In the era of literary prose, poetics got rid of the shackles of Confucian classics and began to explore the characteristics and laws of poetry itself, forming aesthetic thoughts that attach importance to images, styles, verve and diction. In the practice of poetry creation, the pursuit of "love" and "beauty" has also been formed. Therefore, Lu Ji's theory that poetry is beautiful with emotion is an artistic summary of the poetic style of the Jin Dynasty.
The prose emphasizes the creation of formal beauty, attaches importance to the pursuit of gorgeous rhetoric and double neatness, and even Lu Ji's other creations strive for this. However, the pursuit of gorgeous forms of poetry did not start from Lu Ji, nor did it stop there. From the early Jin Dynasty to Taikang, Fu Xuan, Zhang Hua, and other writers basically advocated this floating atmosphere. Zhong Rong's Shi Pin, Liu Yiqing's Shi Shuo Xin Yu, Pan Jinshu Yue Chuan and other classics have all commented that Zhang Hua's works are "gorgeous in literary talent and interesting. Clever use of words to serve Ye Yan "; Pan Yue's poems are "rotten as brocade", "rotten as brocade" and "flowery words". Commenting on the creations of generations such as Ying Zhen, Fu Xuan, Zhang Zai, Zhang Xie, Bird, Sun Chu, Zhi Yu, Cheng Gongshui, Liu Xie's Wen Xin Diao Long Time Series said: "The combination of algae and flowers is beautiful and charming." The admiration of these literati, especially Taikang's writing style, has a great influence on Luji. "Poetry" commented on Pan Yue's writing style as "graceful as a bird's feather?" Shallow than the land machine, the world is called "land and pan". Lu Ji's style has been seen. Lu Ji's theory of "poetic sentiment" shows that his literary creation pursues the perfection of form and the expression of subjective emotion, which requires poetry to have artistic characteristics of "sentiment" and "beauty". The book "Biography" says: "The machine is talented and elegant, and the words are magnificent." As can be seen from the previous comments, Lu Ji's writing tends to be "clever" and "elegant". Even the Yuefu poems he admired were praised as "the voice of the stone and the spirit of the storm" by Liu Xizai's Jian Yi Shi Jian, which can make readers soul-stirring. Although the son built Yuefu, he could not specialize in beauty. " From the above, Lu Ji, like most writers before and after the times, has a general trend of pursuing the beauty of poetry, which represents the trend of the times in the development of poetry. What is commendable is that Lu can undertake the historical responsibility of literary development, theoretically explore and summarize the literary practice since Jian 'an, break through the cage of Confucianism and put forward a brand-new theory of literary creation. In particular, he attaches importance to the emotional factors and artistic essence of literary works, especially poetry creation, clearly affirms the law of literary movement in which poetry has developed in the direction of lyricism and formal beauty since Jian 'an, and puts forward the view that "poetry is beautiful with emotion", which is an exploration and excavation of the artistic characteristics of poetry. Therefore, Lu Ji's theory that "poetry is beautiful because of emotion" is a new aesthetic thought of poetry based on grasping and summarizing the laws and trends of literary movement. The purpose of literary creation is to express this feeling caused by concrete things. Therefore, the whole creative process must, of course, take "predestination" as the purpose and take artistic beauty such as flowery words as the method. "Wen Fu" emphasizes that poetry creation should be "considerate, phrasing and sentence-making, iterative in sound and sound, if the five colors are harmonious" and "beautiful but beautiful", that is, poetry should be skillful and elegant in artistic form, beautiful and beautiful, and pay attention to sound and sound beauty. This is a theoretical reflection of the new changes in poetry creation since Wei and Jin Dynasties. Lu Ji requires the use of literary ideas in his creation, the use of words in his conception, the mobilization of artistic methods and aesthetic skills, and the full expression of the author's artistic feelings and emotions, so as to achieve the artistic realm of "caging heaven and earth in shape and frustrating everything in pen", so as to have substance in words and enlightenment in writing; It also emphasizes attaching importance to sound and pursuing the beauty of rhythm in literary works. Lu Ji's theory about the importance of rhythm to literary creation was discussed for the first time in the history of China's ancient literary theory, which became the origin of the temperament theory advocated by Ye Fan and Shen Yue in the Southern Dynasties. However, Lu Ji also clearly pointed out that the meaning and wording of the article must be organically combined and harmoniously unified in order to receive the expected results. Words are insincere, insincere, insincere, and insincere. If you can't organically combine "destiny takes a hand's love" with "extravagance", there will be "love that is light and fresh, but floating without returning; The situation of "harmony without sadness" has lost the artistic beauty and social function of literary works. Combining with his own creative activities, Lu Ji summed up the literary spirit of the new era, put forward the artistic viewpoint of "poetry is beautiful because of emotion", formed the poetic theory of "paying equal attention to emotion and quality" in the history of later literary criticism, further revealed the essential attributes of poetry, realized the unity of ideological content and artistic form, and produced a positive influence and function that cannot be underestimated. At the same time, Lu Ji directly promoted the literary creation activities in the Southern Dynasties through his own theoretical advocacy and artistic practice, and prepared for the improvement of China's classical poetry and the prosperity of Tang Dynasty's poetry creation.
