This poem describes drinking with the moon. It was lonely to drink alone with the moon, but the poet used his rich imagination to weave the moon and his own figure into the so-called "three people." From the word "flower" to the word "spring", from the word "injustice" to "song" and "dance", the lonely environment is rendered very vividly, not only vividly with pen and ink, but more importantly, it expresses the poet's broad-minded character and his feelings of being good at self-resolving.
On the surface, the poet seems to really enjoy himself, but behind it is full of infinite desolation. Poets are lonely enough to invite the moon and the shadows, but not enough. Even in the later years, it is impossible to find someone to drink with. So I can only be friends with the figure in the moonlight forever, and meet again in the fairyland of heaven.
