When Lu Mengzheng was appointed deputy prime minister by Taizong, the second emperor of the Song dynasty, he was only in his thirties. One day at a ministerial meeting, he happened to walk past a man who was making a sarcastic remark about him, "Is that greenhorn the new deputy prime minister?"
Lu Mengzheng pretended not to have heard anything. But an associate of his heard it and got angry. He wanted to find out the man's name. Lu Mengzheng stopped him.
"It's better not to ask," Lu Mengzheng said. "If I know the man's name, I may never forget. If I don't, I have nothing to vex my mind."
