Traditional virtues of prenatal education stories

Yes, there is a story in Saint Amethyst, "When you are four years old, you can make pears", which refers to the story that Kong Rong gave his brother a big pear when he was a child and taught the children to respect his brother. When Cao Cao sent people to arrest the Kong Rong family, someone tried to help his two young sons escape, but one of them famously said, "My Lord, you can't see there are no eggs under the nest". Finally, Kong Rong's family was killed.
