议论说：人们都知道胎儿在胞胎中成形，出生养育都有固定的期限，约定俗成说是十个月足月而生。但探究其究竟的真理，其实以二百七十天为定论，从古至今难道有间断吗？
然而其中虚算月份，大约以九九（九个月）为上等，八八（八个月）次之，七七（七个月）又次之。人生禀赋于天地二仪之气，会合三才之道，各得其“九”。三乘以九得二十七，即二百七十天为正数。此时血气充盈，精神坚固平和，为人具足，相识、智性都通晓。
所谓“八八”者，是三才各得其“八”，三乘以八得二十四，即二百四十天。此时出生，血气荫护不及，精神有亏欠，为人拙劣谬误、鄙陋迟钝，智力意志容易遗忘。
所谓“七七”者，是三才各得其“七”，三乘以七得二十一，即二百一十天。此时所受胎气不足，为人狂愚无志，恶劣野蛮如狼戾。
这期间或有大大超过或不足的情况，都共同对应其正数。大大超过即气血荫护有余；不足则气血滋养不到。人得其中道，以为纯粹，阴阳得所，刚柔兼济，气血相和，百脉相顺，所以生下来人心智益加通晓，精神俱备，腑脏充实，形体固壮。医者只要观察婴孩的颅囟，就可以知道了。
未满周岁的婴儿，颅囟坚固闭合，眼珠黑亮，神气清明，口型方正，背部浓厚，骨骼粗壮，臀部丰满，脐窝深，肚子软，阴茎小，睾丸大，牙齿细密，头发润泽，声音洪亮，睡眠安稳。这是受气充足、禀赋得中而更优的表现。
一到三岁之间，如果囟门还大，头颅虚空旷达，额前凹陷如坑，口角宽阔，神气外露，胸部高耸，骨骼纤细，臀部削薄，脐部突起，头发枯黄，牙齿稀疏，睾丸小，阴茎大，呼吸急促，声音僵硬。这都是由于受气不足、怯弱所致，容易惊悸，智性难以通晓。
父母爱惜孩子，良医必定担忧。不论贫富贵贱所生，贤者应当以此告知。如果是愚鲁之人，宁可不用药，稍微用药刀不及之处，反而说医生杀死了孩子。
大凡初生孩子，少具备精神的，大多是由于夫妇之情未和谐，心意未绸缪，且喜且惊，神气不和脱失。将来得到适宜的环境，乐则情浓，动则情兴，惧则情思，交合则情极深，契合其意，重视美好，生男必温和，生女必淑静，可以知道淳和之至如此。
因此医家不可一概用药，宜斟酌轻重，比附推详，度究可否，不至恣意妄为，反为虚设，从而造成重害。参审得失的议论，尽善尽美，应机而已。
Discussion states: People all know that the fetus takes shape in the womb, and birth and nurturing have fixed terms, conventionally agreed upon as ten months of full-term gestation. However, exploring the ultimate truth, it is actually concluded at two hundred and seventy days as a fixed standard. Has this varied from ancient times to the present?
Yet, calculating by lunar months roughly, nine nines (nine months) is considered superior, eight eights (eight months) is next, and seven sevens (seven months) is again next. Human endowment derives from the Qi of Heaven and Earth, combining with the Way of the Three Powers (Heaven, Earth, Man), each obtaining "nine". Three multiplied by nine equals twenty-seven, representing two hundred and seventy days as the standard number. At this time, Blood and Qi are abundant, Spirit is solid and peaceful; the person is complete, with perception and intelligence fully developed.
Those born at "eight eights" correspond to the Three Powers each obtaining "eight"; three multiplied by eight equals twenty-four, representing two hundred and forty days. Born at this time, the protection of Blood and Qi is insufficient, and Spirit is deficient. Such individuals are clumsy, erroneous, vulgar, dull, prone to forgetting their intellect and will.
Those born at "seven sevens" correspond to the Three Powers each obtaining "seven"; three multiplied by seven equals twenty-one, representing two hundred and ten days. The fetal Qi received is insufficient at this time; such individuals are mad, foolish, lacking ambition, vicious, wild, and fierce like wolves.
Among these, there may be cases significantly exceeding or falling short of the norm, all corresponding generally to the standard numbers. Significantly exceeding means an excess of protective Blood and Qi; falling short means inadequate nourishment by Blood and Qi. Those who attain the Mean become pure, where Yin and Yang find their proper place, hardness and softness complement each other, Blood and Qi harmonize, and all vessels follow smoothly. Thus, they are born with enhanced mental acuity, complete Spirit, solid Zang-Fu organs, and robust physical form. A physician can discern this simply by observing the infant's fontanelle.
For infants under one year old, if the fontanelle is firm and closed, the eyes are dark and bright, the Spirit is clear, the mouth shape is square, the back is thick, the bones are coarse, the buttocks are full, the umbilicus is deep, the abdomen is soft, the penis is small, the testicles are large, the teeth are fine, the hair is lustrous, the voice is resonant, and sleep is steady. This indicates sufficient reception of Qi, balanced endowment, and even excellence.
Between the ages of one and three, if the fontanelle remains large, the skull feels hollow, the forehead sinks like a pit, the mouth corners are wide, the Spirit is exposed, the chest is high, the bones are thin, the buttocks are shrunken, the umbilicus protrudes, the hair is yellowish, the teeth are sparse, the testicles are small, the penis is large, breathing is rapid, and the voice is stiff. These result from insufficient reception of Qi and weakness, making them prone to fright palpitations and difficult to develop intelligence.
Parents cherish their children, and good physicians worry accordingly. Regardless of whether the child is born to rich, noble, poor, or humble parents, the virtuous should inform others of this. If dealing with ignorant people, one might prefer not to use medicine; if medical intervention fails slightly, they might falsely accuse the doctor of killing the child.
Generally, newborns lacking Spirit often stem from discord between husband and wife, lack of emotional preparation, mixed feelings of joy and fear, leading to disordered and scattered Spirit. If later provided with a suitable environment, joy intensifies emotion, movement stimulates passion, fear engenders contemplation, and sexual union reaches extreme depth, aligning with intent and valuing beauty. Sons will likely be gentle, daughters virtuous. Thus, the utmost purity and harmony can be understood.
Therefore, physicians must not apply medications uniformly. They should weigh severity, analogize and deduce carefully, assess feasibility, avoid reckless actions, prevent futile treatments, and thus avoid causing severe harm. Examining gains and losses, striving for perfection, and responding appropriately to the situation are key.
