Whose poetry creation in the early Tang Dynasty showed obvious retro tendencies?

Chen Ziang.

In the early Tang Dynasty, Chen Ziang's poetry creation showed an obvious retro tendency. He advocated the restoration of the elegant tradition of ancient poems comparing their emotions and expressing their aspirations, so that the poems would present a completely different spiritual style from the pavilion style that was popular in the court at that time. Chen Ziang liked the poetry creation methods in the Book of Songs very much, and he also advocated the Jian'an style and believed that emotions should be written out, not just described. Chen Ziang's poetry creation clearly and powerfully embodies the idea of ??innovation.
