What is Li Bai’s poem when he thinks that his whereabouts are uncertain and he doesn’t know when he will return to his hometown?

Jingye Thoughts

The moonlight shines brightly in front of the bed, which is suspected to be frost on the ground.

Look up at the bright moon and lower your head to think about your hometown.

The bright moonlight shines on the window paper in front of the bed, as if there is a layer of frost on the ground. I couldn't help but raise my head and look at the bright moon in the sky outside the window that day. I couldn't help but lower my head and think about my hometown far away. The poet looked up at the bright moon in the sky and felt homesick.
