Appreciate the nostalgic empty songs and smell the flute, and the hometown is like a rotten ke.

Wendy's Fu: It refers to the Fu of Thinking of the Old written by Xiang Embroidery in the Western Jin Dynasty. Xiang embroidery and Ji Kang are good friends. Ji Kang was killed because he was dissatisfied with Sima Group. Xiangxiu passed by Ji Kang's former residence, and when he heard someone playing the flute, he couldn't help feeling sad, so he wrote "Thinking of the Old". The preface says: I passed Ji Kang by, and I remember him for writing this fu. Liu Yuxi used this allusion to commemorate the dead Wang, Liu Zongyuan and others. Turn: adverb, and vice versa. Rotten people: refers to the quality of Jin people. Wang Zhi went up the hill to chop wood. When he saw two boys playing chess, he stopped to watch. At the end of the game, the boy asked Wang Zhi why he didn't go. Wang Zhi was shocked to find that the handle of the axe had rotted. Back to my hometown, I haven't met anyone for a hundred years (see Story Club). Liu Yuxi used this story to express that the world is cold, the personnel are completely different, and returning home every other year is like a lifetime ago. The poet compared himself with the king and expressed his feeling of isolation after being exiled to Beijing for more than 20 years. The poem uses the rhetorical devices of allusions, and uses two allusions, Fu and Ren, to express the sadness of the poet's returning home.
