There are many records of ancient educators attaching importance to prenatal education. For example, Yan Zhitui, a famous educator in the Northern and Southern Dynasties, listed "the method of prenatal education" in the second chapter of "Yan Family Instructions: Teaching Children". Zhu, a famous thinker and educator in the Southern Song Dynasty, advocated that human education should start from the womb in his educational monograph "Primary School". "Ancient women were pregnant, sleeping on their side, sitting on their side, standing upright, not eating evil, being upright and sitting upright. Seeing no evil color, hearing no sound. You can recite poems at night and get down to business. Only in this way can the child be described correctly and stand out. " It means that pregnant women have certain requirements on diet, sleep, sitting posture, watching and listening. Even at night, we should invite those who recite the Book of Songs and tell history to educate pregnant women so that the children born can be upright and outstanding. In essence, these are the specific requirements for pregnant women to carry out health care during pregnancy, enhance nutrition, provide a good external environment, and keep pregnant women in a good psychological state, thus having a positive impact on fetal development. They belong to clinical eugenics and environmental eugenics in modern eugenics ~
