After the fall of the Southern Song Dynasty, the poet often missed the emperor's homeland, and in the cold autumn, he felt even more depressed. The poet moved to the creek pavilion and watched the scenery. His thoughts were all over the place, and he still lingered until sunset. I straightened my head and looked around, but I saw the early moon hanging on the tall trees; the cold breeze blew, as if I was half awake from the wine. The tall trees in the forest are sparse, the fallen leaves are falling, the fields are empty and lonely, and fireflies are flickering. The poet walks alone, feeling restless, and can only sit idle, bored and counting the little bits of light in the sky. At this time, he suddenly heard that the fishermen were singing late, but he didn't know where they started. The poet looked into the distance and saw a solitary lamp looming outside the pavilion, thinking that the fishing fire must be the place where the fishermen's songs were placed. The whole poem is written in a light and elegant way, creating a clear autumn night with clear wind, falling leaves and flowing fireflies, and distant songs and distant thoughts. The poet's loneliness, depression and frustration are reflected in the lines, and the poet's loneliness and anger are also hidden. And aloof. This poem is full of thoughts about the motherland and is not an ordinary sad autumn poem. In the poem, the poet fully expresses his feelings of loneliness, depression and wandering.
