《产经》云∶凡儿生，身不收者死。儿生，鱼口者死，儿生股间无生肉者死，儿生颅破
者死，儿生阴不起者死，儿生阴囊白而后孔赤者死；儿生毛发不周者子不成，儿生头四破开
亦不成，儿生声四散亦不成。
凡新小儿有此诸相者皆不字长也。
凡诸生子男偃者不利妻，女伏者不列夫。
凡建日生子是谓北斗之子，男女皆不可起，自死。
《产经》云∶说曰∶生子男视日上，生子女视辰上，得吉，神良。将有王相立者，又不
终始相克，又太岁上神与日辰。上神相生者，则长寿，吉。若不相生者，自如。若如得凶，
将神困死，气上下相克者，即不寿。若将遇白虎者，子生便死。若遇朱雀得疾病，若遇腾蛇
母惊。
一云∶常以天魁加子本命上，太一从魁下皆为天杀也。在上为天杀，在下为月杀。下生
子为鬼吏乃杀。月杀下生子，为人臣贼害。
一云∶以直用神得青龙太常者，富。得太阴者，保家而已。得六合者，常有赏乐。得朱
雀者，常遇悬官。得勾陈者，数与人斗诤。得玄武者，数被盗。得腾蛇者，见惊惧，性多悲
忧。得天空者，性欺诞。得白虎者，不寿。
《产经》云∶经曰∶四下贱上之时，生男妨父，生女妨母，亡其先人，是孤子。
一云∶子生时不欲克其日辰，日辰克，大凶。以此辨之，此为要诀也。
一云∶《龙花经》曰∶必记初纳妇日，纳以甲乙而庚辛生子，大凶。干伤害父，支伤害
母，皆克日辰则俱害。
一云∶凡月杀日生子，不问男女皆妨父母，子不吉。月杀者，丑戌未辰，终而复始。
一云∶以神后加孩生时魁加父母年者，妨害二亲。
《产经》说：凡是婴儿出生时，身体蜷缩不能伸展的，会死亡。婴儿出生时，肛门像鱼嘴一样张开的，会死亡；婴儿出生时大腿之间没有生肉的，会死亡；婴儿出生时颅骨破裂的，会死亡；婴儿出生时生殖器不勃起的，会死亡；婴儿出生时阴囊发白而后孔窍发红的，会死亡；婴儿出生时毛发分布不均匀的，孩子发育不全；婴儿出生时头部四周裂开四瓣的，也发育不全；婴儿出生时哭声四处散乱无力的，也发育不全。
凡是新生儿有上述各种相状的，都不能抚养长大。
凡是建日出生的人，被称为北斗之子，无论男女都不宜起身活动，否则会自取灭亡。
《产经》说：解释说：生男孩要看太阳所在的方向，生女孩要看辰星（或时辰）所在的方向，如果得到吉利的位置，神灵保佑良好。如果有王相之气站立，又不始终相互克制，且太岁上的神将与日辰、上神相生，那么就会长寿，吉利。如果不相生，就顺其自然。如果遇到凶兆，将神被困死，气上下相互克制的，就不长寿。如果遇到白虎，孩子出生即死。如果遇到朱雀，会得疾病；如果遇到螣蛇，母亲受惊。
另一种说法是：通常以天魁星加在子本命宫之上，太一星从魁星之下，都称为天杀。在天为“天杀”，在地为“月杀”。在下方生子为鬼吏所杀。在月杀下方生子，被人臣贼害。
另一种说法是：以直用神遇到青龙、太常的，富裕。遇到太阴的，仅能保家而已。遇到六合的，常有赏赐欢乐。遇到朱雀的，常遇官司悬案。遇到勾陈的，多次与人争斗争吵。遇到玄武的，多次被盗。遇到螣蛇的，见到惊恐畏惧，性格多悲忧。遇到天空的，性格欺诈荒诞。遇到白虎的，不长寿。
《产经》说：经中说：在四下贱上之时，生男孩妨碍父亲，生女孩妨碍母亲，丧失祖先，成为孤儿。
另一种说法是：孩子出生时不希望克制其日辰，如果日辰被克，大凶。以此辨别，这是关键诀窍。
另一种说法是：《龙花经》说：必须记住初娶妇的日子，如果纳妇日是甲乙日，而庚辛日生子，大凶。天干伤害父亲，地支伤害母亲，如果都克制日辰则共同受害。
The *Chan Jing* (Classic of Childbirth) states: If a newborn's body is curled and cannot extend, the child will die. If a newborn's anus opens like a fish's mouth, the child will die; if there is no flesh between the thighs at birth, the child will die; if the skull is fractured at birth, the child will die; if the genitals do not erect at birth, the child will die; if the scrotum is white but the orifice is red at birth, the child will die; if the hair distribution is uneven, the child is malformed; if the head splits open into four parts at birth, the child is also malformed; if the cry is scattered and weak at birth, the child is also malformed.
Any newborn exhibiting these various signs will not survive to adulthood.
If a male infant is born lying on his back, it is unfavorable for the wife; if a female infant is born lying on her stomach, it is unfavorable for the husband.
Those born on the Jian day are called Children of the Big Dipper. For both males and females, rising from bed is inadvisable, as it may lead to self-destruction.
The *Chan Jing* explains: When giving birth to a boy, observe the direction of the Sun; when giving birth to a girl, observe the direction of Chen (the Dragon hour/star). If auspicious positions are obtained, divine protection is good. If Wang (King) or Xiang (Minister) Qi stands firm, without mutual destruction throughout, and the Shen (Deity) above Tai Sui (Grand Duke Jupiter) generates with the Day and Chen, the child will live long and be auspicious. If they do not generate each other, let nature take its course. If inauspicious signs appear, trapping the Jiang Shen (General Deity), and Qi clashes mutually above and below, the child will not live long. If encountering Bai Hu (White Tiger), the child dies upon birth. If encountering Zhu Que (Vermilion Bird), the child will suffer from illness; if encountering Teng She (Flying Snake), the mother will be startled.
Another version states: Usually, placing Tian Kui (Heavenly Key) above the Zi (Rat) natal palace, and Tai Yi (Supreme One) below Kui, constitutes "Tian Sha" (Heavenly Killing). In heaven, it is Tian Sha; on earth, it is Yue Sha (Monthly Killing). Giving birth below leads to death by ghost officials. Giving birth under Yue Sha leads to harm by treacherous subjects.
Another version states: If the Zhi Yong Shen (Directly Used Deity) encounters Qing Long (Azure Dragon) or Tai Chang (Great Constancy), the family will be wealthy. If it encounters Tai Yin (Great Moon), it can only preserve the household. If it encounters Liu He (Six Harmonies), there will be frequent rewards and joy. If it encounters Zhu Que (Vermilion Bird), there will be frequent legal troubles. If it encounters Gou Chen (Hooked Earth), there will be frequent disputes and arguments. If it encounters Xuan Wu (Dark Warrior), there will be frequent thefts. If it encounters Teng She (Flying Snake), one will see fear and dread, with a personality prone to sorrow and worry. If it encounters Tian Kong (Heavenly Emptiness), the personality will be deceitful and absurd. If it encounters Bai Hu (White Tiger), the person will not live long.
The *Chan Jing* cites the classic text: During times when the lowly oppress the noble, if a boy is born, he hinders the father; if a girl is born, she hinders the mother. They lose their ancestors and become orphans.
Another version states: It is undesirable for the child's birth time to clash with the Day and Chen pillars. If the Day and Chen are clashed, it is extremely inauspicious. Distinguishing this way is the essential secret.
Another version states: The *Long Hua Jing* (Dragon Flower Classic) says: One must record the day of the initial marriage. If the marriage day is Jia/Yi (Wood), and the child is born on Geng/Xin (Metal) days, it is extremely inauspicious. The Heavenly Stems harm the father, and the Earthly Branches harm the mother. If both clash with the Day and Chen, both are harmed.
Another version states: For any child born on a Yue Sha (Monthly Killing) day, regardless of gender, it hinders the parents, and the child is inauspicious. Yue Sha refers to Chou, Xu, Wei, and Chen, cycling repeatedly.
Another version states: Placing Shen Hou (God's Rear) over the child's birth hour, and Kui Star over the parents' natal year, will harm both parents.
