Give children a free sky, which is what children want most.
A child can eat it and teach his right hand. The only people who can talk are men and women. As soon as a baby learns to eat food, he should be trained to hold it with his right hand. When children learn to speak, they should educate boys to respond quickly to the calls and instructions of their elders and let girls understand things.
("Book of Rites Internal Rules")
Less is nature, habit is nature. The moral quality and code of conduct that people develop when they are young are as firm as their innate temperament, and they are not easy to change all their lives.
Knowledge is the essence of many generations, so we should respect the culture of our elders (Confucius)
