The Chinese poems "Autumn Night in Rain" and "Jiangnan Women" are quite skillful in the prosperous and late Tang Dynasty. After returning to China, he wrote poems such as Yuxing, Guyi, and Shu Sunflower, which reflected the darkness of troubled times and social evils. He was recognized as the founder of Chinese literature by Korean dynasties and contributed to the cultural exchange between China and North Korea. China's "The Book of the New Tang Dynasty, the Records of Art and Literature" has its own biography, and his works are collected in The Complete Poems of Tang Dynasty, The Collection of 1 Famous Scholars in Tang and Song Dynasties and The Collection of Fifty Small People in Tang Dynasty published by China in the late Qing Dynasty. He is the originator of Korean Chinese literature. I have learned and accepted a lot of China literature during my 17 years in China. Cui Zhiyuan was influenced by seven-character poems and seven-character quatrains in the late Tang Dynasty, and most of his poems were seven-character poems and seven-character quatrains. Stylistically, he was exposed to a cool, sad and melancholy romantic atmosphere. He has made great contributions to enriching Korean literature.
