After a long drought,
I met an old friend in another country.
Wedding night,
Be number one.
Legend has it that these four sentences were written by Du Fu, and they are called "four happiness" poems, which sum up the four happiest happy events in life, hence the name. When people get married, they often put up a pair of couplets: three poems by Du Fu and the first chapter of Nan Zhou. "Du Fu's Three Sentences" refers to the third sentence "Wedding night" in Four Happiness. The first chapter of Nan Zhou refers to the first chapter of The Book of Songs, National Style and Nan Zhou, which is a poem describing the love between men and women.
