From Li Bai's Reading Records in Tang Dynasty

Poetry: Luo Wei's scroll seems to have been opened. The bright moon goes straight in, with no intention of guessing.

Commentary: Luo Wei suddenly rolled over and sat up, as if someone had come in. A bright moonlight shines into the room, which can reflect my aboveboard feelings. There is really no doubt about it.

Analysis:

Since Luo Wei Shu Juan, there has been a dramatic change in poetry and painting: the fields are silent, but the poet is still alone in the empty hall. Who is he waiting for? The curtain by the door suddenly fluttered, as if someone had brought it in.

The poet turned around in surprise, only to find that the visitor had only a breeze. As the curtains are opened, the moonlight will enter silently, just like a generous friend who rushes in without saying hello-however, this is only an "unintentional" visit by moonlight, which has no meaning at all.
