This collection is part of the "Writings of the Three Ancient Dynasties, Qin, Han, Three Kingdoms and Six Dynasties". It was compiled by Qing Dynasty scholar Yan Kejun from various documents, covering epigraphic tablets, miscellaneous notes, books, notes, ancient annotations, classics and scriptures, and even Buddhist and Taoist scriptures, etc. Each author is accompanied by a biography, and the source of the compiled text is also indicated, which has extremely important academic value. This time, Zi'ang Culture has reorganized this huge work, canceling the division of the original works into volumes and instead dividing them according to authors to facilitate readers' examination and use.
