1. timely description: what the poet saw in the autumn night. "The bird that returned to its nest, though tired, still came back with the sunset." The tired bird wanted to go back to its nest. At that time, it was getting late. The afterglow of the sunset shines on the bird's back and wings, as if bringing the sunset back to its nest. The evening scenery, in the poet's pen, has a sad beauty.
2. Description from space: "Flap your wings and throw the sunset on the river". The poet only noticed the birds in the sky and the sunset shining on them. When the birds turned their wings, they noticed the reflection of the sunset on the river. The reflection of the sunset seems to fall from the wings of birds. The last sentence, "White-headed reeds are also made into beautiful moments." 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 "scenery" and spatial order as "action", and wrote the autumn night scenery. Description, can be in chronological order, also can press spatial order.
