His prose uses words to make sentences, which is approachable and light and powerful. The parallel prose of the famous "Humble Room Inscription", although only a few dozen words, shows a picture with charm, which not only entrusts Liu Yuxi's personal ideals and poetry, but also shows his optimistic spirit and natural open-minded mind. His political essay "Answer to Rao Shijun's Letter" is far-sighted and incisive, pointing directly at the bad habit of "keeping the disadvantages to the law" in officialdom, showing Liu Yuxi's unique views on politics; The book "Debate on Traces" about history is unique, and it discusses how to treat and objectively evaluate the achievements of historical figures by way of subject-object question and answer. The argument about "196" is well-founded and clear-cut. Generally speaking, his essays are clear-headed, logical, concise, rich in connotation and thought-provoking. They are handed down from generation to generation, showing us rich details in history, medicine, astronomy, music and so on.
In addition to his essays such as Riding the Dust, he also has a variety of styles such as Sao Fu, Narration and Monument, Annotation, Table, Shape, Enlightenment, Ming, Ji, Essays and Ode, among which there are many excellent works. Sao Fu includes Wen Da Gou Fu, Wen He Fu, Qiu and so on. These poems are beautiful and delicate, expressing Liu Yuxi's various emotions and reverie. Other categories include monuments, records, forms, forms, revelations, inscriptions, collections, miscellaneous works, carols, etc. Among them, his mourning articles for Han Yu and Liu Zongyuan are the most sincere and touching. The narrative "Kanpan" vividly depicts the bargaining situation, which shows that Liu Yuxi's observation of the market is meticulous and unconventional. Therefore, Li Ciming's "Reading the Secretary of the Auditorium" thinks that "Zhongshan narrates all the articles, which are concise and concise, and it is a child of its own." .
Liu Yuxi is very particular about words, and every word has a source. For example, "Returning to Japan" and "Returning to China" are used as "opposites" in The Story of Wuling North Pavilion, which is consistent with "Returning to China is inevitable and easy" in Xiaoya's poem. The words "don't blame Geng" and "Geng" as "compensation" in the wall of Lianzhou Secretariat Hall are in line with the annotation of "please Geng" in the Book of Rites. Huayang national records are used for loyalty and nine realms in the Note to the Crown Prince of Suzhou.
Many of Liu Yuxi's essays reflect social life and have great exhibition value, which is closely related to his philosophical thoughts. In the famous book "On Heaven", he first expounded the proposition that "heaven and man win", then explained that "qi wins, and strength wins", and put forward a view of nature with "qi" as the tradition of everything. He believes that "qi" is the basis of material existence, and explains the development and change of everything in time with the interaction of clear qi and turbid qi, yang qi and yin qi, pointing out that "his article is magnificent, clear in logic, detailed and vivid in examples, comprehensive and extraordinary in momentum.
He believes that literature should reflect the pursuit of the times, and the quality of articles is closely related to politics. Liu Jun, a native of the Tang Dynasty, wrote in Collection: "Eight tones are related to political communication, while articles contend with the times. Three generations of writings, fell ill during the Warring States Period, and revived during the Qin and Han Dynasties. Many countries in the Han Dynasty fell ill and Tang Xing revived. The husband's government is torn by pang, and the three lights and five mountains are divided, and the big voices are endless, and they must be mixed and then shaken. " The general idea is that a chaotic political situation and a divided country will lead to the division of the three lights and five mountains, and the articles written at this time are fragmented and not smooth; Only under the unified dynasty can literary creation be smoother. Although this view is biased, it is also commendable. In the Collection of Gong Li in Ancient Guo Xiang in Tang Dynasty, he talked more directly about the relationship between discipline and handling affairs and politics. In Ji Ji, he pointed out that the article should be able to play the role of "the bystander is clear, standing on the cheek and tongue of the dynasty to blame the masses, and becoming a huge political shock in the palace". This shows that Liu Yuxi attaches importance to the practical function of the article.
He said in the History of Hengzhou Runjun County in the Tang Dynasty: "The past is a book, and words are spoken before things happen. Jia Sheng's book began with Guo Qin, and Gou Jian wrote it later. " The general idea is to emphasize "statement" first, and then "expressing things". As the main body of "expressing ambition" activities, the writer's personal characteristics are more important. "The Book of Shangdu Situ" said: "Han Fei is good at writing books, but" Difficult "and" Lonely Anger "are especially good. Therefore, Sima Zi was deeply saddened by it, and showed what the text wanted. The book Husband Right and Wrong can be described as a love story, which makes everyone who meets you sit up and take notice, no different from other books. And those who are deeply sad are not influenced by the secular world. Do you think their words are evil? " By enumerating Sima Qian's special feelings for Han Feizi's articles, this paper emphasizes the unique influence of the writer's own experience and emotional experience on literary creation and experience.
The status of Liu Yuxi's articles is also reflected in the influence on later generations. For example, Tian Wen in philosophy had a far-reaching influence on Zhang Zai's materialism. On the basis of Liu Yuxi, he demonstrated that "too empty qi" is the only ontology of "harmony between man and nature" His tradition of academic innovation also influenced Wang Anshi's political reform, which enabled Wang Anshi to find an ideological weapon conducive to political reform and innovation-materialist atheism.
Even though Liu Yuxi's articles are not as well-known and widely circulated as his poems, they still occupy an important position in the literary history of Tang and Song Dynasties, which has had a great influence at that time and later generations, and the great personality pinned on the articles is still immortal.
