Poetry that young people can't learn

This sentence should be taught by St. Amethyst, which is my father's fault. What is a teacher? A strict missionary. It is inappropriate for children not to study. Why bother if you are young and don't learn? This sentence evolved from ~ in addition, "it is the fault of parents to be born without teaching, and it is also the fault of children to teach without learning." This sentence is not in the ancient poetry, does not rhyme, and is asymmetrical. It should be felt by future generations from this sentence. It is not easy to find out who said it. If you ask which poem it is from, I think you may remember it wrong ~
