First, the combination of "poetry" and "history" is the unity of literariness and historicity. First of all, it is not a simple description or repetition of historical events or facts, but a literariization of historical events, which is re-understood and structured through the unique way of poetry in literary forms, and finally becomes a literary style different from history. Secondly, there are historical facts as evidence, not empty arguments or simple sensationalism. For example, Xin Qiji's "Shui Long Yin Deng Jian Kang Banquet Pavilion" fully shows the richness and discouragement of the hero's spiritual world, and deeply explores the potential function of Ci Long in expressing complex mentality.
The second is the unity of "praising history" and "expressing ambition", that is, expressing strong concern about real politics through chanting history. Praising history is the driving force, and expressing one's will is the ultimate goal. The content of "ambition" expressed in this kind of poetry is mostly the ideal of making contributions and worrying about the rise and fall of the country and the people. Whether it is Li Bai's "Antique" or Wang Wei's "Yimen Song", the poet's mind is hidden. In Xin Qiji's poems, a large number of ancient heroes were praised: Dayu, who had "eternal meritorious service", and Zhuge Liang, who had "Wolong in the dragon"; Huan Wen, who started the Northern Expedition, lamented that "the tree is still like this"; Emperor Wu of Song who devoured Wan Li; Li Guang, a flying general who recognized the tiger in front of the mountain; Lian Po, the old general who can still eat, and so on. The author praises this large number of heroes in order to express his heroic mind and ambition to make contributions to the country.
Third, the number of creative ways of ancient poetry is usually based on the scenery seen in front of us, and then the respect for the ancients leads to the reflection on the social or self-existence state of the present era. For example, although the title of the word is "nostalgia"
