For example, the History of Literature in the Southern and Northern Dynasties edited by Cao Daoheng and Shen Yucheng. The general history mainly introduces a large macro development history, while the dating is much more detailed than the general history, and it will introduce more literati who will not appear in the general literature history. If I don't want to specialize in the literature of the Six Dynasties, I don't think it is necessary to read it.
Others include Nie Shiqiao's Literature History of Wei, Jin, Southern and Northern Dynasties, and Reference Materials of Literature History of Wei, Jin, Southern and Northern Dynasties published by Peking University Literature Teaching and Research Section (this book has been in the shopping cart for a long time, so I have a chance to buy it).
Third, the history of literature is divided into styles.
Five-character poems, Yuefu and parallel prose are very important styles in Wei, Jin, Southern and Northern Dynasties. Related books are Cai Zongqi's Evolution of Five-character Poems in Han, Wei and Jin Dynasties, Luo Genze's History of Yuefu Literature, and Mo Daocai's General Theory of Parallel Prose. Or not from parallel prose, but from the aspect of Ci and Fu, we can look at Cao Minggang's Introduction to Ci and Fu. (Parallel Prose and Fu are not dimensional differences, but overlapping parts. ) As for parallel prose, I miss the History of Parallel Prose in China written by Zhang Renqing, a scholar from Amway Taiwan Province Province. It is written in simple classical Chinese, which is comfortable to read and has a relatively complete system, but it may be a bit complicated to read for the first time.
If the songs were performed, the Six Dynasties would be regarded as the embryonic stage. You can look at Xue Tianwei's On Songs in the Tang Dynasty. Although the focus is on the Tang Dynasty, there are also some introductions to the embryonic stage. (Because of the style of "Gexing", the concept has always been vague, and some of Xue's divisions and distinctions are quite valuable. )
Fourth, the history of theme literature.
For example, some books that are familiar to everyone, such as landscapes, pastoral areas, immortals, sorrows and sorrows, and palaces, have never been read, and almost all of them are flipped through.
In fact, all the papers I mentioned above can be turned over. They may not be as comprehensive and systematic as monographs, but they will pay more attention to some points, but they will be relatively more detailed.
Fifth, the study of the author and so on.
Of course not "and a moment that should last forever: my historical idol Li Shangyin".
For example, Xu Baoyu's Yu Xin study, Wang Xiaodong's study and Lin's four Xiao studies are all very good.
I haven't met anyone you mentioned except Yu Xin. But believe me, these people are still quite popular in the literary circle of the Six Dynasties, so there must be research monographs, even if there is no, there must be papers!
