What is the change of Yuanjia's poetic style?

The change of Yuan Jia's poetic style is to replace Hyunri with emotion and return to emotion from philosophical thinking. Most poets in the Eastern Jin Dynasty changed the style of metaphysical poetry, paying attention to describing landscapes and duality, and formed a trend of rhetoric and confrontation. Yuan Jia's poems, which began in the first year of Yi Xi and ended in the second year of Taishi, have been circulating in the poetry circle for more than 60 years and are divided into two periods with the decade of Yuan Jia as the boundary. Under the same value orientation of * * *, two different artistic pursuits appeared in the two periods. The two schools of "color" and "rhyme" finally merged well into Yongming's poems, which emphasized the artistic form. In artistic expression, it also changed from bland to bland, and paid attention to the discussion of artistic forms and techniques of poetry. Reason: During the Liu and Song Dynasties, metaphysics did not occupy a major position in the ideological field, while Confucianism occupied the mainstream in the political field.
