First, compound words do not repeat. In the two sentences of the first couplet, the words "Jiang" and "Village" appeared twice. According to the requirements of general metrical poetry, it is forbidden to have compound words in the same association of chin and neck, and the sentences scattered in the first and second lines are not so strict, but they should be avoided as far as possible. Using a pair of compound words here has a light and elegant feeling, but it doesn't feel like a crime. This situation is very similar to that in legal sentences. Difficult sentences must be saved by difficult sentences, and compound words must be supplemented by compound words. Besides, there are two other overlapping words "everything" in the second sentence, so that the first two poems have no sense of support.
Second, the whole poem is closely coordinated. "beam" belongs to "village" and "gull in water" belongs to "river"; "Chess" is the inheritance of "Long Summer", and "fishhook" means "Qingjiang". Zhuan Xu's "going to the beam alone, kissing the gulls in the water", two words of "self" and two words of "phase" are all self-correcting; "Go", "Come" and "Near" are all right. Self-righting and mutual righting, reading is light and smooth. Two simple sentences in the neckline can best express the artistic conception of husband and wife's growing old together, respecting each other as guests and being stubborn.
Third, at the end of the sentence, it is a consistent feature of Du Fu's nostalgic poems.
