This recognition was related to Zhuzixue(朱子學) that influenced Joseon intellectuals and revivalism in literature that had been thriving in the mid-Joseon period. Second, some scholars regarded Dufu`s poems of the post Kuizhou era as the highest level works. However, they didn`t mention why these works are excellent. In these disourses, it was a self evident fact.

These discourses had been repeated until the late Joseon period with citing Dufu`s poems of the post Kuizhou era.
