Why does Hu Shi like telling jokes about his wife?

Hu Shi's marriage was arranged by his mother, and his wife, Jiang Dongxiu, was an illiterate peasant with little feet, which was not commensurate with his social status and spiritual level. At that time, the atmosphere of free love had risen, but Hu Shi did not ruin the engagement like other young people. It is conceivable that after marriage, Hu Shi associates with friends and friends, and it is inevitable that someone will be wronged for him. Therefore, the joke of being afraid of his wife may also be a way for Hu Shi to laugh at himself and persuade his friends to leave.
