From Cui Hu's
崔护 (Tang dynasty)
《题都城南庄》:
去年今日此门中，
人面桃花相映红。
人面不知何处去，
桃花依旧笑春风 - 'This day last year, at this gate, her face and the peach blossoms set each other aglow. The face is gone, no one knows where; the peach blossoms still laugh in the spring breeze.' The poem gave rise to the idiom
人面桃花 (yearning for a lost beauty).
