Yu Xin is "young, handsome and extremely intelligent". He went in and out of Xiaogang's court with his father since childhood. Later, together with Xu Ling, he became a representative writer of court literature, and his literary style was called "Yu Xuti". General You Wei, a tired official, was appointed as the county magistrate of Wu Kang. During the Hou Jing Rebellion, Yu Xin fled to Jiangling. Later, he was ordered to send envoys to the Western Wei Dynasty. Because Liang was destroyed by the Western Wei Dynasty, he stayed in the north, and the official was the general of the car and the general of the government. After the Northern Zhou and Wei Dynasties, it was transferred to the General of Standard Qi, the Division of Kaifu Yitong and the Division of Linqing County, which was called "Yu Kaifu" in the world. At that time, Chen made friends with the Northern Zhou Dynasty, stayed with others and promised to return home. Only Yu Xin and Wang Bao are not allowed to go back to the south. In the north, on the one hand, Yu Xin was honored as a master of literature, received the courtesy of the emperor, and made friends with kings. On the other hand, he deeply missed his hometown, was ashamed of being an enemy country, and resented that he was not free. Finally, in the first year of Wendi (58 1), he died of old age in the north at the age of 69. There is a collection of Yuzishan handed down from generation to generation, and Zhang Pu compiled a collection of Jade Kaifu in the Ming Dynasty.
Yu Xin is the most famous poet who goes from south to north. He suffered the bitter life peculiar to the split era, but he achieved the literary achievement of "the victory of the poor north and the south". His literary achievements also show the prospect of the integration of North and South styles.
Basic introduction of real name: Yu Xin's alias: Yu Lancheng, Yu Kaifu, Yu Yicheng's font size: Zi Zishan's year: Southern and Northern Dynasties (Liang Dynasty → Western Wei Dynasty → Northern Zhou Dynasty) Nationality: Han nationality's birth time: 5 13, death time: 58 1. Main works: Ode on the Dead Tree, Ode to the South of the Yangtze River, and Zhao Yun's ci. Major achievements: a literary master in the Southern and Northern Dynasties, one of the representatives of "Palace Poetry", a native of Xinye County, Nanyang County. Official position: rank of ancient general, title of the third division of Kaifu Yitong: posthumously presented by Hou of Yicheng County: life, early wisdom, courtesy, wandering from place to place, homesickness, major achievements, literature, politics, personal works, and character evaluation of the secretariat of Jing Huai State. Relatives, according to historical records, Yu Xin was born in the family of "seven generations of scholars" and "five generations of anthology", and was a descendant of Yu Yan, a writer in the Eastern Jin Dynasty. His grandfather, Yu Yi, should not have been drafted by the court when he was in Nanqi. His father, Yu Jianwu, used to be a constant attendant and secretary of Nanliang, and was a famous writer at that time. Yu Xin was smart since he was a child and read widely, especially the Spring and Autumn Annals. He is eight feet tall, with a waist of ten, and his appearance is slow and informal, which is different from ordinary people. In the first year of prosperous Datong (527), 15-year-old Yu Xin entered the palace to give lectures in the East Palace of Prince Xiao Tong until Xiao Tong died in Datong for three years (53 1). At this time, King Xiaogang of Jin 'an (Emperor Liang Jianwen) was made a prince, and Yu Xin's father, Yu Jianwu, was the illegitimate child of the prince, in charge of documents. Yu Xin, aged 19, also became a doctor in the East Palace. Father and son are in the East Palace, and their kindness and courtesy are unparalleled. He and Xu Ling are brilliant and gorgeous in writing, and are called "Yu Xuti" by the world. Scholars at that time and later scrambled to imitate his articles. Every article they wrote was read by the capital. Later, Yu Xin became the attendant of Xiao Yi, the king of eastern Hunan, and was transferred to Annan House to join the army. Later, after many promotions, Yu Xin became a doctor and a member of Shangshu. In the eighth year of Datong (542), Yu Xin became a bus driver in Yunzhou. In the 11th year of Datong (545), Yu Xin served as a regular servant in the Eastern Wei Dynasty. His articles and speeches were highly praised by the summer night. After returning to Korea, Yu trusted the Bachelor of Oriental Palace and served as the Health Order. In 548, the "Hou Jing Rebellion" broke out, and Hou Jing, commander-in-chief of the Eastern Wei Dynasty, led an army to revolt. Xiao Gang ordered Yu Xin to lead more than a thousand civil and military officials in the palace to camp in Suzaku Hangbei. When Hou Jing arrived, Yu Xin quickly led the army to withdraw. After the fall of Taicheng, Yu Xin went west along the river and fled to Jiangling, where he was appointed as an imperial minister by Xiao Yi, the king of eastern Hunan (Emperor Liang Yuan). In November, 552, after Xiao Yi ascended the throne, Yu Xin was transferred to the position of right general, and was made the marquis of Wu Kang county, and at the same time, he was also made a constant servant. In April (554), Yu Xin was ordered to be sent to the Western Wei Dynasty. Shortly after arriving in Chang 'an, the Western Wei Dynasty conquered Jiangling and killed Xiao Yi, so Yu Xin stayed in Chang 'an, and was appointed by the Western Wei Dynasty as General Jie Jie, Fu Jun, Doctor You Jin Guanglu and viceroy, and was later promoted to General Che Qi and General Yitong. After Emperor Yuwen of the Northern Zhou Dynasty ascended the throne, Yuxin was named Linqing County, with 500 restaurants and served as an underwater doctor. He became the chief of Hongnong County, and was promoted to the title of generals in ancient times, the Third Division of Kaifu Unification, Sixian Chinese Medicine, and the Hou of Yicheng County. Soon after, he was appointed as the Los Angeles Secretariat. Yu Xin is familiar with many laws and regulations in the old society, and his administration is simple and quiet, and the government and the people are at peace. Yu praised: "Only those who hide curtains dare to stab, officials dare not take bribes, and the people can't bear to be bullied. Go to Luotong, such as welcoming Ji Guo; Being good and old seems to be worth ricas. " At that time, the Chen Dynasty made friends with the Northern Zhou Dynasty, and both the North and South people who had lived in other places were allowed to return to their hometown. Chen demanded the release of more than ten people, including Bao Wang and Yu Xin, while the Zhou Emperor Yu Wenyong only released Yin Buhai and kept Yu Xin and Bao Wang. Soon after, Yu Xin was recruited as a Chinese medicine practitioner. Both Zhou Emperor Yu Wenyu and Wu Di Yu Yongyong loved literature, so they were very fond of Yu Xin. As for Wang Zhao Yuwen Zhao and Wang Teng Yu Wenji, they have sincere contacts with Yu Xin, just like the friendship between clothes. Most of the tombstones and epitaphs of the Northern Zhou Dynasty were written by Yu Xin. At that time, only Wang Baohe Yu Xin was an equal, and the rest of the literati were incomparable. Miss Home Although Yu Xin is a powerful person, he often misses home, so he wrote "Mourning for Jiangnan" to express his feelings of missing. In the early years of Emperor Jing of Zhou (579-580), Yu Xin left his job due to illness. In the first year of Kaiyuan (58 1), Yu Xin died at the age of 69. Deeply saddened, Emperor Wendi of the Sui Dynasty gave him his post, and he was also given the title of Jing Huai's secretariat ("History of the North" as Yong), and his son was given a hereditary title. Yu Xin's literary creation is the main achievement of literature, which can be divided into two periods with his 42-year-old mission to the Western Wei Dynasty as the boundary. In the early period of Liang Dynasty, most of his works were palace-style, light and elegant, and full of beauty of words. After the Northern Dynasties' imprisonment, poetry and Fu both expressed a lot of homesickness and sadness about life experience, and their styles also changed into vigorous sadness. Yu Xin lived in the Southern Dynasties in his early years, which happened to be the most stable stage of the establishment of the Liang Dynasty. In his "Mourning for Jiangnan", he described it as "nothing happened in the river for fifty years". His early poems were for the amusement of kings, and his thoughts were frivolous. His works in the Liang Dynasty, especially his poems and poems during his tenure in the East Palace from 65438 to 36, were mainly based on harmony and adaptation, and their themes basically exceeded the categories of flowers and birds, beautiful women, singing and dancing, boudoir and so on. For example, Dancing in Harmony, Offering Harmony in Early Autumn and Ode to Yuanyang all belong to the same topic written by scholars around Xiao Gang. This kind of creative activity full of entertainment atmosphere requires the author not only to adapt to the interest of the court, but also to show his personal education and literary talent in social interaction. Yu Xin's "young and handsome, intelligent and peerless", coupled with his "extensive reading, especially Zuo's Biography in the Spring and Autumn Period", made him quickly gain the same reputation as Xu Ling. However, as a courtier of court literature, it is not easy to express personal beliefs or feelings. For example, Yu Xin has a poem "The Wind and the Floating Picture of Tongtai Temple", which is sung together with Xiao Gang's "The Floating Picture of Wangtongtai Temple". The devotion to Buddhism expressed in the poem actually focuses on the mood of the Crown Prince, and it is impossible to simply conclude that Yu Xin believes in Buddhism. This situation also applies to other literary attendants in the East Palace. Because Xiao Gang and others were in charge of new changes, they influenced the creation at that time, broke the stereotypes and opened the way for the development of Tang poetry. Yu Xin's early works have made great contributions in this respect, such as the seven words and eight sentences in "Night Cry", which are sonorous in tone and basically conform to the level tone of rhythmic poetry. Another example is Ge Yanxing, which expands the system of seven-character ancient poems, not only lengthens the narrative space, but also changes the rhyme between sentences to rhyme according to the ups and downs of feelings. His early exploration of poetic forms is worth cherishing, and both Yang Shen in Ming Dynasty and Liu Xizai in Qing Dynasty recognized his role in it. Yu Xin's accumulated literary experience in the Liang Dynasty includes not only the management of aesthetic forms, but also the understanding of aesthetic contents. Xiao Yi said: "Chanting wind ballads, lingering is the text." Yu Xin had a sentimental aesthetic interest in his early days, and expressed his sadness with colorful words. Yu Xin's later life experience fully realized this aesthetic pursuit, thus reaching an artistic realm higher than that of his contemporaries. Later, because of the Hou Jing Rebellion, the Liang Dynasty was on the verge of collapse. Emperor Liang Yuan tried to revive in Jiangling, but soon died in the Western Wei Dynasty. Yu Xin was sent to Chang 'an as an envoy, but due to the fall of Jiangling, he could not return to the south. He worked in the Western Wei Dynasty and the Northern Zhou Dynasty, and served as a general in title of generals in ancient times and an official in charge of the court. According to Zhou Shu's biography, he "often wants to go to the countryside, although he is looking forward to it." His homesickness is a sad speech, which contains rich ideological content and deep feelings. His style is desolate and his art is more mature. Du Fu said in "The Play is Six Poems": "Yu Xin's articles are old and familiar, and his brushwork is vertical and horizontal"; He also commented on his "land where poetry stirred up the river in his later years" in "Bei Fu", which refers to this feature of his later works. Chu Suiliang's description of Yu Xin's "Ode to a Dead Tree" (running script) is sentimental, time has changed, and his soul leads the motherland, which is an important aspect of his "homesickness". Yu Xin was shocked by the changes in the country. "It has been a place for song and dance performances since ancient times, but today there is no place to go." This sense of vicissitudes made him more deeply realize that between personal destiny and national destiny, it is like "a running horse, without a hair moving;" A boat is covered, and it is all heavy. " Therefore, while expressing his personal pain of national subjugation, he can also reflect the people's sufferings with compassionate brushstrokes, and blame it on the infighting and idleness of those in power. Yu Xin, who has lived in the north for a long time, is eager to return to the south and look forward to the mountains and rivers of his old country. When I saw the Weihe River, I saw the scenery in the south of the Yangtze River: "The trees are like the new pavilion bank and the sand is like Weilong Bay. If you say anything else, put down the sail. " Suddenly seeing betel nuts will also evoke homesickness: "The green house is ripe and the purple ears are blooming. Don't talk about Wan Li, I have seen him once. " On the way to see Wang Lin off, Yu Xin couldn't help feeling sad after receiving a letter from an old friend in the south. The General Catalogue of Sikuquanshu praised Yu Xin's works after moving northward as "rich in content, full of emotion and literariness, full of yellow dialogue, relaxed in spirit and free to change". From the poem Send Wang Lin, we can see the author's superb art. Sighing and hating about travel and worrying about life experience are another important aspect of his "homesickness thinking". Although he got "high officials and beautiful officials, and some of them even surpassed the old country" after moving to the north, he felt that he was tantamount to "advocating that his family was forced to hire, and the proton value still existed", and blamed his detention on "forgetting Chu and Cao, but eating Zhou Wei". His aversion to travel is intertwined with his anxiety about life. He used the image of "thinking when the water is dry, and being surprised when the forest is exhausted" to illustrate the powerlessness of personal survival. Yu Xin claimed that the poem Mourning for the South of the Yangtze River, written in his later years, was "not without danger and suffering, but mainly based on sadness". Ni Kun commented on this topic: "After Zi Shan entered the customs, the article was more sad and resentful, and he was not alone." It is the spiritual feature of Yu Xin's later literature. His "Twenty-seven Poems of Singing Huai" expresses sorrow from many angles with the system of five-character poems, which directly inherits the lyric tradition of Ruan Ji's "Poems of Singing Huai", especially outstanding. For example, in No.7 Middle School, I borrowed a woman who lived in Alakazam and missed the Han Dynasty, and compared her hidden hatred for being an official in the north with her desire for the return of the south, which was sincere and touching. Another example is the concern expressed by the 18th National Congress of the Communist Party of China, which is not only the frustration of not achieving official career, but also the grief of not establishing great honor for the country, so there is no room for self-deprecation or detachment. In this poem, the four sentences of "waning moon" describe the scenery, and the sentence patterns are ingenious and clumsy, which can project the poet's unique state of mind and show the poet's meticulous brushwork. The experience from south to north made Yu Xin's artistic attainments reach the height of "the victory of poor north and south", which is of typical significance in the history of China literature. Yu Xin learned from the rhythm and antithesis of Qi and Liang literature, accepted the vigorous style of northern literature, developed and enriched the aesthetic mood, and made necessary preparations for the formation of the new poetic style in Tang Dynasty. When Yu Xin served as the secretariat of Luozhou in the Northern Zhou Dynasty, his administration was short and quiet, which made the officials and people get peace and made great achievements. In Preface to Yu Xin Ji, the word Wendi compares his popularity with Ji Guo, a famous minister in the Eastern Han Dynasty, and Likas, a famous minister in the Western Jin Dynasty. Yu Xin's personal work "Yu Kai Fu Ji" has been handed down from generation to generation, and Ni Kun of A Qing Dynasty made an annotation and renamed it "Yuzishan Ji". In this version of Yuzishan collection, the four-series photocopying of the Ming Dynasty Dragon Slayer was the earliest. Wang Ben 12 is recorded in the Notes to the Concise Catalogue of the Four Supplements; There is also a printed version of Zhu, which is only six volumes, with poems and no texts. In addition, there is Zhang Pu's 103 Books Collected in the Han, Wei and Six Dynasties, which is called Yu Kai Fu Ji. In the Qing Dynasty, Yan Kejun recorded eleven volumes (Volume 8~ Volume 18) of his works in The History of Ancient Three Dynasties, Three Kingdoms, Qin and Han Dynasties, Six Dynasties and Later Zhou Wen. Qi included his own poems in three volumes (2~ 4 volumes) in the Poems of the Northern Zhou Dynasty before Qin, Han, Wei, Jin, Southern and Northern Dynasties. Yu Xin is a figure in the history of China literature. No one can compare with Bao Zhao in the Northern Dynasties. At that time, there was a saying of "Yu Xu style". At that time, Xu Ling tied with it, but in fact, Xu Ling's performance was below it. Yu Xin is one of the prolific writers in the history of China literature, and he has made great achievements in poetry and prose. His poems and Fu also occupy an important position in the history of China Fu. It is different from the Sao Fu of predecessors and the law Fu of later generations. In the Han Dynasty, he turned prose into parallel prose, which made Fu more formal and developed to a new stage. At the same time, Yu Xin also advocated the Tang people to write poems into Fu, which influenced the parallel prose of He Luo in the Tang Dynasty. Parallel prose flourished in the Six Dynasties, and Yu Xin was a master. Yu Xin is the most famous poet who goes from south to north. He suffered the bitter life peculiar to the split era, but he achieved the literary achievement of "the poor north and the south win". His literary achievements show the prospect of the integration of North and South styles. Yuwen Hu has commented in the past dynasties that the people in southern Yuwen Hu are filial to nature, in mourning and almost extinct. When I see them, I can't bear to look at them. Wang Tong: Xu Ling and Yu Xin, who boasted in ancient times, celebrated their birthdays. Li yanshou: (1) Since Datong, Liang has been lacking in refined morality, and has gradually followed the rules, striving for novelty and originality. Wen Jian (Xiao Gang) and Xiang Dong (Xiao Yi) started their lewdness, while Xu Ling and Yu Xin parted ways. Its meaning is shallow and complicated, its text is hidden and colorful, its words are light and dangerous, and its feelings are full and sad. Listen to Yanling, and cover the voice of national subjugation. (2) Wang Bao, Yu Xin, Yan Zhitui, Yu Shiqi, Liu Gui, Xu, Ming Kerang, Liu Zhen, Yu Chu, etc. And they are very famous in the south, famous for their talent, and expensive is also appropriate. Linghu Defen: Erqi Well and Hengqizi, in the middle and southeast of bamboo arrows, are temples. Only Wang Baohe Yu Xin is a wizard, and a generation is locked in a cage. At that time, Sejong Yazi Yunwei, Teng and Zhao Erwang carved chapters. Building an empty palace with salt is like the friendship of cloth and clothes. Because he is from the imperial court and the state of Yan, he never forgets to taste the charm and show off the last light. Still in the mountains, with Dai, and in the rivers, Zongbo also. But Zishan's articles originated in the late Song Dynasty and prevailed in Liang Dynasty. His body is obscene, and his words are light. Therefore, I can praise my eyes and heart better than Zheng and Wei ... If I stand on the other side, I am a sinner of words. Zhang said: Lan Cheng chased Song Yu, a puppet poet in my old house. The pen rushes to the mountains and rivers, and the text is arrogant. Du Fu: ① Qing Xin Yu opened the government, and Jun Yibao joined the army. ② Yu Xin's articles are older and more mature, and Ling's brushwork is vertical and horizontal. Yu Xin's life is the most miserable, and his poems in his later years caused a sensation in the north and south of the country. Huang Tingjian: Xie's Yicheng poems have made great contributions to the work of the furnace hammer. However, the walls of Taopengze are few and far between, but Xie Yu failed to peep at them. Gail's intention is to praise the vulgar for ruining their works and send them a profound message. Yang Shen: Yu Xin's poem, Liang Zhiguan, was driven before the Tang Dynasty. Xia Wanchun: The Su (Su Wu) Festival is over, and Yu Kaifu's generals have been abandoned forever. Wang Fuzhi: Since the Song and Qi Dynasties, the style of articles has been extremely rampant. People know that its obscenity is abhorrent, but they don't know that its falsehood is especially abhorrent. Southerners admire it and northerners make peace with it, so Wei Shou and Xing Zicai are like Xu Heyu. Hanging the shadow of an article and serving its heart harmoniously is considered to be beautiful, light and false. People are used to imitating each other, and there is no need to say what they want, so they can tell each other what they want. Its chastity is also not chastity; Its lewdness is not lewd; And my heart is long gone. Ji Yun: Yu Xin's Parallel Prose is a masterpiece of the Six Dynasties, guiding the way for the Four Masters and standing tall among the Four Six Masters since ancient times. Liu Xizai: The prosperity of Yuzishan started in the early Tang Dynasty with seven ancient times, and Wu Ye started in the Tang Dynasty with seven laws. Other styles were based on the five odd and five behaviors of the Tang Dynasty, which was particularly invincible. Lin Shu: Zi Shan's "Jiangnan Fu" is not named Fu, but should be regarded as the blood and tears of the doctor who died in the country. Liu: Yu Zishan and other sad and beautiful prose use allusions the most ... Their emotions and prose can be traced back to swimming, although they are very long and have no traces of accumulation ... So we know that piling is different from allusions, and I can assimilate them, but piling is blocked by them, but it is sluggish and ineffective. Qian Jibo: Carving and painting strange characters, fighting every day; And those who can do it, don't be angry, do it with the wind, colorful and elegant, but Yu Xin and Xu Ling are also ... but their talents are rich and beautiful, and they have been influenced by youth for hundreds of years in the Southern Dynasties. And it flows into the week, with a sense of wandering, transferred to the sound of health in the north, so the works after middle age can fade away from the splendor of the palace, but they are particularly desolate. Coloring with things, being good at laying out stories, touching chapters, feeling the rise and fall, fading scenery, and speaking Tsinghua; It is good at carving insects to make words. Things that are well used, according to the principle of ancient love and present, belong to rhetoric, which comes out with depression and frustration, so they pile up into smoke. Rich in talent, natural and healthy, with low bone grafting, Qi is a male. With majestic demeanor and full of vibration, Li Dian's new sound will not hurt the accumulation. I have tasted Han Yu's ancient prose, and I saw it in the mud; The parallel prose of the letter is sparse in the overall beauty. Han Yuxiong was not happy, but his letters were dense and sparse, beautifully organized, and his pen was used in the wrong place. Forty-six paintings in Tang and Song Dynasties were created on the basis of Mohan and Han and Wei Ci Fu, and their fulcrum was actually controlled by trust. Qian Zhongshu: Zi Shan's Ci is a work with vivid images and beautiful feelings. Such as Spring Fu, Qixi Fu, Lantern Fu, Duzhu Fu, Mirror Fu and Yuanyang Fu were all written in the Southern Dynasties. Her husband's attitude towards Wei and Zhou has changed a lot, but the two books "Elephant Play" and "Shooting Horses" are still the same. His poems, such as "Zhang", "Zhang", "Dead Tree" and "Sorrow", are all lyrical and profound, and they are all bypassed by Qu Zi, which is not a direct reference to the legacy, but the poor Jiangnan state of things is full of glory in sorrow. Do more work in the early stage, be lucky in the later stage, be muddy in the bright and beautiful, and be in the beautiful middle stream; If you work after you are poor, you will be more successful when you are old, but you will not be empty. * * * once said that Jiang Yan was far more than a writer in the Northern and Southern Dynasties, and Yu Xin was one of them. Anecdotes and allusions are amazing in literary talent. According to "Inside and Outside the Court", when Yu Xin went to the north from the early Southern Dynasties, most northern scholars looked down on him, and Yu Xin showed them his work "Ode to the Dead Tree". From then on, no one dared to treat euphoria lightly. The Joy of Browsing Sleeves Both Yu Xin and Xiao Shao, the imperial clan of Liang Dynasty, had the pleasure of Browsing Sleeves. When Xiao Shao was a child, Yu Xin provided him with food and clothing. Whenever a guest visits, Xiao Shao will also send wine to Yu Xin. Later, Xiao Shao became the secretariat of Yunzhou because of his attachment to Xiao Yi, the king of eastern Hunan (Emperor Liang Yuan). At that time, Yu Xin met with chaos in Hou Jing, and fled from Jiankang to Jiangling, passing through Jiangxia, but Xiao Shao was quite cold to him. At the invitation-only banquet, Xiao Shao sat under a green curtain and led Yu Xin into the banquet, leaving him sitting on another couch, showing his conceit. Yu Xin couldn't bear it. She climbed onto Xiao Shao's sofa drunk, stepped on the food, looked straight at his face and said slowly, "You look very different today." At that time, the banquet was full of guests, and Xiao Shao felt embarrassed. Ji Yun also mentioned the relationship between Yu Xin and Xiao Shao in Yuewei Caotang Notes: "If you are a child molester, you are not a woman. You hold a pillow, but you pay attention to color. When it is full of powder and fragrance, it is full of charming hope, it is full of flowers, it is not as affectionate as Jasper, but it is hugged as soon as it turns around; It has always been that the rich have run out of money, the nobles have moved their power, or their arms have been broken, or they have turned against each other. Xiao Shao is in Yuxin, and Mu Rongchong is in Fu Jian. It is recorded in history books, especially the author.
