After hearing the flute, the poet touched his homesickness, so the third issue ended with the song "Folding Willow". The ancients folded their willows when they bid farewell, hoping for the return of their loved ones. It is said that "Liu" and "Li" are homophonic, so it is a farewell gesture to fold the willow. Chang 'an Baqiao Bridge is a famous farewell place, or a place where willows climbed and collapsed for farewell. The song "Broken Willow" is a sad farewell, and its voice is sad and bitter. At the end of Taikang in Jin Dynasty, the song of "breaking willow" was popular in Luo Jing, and there was a word of "bitter struggle". The Song of Folding Willow in the Northern Dynasty said: "When you get on the horse, you don't catch the whip, but you are against Yang Liuzhi; Sitting on the flute, worried about killing the traveler. " Probably all the lyrics are written according to the meaning of the song. Therefore, when the poet heard this song, he was homesick. Generally speaking, people who have lived abroad for a long time have nothing to do during the day, but it is easy to miss their hometown at dusk. People are often sentimental in spring and autumn. Folding willow is the crowning touch of the whole poem, and it also means "smelling flute". Three or four sentences describe the poet's own feelings, but they contradict others. Emphasizing "this night" is to talk to all people living in Luoyang city and put on airs to sum up the sentence "Who can't stand homesickness". This is the deduction of subjective feelings, not to say "I", but to see the deep affection and homesickness of "I".
The short quatrains of seven words can quite show Li Bai's style characteristics, that is, his subjective tendency in artistic expression. Loving one's hometown is a noble emotion, which is interlinked with patriotism. The poet's hometown is where he was born and grew up. As a part of the motherland, that image is especially unforgettable for poets. Li Bai's poem is about smelling the flute, but its significance is not limited to describing music, but also expresses his yearning for his hometown, which is its touching place.
The whole poem is a word "smell" to express his feeling of smelling the flute. The first sentence of this poem is a thinking question. The piper, who never showed up, just listened to himself, but unexpectedly touched many listeners. This is the meaning of the word "dark" in the sentence. The second sentence said that the flute was blown away by the spring breeze and spread all over Luoyang city. This is the poet's imagination and artistic exaggeration. The third sentence shows that the "broken willow" played by the flute from the spring breeze expresses the feeling of parting, so the next sentence says that which one can't be aroused by the emotion of missing hometown! It came to an abrupt end, so the aftertaste lingered in the reader's mind for a long time, which was memorable.
