凡欲要儿子生，吉良日交会之，日常避丙丁及弦望、晦朔、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，非止百倍损于
父母，生子或喑哑、聋聩、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，冢墓尸柩之傍，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，祥瑞兢集。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，家道灭亡。夫祸福之验，有如影响，此乃必然之理，何不再思之。
凡男女受胎，皆以妇人绝经一日、三日、五日为男，仍遇月宿在贵宿日。又以夜半后生
气时泻精者，有子皆男，必寿而贤明高爵也。若以经绝后二日、四日、六日泻精者皆女。过
六日皆不成子，又遇旺相日尤吉。

与上件月宿日合者佳。论曰∶夫人求子者，服药须知次第，不可不知。其次第者，谓男
服七子散，女服荡胞汤及坐导药，并服紫石门冬丸，则无不效矣。不知此者，得力鲜焉。
Whenever one desires to conceive a son, sexual intercourse should be performed on auspicious days and favorable hours. One should generally avoid Bing (丙) and Ding (丁) days (Heavenly Stems associated with Fire), as well as the days of half-moon (Xian 弦), full-moon (Wang 望), last day of the lunar month (Hui 晦), and first day of the lunar month (Shuo 朔). Additionally, avoid conditions such as strong winds, heavy rain, dense fog, extreme cold, extreme heat, thunderstorms, lightning bolts, dimness of heaven and earth, lack of light from the sun and moon, appearance of rainbows, earthquakes, and solar or lunar eclipses. Conceiving during these times not only causes hundredfold harm to the parents but may also result in children who are mute, deaf, intellectually disabled, insane, suffering from spasms or lameness, blind or visually impaired, prone to illness, and short-lived, potentially leading to unfilial and unkind behavior. Furthermore, one must avoid intercourse under the sun or moon, in bright light, under stars, within temples or Buddhist shrines, near wells or stoves, beside latrines, or next to tombs and coffins; all such situations are strictly prohibited. If intercourse is conducted according to proper methods, virtuous individuals possessing great fortune, wisdom, and goodness will descend into the womb, thereby making the parents' temperament and conduct harmonious and compliant, ensuring their endeavors succeed harmoniously, the family prosperity increases daily, and auspicious signs gather continuously. Conversely, if improper methods are used, individuals lacking fortune, intelligence, and virtue will descend into the womb, causing the parents' temperament and conduct to become fierce and dangerous, their endeavors to fail, the family fortune to decline daily, and misfortunes to occur repeatedly. Even if the child grows up, the family line may perish. The verification of disaster and fortune is like a shadow following a form or an echo responding to a sound; this is an inevitable principle, how can one fail to reflect upon it again?
Regarding conception by both men and women, when ejaculation occurs on the first, third, or fifth day after the woman's menstruation ends, and coincides with the moon residing in an auspicious mansion, a male child will be born. If ejaculation takes place after midnight during the time when Yang Qi arises, the sons will invariably be male, destined to be long-lived, virtuous, wise, and hold high rank. If ejaculation occurs on the second, fourth, or sixth day after menstruation ends, female children will be born. Conception beyond the sixth day is unlikely to succeed. Encountering prosperous and thriving days is especially auspicious.
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 (Gui).

If Spring combines with Jiayin (甲寅) and Yimao (乙卯) days; Summer combines with Bingwu (丙午) and Dingsi (丁巳) days; Autumn combines with Gengshen (庚申) and Xinyou (辛酉) days; Winter combines with Renzi (壬子) and Guihai (癸亥) days. These combinations are excellent when aligned with the aforementioned lunar mansion days. The treatise states: For women seeking pregnancy, the sequence of taking medicine must be known and cannot be ignored. This sequence is: men take Qizi San (Seven Seeds Powder), women take Dangbao Tang (Uterus-Cleansing Decoction) and sit-induction medicines, along with Zishimen Dongning Wan (Purple Gate Winterberry Pills). In this manner, efficacy is assured. Those unaware of this will rarely achieve success.
