Three changes, as follows:
Sorrowful - uplifting - more sad.
The poem expresses the depression of wasted years and unrealized ambitions, praises the Han Dynasty articles, Jian'an style and the heroic spirit of Xie Tiao's poems, and finally reveals the negative mood of being born.
The beginning of the poem is very abrupt, because Li Bai was very depressed at the time, so as soon as he saw his uncle Li Yun (Li Hua) who could talk to him, he vented his full complaints. Li Bai was enshrined in the Imperial Academy at the beginning of Tianbao, but he was not taken seriously politically and was slandered by the powerful. After a short time, he abandoned his official position and lived a wandering life. The bitterness of the world over the past ten years, the depression and sentimentality of being a guest in a foreign country, have accumulated in my heart, and today I can finally let it out.
The two sentences "Changfeng" use the scenery to express emotions. On a crisp autumn day, looking at the wind carrying autumn geese, my spirit is refreshed, my worries are swept away, I feel that my mind and environment are at ease, and I drink to my heart's content The passion for high-rise buildings arose spontaneously.
The two sentences "Penglai" are written separately for the host and the guest. The style of the article praising Li Yun as "Jian'an Bone" is vigorous. "Middle" refers to Nan Chao; "Xiao Xie" refers to Xie Tiao. Because he is after Xie Lingyun (Da Xie), he is called Xiao Xie. Here Li Bai is comparing himself to Xiao Xie, showing his confidence in his own talents. The sentence "Everyone is full of joy, strong and full of joy, and wants to go up to the blue sky to see the bright moon" expresses the author's lofty ambitions.
The phrase "draw a knife" is used to describe the inner depression that cannot be resolved, which is strange and creative. The sentence "raise a glass" expresses his frustrated mood of frustration, which can only make him more depressed and sad. It also expresses the sadness of parting.
The last two sentences are the poet’s passionate words of dissatisfaction with reality. Li Bai suffered from unsatisfactory depression for a long time and had to seek another kind of transcendence, that is, "dispersion makes the boat flat". Although escaping from reality was not his original intention, the historical conditions at the time and his noble and indulgent character who did not want to join the others made it impossible for him to find a better way out.
