Tang and Song Poetry, which refer to style in addition to the concept of the times.
Style is of course related to the times, and it can't be divided by time periods.
Tang poetry started from Han Meng's poetry school and started from the Song Dynasty. In the Song Dynasty, there were also people who passed on Tang sounds, such as Bai Style and Xikun Style in the early Song Dynasty.
On the whole, the poetic styles of Tang and Song Dynasties are quite different, from the Song Dynasty to modern times.
The styles of Chinese classical poetry are generally not beyond the two categories of Tang and Song poetry.
