子曰：“学而时习之，不亦说乎？有朋自远方来，不亦乐乎？人不知而不愠，不亦君子乎？”
The Master said, “Is it not pleasant to learn with a constant perseverance and application?”
“Is it not delightful to have friends coming from distant quarters?”
“Is he not a man of complete virtue, who feels no discomposure though men may take no note of him?”
