Classic Poem

“How can it be you that don't have any gray hair, though you have lived
for many years?” You have asked the question and I will give you an answer!
My children have gone far in learning. My wife is rich in her virtue!
My servants do what I wish and my king, who shuns corruption, protects us!
And in my city there are many noble men who through their deep knowledge,
have acquired calm, have become self-controlled,
and the choices they make in their lives are built on the quality of restraint!
