汉东王先生《家宝》论五脏相生刑克∶
肝属东方木，木生火，金能克之，旺在春三个月，能克于土，见秋而衰。以脾为妇，木为阳。脾为阴也。
心属南方火，火生土，水能克之，旺在夏三个月，能克于金，见冬而衰。脾为中宫土，土生金，木能克之，旺
在四季月，四立前后各十八日，能克于水。三月、六月、九月、十二月亦是旺也。肺属西方金，金生水，火能
克之，旺在秋三个月，见春而衰，能克于木。肾属北方水，水生木，土能克之，旺在冬三个月，见夏而衰，能克于火。
所言肝属木，肺属金。肝却见水沉，肺却见水浮者何也？肝者，谓水所生，又行其阴道，被水土所荫，故
见水而沉，及至煮熟还其本性，却又浮也；其肺属金，所谓心之相近，又行其阳道，所以被火抽，见水灌虚浮，
及至煮熟复还本性，而却沉矣。
茅先生论小儿心脏不宜夏∶
久泻变为痢，泻血即难当。形瘦不行坐，心绝生口疮。若逢如此病，端是应南方。若向其中得，何须更忖量。
小儿肝脏不宜春∶
眼爱频频涩，浑身似醉人。时时贪睡卧，心烦美好嗔。唇白眼胞肿，狂言不欲闻。东方应春候，此病不宜春。
小儿脾脏不宜四季∶
面爱常黄好，不可见相传。体差增寒热，行难少食餐。此病忌四季。脚面肿相连。朝来阴肿了，不久在人间。
小儿肺脏不宜秋∶
行后气常急，胀满似怀身。项直时时喘，乳食口不侵。积聚成虚气，惊多癖结成。秋问逢此候，一命定难生。
小儿肾脏不宜冬∶
痰汗时时有，尿多夜夜惊。遍身生粟疥，手足冷如冰。口内虫常出，面黑绝精神。应此北方候，冬得损其身。
肝归属于东方，五行属木。木能生火，金能克制木。肝气在春季三个月最为旺盛，能够克制脾土，但到了秋季就会衰退。以脾脏比喻为妻子，肝脏属阳，脾脏属阴。
心脏归属于南方，五行属火。火能生土，水能克制火。心气在夏季三个月最为旺盛，能够克制肺金，但到了冬季就会衰退。脾脏位于中央，五行属土。土能生金，木能克制土。脾气在四季的最后一个月（即每季末月）最为旺盛，具体是在立春、立夏、立秋、立冬这四个节气前后各十八天，此外三月、六月、九月、十二月也是脾气旺盛之时。脾气能够克制肾水。
肺脏归属于西方，五行属金。金能生水，火能克制金。肺气在秋季三个月最为旺盛，到了春季就会衰退，同时肺金能够克制肝木。
肾脏归属于北方，五行属水。水能生木，土能克制水。肾气在冬季三个月最为旺盛，到了夏季就会衰退，同时肾水能够克制心火。
文中提到肝属木，肺属金。为什么肝遇到水会下沉，而肺遇到水会上浮呢？肝脏被认为是由水所生（水生木），且运行于阴经，受到水土的荫蔽，所以见到水就下沉；等到煮熟之后，恢复其本性，反而会上浮。肺脏属于金，所谓“心之相近”（指肺位最高，覆盖于心之上，或指金与水之关系中的特定语境，此处依原文直译并保留逻辑），且运行于阳经，所以被火所耗散，见到水时因为空虚而上浮；等到煮熟之后，恢复其本性，反而下沉了。
如果久泻转变为痢疾，泻下血便就难以承受。身体消瘦无法行走坐立，这是心气绝的表现，口中会出现疮疡。如果遇到这样的病症，确实对应南方的火运。如果在夏季中心脏受邪，就不必再犹豫揣测了。
小儿的肝脏不宜在春季患病：
眼睛经常感到干涩，浑身像喝醉的人一样。时时贪睡卧倒，心中烦躁容易发怒。嘴唇发白，眼睑肿胀，胡言乱语不想听。这对应东方的春令，这种病不适合发生在春季。
小儿的脾脏不宜在四季末月患病：
面色常常发黄，病情不可轻视传变。体质虚弱，寒热交替，行走困难，食欲减退。这种病忌讳在四季发生。脚面肿胀相连。早晨起来阴部肿胀，不久将危及生命。
小儿的肺脏不宜在秋季患病：
行走后气息急促，腹部胀满好像怀孕一样。颈部僵硬，时时气喘，吃奶进食时口不开或不进。积聚形成虚气，惊恐多，癖块结成。在秋季遇到这种征候，性命注定难保。
小儿的肾脏不宜在冬季患病：
痰液和汗水时不时出现，尿多，夜夜惊悸。全身长出粟粒状的疥疮，手脚冷得像冰一样。口中常有虫状物吐出，面色黑灰，精神全无。这对应北方的冬令，冬季得了这种病会损害身体。
In Mr. Wang of Handong's *Jiabao* (Family Treasure), the generation and restriction relationships among the Five Zang Organs are discussed:
The Liver belongs to the East, corresponding to Wood in the Five Elements. Wood generates Fire, and Metal restricts Wood. Liver Qi is most prosperous during the three months of Spring. It can restrict Spleen Earth but declines in Autumn. Taking the Spleen as the "wife," the Liver is Yang, while the Spleen is Yin.
The Heart belongs to the South, corresponding to Fire. Fire generates Earth, and Water restricts Fire. Heart Qi is most prosperous during the three months of Summer. It can restrict Lung Metal but declines in Winter. The Spleen resides in the Central Palace, corresponding to Earth. Earth generates Metal, and Wood restricts Earth. Spleen Qi is most prosperous during the last month of each season (the four seasons' transition months), specifically eighteen days before and after the Start of Spring, Start of Summer, Start of Autumn, and Start of Winter. Additionally, the third, sixth, ninth, and twelfth lunar months are also times when Spleen Qi is prosperous. Spleen Earth can restrict Kidney Water.
The Lungs belong to the West, corresponding to Metal. Metal generates Water, and Fire restricts Metal. Lung Qi is most prosperous during the three months of Autumn, declines in Spring, and can restrict Liver Wood.
The Kidneys belong to the North, corresponding to Water. Water generates Wood, and Earth restricts Water. Kidney Qi is most prosperous during the three months of Winter, declines in Summer, and can restrict Heart Fire.
The text states that the Liver corresponds to Wood and the Lungs to Metal. Why does the Liver sink when encountering water, while the Lungs float? The Liver is said to be generated by Water (Water generates Wood) and operates through the Yin meridians, being shaded by Water and Earth; thus, it sinks upon encountering water. However, after being cooked, it returns to its original nature and floats. The Lungs correspond to Metal. Referring to their proximity to the Heart (or specific elemental interactions) and their operation through the Yang pathways, they are depleted by Fire. Upon encountering water, due to emptiness, they float. After being cooked, they return to their original nature and sink.
Mr. Mao discusses why a child's Heart should not suffer disease in Summer:
Prolonged diarrhea transforming into dysentery, with bloody stools, becomes difficult to manage. The body becomes emaciated, unable to walk or sit; this indicates Heart Qi exhaustion, accompanied by mouth ulcers. If such symptoms appear, it indeed corresponds to the Southern Fire influence. If the Heart is affected during this time, there is no need for further hesitation.
A child's Liver should not suffer disease in Spring:
The eyes frequently feel dry and gritty; the whole body feels like that of a drunk person. There is constant drowsiness and lying down; mental restlessness and irritability occur easily. The lips turn white, and the eyelids swell. Delirious speech is heard, which one wishes not to hear. This corresponds to the Eastern Spring climate; such illness is unfavorable in Spring.
A child's Spleen should not suffer disease in the transition months of the Four Seasons:
The face often appears yellow; the condition must not be ignored or allowed to spread. The physique deteriorates with alternating chills and fever; walking is difficult, and food intake is reduced. This illness is taboo during the seasonal transitions. Swelling connects across the insteps. Morning swelling of the genitalia indicates death is imminent.
A child's Lungs should not suffer disease in Autumn:
After walking, breathing is often rapid; abdominal distension resembles pregnancy. The neck is stiff, and wheezing occurs frequently; milk and food are refused or not taken into the mouth. Accumulations form empty Qi; frequent fright leads to the formation of masses. Encountering this syndrome in Autumn means life is unlikely to be saved.
A child's Kidneys should not suffer disease in Winter:
Phlegm and sweat appear intermittently; urination is frequent, and night terrors occur nightly. The entire body develops millet-sized scabies; hands and feet are cold as ice. Worm-like substances frequently emerge from the mouth; the complexion is black, and spirit is completely exhausted. This corresponds to the Northern Winter climate; contracting this in Winter damages the body.
