【素问】上古时代的人，那些懂得养生之道的人，效法阴阳变化的规律，运用适宜的养生方法。饮食有节制，起居有常规，不随意过度劳累，所以能够形体与精神协调统一。（如果神离开了形体就会死亡。）从而享尽天赋的自然寿命，活到一百岁才离开人世。现在的人却不是这样。把酒当作汤水般豪饮，把妄为当作常态，醉酒后行房事，因纵欲而耗竭精气，因散逸而损耗真气。不知道保持精气的充盈（保持充盈，是担心倾覆的意思），不能适时地调摄精神，只求满足一时的快乐，违背了养生的乐趣（放纵嗜欲之心，违背了生养的愉悦）。起居没有节制，所以不到五十岁就衰老了。那上古时代的圣人教导百姓，都说要按时避开虚邪贼风等致病因素。心境恬淡虚无，真气就能顺从。（这就是老子所说的恍惚中有形象、杳冥中有精微的意义。）精神内守，疾病从哪里产生呢？女子到了七岁（王冰注：老阳之数穷于九，女子属少阴，所以用少阳之数来配合它），肾气旺盛，牙齿更换，头发生长。（肾主骨，是精血之府库，牙齿是骨的余气，头发是血的余气。）十四岁时天癸至（经水属于北方的壬癸水），任脉通畅，太冲脉盛满，月经按时来潮，所以能够生育。（冲脉为血海，任脉主胞胎，这两条经脉相互资助，所以能生育。经水每月一至，运行有常度，所以叫经水，也叫月水。如果过期不来就是病证。男子冲任脉盛满，则向上荣润而生胡须；女子冲任脉盛满，则向下运行而为月经，所以没有胡须。）二十一岁时肾气平和，所以智齿长出，身体长到极点。（最后长出的牙齿，人的身高长到这里就停止了。）二十八岁时筋骨坚固，头发长到极点，身体强盛壮实。三十五岁时阳明脉开始衰退，面部开始憔悴，头发开始脱落。（足阳明胃经起于鼻翼，交会于鼻根中，向下沿鼻外侧，进入上齿中，复出挟口环绕嘴唇，下交于承浆穴，向后沿下颌后出大迎穴，沿颊车穴，上行耳前，经过客主人穴，沿发际，至额颅。手阳明大肠经上行颈部贯颊，入下齿中，复出挟口。这两条经脉都营养面部，衰退则面部憔悴，头发脱落。）四十二岁时三阳脉在头部开始衰退，面部全都憔悴，头发开始变白。（三阳经脉，都上行头面。）四十九岁时任脉虚衰，太冲脉气血衰少，天癸枯竭，地道不通（到这里月经断绝）。所以形体败坏而不能生育了。（女子气有余而血不足，因为经常失血脱泄的缘故。）男子到了八岁（王冰注：老阴之数尽于十，男子属少阳，所以用少阴之数来配合它。《易经》说：天九地十，就是这个数）。肾气充实，头发生长，牙齿更换。十六岁时肾气盛满，天癸至（阳精），精气满溢而排泻，阴阳调和，所以能够生育。二十四岁时肾气平和，筋骨强劲有力，所以智齿长出，身体长到极点。三十二岁时筋骨隆盛，肌肉丰满壮实。四十岁时肾气衰退，头发脱落，牙齿枯槁。四十八岁时阳气衰竭于上部，面部憔悴，鬓角头发斑白。五十六岁时肝气衰退，筋脉不能灵活运动，天癸枯竭，精液减少，肾脏衰退，形体极度衰弱。六十四岁时牙齿和头发脱落（卦气已尽）。肾主水，接受五脏六腑的精气而贮藏它，所以五脏精气盛满，才能向外排泄。现在五脏都衰退了，筋骨松弛无力，天癸已经耗尽，所以鬓发变白，身体沉重，行走不稳，而且不能生育了。有的人虽然年纪老了，却还有生育能力，为什么呢？这是因为他们天赋寿命超过常人，气脉常常通畅，而且肾气有余。这些人虽然有生育能力，但男子不超过六十四岁，女子不超过四十九岁，天地赋予的精气都竭尽了。（王冰注：生育的寿限，不过这个数目。马云的说法不对。）（出自《上古天真论》）
【素问】春季三个月，这叫作发陈（推陈出新）。天地生机俱旺，万物繁荣。（天地交泰，万物通达。）晚睡早起，在庭院中阔步慢行，披散头发，舒缓形体，以使意志生发。有生发之意而不杀伐，给予而不掠夺，奖赏而不惩罚，这是顺应春气的表现，也是养生的原则。违背它就会损伤肝脏，到了夏天会发生寒性病变，供给夏季生长的力量就少了。（火是木之子，发生寒变则木不能生火，无法奉助夏季生长的命令。）夏季三个月，这叫作蕃秀（繁茂秀美）。天地之气相交，万物开花结果。晚睡早起，不要厌恶烈日。（厌，意为满足。不要过分在日中行伤暑，这与冬天必须等待阳光相反。）使意志不发怒，使精神华美秀外，使气机得以宣泄，好像喜爱的事物在外面一样。（顺应阳气而主外）。这是顺应夏气的表现，也是养长的原则。违背它就会损伤心脏，到了秋天会发生疟疾，供给秋季收敛的力量就少了。（没有气来奉助秋季收敛的命令。）冬至时容易患重病。（水克火。）秋季三个月，这叫作容平（万物形态平定）。天气急劲，地气清明。早睡早起，与鸡鸣同时起床。使意志安宁，以缓和秋气的肃杀，收敛神气，使秋气平和。不要使志意外驰，使肺气清肃。这是顺应秋气的表现，也是养收的原则。违背它就会损伤肺脏，到了冬天会发生完谷不化的泄泻，供给冬季闭藏的力量就少了。（没有气来奉助冬季闭藏的命令。）冬季三个月，这叫作闭藏。水结冰，地冻裂，不要扰动阳气。（阳气潜藏。）早睡晚起，一定要等到太阳出来。使气机潜伏隐匿，好像有私心秘密，好像自己有所收获。（与夏季正好相反）。远离寒冷，趋向温暖，不要使皮肤开泄出汗，以免气机频繁耗夺。（告诫不要妄自发汗，导致阳气泄脱）。这是顺应冬气的表现，也是养藏的原则。违背它就会损伤肾脏，到了春天会发生痿厥，供给春季生发的力量就少了。（没有气来奉助春季生发的命令。）（出自《四气调神大论》）
【素问】天通过五气供养人。（吴崑注：五气不仅仅指臊焦香腐腥这五种气味，风寒暑湿燥分别主宰五脏，受纳它们而不亢盛有害，都能滋养人。）地通过五味供养人。五气从鼻子吸入。（鼻接受无形的天气。）贮藏于心肺，向上使面色红润明亮，声音洪亮。（心主管面色，肺主管声音。）五味从口摄入。（口接受有形的地气。）贮藏于肠胃，味道有所贮藏，用来滋养五气，气机调和则生命产生，津液相互生成，神气自然产生。（积精可以生神。）（出自《六节藏象论》）
【灵枢】水谷进入口中，输送到肠胃，其中的液体分为五种。天气寒冷衣服单薄时就化为尿和气。（前为尿，后为气。）天气炎热衣服厚实时就化为汗。悲哀时气机并聚就化为泪。体内热而胃缓时就化为唾。邪气内逆则气机闭塞不通，就形成水胀。我想了解它的道理。回答说：水谷都进入口中，味道有五种，各自注入相应的海。（分别注入五脏。）津液各自走它们的通道，所以三焦发出气。（宗气出于上焦，营气出于中焦，卫气出于下焦。）用来温煦肌肉，充养皮肤，成为津。流动而不停止的是液。天气暑热衣服厚实则腠理开泄，所以出汗。寒气停留在分肉之间，凝聚成沫就产生疼痛。天气寒冷则腠理闭合，气湿不行。（不在肌表运行，所以下流成为尿。）水下流到膀胱就成为尿和气。五脏六腑中，心是主宰，耳是听者，目是观察者，肺是宰相，肝是将领，脾是卫士，肾是主外的官。（肾是作强的官员，《师传篇》说：肾主司外，使人远听视，耳好恶，以知晓其本性。）所以五脏六腑的津液，都向上渗入眼睛。心中悲伤气机并聚则心系紧急，心系紧急则肺叶上举，肺叶上举则津液上溢。心和肺不能经常上举，忽上忽下，所以咳嗽且流泪。体内热则胃中消化谷物快，消化谷物快则虫上下活动，肠胃充满扩张。（宽意，指肠胃扩张。）所以胃缓，胃缓则气逆，所以吐出唾液。（出自《五癃津液别论》）
【素问】问不知道泪是从哪里产生的，鼻涕是从哪里出来的。回答说：心是五脏的精气专聚之处。（五脏各有其精，而心专门统领它。）眼睛，是心的窍。（眼虽然是肝窍，但能辨别事物，所以又是心窍。）华彩光泽是心的荣润表现。所以人有德行，气和就表现在眼中，如果有缺失，忧愁就表现在面色上。所以悲哀就会流泪。流泪的水是怎么产生的呢？水的根源，是积水。积水，是至阴。至阴，是肾的精气。宗精之水之所以不流出，是因为精气固持它，辅助包裹它，所以水不流动。水的精华是志，火的精华是神，水火相互感应，神志都悲哀，所以眼中出水。所以谚语说：心悲叫做志悲。志与心精，共同汇聚于眼睛。涕和泪来源于脑。脑是阴，髓是骨的充实部分。所以脑渗液为涕。志是骨的主宰，所以水流而涕随之，它们的运行类似。（脑为髓海，与肾相通。）如果哭不出泪，说明哭得不悲伤。不流泪，说明神不慈爱。神不慈爱则志不悲伤，阴阳相互持衡，泪怎么能独自到来呢？志悲伤则内心郁结，郁结则冲击阴分，冲击阴分则志离开眼睛，志离开则神不能守住精气，精神离开眼睛，涕泪就出来了。况且你难道没读过经文吗？厥证时眼睛看不见东西。人发生厥证时，阳气并并于上部，阴气并并于下部。阳并于上则火独光，阴并于下则脚冷且腹胀。一水不能胜五火。（五脏之火。）所以眼睛失明。因此迎着大风流泪不止。风侵袭眼睛时，阳气内守于精，这是火气燔灼眼睛，所以见风就流泪。（内有火气，外冲于风。）火疾风生才能下雨，这是同类相求的道理。（出自《解精微论》）
【灵枢】女人没有胡须，是没有血气吗？回答说：冲脉和任脉都起于胞中，向上沿着脊背里面。（这里又说冲任行于背部，按《素问·骨空论》说，任脉循腹里，上关元，冲脉挟脐，上行至胸中而散，督脉贯脊。然而这三脉同源，经文多有交错言说的情况。）它们是经络之海。其中浮行于体表的，沿着腹部右侧上行，会合于咽喉，分支联络唇口。血气盛则充养皮肤，温热肌肉；血特别盛则淡渗皮肤，生出毫毛。现在女人天生，气有余而血不足，因为经常失血脱泄的缘故。冲任二脉不能荣润口唇，所以胡须不生。士人中有人损伤了阴器，阴气绝而不勃起，但是他的胡须不去掉。宦官唯独胡须去掉，为什么呢？回答说：宦官割去了宗筋（阴器），损伤了冲脉，血液泻出不能再恢复，皮肤内部结滞，口唇不得荣润，所以胡须不生。那种天生没有胡须的人（天生阳气不举，不能御妇），未曾受过伤害，也没有失血，但是他的胡须不生，这是什么原因呢？回答说：这是先天禀赋不足。他的任冲二脉不盛，宗筋不成形，有气无血，口唇不得荣润，所以胡须不生。（出自《五音五味篇》）
[Su Wen] In ancient times, those who understood the Way of life modeled themselves on Yin and Yang and harmonized with appropriate methods of cultivation. They regulated their diet and drinking, maintained regular daily routines, and did not engage in reckless exertion. Thus, they could maintain the unity of form (physical body) and spirit (Shen). (When the spirit departs from the form, death occurs.) Consequently, they fulfilled their natural lifespan, living to be over a hundred years old before passing away. People today are different. They treat wine as if it were water, make recklessness a habit, engage in sexual intercourse while drunk, exhaust their essence (Jing) through desire, and dissipate their true Qi (Zhen Qi). They do not know how to maintain fullness (maintaining fullness implies the fear of depletion). They fail to regulate their spirit at appropriate times, seeking only momentary pleasure, thereby going against the joy of life preservation (indulging in desires goes against the joy of nourishing life). Their daily routines are irregular, so they begin to decline by the age of fifty. The sages of antiquity taught the people, saying one should avoid empty evils (Xu Xie) and thieving winds (Zei Feng) at the proper times. With a tranquil and empty mind, True Qi follows. (This corresponds to the meaning in Laozi's philosophy: within the indistinct there is an image, within the profound darkness there is essence.) Spirit remains inwardly guarded; how could disease arise? When girls reach seven years old (Wang Bing's commentary: The number of Old Yang ends at nine. Girls belong to Young Yin, so the number of Young Yang is combined with it), Kidney Qi becomes abundant, teeth change, and hair grows. (The Kidneys govern bones and are the reservoir of essence and blood. Teeth are the surplus of bones, and hair is the surplus of blood.) At fourteen (two sevens), Tian Gui arrives (Menstrual blood belongs to the North, Ren and Gui waters). The Ren Mai (Conception Vessel) becomes unobstructed, and the Chong Mai (Penetrating Vessel) becomes abundant. Menstruation arrives regularly, enabling conception. (The Chong Mai is the Sea of Blood, and the Ren Mai governs pregnancy. These two vessels support each other, enabling reproduction. Menstrual blood comes once a month with a constant rhythm, hence called Jing Shui or Yue Shui. Delay indicates pathology. In men, when the Chong and Ren vessels are abundant, Qi nourishes upward to produce facial hair; in women, when abundant, it flows downward to produce menstruation, hence no beard.) At twenty-one (three sevens), Kidney Qi is balanced, wisdom teeth grow, and physical growth reaches its peak. (The last teeth to emerge mark the point where bodily height ceases to increase.) At twenty-eight (four sevens), sinews and bones are firm, hair reaches its maximum length, and the body is strong and vigorous. At thirty-five (five sevens), the Yangming Meridian begins to decline, the face starts to wither, and hair begins to fall. (The Foot-Yangming Stomach Meridian originates at the nose, crosses the nasal root, descends along the lateral nose, enters the upper gums, emerges around the lips, meets at Chengjiang, goes behind the jaw to Daying, follows the cheekbone, ascends in front of the ear, passes through Guest Master, follows the hairline to the forehead. The Hand-Yangming Large Intestine Meridian ascends the neck, passes through the cheek, enters the lower gums, emerges around the lips. Both meridians nourish the face; their decline causes facial withering and hair loss.) At forty-two (six sevens), the Three Yang meridians decline above, the face completely withers, and hair begins to turn white. (The Three Yang meridians all ascend to the head and face.) At forty-nine (seven sevens), the Ren Mai becomes deficient, the Chong Mai declines, Tian Gui exhausts, and the earthly pathway (menstruation) stops. (Menstruation ceases here.) Thus, the form deteriorates and reproduction is impossible. (Women have excess Qi but deficient Blood due to frequent depletion.) Boys reach eight years old (Wang Bing's commentary: The number of Old Yin ends at ten. Boys belong to Young Yang, so the number of Young Yin is combined with it. The I Ching says: Heaven is nine, Earth is ten, which refers to this number). Kidney Qi becomes solid, hair grows, and teeth change. At sixteen (two eights), Kidney Qi is abundant, Tian Gui arrives (Yang Essence), essence overflows and is emitted, Yin and Yang harmonize, enabling conception. At twenty-four (three eights), Kidney Qi is balanced, sinews and bones are strong, wisdom teeth grow, and growth peaks. At thirty-two (four eights), sinews and bones are robust, muscles are full and strong. At forty (five eights), Kidney Qi declines, hair falls, and teeth become dry. At forty-eight (six eights), Yang Qi衰竭 (exhausts) above, the face withers, and temples turn gray. At fifty-six (seven eights), Liver Qi declines, sinews cannot move freely, Tian Gui exhausts, essence diminishes, Kidney Qi declines, and the body reaches extremity. At sixty-four (eight eights), teeth and hair fall out (the hexagram qi is exhausted). The Kidneys govern Water and receive the essence of the Six Fu and Five Zang organs to store it. Thus, only when the Five Zang are abundant can they excrete. Now that all Five Zang are declining, sinews and bones are loose, Tian Gui is gone, temples are white, the body feels heavy, gait is unsteady, and reproduction is impossible. Why do some elderly people still have children? This is because their innate longevity exceeds normal limits, their Qi and meridians remain open, and Kidney Qi is sufficient. Although they may conceive, men do not exceed the limit of eight eights (64), and women do not exceed the limit of seven sevens (49); the essence and Qi of Heaven and Earth are exhausted. (Wang Bing's commentary: The lifespan for procreation does not exceed these numbers. Ma Yun's view is incorrect.) (From *Shanggu Tianzhen Lun*)
[Su Wen] The three months of Spring are called "Fa Chen" (releasing the old and generating the new). Heaven and Earth generate together, and all things flourish. (Heaven and Earth interact, allowing all things to thrive.) Sleep late and rise early, take broad steps in the courtyard, let hair hang loose and relax the body, to allow the will to generate. Promote growth without killing, give without taking, reward without punishing. This responds to the Qi of Spring and is the way of nourishing life. Violating it injures the Liver, leading to cold transformations in Summer, reducing the resources for supporting Summer's growth. (Fire is the child of Wood; cold transformation means Wood cannot generate Fire, failing to support Summer's command.) The three months of Summer are called "Fan Xiu" (luxuriant beauty). Heaven and Earth Qi intersect, and all things flower and bear fruit. Sleep late and rise early, do not dislike the sun. (Dislike means satisfaction; do not stay out too long in the midday sun to avoid heatstroke, opposite to waiting for sunlight in Winter.) Keep the will free from anger, allow brilliance to mature, allow Qi to vent, as if loving what is outside. (Following Yang which governs the exterior.) This responds to the Qi of Summer and is the way of nourishing growth. Violating it injures the Heart, leading to malaria in Autumn, reducing resources for supporting Autumn's harvest. (No Qi to support Autumn's gathering command.) Severe illness occurs at Winter Solstice. (Water overcomes Fire.) The three months of Autumn are called "Rong Ping" (appearance and state are level/stable). Heaven's Qi becomes urgent, Earth's Qi becomes clear. Sleep early and rise early, waking with the chickens. Keep the will peaceful to slow the punishment of Autumn Qi, gather and store Shen Qi, keep Autumn Qi balanced. Do not let the will stray outward, keeping Lung Qi pure. This responds to the Qi of Autumn and is the way of nourishing harvesting. Violating it injures the Lungs, leading to undigested diarrhea in Winter, reducing resources for supporting Winter's storage. (No Qi to support Winter's storing command.) The three months of Winter are called "Bi Cang" (closing and storing). Water freezes, earth cracks. Do not disturb Yang. (Yang Qi hides internally.) Sleep early and rise late, waiting for sunlight. Let Qi be latent and hidden, as if having private intentions, as if already possessing something. (Opposite to Summer.) Avoid cold and seek warmth, do not sweat through the skin, preventing frequent loss of Qi. (Warning against reckless sweating which depletes Yang Qi.) This responds to the Qi of Winter and is the way of nourishing storage. Violating it injures the Kidneys, leading to flaccidity and cold limbs in Spring, reducing resources for supporting Spring's generation. (No Qi to support Spring's generating command.) (From *Siqi Tiaoshen Dalun*)
[Su Wen] Heaven nourishes humans with Five Qi. (Wu Kun's commentary: Five Qi are not just the five odors—pungent, scorched, fragrant, putrid, fishy—but Wind, Cold, Summer-heat, Dampness, and Dryness, which govern the Five Zang respectively. If received without excess or harm, they all nourish humans.) Earth nourishes humans with Five Flavors. Five Qi enter the nose. (The nose receives formless Heavenly Qi.) Stored in Heart and Lung, they cause the complexion to be bright and the voice to be resonant. (Heart governs complexion, Lung governs voice.) Five Flavors enter the mouth. (The mouth receives terrestrial Qi with form.) Stored in intestines and stomach, flavors are stored to nourish Five Qi. When Qi is harmonious, life arises; fluids and liquids form mutually, and Shen naturally generates. (Accumulating Jing generates Shen.) (From *Liujie Zangxiang Lun*)
[Ling Shu] Food and drink enter the mouth and are transported to the intestines and stomach. Their fluids differentiate into five types. In cold weather with thin clothing, urine and Qi are produced. (Urine first, then Qi.) In hot weather with thick clothing, sweat is produced. In sorrow, Qi gathers to produce tears. Internal heat and relaxed stomach produce saliva. Internal reversal of pathogenic Qi blocks Qi flow, causing water swelling. I wish to hear the principle. The answer is: Food and drink enter the mouth, flavors are five, each pouring into its respective sea. (Distributing to the Five Zang.) Jin Ye (fluids) each follow their paths. Thus, San Jiao emits Qi. (Zong Qi emerges from Upper Jiao, Ying Qi from Middle Jiao, Wei Qi from Lower Jiao.) To warm muscles and fill skin, becoming Jin. Flowing without stopping is Ye. Hot weather and thick clothing open pores, causing sweat. Cold staying between muscle intervals condenses into foam, causing pain. Cold weather closes pores, Qi and dampness do not move. (Not moving on the surface, so it flows down as urine.) Water flows down to the Bladder to become urine and Qi. Among the Five Zang and Six Fu, the Heart is the master, the Ear is the listener, the Eye is the observer, the Lung is the minister, the Liver is the general, the Spleen is the guard, and the Kidney is the external manager. (Kidney is the official of strength. *Shichuan Pian* says: Kidney governs externals, enabling distant hearing and vision, discerning likes and dislikes through ears.) Thus, fluids from all Five Zang and Six Fu seep upward into the eyes. Sadness gathers Qi, making the Heart Tie tense. Tense Heart Tie lifts the Lung. Lifted Lung causes fluid to overflow upward. Since Heart Tie and Lung cannot always lift, rising and falling suddenly causes coughing and tearing. Internal heat digests grain quickly; quick digestion causes worms to move up and down, filling the intestines and stomach (expanding them). Thus, the stomach relaxes. Relaxed stomach causes Qi rebellion, producing saliva. (From *Wulong Jin Ye Bie Lun*)
[Su Wen] Asking where tears and nasal discharge originate. The answer is: The Heart is the specialized essence of the Five Zang. (Each Zang has its essence, but the Heart specializes in it.) The eye is its orifice. (Although the eye is the orifice of the Liver, it distinguishes objects, so it is also the orifice of the Heart.) Luster and color are its flourishing manifestation. Therefore, when a person has virtue, Qi harmonizes in the eye; if lacking, worry shows in color. Thus, sorrow causes tears. Where does the water of tears come from? The source of water is accumulated water. Accumulated water is Extreme Yin. Extreme Yin is the essence of the Kidney. The water of Zong Jing does not flow out because Jing holds it, assists it, and wraps it, so water does not move. The essence of Water is Zhi (Will), and the essence of Fire is Shen (Spirit). Water and Fire interact; when Shen and Zhi are both sorrowful, water emerges from the eyes. Hence the proverb: Heart sorrow is called Will sorrow. Zhi and Heart essence gather at the eye. Nasal discharge and tears come from the Brain. The Brain is Yin; Marrow fills the bones. Thus, Brain渗 (seeps) to become nasal discharge. Zhi is the master of bone, so water flows and nasal discharge follows, similar in movement. (Brain is the Sea of Marrow, communicating with Kidney.) If crying produces no tears, the cry is not sorrowful. No tears mean Shen is not compassionate. If Shen is not compassionate, Zhi is not sorrowful. Yin and Yang hold each other; how can tears come alone? Sorrowful Zhi causes depression, depressing attacks Yin. Attacking Yin drives Zhi away from the eye. When Zhi leaves, Shen does not guard Jing. When Spirit and Essence leave the eye, tears and nasal discharge occur. Have you not read the classics? In Jue syndrome, the eyes see nothing. In Jue syndrome, Yang Qi merges upward, Yin Qi merges downward. Yang merging upward makes Fire shine alone; Yin merging downward causes cold feet and distension. One Water cannot overcome Five Fires. (Fire of the Five Zang.) Thus, the eyes go blind. Therefore, facing wind causes continuous tearing. When wind strikes the eye, Yang Qi guards internally in Jing; this is Fire Qi burning the eye, so wind causes tearing. (Internal Fire Qi rushes outward against Wind.) Rapid fire and generated wind can produce rain; this is the principle of similarity. (From *Jiejingwei Lun*)
[Ling Shu] Do women lack Beard Hair because they lack Blood and Qi? The answer is: The Chong Mai and Ren Mai both originate in the Bao Zhong (uterus/center), ascending along the interior of the back. (Here it states Chong and Ren travel the back; according to *Su Wen Gu Kong Lun*, Ren Mai travels the abdominal interior to Guanyuan, Chong Mai flanks the navel ascending to the chest to disperse, and Du Mai pierces the spine. However, these three vessels share a source, and the text often intersects in description.) They are the Sea of Meridians. Those floating externally travel up the right abdomen, meeting at the throat, branching to connect the lips and mouth. Abundant Blood and Qi fill the skin and warm flesh; abundant Blood alone渗 (seeps) into skin, generating fine hair. Women are born with excess Qi but deficient Blood due to frequent blood loss. The Chong and Ren vessels do not nourish the lips and mouth, so beard hair does not grow. Scholars who injure their Yin organ, causing Yin Qi to cease and not rise, yet retain their beard hair. Eunuchs lose theirs. Why? The answer is: Eunuchs remove the Zong Jin (genitals), injuring the Chong Mai. Blood drains and does not return, internal skin结 (knots), lips and mouth are not nourished, so beard hair does not grow. Those born without beard hair (innate Yang Qi does not rise, unable to engage in intercourse), never injured, not depleted of blood, yet do not grow beard hair. Why? The answer is: This is innate insufficiency. Their Ren and Chong vessels are not abundant, Zong Jin does not form, having Qi but no Blood, lips and mouth are not nourished, so beard hair does not grow. (From *Wuyin Wuwei Pian*)
