Li Bai's most wonderful farewell poem is "Farewell to Uncle Yun, the school secretary at Xietiao Tower in Xuanzhou". This is Li Bai's uncle Li Yun who was the school secretary in Xuanzhou (today's Xuancheng). A classic farewell poem written when he was in Tiaolou. The poem does not directly write about farewell, but more expresses Li Bai's resentment at not being able to appreciate his talent. Although the poem is full of worries and anguish, it is not gloomy and gloomy. The song-like expression, the strong ups and downs of thoughts and emotions, are deeply rooted in people's hearts.

At the beginning of the poem, it can be seen that Li Bai was very depressed at the time, so that when he saw his uncle Li Yun, he vented his full turmoil. At the same time, it also reflects the bitterness of Li Bai's ten years of wandering in the world after he served as a scholar in the Hanlin Academy at the beginning of Tianbao. Because he was not taken seriously politically, he abandoned his official position and left. This kind of depression and sentimentality of being a guest in a foreign country is reflected in the Xie Tiao Tower today. Finally I can spit it out.

The next two sentences of "Peng Lai" are the poet praising himself and Li Yun. Li Bai praised Li Yun's article with "Jian'an Bone" for his strong style. ?Cut the knife to cut off the water, the water will flow more, raise a cup to relieve the sorrow, the sorrow will become more sorrowful?, should be the most familiar verse in this poem. The sentence "drawing a knife" is a metaphor for the inability to relieve the depression in the heart. The poet's words and sentences are unique and creative. The sentence "raise a glass" at the back even expresses this depressing mood that is compounded by sorrow. Nowadays, the word "sorrow" varies from person to person. It can be said to include all the sorrows in life, and Li Bai describes all the sorrows in this sentence.

The last two sentences are the poet's passionate words when facing reality. Due to the long-term depression of being unable to achieve his goals, the poet had to find relief, and the way to relief was to "scatter the boat". Looking at Li Bai's poem, the twists and turns of thoughts and emotions are perfectly combined through the waves of artistic expression techniques, making people read it with profound charm, and it has reached the realm of boldness and natural harmony. People in the Ming Dynasty commented on this poem: The sky is flying, the dragon is coming out of the sea?.
