Is there any classical Chinese that tells us not to spoil children?

And the appreciation of the ancients in China-don't spoil your children, don't abandon them when they fall.

Children are uncivilized by nature and easy to teach. They should work hard according to Confucius' words (don't work hard if you love) and don't spoil them to grow their own hearts. If children have bad habits and are difficult to teach, they should keep Mencius' words (if they can't be raised, they can't be raised), and don't give up and turn over a new leaf lightly.

When children's nature is not polluted, it is easier to teach them, so we should teach them according to what Confucius said: "Love can be gained for nothing", don't spoil him too much, and cultivate his unrestrained habit; When a child develops a bad habit, it is difficult to teach. Therefore, it is necessary to follow Mencius' saying that "if you can't cultivate Chinese, you can't cultivate talents" to educate him, and you can't give up easily, so he loses the opportunity to turn over a new leaf.

[Comment] Confucius said that the habits I developed when I was young were just like at the beginning; A long-term habit, just like before. As the saying goes, "Educating daughter-in-law should start from the moment she enters the door, and educating children should start from infancy." We shouldn't spoil children's education from the beginning, otherwise when the arrogant habit has formed, we will stop it, even if we exert great pressure, it is not easy to correct it.

And once a child's bad habits are formed, they cannot be left behind. . . . . . Teach them to be tolerant, kind, respectful and cautious. . . . . . If you persist in this way for more than ten years, you will naturally develop good ambitions and interests.
