张石顽曰∶胎教之说，世都未谙。妊娠能遵而行之，不特无产难之虞，且生子鲜胎
毒殇夭之患，诚为广嗣要旨，姑以大概陈之。妇人经后四十余日不转，即谨房室，慎起居，
薄滋味，养性情，刻刻存心，与执持宝玉无异。举趾必徐，行立勿仰，坐不实其前阴，卧
勿久偏一侧，弗举手攀高取物，勿擎手沐浴篦头，不可看异形，不可独处暗室，毋登高，
毋临深，毋移重，毋磋跌，忌耽坐嗜卧，使气血凝滞。虽不可负重作劳，然须时时小役
四体，则经络流动，胎息易于运动，腰腹渐粗。饮食不宜过饱，茶汤更须节省，大热大
凉，总非所宜。犬羊蟹鳖等一切有毒之物，固宜切禁，即椒姜常用之品，亦须少尝。其豕
肉醇酒湿面之类，纵不能摒绝不食，亦不可恣啖。归精于胎，过于蕃长，致母临蓐难产。
而子在胞中，禀质肥脆，襁褓必多羸困。即如沃壤之草木，移植 土，枝叶得不凋委乎？
甫交三月，即当满裹其腹。胎气渐长，仅可微松其束，切勿因其气急满闷而顿放之。在
夏洗澡，须避热汤。冬时寤寐，勿迫炉炭。其最甚者，尤在不节交合，淫火尽归其子，以
酿痘疹疥癞之毒。然须妊娠禀性安静，不假强为，方遵实济。若强制以违其性，则郁火
弥炽，此与恣情无禁者虽截然两途，而热归胎息则一。尝见有切于求嗣者，得孕即分处
房帷，而子仍殁于痘，岂非强制，其火弥炽之明验乎？盖人之志欲匪一，苟未能超出寻
常，又须曲体母情，适其自然之性，使子气安和，是即所谓胎教也。当知胎教原非一端，
若怀子受惊则子多胎惊。怀子抱郁，则子多结核流注。怀子恐惧，则子多癫痫。怀子常
起贪妄之念，则子多贪吝。怀子常挟愤之心，则子多暴狠。怀子常造绮语诡行，则子多诈
伪。非但怀子之后，当检束身心，而经净交感，慎毋恣肆，以遗胎息之患。若大醉后媾
精，精中多着酒湿，则子多不育。大怒后媾精，精中多挟怒火，即子多乖戾。大劳后媾
精，精中不满真气，则子多孱弱。若夫热药助战，作意秘精，精中流行毒悍，则子多异
疾。至于风雨雷电媾精，感触震气，则子多
怪类。以此言之，则三元五腊，宜确遵禁戒，诞育自是不凡。宗祧重务，安得视为嬉戏哉？
张石顽说：胎教的理论，世人大多不了解。如果妊娠期间能遵循并实行这些原则，不仅没有难产的担忧，而且孩子也很少会有胎毒、夭折的祸患，这确实是广继后嗣的关键要点，姑且将大概情况陈述如下。妇女月经结束后四十多天（即怀孕初期），就要谨慎节制房事，小心起居生活，饮食清淡少滋味，调养性情，时刻用心注意，就像手持宝玉一样小心翼翼。抬脚一定要缓慢，行走站立不要仰头，坐着时不要压迫前阴部位，睡觉不要长时间偏向一侧，不要举手攀高取物，不要高举双手沐浴或梳头，不可观看奇形怪状的事物，不可独自待在黑暗的房间，不要登高，不要靠近深水，不要搬移重物，不要磕碰跌倒，忌讳久坐嗜卧，使气血凝滞。虽然不能负重劳作，但必须时常轻微活动四肢，这样经络流通，胎息易于运动，腰腹逐渐变粗。饮食不宜过饱，茶和汤更要节省饮用，大热和大凉的食物，总归都不适宜。狗肉、羊肉、螃蟹、鳖等一切有毒性的食物，固然应该严格禁止，即使是花椒、生姜这些常用物品，也必须少量品尝。猪肉、醇酒、湿面之类，纵然不能完全摒弃不吃，也不可放纵大吃。精气都归于胎儿，导致胎儿长得过于肥大，致使母亲临产时难产。而孩子在母体胞宫中，禀受体质肥嫩脆弱，婴儿期必定多有瘦弱困顿。这就如同肥沃土壤上的草木，移植到贫瘠土地上，枝叶能不枯萎吗？刚满三个月，就应当用布带紧紧包裹腹部。胎气逐渐增长，只能稍微放松束缚，千万不要因为孕妇感到气急胸闷而立刻解开。夏天洗澡，必须避开热水。冬天睡眠时，不要靠近炉炭取暖。其中最严重的，尤其是不节制性交，淫火全部归于儿子，从而酿成痘疹、疥疮癞病等毒素。然而必须要求妊娠者本性安静，不假意强行做作，才能切实见效。如果强制违背其本性，那么郁结之火更加炽盛，这与放纵情欲不加禁忌的人虽然途径截然相反，但热邪归于胎息是一样的。曾见过有人迫切求子，得到怀孕后就分居卧室，但孩子仍然死于痘症，这难道不是强制导致火势更盛的明显验证吗？大概人的志趣欲望不一，如果不能超出寻常境界，又必须曲意体谅母亲的情感，顺应其自然的本性，使胎儿气息安和，这就是所谓的胎教。应当知道胎教并非只有一方面，如果怀孕期间受到惊吓，则孩子多患胎惊。怀孕期间怀抱忧郁，则孩子多患结核流注。怀孕期间恐惧，则孩子多患癫痫。怀孕期间常起贪婪妄想之念，则孩子多贪婪吝啬。怀孕期间常挟带愤恨之心，则孩子多暴躁凶狠。怀孕期间常造绮语诡行，则孩子多欺诈虚伪。不仅是怀孕之后，应当检束身心，而且在月经干净后交合，务必不要放纵肆意，以免遗留给胎息的祸患。如果在醉酒之后受孕，精液中多含有酒湿，则孩子多不育。在暴怒之后受孕，精液中多挟带怒火，则孩子多乖戾。在大疲劳之后受孕，精液中不满真气，则孩子多孱弱。如果用热药助兴，刻意秘精，精液中流行毒悍之气，则孩子多患奇异疾病。至于在风雨雷电中受孕，感触震气，则孩子多怪异类人。这样说起来，那么在三元五腊（道教节日）期间，应当严格遵守禁戒，诞育自然不凡。宗庙继承的重任，怎么能视为嬉戏呢？
Zhang Shiwan stated: The theory of prenatal education (Taijiao) is largely unknown to the world. If one can follow and practice it during pregnancy, not only will there be no fear of difficult labor, but the child will also rarely suffer from fetal toxins or premature death. This is indeed a key principle for ensuring abundant offspring. I shall briefly outline the general principles. When a woman’s menstruation has ceased for more than forty days (indicating early pregnancy), she must strictly abstain from sexual intercourse, be cautious in her daily routine, consume bland food with mild flavors, nurture her temperament, and remain constantly mindful, handling herself as carefully as if holding a precious jade. She must lift her feet slowly, avoid looking up while walking or standing, avoid sitting in a way that compresses the anterior yin area, avoid sleeping on one side for long periods, avoid raising hands to climb high or fetch objects, avoid raising hands high while bathing or combing hair, avoid viewing strange or bizarre sights, avoid staying alone in dark rooms, avoid climbing heights, avoid approaching deep water, avoid moving heavy objects, and avoid tripping or falling. She should beware of excessive sitting or lying down, which causes stagnation of Qi and blood. Although she should not engage in heavy labor or carry heavy loads, she must frequently perform light exercises of the four limbs so that the meridians flow smoothly, fetal respiration moves easily, and the waist and abdomen gradually thicken. Diet should not be too full; tea and soup should be consumed sparingly. Foods that are extremely hot or cold are generally unsuitable. All toxic substances such as dog meat, mutton, crab, and soft-shelled turtle must be strictly prohibited. Even commonly used items like Sichuan pepper and ginger should be tasted only in small amounts. Pork, strong wine, and damp wheat noodles, although perhaps not entirely abstained from, must not be eaten indiscriminately. If the essence is overly concentrated into the fetus, causing it to grow excessively large, it may lead to dystocia at delivery. Meanwhile, the fetus within the womb, having inherited a fat and fragile constitution, will likely be weak and frail in infancy. This is akin to plants growing in fertile soil being transplanted to barren land; will their branches and leaves not wither? By the third month, the abdomen should be tightly wrapped. As fetal Qi grows, the binding may be slightly loosened, but it must never be completely released due to shortness of breath or chest distension. In summer, bathing must avoid hot water. In winter, sleep should not be near charcoal stoves. The most severe violation is particularly the lack of restraint in sexual intercourse, where lustful fire is transferred entirely to the son, brewing toxins that manifest as smallpox, rashes, scabies, or leprosy. However, this requires the pregnant woman to have a naturally calm disposition; if forced artificially, it will not work. If one forces behavior contrary to her nature, the stagnant fire will burn even fiercer. Although this path is distinct from unrestrained indulgence, the result—heat returning to the fetal respiration—is the same. I have seen cases where individuals eager for offspring separated from their wives upon conception, yet the child still died of smallpox. Is this not clear evidence that forced abstinence intensifies internal fire? Human desires vary; if one cannot transcend ordinary limits, one must consider the mother’s feelings and adapt to her natural nature, ensuring the fetal Qi is peaceful and harmonious. This is what is meant by prenatal education. One must understand that prenatal education involves many aspects. If the mother is frightened during pregnancy, the child is prone to fetal fright. If the mother harbors depression, the child is prone to tubercles and flowing abscesses. If the mother is fearful, the child is prone to epilepsy. If the mother frequently entertains greedy or delusional thoughts, the child will be greedy and stingy. If the mother often harbors resentment, the child will be violent and fierce. If the mother engages in frivolous speech and deceitful actions, the child will be deceptive and hypocritical. Not only after conception must one restrain body and mind, but even after menstruation ends, intercourse must not be unrestrained, lest it harm the fetal Qi. Conception after heavy drunkenness introduces alcohol-dampness into the sperm, leading to infertility in the child. Conception after extreme anger introduces angry fire into the sperm, leading to perverse temperaments in the child. Conception after severe fatigue results in sperm lacking true Qi, leading to frailty in the child. Using hot medicines to aid sexual performance and deliberately retaining semen introduces toxic and harsh qualities into the sperm, leading to unusual diseases in the child. Conception during wind, rain, thunder, or lightning exposes the process to shock energy, leading to abnormal or strange characteristics in the child. Therefore, during the Three Yuan and Five La festivals, strict adherence to prohibitions ensures extraordinary offspring. The weighty duty of continuing the ancestral line cannot be treated as a game.
