Because medicine has become more and more developed, in the past, childbirth was the most difficult thing to have, so it is often a dilemma whether to keep big or small.
因为医学越来越发达了，以前生孩子最怕难产，保大还是保小经常是个两难选择。
But now it's not the same. With the development of medicine, people can prepare for pregnancy more scientifically. They live in hospitals with good medical conditions when they give birth. When they give birth, they exaggerate to say that they are not afraid of anything.
而现在不一样了，医学愈发发达了，人们也能更科学的备孕了，生产时住在医疗条件良好的医院，生孩子时，夸张一点说，真是天不怕地不怕了。
Because in the traditional cognition, the older the age, the worse the physical function, the worse the physical function, the more dangerous it is to have a child, so we should try to be early.
因为在传统的认知中，年龄越大，身体机能越差，身体机能越差，生孩子越危险，所以要尽量早。

在身体完全发育成熟的时候，十七八岁就可以结婚了，结婚后立马要孩子，二十岁左右，身体正值巅峰时，要孩子，生产会很顺利。
