（《素问·金匮真言论》）
黄帝问曰∶天有八风，经有五风，何谓？（经，经脉也。八风，八方之风也，出《九宫八风篇》。五风，五脏之风也，
出《风论》。）岐伯对曰∶八风发邪，以为经风，触五脏，邪气发病。（八风不得其正，则发为邪气，其中于人，则入为五
经之风，特以所伤之异，故名亦异耳。风自外入，则循经而触于五脏，故发病也。）所谓得四时之胜者，春胜长夏，长夏
胜冬，冬胜夏，夏胜秋，秋胜春，所谓四时之胜也。（春木，夏火，长夏土，秋金，冬水，五时五气，互有克胜。所胜为
邪，则不胜者受之。天之运气，人之藏气，无不皆然。此节义与《六节藏象论》同，详运气类二。）东风生于春，病在肝，
俞在颈项。（上文言四时之胜者能为病，此下言邪气随时之为病也。东风生于春，木气也，故病在肝。春气发荣于上，故
俞应于颈项。）南风生于夏，病在心，俞在胸胁。（火气应于心。心脉循胸出胁，而南方之气主于前，故俞在胸胁。）西风
生于秋，病在肺，俞在肩背。（金之气也，故病在肺。肺居上焦，附近肩背，故俞应焉。）北风生于冬，病在肾，俞在腰
股。（水之气也，故病在肾。腰为肾之府，与股接近，故俞应焉。）中央为土，病在脾，俞在脊。（脊居体中，故应土也。）
故春气者病在头，（阳气上升也。）夏气者病在藏，（在藏言心，心通夏气，为诸藏之主也。）秋气者病在肩背，（肺之应也。）
冬气者病在四肢。（上文北方言在腰股，此言在四肢者，盖腰股属阴，四肢气薄，皆易于受寒者也。）故春善病鼽衄，（风
邪在头也。鼽音求。衄，女六切。）仲夏善病胸胁，（胸胁近心也。）长夏善病洞泄寒中，（风寒犯脾也。）秋善病风疟，（暑
汗不出，风寒袭于肤腠也。）冬善病痹厥。（寒邪在四肢也。）故冬不按跷，春不鼽衄，（按跷，谓按摩肢节以行导引也。
三冬元气伏藏在阴，当伏藏之时而扰动筋骨，则精气泄越，以致春夏秋冬各生其病。故冬宜养藏，则春时阳气虽升，阴
精自固，何有鼽衄及如下文之患？按跷且不可，则冒寒妄劳益可知矣。跷音乔，又极虐切。）春不病颈项，仲夏不病胸胁，
长夏不病洞泄寒中，秋不病风疟，冬不病痹厥飧泄而汗出也。（此节五句亦皆由冬不按跷所致，盖水王则生春木，木王则
生夏火，火王则生长夏土，土王则生秋金，金王则生冬水，故可免四时之病。飧音孙。）夫精者身之本也，故藏于精者，
春不病温。（人身之精，真阴也，为元气之本。精耗则阴虚，阴虚则阳邪易犯，故善病温。此正谓冬不按跷则精气伏藏，
阳不妄升则春无温病，又何虑乎鼽衄颈项等病？）夏暑汗不出者，秋成风疟。此平人脉法也。（夏月伏暑而汗不出，则暑
邪内蓄，以至秋凉凄切之时，寒热相争，乃病风疟。故《热论篇》曰∶暑当与汗皆出勿止也。以上二节，一言冬宜闭藏，
一言夏宜疏泄。冬不藏精则病温，夏不汗泄则病疟。阴阳启闭，时气宜然。此举冬夏言，则春秋在其中矣。凡四时之气，
顺之则安，逆之则病，是即平人之脉法。脉法者，言经脉受邪之由然也。）
(From *Suwen: Jin Gui Zhenyan Lun*)
Huangdi asked: "The heaven has Eight Winds (Bafeng, winds from eight directions), and the meridians have Five Winds (Wufeng, wind pathogens affecting the five zang organs). What does this mean?"
Qibo replied: "The Eight Winds generate pathogenic factors, becoming wind pathogens that invade the meridians, touching the five zang organs, causing disease due to pathogenic qi."
Regarding the concept of 'overcoming' among the four seasons leading to disease: Spring overcomes Late Summer; Late Summer overcomes Winter; Winter overcomes Summer; Summer overcomes Autumn; Autumn overcomes Spring. This is called the overcoming relationship among the four seasons. [Spring corresponds to Wood, Summer to Fire, Late Summer to Earth, Autumn to Metal, and Winter to Water. The five seasons and their corresponding climates mutually overcome each other. The overcome side generates pathology, and the side that cannot overcome suffers. This applies to both the heavenly luck (Yunqi) and human organ qi.]
East Wind arises in Spring, causing disease in the Liver, with its transport points located at the neck and nape. [East Wind belongs to Wood Qi, thus affecting the Liver. Spring Qi rises and flourishes upward, so the response is at the neck and nape.]
South Wind arises in Summer, causing disease in the Heart, with its transport points located at the chest and hypochondrium. [Fire Qi corresponds to the Heart. The Heart meridian passes through the chest and emerges at the hypochondrium, and Southern Qi governs the anterior aspect, so the response is at the chest and hypochondrium.]
West Wind arises in Autumn, causing disease in the Lungs, with its transport points located at the shoulders and back. [This is Metal Qi, thus affecting the Lungs. The Lungs reside in the Upper Jiao, near the shoulders and back, so the response is there.]
North Wind arises in Winter, causing disease in the Kidneys, with its transport points located at the waist and thighs. [This is Water Qi, thus affecting the Kidneys. The waist is the mansion of the Kidneys, close to the thighs, so the response is there.]
The Center corresponds to Earth, causing disease in the Spleen, with its transport points located at the spine. [The spine is in the center of the body, thus corresponding to Earth.]
Therefore, diseases caused by Spring Qi often affect the head, [because Yang Qi ascends.] Diseases caused by Summer Qi often affect the zang organs, [specifically the Heart, which corresponds to Summer and is the master of all zang organs.] Diseases caused by Autumn Qi often affect the shoulders and back, [corresponding to the Lungs.] Diseases caused by Winter Qi often affect the four limbs. [The previous section mentioned the waist and thighs for the North; here mentioning the four limbs is because the waist and thighs belong to Yin, while the four limbs have thinner Qi and are prone to cold invasion.]
Thus, in Spring, one is prone to rhinorrhea (Qiu) and epistaxis (Nu); [Wind pathogen in the head.] In Mid-Summer, one is prone to chest and hypochondriac disorders; [Chest and hypochondrium are near the Heart.] In Late Summer, one is prone to severe diarrhea (Dongxie) and cold injury in the middle jiao; [Cold and dampness invading the Spleen.] In Autumn, one is prone to wind-malaria (Fengnüe); [Summer heat sweat fails to discharge, allowing cold and wind to invade the skin and interstices.] In Winter, one is prone to Bi syndrome (painful obstruction) and Jue syndrome (cold extremities/reversal); [Cold pathogen in the four limbs.]
Therefore, if one does not perform Anqiao (massage and guided movement) in Winter, one will not suffer from rhinorrhea or epistaxis in Spring. [Anqiao refers to massaging joints and limbs to promote circulation and guided exercises. During the three winter months, Yuan Qi (Original Qi) is hidden within Yin. Disturbing bones and muscles during this time of hiding leads to leakage and depletion of essence and qi, causing diseases in all four seasons. Thus, Winter should be used for nurturing storage. If Spring Yang Qi rises but Yin Essence remains secure, there will be no rhinorrhea or subsequent ailments. If even massage is inadvisable, then exposing oneself to cold and overexertion is certainly worse.] Consequently, one will not suffer from neck and nape disorders in Spring, chest and hypochondriac disorders in Mid-Summer, severe diarrhea and cold injury in Late Summer, wind-malaria in Autumn, or Bi syndrome, Jue syndrome, undigested stool diarrhea (Sunxie), and sweating in Winter. [These five conditions are also caused by failing to hide in Winter. When Water is prosperous, it generates Spring Wood; when Wood is prosperous, it generates Summer Fire; when Fire is prosperous, it generates Late Summer Earth; when Earth is prosperous, it generates Autumn Metal; when Metal is prosperous, it generates Winter Water. Thus, seasonal diseases can be avoided.]
Essence (Jing) is the root of the body. Therefore, those who preserve their essence will not suffer from Warm diseases (Wenbing) in Spring. [Human essence is True Yin, the root of Original Qi. Depletion of essence leads to Yin deficiency, making Yang pathogens easy to invade, hence prone to Warm diseases. This implies that if one hides essence in Winter by avoiding excessive activity, Yang Qi will not rise recklessly, preventing Spring Warm diseases and concerns about rhinorrhea or neck disorders.]
If summer heat is retained without sweating in Summer, it will develop into wind-malaria in Autumn. This is the normal pattern of pulse and disease prevention. [If summer heat is retained internally due to lack of sweating in Summer, when autumn coolness arrives, cold and heat contend, resulting in wind-malaria. As stated in *Re Lun*: "Summer heat should be expelled with sweat; do not stop it." These two sections discuss Winter storage and Summer dispersion. Failure to store essence in Winter leads to Warm diseases; failure to disperse heat via sweating in Summer leads to malaria. The opening and closing of Yin and Yang follow the seasonal climate. By citing Winter and Summer, Spring and Autumn are implied. For all seasonal climates, following them ensures peace, while opposing them causes disease. This is the method of maintaining health. 'Pulse method' here refers to understanding how meridians receive pathogens.]
