《千金方》云∶夫婚姻生育者，人伦之本，王化之基。圣人设教备论，厥旨后生，莫能
精晓，临事之日，昏尔若愚，今具述求子之法，以贻后嗣，同志之士，或可览焉。
又云∶夫欲求子者，先知夫妻本命、五行相生及与德合并本命不在子伏 死墓中生者，
则求子必得。若其本命五行相克及与形杀冲破并在子休 死墓中生者，则求子不可得。慎无
措意，纵后得者，于后方欲示人。若其相生，并遇福德者，仍者须依法如方，避乎禁忌，则
所诞儿子，尽善尽美，难以具陈矣。
又云∶夫欲令儿子吉良者，交会之日当避景丁日及弦、望、朔、晦、大风、大雨、大雾、
大寒、大暑、雷、电、霹雳、天地昏冥、日月无光、虹霓、地动、日月薄蚀，此时受胎，非
只百倍损于父母，生子或喑、 、聋、KT 顽愚、癫狂、挛跋、盲眇、多病，短寿、不孝、
不仁，又避火光星辰之下，神庙佛寺之中，井灶、清厕之侧，坟墓尸KT 之旁，皆悉不可。
又云∶夫交会如法，则消福德，大圣善人降托胎中，仍令父母性行调顺，所作合应，家
道日隆，祥瑞竟集；若不如法，则有薄福，愚痴恶人来托胎中，令父母性行凶险，所作不成，
家道日否，咎征屡至，虽生成长，国灭身亡。夫祸福之征，有如影响，此乃必然之理，何不
思之。
又云∶以夜半后生气时泻精，有子皆男，必寿而贤明高爵也。（今按∶《大清经》云∶从
夜半日中为生气，从日中至夜半为死气。）
又云∶王相日、贵宿日尤吉。（其曰有本书。）
《产经》云∶黄帝曰∶人之始生，本在于胎合阴阳也。夫合阴阳之时，必避九殃。九殃
者，日中之子，生则呕逆，一也；夜半之子，天地闭塞，不喑则聋盲，二也；日蚀之子，体
戚毁伤，三也；雷电之子，天怒头威，必易服狂，四也；月蚀之子，与母俱凶，五也；虹霓
之子，若作不祥，六也；冬夏日至之子，生害父母，七也；弦望之子，必为乱兵风盲，八也；
醉饱之子，必为病癫、疽、痔、有疮，九也。
又云∶有五观子生不祥∶月水未清，一观也；父母有疮，二观也；丧服未除有子，三观
也；温病未愈有子，身亲丧，四观也；妊身而忧恐重复惊惶，五观也。
《玉房秘诀》云∶合阴阳有七忌∶
第一之忌，晦朔弦望，以合阴阳，损气，以是生子，子必刑残，宜深慎之。
第二之忌，雷风天地感动，以合阴阳，血脉涌，以是生子，子必痈肿。
第三之忌，新饮酒饱食，谷气未行，以合阴阳，腹中膨亨，小便白浊，以是生子，子必
癫狂。
第四之忌，新小便，精气竭以合阴阳，经脉得涩，以是生子，必妖孽。
第五之忌，劳倦重担，志气未安，以合阴阳，筋腰苦痛，以是生子，必夭残。
第六忌，新沐浴，发肤未燥，以合阴阳，令人短气，以是生子，子必不全。
第七忌，兵坚盛怒，茎脉痛，当令不合，内伤有病。如此为七伤。
又云∶人生喑聋者，是腊目暮之子。腊暮百鬼聚会，终夜不息，君子斋戒，小人私合阴
阳，其子必喑聋。
人生伤死者，名曰火子。燃烛未灭而合阴阳，有子必伤，死市人。
人生癫狂，是雷电之子，四月五月大雨霹雳，君子斋戒，小人私合阴阳，有子必癫狂。
人生为虎野狼所食者，重服之子，孝子戴麻，不食肉，君子羸顿，小人私合阴阳，有子必
为虎野狼所合。
人生溺死者，父母过藏胞于铜器中，覆以铜器，埋于阴垣下，入地七尺，名曰童子裹，
溺死水中。
又云∶大风之子多病，雷电之子狂癫，大醉之子必痴狂，劳倦之子必夭伤，月经之子兵
亡，黄昏之子多变，人定之子不暗则聋，日入之子口舌不祥，日中之子癫病，晡时之子自毁
伤。
又云∶素女曰∶求子法自有常体，清心远虑，安定其襟袍，垂虚斋戒，以妇人月经后三
日，夜半之后，鸡鸣之前，嬉戏令女盛（咸，或本）动，乃往从之，适其道理，同其快乐，
却身施泻，下精，欲得去玉门入半寸，不尔过子宫，千翼。勿过远至麦齿，远则过子门，不
入子户。若依道术，有有子贤良而老寿也。
又云∶彭祖曰∶求子之法，当蓄养精气，勿数施舍，以妇人月事断绝，洁净三五日而交
有子，则男听明才智，老寿高贵，生女清贤，配贵人。
又云∶常向晨之际，以御阴阳，利身便躯，精光益张，生子富长命。
又云∶素女曰∶夫人合阴阳，当避禁忌，常乘生气，无不老寿。若夫妇俱老，虽生化有
子，皆不寿也。
又云∶男女满百岁，生子亦不寿，八十男可御十五、十八女，则生子不犯禁忌，皆寿老。
女子五十得少夫，亦有子。
又云∶妇人怀子未满三月以成子，取男子冠缨烧之，以取灰，以酒尽服之，生子富贵明
达，秘之秘之。
又云∶妇人无子，令妇人左手持小豆二七枚，右手扶男子阴头纳女阴中，左手纳豆着口
中，女自男阴同入，闻男阴精下，女仍当咽豆，有效，万全不失一也。
洞玄子云∶几欲求子，候女之月经断后，则交接之。一日三日为男，四日五日为女，五
日以后，徒损精力，终无益也。交接泄精之时，候女快来，须与一时同泄，泄必须尽。先令
女正面仰卧，端心一意，闭目内想，受精气。故老子曰∶夜半得子为上寿，夜半前得子为中
寿，夜半后得子下寿。
又云∶凡女子怀孕之后，须行善事，勿视恶色，勿听恶语，省淫欲，勿咒咀，勿骂詈，
勿惊恐，勿劳倦，勿妄语，勿忧愁，勿食生冷醋滑热食，勿乘车马，勿登，勿临深，勿下 ，
勿急行，勿服饵，勿针灸。皆须端心正念，常听经书，遂令男女如是，聪明智慧，忠真贞良，
所谓胎教者也。
《千金方》说：婚姻与生育，是人伦的根本，也是王道教化的基础。圣人设立教化并详尽论述，其主旨在于教导后辈，但很少有人能精通知晓，到了办事的时候，却昏昧愚钝。现在详细陈述求子的方法，以留给后代，志同道合的人，或许可以阅览。
又说：想要求子的人，先要知晓夫妻双方的本命、五行相生以及德行合并后的本命不在“子”位的伏、死、墓、生等状态中，那么求子必定成功。如果本命五行相克，以及遇到形杀、冲破，并且在本命处于“子”位的休、死、墓、生等状态中，那么求子不可得。千万不要在意，即使后来得到了，在后面的方书中也要向人展示。如果五行相生，并且遇到福德吉星，仍然必须依照法规如方术行事，避开禁忌，那么所生的儿子，尽善尽美，难以详尽陈述了。
又说：想要让儿子吉祥善良，交合的日子应当避开景丁日（农历五月午日）以及弦日（初七、廿三）、望日（十五）、朔日（初一）、晦日（月末）、大风、大雨、大雾、大寒、大暑、雷、电、霹雳、天地昏暗、日月无光、虹霓、地震、日月食，此时受孕，不仅百倍损害父母，生下的孩子可能哑、瞎、聋、痴呆愚笨、癫狂、痉挛跛足、盲眼、多病、短寿、不孝、不仁，还要避开火光星辰之下，神庙佛寺之中，井灶、清洁厕所之侧，坟墓尸体旁边，都不可以。
又说：交合如果合乎法度，就会消减福德（注：此处原文逻辑似有矛盾或特定语境，通常指积德或顺应天道，结合下文“大圣善人降托胎中”，意指顺应天道则得福），大圣善人会降临托胎于腹中，从而使父母性情行为调和顺遂，所作所为符合应验，家道日益兴隆，祥瑞聚集；如果不合法度，就会有薄福，愚痴恶人来托胎中，使父母性情行为凶险，所作所为不成，家道日益衰败，灾祸征兆屡次到来，即使生长成人，也会国灭身亡。祸福的征兆，就像影子跟随形体一样，这是必然的道理，为什么不思考呢？
又说：在夜半之后生气旺盛时泄精，有儿子都是男性，一定长寿而且贤明高爵。（现在按语：《大清经》说：从夜半到日中为生气，从日中到夜半为死气。）
《产经》说：黄帝说：人的初始生命，根本在于胞胎中阴阳结合。在结合阴阳的时候，必须避开九种灾殃。九种灾殃是：日中之子，生下来就呕吐逆气，这是一；夜半之子，天地闭塞，不是哑就是聋盲，这是二；日蚀之子，身体戚伤毁损，这是三；雷电之子，天怒头威，一定改变服饰发狂，这是四；月蚀之子，与母亲一起凶险，这是五；虹霓之子，如果作出不祥之事，这是六；冬夏日至之子，生下来危害父母，这是七；弦望之子，一定成为乱兵风盲（注：指战乱中风邪致盲或类似灾祸），这是八；醉饱之子，一定成为病癫、疽、痔、有疮，这是九。
又说：有五观（观察/征兆）显示生子不祥：月经未清，是一观；父母有疮，是二观；丧服未除而有子，是三观；温病未愈而有子，身亲丧（注：此处原文可能有误，通常指母体受惊或病重），是四观；怀孕而忧恐重复惊惶，是五观。
《玉房秘诀》说：合阴阳有七种忌讳：
第一忌讳，晦朔弦望（农历每月初一、十五及上下弦日），进行合阴阳，损伤元气，因此生子，儿子一定刑残，应该深深谨慎。
第二忌讳，雷风天地感动，进行合阴阳，血脉涌起，因此生子，儿子一定痈肿。
第三忌讳，新近饮酒饱食，谷气未行，进行合阴阳，腹中膨亨（胀满），小便白浊，因此生子，儿子一定癫狂。
第四忌讳，新近小便，精气竭乏，进行合阴阳，经脉得到涩滞，因此生子，一定是妖孽。
第五忌讳，劳倦重担，志气未安，进行合阴阳，筋腰苦痛，因此生子，一定夭折残疾。
第六忌讳，新近沐浴，发肤未干，进行合阴阳，令人短气，因此生子，儿子一定不全。
第七忌讳，兵器坚硬盛怒，茎脉痛，应当令其不合，内伤有病。这叫做七伤。
又说：人生来哑聋的，是腊月暮色时的子。腊月暮时百鬼聚会，整夜不息，君子斋戒，小人私下合阴阳，其子一定哑聋。
人生来伤死的，名叫火子。燃烛未灭而合阴阳，有子一定受伤，死于市井之人。
人生来癫狂的，是雷电之子，四月五月大雨霹雳，君子斋戒，小人私下合阴阳，有子一定癫狂。
人生来被虎野狼所食的，是重服之子（穿重孝者），孝子戴麻，不吃肉，君子羸顿（虚弱疲惫），小人私下合阴阳，有子一定被虎野狼所合（注：此处原文逻辑混乱，疑为传抄错误，意指此类时辰受孕生子易遭野兽伤害）。
人生来溺死的，父母过藏胞于铜器中，覆以铜器，埋于阴垣下，入地七尺，名叫童子裹，溺死水中。
又说：大风之子多病，雷电之子狂癫，大醉之子一定痴狂，劳倦之子一定夭伤，月经之子兵亡，黄昏之子多变，人定之子不暗则聋，日入之子口舌不祥，日中之子癫病，晡时之子自毁伤。
又说：素女说：求子法自有常规体式，清心远虑，安定其襟袍，垂虚斋戒，在妇人月经后三日，夜半之后，鸡鸣之前，嬉戏令女子兴奋（咸，或本）动，然后前往从之，适其道理，同其快乐，退身施泻，下精，想要进入玉门半寸，不然超过子宫，千翼（注：此处文字疑似错简或衍文，意为不可过度深入或偏离正道）。不要过远至麦齿（注：疑为穴位或身体部位代称，意指过深），远则过子门，不入子户。如果依道术，有有子贤良而老寿也。
又说：彭祖说：求子的方法，应当蓄养精气，不要多次施舍，在妇人月经断绝，洁净三五日后交合有子，则男听明才智，老寿高贵，生女清贤，配贵人。
又说：常在晨间之际，以御阴阳，利身便躯，精光益张，生子富长命。
又说：素女说：夫人合阴阳，应当避开禁忌，常乘生气，无不老寿。如果夫妇俱老，虽然生化有子，皆不寿也。
又说：男女满百岁，生子亦不寿，八十男可御十五、十八女，则生子不犯禁忌，皆寿老。女子五十得少夫，亦有子。
又说：妇人怀子未满三月以成子，取男子冠缨烧之，以取灰，以酒尽服之，生子富贵明达，秘之秘之。
又说：妇人无子，令妇人左手持小豆二七枚（14枚），右手扶男子阴头纳女阴中，左手纳豆着口中，女自男阴同入，闻男阴精下，女仍当咽豆，有效，万全不失一也。
洞玄子说：几欲求子，候女之月经断后，则交接之。一日三日为男，四日五日为女，五日以后，徒损精力，终无益也。交接泄精之时，候女快来，须与一时同泄，泄必须尽。先令女正面仰卧，端心一意，闭目内想，受精气。故老子曰：夜半得子为上寿，夜半前得子为中寿，夜半后得子下寿。
又说：凡女子怀孕之后，须行善事，勿视恶色，勿听恶语，省淫欲，勿咒咀，勿骂詈，勿惊恐，勿劳倦，勿妄语，勿忧愁，勿食生冷醋滑热食，勿乘车马，勿登，勿临深，勿下 ，勿急行，勿服饵，勿针灸。皆须端心正念，常听经书，遂令男女如是，聪明智慧，忠真贞良，所谓胎教者也。
The *Qianjin Fang* states: Marriage and procreation are the foundation of human ethics and the basis of royal education. The sages established teachings and discussed them in detail, with the main purpose of instructing later generations. However, few people can understand them thoroughly; when the time comes to act, they become confused and foolish. Now, I will fully describe the methods for seeking offspring, to be left for descendants. Those with similar aspirations may wish to read this.
It also states: Those who wish to conceive should first know the natal characters (Benming) of both husband and wife, the mutual generation of the Five Elements, and whether their combined virtue and natal character avoid unfavorable states such as "Fu" (Hidden), "Si" (Death), "Mu" (Tomb), or "Sheng" (Birth) in relation to the Earthly Branch "Zi". If these conditions are met, conception will surely succeed. If the natal characters involve mutual restriction of the Five Elements, or encounter "Xingsha" (Form Killing) and "Chongpo" (Clash and Break), and are in unfavorable states like "Xiu" (Rest), "Si" (Death), or "Mu" (Tomb) relative to "Zi", then conception will not succeed. Do not dwell on this unnecessarily. Even if one conceives later, it should be recorded in subsequent texts for reference. If the Five Elements generate each other and favorable fortune stars are present, one must still follow the prescribed methods and avoid taboos. The child born will be perfect in every way, which is difficult to fully describe.
It further states: To ensure the child is auspicious and virtuous, intercourse should be avoided on Jingding days (the Wu day of the fifth lunar month), as well as on Xian days (7th and 23rd lunar days), Wang days (15th lunar day), Shuo days (1st lunar day), Hui days (last lunar day), during strong winds, heavy rain, dense fog, extreme cold, extreme heat, thunder, lightning, claps of thunder, dark skies, eclipses, rainbows, earthquakes, and solar/lunar eclipses. Conception during these times will harm the parents a hundredfold, and the child may be mute, blind, deaf, retarded, insane, convulsed, lame, visually impaired, prone to illness, short-lived, unfilial, and unkind. One should also avoid intercourse under firelight or starlight, in temples or Buddhist shrines, near wells, stoves, clean toilets, or beside graves and corpses.
It states: If intercourse follows proper rituals, it aligns with cosmic virtue, allowing great sages and virtuous beings to incarnate. This harmonizes the parents' temperament and actions, leading to family prosperity and the gathering of auspicious signs. If improper, thin fortune prevails, and foolish or evil spirits incarnate, causing parents to become vicious and their endeavors to fail. The family declines, disasters multiply, and even if the child survives to adulthood, it may lead to ruin. The signs of fortune and misfortune are as inevitable as shadow following form; why not reflect on this?
It states: Ejaculating during the "Shengqi" (Vital Qi) period after midnight results in male offspring who will be long-lived, wise, and hold high rank. (Note: The *Daqing Jing* states that from midnight to noon is Shengqi, and from noon to midnight is Siqi (Dead Qi).)
It states: Days associated with Wang (Prosperous) and Xiang (Minister) phases, and noble constellations, are especially auspicious. (Details are found in specific books.)
The *Chan Jing* records Huangdi saying: Human life begins in the womb through the union of Yin and Yang. During this union, nine calamities must be avoided:
1. A child conceived at noon will suffer from vomiting and regurgitation.
2. A child conceived at midnight, when heaven and earth are closed, will be mute or blind/deaf.
3. A child conceived during a solar eclipse will have bodily injuries or deformities.
4. A child conceived during thunder/lightning will exhibit signs of heavenly wrath, likely becoming insane.
5. A child conceived during a lunar eclipse will bring misfortune to both mother and child.
6. A child conceived during a rainbow phenomenon may engage in inauspicious acts.
7. A child conceived during the winter or summer solstice will harm the parents.
8. A child conceived during Xian or Wang days will suffer from war-related trauma or blindness caused by wind pathogens.
9. A child conceived while the parents are drunk or overly full will suffer from epilepsy, carbuncles, hemorrhoids, or sores.
It states there are five observations indicating inauspicious conception:
1. Conception before menstrual blood has completely cleared.
2. Conception when parents have skin sores.
3. Conception while mourning attire is still worn.
4. Conception while suffering from warm diseases or bereavement.
5. Conception accompanied by repeated worry, fear, and panic during pregnancy.
The *Yufang Mijue* lists seven taboos for sexual intercourse:
1. Intercourse on Shuo, Wang, Xian, or Shangxian days damages Qi, resulting in physically disabled offspring. Caution is required.
2. Intercourse during thunderstorms or windy weather causes blood vessels to surge, leading to offspring prone to abscesses and swelling.
3. Intercourse immediately after drinking or overeating, when grain Qi has not circulated, causes abdominal bloating and cloudy urine, resulting in insane offspring.
4. Intercourse immediately after urination, when Jing-Essence is depleted, causes meridian stagnation, leading to abnormal or monstrous offspring.
5. Intercourse while fatigued from labor or carrying heavy loads, when spirit and Qi are unsettled, causes pain in tendons and waist, resulting in premature death or disability.
6. Intercourse immediately after bathing, while hair and skin are damp, causes shortness of breath, leading to incomplete or malformed offspring.
7. Intercourse while angry or experiencing penile pain constitutes internal injury and disease. These are called the Seven Injuries.
It states: Children born mute or deaf are those conceived at dusk in the twelfth lunar month, when ghosts gather all night. While virtuous men fast and abstain, commoners engage in secret intercourse, resulting in mute or deaf children.
Children who die young or suffer injury are called "Fire Children," conceived while candles are burning but not yet extinguished. Such children are destined for injury or death in marketplaces.
Children born insane are "Thunder/Lightning Children," conceived during heavy rains and thunder in April or May. While virtuous men fast, commoners engage in secret intercourse, resulting in insane children.
Children eaten by tigers or wolves are "Heavy Mourning Children," conceived while wearing heavy mourning clothes and abstaining from meat. While virtuous men weaken themselves through fasting/mourning, commoners engage in secret intercourse, resulting in children vulnerable to wild beasts.
Children who drown are related to the practice of burying fetal membranes in copper vessels deep underground, known as "Boy's Wrap."
It states: Children conceived in strong winds are prone to illness; those in thunder/lightning are insane; those from drunkenness are retarded; those from fatigue die young; those from menstruation die in war; those from twilight are unstable; those from Ren Ding hour (9-11 PM) are blind or deaf; those from sunset have speech issues; those from noon have epilepsy; those from Wu hour (3-5 PM) self-harm.
Su Nu says: The method for seeking offspring has standard principles. Clear the mind, remove distractions, maintain purity and fasting. Three days after the woman's menstruation ends, between midnight and cockcrow, engage in play to stimulate the woman, then proceed according to natural principles, sharing joy. Withdraw slightly to ejaculate, ensuring semen enters about half an cun into the Yu Men (jade gate/vagina). Do not go too deep towards the Zi Gong (uterus) or Zi Men (cervix). Following these Daoist arts ensures wise, long-lived offspring.
Peng Zu says: Preserve Jing-Essence and avoid frequent ejaculation. Conceive three to five days after menstruation ceases and the body is clean. Male offspring will be intelligent, long-lived, and noble; female offspring will be virtuous and marry nobility.
Intercourse in the early morning benefits the body, enhances Jing-Light, and produces wealthy, long-lived offspring.
Su Nu says: Avoid taboos and seek Shengqi (Vital Qi) for longevity. If both partners are old, offspring may not live long. Even if a couple reaches 100 years, offspring may not be long-lived. An 80-year-old man with a 15-18 year old woman avoids taboos, producing long-lived offspring. A 50-year-old woman with a younger husband may also conceive.
If a woman is less than three months pregnant, burn the cord from a man's cap, mix the ash with wine, and drink it. This ensures the child will be wealthy and wise. Keep this secret.
For women unable to conceive: The woman holds 14 adzuki beans in her left hand and supports the man's penis with her right hand, inserting it into her vagina. She places the beans in her mouth. As she receives semen, she swallows the beans. This method is effective and reliable.
Dongxuanzi says: After menstruation ends, intercourse determines gender: 1st or 3rd day yields a boy; 4th or 5th day yields a girl. After the 5th day, energy is wasted with no benefit. At ejaculation, synchronize with the woman's climax, ensuring complete emission. The woman should lie supine, focus her mind, close her eyes, and visualize receiving Qi. Laozi said: Conceiving at midnight yields maximum longevity; before midnight, medium longevity; after midnight, minimum longevity.
It states: Once pregnant, the woman must perform good deeds, avoid ugly sights and bad words, reduce lust, avoid cursing or scolding, avoid fright, fatigue, lies, and sorrow. Avoid raw, cold, sour, slippery, or hot foods. Avoid riding horses/carriages, climbing heights, approaching depths, sudden movements, taking herbs, or acupuncture. Maintain upright thoughts, listen to scriptures, and ensure the child becomes wise, loyal, and virtuous. This is prenatal education (Taijiao).
