When Yen Ho was about to take up
his duties as tutor to the heir of Ling, Duke of Wei, he went to Chu Po Yu for
advice. “I have to deal, “ he said, “with a man of depraved and murderous
disposition….How is one to deal with a man of this sort?” “I am glad,” said Chu
Po Yu, “that you asked this question….The first thing you must do is not to
improve him, but to improve yourself.”
