The author of Tang Dynasty is Tang Poetry, and the author of Song Dynasty is Song Poetry.
One of the differences between bold and graceful words is to look at the author. For example, Xin Qiji can't write graceful words, and Liu Yong and Li Qingzhao write bold words, which is difficult for others ~
