In the famous Preface to the Pearl Show, Chen Ziang once put forward a positive proposition of poetry innovation: Oriental style comes first; the article is flawed, which has been in the Han and Wei dynasties for 500 years, but the literature is worth textual research. In his spare time, the servant tasted the poems between Qi and Liang, full of colorful and complicated poems, but he was absolutely willing to send them. Every time I sigh through the ages, I often fear decadence and elegance when I think about the past. Yesterday, I saw the "Three Lonely Tung Fu", which is full of vigor and vitality, full of sound and emotion, brilliant, and trained in gold. Then decorate your vision with your heart and play the melancholy down. I don't want to start the sound, but I will see it again; Can make Jian' an authors smile at each other. ..... In the history of the development of Tang poetry, Chen Ziang's essays are like a declaration, marking the innovation and transformation of the poetic style in the Tang Dynasty. As we know, Liu Xie and Zhong Rong opposed the poetic style of formalism in the Southern Dynasties and once held high the tradition of "comparison" and "character". Wang Bo opposed the style of court poetry before and after The Dragon, and accused them of being "spineless and lifeless". Chen Ziang inherited their thoughts, pointedly pointed out that the poetic style of Qi Liang worshipped by the court poets in the early Tang Dynasty was "colorful but not vulgar", and pointed out that the glorious traditions of "elegance and vulgarity" and "Han Wei style" were pioneer examples of creation, which realized the real innovation of poetry content under the banner of advocating retro. The attitude is very firm, the flag is very clear, and the call is very strong. "Ji Xing" and "Feng Gu" are the primary issues related to the life of poetry. The essence of "good luck" is to require poetry to carry forward the tradition of criticizing reality and has a distinct political tendency. The essence of "style" requires poetry to have noble and rich thoughts and feelings and rich and substantial realistic content. Judging from the situation at that time, only by realizing the real innovation of content can poetry undertake the mission of the times. At the same time, we should also see that due to the active efforts of poets such as the "four outstanding poets in the early Tang Dynasty", new styles of Tang poetry have emerged, people are increasingly dissatisfied with the style of court poetry after Qi and Liang Dynasties, and the time for poetry innovation is more mature. Chen Ziang's innovative proposition at this time has not only theoretical significance, but also practical significance; It not only attacked the stale poetic style, but also opened the way for the new poets and poetic styles that were budding and growing at that time.
