论述说：阳气施放、阴气化生，所以形成妊娠，如果遇到三阴经气交会的时候，多会生出女孩。但是怀孕三个月，称为始胎阶段，此时血脉尚未流畅运行，胎儿开始依照母体所见的形象而变化。这个时候男女性别尚未确定，所以现在在未满三个月期间，通过服药和方法，可以转令生出男孩。其方法是把斧头放在孕妇床下，让斧刃朝下，不要让人知道。如果担心不相信，可以让母鸡抱卵的时候，根据这个方法放在鸡窝下面，一窝孵出的全是公鸡。这虽然还没有经过试验，但也不可不知道。凡是受孕三个月，胎儿会随着外界事物而变化。所以古人设立胎教，能够让孩子善良长寿、忠孝仁义、聪明无病。大概需要在十月怀胎期间，经常看到美好的景象，不接近邪僻的事物，这才是真正的良好教育。如果有触犯伤害胎气的情况，治疗各有方法。根据徐之才逐月养胎伤胎等方剂，详细倒是详细了，但事情繁琐很少使用，所以没有闲暇收录。懂的人应当自己查阅，现在列出安胎方如下。

治疗妊娠期间素来有风冷，胎萎不长，或者失于调养，动伤胎气，多导致流产堕胎。常服以保护胎脏。

It is stated: Yang qi exerts and yin qi transforms, thus pregnancy is formed. When the three yin meridians converge, female offspring are more likely to be born. However, at three months of gestation, it is named "initial fetus" (Shi Tai), where blood vessels have not yet flowed smoothly, and the fetus begins to change its form according to what the mother sees. At this time, the sex has not yet been determined; therefore, by administering medicines and methods before the third month is complete, one can influence the birth of a male child. The method involves placing an axe under the pregnant woman's bed with the blade pointing downwards, without letting others know. For those who may doubt this, when a hen is brooding eggs, one can place a similar setup under the nest; all chicks hatched from that nest will be roosters. Although this has not been tested, it is knowledge one should not ignore. Throughout the first three months of conception, the fetus changes in response to external stimuli. Thus, ancients established prenatal education (Tai Jiao), which can result in children who are kind, long-lived, loyal, filial, benevolent, righteous, intelligent, and free from disease. It is essential to expose oneself to beautiful scenes within the ten months of pregnancy and avoid evil or perverse influences; this is true good education. If there are incidents that offend and harm the fetus, there are specific treatments for each case. According to Xu Zhicai's monthly fetal nourishment and injury prescriptions, they are detailed but cumbersome and rarely used, so there is no space to record them here. Those knowledgeable should consult them themselves. Now, the following formulas for stabilizing the fetus are presented.
For treating cold womb causing abdominal pain during pregnancy, or heat in the womb causing frequent fright, lower back pain from lifting heavy objects, abdominal fullness with uterine tension, sudden vaginal bleeding, or injury from falling and twisting, poisoning from food or substances, or contracting seasonal diseases with alternating chills and fever, leading to damage to the fetal organ.

Glutinous Rice (Nuomi, 2 he)
Grind into a coarse powder. Take 4 qian per dose, with 1.5 sheng of water, 5 slices of ginger, 1 jujube, and a little gold/silver foil. Decoct until reduced to 0.7 sheng, take before meals.
For treating pre-existing wind-cold during pregnancy, fetal atrophy and poor growth, or neglect in care leading to disturbance of fetal qi, often resulting in miscarriage. Regular use protects the fetal organ.
Atractylodes Macrocephala Rhizome (Baizhu)
Chuanxiong Rhizome (Chuanxiong) (4 liang each)

Grind into a fine powder. Take 2 qian per dose, mixed with warm wine or rice gruel as desired. If abdominal pain occurs, add White Peony Root (Baishao); if severe pain in the epigastrium, add Chuanxiong; if irritability and vomiting occur, add Asarum Root (Xixin, 1 liang) and Pinellia Tuber (Banxia, 20 grains, washed with water). If thirsty, mix with barley juice. Even if the illness is cured, finish the course. If the taste is unpleasant and hinders appetite, it is suitable to make pills. This also treats leukorrhea and various diseases in unmarried women.
