A weak crown makes a gentle man, and a good reader of books. Poem on History I, written by Zuo Si, a poet in the Western Jin Dynasty, is weak and gentle, and stands out from other books. On the quasi-"Guo Qin", he wrote "Zi Xu". The border town is bitter, and the feather flies to Kyoto. Although I am not an armorer, I have read "Mao". The whistling stirs the breeze, and if there is no Soochow. The lead knife is expensive to cut, and the dream is better. The left is prosperous in Jiangxi and Hunan, and the right is looking forward to Qiang Hu. I won't be knighted if I succeed, and I will return to Tian Lu for a long time. Appreciation of Zuo Si was an outstanding writer in Taikang period of Western Jin Dynasty (28-289). His achievements in poetry and fu are very high. "Sandu Fu" makes "Luoyang paper more expensive". Xie Lingyun thinks that his poems are "difficult to compare with ancient times" and Zhong Rong's "Poetry" is also listed as "top grade". Eight Poems on History is the representative work of Zuo Si's poems, so Liu Xie said, "It is outstanding in Poems on History" (Literary Mind Carves Dragons and Tales). The poem "Ode to History" does not begin with Zuo Si. In the early years of the Eastern Han Dynasty, Ban Gu had a poem "Ode to History". However, the writing of this poem was only "to summarize this biography without any ornamentation", while Zuo Si's poem "Ode to History" was not to summarize some historical events and figures, but to chant. Therefore, He Chao said, "In fact, the title of" Ode to History "is to chant for the bosom. He also said: "Those who chant history are just praising it for its beauty, summarizing this biography without adding algae, which is also true. Too impulsive and too paranoid, this is another change. (The Secretary of Yimen Reading, Volume 46) He believes that Zuo Si's Poems on History is a variant of poems on history, but it is actually a new development of poems on history. Zuo Si's poem "Ode to History" expresses the poet's own ambition. However, due to the restriction of the door-to-door system, talented people who were born in poverty at that time had great ambitions, so they had no choice but to retreat and be a "master" who was content with poverty. This group of poems shows the changing process of the poet from actively entering the WTO to passively avoiding the world. This is the grievance of a frustrated, idealistic and talented intellectual in feudal society. The first poem about one's talents and wishes can be regarded as a preface to this group of poems. The first four sentences, write your own erudition. "A weak crown makes a soft man" means that when I was 2 years old, I was good at writing articles. "read a lot of books", write your own extensive books, and you will be outstanding in learning. These two sentences are actually mutual, which means: I was outstanding at the age of twenty, not only good at writing, but also well-read Du Fu's poem says: "Reading is like writing" ("Twenty-two Rhymes for Wei Zuocheng"), it is precisely because Zuo Si is well-read that he can be good at writing, and he can "write on Guo Qin and write Zi Xu". That is to say, writing a thesis is modeled on Guo Qin Lun, and writing a poem is modeled on Zi Xu Fu. On the Qin Dynasty, written by Jia Yi in the Western Han Dynasty, is a famous piece in his political theory. Zi Xu Fu, written by Sima Xiangru in the Western Han Dynasty, is a famous piece in Fu. Zuo Si's essays take their works as an example, which shows his knowledge and talent, which is quite conceited. "The border town cries the cymbals" four sentences, writing that he is also familiar with the military. "Singing the cymbals" is a signal of fighting. There was a war in the frontier, and urgent documents quickly spread to the capital. Here, it may refer to the war against Xianbei Shuneng Machinery Department and Sun Hao in 279 AD. "Jin Shu Wu Di Ji": "In the first month of spring in the fifth year of Xianning (279), Lu Shuai Shu was able to capture Liangzhou. Ugly, make the capture guard Wuwei satrap Malone hit it. ..... In November, Wu was cut down on a large scale ... In December, Malone rebelled against Lu Shuneng, broke it, cut it, and Liangzhou was flat. "The bonfire ignited. Although the poet is not a soldier, he has also read the Art of War of Sima Yi. He thinks that he has not only literary talent, but also military skills, and he should serve his country when the war breaks out. Four sentences, "Whistling and stirring the breeze", write your own ambitions and wishes. The poet roared loudly, howling in the breeze, and his ambition was heroic. Where did Soochow look? He thought, a dull lead knife, everyone hopes to have a cutting purpose. Even if he is inferior, he dreams of exerting his talents and realizing "good wishes". As for what is the poet's "good picture" and "Zuo Lang Cheng Jiang Xiang", he gave a concrete answer: destroy Dongwu in the southeast and pacify Qianghu in the northwest. After his success, he was not rewarded and retired to the countryside. The first two sentences express the meaning of "saying Wu in the south and Rong Di in the north" in Emperor Wu of Jin Dynasty. The last two sentences are exactly the spirit of Lu Zhonglian that he praised: "You will be rewarded for your achievements, and your integrity will be outstanding. As far as feelings are concerned, the former is magnificent and the latter is bleak. This complicated feeling is unified, which shows the poet's spirit of being eager to make contributions and not greedy for wealth. It should also be mentioned that the writing age of Eight Poems on History can be determined according to the following sentences: "Long whistling stirs up the breeze, if there is no Dongwu", "The left is a prosperous place, and the right is a prosperous place." In November, 279 (the fifth year of Xianning), Emperor Wu of Jin attacked Wu on a large scale, and in March, 28 (the first year of Taikang), Sun Hao surrendered. In the first month of AD 279 (the fifth year of Xianning), the Xianbei Tree Energy Machinery Department was attacked, and in December, it was greatly broken. Therefore, He Chao thought that "poetry was written by Emperor Wu, so it was called" Dongwu ". Liangzhou has been disturbed repeatedly, so the following cloud says, "Qiang Hu will be determined." ("Yimen Reading Secretary" Volume 46) It can be seen that eight poems on history were written before AD 279 (the fifth year of Xianning). Liu Xizai, a Qing Dynasty poet, said: "Zuo Taichong's Ode to History is similar in style. However, the poet's comments are expressed in images and do not make people feel boring. On the contrary, the vivid images and rich feelings in poetry have strong infectious power. This poetic spirit is heroic and emotional, and it is easy to remind people of Cao Zhi. Cao Zhi's poem says, "When you die in the national disaster, you will suddenly feel like returning home" ("White Horse"), "It is not my ambition to live idle, but I am willing to worry about the country" ("Miscellaneous Poems"). Cao Zhi's wish to go to disaster for his country and make contributions to his career was stifled by Cao Pi and his son, and he spent his unhappy life gloomily. Thank you sir, who left thinking that "the left is a prosperous Hunan and the right is a strong Hu", was ruined by the gate valve system at that time, so the poet angrily complained to the gate valve system.
