黄帝问于少俞曰。有人于此。并行并立。其年之长少等也。衣之浓薄均也。卒然遇烈风豪雨。或病。或不病。或皆
病。或皆不病。其故何也。少俞曰。帝问何急。黄帝曰。愿尽闻之。少俞曰。春青风。夏阳风。秋凉风。冬寒风。凡此
四时之风者。其所病各不同形。黄帝曰。四时之风。病患如何。少俞曰。黄色薄皮弱肉者。不胜春之虚风。白色薄皮弱
肉者。不胜夏之虚风。青色薄皮弱肉。不胜秋之虚风。赤色薄皮弱肉。不胜冬之虚风也。黄帝曰。黑色不病乎。少俞曰。
黑色而皮浓肉坚。固不伤于四时之风。其皮薄而肉不坚。色不一者。长夏至而有虚风者病矣。其皮浓而肌肉坚者。长夏
至而有虚风。不病也。其皮浓而肌肉坚者。必重感于寒外内皆然。乃病。黄帝曰。善。黄帝曰。夫人之忍痛与不忍痛者。
非勇怯之分也。夫勇士之不忍痛者。见难则前。见痛则止。夫怯士之忍痛者。闻难则恐。遇痛不动。夫勇士之忍痛者。
见难不恐。遇痛不动。夫怯士之不忍痛者。见难与痛。目转面 。恐不能言。失气惊。（句有脱字）颜色变化。乍死乍生。
余见其然也。不知其何由。愿闻其故。少俞曰。夫忍痛与不忍痛者。皮肤之薄浓。肌肉之坚脆缓急之分也。非勇怯之谓
也。黄帝曰。愿闻勇怯之所由然。少俞曰。勇士者。目深以固。长冲直扬。三焦理横。其心端直。其肝大以坚。其胆满
以傍。怒则气盛而胸张。肝举而胆横。 裂而目扬。毛起而面苍。此勇士之所由然者也。黄帝曰。愿闻怯士之所由然。
少俞曰。怯士者。目大而不减。阴阳相失。其焦理纵。 KT 短而小。肝系缓其胆不满。而纵肠胃挺。胁下空。虽方大
怒气不能满其胸。肝肺虽举。气衰复下。故不能久怒。此怯士之所由然者也。黄帝曰。怯士之得酒。怒不避勇士者。何
脏使然。少俞曰。酒者水谷之精。熟谷之液也。其气 悍。其入于胃中。则胃胀。气上逆满于胸中肝浮胆横。当是之时。
固比于勇士。气衰则悔。与勇士同类。不知避之。名曰酒悖也。
前后两截不续。前论五色之人。后论勇怯之性。前论外邪之伤。后论中情之变。笔致醒快生动可喜。
黄帝向少俞问道：这里有个人，和别人一起行走、一起站立，年龄大小相同，穿衣的厚薄也一致。突然遇到狂风暴雨，有的人生病，有的人不生病；有的人都生病，有的人都不生病。这是什么原因呢？
少俞说：陛下问得多么急切啊。
黄帝说：我希望详尽地听您讲解。
少俞说：春季的青风，夏季的阳风，秋季的凉风，冬季的寒风，这四季的风邪，所导致的病症形态各不相同。
黄帝说：四季的风邪致病情况是怎样的？
少俞说：肤色黄、皮肤薄、肌肉软弱的人，不能耐受春季的虚风；肤色白、皮肤薄、肌肉软弱的人，不能耐受夏季的虚风；肤色青、皮肤薄、肌肉软弱的人，不能耐受秋季的虚风；肤色赤、皮肤薄、肌肉软弱的人，不能耐受冬季的虚风。
黄帝说：肤色黑的人就不生病吗？
少俞说：肤色黑且皮肤厚实、肌肉坚实的人，确实不会受四季风邪的伤害。如果皮肤薄而肌肉不坚实，且面色不均匀的，在长夏时节遇到虚风就会生病。如果皮肤厚实且肌肉坚实的人，在长夏时节遇到虚风，就不会生病。但是，如果皮肤厚实且肌肉坚实的人，必定是再次感受寒邪，内外皆受寒邪侵袭，才会生病。
黄帝说：好。
黄帝又问：人忍受疼痛和不忍受疼痛的区别，并不是勇敢和怯懦的分野。那些勇敢的但忍受不了疼痛的人，见到危难就上前，见到疼痛就停止；那些怯懦的但能忍受疼痛的人，听到危难就恐惧，遇到疼痛却不动声色；那些勇敢的也能忍受疼痛的人，见到危难不恐惧，遇到疼痛也不动声色；那些怯懦的也不能忍受疼痛的人，见到危难和疼痛，眼睛转动、脸色改变，恐惧得说不出话，气机下陷惊骇（此处原文有脱漏），脸色变化不定，忽死忽生。我见过这种情况，但不知道是什么原因造成的，希望听听其中的道理。
少俞说：忍受疼痛与不忍受疼痛的区别，在于皮肤的厚薄、肌肉的坚脆以及筋脉的松弛或紧张的不同，这并不是指勇敢和怯懦。
黄帝说：我希望听听勇敢和怯懦产生的原因。
少俞说：勇敢的人，目光深邃而坚定，眉宇间气势昂扬，三焦的纹理是横行的，心脏端正直立，肝脏大而坚实，胆囊饱满且扩张。发怒时，气机旺盛而胸廓张开，肝气升举而胆气横溢，眼裂张大而目光上扬，汗毛竖起而面色苍劲。这就是勇敢的人之所以如此的原因。
黄帝说：我希望听听怯懦的人之所以如此的原因。
少俞说：怯懦的人，眼睛大但不收敛，阴阳之气失调，三焦的纹理是纵行的，膈膜短小，肝系松弛，胆囊不满且下垂，肠胃挺直，胁下空虚。即使大发怒气，也不能使胸中气满。虽然肝肺之气暂时升举，但很快气衰而下沉，所以不能长久愤怒。这就是怯懦的人之所以如此的原因。
黄帝说：怯懦的人喝了酒之后，发怒时不躲避勇士，这是哪个脏腑的作用呢？
少俞说：酒是水谷的精微，是熟谷的液汁。它的气性剽悍滑利。当它进入胃中，会使胃胀满，气机上逆充满于胸中，导致肝气上浮、胆气横溢。在这个时候，人的状态确实比得上勇士。但酒气衰退后就会后悔，行为与勇士同类，不知道回避危险，这叫做“酒悖”（酒后失态）。
这段文字前后两部分衔接不紧密。前一部分论述不同肤色之人的体质差异，后一部分论述勇敢与怯懦的性格成因。前一部分论述外邪对人体的伤害，后一部分论述内在情志的变化。文笔清醒明快，生动可喜。
Huangdi asked Shaoyu, saying: "There is a person here who walks and stands alongside others. Their ages are equal, and the thickness of their clothing is uniform. Suddenly encountering fierce winds and heavy rains, some fall ill while others do not; some all fall ill, while others none fall ill. What is the reason for this?"
Shaoyu replied, "Why does Your Majesty ask so urgently?"
Huangdi said, "I wish to hear it in full detail."
Shaoyu said, "The green wind of spring, the yang wind of summer, the cool wind of autumn, and the cold wind of winter. These four seasonal winds cause diseases with different manifestations."
Huangdi asked, "How do the seasonal winds cause disease?"
Shaoyu said, "Those with yellow complexion, thin skin, and weak flesh cannot withstand the deficient wind of spring. Those with white complexion, thin skin, and weak flesh cannot withstand the deficient wind of summer. Those with bluish complexion, thin skin, and weak flesh cannot withstand the deficient wind of autumn. Those with reddish complexion, thin skin, and weak flesh cannot withstand the deficient wind of winter."
Huangdi asked, "Do those with black complexion not get sick?"
Shaoyu said, "Those with black complexion, thick skin, and firm flesh certainly will not be injured by the winds of the four seasons. However, those with thin skin, unfirm flesh, and uneven complexion will fall ill when exposed to deficient wind during late summer. Those with thick skin and firm flesh will not fall ill when exposed to deficient wind during late summer. But if those with thick skin and firm flesh are heavily affected by cold, both internally and externally, then they will fall ill."
Huangdi said, "Excellent."
Huangdi continued, "The ability to endure pain or not is not the distinction between courage and cowardice. A courageous person who cannot endure pain will advance when facing danger but stop when feeling pain. A cowardly person who can endure pain will fear upon hearing of danger but remain motionless when experiencing pain. A courageous person who can endure pain will not fear danger nor remain motionless when experiencing pain. A cowardly person who cannot endure pain, upon seeing danger and pain, will have rolling eyes and changing facial expressions, be too fearful to speak, suffer from Qi sinking and shock (there are missing characters in the original text), experience fluctuating complexions, appearing as if dead one moment and alive the next. I have seen such phenomena but do not know the cause. I wish to hear the explanation."
Shaoyu said, "The difference between enduring pain and not enduring pain lies in the thickness of the skin, the firmness or fragility of the muscle, and the tension or laxity of the tendons. This is not what is meant by courage and cowardice."
Huangdi said, "I wish to hear the origin of courage and cowardice."
Shaoyu said, "A courageous person has deep and fixed eyes, straight and upward-looking eyebrows, horizontal Sanjiao (Triple Burner) texture, an upright heart, a large and firm liver, and a full and expanded gallbladder. When angry, Qi becomes abundant and the chest expands; the Liver Qi rises and the Gallbladder Qi spreads horizontally; the eye fissures widen and the gaze lifts; hair stands on end and the face turns pale/cyan. This is the origin of the courageous person's nature."
Huangdi said, "I wish to hear the origin of the cowardly person's nature."
Shaoyu said, "A cowardly person has large but unfocused eyes, with Yin and Yang Qi out of balance. The Sanjiao texture is vertical, the diaphragm is short and small, the liver ligaments are lax, the gallbladder is not full and hangs low, the intestines and stomach are straight, and the hypochondrium is empty. Even when extremely angry, the chest cannot become full. Although Liver and Lung Qi may rise temporarily, Qi declines and sinks back down quickly, so they cannot maintain anger for long. This is the origin of the cowardly person's nature."
Huangdi asked, "When a cowardly person drinks wine, why do they become angry without avoiding courageous persons? Which Zang-Organ causes this?"
Shaoyu said, "Wine is the essence of water and grain, the liquid of cooked grains. Its Qi is fierce and penetrating. Upon entering the stomach, it causes stomach distension, and Qi rebels upward, filling the chest. This causes Liver Qi to float and Gallbladder Qi to spread horizontally. At this time, one is indeed comparable to a courageous person. However, once the Qi subsides, regret follows. Their behavior becomes similar to that of a courageous person, yet they fail to avoid danger. This is called 'Jiu Bei' (wine-induced recklessness)."
The two preceding sections are not continuous. The first part discusses people of five colors, while the second part discusses the nature of courage and cowardice. The first part discusses injury by external pathogens, while the second part discusses changes in internal emotions. The writing style is clear, lively, and pleasing.
