This is a poem written by Chu Guangxi, a poet in the Tang Dynasty, in The Old Residence of Master Shen Yan.
The whole poem "The Old Residence of Master Shen Yan" is as follows:
You can't live in a quiet place, but you have no hometown.
Everyone knows that Pei belongs to the Swallow Hall.
The floating clouds return to the old ridge, and the moon sets to the west.
In the empty dusk, I always smell strange fragrance.
