Xi Qing Shihua is quite insightful about poetry. As the saying goes, "a poet must be complacent if he cultivates himself and observes the current situation." He also quoted Huang Tingjian's poem "Sleeping on the Beach" praising Han Yu: "I don't know how to sleep in the guest room at night, but I can enjoy the sound." Another example is Meng Haoran's poem "Dongting is vast and boundless, and the weather is magnificent now", and Du Fu's poem "Shaoling has swallowed many clouds and dreams in his chest". These poetics all emphasize that poets should have life experience and true feelings, and they should be able to write vividly. "Xiqing Poetry Talk" also said: "Poetry is Zen, there is salt in water, and drinking water has salt taste." Although this theory was not created by Cai Jia, it involves the artistic characteristics of poetry, emphasizing that poetry should be implicit and intriguing. He also ridiculed that "a hundred songs are like a song, and the front is like a tail", pointing out: "Generally speaking, the contest between scraps is flat and flat, which will inevitably lead to the situation of silence. I didn't know that poets should be sentimental and arrogant. " This emphasizes the lyrical characteristics of poetry and criticizes the poetic style of being rigid in words, lacking in content and not abnormal.
Xiqing's poems also emphasize the artistic individuality of poetry creation, pointing out that "it is a family style" and "building is essential". The author thinks that artistic individuality originates from the poet's character and talent. As the saying goes, "Only with strong personality can there be limits, but not too strong". For example, although Li Bai and Du Fu stayed, they wanted to be humble but didn't want to say too much. Although Luo Yin and Guan Xiu are proud of their partiality, they are too eager to talk. The conclusion is: "There are natural people who cannot be easily changed." Although this theory is not comprehensive, it also involves an important element of creative personality. He is like "Dan Qing, chanting, and beauty are mutual"; "People's likes and dislikes are different"; "Poets might as well use common sayings"; As well as some poetry criticism, all have merits. The origin of the poems on drug names and the prevalence of definite sentences can also be used as textual research on the history of poems.
