Starting from the Liang Dynasty of the Southern Dynasties, the palace became the center of poetry creation, and this situation continued until the early Tang Dynasty. The style of court poetry during the Zhenguan period has undergone great changes compared with the previous generation. First, the artistic conception of poetry has expanded, showing a general interest in "big" things; secondly, the poetry reflects the strong personality that is lacking in the court poetry of the Southern Dynasties; thirdly, , many ministers began to consciously use poetry to intervene in politics. These changes had a positive impact on later poetry creation.
