Parents' thoughts affect the fetus.
Every thought of parents is the child's initial education. As the original, everything we say and do will affect the children as replicas. Only when we study hard can our children make progress every day.
It's never too late to learn sage education.
As long as we are willing to act, it is never too late. But if we wait until the child is born to study sage education, it will be a bit slow. Because internalizing the thoughts of sages into their own thoughts requires a process of digestion. In this process, the classics that the fetus hears and the parents have doubts may have a bad influence on it.
The classics of sages need parents to study together.
It is not advisable to listen to the sages' classics only for the fetus when parents don't study them. Because this will make the classic content received by the fetus contradict the parents' ideas, leading to the physical and mental division of the child after birth. Parents should study the classics of sages together to ensure that the information received by the fetus is consistent with the parents' ideas.
