In the early Tang Dynasty for decades, the whole poetry world was permeated with Qi Liang and Yu Feng, and the content and style of poetry failed to get rid of the shackles of the palace style of the Six Dynasties. At that time, the "four masters in the early Tang Dynasty" and others made breakthroughs and innovations in their works, revealing a different charm from the poems of Qi Liang Palace. However, on the one hand, due to the initiative of the ruling class, the legacy of Qi and Liang Dynasties had a deep and wide influence, and the premature death of the four great masters failed to become a common practice, and the situation could not be completely opened.
Chen Ziang, a famous poet in the early Tang Dynasty, strongly advocated that poetry should reflect reality and opposed the flashy atmosphere of formalism since Qi and Liang Dynasties. He was the first poet in the early Tang Dynasty who consciously took it as his responsibility to restore the "Han and Wei style". His poems restored the fine tradition from the Book of Songs to the Han and Wei Dynasties in content and form, inherited and carried forward realism and positive romanticism, and abandoned the frivolous and flashy style of Qi Liang's poems. He contributed to the prosperity of poetry in the prosperous Tang Dynasty. The influence of his literary thought and creation played an important role in creating a new poetic road in the Tang Dynasty.
Du Fu and Han Yu respect him very much. Bai Juyi compared him with Du Fu and said, "Du Fu and Chen Ziang are world-famous." His poems are full of passion, lofty style and "Han and Wei style", which is praised as "poetic bone" by later generations. It can be said that Chen Ziang's poetry creation is a watershed in the development of poetry circles from the early Tang Dynasty to the prosperous Tang Dynasty, which opened the prelude to the climax of poetry creation in the prosperous Tang Dynasty.
A kind of "hard and thin body" appeared in Song Dynasty, which refers to a style between Liu and Su. The main writers are Zhang Xian, Fan Zhongyan, Yan Shu and Ouyang Xiu. Most of them are elite literati in the middle and early Northern Song Dynasty, and they are not satisfied with the fragrance of Liu Ci. So they try to learn from the poetic style, turn vulgarity into elegance, condense long and short, and break the various patterns of popularization of Liu Ci. In this way, Su Ci, which was originally regarded as a bold and unconstrained nature, became a rootless tree and passive water, which was properly expounded by Zhang Xian, Yan Shu and Ouyang Xiu, and it was concluded that thin hardware was the forerunner of Su Shi's "taking poetry as a word".
