Who are the three literary masters in the Northern Song Dynasty? Their achievements and influence in the history of literature?

There were many writers in the Northern Song Dynasty. Now, take Ouyang Xiu, Su Shi and Wang Anshi as examples. Ouyang Xiu: Ouyang Xiu has the highest achievement in literary creation. When commenting on his essays, Su Shi said: "On Taoism, it is like Han Yu; In books, it is like Lu Zhi; In the chronicle, it seems like Sima Qian; In poetry and prose, it is very similar to Li Bai. " Ouyang Xiu wrote more than 500 essays in his life, each with its own characteristics, including political essays, historical essays, notes, lyric essays and notes. Most of his essays are rich in content, vigorous in momentum, simple in explanation, concise and fluent, narrative and reasoning, beautifully expressed, lyrical in description, fascinating, plain and strange, and new in literature. Ouyang Xiu was also a pioneer in the creation of notes in Song Dynasty. Ouyang Xiu also made great achievements in poetry creation. Ouyang Xiu plays an important role in the history of China literature. He vigorously advocated the poetry innovation movement, reformed the formalism style of writing and poetry from the late Tang Dynasty to the early Song Dynasty, and achieved remarkable results. Su Shi: Su Shi's literary view is in the same strain as Ouyang Xiu's, but he emphasizes the originality, expressive force and artistic value of literature. His literary thoughts emphasize "doing something and not doing something", advocating nature, getting rid of bondage, and "innovating statutes and releasing wonderful ideas". There are about 4,000 existing Su poems, which have a wide range of contents and diverse styles, but they are mainly bold and unconstrained, with changeable brushwork and romantic color, which has opened up a new road for the development of Song poetry. There are more than 340 poems written by Su Shi, which break through the narrow theme of writing about love and parting between men and women and have a wide range of social contents. Su Shi occupies a special position in the history of China Ci. He extended the spirit of the poetic innovation movement in the Northern Song Dynasty to the field of Ci, swept away the traditional style of Ci since the late Tang Dynasty and the Five Dynasties, and created an unconstrained Ci school that kept pace with the graceful school, expanded the theme of Ci, enriched the artistic conception of Ci, broke through the boundary between poetry and poetry, and made great contributions to the innovative development of Ci. Wang Anshi: Wang Anshi was one of the "Eight Masters" in Tang and Song Dynasties. His prose is vigorous and concise, mostly in the form of books, tables, notes and preface, expounding political opinions and opinions and serving reform and innovation. These articles have clear views and profound analysis on current political or social issues. Long articles are horizontal but not concise, short ones are broken but not detailed. Wang Anshi's poems can be roughly divided into early and late periods, with obvious differences in content and style. The early poems are good at reasoning and have obvious tendencies, involving many important and sharp societies. The problem noticed the sufferings of the lower classes and made an unfair voice for them. Wang Anshi's seclusion in his later period brought about changes in his poetry creation. He lingered and reveled in the countryside, with a narrow theme, and a large number of poems about scenery and things replaced the previous political poems, expressing a leisurely interest. However, the artistic expression technique is sophisticated, the observation is meticulous, exquisite and beautiful, the artistic conception is distant and fresh, and it shows the praise and love for the beauty of nature, which has always been told by people. From the literary point of view, Wang Anshi's works have made outstanding achievements in poetry, prose and ci. The poetry innovation movement in the mid-Northern Song Dynasty was vigorously promoted by him, which contributed to sweeping away the glitz and splendor that was all the rage in the early Song Dynasty.
