味缓急。岁谷宜选红色，间谷宜选麻（属木）。
终之气，从小雪日酉时正刻开始，到大寒日未时正刻结束，共六十多天。主气为少羽水，客气为少阳火，中见水运。岁运得位，但畏惧火气当令，阳气大肆化行，蛰伏的虫子出来活动，流水不结冰，地气大发，草木生长，人感觉舒适。其病症为温病、疠气。适宜治疗少阳客气，用咸味补益，用甘味泻除，用咸味软坚。岁谷宜选红色，间谷宜选豆（属水）。
这就是六气的气化规律。岁气交接之时，天气胜者，会有阳明之复气；地气胜者，会有太阳之复气。观察其胜复变化，各自用相应的法治之。
When Jueyin Wind-Wood governs the Heaven Qi, Shaoyang Ministerial Fire governs the Earth Qi (Zai Quan), and the central movement is Shao Yu Water Yun. Since the year's Water Qi is insufficient, the Qi transformation operates later than the celestial timing. The interaction of Heaven and Earth Qi manifests as follows: Above, Jueyin Wind-Wood appears; its left interstitial Qi is Shaoyin Monarch Fire, and its right interstitial Qi is Taiyin Damp-Earth; thus, the Heaven Qi is disturbed and its administration is chaotic. Below, Shaoyang Ministerial Fire appears; its left interstitial Qi is Yangming Dryness-Metal, and its right interstitial Qi is Taiyin Cold-Water; thus, the Earth Qi is upright and its commands are swift. Wind arises from high distances, and intense heat follows it. Clouds tend toward the Rain House, and Dampness transformation proceeds. Wind and Fire share the same virtue, corresponding in the heavens to Sui Xing (Jupiter) and Ying Huo (Mars). The corresponding grains are Cang (Green/Cyan) and Dan (Red); regarding inter-grains, it refers to those named after the greater interstitial Qi (i.e., grains generated by the five phases such as Tai Gong and Tai Shang). Their depletion affects the Jiao category (hairy animals) and Yu category (feathered animals). Wind and Dryness excess and recovery manifest within. (From *Suwen: Liuyuan Zhengji Dalun*). The excess and recovery of Rain transformation and Wind transformation are identical, representing the degree of pathogenic Qi transformation. Among these, Wind transformation is three, Cold transformation is one, and Fire transformation is seven; this is the degree of normal transformation. (From *Suwen: Liuyuan Zhengji Dalun*). Wind transformation belongs to Wood and governs Heaven Qi; Bitter transformation belongs to Fire and governs Earth Qi; Xuan (Black/Dark) transformation belongs to Water and governs the Central Yun; Rou (Soft/Moist) transformation belongs to Earth and Qing (Clear/Pure) transformation belongs to Metal as interstitial Qi; Zhuo (Burning/Scorching, referring to Monarch Fire) governs the resident Qi. (Zhuo transformation is not called interstitial Qi but resident Qi, honoring that Monarch Fire resides everywhere and should not be treated as an interstitial Qi. From *Suwen: Zhiyao Dalun*). In terms of things, Mao Chong (hairy animals) remain quiet, and Yu Chong (feathered animals) breed; this is what suits the year's objects. Jie Chong (shelled animals) are depleted, and Cold Du (toxicity) does not generate; this is constrained by Earth Qi. (From *Suwen: Wuchang Zheng Dalun*). However, since the year's Qi and Heaven transformation are deficient while Earth transformation is abundant, one should nourish the Source of Transformation (by preparing in the 12th month before Da Han) to assist the Wood Qi of Heaven. Although the Source of Transformation seems weak, with Water Yun in the center, Water generates Wood, so pathogenic Qi becomes slight. One must support the Water Yun to prevent pathogenic Qi from prevailing. Treat the upper part with Pungent-Cool agents and the lower part with Salty-Cold agents. Those fearing Fire Qi should not act recklessly against it. (From *Suwen: Liuyuan Zhengji Dalun*).
Before the middle of the year, Jueyin governs. If Wind Yin prevails excessively, the vast sky becomes dusty and dim, and clouds and objects are disturbed. Cold transforms into Spring Qi, and flowing water does not freeze. (This is Wood transformation). People suffer from pain in the epigastrium at the heart's location, radiating upward to support both hypochondria, obstruction in the diaphragm and throat, difficulty swallowing food, and stiffness of the tongue root. Vomiting occurs after eating, along with cold diarrhea, abdominal distension, loose stools, mass accumulation, and fluid closure. The disease originates in the Spleen; diagnosis focuses on the Chongyang pulse of the foot. The method is to level with Pungent-Cool agents, assist with Bitter-Sweet agents, use Sweet agents to relax tension, and use Sour agents to drain excess. (From *Suwen: Zhiyao Dalun*).
After the middle of the year, Shaoyang governs. If Fire Yin overflows internally, flames illuminate the suburbs, and cold and heat alternate. People suffer from dysentery with red and white discharge, lower abdominal pain, dark urine, and in severe cases, bloody stools. The treatment uses Salty-Cold agents as the main therapy, assisted by Bitter-Pungent agents, using Sour agents to astringe and Bitter agents to vent. (From *Suwen: Zhiyao Dalun*).
The transformation of the annual Yun, due to Water deficiency, is recorded as "He Liu" (Dried Stream), which is called Reverse Yang. The storage function of the Zang organs is inactive, while the transformation Qi of the Spleen flourishes. The Long Qi (Summer growth Qi) is proclaimed, and hibernating insects do not hide. The earth is moist, springs and wells decrease, grass and trees flourish abundantly. Its Qi is stagnant, its function is seepage and drainage, its movement is hardness or stillness, its manifestation is dryness and withering, its dominance is dust and oppression with dim vision, and its diseases are Wei Bi (flaccidity syndrome), Jue Ni (cold extremities), and hardness below. (From *Suwen: Wuchang Zheng Dalun*). Its transformation combines with the Qi it cannot overcome. If the four corners exhibit transformations of rapid flow, moisture, dust, and clouds, there will be occasional responses of gentle wind and generation. If the four corners exhibit changes of dust, dimness, and sudden heavy rain, there will be occasional recoveries of drifting and shaking. The disaster occurs in the North, corresponding to the Kidney organ. The disease resides internally in the waist, spine, and marrow, and externally in the溪谷 (valleys/capillaries) and knees; all should be harmonized internally with Bitter agents. (Note: For Jueyin and Shaoyang administrations, there is no difference in the fault of mutual overcoming above and below; the treatment principle is unique, so it is not repeated that similar wind-heat cases have more cold transformations, while different wind-heat cases have fewer cold transformations. From *Suwen: Qijiao Bian Lun*).
The First Qi begins from the Si hour of Da Han in the Geng Chen year until the Mao hour of Chun Fen of this year, lasting more than sixty days. The Main Position is Shao Jiao Wood, the Guest Qi is Yangming Metal, and the central view is Water Yun. Metal overcomes Wood, and Water Yun intervenes; Cold begins to肃杀 (purge and kill), and the Killing Qi arrives. People suffer from Cold in the lower right. (From *Suwen: Liuyuan Zhengji Dalun*). It is appropriate to treat the Yangming Guest Qi, tonifying with Sour agents, draining with Pungent agents, and purging with Bitter agents. The Year Grain should be Cang (Wood), and the Inter Grain (referring to the grain of the greater interstitial Qi) should be Shu (Fire, from *Suwen: Zhiyao Dalun*).
The Second Qi begins from the Mao hour of Chun Fen until the Chou hour of Xiao Man, lasting more than sixty days. The Main Position is Tai Zheng Fire, the Guest Qi is Taiyang Water, and the central view is Water Yun. The Qi and Yun are the same; Cold does not depart, flowers appear like snow, water freezes, the Killing Qi implements transformation, frost descends, the tops of famous grasses scorch, cold rains arrive frequently, and Yang Qi recovers transformation. People suffer from Heat in the middle. It is appropriate to treat the Taiyang Guest Qi, tonifying with Bitter agents, draining with Salty agents, firming with Bitter agents, and moistening with Pungent agents. The Year Grain should be Cang, and the Inter Grain should be Ji (Earth). In this Qi, do not violate the Cold of the Si Qi.
The Third Qi begins from the Yin hour of Xiao Man until the Zi hour of Da Shu, lasting more than sixty days. The Main Position is Tai Zheng Fire, the Guest Qi is Jueyin Wood, and the central view is Water Yun. The Year Yun Water controls Fire and generates Wood, so the Heaven Administration spreads, and Wind rises on time. People suffer from tearing, tinnitus, tremors, and dizziness. It is appropriate to treat the Jueyin Guest Qi, tonifying with Pungent agents, draining with Sour agents, and relaxing with Sweet agents. The Year Grain should be Cang, and the Inter Grain should be Dao (Metal).
The Fourth Qi begins from the Zi hour of Da Shu until the Xu hour of Qiu Fen, lasting more than sixty days. The Main Position is Shao Gong Earth, the Guest Qi is Shaoyin Fire, and the central view is Water Yun. Humid heat and dampness struggle and contend in the upper left. People suffer from Jaundice accompanied by swelling. It is appropriate to treat the Shaoyin Guest Qi, tonifying with Salty agents, draining with Sweet agents, and astringing with Sour agents. The Year Grain should be Dan, and the Inter Grain should be Dou (Water).
The Fifth Qi begins from the Hai hour of Qiu Fen until the You hour of Xiao Xue, lasting more than sixty days. The Main Position is Tai Shang Metal, the Guest Qi is Taiyin Earth, and the central view is Water Yun. Earth penalizes the Yun, Dryness and Dampness alternate in victory, deep Yin spreads, Cold reaches the body, and wind and rain occur. It is appropriate to treat the Taiyin Guest Qi, tonifying with Sweet agents, draining with Bitter agents, and relaxing with Sweet agents. The Year Grain should be Dan, and the Inter Grain should be Ma (Wood).
The Final Qi begins from the You hour of Xiao Xue until the Wei hour of Da Han, lasting more than sixty days. The Main Position is Shao Yu Water, the Guest Qi is Shaoyang Fire, and the central view is Water Yun. The Year Yun obtains its position but fears the command of Fire; Yang undergoes great transformation, hibernating insects emerge, flowing water does not freeze, Earth Qi erupts, grass grows, and people feel comfortable. The diseases are Wen Bing (Warm Diseases) and Li Qi (Plague Qi). It is appropriate to treat the Shaoyang Guest Qi, tonifying with Salty agents, draining with Sweet agents, and softening hardness with Salty agents. The Year Grain should be Dan, and the Inter Grain should be Dou (Water).
This is the transformation of the Six Qi. At the intersection of Year Qi, if Heaven Qi prevails, there will be a recovery of Yangming; if Earth Qi prevails, there will be a recovery of Taiyang. Observe their excess and recovery, and treat each with its respective method.
