凡欲要儿子生吉良者。交会之日。常避丙丁及弦望朔晦。大风、大雨、大雾、大寒、大
暑、雷电霹雳。天地昏暝。日月无光。虹霓地动。日月薄蚀。此时受胎。非止百倍损于父母。
生子或喑哑聋 。顽愚癫狂。挛跛盲眇。多病短寿。不孝不仁。又避日月火光。星辰之下。
神庙佛寺之中。井灶圊厕之侧。 墓尸柩之傍。皆悉不可。夫交会如法。则有福德大智善
人降托胎中。仍令父母性行调顺。所作和合。家道日隆。祥瑞竞集。若不如法。则有薄福愚
痴恶人来托胎中。则令父母性行凶险。所作不成。家道日否。殃咎屡至。虽生成长。家国灭
亡。夫祸福之验有如影响。此乃必然之理。可不再思之。

凡希望儿子出生吉祥安康的，在行房交合之日，应当避开丙日、丁日（天干属火的日子），以及农历每月的弦日（初七、初八或廿二、廿三）、望日（十五）、朔日（初一）和晦日（月末）。还要避开大风、大雨、大雾、严寒、酷暑、雷电霹雳等恶劣天气。天地昏暗不明，日月无光，出现虹霓、地震，或者发生日月食的时候，此时受孕，不仅对父母损害百倍，生下的孩子可能哑巴、聋子、瞎子，或者愚笨痴呆、癫狂，肢体挛缩跛足、失明，多病且短命，不孝不仁。还要避开月光火光之下，神庙佛寺之中，井台灶台厕所旁边，坟墓尸体棺木之侧，这些地方都不可行房。如果行房合乎法度，就会有积有福德、大智善人降托入胎中，从而使父母性情行为调和顺遂，所作所为和谐成功，家道日益兴隆，祥瑞之事竞相聚集。如果不合法度，就会有薄福愚痴恶人来托胎中，就会使父母性情行为凶险，所作所为不能成功，家道日益衰败，灾祸殃咎屡次到来。即使孩子生长成人，也会导致家国灭亡。祸福的验证就像回声和影子一样迅速，这是必然的道理，能不深思吗？

胎前避忌（出自《产后救急方》）
刚受孕后，凡是妨碍胎儿的药物，都不宜服用。如果房事不加节制，会导致胎孕不成。
妊娠六七个月后，醉酒饱食过度，房事不节制的，产妇多有腰疼腹痛的疾病，严重时伤胎。不宜登高举重，否则可能导致跌扑挫闪损伤胎儿。
古人怀孕每月就分床异寝，此时戒除色欲，否则生子时头部带着秽恶之气而出，俗称为“戴白生”，这个孩子必定患有胎毒。
妊娠饮食禁忌方法（出自《便产须知》）
吃鸡蛋、鲜干鲤鱼，会使孩子多生疮疡。吃豆酱合藿香，会导致堕胎。吃兔肉，会使孩子唇裂。吃狗肉，会使孩子失声。喝酒，多吃雀肉，会使孩子不知羞耻。吃桑葚及鸭子，会使孩子倒悬难产。吃驴马肉会使孕期延长。吃鱼鳖卵，会伤害婴儿。吃山羊肉，会使孩子多病。吃骡肉，会导致难产。吃鸡肉及糯米，会使孩子腹中多虫。喝生水，会使孩子胎热。多吃水冷、淘洗过的葵菜、生冷菜果，会使孩子患胎寒。大小便去不寻常的地方，会导致半产杀儿。这些都是大的禁忌。
饮食禁忌与起居注意
羊肝多吃，生子多厄难。蛙子导致孩子哑巴。螃蟹导致横生。生姜多吃，孩子生疮多指。干姜、蒜、鸡，有毒伤胎无益。粘腻难消化的食物伤胎。无鳞鱼不可吃。吃泥鳅过多，导致难产。菰子即菌类，有大毒。吃菌类多，导致婴儿风症夭折。不要乱服汤药。酒不要过量饮用。卧位生产尤其忌讳。不要乱妄针灸。不要在非正常地方大小便，否则会半产杀人。不要举重登高涉险。不要受大惊吓，否则孩子必患癫痫。宜自我宽解。不要多睡，须时常行走。体虚肾气不足，孩子必患解颅（囟门不合）。宜温补。脾胃不和营卫虚怯，孩子必羸瘦。自家及邻家兴造动土触犯其胎气，令儿破形损命。刀犯者，形体必伤。泥犯者，窍穴必塞。打击者，肤色必青黯。击搏者，肢体必拘挛。以上这些验证如反掌般容易，切宜避免。

For those who wish for a son to be born auspiciously and healthily, on the day of intercourse, one should avoid Bing (丙) and Ding (丁) days (days in the Heavenly Stems associated with Fire), as well as the Shang (弦, first or last quarter moon), Wang (望, full moon), Shuo (朔, new moon), and Hui (晦, last day of the lunar month). One must also avoid severe weather conditions such as strong winds, heavy rain, dense fog, extreme cold, extreme heat, thunder, lightning, and earthquakes. When heaven and earth are dim, sunlight and moonlight are obscured, rainbows appear, or solar/lunar eclipses occur, conception at these times will not only harm the parents a hundredfold but may also result in children who are mute, deaf, blind, foolish, insane, crippled, short-lived, unfilial, and unkind. One should also avoid intercourse under moonlight or firelight, inside temples or Buddhist shrines, near wells, stoves, or toilets, and beside graves, corpses, or coffins; all these places are forbidden. If intercourse follows proper methods, virtuous, blessed, wise, and good spirits will descend into the womb, causing the parents' nature and behavior to become harmonious and compliant, their endeavors to succeed, the family fortune to prosper daily, and auspicious signs to gather. If improper methods are used, wicked, ignorant, and ill-fated spirits will enter the womb, causing the parents' nature to become fierce and dangerous, their endeavors to fail, the family fortune to decline daily, and disasters to occur repeatedly. Even if the child grows up, it may lead to the destruction of the family or state. The verification of fortune and misfortune is as immediate as an echo or shadow; this is an inevitable principle, how can one fail to reflect upon it?
Methods for Timing Conception for Men and Women (from *Xianchan Xu Zhi*)
Regarding conception by men and women, if intercourse occurs on the first, third, or fifth day after the woman's menstruation ends, and coincides with a day when the moon resides in a noble constellation, and ejaculation takes place at midnight during the time when vital energy arises, a son will be born. Such sons will likely be long-lived, virtuous, intelligent, and hold high rank. If ejaculation occurs on the second, fourth, or sixth day after menstruation ends, the pregnancy will result in a daughter. Conception beyond the sixth day will not result in a viable fetus. Encountering "Wang" (King) or "Xiang" (Minister) days is particularly auspicious.
Method for Calculating Wang and Xiang Days (from *Xianchan Xu Zhi*)
Spring corresponds to Jia (甲) and Yi (乙); Summer corresponds to Bing (丙) and Ding (丁); Autumn corresponds to Geng (庚) and Xin (辛); Winter corresponds to Ren (壬) and Gui (癸).
Method for Calculating Noble Constellation Days
First Lunar Month: 1st, 6th, 9th, 10th, 11th, 12th, 14th, 21st, 24th, 29th.
Second Lunar Month: 4th, 7th, 8th, 9th, 10th, 12th, 14th, 19th, 22nd, 27th.
Third Lunar Month: 1st, 6th, 7th, 8th, 10th, 17th, 20th, 25th.
Fourth Lunar Month: 3rd, 4th, 5th, 6th, 8th, 10th, 15th, 18th, 22nd, 28th.
Fifth Lunar Month: 1st, 2nd, 3rd, 4th, 5th, 6th, 12th, 13th, 15th, 16th, 20th, 25th, 28th, 29th, 30th.
Sixth Lunar Month: 1st, 3rd, 10th, 13th, 18th, 23rd, 26th, 27th, 28th, 29th.
Seventh Lunar Month: 1st, 11th, 16th, 21st, 24th, 25th, 26th, 27th.
Eighth Lunar Month: 5th, 8th, 13th, 18th, 21st, 22nd, 23rd, 24th, 25th.
Ninth Lunar Month: 3rd, 6th, 11th, 16th, 19th, 20th, 21st, 22nd, 24th.
Tenth Lunar Month: 1st, 4th, 9th, 14th, 17th, 18th, 19th, 20th, 22nd, 29th.
Eleventh Lunar Month: 1st, 6th, 11th, 14th, 15th, 16th, 17th, 19th, 26th, 29th.
Twelfth Lunar Month: 4th, 9th, 12th, 13th, 14th, 15th, 17th, 24th, 27th.
If Spring matches with Jia Yin (甲寅) or Yi Mao (乙卯) days, Summer with Bing Wu (丙午) or Ding Si (丁巳) days, Autumn with Geng Shen (庚申) or Xin You (辛酉) days, and Winter with Ren Zi (壬子) or Gui Hai (癸亥) days, and these coincide with the aforementioned noble constellation days, it is especially excellent.
Taboos Before Pregnancy (from *Chanhou Jiufang*)
After initial conception, any drugs that hinder the fetus should not be taken. Failure to abstain from sexual activity can prevent successful conception.
In the seventh or eighth month of pregnancy, excessive drinking and overeating, along with unregulated sexual activity, often cause the mother to suffer from lower back pain and abdominal pain, potentially damaging the fetus. One should not climb heights or lift heavy objects, as falling or jarring injuries may damage the fetus.
Ancients slept in separate beds each month of pregnancy. Abstinence from lust during this time ensures the child is born without impurity. Violating this results in the child being born with "impurity on the head," commonly called "Dai Bai Sheng" (born wearing white/impurity), and the child will inevitably suffer from fetal toxins.
Dietary Taboos During Pregnancy (from *Xianchan Xu Zhi*)
Consuming eggs, fresh or dried carp, may cause the child to have many sores. Consuming bean paste with huoxiang (Agastache rugosa) may cause miscarriage. Consuming rabbit meat may cause cleft lip in the child. Consuming dog meat may cause loss of voice in the child. Drinking alcohol or eating too much sparrow meat may cause the child to lack shame. Consuming mulberries or duck meat may cause breech presentation. Consuming donkey or horse meat may prolong the gestation period. Consuming fish roe may harm the infant. Consuming goat meat may make the child prone to illness. Consuming mule meat may cause difficult labor. Consuming chicken meat and glutinous rice may cause intestinal parasites in the child. Drinking raw water may cause fetal heat. Consuming too much cold water, rinsed malva vegetables, or raw fruits and vegetables may cause fetal cold. Defecating or urinating in unusual places may lead to premature birth and death of the child. These are major taboos.
Dietary Taboos and Daily Living Precautions
Excessive consumption of sheep liver may bring hardships to the child. Frog meat may cause muteness in the child. Crabs may cause transverse lie. Excessive ginger may cause skin sores and polydactyly in the child. Dried ginger, garlic, and chicken are toxic to the fetus and of no benefit. Sticky and hard-to-digest foods damage the fetus. Scaleless fish should not be eaten. Excessive consumption of loaches may lead to dystocia. Guzi (mushrooms/fungi) has high toxicity; excessive consumption may cause neonatal convulsions and early death. Do not take decoctions arbitrarily. Do not drink alcohol excessively. Lying down during delivery is particularly taboo. Do not perform acupuncture or moxibustion arbitrarily. Do not defecate or urinate in inappropriate places, as this may cause premature birth and kill the child. Do not lift heavy objects, climb heights, or venture into danger. Avoid sudden fright, which may cause epilepsy in the child. Practice self-composure. Do not sleep too much; walk regularly. If the body is deficient and Kidney Qi is insufficient, the child may suffer from craniotabes (open fontanelles). Warmtonic therapies are suitable. If Spleen and Stomach harmony is disrupted and Ying and Wei (Nutritive and Defensive Qi) are weak, the child will be emaciated. Construction activities at home or by neighbors may disturb the fetal Qi, damaging the child's form and life. Injury by knives damages the form; injury by mud blocks orifices; blows cause dark discoloration; impacts cause contractures. These verifications are as clear as turning a hand; one must strictly avoid them.
Medication Taboos Before Pregnancy (from *Taichan Jiufang*)
Realgar (Xionghuang), Orpiment (Cihuang), Sulfur (Huang), Hematite (Daizhe), Arsenic (Pi), Croton Seed Frost (Badou Shuang), Mercury (Shuiyin), Lead Powder (Qianfen), Raw Gold Dust (Sheng Jin Xie), Niter (Xiao), Glauber's Salt (Yapo), Mirabilite (Mang), Aconitum heterophyllum (Huzhang), Podophyllum (Guijiu), Eucommia bark with arrows (Guijianyu), Pharbitis Seed (Qianniu), Achyranthes Root (Niuxi), Sichuan White Ginger (Chuan Baijiang), Tianxiong, Prepared Aconite Root (Fuzi), Sichuan Aconite (Chuan Caowu), Arisaema (Nanxing), Pinellia Tuber (Banxia), Veratrum (Lilu), Safflower (Honghua), Genkwa Flower (Yanhua), Euphorbia (Daji), Rhododendron (Zhizhu), Gelsemium (Yege), Ru (possibly referring to a specific herb), Bupleurum root (Baiwei), Aristolochia debilis (Duhen), Peony (Mudan), Sophora Fruit (Huai Zi), Gleditsia Sinensis (Zaojiao), Deutzia (Soushu), Peach Kernel (Taoren), Sparganium (Sanleng), Dry Bamboo Lacquer (Gan Tongqi), Thlaspi (Tongcao), Lygodium Spore (Qumai), Imperata Rhizome (Maogen), Dalbergia Odorifera (Sufangmu), Calculus Bovis (Niuhuang), Skin of Rat (Pishengshutu - likely a textual error or obscure term), Mylabris (Qingbanmao), Meloe (Didan), Leech (Mengchong), Hirudo (Shuizhi), Mole Cricket (Lougu), Silkworm Moth Pupa (Jiangcan), Crab Claws (Xiezhuajia), Centipede (Wugong), Gecko Skin (Xiyyi), White Fish (Baiyu), Donkey/Horse/Rabbit Meat, Chicken/Duck Meat, Alliums (Da Xiao Hu) in vegetables, Musk (Shexiang), Cinnamon Bark (Rougui), Snake Skin (She), Cicada Slough (Chantui).
