Appendix:
Ye Zhi's When You Are Old (translated by Yuan Kejia);
When you are old, gray-haired and sleepy,
Take a nap by the fire, please write down this poem.
Read slowly and recall the tenderness of your eyes in the past.
Recall the heavy shadows of their past;
How many people love you when you are young and happy,
Worship your beauty, hypocrisy or sincerity,
Only one person loves your pilgrim soul,
Love the painful wrinkles on your aging face;
I hung my head, by the red fire,
Whispering sadly about the passing of love,
On the mountain overhead, it walked slowly.
A face is hidden among a group of stars.
