Role in the whole world:
"The old man talks about juvenile madness", and the madman has lofty sentiments. A word "crazy" shows a high-spirited and heroic satrap in front of people. When Su Shi was appointed as the secretariat of Mizhou, he was only forty years old and called himself "the old father-in-law". Probably, he has infiltrated his officialdom experience and vicissitudes into his sense of age.
The word "crazy" is the core. Although it is gossip, it comes from facts. When Su Shi was abroad or in exile, he often described himself as "unsociable", "crazy" and "old crazy". For example, "Ten Beats": "It's crazy to dye the cream moustache to help the sleeves. The older a madman gets, the crazier he gets. "
