They produced a large number of quasi-poems, turning literature into games in ivory towers, such as Lu Ji. His life is so chaotic, dangerous and uncertain, but his poetry is so detached and he is so reserved to show his elegance and wisdom. It should be said that they are all trying to avoid ethical pain and sink into emotional pleasure. Among these writers, only Zuo Si can be regarded as an artistic continuation of Ruan Ji's poem Yong Huai.
In the history of China literature, Ban Gu was the first person to chant history. But his poems are "wordless" (Zhong Rong). Only by thinking about these problems can Zuo Rong's poetry have its own characteristics and main brain, become a major theme in the history of poetry, and become the main means for poets to satirize the present and express their heartfelt wishes by borrowing from the past.
Zuo Si's Ode to History got rid of Ban Gu's narrative style and turned to lyricism, satirizing the present with the ancient and "stabbing the present".
Zhong Rong commented on Zuo Si, saying that "Wen Dian is based on resentment, which is quite precise and allegorical". And when talking about Tao Yuanming, he mentioned "Zuo Si Feng Zhi", thinking that he inherited the style of Jian 'an, vigorous and refined, sonorous and deeply worried. There is even an idiom "Luoyang paper is expensive" to describe the popularity of Zuo Si's writing style.
