What was the important literary genre and style represented by Yang Yi in the early Song Dynasty?

Yang Yi (974- 1020), a writer in the Northern Song Dynasty, is the main writer of Kunxi style poetry. Kunxi Style, represented by Yang Yi, was the most popular school of poetry in the early Northern Song Dynasty, and its poetic style, represented by Li Shangyin, dominated the whole poetry in the early Song Dynasty. Its representative, Yang Yi, has a clear-cut stand and a personality consciousness independent of imperial power, showing the typical temperament and character of scholars in Song Dynasty. The Kunxi style and the Bai style both developed in opposition and mutual penetration, and in fact they were the products of mixing the Bai style, Yishan style and Tang style. On the one hand, it attaches importance to knowledge accumulation and cultural accomplishment, which conforms to Song Wenhua's introverted trend, and on the other hand, it inherits the irony spirit of Bai poetry and late Tang poetry in the specific creative opportunity of singing in a pavilion. Yang Yi's irony in chanting epic poems and her personal feelings of chanting ancient poems can be called elegy in the prosperous times. Therefore, the Kunxi style headed by Yang Yi is not only a "simple return" to the poetic style of the late Tang Dynasty, but also contributes to the establishment of the real "Song tune". Although Quincy's poetic style has not opened up a new realm beyond Tang poetry, compared with the plain and shallow poetic style of the Five Dynasties, its elegant and dense poetic style means artistic progress after all. Under the background of the poetic style of advocating conciseness and using few allusions in vernacular Chinese and late Tang Dynasty, the appearance of Kunxi style is undoubtedly refreshing.
