Source: Xie Lingyun of the Southern Song Dynasty, "Eight Prefaces to the Collection of Poems by Prince Ye of the Wei Dynasty": "It is difficult to combine the four in the world: good times, beautiful scenery, enjoyment, and pleasure."
Two of the more famous sentences later were written by people from the Ming Dynasty. One is from Tang Xianzu's masterpiece "The Peony Pavilion", "It's a good time to be beautiful, but whose house is it to enjoy it?"; the other is from Tang Bohu's "A Cut of Plum Blossoms, Pear Blossoms Closed Deeply in the Rain" "No one can judge the pleasures" in "The Gate".
