What are the characteristics of Notes on Classics and History edited by Zeng Guofan?

Zeng Guofan compiled 26 volumes of Miscellaneous Notes on Classics and History, which is also a collection of essays. It was once thought that Yao Nai didn't choose the Six Classics, and the historical biography chose less and the materials were too narrow. Therefore, the miscellaneous classics are divided into 1 1, and the selected articles are mainly "practical", hoping to make up for the shortcomings of Tongcheng school literature.
