When You Are Old is a poem written by William Butler Yeats in 1893. This is a passionate and sincere love poem, dedicated by Ye Zhi to his beloved Maud Gunny. When you are old. When you are old, your hair is gray and you are sleepy. ? Take a nap by the fire, take down this book. Read it slowly, dreaming of the gentle eyes. Your eyes used to have them, and their shadows were deep. How many people love your happy and elegant moments? Love your beauty with hypocrisy or sincerity. But there is one person who loves your pilgrim soul. Love the sadness on your aging face; ? Bend down by the glowing fireplace. Whispering a little sadly, how did love die? Walking on the mountains overhead? Hide his face among the stars. When you are old, white-haired, sleepy and dozing by the fire, please take this poem down and read it slowly, recalling the softness of your eyes and their heavy shadows in the past; How many people love the beauty, hypocrisy or sincerity of adore you when you are young and happy? Only one person loves your pilgrim soul and the painful wrinkles on your aging face. He hung his head and whispered sadly about the disappearance of love by the red fire. On the mountain overhead, he walked slowly, hiding his face among a group of stars.
