Song of everlasting regret, which sentence is empathy for the scenery?

"He gazed at the desolate moon from his temporary palace, and he heard the bell beating on his chest in the late rain."

analyse

The moonlight is bright and the bell is beautiful, but in the feelings of Tang who misses Yang Guifei very much, it has changed its nature and become "sad color" and "heartbroken sound", which is undoubtedly the result of subjective feelings moving in. So the lyrical way of this sentence is empathy with the scene.
