A brief answer to Chen Ziang's poetics? And the characteristics of Xie Tiao's landscape poems?

Chen Ziang's poetics: Inheriting the style of Han and Wei Dynasties, criticizing the formalistic style of writing since Qi and Liang Dynasties, and putting forward the idea of adding temperament to style in an attempt to create a new system with both style and temperament, which is the content of Chen Ziang's poetics.

Xie Tiao consciously used the "four tones" to create poems, which further developed the poetic form from gorgeous and elegant architectural beauty to musical beauty with clever rhyme. His landscape poems also used the joy of landscape to dispel the dissatisfaction with the hubbub and political abuse, and even had the idea of "chatting and enjoying the scenery", but there was no decadent sigh. What he showed in his poems was the joy of "prospering Cangzhou", which not only completely cut off the tail of talking about Xuan, but also greatly reduced the tedious words and phrases, forming a fresh and beautiful style.
