Marry a woman many years younger than herself.

I remembered a passage in Su Dongpo's poem "A pear flower hits a begonia".

Now this poem is generally used as a famous sentence to praise the snow scene. But it is said that Mr. Dongpo wrote this poem in the background that Mr. Dongpo had an old friend whose hair and beard were all white, but he married a beautiful young concubine. So at the banquet on the wedding day, Su Dongpo wrote this poem, mocking his friend's age and marrying a delicate little lady, which delayed his youth.

This is a beautiful mistake in the process of cultural communication.
