According to No.68 of the Biography of Huang Yaochuan in the Yuan Dynasty, "Guan, the word ... together with Mei Ao and yu zhang, revealed the truth, and the person number was' Four Gentlemen'."
In the fourth year of Yuan Dade (1300), Chaju was an edict of Jiangshan County, and a few years later it was promoted to Zheng Xue, Changguo Prefecture. In Yan 6 (13 19), he worked as a teaching assistant in Guo Zi, and was promoted to be a doctor. He became an official when he was good at learning, and became an official after his official career. Among them, Song Lian, Wang and Dai Liang are the most famous.
In the first year of Taiding (1324), he was promoted to Dr. Taichang. All court ceremonies must be based on ancient and modern times, and everyone must accept its careful examination. Taiding was promoted to Confucianism in Jiangxi for three years (1326), and returned to Doumen for less than ten years, where he was apprenticed, studied and immersed in Neo-Confucianism.
In the first year of Zheng Zheng (134 1), the imperial court reused him as an official of imperial academy and editor of the National History Museum. In the second year (1342), 1 1, Zheng Zheng died in the capital (now Beijing).
Liu Guan's official position is limited to five grades, and his salary does not exceed one thousand stones. But it had a great influence on the literary world at that time. His poems are ancient and difficult, meaningful and widely respected. Some people call him "a handsome man in the literary world, a literary hero".
Song Lian, the "leader of the founding civil servants" in Ming Dynasty, was Liu Guan's most proud disciple. Song Lian once described Liu Guan's knowledge and his relationship with his teachers as follows: "(Liu Guan) read widely and memorized books by rote. He dabbled in rites and music, military punishment, Yin and Yang, legal calendar, nature, geography, philology, genealogy and old Buddhist books ... Although he was not sensitive, he was taught by teachers.
Liu Guan's famous books include Epigraphy 10, Jin Guang Ji 3, Zi Si 2, Liu Ji, Zhi Dai Ji, Zi Si Ji 20, Jin Guang Ji and Jin Boyi Ji.
Liu Guan's poetry is ancient, hard, strange and meaningful, which can be represented by the poem Mountain Bridge. He himself said, "Poetry is placed in Jiangxi society, and Tuyuan Liangyuan is separated by several springs." It can be seen that he worships Jiangxi Poetry School. In the self-titled manuscript, he said: "He Yong exaggerated the danger, but I really hate magic." I'm a little dissatisfied with Jiangxi Poetry School. He has several poems describing the life of the salt people on the seashore, such as "My First Birth Today" ("My Topic") and "Bloody Whip" ("The Feeling of Spending the Night in a Long Reed Book"), which show sympathy for the people in distress.
Liu Guan's literary title is greater than that of poetry, and his prose is vigorous and rigorous, good at discussion, detailed and verbose, which can be said at that time. However, most of his essays are applied words such as epitaph, promoting learning and building bridges, and rarely show his temperament. There are only a few articles, such as Answering Wei Taipu's Calligraphy in Linchuan, with clear words and sincerity. Commenting on the social atmosphere at that time, he said: "Compared with decades, scholars are generally self-interested, but their ambitions are getting lower and lower, and their Tao is getting farther and farther." Referring to the literary world at that time, he said: "The marginal ornaments are shallow enough to brag about the forest of production and hunt for the wealth of celebrities." These words hit the nail on the head. Liu Guan also has some inscriptions, which are brief and natural. Compared with inscriptions, they are lively and can be regarded as some good essays.
