At the beginning of the poem, there is an unavoidable contradiction that "the date of your return is uncertain" The hope of returning to China and disappointment in the future are opposites. Sorrow enveloped the whole article. On the surface, "it rains at night in the autumn pool" is an impromptu point. However, this scene makes the sadness of returning to China more vivid and rich. Bashan, alone in a foreign land, is autumn, late at night and rainy at night. The situation itself is very sad. In particular, the word "rising autumn pool", continuous autumn rain, filled the pool with water. The poet captured this beautiful and realistic picture and inspired the imagination of readers. It seems that what rises in the autumn pool is not autumn water, but the pain that the poet can't get rid of.
Although the quatrains are short, they also pay attention to structural skills. It has been said by predecessors that quatrains are generally difficult to inherit two sentences, and it is better to say them directly and calmly. Change takes a lot of time, all in the third sentence. The third sentence of this poem shows this kind of effort. "Why * * * Cut Candles at the West Window" jumps from now to the future, from Bashan to the north (Chang 'an), and writes the poet's reverie with the rhetorical method of expressing the present. "Cutting candles at the west window" may have melted the poetic meaning of "holding candles at night is more like a dream" in Du Fu's "Three Songs of Qiang Village", but it has changed from a couple to a friend and is more affectionate. The word "when" means "when will it be possible", and the first sentence "not yet" is done, which is both urgent and unpredictable. Emotionally, with the first two sentences, it seems to be broken
The fourth sentence is more exciting. Farewell to the Rain at Night comes from "* * * Cutting the West Window", which is a boat sailing down the river. In the genre of quatrains, which is as short as only four sentences, it is not a pity to use the meaning of repeated sentences, but it is bold. However, the reappearance of Late Rain is not monotonous, but its significance is tortuous and profound. If the "late rain" in the previous sentence is based on scenery, then the "late rain" in this sentence is based on feelings. It and Cut the Candle at the West Window form a warm and dynamic picture, which shows the poet's longing for the return date and his deep friendship with Jun. This adds joy to the poem. This joy is only an unpredictable expectation, so it shows the joy of the future and aggravates the pain of untimely return. We can feel the poet's mood constantly ups and downs, but the emotional tone is always harmonious and unified.
