Du Fu also appreciated Li Bai's poems and wrote a poem for him. What is the whole poem?

Li Bai recalled in the spring that Du Fu's poems were invincible and full of thoughts. Fresh in Kaifu, Junyibao joined the army 1. Chunshu in Weibei, Muyun II in Jiangdong. When is a bottle of wine, heavy and thin paper 3? 1. Yu Kaifu: Yu Xin. Because he was an ancient general of a title of generals in ancient times and the third division of Kaifu instrument in the Northern Zhou Dynasty, he was called Yu Kaifu. Bao: Bao Zhao and Liu joined the army as the former Jingzhou Army. Yu and Bao were both famous poets in the Southern and Northern Dynasties, and Du Fu appreciated them very much. Therefore, Li Bai's poems are fresh as Yu Xin and elegant as Bao Zhao. 2. Weibei: The north bank of Weihe River refers to Chang 'an area, and Du Fu was at this time. Jiangdong: It refers to the south of Jiangsu Province and the north of Zhejiang Province today, when Li Bai was here. These two sentences, which contain feelings in the scenery, are written about the fact that we live far apart and miss each other deeply. 3. Paper: On Poetry. Since the Six Dynasties, poetry has generally been called literature. This was done by Du Fu shortly after he arrived in Chang 'an in the fifth year of Tianbao (746) or the spring of six years. Du Fu and Li Bai broke up in Tianbaolu County for four years and never met again. The poem expresses Du Fu's deep friendship for Li Bai and his high praise for his literary talent. "General Introduction to Tang Shilin" quotes Yi language: "The word" floating in the air and thinking without group "is also the god of white". This poem is also quite appreciated by predecessors. Poetry in Tang and Song Dynasties called it "a pun on the scene, what's the meaning?" "Tang Poetry" calls it "writing scenery without feeling." The friendship between Du Fu and Li Bai was first formed from poetry. The Five Laws of Remembering Li Bai was written by Du Fu when he lived in Chang 'an in the fifth year of Tianbao (746) or the sixth year of Tianbao (747), mainly from this aspect. The first four sentences, all in one breath, are enthusiastic praises to Li Bai's poems. The first sentence praised his poems as the best in the contemporary era. The second sentence is an explanation of the previous sentence, which means that the reason why he "has a way in his poem" lies in his extraordinary thoughts and interests, so his poems are unparalleled. Then praise Li Bai's poems as fresh as Yuxin and elegant as Bao Zhao. Yu Xin and Bao Zhao were both famous poets in the Southern and Northern Dynasties. Yu Xin was called Yu Kaifu in the Northern Zhou Dynasty, from the official to the generals in title of generals in ancient times and the three divisions of Kaifu instrument (Sima, Situ and Sikong). Bao Zhao, then joined the former Jingzhou Army, which the world called Bao joined the army. These four sentences are full of enthusiasm. The two auxiliary words "ye" and "ran" in the first couplet not only strengthen the tone of praise, but also add the weight of "invincible poetry" and "unconventional". Du Fu is full of praise for Li Baiqi's magnificent poems, whether he presents them or remembers them. From the frank praise of this poem, we can also see how much Du Fu admired Li Bai's poems. This not only expressed his love for Li Bai's poems, but also reflected their sincere friendship. In Qing Dynasty, Yang Lun commented on this poem and said, "The first sentence is naturally that I have read through all the difficulties and hardships, and I am willing to give up my local language. DUZH can't be listed among poets who steal from ancient times and modern times; But Taibai's genius is far behind, and Du Fu can't overwhelm it, so he is particularly convinced, and often the articles are nothing. " (Du Shi Jing Quan) This statement is quite right. These four sentences are about remembering people and their poems, and hymns are about remembering people. But the author didn't know what this meant, but wrote "divorce" through the third link, which naturally added. This treatment is not only concise, but also avoids straightforward narration, which makes the poems interlocking and tortuous. On the surface, the last two sentences only describe the scene of the author and Li Bai. "Weibei" refers to the Chang 'an area where Du Fu is located; "Jiangdong" refers to Jiangsu and Zhejiang where Li Bai roams. "Spring Tree" and "Sunset" are just plain descriptions without any modification. Looking at it separately, the two sentences are very general, and there is nothing strange. However, the author organizes them in a joint, but naturally there is a wonderful close connection. That is to say, when the author misses Li Bai in Jiangdong in Weibei, it is also the time when Li Bai misses the author in Weibei in Jiangdong; The author looked at the southern sky, but only saw the clouds on the horizon. Li Bai looked at the northland from afar and only saw the colors of trees in the distance. Naturally, he saw their parting hatred, like "Spring Tree" and "Twilight Cloud", with a deep feeling of parting. Therefore, Huang Sheng in Qing Dynasty said, "Five fables recall each other, and six sentences recall each other." Both poems imply the same infinite feelings of both sides. How rich the memories of all the good times together, the situation after their separation and the various situations at this time should be. These two sentences seem dull, but in fact they are tempered every word; The language is simple, but rich in meaning, and it is a famous sentence that has been sung all the time. In the Qing Dynasty, it was called "Writing Scenery without Feeling" (Tang Poetry), and in the Ming Dynasty, Du Yi quoted Wang as "a work of ignorance", which was greatly appreciated. The above feelings of parting are written deeply and strongly, which naturally leads to the ardent hope of the later couplets: when can we meet again, as in the past, talk about wine and poetry! Talking about wine in the poem is the most memorable and desirable thing for the author, and the conclusion coincides with the beginning of the poem. The word "heavy" means that it used to be like this in the past, which made the disappointment of not seeing each other more distant and deepened the memory of friends. Taking "dang" as the tone of the question expresses the desire for an early reunion more strongly, making the ending endless, making people read the whole poem, and the author's infinite thoughts are still echoed in his heart. In Qing Dynasty, Pu Qilong said: "This poem is purely about poetry" (Reading Interpretation), which truly shows the content and structural characteristics of this poem. It is natural that the whole poem begins with a poem and ends with "paper", from poem to person, from person to poem, and turns around. The word "memory" runs through the whole poem, blending the admiration and nostalgia for people and poetry. The lyrical technique of scenery is even more superb, and the author's feelings of missing are deeply written.
