Shan Lan and dusk float on the South Mountain, bathed in the afterglow of sunset, and birds fly back to their nests together. These two sentences are suitable for both movement and static, quietly writing the beautiful scenery of Nanshan, and moving a group of homing birds spreading their wings and soaring. These two sentences are not only a description of the scenery, but also a lyric poem, expressing the poet's heart song of catching birds in the forest and returning fish in the pond.
