Explanation:
The rain has stopped at night, but there is still a little coolness
There are no stars and no moon outside the window, but I can see the residual clouds reflected on the window
It's already late at night, but I can't sleep. It's as if I can hear the sound of flowers falling.
What can I do if I can't sleep? Lacrimosa
This poem is mainly about what the author has heard and seen after insomnia, and what is deep in his heart.
