1. Describe in time: what the poet saw in an autumn evening. "The homing bird, although tired, still carries the setting sun back." The tired bird wants to go back to its nest. At that time, it was getting late. The afterglow of the setting sun shines on the backs and wings of birds, as if carrying the setting sun back to its nest. The evening scenery, in the poet's pen, has a sad beauty.
2. Described in space: "When the wings are turned over, the setting sun falls on the river". The poet only paid attention to the birds in the sky and the sunset shining on them. As the birds' wings turned, they noticed the reflection of the sunset on the river. The reflection of the sunset seems to have fallen from a bird's wing. The last sentence, "The reeds with white heads are also made into a moment of beauty." The poet turned his eyes from the river to the reeds by the river, which is another transformation of space. From the wings of birds to the river, and then to the reeds, it constitutes a beautiful picture on the river at dusk in autumn.
Generally speaking, when the poet conceived this poem, he took the time sequence as "Jing" and spatial order as "Wei" and wrote the autumn evening scenery. When describing, you can either press chronological order or press spatial order.
