According to Ancient Chinese Customs
It is believed that education starts in the womb (胎教 /Tai Jiao).
Once pregnant, a woman guards her thoughts carefully. She knows everything
she feels, smells, sees, hears, tastes, touches and does, will influence her unborn child. 
Whatever affects a woman’s mind/heart affects the unborn child in her womb. She practices character refinement by reading pleasant poetry, writing calligraphy and painting. She maintains composure and does not gossip, hurry or laugh loudly. 
She pays attention to details and does not look at harsh, contrasting colors or sit on a disheveled mat. She maintains a pleasing and orderly demeanor and refrains from losing her temper. 
She understands that a quiet mind/heart begets a healthy body (心 静 修 身) whereas a tumultuous mind/heart causes fatigue and harm (心 动 神 疲).
In the evening she reads beautiful stories before drifting off to sleep…
Thus laying the solid foundation for the future of her child under her guidance
and wisdom. 
Once pregnant, she studies and writes one Chinese character a day…
