Who can talk about the background and intention of the poem "Diao Zhang Ji"

This poem, written in the tenth year of Yuanhe (8 15), is a famous masterpiece in the history of literature. According to predecessors, after that, Han Yu was the first to respect Li and Du, with the greatest praise. People think that this poem is aimed at some people to praise Du Fu and suppress Li or "Li and Du Fu scorn each other". Jin people after the Five Dynasties compiled the Book of the Old Tang Dynasty, believing that Yuan Zhen was the initiator of Du Li's theory of superiority and inferiority. The hermit poem of the Han Dynasty further mentioned the "group of children" denounced by the poem, referring to Yuan Zhen and Bai Juyi: "Yuan Zhen commented on merits and demerits, first Du, then Li, but Han disagreed. The poem said that" the article is ridiculous and not self-sufficient "is also a micro-development." Since then, many people have talked about it. However, this is not the case. In fact, Yuan Zhen was the first person to talk to Li and Du. Twenty-one years earlier than Han Yu's poems, that is, in the tenth year of Zhenyuan (794), Yuan Zhen wrote "Qu Jiang Bai Yun for the Old Man", which already contained the sentence "Du Li is the enemy of poetry". In the 14th year of Zhenyuan (798), Han Yu's poem "Drunk to Stay in the East" contained the phrase "I hated each other because I read Li Bai's poems and Du Fu's poems in previous years". But in the eighth year of Yuanhe, Yuan Zhen wrote Preface to Du Jun's Tomb, which is the only document in the Tang Dynasty that theoretically analyzes the significance of Du Fu's poems. Among them, Li and Du Fu are mentioned again, which is really different: "The poet came, but there was no one. At that time, Li Bai of Shandong was also named after Qiwen, and people called him Du Li. Guan Yu's Yuefu poems are sincere and not as beautiful as Zi. " If the story is laid out at the end, the arrangement is greater than the rhyme, or there are thousands of words, and the words are vigorous and powerful, but the style is clear and deep, which is in line with the law. It is impossible for Li Shangyin to cross its barriers. What happened? "Bai Juyi's" Nine Books with Yuan Dynasty "was written in the tenth year of Yuan Dynasty, and it was suspected of being ridiculed by Du Li. The master of poetry is called Du Li. Li Zhi's works are full of curiosity, elegance is better than interest. Du Fu's poems are the most, which can spread to more than a thousand people. They are all perfect, so Li. The chapters of the new building and Shi Hao are only thirty or forty. " Duchamp, what about Du Fu? "Bai's original intention is to emphasize that the new Yuefu poetry" only songs make people sick ",not to belittle it in an all-round way. But the suspicion of "libel" is inevitable. Han Yu's poems are full of efforts to promote Du Li, and his so-called "group" and "slander" must also mean something. Qian Zhonglian's Collection of Solutions adds a cloud: "Although Ji was introduced from the Han Dynasty, his Yuefu poems are close to Yuan Bai, but not to Korea, so it is called in vain. "Yuan and Bai hold the theory, which can be used for reference, so Changli has the inspiration for this poem?" Whatever the reason for writing this poem, its artistic achievements are really commendable. This poem is bold and unconstrained, quite romantic style of Li Bai. Its imagination, exaggeration and metaphor are novel and interesting, but they are very appropriate, showing everyone's demeanor. Zhu Yizun's Criticism of Korean Poetry said: "On poetry is another tune. It is better to be old, others don't have the courage. " The Outline of Tang and Song Poetry quoted Wu Kaisheng as saying: "There is a magnificent view." The novelty of Korean poetry has always been praised by people. Zhao Yi's "Ou Bei Shi Hua" says: "A poet who is good at marveling must be tempered before he can achieve greatness. For example, Changli's words such as "grinding the sky with a huge knife" and "thundering with great power" are really thrilling, but what everyone sees is the way to beat rabbits with all one's strength. " Your Servant's Poems: "Qi Jie's words were suddenly invented by themselves". Han Yu commented on Meng Jiao's poems in "Commending Scholars": "Hard words are spoken in the air, and words are properly released". This language is often used by later generations to evaluate Han Yu's own poems.
