《圣济经》原化篇·凝形殊禀章曰∶天地者，形之大也；阴阳者，气之大也。惟形与气相资而立，未始偏废，
男女合精，万物化生，天地阴阳之形气寓焉。语七八之数，七少阳也，八少阴也，相感而流通。故女子二七天
癸至，男子二八天癸至，则以阴阳交合而兆始。语九十之数，九老阳也，十老阴也，相包而赋形。故阴穷于十，
男能围之；阳穷于九，女能方之，则以阴阳相生而成终故也。元气孕育，皆始于子。自子推之，男左旋，积岁
三十而至已；女右旋，积岁二十而至已。已为正阳，阴实从之。自已怀妊，男左旋十月，儿生于寅；女右旋十
月而生于申。申为三阴，寅为三阳，而生育之时着矣。其禀赋也，体有刚柔，脉有强弱，气有多寡，血有盛衰，
皆一定而不易也。以至分野异域，则所产有多寡之宜。吉事有祥，则所梦各应其类。是故荆、扬薄壤多女，雍、
翼浓壤多男。熊、罴为男子之祥，虺、蛇为女子之祥，是皆理之可推也。胎化之法，有所谓转女为男者，亦皆
理之自然。如食牡鸡，取阳精之全于天产者。带雄黄，取阳精之全于地产者。操弓矢，籍斧斤，取刚物之见于
人事者。气类潜通，造化密移，必于三月兆形之先，盖方仪则未具，阳可以胜阴，变女为男，理固然也。
杨大邺《童子秘诀》∶小儿十月养胎，触忌克罚。
第一月妊娠，胎月本于肝脏，主养魂魄，故此月宜多吃酸物，以助目也，自然一脏强盛也。物味辛辣，缘
肺纳辛，主于金克木，恐伤于肝。第二个月亦然，何也？缘少阳脉养胆也，肝合故也。第三个月，肺脏主养心

主火，火克金故也。第四个月，心脏主于养肾，此月宜加增于焦，以助火也。缘心主于火，其脏纳焦苦，勿食

汉东王先生《家宝》小儿受六气说云∶大凡小儿受其六气。六气者，筋、骨、血、肉、精、气也。
筋实则力多。骨实则早行立。血实则形瘦多发。肉实则少病，其母乳多汁则粗紫色。精实则灵利，多语笑，
不怕寒暑。气实则少发而体肥。
《圣济经》原化篇·凝形殊禀章说道：天地，是形体中最大的存在；阴阳，是气中最大的存在。只有形体与气相互依赖才能确立，从未有过偏废的情况。男女交合精气，万物由此化生，天地的阴阳形体与气便蕴含其中。谈及七八之数，七为少阳，八为少阴，二者相互感应而流通。所以女子十四岁天癸至，男子十六岁天癸至，便以阴阳交合而孕育生命之始。谈及九十之数，九为老阳，十为老阴，二者相互包容而赋予形体。所以阴数穷尽于十，男性能环绕它；阳数穷尽于九，女性能方正它，这是以阴阳相生而成终的缘故。元气孕育，都始于子时（或子位）。从子位推算，男性向左旋转，累积岁月三十年到达巳位；女性向右旋转，累积岁月二十年到达巳位。巳为正阳，阴实际上顺从它。从巳月开始怀孕，男性向左旋转十月，婴儿生于寅月；女性向右旋转十月，婴儿生于申月。申为三阴，寅为三阳，生育的时机便彰显出来了。其禀赋方面，身体有刚柔之分，脉象有强弱之别，气有多寡之差，血有盛衰之异，都是一定而不可改变的。至于不同地域，则所产子女有多寡的适宜差异。吉祥之事有祥兆，所做的梦也各自应验其类别。因此，荆州、扬州土地薄瘠多生女儿，雍州、翼州土地肥沃多生儿子。熊、罴是男子的祥兆，虺、蛇是女子的祥兆，这些都是道理可以推知的。胎化之法，有所谓“转女为男”的说法，也都是理之自然。如食用公鸡肉，是取自然界出产中完整的阳精。佩戴雄黄，是取大地出产中完整的阳精。持弓矢，坐卧斧斤，是取人事中显现的刚物之气。气类暗中相通，造化秘密转移，必定在三个月胎儿成形之前，因为此时仪态尚未具备，阳可以胜阴，变女为男，道理本就是这样。
杨大邺《童子秘诀》记载：小儿十月养胎，需避开禁忌以免克罚。第一个月妊娠，胎元本于肝脏，主养魂魄，所以这个月宜多吃酸味食物，以助益眼睛，自然一脏强盛。食物味道辛辣，因为肺纳辛味，主金克木，恐怕损伤肝脏。第二个月也是如此，为什么呢？因为少阳脉养胆，肝与胆相合的缘故。第三个月，肺脏主养心的脉，主神，这个月宜增加辛、酸之物，食用焦苦之物。因为肺主金，其脏纳辛，以助于金气。食用苦味食物，因为心纳苦味，主火，火克金的缘故。第四个月，心脏主养肾，这个月宜增加焦味，以助火。因为心主火，其脏纳焦苦，不要食酸，因为肾脏纳咸味，主水的缘故。第五个月，肾脏主养脾，这个月宜增加咸味，少吃甘甜之物。因为脾主土，土因克制水（注：此处原文逻辑似有误，通常土克水，但语境为养脾，故增咸以制水护土或顺应五行，依原文直译）的缘故。第六个月，脾脏主养气，这个月增加甜味以助土。因为土主脾的缘故。第七个月，筋骨养形而能动转，少吃咸味食物。只要五味相互滋助，甜淡得当，因为这个月胎儿已通，九窍上下相应。第八个月，形体与精神俱足成就，味道都宜减省，不要吃热毒及鸡、兔、狗、猪、牛、马、鸟、雀等肉，这些都是伤胎之物，也会生出赤瘤，务必戒除。只需听经，亲近善事，居住在静室，所生的儿女寿命长久且多尊贵。切忌发怒，频繁活动，然而用力行走坐卧不得太久。必须谨慎。第九个月，谨慎忌讳吃各种烤爆、腥臭、鳞甲蛊惑之物，以及壅毒肥滑粘腻之物，直到月初都要忌口，恐怕伤害孩子头脑，乃生下后多生恶疮壅毒。第十个月婴儿已出生，血脉上下循环，化为乳汁，遍信之道，只要根据月份调护，自然男女无克罚，筋骨圆满，聪明长寿，为人容易抚养，没有夭亡了。
汉东王先生《家宝》关于小儿受六气的说法称：大凡小儿承受其六气。六气，指筋、骨、血、肉、精、气。筋实则力气多。骨实则早能行走站立。血实则身形瘦弱头发多。肉实则少病，其母乳汁多则呈粗紫色。精实则灵利，多语笑，不怕寒暑。气实则少发病而身体肥胖。
The "Original Transformation Chapter" (Yuanhua Pian) of the *Shengji Jing* states in the "Chapter on Distinct Endowments of Formed Nature" (Ningxing Shubing Zhang): Heaven and Earth are the greatest of forms; Yin and Yang are the greatest of Qi. Only when form and Qi support each other can they be established, never being neglected or abandoned. When male and female essence combine, all things are transformed, and the forms and Qi of Heaven and Yin and Yang are contained within. Speaking of the numbers seven and eight: seven is Shaoyang (Lesser Yang), and eight is Shaoyin (Lesser Yin); they interact and circulate. Therefore, when girls reach fourteen years old, Tian Gui (menstrual fluid/reproductive essence) arrives; when boys reach sixteen years old, Tian Gui arrives. Thus, through the intersection of Yin and Yang, the beginning of life is signaled. Speaking of the numbers nine and ten: nine is Laoyang (Old Yang), and ten is Laoyin (Old Yin); they envelop each other to bestow form. Therefore, Yin reaches its limit at ten, which men can encircle; Yang reaches its limit at nine, which women can square. This is because of the generation and completion of Yin and Yang. The gestation of Yuan Qi (Primordial Qi) all begins at Zi (the first earthly branch, corresponding to midnight or the north). Counting from Zi, males rotate leftward, accumulating thirty years to reach Si; females rotate rightward, accumulating twenty years to reach Si. Si represents Zhengyang (True Yang), and Yin actually follows it. From the month of Si during pregnancy, males rotate leftward for ten months, and the child is born in the month of Yin; females rotate rightward for ten months, and the child is born in the month of Shen. Shen represents Sanyin (Three Yin), and Yin represents Sanyang (Three Yang), thus revealing the timing of birth and reproduction. Regarding endowments, the body has rigidity and flexibility, the pulse has strength and weakness, Qi has abundance and scarcity, and Blood has prosperity and decline; these are fixed and unchangeable. As for different regions, there are appropriate variations in the number of offspring. Auspicious events have omens, and dreams correspond to their respective categories. Therefore, in Jingzhou and Yangzhou, where the soil is thin, many daughters are born; in Yongzhou and Yizhou, where the soil is thick, many sons are born. Bears and black bears are omens for males, vipers and snakes are omens for females; these are principles that can be deduced. In the methods of fetal transformation, there is what is called "turning a female into a male," which is also natural according to principle. For example, eating rooster meat takes the complete Yang essence from heavenly productions. Wearing Realgar takes the complete Yang essence from earthly productions. Handling bows and arrows, resting near axes and hatchets, takes the rigid objects manifested in human affairs. Qi of similar types secretly communicates, and Creation secretly shifts. This must happen before the fetus takes shape at three months, because at that time, the structure is not yet formed, Yang can overcome Yin, turning a female into a male; this is indeed the principle.
Yang Daye's *Secrets of the Boy* states: During the ten months of fetal nourishment for infants, one must avoid taboos to prevent detrimental influences. In the first month of pregnancy, the fetus originates from the Liver, which governs the Hun (Ethereal Soul) and Po (Corporeal Soul). Therefore, in this month, it is advisable to eat more sour foods to assist the eyes, naturally strengthening the organ. Spicy flavors should be avoided because the Lung accepts pungency, governing Metal overcoming Wood, which might damage the Liver. The second month is the same. Why? Because the Shaoyang channel nourishes the Gallbladder, and the Liver and Gallbladder are interiorly-exteriorly related. In the third month, the Lung governs the nourishment of the Heart's vessels and governs the Shen (Spirit). In this month, it is advisable to add pungent and sour foods, and consume slightly burnt/bitter foods. Because the Lung governs Metal, and its organ accepts pungency to aid Metal Qi. Consuming bitter foods is because the Heart accepts bitterness, governing Fire, and Fire overcomes Metal. In the fourth month, the Heart governs the nourishment of the Kidney. In this month, it is advisable to increase burnt flavors to aid Fire. Because the Heart governs Fire, and its organ accepts burnt and bitter flavors; do not eat sour, because the Kidney accepts salty flavors and governs Water. In the fifth month, the Kidney governs the nourishment of the Spleen. In this month, it is advisable to increase salty flavors and eat less sweet foods. Because the Spleen governs Earth, and Earth controls Water. In the sixth month, the Spleen governs the nourishment of Qi. In this month, increase sweet foods to aid Earth. Because Earth governs the Spleen. In the seventh month, tendons and bones nourish the form and enable movement; eat less salty food. As long as the five flavors mutually nourish, and sweet and bland flavors are balanced, because in this month the fetus is connected, and the nine orifices above and below correspond. In the eighth month, form and spirit are fully developed. Flavors should all be reduced. Do not eat hot-toxic foods or meats of chickens, rabbits, dogs, pigs, cows, horses, birds, sparrows, etc., as these are damaging to the fetus and may cause red tumors; strictly avoid them. Simply listen to scriptures, approach goodness, dwell in quiet rooms, and the children born will live long and be noble. Strictly avoid anger, move frequently, but do not sit, lie down, walk, or stand with excessive effort for too long. Must be cautious. In the ninth month, carefully avoid roasted, fried, fishy, smelly, scaled, or蛊 (poisonous/enticing) foods, as well as clogging, toxic, fatty, slippery, and sticky foods. Avoid these until the beginning of the month, lest you damage the child's head, leading to many bad sores and toxins after birth. In the tenth month, the infant is born, blood and vessels circulate up and down, transforming into breast milk. Following the path of universal trust, if care is adjusted according to the months, naturally there will be no detrimental influences between male and female, tendons and bones will be complete, intelligence and longevity will be achieved, the person will be easy to raise, and there will be no premature death.
Mr. Wang from Handong, in his *Family Treasure*, regarding the theory of infants receiving the Six Qi, says: Generally, infants receive the Six Qi. The Six Qi refer to Tendons, Bones, Blood, Flesh, Essence, and Qi. If Tendons are solid, strength is abundant. If Bones are solid, walking and standing begin early. If Blood is solid, the body is thin and hair is abundant. If Flesh is solid, diseases are few; if the mother's milk is abundant, it appears coarse and purplish. If Essence is solid, the child is agile and intelligent, talks and laughs often, and fears neither cold nor heat. If Qi is solid, illnesses are rare, and the body is fat.
